How to choose paint waste gas treatment equipment?

How to choose a paint exhaust gas solution? The editor summarizes the analysis of several types of plans.

1. When the waste gas from spray painting is solved in a site with a low degree of exhaust gas and a large amount of waste gas (drying treatment solution room, spray painting room), the low-temperature plasma disintegration and digestion method can be selected. 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 is low, and the total area is small.

2. Spray paint waste gas solution In normal temperature, relatively low concentration, and relatively small amount of waste gas, the activated carbon filter method can be used to solve the paint waste gas solution. 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. Paint spray exhaust gas solution In the site with high temperature, low flow rate, high paint spray exhaust gas concentration value, and low sediment content, the spray paint exhaust gas solution can be used to solve the catalytic combustion equipment method. 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 solution of paint exhaust gas with relatively low concentration and a lot of wind, the catalytic reaction paint exhaust gas solution can be used. Organic chemical waste gas solves the shortcomings of high cost of work in the traditional activated carbon filter method that manufacturers have changed. The purification treatment has high power, stable work, high safety factor, and it is not easy to replace consumables.

5. The solution of waste gas from spray painting Under the premise of high composition and high temperature of the organic chemical saturated solution, the immediate ignition method can be used to solve the waste gas of spray painting. 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.
