FIELD: process engineering.
SUBSTANCE: invention relates to filtration, namely, to gas filter intended for cleaning hydrocarbon gases to be used chemical, petrochemical and automotive industries. Proposed filter comprises case 1 with inner heat-insulation wall, inlet branch pipe 21 and discharge branch pipe 22, and divided into three consecutive zones by baffles 2, 3 First zone is that of heating waste gases 26 provided with thermal element 12 with shield 11 secured on baffle 2. Hollow catalytic reactivating filter 27 arranged in second zone has its first end secured on baffle 2 and second end secured on additional hub 14. Third zone accommodates filtration elements 5, 6-9 of catalytic reactivating filter with their ends tightly secured in baffle 3 and case face wall, respectively. Baffles 2, 3 are provided with waste gas passage openings.
EFFECT: simplified design, lower costs and higher efficiency.
