Novel electroplating waste gas treatment apparatus

Abstract

The invention discloses a novel electroplating waste gas treatment apparatus. The novel electroplating waste gas treatment apparatus comprises an electroplating waste gas treatment tower, wherein theleft end of the electroplating waste gas treatment tower is provided with a filter residue collection apparatus, and the left end of the electroplating waste gas treatment tower is provided with a dosing circulating apparatus; the top end of the electroplating waste gas treatment tower is provided with a monitoring apparatus; and the lower end of the filter residue collection apparatus is providedwith a base plate, and the upper end of the base plate is provided with a filter residue collection box. When in use, after the filter residue is precipitated in a waste reservoir, the filter residueflows into the filter residue collection box by virtue of a filter residue gathering oblique block to be gathered and recycled, when the pollutants of the discharged waste gas exceed a set thresholdvalue of a density sensor, an alarming indicator lamp turns on, a chemical-liquid ratio is re-adjusted, whether the apparatus fails or not is detected, and the discharged waste gas is ensured to reachthe standard; and by adopting the novel electroplating waste gas treatment apparatus, the discharged waste gas can be integrally and effectively monitored, the filter residue can be gathered, and theelectroplating waste gas treatment efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a novel electroplating waste gas treatment device. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent Metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. During the electroplating production process, cyanide-containing waste gas and chromium-containing waste gas will be generated, as well as acid mist and alkaline fume may be generated during the pickling process. The generation of these waste gases will not only affect the working environment of the production workshop, but al...

AI Technical Summary

Problems solved by technology

During the electroplating production process, cyanide-containing waste gas and chromium-containing waste gas will be generated, as well as acid mist and alkaline fume may be generated during the pickling process. The generation of these waste gases will not only affect the working environment of the production workshop, but also affect the surrounding areas. The environment will cause air pollution, and the waste residue produced at the same time will also pollute the environment

[0003] The existing electroplating waste gas treatment device has low treatment effect, and even some treated waste gas does not meet the emission standards stipulated by the state. To a certain extent, it will still cause air pollution. Therefore, it is very necessary to monitor the discharged waste gas. Moreover, in the process of treating electroplating waste gas, the enriched filter residue also needs to be treated. If heavy metals are discharged directly, heavy metal pollution will be caused to the water body. If they are collected, smelted, processed and reused, it will not only save resources, but also will not cause solid pollution to the environment. , so a new type of electroplating waste gas treatment device is needed
