DEVICE FOR TWO-STAGE CLEANING OF HIGH PRESSURE NATURAL GAS PARTICLES

摘要

The utility model relates to gas supply, in particular to devices for two-stage purification of natural gas from large and small solid particles. The technical task of this solution is to prevent the deposition of solid particles in the lower part of the gap between the cylindrical filtering elements of preliminary and fine cleaning and preservation of the initial throughput of the device. A device for two-stage cleaning of solid particles of high-pressure natural gas contains a vertically mounted cylindrical body with inlet and outlet nozzles in its lower part and a flange in the upper part of the body on which the cover is hermetically fixed. Inside the housing there is a cup connected to the outlet pipe, and cylindrical filter elements - a pre-filter element from a metal mesh and a fine filter element located along the inner surface of the pre-filter element with the formation of a gap between them. The filter elements are hermetically connected in the lower part to the glass, and in the upper part with an additional cover connected to the glass. The fine filter element is made of synthetic mesh laid in layers and sealed. The first layers in the direction of the gas flow are made with a mesh size exceeding the mesh size of the preliminary filter element. The number of these layers is selected from the condition that their total thickness exceeds the mesh size of the pre-filter element. The subsequent layers of the fine filter element have a mesh size smaller than the cell size of the preliminary filter element. The mesh size of these layers decreases gradually and the last layer has a minimum mesh size. 3 s.p. f-ly, 2 ill.
