Electroplating waste gas comprehensive treatment device and process

Abstract

The invention relates to an electroplating waste gas comprehensive treatment device and an electroplating waste gas comprehensive treatment process. The electroplating waste gas comprehensive treatment device comprises a plating tank waste gas treatment system and an organic waste gas treatment system; the electroplating waste gas comprehensive treatment process comprises the following steps of: feeding a waste gas generated by each plating tank, a waste gas generated in a paint spraying process and organic waste gas generated in an electrophoresis drying process to an acid mist treatment tower or a purifying treatment tower for absorbing and treating after respective pre-treatment; spraying the waste gases to a spraying device in a primary spraying treatment box for spraying and atomizing; moving down the atomized waste gases along a ventilating tube under the pushing of continuously fed-in gases, wherein the ventilating tube is under an absorption liquid level; separating the gases into fine gas bubbles by virtue of gas pores; spraying and treating the gases treated by the absorption liquid by a secondary spraying device and a tertiary spraying device when the gases overflow out of the liquid level and are exhausted in an exhaustion port direction; and finally exhausting the treated gases from a gas exhaustion barrel. The electroplating waste gas comprehensive treatment device and the electroplating waste gas comprehensive treatment process disclosed by the invention can be used for comprehensively treating various waste gases according to the complex and various characteristics of waste gases in the electroplating enterprises, so that the treatment effect and the treatment efficiency are greatly improved, and therefore, an important path is provided for the environment-friendly work of the electroplating enterprises.

Description

technical field [0001] The invention relates to a waste gas comprehensive treatment device and process, belonging to the technical field of environmental protection. Background technique [0002] Electroplating enterprises mainly focus on galvanizing and decorative chrome plating, with a small amount of jewelry electroplating, electrophoretic paint, and spray paint. According to the electroplating process of each enterprise and the raw materials used, the main types of waste gas generated are: acid-base mist, chromic acid mist, hydrogen cyanide, and organic waste gas. The current exhaust gas operation facilities of the enterprises in the existing park mainly adopt self-operation control, manual dosing and artificial control of dosing time. It is very likely that the waste gas will be caused by untimely dosing, too much or too little non-compliance issues. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior ...
