Problems solved by technology

Several problems of its existence are: 1, need to use a large amount of chemical cooling substances
3. Due to the large use of cooling substances and the increase of space, the passing speed of aerosol fire extinguishing substances is limited, which reduces the fire extinguishing efficiency
4. The setting of the air guide channel is specially designed, and the process requirements are high
5. High cost, low efficiency in production and handling

Embodiment Construction

[0006] The implementation process of the present invention is: 1, the carbon dioxide gas storage steel cylinder is installed in the fire extinguishing device with aerosol generator, and reinforcement, heat insulation measures are done well. 2. Connect one end of the gas pipeline to the outlet of the steel cylinder, and the other end to the aerosol release channel through the automatic release control device. 3. Start the aerosol fire extinguishing device, and the aerosol fire extinguishing substance is generated. At the same time, the automatic release control device operates to release carbon dioxide. 4. The aerosol fire extinguishing substance is mixed with carbon dioxide in the gas channel, and the temperature is greatly reduced. The mixed aerosol is released from the nozzle together to extinguish the fire.

[0007] The automatic release control device can be: 1. The outlet of the carbon dioxide release pipe is sealed by a fusible metal seal, and the seal is placed in the...

Abstract

The invention relates to a method that carbon dioxide is used to cool fire fighting hot aerosol. An aerosol generation device, a carbon dioxide storage steel cylinder and an aerosol release channel are combined into a whole through an automatic release control device, while an aerosol device has a reaction to generate aerosol fire fighting material, the carbon dioxide is released synchronously, and the aerosol fire fighting material and the carbon dioxide are fully mixed and then released together. The invention can play the cooling function to the aerosol fire fighting material, and can strengthen the fire fighting function at the same time. The weight, the volume and the cost of the whole aerosol fire-fighting device can be greatly reduced.

Description

technical field [0001] The invention relates to a method for cooling fire extinguishing hot aerosol with carbon dioxide. Background technique [0002] With the emergence of the environmental protection problem of "halon fire extinguishing agent", aerosol fire extinguishing technology, which is a substitute for halon, has been developed rapidly. Its advantages such as high fire extinguishing efficiency, no damage to the atmospheric ozone layer, and low cost have attracted worldwide attention. However, the aerosols used in fire fighting are generally hot aerosols, and the aerosols used in firefighting scenes must be safe at low temperatures, so there is a problem of how to design cooling methods. The quality of the method directly affects a series of problems such as the quality of fire extinguishing efficiency, the level of cost, and the size of the device. The cooling methods of the current fire extinguishing hot aerosol include: 1. The fire extinguishing agent in the aeroso...
