Description

Technical Field

[0001] This utility model relates to the field of underground safety production technology in coal mines, and in particular to a gas-liquid separation device for coalbed methane wells. Background Technology

[0002] Coalbed methane wells are one of the important energy sources in underground coal mines, but during their extraction, the problem of gas and water mixing is often encountered. This mixture not only affects the quality of the coalbed methane but can also lead to a series of safety hazards such as equipment corrosion and pipeline blockage, impacting safe production in underground coal mines. Therefore, effectively separating gas and water to ensure the purity and safety of the gas has always been a technical challenge in coalbed methane extraction.

[0003] Existing coalbed methane gas-liquid separation technologies mostly employ single separation devices or simple mechanical structures for preliminary separation. While these can remove some moisture to a certain extent, they cannot completely eliminate moisture from the gas, and their separation efficiency is low, making it difficult to meet the requirements for long-term stable coalbed methane transportation. Furthermore, due to the complexity of the equipment structure and low operating efficiency, existing technologies have limitations in improving coalbed methane transportation quality and ensuring equipment safety. Therefore, this utility model provides a coalbed methane well gas-liquid separation device. Utility Model Content

[0027] The desiccant box 3 is equipped with a first filter media box 20 and a second filter media box 22, which are arranged vertically.

After the gas containing water enters the drain valve 2, the density of the gas is higher than that of the water.

Then the water flows into the receiving box 19 through the air inlet pipe 8 of the drain valve 2 for centralized treatment. The gas enters the drainage pump 1 through air inlet pipe 7, and then enters the moisture interception box 3 through the air outlet pipe 4 and the round-to-square pipe 5. The gas is thoroughly dehydrated by the silica gel in the second filter box 22 and the first filter box 20. The dehydrated gas is then transported to the designated area through the air outlet pipe 6.
