How to deal with spray paint exhaust gas in electronic factories

During the production process, electronic factories often require spray painting to meet the appearance and protection requirements of their products. However, the exhaust gas generated during the painting process contains a large amount of organic compounds and other harmful substances, which have a serious impact on the environment and employee health. In order to solve this problem, electronic factories need to take effective measures for exhaust gas treatment. This article will explore how to deal with spray paint exhaust gas in electronic factories.
1、 The hazards of spray paint exhaust gas
Harm to the environment: Harmful substances such as organic compounds and benzene compounds in paint exhaust gas can pollute the atmospheric environment, causing damage to surrounding vegetation, water bodies, and soil.
Harm to employee health: Prolonged exposure to harmful substances in spray paint exhaust can cause damage to the respiratory, immune, and nervous systems of employees, affecting their physical health.
2、 Methods for treating spray paint exhaust gas in electronic factories
Catalytic combustion method: Catalytic combustion is an efficient waste gas treatment method, which is based on the principle of flameless combustion of organic substances in the waste gas under the action of a catalyst, causing them to decompose into harmless carbon dioxide and water vapor. This method has the advantages of high purification efficiency, energy conservation, and environmental friendliness, and is suitable for the treatment of various types and concentrations of paint exhaust gas.
Activated carbon adsorption method: Activated carbon adsorption is a commonly used method for waste gas treatment, which utilizes the adsorption effect of activated carbon to adsorb harmful substances in waste gas onto the surface of activated carbon. This method has the advantages of simplicity, ease of operation, etc., but it requires regular replacement of activated carbon, which is costly.
Absorption method: Absorption method is a method of absorbing harmful substances in exhaust gas through an absorbent. This method has the advantages of high purification efficiency and wide applicability, but it requires a large amount of absorbent, and the treated waste liquid needs to be further treated, resulting in high costs.
Biological treatment method: Biological treatment method is a method that utilizes the metabolic action of microorganisms to convert harmful substances in exhaust gas into harmless substances. This method has advantages such as environmental friendliness and economy, but requires a specific microbial population and relatively low treatment efficiency.
