Low-concentration gas heat source skid heat supply device

Abstract

The invention discloses a low-concentration gas heat source skid heat supply device. The low-concentration gas heat source skid heat supply device comprises a coal burning device, a heat source skid and a heat storage oxidization device. The coal burning device comprises a coal burning air furnace, a heating device, a first belt disc, a second belt disc and a conversion gear case. The coal burningair furnace is connected with a gas generation device. The gas generation device is connected with an air pressure motor. The air pressure motor is connected with the first belt disc. The first beltdisc is connected with the conversion gear case. The conversion gear case is connected with the second belt disc. The second belt disc is connected with an air pressure pump and a power generator. Theair pressure pump is connected with the gas generation device, and the gas generation device is connected with the heat source skid. The heat source skid comprises a shell, a heat flow one-way interrupter and a plurality of oxidization chambers, wherein every two adjacent oxidization chambers are separated through a heat isolation plate, and elevator arcs are arranged in the oxidization chambers.The low-concentration gas heat source skid heat supply device solves the problem that due to the too low concentration of methane in the low-concentration gas in coal mine, the utilization technologydifficulty is large; and meanwhile, the greenhouse effect is relieved, and pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of gas treatment, in particular to a low-concentration gas heat source skid heating device. Background technique [0002] China has the third largest coalbed methane reserves in the world, and the prospect of coalbed methane development is very promising. However, in 2004, about 1.6 billion cubic meters of coalbed methane was developed underground in the country, and the average rate of coalbed methane development in state-owned mines with high gas outbursts was only about 10%. From a global perspective, the utilization of coal mine gas is mainly concentrated in civil, power generation, industrial fuel and chemical raw materials, etc. The most reasonable way to utilize coal mine gas is power generation. The methane content of coal mine gas discharged from coal mine ventilation is generally less than 1%, which is called wind exhaust gas (commonly known as "air exhaust"). The total amount of methane discharge...

Problems solved by technology

[0003] The purpose of the present invention is to provide a low-concentration gas heat source skid heating device, which solves the problem that the low-concentration gas in coal mines is difficult to use because the methane concentration is too low, and at the same time makes full use of the low-concentration gas to slow down the greenhouse effect. , thereby reducing the pollution to the environment
