Abstract

The invention relates to a chromium fog recovery system provided with a chromium electroplating tank. The system comprises the chromium electroplating tank, a fan, a chromium fog recovery device, a chromium fog recovery tower, a gas purification chamber, a recovery tank and a pure water tank, wherein a gas collecting outlet is formed in one side surface of a position 10-15 cm below an opening of the chromium electroplating tank; the chromium fog recovery device, the chromium fog recovery tower and the gas purification chamber are provided with filter layers respectively; the chromium electroplating tank, the fan, the chromium fog recovery device, the chromium fog recovery tower, the gas purification chamber and the recovery tank form a recovery and utilization circulating system through a gas collecting pipeline, a gas delivery pipeline, a recovery pipeline, a feedback pipeline and a reuse pipeline. With the adoption of the system, waste gas is completely recovered, and chromium fog leakage is avoided; through special filtration and neutralization, emptying is realized after purification, recovery is complete, the environment is not polluted, and a pollution-free and environment-friendly chromium electroplating technology without waste gas exhausting is created. Chromium electroplating solution evaporation is reduced in the technological process, the treatment efficiency is high, a chromium-containing solution is recycled, and the operation cost is reduced; the problem that chromium electroplating waste gas pollutes the environment is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of electroplating waste gas treatment, in particular to a chrome mist recovery system from a chrome plating tank. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of metal or other material parts using the principle of electrolysis. Through electroplating, a metal film can be attached to the surface of metal or other material parts. To prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance the appearance. Therefore, the electroplating process is widely used in the production process of machinery, hardware and electrical appliances. Electroplating is an indispensable industry for the development of the national economy. The pollution caused by electroplating to the environment cannot be ignored, and the treatment of the three wastes of electroplating is...
