Abstract
A distributed combined cooling, heating and power energy system for gas extraction in a coal mining area, which belongs to an energy system for gas production. A gas extraction pump station, a gas storage tank, a water-sealing flame arrester, a wire mesh filter, a first pipeline flame arrester, a wet-type bleeding valve and a cyclone dehydrator are sequentially connected; an outlet of the cyclone dehydrator is divided into two branches, one branch sequentially connected with a second pipeline flame arrester, a proportioning mixer, a gas power machine, a waste heat boiler and a waste heat-type double-effect lithium bromide absorption water chiller/heater unit, and the other connected with a gas-type double-effect lithium bromide absorption water chiller/heater unit; a first power generator is connected with the gas power machine, a water storage tank outlet is connected with a pressurizing pump, a second power generator is connected with a steam turbine and driven by the steam power machine to generate power, and cold/hot water of the waste heat-type water chiller/heater unit and the gas-type water chiller/heater unit is delivered through an energy supply pipeline after collection and mixing. With the power energy system mining area, clean production and utilization of coal-mine gas and economic development of coal mine areas are realized.
