Abstract
The invention provides a positive pressure type compressed gas bubble fire extinguisher, comprising a bubble tank body, a bubble generator, a fire extinguisher valve, a bubble nozzle and a connection pipe, wherein the bubble generator is arranged in the bubble tank body and used for feeding the premixed liquid of the bubble extinguishing agent in the bubble tank body to the bubble generator so as to form vaporous state, then impacting and mixing with the compressed gas in the bubble generator to produce the bubbles. Compared with the current bubble fire extinguisher, the positive pressure type compressed gas bubble fire extinguisher of the invention can realize the function of suppressing a fire with the same area through the premixed liquid of the bubble extinguishing agent of which the filling weight is only half of the filling weight of the premixed liquid of the current bubble extinguishing agent, and has covering performance. The speed of the sprayed bubbles is fast, the distance is far, the range is wide; simultaneously the bubbles are uniform and exquisite, and the stability is strong. The invention overcomes the shortcoming that the current negative pressure type bubble fire extinguisher influences the uniformity of the bubbles, which is caused by pressure fluctuation after absorbing air.
Description
Technical field
The present invention relates to a kind of fire extinguisher, relate in particular to a kind of positive-pressure type compressed air foam fire extinguisher.
Background technology
The kind of fire extinguisher is a lot, can be divided into by driving gas mode difference:: gas bomb formula, pressure storage type, chemical equation; Extinguishing chemical difference by being filled can be divided into again: foam, dry powder, alkyl halide, carbon dioxide, soda acid, clear water etc.
Foam annihilator is the widely used a kind of fire extinguisher of modern fire-fighting, mainly contains portable and cart type etc., by standard GB-4351.1-2005; The GB8109-2005 regulation; Some specifications and model are arranged, and all are the suction type foam annihilator, adopt the foaming of venturi ejector principle.Foam annihilator of the prior art often can't increase the gas-liquid flow range under equal air pressure, coefficient of foaming is inhomogeneous, and the foam residence time is short, can not send dry foam, and covering power is poor.For this reason; Someone has proposed a kind of suction type foam annihilator; This fire extinguisher mainly by bottle, spurt head, nozzle and the telescopic frothing head of three joints is formed, rely on the perforate of telescopic frothing heads of three joints and sidewall can send in the foam of (as 40 times) doubly, but since this pressure storage type foam annihilator adopt or the venturi ejector principle foams; The pressure that promotes gas reduces along with the prolongation of injecting time gradually; Pressure is more and more lower, and inhaled air is also fewer and feweri, and coefficient of foaming is more and more littler; Only better at injection initial stage foam performance, when the later stage, can not form foam, therefore adopt the foam stability of this suction type foam annihilator not strong, in addition, adopt this foam annihilator can not send dry foam.
For the not strong defective of foam stability that overcomes this suction type foam annihilator, the someone has proposed a kind of novel suction type foam annihilator, and this fire extinguisher is made up of housing, foam solution outlet and foam screen; Foam screen also is to adopt multistage foaming; This foam annihilator gas release is big, and good stability is a kind of foam device of high multiple; But this foam annihilator jet length is far away inadequately, has influenced its result of use.
Also the someone has proposed a kind of like this suction type foam annihilator, and this fire extinguisher is made up of foaming tube, cylinder, support and cylinder clips, adopts the straight barrel type cylinder as the foaming tube; When the divergent shape foam bump of ejection foams the tube inwall; Big energy consumption can not occur, thereby the foam jet that produces is far away, but this foam annihilator can only send in doubly foam; Gas release is big inadequately, has influenced its result of use.
