Abstract

The invention relates to a thermal storage oxidation incinerator for tail gas generated by phthalic anhydride. The thermal storage oxidation incinerator comprises a flue gas pyrolysis chamber and a spray scrubber, wherein the air inlet of the flue gas pyrolysis chamber communicates with the air outlet of an exhaust gas pipeline, and the air outlet of the flue gas pyrolysis chamber communicates with the air inlet of a waste heat boiler; the air inlet of the spray scrubber communicates with the air outlet of the waste heat boiler, the air outlet of the spray scrubber communicates with one end ofan exhaust pipe, and the other end of the exhaust pipe is accessed to the atmosphere. The purpose of the invention is to provide the thermal storage oxidation incinerator for the tail gas generated by the phthalic anhydride with more sufficient thermal oxidation and accurate control of pyrolysis time.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a thermal storage oxidation incineration device for tail gas produced from phthalic anhydride. Background technique [0002] Phthalic anhydride is a cyclic anhydride formed by intramolecular dehydration of phthalic acid. Phthalic anhydride is a white solid and is an important raw material in chemical industry, especially for the manufacture of plasticizers. The tail gas of phthalic anhydride produced by naphthalene method contains a small amount of organic compounds such as phthalic anhydride, maleic anhydride, naphthoquinone benzoate and trace amounts of unconverted naphthalene and CO, SO2, if discharged directly, it will cause serious damage to the environment. Therefore, it is necessary to design a device to treat the tail gas produced by phthalic anhydride. Contents of the invention [0003] Therefore, the technical problem to be solved by the pres...
