GAS CLEANING DEVICE Russian patent published in 2020 - IPC B01D50/00 

FIELD: gas industry.

SUBSTANCE: invention relates to gas industry and other areas of power machine building, in process cycles of which there is a need to clean gas of mechanical impurities and condensed liquid. Device includes vertical housing (1), inside which coaxially located shell ring (4) and filter element (5) to form external (15) and internal (16) annular channels interconnected in lower part of housing (1). Gas feed branch pipes (2) and purified gas discharge branch pipes (3) are located tangentially in upper part on opposite sides of housing (1). Filtration element (5) is a bearing structure of porous metal with high gas permeability. Collector (7) is connected to lower profiled bottom (6), communicated with liquid and mechanical admixtures discharge branch pipe (26), inside collector (7) there is rod (9) rigidly connected to poppet (10), the lower surface of which and bottom (6) form slotted channel (17), wherein rod (9) and associated poppet (10) are installed with possibility of movement in axial direction relative to profiled bottom (6). In cavity (25) inside collector (7) level sensor (18) is installed. Cavity (25) of collector (7) is connected by bypass line (19) with outlet branch pipe channel (3). Gate valve B3, filter 20 and valve B4 are installed in series in bypass line (19). Gas supply branch pipe (2) is connected to cleaned gas discharge branch pipe (3) by pneumatic main line (24), in which valve B1, pressure difference sensor 23, valve B2 are installed in series.

EFFECT: invention allows improving quality of gas cleaning.
