DEVICE FOR FILTRATION OF GASEOUS EXPLOSION PRODUCTS Russian patent published in 2024 - IPC B01D46/62 B01D46/12 

FIELD: gas industry.

SUBSTANCE: invention relates to filtration of gases and relates, in particular, to devices for purifying gaseous explosion products (GEP) when they are released from special-purpose chambers (SPC). Device for filtration of gaseous explosion products contains a power housing attached to the GEP release channel, inlet and outlet channels, a filtering system containing coarse and fine filters, which are interconnected through an air cavity. Coarse filter is a granular adsorbent material with high thermal and chemical resistance, filled into the cavity of the power housing between the inlet and outlet grids placed in it and pressed to inlet channel by clamping element with axial holes closed by outlet screen. Fine filter is a sealed housing with a filter plate and has inlet and outlet nozzles, wherein the end of the outlet nozzle is also an outlet channel of the device. Power housing is made detachable and consists of a central part tightly closed with an inner and an outer cover. Fine filter housing is placed in a cavity filled with adsorbent material, and ends of nozzles are detachably connected to the clamping element and to the outer cover; at that, the connection unit of the outlet nozzle end is made tight.

EFFECT: providing reliable operation of the device when releasing gaseous explosion products containing aerosols of toxic materials from SPC, while improving operating characteristics.
