Foam generator for compressed gas

Abstract

The invention provides a foam generator for compressed gas. The foam generator comprises a foam generator shell, a liquid nozzle, a turbulator and a compressed gas entrance, wherein the liquid nozzle is used for controlling flow rate of foam extinguishing agent premixed liquid entering the foam generator; and the compressed gas entrance is used for controlling flow rate of compressed gas entering the foam generator. The foam generator is used for enabling the foam extinguishing agent premixed liquid entering the foam generator to form rotating fog liquid, and be impacted with and mixed with the compressed gas entering the foam generator to form foam. Compared with the prior art, the foam generator for the compressed gas provided by the invention can greatly improve the mixing capacity of foam liquid and high-pressure gas, so that the ejected foam has the advantages of high kinetic energy, long ejecting distance, uniform and stable foam, high fire-extinguishing speed, high fire-extinguishing strength, long fire-retarding time, high fire-extinguishing efficiency, small use amount of foam and the like.

Description

technical field [0001] The invention relates to a fire extinguisher device, in particular to a compressed gas foam generator for a foam fire extinguisher. Background technique [0002] There are many types of fire extinguishers, which can be divided into: gas storage cylinder type, pressure storage type, and chemical reaction type according to the driving gas method; according to the different fire extinguishing agents filled, they can be divided into: foam, dry powder, halogenated alkanes, carbon dioxide, acid-base , clear water, etc. [0003] From the research progress of various fire extinguishing technologies at home and abroad, it has become a development trend to develop new types of fire extinguishing equipment that are easy to operate and highly efficient. Compressed gas foam fire extinguishing technology is an efficient and economical fire extinguishing technology. In terms of fire fighting in factories, ships, garages, and various buildings, it has great market de...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a novel compressed gas foam generator and a cart-type compressed gas foam fire extinguishing device using the compressed gas foam generator, which overcomes the cart-type fire extinguishing device used in the prior art. The foam of the foam fire extinguishing device has poor foam stability and cannot emit ultra-dry foam. Only through the control unit can the uniform foam effect be achieved, and the defects of the mixing chamber cannot be fully utilized. This new type of compressed gas foam generator and the use of this compressed gas foam generator The trolley-type compressed gas foam fire extinguishing device can greatly increase the mixing capacity of foam liquid and high-pressure gas, so that the sprayed foam has high kinetic energy, long spray distance, uniform and stable foam, fast fire extinguishing speed, high fire extinguishing intensity and long fire resistance time , high fire extinguishing efficiency, less foam consumption, etc.
