Abstract

The invention discloses a mobile coalbed methane extraction device. The mobile coalbed methane extraction device comprises a particulate matter filter, a first compressor, a second compressor, a carbon dioxide filtering tower, a heat exchanger, a heating device, a first control valve and a second control valve. The gas outlet end of the particulate matter filter is connected with the gas inlet end of the first compressor, the gas outlet end of the first compressor is connected with the gas inlet end of the carbon dioxide filtering tower, the first end of the first control valve is communicated with the top of the carbon dioxide filtering tower, the other end of the first control valve is connected with the gas outlet end of the first compressor and the gas inlet end of the carbon dioxide filtering tower respectively, the gas outlet end of the carbon dioxide filtering tower is connected with one end of the second control valve, and the other end of the second valve is connected with the heat exchanger. The mobile coalbed methane extraction device is simple in structure and convenient to use and can extract coalbed methane without using any explosives or dangerous gas, thereby being high in extraction speed and efficiency and effective in resource utilization and achieving the green and environment-friendly production of resources.

Description

technical field [0001] The invention relates to a coal bed gas mining device, in particular to a mobile coal bed gas mining device. [0002] Background technique [0003] Coalbed methane refers to unconventional natural gas stored in coal seams with methane as the main component. It is a kind of natural gas and is the main gas produced in the coal chemical production process. It coexists with coal and is also called gas. Coalbed methane is a high-quality energy and chemical raw material. The reserves are extremely rich. According to analysis, my country's coalbed methane discharged into the atmosphere every year accounts for one-third of the total coalbed methane emitted by coal mining in the world. The greenhouse effect caused by the main component of coalbed methane entering the atmosphere has not only caused great environmental problems , is also a great waste of resources. At the same time, the casualties caused by underground accidents caused by gas are also very h...
