Methods that can be taken to purify exhaust gas

In real life, there is still a high possibility of generating exhaust gas. Due to the different sources of exhaust gas, there are different precautions in the treatment of exhaust gas. What are the methods we can use to purify exhaust gas in different ways? Now let me share with you briefly, let's take a look together.

1. The principle of dilution diffusion method: Discharging odorous gases into the atmosphere through chimneys or diluting them with odorless air to reduce the concentration of odorous substances and decrease the odor. Scope of application: Suitable for treating organized emissions of odorous gases with medium and low concentrations. Advantages: Low cost and simple equipment. Disadvantage: Easily limited by meteorological conditions, odorous substances still exist.

2. Principle of activated carbon adsorption method: Adsorption method is one of the useful methods for treating low concentration VOCs. It uses adsorbents to adsorb VOCs in the gas, and the purified gas is discharged into the atmosphere. The commonly used adsorbents for organic waste gas treatment equipment include granular activated carbon, zeolite, activated alumina, and silica gel. Due to its low price and good adsorption effect, activated carbon is currently a commonly used adsorbent.

3. Principle of water absorption method: Utilizing the characteristic that certain substances in the odor are easily soluble in water, the odor components come into direct contact with water and dissolve in water to achieve deodorization. Advantages: Simple process, convenient management, low equipment operating costs, secondary pollution, and the need for treatment of the washing solution. Disadvantages: Low purification efficiency, poor treatment effect on thiols, fatty acids, etc.
