Problems solved by technology

However, due to the unreasonable chemical coolant formula and the relatively simple physical cooling structure, the temperature of the aerosol sprayed from the nozzle is still very high. It is often found that secondary fires are caused by the high temperature of the hot aerosol. How to improve the existing hot air The cooling method of the sol fire extinguishing device has become an urgent difficulty for technicians in the industry to solve

Abstract

The invention discloses a cooling method for a hot gas dispersoid fire-extinguishing device. The method is applied to the hot gas dispersoid fire-extinguishing device. The hot gas dispersoid fire-extinguishing device comprises a box body (1); a reaction barrel (3) filled with a hot gas dispersoid generating medicament (2) is arranged in the box body (1); and one side of the box body (1) is provided with a gas outlet (4). The method comprises the following steps of: improving the structure of the hot gas dispersoid fire-extinguishing device to realize physical cooling; and improving componentsand ratio of a chemical agent to realize chemical cooling. By improving the structure of the hot gas dispersoid fire-extinguishing device and the formula of the cooling agent, the temperature of a gas dispersoid passing through a nozzle is effectively reduced and the cooling effect is ideal; moreover, the cooling method is nontoxic and harmless, and has excellent safety and social benefit.

Description

technical field [0001] The invention belongs to the technical field of gas fire extinguishing in fire protection technology, and relates to a cooling method for a hot gas glue fire extinguishing device. Background technique [0002] Aerosol-type fire extinguishing agent is a newly developed type of fire extinguishing agent in the field of fire extinguishing. After the fire extinguishing agent burns and reacts, it forms a large amount of aerosol gas and completely floods the protected area to achieve the purpose of fire extinguishing. When the aerosol fire extinguishing agent burns, it will release a large amount of heat. In order to avoid the occurrence of secondary fire, the fire extinguishing agent must be cooled. The cooling method for fire extinguishing agent mainly includes chemical cooling by chemical coolant and physical cooling by structural design. However, due to the unreasonable chemical coolant formula and the relatively simple physical cooling structure, the te...
