FRP spray towers are common environmental protection equipment, mainly used for absorbing and treating harmful gases in industrial production processes. Their working principle is based on liquid-phase absorption technology. By bringing waste gas into contact with liquid absorbents, harmful substances in it dissolve in the absorbents to purify the waste gas. This article will introduce the working principle of FRP spray towers.

Structure and Components of Spray Towers

FRP spray towers usually consist of an air inlet, an air outlet, a packing layer, and a spray system, etc. Among them, the packing layer is an important component, which has a large surface area and porosity, can increase the gas-liquid contact area, and thereby improve the absorption effect; while the spray system is used to spray liquid absorbents into the tower and evenly distribute them on the packing layer.

Working Principle of FRP Spray Towers

The working principle of FRP spray towers is based on liquid-phase absorption technology, and the main process is as follows:

(1) Waste gas enters the tower body: The waste gas enters the bottom of the spray tower through the exhaust pipe.

(2) Spray of liquid absorbents: Liquid absorbents are evenly sprayed into the tower through the spray system to fully contact the waste gas.

(3) Chemical reaction: Harmful substances in the waste gas undergo a chemical reaction with the liquid absorbents and dissolve in the absorbents.

(4) Discharge of purified gas: The treated gas is discharged from the top of the tower to meet environmental protection requirements.

The Role of the Packing Layer

The packing layer is an important component in FRP spray towers, and its main roles are:

(1) Increase the surface area: The special structure of the packing layer can increase the gas-liquid contact area and improve the absorption effect.

(2) Enhance the density: By filling the packing, a greater humidity can be generated in the tower for the waste gas, enhancing the density and facilitating the interaction between the absorbents and the waste gas.

(3) Improve efficiency: The design of the packing layer can make the gas flow and liquid flow move alternately, increase the contact time and frequency of the liquid film and gas flow, and improve the absorption efficiency.

The Role of the Spray System

The spray system is an important component in FRP spray towers, and its main roles are:

(1) Spray absorbents: Spray liquid absorbents evenly into the tower through the spray system to fully contact the waste gas.

(2) Even distribution: The spray system can evenly distribute the absorbents on the packing layer, increase the gas-liquid contact area, and improve the absorption effect.

(3) Adjust the flow rate: The spray system can adjust the flow rate and spray speed of the absorbents as needed to achieve the best absorption effect.

In conclusion, FRP spray towers are an environmental protection equipment that uses liquid-phase absorption technology to treat harmful gases. Their working principle is based on the chemical reaction between waste gas and liquid absorbents. The purification of waste gas is achieved through the packing layer and the spray system. The packing layer can increase the gas-liquid contact area and improve the absorption efficiency; the spray system can evenly spray liquid absorbents into the tower to fully contact the waste gas and adjust the flow rate to achieve the best absorption effect.
