Abstract

The invention discloses a light coal tar odor removal system which comprises an odor removal system body; the odor removal system body comprises a light coal tar buffer tank, a booster pump, a first-stage reactor and a second-stage reactor, and the first-stage reactor comprises a first fiber membrane mass transfer reactor and a first phase separation tank; the second-stage reactor comprises a second fibrous membrane mass transfer reactor and a second phase separation tank, the light coal tar enters the light coal tar buffer tank, the booster pump conveys the light coal tar and a stream of leanalkali liquor conveyed by the lean alkali liquor pump to the first-stage reactor for primary sweetening, and then the light coal tar enters the first phase separation tank for settling separation; the separated light coal tar is sent out from the top of the first phase separation tank, filtered by a fine filter and then conveyed into the second-stage reactor together with another stream of poor alkali liquor conveyed by a poor alkali liquor pump for second-stage sweetening. According to the invention, the problem that the light coal tar produces large peculiar smell during storage, loading and transportation is solved.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry environmental protection, and in particular relates to a light coal tar deodorization system. Background technique [0002] In the process of sustained development and scale expansion of the country's economy and industry, coal chemical projects continue to increase, and the resulting coal tar has also become a wide range of chemical raw materials. How to improve the transfer, transportation, transformation and application of coal tar while protecting the environment has put forward a change request for the processing of coal tar. [0003] Due to its strong volatility and high sulfur content, light coal tar has a strong odor and has a significant impact on the environment during storage and transportation. How to reduce the peculiar smell has become a difficult problem that must be overcome. Contents of the invention [0004] In view of this, the object of the present invention ...
