Waste gas treatment equipment from the industry can be divided into many, different industries need waste gas treatment equipment function is not the same. Among them, spray paint exhaust gas treatment equipment is not particularly used in many occasions, but it is absolutely indispensable to a kind of exhaust gas treatment equipment.


Introduction of paint waste gas treatment equipment


1. Catalytic combustion method can be used for the treatment of paint-spraying waste gas when the temperature is high, the flow rate is small, the concentration of paint-spraying waste gas is high and the impurities are low. The impurities in the exhaust gas should be removed to prevent catalyst poisoning; when the catalyst is used for a long time, the efficiency of exhaust gas treatment will be reduced accordingly; and the cost of waste gas treatment equipment is higher. Features: high efficiency of exhaust gas treatment and small floor area.


2. Under the condition of normal temperature, low concentration and relatively small amount of waste gas, the treatment equipment of spray paint waste gas can be selected by activated carbon adsorption method. Organic solvents in waste gas can be recovered and utilized. Activated carbon regeneration equipment covers a large area, energy consumption, high cost; drying room exhaust gas temperature should be cooled first, spray room exhaust gas more paint fog, paint fog should be removed first. Features: high running cost and high maintenance cost.


3. Paint-spraying waste gas treatment equipment can adopt direct combustion method when the organic solvent content is high and the temperature is high. Disadvantage: There are many preheating energy consumption, high cost; need to consider explosion-proof and other safety measures, heat exchanger, combustion chamber design is more complex. Advantages: high efficiency of paint spray exhaust treatment, general exhaust combustion, that is, to meet the emission standards; paint spray exhaust treatment reliability is high.


4. Spray paint waste gas treatment equipment in the lower degree, more waste gas situation (drying room, spray room), can be used to spray paint waste gas treatment equipment washing absorption method. No explosion, fire and other dangers, good safety. Compared with other methods, the efficiency of paint spraying waste gas treatment is lower; the components of the waste gas in the washing absorption solution need to be treated twice; the selection of paint spraying waste gas purification deodorant should be determined according to the main solvent in the waste gas. Features: paint waste gas treatment equipment has low cost and small footprint. Above is the Suzhou Qiaohui exhaust gas treatment equipment for everybody detailed introduction of the spray paint exhaust gas treatment equipment products, it should be noted that the low concentration, high air volume spray paint exhaust gas treatment equipment, can use photocatalytic spray paint exhaust gas treatment equipment method, purification efficiency, stable operation, high safety factor, no There are defects in replacing consumables.
