Selection method of paint waste gas treatment equipment

Today, Xiaobian brings you the selection method of spray paint exhaust gas treatment equipment, hoping to help you.

1. For the treatment of waste gas from spray painting, in sites with low degree of waste gas and large amount of waste gas (drying treatment solution room, painting room), low-temperature plasma disintegration and digestion method can be used. There is no risk of on-site engineering blasting work, safety accidents, etc., and the safety performance is good.

Compared with other methods, the waste gas management scheme of spray painting has lower power; the effective components of waste gas in the cleaning and digestion solution need to be treated twice; the selection of aldehyde scavenger for waste gas purification treatment by painting should be determined according to the key organic solution in the waste gas. Features: The cost of spraying organic chemical waste gas treatment is low, and the total area is small. 

2. Spray paint waste gas treatment In normal temperature, relatively low concentration, and relatively small amount of waste gas, the activated carbon filter method for paint waste gas treatment can be selected. There is often organic saturated solution in the exhaust gas, which can be comprehensively utilized and used. When the activated carbon is remodeled, the mechanical equipment covers a large area, and the energy consumption is high and the cost is high; when the temperature of the exhaust gas in the drying treatment room is high, it must be cooled first. fog. Features: High cost of work and high maintenance cost.

3. Painting waste gas treatment In the site with high temperature, low flow rate, high concentration value of painting waste gas, and less sediment, the method of catalytic combustion equipment for painting waste gas treatment can be selected. The sediment in the exhaust gas should be removed to avoid catalyst poisoning; when the metal sulfide is used for a long time, the power of the exhaust gas management scheme should be reduced; the cost of exhaust gas rectification machinery and equipment is high. Features: The exhaust gas management solution has high power, and the mechanical equipment occupies a small area.

4. For the treatment of paint exhaust gas with relatively low concentration and a lot of wind, the catalytic reaction paint exhaust gas treatment method can be selected. The organic chemical waste gas treatment manufacturer has changed the shortcomings of the traditional activated carbon filter method of high work cost, high purification treatment power, stable work, high safety factor, and it is not easy to replace consumables.

5. Spray paint exhaust gas treatment Under the premise of high organic chemical saturated solution composition and high temperature, the immediate ignition method of spray paint exhaust gas treatment can be used. Low point: there is a lot of heating energy consumption and high consumption; safety management measures such as explosion-proof type need to be fully considered, and the design of heat exchangers and combustion chambers of automobile engines is messy. Advantages: The paint exhaust gas management scheme has high power. Generally, after the exhaust gas is ignited, it will reach the discharge standard; the paint exhaust gas management scheme has high reliability.
