The source of waste gas from electroplating plant is acid mist and alkaline gas volatilized during acid-base immersion. The waste gas is highly corrosive and does great harm to human body. At the same time, the production workshop also has inorganic waste gas volatilized by various processes and a small amount of VOC. Qualified waste gas treatment equipment with good effect and low cost shall be provided. The waste gas treatment tower of electroplating plant shall be the first choice for the treatment of dust and electroplating chemical odor waste gas in the industrial workshop of electroplating plant provided by Wuxi Reid environmental protection specialty.
Generally, the electroplating plant will release nitric acid, sulfuric acid, hydrofluoric acid and other gases. The acid pickling tower is used for treatment. The gas is pumped into the tower for neutralization treatment, and then pumped out by the exhaust fan, all of which are discharged up to the standard. However, we must pay attention to several matters, that is, the gas composition and concentration are an important reason for whether the emission can meet the standard. In addition, the matching fan shall be selected according to the length of the pipeline, and the fan resistant to acid and alkali corrosion shall be selected. It is recommended to select FRP tower and FRP fan, and the tower and fan have been treated with hydrofluoric acid resistance.
The common electroplating waste gas is mostly nitric acid, hydrochloric acid, sulfuric acid, complex acid, chlorine and cyanide waste gas. In the relevant medical manuals, inhalation of acid-base gas with different concentrations will cause eye and upper respiratory tract mucosal diseases, tears or cough. In serious cases, the toxic gas will be introduced into the lower respiratory tract, resulting in pulmonary edema. Cyanide toxicity is more severe. Chronic poisoning can cause nausea, salivation and loss of consciousness. 0.2g can kill people. Attention and vigilance must be paid to it.
Different waste gas treatment processes are selected for different gas sources. Alkaline scrubber SCR is selected for acid gas (sex) and acidic scrubber SCR is selected for alkaline gas (AEX); Workshop hot exhaust ventilation (Gex) is introduced into SCR, and activated carbon adsorption device can also be added.
