Centralized processing device of phenol-containing waste gas and sulfur-containing waste gas, and processing method

Abstract

The invention discloses a centralized processing device of phenol-containing waste gas and sulfur-containing waste gas, and processing method, and belongs to the field of environmental protection waste gas treatment. The centralized processing device comprises a waste gas inlet (1), a discharge pipe (2), a valve (3), a gas-collecting hood (4), a negative pressure adjustment valve (5), buffer boards (6), an exhaust pump (7), active carbon absorption layers (8), and a chimney (9). According to the processing method, waste gas is delivered upward through the buffer boards (6), after collision and bump with the buffer boards, tar and water are separated, flow automatically into the bottom of the gas-collecting hood (4), and are discharged via the discharge pipe (2); separated gas is subjected to absorption and purification by the active carbon absorption layers (8), and then is discharged into the atmosphere via the chimney (9). The centralized processing device and the processing method are capable of solving emission problems of phenol waste water or sulfur-containing waste gas generated in coal gas production processes, working environment of workers is improved, and pollution on the atmosphere is reduced.

Description

technical field [0001] The invention relates to a waste gas treatment device and a treatment process in the field of environmental protection, in particular to a centralized treatment device and a treatment process for phenol-containing waste gas and sulfur-containing waste gas. Background technique [0002] The coal gasifier is a production equipment that converts coal into a flammable gas-coal gas. The main purpose of the produced gas is to be used as an industrial fuel. [0003] The quench tower of the purification equipment of the two-stage gas generator adopts the method of direct contact with the gas when cooling the gas, and a large amount of phenol water generated flows into the thermal circulation pool by itself from the hot water ditch. Phenolic compounds are volatile and toxic. The direct contact temperature between phenolic water and gas is high, and phenolic compounds volatilize into the air, producing heavy odor, seriously affecting the working environment of e...
