Description

Fluid conveying pressurization impact catalytic device for foam type fire extinguishing system

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 the big water yield of long distance injection got into high temperature flame, the very first time caused 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 injection can't be directed against the department of a fire and sprays and put out a fire, more causes dense cigarette to diffuse in the interior space, lets the body get into the scene of a fire personnel and flees the fact of not having the door.

(3) The method is characterized in that large water is sprayed at high pressure in a long distance to enter a fire scene, 1-3 tons of water per minute are distinguished according to the size of a water gun, and the requirement of 5 tons of water per minute of a fire-fighting big water gun causes global damage, ice disasters (such as news events causing collapse of building bodies in Harbin markets) are caused in cold areas, and news events causing large water disasters are caused in subtropical zones.

(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 filled with large water tanks, large equipment is provided with a large foam mixing tank, the odor of the foam fire extinguishing agent can cause operators to vomit, and the problem of environmental pollution is caused.

2. The second type is hydrophilic foam liquid which is generated by adopting a large-scale equipment configuration large-scale foam mixing tank high-pressure mode, and then friction foam particles are generated in a pipeline by utilizing high pressure and forming essential components in a low, medium and high-pressure foaming mode, so that the aim of rescuing and extinguishing fire is fulfilled.

3. The third type of foam is formed by mixing 1-6% of water and foam stock solution; or adopt the operation mode of hydrocone type foam gun to put out a fire, the shortcoming of this type is to adopt a large amount of water and foam mixed liquid, adopt the large tracts of land to cover the mode and can put out a fire and both pollute the environment siphon foam and put out a fire, adopt big equipment to supply water pressure, dispose siphon foam spray gun at the end of putting out a fire, produce the friction foam granule, and then reach the purpose of rescuing and putting out a fire, adopt this kind of foaming mode in essence foam and water mixed liquid, required foam stoste is in 3 ~ 10% ratio, cause the calamity sequelae of multiplicity in the extinguishing process, cause the environment big pollution more, can put out a fire and can't play the effect of rapid cooling, just as slow principle of putting out a fire relatively slow in cooling.

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 the patent only adopts a commonly configured pump, so that only one-time foam pressurization catalysis can be generated, and the density and the quantity of the foam cannot be greatly increased, so that the fire extinguishing and disaster relief efficiency still needs to be improved.
