The source of the waste gas generated by the electroplating plant is acid mist and alkaline gas which are volatilized when soaked in acid and alkali, and the exhaust gas is highly corrosive and harmful to the human body. At the same time, there are various inorganic waste gases and a small amount of VOC in the production workshop. It is necessary to have qualified, effective, and low-cost exhaust gas treatment equipment. Electroplating plant waste gas treatment tower is preferred by Wuxi Reid Environmental Protection Professional Electroplating Factory Industrial Workshop Dust, Electroplating Chemical Odor odor waste gas treatment.
The electroplating plant generally releases gases such as nitric acid, sulfuric acid, hydrofluoric acid, etc., and uses a pickling tower to pump the gas into the tower for neutralization treatment, and then discharges through the exhaust fan to reach the standard discharge. However, it is important to pay attention to several matters, that is, the composition and concentration of gas, which is an important reason for the discharge of the standard. In addition, the matching fan is selected according to the length of the pipeline, and the fan resistant to acid and alkali corrosion is used. It is recommended to use FRP tower and FRP fan, and the tower and fan have been treated with hydrofluoric acid.
Commonly used electroplating exhaust gases are nitric acid, hydrochloric acid, sulfuric acid, complex acid, chlorine and cyanide waste gas. In the relevant medical manuals, acid and alkali smoldering gases with different inhalation concentrations can cause eye and upper respiratory tract mucosal diseases, tearing or coughing. Such symptoms, when severe, toxic gas is introduced into the lower respiratory tract, leading to pulmonary edema. Cyanide is more toxic and severe, chronic poisoning can cause nausea and sorrow, loss of consciousness, 0.2g can kill people, must be paid attention and vigilance.
Different exhaust gas treatment processes are selected for different gas sources. Acidic gas (SEX) uses alkaline scrubber SCR, alkaline gas (AEX) uses acid scrubber SCR; workshop hot exhaust gas (GEX) enters SCR. It is also possible to add an activated carbon adsorption device.
