Fire-extinguishing device capable of continuously generating carbon dioxide

Abstract

ize, light weight, safe and simple operation.The invention provides a continuous carbon dioxide production device, comprising one carbon dioxide production tank, one ammonium acid carbonate feed port is installed on its top part, the feed port is equipped with one funnel device, the lower part of tank is provided with feed port and waste discharge port. The sulfuric acid feed pipe is closely inserted into feed port, the feed pipe is equipped with valve, and the end of feed pipe is connected with one cloth pipe. The wall of cloth pipe is equipped with a plurality of cloth pores. It also comprises one jacket, which is fixed on the carbon dioxide production tank, the jacket is equipped with ammonium acid carbonate feed port, which is right in corresponding to the pore on funnel device. The lowest part of said jacket is provided with sulfuric acid discharge port, and the sulfuric acid conveying pipe is connected with sulfuric acid feed pipe on carbon dioxide production tank. The invention is characterized by compact structure, smalls

Description

technical field [0001] The invention relates to a method for producing CO 2 The device belongs to fire extinguishing equipment, especially a kind of continuous production of CO by chemical method 2 Gas fire extinguishing device. Background technique [0002] CO2 is often used in applications that use a large amount of carbon dioxide to extinguish fires in the prior art. 2 The disadvantage of high-pressure gas storage cylinders is that the gas storage capacity is limited, the high pressure is dangerous, and it is inconvenient to use, especially for coal spontaneous combustion fires in coal mines and other situations that require a large amount of CO 2 Not suitable for extinguishing in the case of fire extinguishing agents. [0003] In the prior art, there is also the use of continuous production of CO by chemical methods 2 The device carries out fire extinguishing, and for example publication number is that the invention patent of CN1107642C discloses a kind of equipment ...

AI Technical Summary

Problems solved by technology

[0004] Its disadvantages are: 1) complex structure, too many pipelines and valves

2) The height of the equipment is too high, the volume is too large, and the weight is too heavy, which is not conducive to transportation and use

3) Since the chemical reaction used is relatively violent, there is no control device, the safety and stability of the operation are not easy to grasp, and the continuity of gas production cannot be guaranteed

4) The gas production process will generate pressure and use concentrated sulfuric acid, but the pressure-bearing measures and anti-corrosion measures for the equipment are far from enough. Once an explosion or sulfuric acid leaks, it will cause serious injury to the operator
