Overview: Spray tower absorption is a traditional method for organic waste gas treatment. It is a device that purifies various toxic and harmful waste gases by selecting and preparing different absorbents based on the characteristics of VOCs in different waste gases, and using a spray packing treatment method. It belongs to a two-phase reverse differential contact filling absorption tower. The packing inside the tower is the basic component for gas-liquid two-phase contact, which can provide a sufficiently large surface area without causing excessive resistance to gas flow. Absorbent is the main medium for treating exhaust gas, and its properties and concentration are selected according to the properties of different exhaust gases. The consumption per unit gas treated is determined by calculating the ratio of the molar flow rate of absorbent to inert gas. It is generally composed of tower body, spray system, packing system, water mist removal system, absorbent storage system, etc.

Overview: Absorption is the process of using liquid absorbents to treat gas mixtures to remove one or more gases. During this process, there will be a physical effect of certain gases dissolving in the solution, which is physical absorption. Chemical reactions also occur between chemical substances in gas-liquid mixtures, which is known as chemical absorption. Absorption is often used for the treatment and recovery of gaseous pollutants, such as the absorption of sulfur dioxide in flue gas with lime lotion to generate gypsum; Absorb nitrogen oxides in the tail gas of nitric acid plants with alkaline solution or dilute nitric acid, and recover and reuse them; Also, alkaline solutions such as sodium carbonate can be used to absorb hydrogen sulfide. Absorption is also widely used in the pretreatment of organic waste gases, such as dust removal, oil mist removal, and removal of water-soluble components, in preparation for further purification. Absorption method is one of the most important methods for separating and purifying gas mixtures, and is widely used in the treatment of gaseous pollutants such as SO2 NOx、 Fluoride, hydrogen chloride and other waste gases
