Description

Technical Field

[0002] Coalbed methane refers to hydrocarbon gas stored in coal seams with methane as the main component, mainly adsorbed on the surface of coal matrix particles, and partially free in coal pores or dissolved in coal seam water. It is a coal-associated mineral resource and an unconventional natural gas. Since coalbed methane mining will destroy the integrity of coal rock, coal powder will inevitably enter the gathering and transportation pipelines and mix into the coalbed methane. The coal powder mixed in the coalbed methane can easily damage equipment such as compressors, cause damage and malfunction of production equipment, and reduce production efficiency. Therefore, filtering coal powder is particularly important. Most of the existing coalbed methane filtration devices use a filter box combined with a filter mesh for filtration.

[0003] However, when using the existing filter, a lot of coal powder is easily attached to the outside of the filter screen, and the coal powder is not easy to clean when the equipment is running, which affects the filtering effect.
