Abstract

The invention provides a treatment method and a treatment device of chemical exhaust, and relates to the field of chemical exhaust treatment. The treatment method of the chemical exhaust comprises thefollowing steps: S1, introducing the chemical exhaust into an empty tower and carrying out primary spray washing to obtain primary treatment gas; secondly, enabling the primary treatment gas to passthrough a tray and carrying out secondary spray washing to obtain secondary treatment gas; S3, defogging the secondary treatment gas to obtain purified gas and thus finishing the treatment of the chemical exhaust. By utilizing the treatment method, the technical problem that an existing chemical exhaust treatment method can not meet the environmental protection requirements is solved, and the effects of improving purification effect and enabling the emitted gas to meet the environmental protection emission standard are realized.

Description

technical field [0001] The invention relates to the field of chemical tail gas treatment, in particular to a processing method and device for chemical tail gas. Background technique [0002] In the chemical industry, the treatment of exhaust gas has always been a persistent problem for enterprises. With the continuous improvement of environmental protection standards and the continuous strengthening of environmental protection awareness, the requirements for chemical companies to deal with exhaust gas are getting higher and higher. [0003] At present, in order to meet the zero-emission standard, chemical companies need to use very sophisticated and complex equipment to treat the exhaust gas. The investment in this equipment is huge, and companies are often unable to afford it. Especially when the chemical tail gas contains both dust and ammonia and other restricted emissions, the current methods and devices can no longer meet the requirements of environmental protection. ...
