Chapter 460: It All Starts with the Smoke Curtain
"A comrade-in-arms died because of this."
This sentence was shocking enough to gain the silence of the religious members and the solemnity of everyone for Fang Huai.
Therefore, no one interrupted, and Fang Huai's voice continued.
"Modern building fires, the building is taller, more compact, less windy bungalows on all sides, many buildings, the surrounding is not open, and there are few external ventilation doors and windows, most of them are limited ventilation fires, and the combustion energy contained in building materials and decoration materials is far more than before.
From the point of view of this development, the way we used to put out fires has reached the point where we must change.
How to control the inflow of oxygen and control the airflow to change the combustion conditions has become an increasingly important issue. ”
Fang Huai said, the scene of Xiao Hei's sacrifice day also kept flashing in his mind.
A small building with three floors and a mezzanine, with a large internal space, but there are compartments, and there are three windows in total, which have not yet been fully opened.
Typical of a fireground with limited ventilation.
Now that I think about it, if the door is closed and the conditions for oxygen inflow are reduced, the fire will definitely burn smaller and smaller, and although the people inside will be dangerous, a small amount of time in the anoxic environment is not enough to kill.
At least not more dangerous than a rapid increase in temperature.
But what were you doing that day?
When he arrived, the door was wide open, Xiao Hei was attacking inside, Hao Chengbin and Zhao Jincheng were standing at the door to control the temperature, and the water gun was blooming.
Maintain a cooling doorway for internal attackers, which is currently known as "gated control".
At that time, no one felt that it was wrong, because everyone learned that water guns should cool people down and create safe passages.
But everyone, including Fang Huai, ignored why a fire with limited ventilation should obviously not have enough oxygen, but it could burn more and more fiercely, without a tendency to weaken at all.
It is precisely because of the open door and the two multi-functional water guns that they are constantly shooting wildly with big flowers, sending air into it with water pressure!
They felt that it was to leave a door for Zhou Yong to retreat, and they became the king of Hades who wanted his life.
"In addition, in the past, we believed that internal attack is to break the door, and ventilation is to open the window.
In fact, any number of openings in the structure of a fire building will increase the rate of heat release, and the door, which is also a vent, will change the path of smoke.
Especially when air with a certain pressure enters, the flow speed of the air will suddenly increase more than ten times!
The smoke is gushing, coming out of the door, and the firefighters enter through the door, so what kind of hot and toxic environment will the firefighters be in? How many degrees of scorching will the combustible materials of the entire path undergo?
Therefore, ventilation and smoke exhaust must consider the strength of the first disposal force, and cooperate with the fire extinguishing instructions, once the ventilation is carried out without authorization, the fire will soon get out of control and put the personnel in danger.
The door must be controllable, it needs to be opened briefly when entering and exiting, and then closed immediately, when it is necessary to exhaust smoke, open the window for one-way smoke exhaust, in order to create a stable one-way ventilation path, otherwise, the smoke is uncontrollable, and similarly, the fire is uncontrollable.
That's the real gated knowledge.
Not a simple gating, but control of high-temperature flue gas and oxygen! ”
Fang Huai said, almost wanting to give himself two slaps.
Everyone said that after Zhou Yong went in at that time, the covering group continued to shoot water to cover, and the fire began to be fierce again, as if it was coming towards him.
Probably because the air was pressed into the fire again through the door, causing internal pressure and making the smoke disorderly again.
In fact, he didn't have to go in desperately that day, as long as he arrived at the scene, closed the door during Zhou Yong's first internal attack, leaving only the crack in the door where the water gun entered, and then cooled down the floor slab on the second floor as a whole, although the water vapor may temporarily burn Zhou Yong, but the oxygen reduction and continuous cooling, the fire will definitely develop in another direction!
Deal with it like this, when Zhou Yong enters the fire for the second time, there will be a qualitative change in the survival situation inside, maybe it will not be dangerous anymore, perhaps, he doesn't need to retreat in a hurry at all, he can wait for his comrades to come to the rescue.
The obvious mistakes and omissions caused by this lack of knowledge made Fang Huai regret it.
Zhou Yong was brave, but he did not die of bravery, but of ignorance.
The ignorance of comrades-in-arms.
But the comrades-in-arms don't want to be ignorant, they lack the right knowledge to learn.
Fang Huai's words today are to be heard by the 46 commanders present, and even more, to be heard by the commanders of the whole school.
The flow path of smoke has not yet formed a detailed theory in any corner of the world today, and the religious staff naturally has no way to refute it, so they can only be listeners, but the future commanders next to them are obviously more interested.
A curious cadet broke the silence.
"So you're saying you can't shoot flowers at the door?"
