Fire prewarning and fire extinguishing system based on industrial CO2 collection capable of relieving climate change

Abstract

The invention discloses a fire prewarning and fire extinguishing system based on industrial CO2 collection capable of relieving climate change. The system comprises a waste gas collecting device, a dust filter device, a combustion purifying device, a mated fire prewarning device and a control management system connected through waste gas emission pipes; waste gas leaded out from the combustion purifying device is fed to a gas-water separator by a cold accelerant filter device and a buffer; one exhaust way of the gas-water separator is fed in carbon dioxide liquefying equipment, the second exhaust way is injected in a pressure storage tank with sodium chloride water solution, and the third exhaust way is connected with a gas-state carbon dioxide storage tank; liquid-state carbon dioxide output from the carbon dioxide liquefying equipment, gas-state carbon dioxide output from the gas-state carbon dioxide storage tank and mixed solution output from the pressure storage tank with the sodium chloride water solution flow to a fire extinguishing nozzle by pipelines; and the control management system receives fire prewarning signals, and controls the fire extinguishing nozzle to extinguishfire. The system can prewarn fire in factories and forests around the factories, uses carbon dioxide in industrial waste gas for fire extinguishing, and meanwhile, can relieve such climate deterioration problems as greenhouse effect caused by CO2.

Description

technical field [0001] The invention relates to the collection and utilization of industrial waste gas, in particular to a system for using carbon dioxide collected from industrial waste gas to extinguish fires in factories and surrounding forests. Background technique [0002] Many industrial waste gases contain high concentrations of carbon dioxide. The emission of these carbon dioxide into the atmosphere not only pollutes the environment, causes "greenhouse effect", but also wastes carbon dioxide resources. Recycling of carbon dioxide is the main point of implementing the concepts of energy saving, emission reduction and resource recycling. The recovered and purified carbon dioxide has a wide range of uses, mainly including mechanical protection welding, mechanical mold casting, gas injection and oil production in oil fields, dry ice preservation for food, agricultural gas fertilizer, low-temperature storage of medicine, filling and aeration of beverage beer, chemical pro...

Problems solved by technology

However, for industrial parks that are closer to the forest, they are generally relatively remote, and the cost of transporting carbon dioxide after separation is high. However, there may not necessarily be factories that need carbon dioxide in the same park or similar parks, and even if there are, it may not be able t...
