Efficient dehydration device for coal bed gas ground gathering and transportation and use method of efficient dehydration device

Abstract

The invention discloses an efficient dehydration device for coal bed gas ground gathering and transportation and a using method thereof.The efficient dehydration device comprises a filtering dehydration box with the top open and a first dehydration box with the top open, and the top of the filtering dehydration box is fixedly connected with a first cover plate; the top of the first dewatering box is fixedly connected with a second cover plate. The coal bed gas dehydration device can effectively perform dehydration operation on coal bed gas in a mode of matching heating dehydration with cooling dehydration, achieves the purpose of efficient dehydration, can improve liquefaction stability and reduce the phenomenon that adhesion dehydration cannot be continued due to the fact that more water drops adhere to the coal bed gas in a mode of automatically shaking water drops in the dehydration process, and improves the dehydration efficiency of the coal bed gas. According to the coal bed gas dewatering device, impurities in coal bed gas can be conveniently filtered before dewatering, the filter screen can be automatically knocked and vibrated during filtering, and the risk that the filter screen is blocked by static accumulation of the impurities due to static filtering is reduced.

Description

technical field [0001] The invention relates to the technical field of high-efficiency dehydration equipment, in particular to a high-efficiency dehydration device for ground gathering and transportation of coalbed methane and a method for using the same. Background technique [0002] Coalbed methane is an important resource that can be exploited and utilized. Coalbed methane is stored in coal seams, with methane as the main component. The coalbed methane mined in natural state contains a lot of moisture and dust. In order to improve the utilization rate of coalbed methane resources and prevent water CBM and dust may cause subsequent equipment blockage or water hammer and other hidden dangers. Usually, the CBM needs to be treated to remove moisture and dust in the CBM. When dehydrating, a dehydration device is required; [0003] Existing dehydration devices for ground gathering and transportation of coalbed methane have unsatisfactory dehydration effects. Most of the existin...

Problems solved by technology

[0003] The existing dehydration devices for coalbed methane collection and transportation on the ground have unsatisfactory dehydration effects. Most of the existing dehydration methods use cooling and dehydration methods to cool the moisture in the coalbed methane, so that the moisture in the coalbed methane liquefies and adheres to the gathering and transportation pipelines , most of them do not have the function of automatically knocking and cleaning the water droplets attached to the collection and transportation pipelines during the dehydration process. After a long time of use, a large number of water droplets will adhere to the collection and transportation pipelines, which will affect the subsequent dehydration effect , and it is not convenient to stably filter the dust impurities in coalbed methane before dehydration, which cannot meet the needs of use. Therefore, we propose a high-efficiency dehydration device for ground gathering and transportation of coalbed methane and its use method to solve the above problems
