DEVICE FOR FILTRATING GASEOUS EXPLOSION PRODUCTS Russian patent published in 2017 - IPC B01D46/00 B01D46/10 

FIELD: machine engineering.

SUBSTANCE: invention relates to devices for cleaning gaseous explosion products (GEP) when they are discharged from the chamber. The device for the filtrating gaseous explosion products (GEP) contains a propulsion body, attached in the chamber to the channel for discharging GEP, an input, an output and a filtering system containing coarse and fine filters installed in the mentioned sequence from the input. Orifice holes are made on the side of the input in the propulsion body. The coarse filter is a granular adsorbent material filled in the cavity of the propulsion body between the input and output grids placed in it and pressed to the input on the side of the output grid by a screw stopper with the orifice holes. The fine filter is installed in the discharge channel and is a sealed housing with a filter plate installed with an air gap in the channel and having an inlet and outlet fittings, the ends of each of which are fixed in sleeves sealed by a series of O-rings in the mentioned channel. Between the input to the discharge channel and the coarse filter there is an adapter with a through hole.

EFFECT: ensuring increase in efficiency of the filtration device under the conditions of explosion and cleaning of gaseous explosion products containing aerosols of toxic materials when they are discharged from the chamber.
