MINE AREA DISTRIBUTED COMBINED COOLING HEATING POWER ENERGY SYSTEM FOR EXTRACTING GAS FOR COAL MINE

摘要

Disclosed is a mine area distributed combined cooling heating power energy system for extracting gas for a coal mine. A gas extracting pump station (1), a gas storage tank (2), a hydraulic seal-type arrester (3), a silk screen filter (4), a first pipeline fire arrester (5), a wet bleeder valve (6) and a whirlwind dehydrator (7) of the system are connected in sequence. An outlet of the whirlwind dehydrator (7) is divided into two paths, and one path is connected to a second pipeline fire arrester (8), a proportioning mixer (9), a gas power machine (10), a waste heat boiler (12) and a waste heat type double-effect lithium bromide absorption type hot and cold water unit (18) in sequence, the other path is connected to a gas type double-effect lithium bromide absorption type hot and cold water unit (19); a first generator (11) is connected to the gas power machine (10), and an outlet of a water storage tank (16) is connected to a pressurizing pump (17); a second generator (14) is connected to a steam turbine (13), and a steam power machine is used for driving to generate electricity; and after being gathered and mixed, the cold water and the hot water of the waste heat type double-effect lithium bromide absorption type hot and cold water unit (18) and the gas type double-effect lithium bromide absorption type hot and cold water unit (19) are transported through an energy supply pipeline. The mine area distributed combined cooling heating power energy system for extracting gas for the coal mine realizes clean production and use of the gas of the coal mine and economic development of a coal mine area.
