Problems solved by technology

[0011] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of assembling method of thermal aerosol coolant and thermal aerosol generating agent, overcome 1 in the prior art: when adopting external cooling mode alone, the cooling efficiency of coolant is low, The cooling channel is too long, the amount of coolant used is large, the resistance and loss of the fire extinguishing agent are large, and the fire extinguishing efficiency of the fire extinguishing device is greatly reduced; 2: When the chemical internal cooling method is used, the amount of coolant added is too much (generally In the hot aerosol generating agent formula, the chemical internal coolant does not exceed 3%) which affects the combustion stability of the generating agent and the limitation of too long reaction time; 3: The layering, fixing, filtering, Blocking and other issues

Abstract

The invention discloses a novel assembly method of a hot aerosol coolant and a hot aerosol generating agent, which comprises the following steps: step 1) pre-forming the hot aerosol coolant into small pieces; step 2) making step 1) into small pieces The thermal aerosol coolant in a discrete state is mixed with the thermal aerosol generator, wherein the amount of the thermal aerosol coolant is 5% to 50% of the thermal aerosol generator; step 3) pressing, casting or In bulk, assemble the mixture into cartridges for fire extinguishing equipment. The novel assembly method of the present invention can make the thermal aerosol coolant timely and fully exert the heat-absorbing and cooling effect when the thermal aerosol generating agent undergoes a strong exothermic reaction; at the same time, it does not destroy the continuity of each active component of the thermal aerosol generating agent Therefore, it will not have a great impact on its combustion and injection performance, which ensures the effective, fast and safe release of the hot aerosol generating agent.

Description

technical field [0001] The invention belongs to the technical field of gas fire extinguishing in the field of fire fighting equipment, and in particular relates to an assembly method of a hot aerosol coolant and a hot aerosol generating agent. Background technique [0002] Hot aerosol fire extinguishing agent (hot aerosol generating agent) is a kind of pyrotechnic agent, which will undergo a strong combustion reaction when releasing the hot aerosol generating agent, releasing a large amount of heat. In order to avoid the occurrence of secondary fires, the generating agent must be cool down. Commonly used cooling methods include chemical internal cooling, chemical external cooling, physical external cooling using refrigerant or low-temperature source, physical external cooling using structural design, physical external cooling using heat storage physical coolant, etc. [0003] As described in CN1593695A, a kind of structural design adopts a fire baffle plate and a box to phy...
