Plating waste gas treatment device

Abstract

The invention discloses a plating waste gas treatment device used for evaporation concentration of a solid-containing aqueous solution in the industries of plating, chemistry, chemical engineering and the like. The device comprises an air suction cover arranged on a plating tank, wherein the air suction cover is communicated with a spray compartment through an air suction pipe; the spray compartment is communicated with a gas-liquid separation tower, and a plurality of spray heads are arranged in the spray compartment; the bottom of the gas-liquid separation tower is provided with a reclaiming liquid collecting compartment communicated with the spray compartment; a collision cap is arranged above the reclaiming liquid collecting compartment; a filler layer is arranged above the collision cap; the upper part of the filler layer is connected with an air outlet pipe; the air outlet pipe is connected with a fan, and the bottom of the reclaiming liquid collecting compartment is connected with a reflux pipe; the reflux pipe is communicated with a temperature controlled evaporation tank; and the spray heads are communicated with a temperature controlled evaporation device through circulating cooling pumps. The plating waste gas treatment device has the advantages of small volume, convenience for maintenance, remarkable energy conservation, controllable concentration and long service life.

Description

technical field [0001] The invention relates to electroplating equipment, in particular to an electroplating waste gas treatment device. Background technique [0002] The electroplating industry is an important processing industry in my country. At present, galvanizing, chrome plating, nickel plating and copper plating are mainly used, and they are concentrated in the industrial fields of machine manufacturing, light industry, electronics, aerospace and instrumentation. Electroplating processing is usually the The object to be plated is placed in the electrolytic tank containing the corresponding chemical electrolyte, and the surface of the object to be plated is energized to form an electroplating layer. During this process, a large amount of electroplating waste gas containing heavy metals will be generated. If it is directly discharged without any treatment, It will cause serious pollution to the environment. In order to meet today's increasingly stringent environmental pro...

Problems solved by technology

[0003] In recent years, the treatment of electroplating waste gas is generally to concentrate and utilize the heavy metals in the electroplating waste gas, so that the heavy metals in the electroplating waste gas become valuable products. However, the existing electroplating waste gas treatment devices generally have complex structures and large volumes. , the concentration effect is not good, the service life is short, and it is not suitable for widespread use
