COMPLEX WITH FILTER FOR DRY CLEANING OF EXPLOSIVE GAS MIXTURES Russian patent published in 2017 - IPC A62C4/02 A62C2/06 A62C3/06 

FIELD: chemistry.

SUBSTANCE: complex filter for dry cleaning of explosive gas mixtures comprises a bag filter 1 connected to the input flue 2, on which the inlet shut-off valve 3 and the pipe 18 with the shutoff valve 19 for connection to the atmosphere are mounted. The exhauster 5, the output shut-off valve 6, the pipe 20 with the shutoff valve 21 for connection to the atmosphere and to the gas sampler 22 are mounted on the outlet flue 4. Before the filter 1 downstream an explosion-localizing gas chamber 7 connected to the input flue 2 and to the filter 1 through the normally open self-closing in case of explosion valves 8 and 10 respectively. The explosion-localizing chamber 7 is provided with the igniter 11, the anti-explosion safety valve 12, the pipe 13 with the gate 14 for connecting to the atmosphere and to the explosion pressure sensor relay 15, which is electrically connected through the gas cleaning control system to the electric drives of the input shut-off valve 3, the output shut-off valve 6 and the exhauster 5. The filter housing 1 is made airtight. The explosion-localizing chamber 7 and the filter 1 are provided with airtight dust dumpers.

EFFECT: location of the explosion-localizing chamber prevents the explosion wave spread and the filter elements destruction while cleaning explosive gas mixtures.
