Separator filters for cleaning and degassing of water from CBM WELL

摘要

The filter separator for cleaning fluid can be applied, for example, in the extraction of methane from coal seams, in particular for degassing reservoir fluid (water) is pumped (supplied) from the production (CBM) wells, and its purification from mechanical impurities, and in other industries. Filter separator includes a hollow cylindrical body with a tangential inlet pipe and outlet pipe. The lid has an axial passage. Inside the housing are arranged coaxially with the carcass radial channels, and a filter element disposed on the outer side of the frame. Annular cavity formed by the outer surface of the filter element and the inner surface of the housing. There is a hydraulic connection between the annular chamber with a tangential inlet. Average annular cavity is in fluid communication with an outlet. The inner annular cavity in fluid communication with the axial channel. The filter separator is provided with a swirler and a stepped rod, which is coaxially mounted inside the housing. The swirler is formed as a stepped rod embracing a hollow cylindrical sleeve, on the inner surface of which a spiral groove is formed, which imparts inlet to the annular cavity and having an axial channel. From inlet fluid flow moves through the helical groove swirler in the upward direction. The separated liquid from the gas gradually accumulates in the upper part of the body and removed. Degassed liquid stream from mechanical impurities enters the annular space passes through the filter element and is outputted from the housing through the outlet.