When Fang Huai heard the question, he came back to his senses and said:
"It's not that you can't shoot, it's that you can't press too much, and you can't shoot the goal, the water pressure is high, the shooting area is wide, and the door is strafing, is it pushing the air into it quickly?"
"But what we learned from the recruits is to enter the fire with two guns, one in front of the flower, one in the back, bloom to cover the attack, prevent the impact of the flames, and hit the fire source, just like a 100-meter echelon attack exercise, it has been so long, it is also very useful, and the door will not let the shot bloom in the future, who will cover the internal attack?"
Everyone's curiosity made Fang Huai's face smile again:
"When covering, you should use the gated operation method to enter tentatively, and after the water cannon enters the door to shoot water to cool down, you can enter the operation inside, and the water shooting method of the gated operation and the transitional attack should be tailored to the specific situation, and the religious staff should be able to talk about it.
All I can say is that the nozzle should be as close to the inside of the fire as possible, and the angle should be constantly adjusted to shoot water diagonally towards the ceiling, which is a way to limit the air entrained by the jet and cool down quickly.
Moreover, in the past, a group of guns covered, a group of guns to attack the pattern is not unchangeable, as long as a multi-functional water gun can be designed to bloom at the same time, it can bloom, can be direct, can also be set up on the edge of the nozzle to bloom, in the middle of the DC, you can cover your own attack, enhance mobility. ”
"Hmm..."
The idea of adding a DC belt to the multifunctional water gun to bloom is wow.
If there is one more gun like this, if it is easy to use and the firing pressure is stable, it will undoubtedly be the gospel of the squadron that has not yet been formed, not to mention whether there is any saving people, whether there is more flexibility, and one less cover gun, and when dealing with a fire, the hose can be reduced by several plates, right?
The discussion gradually began to be heard, and the thinking gradually became active, and before the religious staff could control the situation, some people continued to ask questions.
"That door has to be opened and closed, and someone has to be set up to open and close the door? We don't have enough manpower, and we have to add a security officer to close the door? And the door is closed, so you can't see it inside? ”
"You don't have to add people." Fang Huai shook his head and said:
"In Europe, there is a kind of smoke curtain, which is supported by a wide ejector rod on the door frame, which is easy to hang and is resistant to fire, as long as it is hung, there is no need to open and close the door repeatedly.
After people pass, the curtain will naturally hang down, and such a block can give people the greatest sense of security and will not affect the entry and exit.
As for what you said you can't see, adding a flashlight to the inside of the door will solve the problem. ”
"Oh..."
People have thought about it comprehensively, and the relevant equipment has been thought out.
No wonder, it can be favored by the upper leadership.
At this time, the religious staff smiled: "Comrade Fang Huai, ideas are ideas, and they have to be implemented, but there is still a distance, I want to ask, have you counted the production line in your creative ideas?" The fire department does not have a purchase order, who will make the production line for the equipment? Even if it is purchased, if the testing phase is not good, who will take care of it? ”
When Fang Huai heard this, he couldn't help but let out a long sigh.
When he spoke, there was no trace of respect and mockery in his language.
"Religious member, do you know what you advocate about Western thought, and where we should learn the most?
This smoke curtain is not promoted by the government, its promoter is an insurance company, because the insurance company has researched and explored, it believes that it can better protect the affected houses, so it sponsors the government to buy this smoke curtain, and sponsors the smoke exhaust machine production company, in each positive pressure smoke exhaust machine sales, will be equipped with a piece of such a smoke curtain.
The openness of the West lies in not being bound by ideas, and that there are interests in the future, and that conditions will be created to do it, rather than sitting here for 10,000 reasons why it cannot be done.
At the same time, because of the encouragement of such ideas, the creativity of modern science has been enriched, and the scientific and technological catch-up has been completed.
Of course, since I mentioned it, I thought of a way, my father happened to have a company that was ready to buy industrial production lines, and I can guarantee that the gun I am talking about, and this smoke curtain, will be available in China within half a year, and as for whether the fire department will purchase it, that is not something I can decide.
In addition, I will also write a detailed report on today's discussion and submit it to the leaders, starting from these two classes, talking about this smoke curtain, describing the necessity of fire scientific research, promoting the private spontaneous research market, rejecting the monopoly of some companies, and allowing more self-developed companies to profit. ”
Fang Huai said, his tone gradually firm.
That's it.
The fire-fighting equipment company that has been planning, and the exhortation of the fire-fighting scientific research environment, started with this gun and this smoke curtain.
The exclamations around, wave after wave.
This Nima, ruthless!
People still have a company at home, and if they don't agree with each other, they have to start working!
Also write a report to the leader!
What is the combination of theory and practice?
That's it!
The religious officer's face finally couldn't hold back.
What report do you write on this? What to write a report? Do you want to my material?
Fang Huai's opening was to acquire the industrial production line, and finally made him realize that the strength behind this guy was amazing.
