A spray tower, also known as a spray scrubber, is an absorption tower containing packing or plates and equipped with nozzles. Liquid enters from the top of the tower and is sprayed into a mist or droplet form through the nozzles. Gas enters from the bottom of the tower and comes into close contact with the mist or droplets for mass transfer, allowing the easily soluble components in the gas to be absorbed. It features a simple structure, is not easily blocked, has low resistance, and is easy to operate and maintain.

Activated carbon adsorption equipment is an environmental protection device that uses porous solid adsorbents to treat organic waste gas. It utilizes the large surface area and abundant micropores of activated carbon to adsorb organic substances on the surface of the adsorbent, thereby achieving the purpose of purifying waste gas.

The automatic dosing device is an automatic dosing equipment, which can be divided into integrated automatic dosing device, circulating water automatic dosing device, boiler automatic dosing device, phosphate automatic dosing device, etc. The specifications of each dosing device are not the same. This should be noted in the selection, different industry needs should choose the corresponding equipment. The dosing device is a complete set of equipment with dosing, stirring, conveying liquid and automatic control. It is used for the circulating water system that needs to add buffer, scale inhibitor and bactericide to accurately add and measure the water quality treatment agent. In the process of water supply and drainage treatment, various chemicals are often added as scale inhibition, sterilization and algae control, coagulation and flocculation to achieve the purpose of water purification.
