Technical field
The utility model belongs to the fire prevention field, is specifically related to a kind of gas formula high power foam generator of providing for oneself.
Background technology
High expansion foam fire-extinguishing system has characteristics such as extinguishing ability is strong, speed is fast, cost is low, water loss is little, pollution-free; It is the first-selected fire-fighting equipment in large-scale places such as hangar, garage, oil depot, mine, oil, liquefied gas station, oil jetty, library, archives; High power foam generator plays an important role to stamping out a fire as the key equipment of fire extinguishing system.
At present, existing high power foam generator has two kinds of patterns on the market, a kind of high power foam generator for hydraulic turbine driving, and another kind is motor-driven high power foam generator.Thereby they all are the needs that drive the satisfied foaming of air-flow of motion through the rotation of fan blade.The former has good reliability, but air quantity and blast receive the influence of rotational speed of water turbine bigger; Latter's air quantity and wind pressure ratio are more constant, but reliability is relatively poor, generally need double circuit power supply, and in GB and national military standard, have stopped its use.The high power foam generator structure of these two kinds of patterns is more complicated all, and is bulky, and must be installed in the good place of ventilation condition, can't satisfy the needs that small space is installed and enclosure space uses.
Summary of the invention
To above technical problem, the purpose of the utility model be to provide a kind of simple in structure, volume is little, do not receive the gas formula of providing for oneself the high power foam generator of ventilation condition restriction.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
A kind of gas formula high power foam generator of providing for oneself; It is characterized in that; Comprise gas cylinder and foaming tube, the oral area of said foaming tube is provided with foam screen, and the foam solution injection unit that in the foaming tube, outside foam screen is provided with, connects spurts the unit with the gas that is communicated with gas cylinder.
The characteristics of the utility model are with further improving:
Said foam screen is a zigzag.
Said foam solution injection unit spurts between unit and the foam screen at gas.
Said gas spurts the unit and is included in a plurality of shower nozzles and corresponding gas service pipe that foaming tube cross section is evenly arranged.
Said foam solution injection unit is included in a plurality of nozzles and corresponding foam solution arm that foaming tube cross section is evenly arranged.
The afterbody of said foaming tube is provided with cover plate.
Said gas cylinder outlet is provided with pressure-reducing valve.
Gas in the said gas cylinder is air, nitrogen or inert gas.
The gas formula of providing for oneself the high power foam generator of the utility model; The gas that adopts the gas cylinder storage is after decompression; Provide foaming required blast and air quantity to high power foam generator; Blast apparatus that need not be special, the fire extinguishing system that constitutes thus is simple, cost is low, easy to maintenance, safe and reliable, is applicable to confined space; The fire extinguishing system simple and flexible that constitutes thus, volume is little, also is applicable to places such as naval vessel, hangar, garage.
