Problems solved by technology

There are also a small number of mining areas that use carbon dioxide for fire prevention and extinguishing. The converters used to convert liquid carbon dioxide to gaseous carbon dioxide are all heating devices located on the upper part of the converter or mostly large heaters for centralized heating. This makes even if the converter uses a circulation pump, The water temperature in the upper part is also always higher than the water temperatu

Abstract

The invention relates to a liquid-gas state converter of carbon dioxide/nitrogen and a conversion system. The converter comprises a casing. Liquid inlet pipes and gas exhaust pipes are arranged; a heat exchange device is arranged in the casing; a heater is arranged below the heat exchange device; a heating pipe of the heater is located below the heat exchange device; the conversion system comprises a plurality of converters; the liquid inlet pipes of the plurality of the converters are connected with one conveying pipe; the gas exhaust pipes of the plurality of the converters are connected with a conveying pipe; each converter is provided with a monitoring cabinet; and the monitoring cabinets can monitor the working conditions and the working parameters of the converters and automatically control and regulate the operation of the converters according to the detected working parameters. According to the converter and the conversion system, the heat energy loss is small, the heat efficiency is high, and the energy-saving effect is good; and the conversion system can realize automatic segmentation control and regulation according to the operation state of the system and can also realize automatic control of all parameters of output gaseous carbon dioxide/ nitrogen. The converter and the conversion system are mainly applicable to fire prevention and extinguishing under mines.

Description

technical field [0001] The invention relates to a converter and a conversion system for converting liquid carbon dioxide / nitrogen to gaseous carbon dioxide / nitrogen, which are mainly used for fire prevention and extinguishing in underground mines. Background technique [0002] At present, the common method of fire prevention and extinguishing for spontaneous fires in coal mines in my country is to inject nitrogen into the goaf, but the comprehensive cost of mine nitrogen fire extinguishing equipment (especially nitrogen production equipment) is relatively high. There are also a small number of mining areas that use carbon dioxide for fire prevention and extinguishing. The converters used to convert liquid carbon dioxide to gaseous carbon dioxide are all heating devices located on the upper part of the converter or mostly large heaters for centralized heating. This makes even if the converter uses a circulation pump, The water temperature in the upper part is also always high...
