Information

According to common sense, any system needs to discharge waste when it is in operation, and the coating production line is no exception! In the process of running the coating production line, there will be four major pollutions. What are the four major sources of pollution? In fact, the four major sources of pollution in the coating production line include waste gas, waste water, waste residue and noise. No matter which industry is spraying, it can't avoid the four major pollution problems. So, what kind of governance should be used in the face of these tough pollution problems? Let Chuangzhi tell you!


1. Noise pollution and treatment

First of all, noise is a pollution that we are relatively easy to perceive. The main source of noise in the coating production line is the fan and the transport device. Therefore, the fan and the transport device that meet the noise requirements must be selected on the production line. material.

2. Waste gas pollution and treatment

Workers in the deep paint production site are very worried about the pollution from the exhaust gas generated during the spraying process. The exhaust gas mainly comes from the exhaust gas from the pretreatment, spray booth, flow chamber and drying furnace. The use of non-organic solvent or low content coating is an effective method to solve the organic solvent, minimize the amount of organic solvent and reduce the organic solvent. Exhaust gas treatment, concentrate the exhaust gas containing high-concentration organic solvent, and discharge it to the atmosphere after dilution; use high-concentration and small-volume organic solution crystal exhaust gas discharged from dry curing oven, using combustion method, catalytic combustion method, adsorption method The treatment is carried out; the low-concentration, high-volume exhaust gas discharged from the spray booth is subjected to activated carbon adsorption, and the activated carbon fiber bee wheel method is used to treat the organic waste gas.

3. Wastewater pollution and treatment

Waste water is more difficult to handle, and the cost and cost of disposal are also large. The waste water is derived from the degreasing, phosphating, passivation wastewater generated by pre-coating treatment, the electrophoretic paint-containing wastewater generated by cathodic electrophoresis, the spray booth of water-based paint and the waste water generated by washing, and the discharge water of the top coat spray booth is periodically discharged. Waste water. Generally, all the wastewater is concentrated in the basement and treated according to the type of sewage. Neutralize, precipitate, filter, and discharge the acid-base wastewater; treat the wastewater containing hexavalent chromium by electrolysis and chemical reduction. The spray booth waste water is treated with a fine coagulant, the paint residue is automatically discharged, the treated waste water is continuously recycled, and the paint residue is burned off or disposed of together with other industrial waste.

 

4. Waste residue pollution and treatment

Waste slag pollution and treatment of waste slag is mainly the treatment of waste water produced by sediment, generally can be dehydrated by plate and frame filter press, transported to the dedicated waste residue storage.

The above is about the "four major pollution sources and treatment methods of coating production line", if you need to know more detailed and detailed coating production line exhaust gas treatment methods, please refer to the following information recommendation, information from 25 years of coating production line manufacturers Chuangzhi coating finishing provides more information about the equipment of the coating production line, welcome to follow us for updated information!
