How to deal with exhaust gas from UV curing machine

The main components of UV curing machine exhaust gas include volatile organic compounds (VOCs), water-carrying agents (such as toluene, cyclohexane, etc.) and a small amount of solid particles. If these waste gases are directly discharged without treatment, they will cause harm to the environment and human health. The following are some common UV curing machine exhaust gas treatment methods: ●  Catalytic combustion method: This is a simple exhaust gas treatment method that converts organic matter in the exhaust gas into carbon dioxide and water through combustion. However, this method does not consider the recycling and reuse of the water-carrying agent in the exhaust gas. It is a method that is ineffective, wastes money, increases production costs for environmental protection, and reduces the competitiveness of enterprises.

●  Activated carbon adsorption method: Using the adsorption effect of activated carbon, the organic matter and water-carrying agent in the exhaust gas are adsorbed on the surface of activated carbon. This method has complex equipment, difficult operation, high operating costs, and serious waste of resources.

●  Cooling water spray system + organic solvent cold absorption-thermal desorption system: This is a fully closed exhaust gas circulation system, including a cooling water spray system, organic solvent cold absorption-thermal desorption system and recycling exhaust gas turnover system. can realize the recycling of aqueous agents in exhaust gas, while completely eradicating VOCs as a source of air pollution.

When selecting a UV curing machine exhaust gas treatment method, factors such as the composition, concentration, emission standards, and treatment costs of the exhaust gas need to be considered. At the same time, in order to ensure the effectiveness and safety of exhaust gas treatment, it is recommended to choose professional exhaust gas treatment equipment and service providers, and conduct reasonable design and installation according to the actual situation.
