Zhejiang Exhaust Gas Absorption Tower Factory shares with you the working principle of several types of waste gas treatment equipment today.
I. Absorption Equipment
VOCs are absorbed by low volatile or non-volatile solvents in the absorption equipment, and then separated by the difference of physical properties between VOCs and absorbents.
II. Adsorption Equipment
When porous solids are used to treat fluid mixtures, a component or some component in the fluid can be absorbed onto the surface and concentrated on it. This phenomenon is called adsorption. When the waste gas is adsorbed, the object of adsorption is gaseous pollutants, gas-solid adsorption. Adsorbed gases are called adsorbates and porous solid substances are called adsorbents.
3. Combustion and Catalytic Purification Equipment of Organic Waste Gas
Combustion is very effective in treating high concentration Voc and odorous compounds. The principle is that these impurities are burned by excessive air. Most of them produce carbon dioxide and water vapor, which can be discharged into the atmosphere. However, when dealing with organic compounds containing chlorine and sulfur, HCl or SO2 in the combustion products need to be further treated after combustion.
4. Treatment Equipment of Low Temperature Plasma for Industrial Organic Waste Gas
Plasma is an ionized gas. Its English name is plasma. It was named by American science Muir in 1927 when he studied the phenomenon of discharge in mercury vapor at low pressure. The plasma consists of a large number of electrons, neutral atoms, excited state atoms, photons and free radicals, but the charge number of electrons and positive ions must be electrically neutral, which is the meaning of "plasma".
