Introduction of exhaust gas emission process in electroplating process:
The electrical treatment program considers the treatment with a packed spray tower. The spray tower uses the principle of absorption to achieve the purpose of treating exhaust gas. The absorption treatment is a process of treating a gas mixture with a liquid absorbent to remove one or more of the gases. Physical processes in which certain gases dissolve in solution occur during this process, which is physical absorption. There is also a chemical reaction between chemicals in the gas and liquid, which is chemical absorption. Absorption is often used for the treatment and recovery of gaseous contaminants. The absorption method is characterized in that it can absorb harmful gases and remove dust in the exhaust gas. The absorption method is divided into physical absorption and chemical absorption. Physical absorption is a purely physical dissolution process when a liquid is used to absorb harmful gases and vapors. It is suitable for harmful gases and vapors with relatively high solubility in water, and generally has low absorption efficiency. Chemical absorption is accompanied by a distinct chemical reaction during the absorption process, not a pure dissolution process. The chemical absorption efficiency is high, and it is a harmful gas treatment method which is currently applied more. The method used in this process is to treat the exhaust gas by physical and chemical methods.
