Coal mine air inlet wellhead temperature adjustment system

Abstract

Coal mine air inlet wellhead temperature adjustment system, including the exhaust air heat exchange chamber, the exhaust air heat exchange chamber is equipped with a exhaust air heat exchanger, and the outlet of the heat exchange pipeline of the exhaust air heat exchanger passes through the delivery pipeline and the four-way valve. One port is connected, the inlet of the heat exchange pipeline of the exhaust air heat exchanger is connected with the outlet of the heat exchange pipeline of more than one air heat exchanger through the connecting pipeline, and the inlet of the heat exchange pipeline of each air heat exchanger The other port of the four-way valve is connected to the outlet of the compressor through the pipeline, and the other port of the four-way valve is connected to the inlet of the compressor through the pipeline. The heat exchangers are respectively arranged at the air inlet of the air inlet chamber or in the channel in the air inlet chamber. Its purpose is to provide a coal mine air inlet wellhead temperature adjustment system that can save a lot of energy by extracting continuous and stable huge amount of heat energy resources from the exhaust air coming out of the mine return air trunk to heat the air supply of the coal mine inlet air trunk.

Description

technical field [0001] The invention relates to a coal mine air inlet wellhead temperature adjustment system. Background technique [0002] The "Coal Mine Safety Regulations" stipulates that the air temperature of the mine must be above 2°C below the air inlet wellhead; the air temperature of the mining face of the production mine shall not exceed 26°C, and the air temperature of the electromechanical equipment chamber shall not exceed 30°C. Therefore, in winter, it is necessary to heat the air entering the main air inlet of the coal mine, and in the hot summer, it is best to cool down the air entering the main air inlet of the coal mine. The existing air supply to the main air inlet road of the coal mine uses mine air preheating equipment such as coal-fired boilers to preheat the air entering the mine in winter, and exists in the exhaust air discharged from the main return air road of the mine. Continuous and stable A huge amount of thermal energy resources are directly di...

AI Technical Summary

Problems solved by technology

The existing air supply to the main air inlet road of the coal mine uses mine air preheating equipment such as coal-fired boilers to preheat the air entering the mine in winter, and exists in the exhaust air discharged from the main return air road of the mine. Continuous and stable A huge amount of thermal energy resources are directly discharged, resulting in huge energy waste and increased environmental pollution

In addition, in the midsummer season, the process of cooling the air entering the mine also consumes a lot of energy