Yes, no matter how good he is, it is too difficult for him to catch the line of leadership, and he has a relationship with the upper echelons!
"Comrade Fang Huai, there is a problem with your words, and no one will sit idly by in the face of problems! Just solve the problem, you need to think comprehensively, and use a reasonable way!
… However, the original intention of developing the social cause of fire protection is good, you are a talent, what ideas do you have, you can say it, the school teaching and research team will support you, come to the office later, we can talk. ”
It is impossible to admit it in public.
But the words of the religious staff became softer and softer the more they spoke, and even the exclamation gradually disappeared.
The surrounding is not a simple student, but the escort students are recommended by the unit, even if it doesn't matter, at least they have to get along well with the leaders of the unit, and they all have the ability to listen.
Who can't see that the attitude of the religious staff has changed?
All of them sighed in their hearts.
Big guy, this is big guy.
Fang Huai's idea is actually much simpler.
He definitely has the ability to make small reports, and he definitely wants to write reports, but he is not here to fake the tiger.
It's just a matter of how it's written.
At this moment, he just squinted and thought about what value this religious member had that was worth squeezing.
After a while, Fang Huai said: "Teacher, I have an idea, I don't know if your teaching and research team will support it?" ”
The religious member's heart trembled.
"Where?"
"Kun refers to the Fire Research Institute." Fang Huai's words were concise and to the point.
The religious staff were all in their hearts.
If you can get indicators for this, who wouldn't want to?
But now the three fire research institutes in the country, Shanghai, Chengdu, and Tianjin, are public institutions, and they are directly subordinate units of ministries and bureaus, and the leaders in them are experts who get GWY allowances, do you think it is so easy to get?
“… It's a good thing if you can do it, but I hope your ideas are realistic, so let's talk about it for a while. ”
"Okay, teacher."
Fang Huai was also simply, and sat down after speaking.
He wasn't actually prepared to do anything big, and the religious staff probably didn't have the ability to do so.
Just need a serious scientific research unit that can support their own company's research, that is, there is only one office in Kunzhi listed units, for Kunzhi, a few more activities, for him, there is an official cooperative research name, in the future, the company's research and development of equipment, it is easier to enter the fire brigade, accepted by the majority of officers and soldiers.
Moreover, in the report of scientific research-related reports, it is best to have the signature of a school, so as not to go all the way, it is your own family's words.
He now realizes the importance of "theories need to come from".
The school is undoubtedly a good source of creation theory, and if there is a scientific research unit here, then what you lack in the future can be made up here.
I believe that the school will not refuse, and the development of a school needs these research results as the cornerstone very much.
I also have a set of theories on fire dynamics here, and according to the information I have learned, many of them are still being explored by Western countries, and I can slowly release conjectures according to the development of theories, and within a year or two, a series of advanced achievements will be born.
It is difficult to start, but you can set up the company first, build your own laboratory to demonstrate a part, as long as you are on the right track, the foundation of cooperation between the two sides will become more and more solid.
The religious staff continued to attend classes and did not call Fang Huai by name.
Fang Huai was also quietly comparing the textbook published in the early 2000s, marking some theories that needed to be revised and updated.
The classroom is in harmony.
Flipping the table is the premise of harmony.
……
At noon, Fang Huai came out of the religious officer's office with a smile on his face.
The fire theory has not been mentioned for the time being, this thing, the results are not on the ground before the ground, but the production line, it is very specific, Fang Huai promised that as long as the school has a scientific research institute, the company's research results, research and development equipment, can be shared in the name of joint research between the two sides, and the profits from the sale of equipment can also be given back to the school 20%.
Moreover, the company's upfront investment in 09 years alone will not be less than 50 million.
The school only contributes a name, zero investment, and the only thing to contribute is to apply to the higher authorities for a ten-person research institute.
In this establishment, some excellent faculty members can also work part-time, and they can only give some additional expert subsidies, and they will hardly need any money.
As long as the school reaches a consensus, Fang Huai promised to let his father come and sign a cooperation intention before leaving.
This matter, the school basically has zero risk, can do it, and sit and wait for the money to be collected in the future.
Without even hesitation, the religious staff agreed to ask for instructions and reported, and hurriedly went to the leader.
After Fang Huai finished his work, his mood was much more relaxed, and after thinking about things for a long time, he was finally about to officially start.
In the future, I will have to spend some military merit points to exchange for some advanced equipment materials as "research results", and with the name of the school, it should be easier to get the procurement target.
Thinking all the way, I went back to the dormitory.
As soon as he pushed the door open, Yang Tao was babbling.
"Fang Huai, why did you come back? Someone from your team is here, so I'm asking you to take a group photo! Damn, you still have a big face, your team is waiting for you downstairs! Go for it! ”
