Description
Technical Field
The invention relates to a fluid conveying pressurization impact catalysis device for a foam type fire extinguishing system, in particular to a fluid conveying pressurization impact catalysis technology which can perform pressurization impact catalysis on foam concentrate to obtain high-density fine mist foam with greatly increased foam density and quantity.
Background
The traditional fire fighting truck extinguishes fire by bearing a large water tank; or the fire-fighting equipment with large volume is taken as the main part, and a high-pressure large water source is adopted for long-distance spraying to achieve the cooling mode, thereby achieving the purpose of rescuing and extinguishing fire; however, the fire extinguishing mode does not achieve the effect of quick fire extinguishing. Generally, the conventional device also causes a plurality of disaster sequelae during the fire extinguishing process, and causes the following disadvantages:
(1) The traditional fire fighting truck has the defects that the volume is huge, the large water tank is borne, the large equipment is slow in movement, so that the fire fighting truck cannot arrive at a fire scene quickly for rescue and fire extinguishment, and the first time for rescue and fire extinguishment can be lost when the fire fighting truck meets narrow road conditions and roadways.
(2) During big water yield entering high temperature flame is sprayed in long distance, the very first time causes flash fire in the twinkling of an eye, and produced high temperature flame must spread the scene of a fire in the twinkling of an eye, causes personnel's injury, and the disappearance of long distance spraying can't be directed against the department of a fire and spray the fire extinguishing, more causes dense smoke to diffuse in the interior space, lets the body sink into the fact that the scene of a fire personnel fleed and do not have a door.
(3) The method is characterized in that large water is sprayed into a fire scene at high pressure from a long distance, water is sprayed into the fire scene at high pressure, the water is about 1 to 3 tons per minute according to the size of a water gun, and the demand of 5 tons per minute of water for a fire-fighting water cannon causes global damage, ice disasters (such as news events causing collapse of building bodies in Harbin markets) are caused in cold regions, and news events causing large water disasters are caused in subtropical regions.
(4) For a fire fighting truck which bears a large water tank and is provided with large-volume equipment, because the water consumption is large, the water supply source is difficult, and in addition, the water taking is difficult and the operation is complex, the fire extinguishing efficiency is poor.
Known foam extinguishing agents include the following classes, as is known:
1. the first type is a foam fire extinguishing agent extracted from animal fat protein, which is used for carrying large water tanks, large equipment is provided with a large foam mixing tank, and after fire extinguishment, odor of the foam can cause operators to vomit, and further causes the problem of environmental pollution, and the foam is stopped being used in advanced countries.
2. The second type is hydrophilic foam concentrate which is generated by adopting large equipment to configure a large foam mixing tank in a high-pressure mode, and then friction foam particles are generated in a pipeline by using a high-pressure foaming component in a low-pressure, medium-pressure and high-pressure foaming mode to achieve the purpose of rescuing and extinguishing a fire, the foam concentrate is a foam and water mixed liquid by adopting the foaming mode, the required foam concentrate is mixed at the ratio of 3 to 10 percent, multiple disaster sequelae are caused in the fire extinguishing process, environmental pollution is caused, although the fire can be extinguished, the effect of quickly reducing the temperature cannot be achieved, and the principle that the temperature is reduced slowly relative to the fire extinguishing speed is good.
3. The third type of foam is prepared by mixing water and 1 to 6 percent of foam stock solution; or adopt the operating mode of the siphon type foam gun to put out the fire, the disadvantage of this kind of type is to adopt a large amount of water and foam mixed liquid, can put out the fire and already pollute the environment siphon foam to put out the fire by adopting the large-area covering mode, adopt the water pressure of large-scale apparatus supply, dispose the siphon foam spray gun at the end of putting out the fire, produce the friction foam granule, and then achieve the goal of rescuing and putting out the fire, adopt this kind of foaming mode to be foam and water mixed liquid in fact, the proportion of necessary foam stock solution is in 3-10%, cause the calamity sequelae of the multiplicity in the course of putting out the fire, cause the environment to pollute greatly, can put out the fire and can't get the result of fast cooling, it is good for the slow principle of putting out the fire to cool down slowly.
To overcome the above-mentioned drawbacks, the present inventors developed a patent as shown in "improvement of configuration structure of fire-fighting motorcycle" model M477420 in Taiwan. Although the patent can reduce the resistance of the foam concentrate during the transportation by simplifying the components and the pipeline structure and changing the injection direction of the foam concentrate, the density and the quantity of the foam in the foam concentrate are increased, thereby enhancing the fire extinguishing and disaster relief efficiency to a limited extent; however, the pump of this patent only adopts the general configuration, so only can produce disposable foam pressurization catalysis effect, so can't increase foam density and quantity by a wide margin, and the efficiency of fire fighting and disaster relief still need to be improved.
