Industrial exhaust gas treatment is an important part of environmental protection work, aiming to reduce harmful gas emissions, protect the atmospheric environment, and promote sustainable development. To effectively address the issue of industrial exhaust gas, we need to adopt a series of scientific, reasonable, and efficient solutions. This article will detail several main methods for industrial exhaust gas treatment, including physical methods, chemical methods, biological methods, and new technologies, in order to provide a useful reference for solving the problem of industrial exhaust gas.
The composition of pollutants in spray painting exhaust gas is determined by the raw and auxiliary materials used in the process. Paint consists of film-forming substances, pigments, auxiliaries, solvents, and diluents. The first three are generally solids and do not volatilize. The main volatile components are solvents and diluents, the main components of which are aromatic compounds and non-methane total hydrocarbons volatile organic waste gas. Therefore, particles, non-methane total hydrocarbons, and aromatic compounds become harmful substances that need to be treated in spray painting exhaust gas treatment.
So, the problems that spray painting enterprises will face are: from which aspects should spray painting exhaust gas be addressed? What kind of exhaust gas treatment equipment is effective? First, spray painting exhaust gas can be treated by a combination of solutions from several aspects: replacement of raw materials, upgrading of production lines, anti-overflow and closed management during the production process, and purification of exhaust gas treatment equipment at the end. Here, Mublue Environmental Protection recommends the RTO exhaust gas incineration furnace equipment to solve the problems of end-of-pipe treatment.
Operating principle of RTO exhaust gas incineration furnace equipment:
After the organic waste gas is preheated and heated in the preheating chamber, it enters the combustion chamber for high-temperature incineration (heated to 800℃), causing the organic matter to oxidize into carbon dioxide and water. After being stored in another heat storage chamber, it is discharged. The stored heat is used to preheat the newly entering organic waste gas, and the furnace temperature is maintained stable by periodically changing the flow direction.
Advantages of RTO exhaust gas incineration furnace equipment:
Insensitive to a small amount of dust and solid particles in the exhaust gas, more precise treatment of exhaust gas molecules; highest thermal efficiency among all thermal combustion purification methods (>95%); self-heating operation can be achieved without adding auxiliary fuel under suitable exhaust gas concentration conditions; small pressure loss of the entire device, long service life of the device.
(1) The paint booth should not contain any parts or paint cans, etc., as these items will accumulate dirt and ultimately contaminate the vehicle to be painted.
(2) After each painting operation, the floor and walls of the paint booth should be cleaned, and items such as the coverings used to cover the vehicle body should be cleaned up.
(3) The vehicle to be painted is usually the largest source of pollution in the paint booth. Wheels, bumpers, and engine compartments accumulate a lot of contaminants. Thorough vehicle cleaning can reduce the impact of these contaminants on the painting operation.
(4) The work clothes worn by the painting personnel are also an important source of pollution. Specialized work clothes should be worn when spraying the paint surface. Inside, lint-free work clothes should be worn, along with rubber gloves, a face shield, and a respirator. This attire should be maintained when spraying each coat of paint.
(5) Spray guns and other spraying equipment must be kept clean. The spray gun should be cleaned immediately after each spraying operation to prevent the paint inside from drying. Dried paint will clump together, and if these clumps are ejected during spraying, they will cause defects on the paint surface.
