GAS CLEANING REACTOR Russian patent published in 1999 - IPC

FIELD: cleaning emissions containing toxic components. SUBSTANCE: gas cleaning reactor includes heat-insulated housing with contaminated and cleaned gas chambers between which cassettes with inlet and outlet cavities alternating in height are located. Cassettes are made in form of row of perforated shelves with catalyst and/or active filler located on them; second row of shelves mounted additionally crosses first row at acute angle, thus forming closed volumes. Shelves are parallel in each row. After crossing of shelves in way of motion of gas, thickness of layer of catalyst and/or active filler is determined according to the following formula B_i= B_i-Ix(I+P), where B_i is the quantity sought for, mm; B_i-I is thickness of previous layer, mm; P = (C_i-C_i+I)/C_i is degree of cleaning of gas by means of layer of thickness being determined and C_i i C_i+I are concentrations of toxic agents contained in gas before and after layer being determined, mg/cu.m. Proposed gas cleaning reactor makes it possible to clean gas to 99.9% with no change in overall dimensions. EFFECT: simplified construction; facilitated procedure; enhanced operational reliability during entire service life. 3 cl, 2 dwg
