The following is a detailed introduction to the waste gas deodorization system:
1.System Overview
The waste gas deodorization system converts the malodorous components in the waste gas into harmless substances through a series of technical means, such as chemical reactions, physical adsorption, biodegradation, etc., thereby reducing pollution to the environment and harm to the human body.

The system is widely used in various places where malodorous gases need to be treated, such as chemical plants, garbage treatment plants, sewage treatment plants, etc.
Ⅱ.Working Principle
The working principle of the waste gas deodorization system is mainly based on the following technologies:

Activated carbon adsorption method:
Principle: Use the porous structure and huge specific surface area of activated carbon to adsorb harmful substances in the waste gas. The micropores, transition pores and macropores of activated carbon give it excellent adsorption performance.
Features: Small investment, high initial removal rate, but activated carbon needs to be replaced after long-term operation, the operating cost is relatively high, and secondary pollution may occur.
Catalytic combustion method and catalytic oxidation method:
Principle: Under the action of high temperature and catalyst, the harmful substances in the exhaust gas are completely oxidized and decomposed, and converted into harmless carbon dioxide and water.
Features: High treatment efficiency, suitable for high-concentration exhaust gas treatment, but high requirements for organic exhaust gas components and large energy consumption.
Biodegradation method:
Principle: Through the metabolism of microorganisms, the organic matter in the exhaust gas is decomposed into harmless substances.
Features: Low treatment cost and wide application range, but the treatment efficiency is greatly affected by environmental factors such as temperature and humidity.
Washing method:
Principle: Taking advantage of the characteristics that some substances in the exhaust gas are easily soluble in water, the exhaust gas is contacted with water through a spray device to dissolve the harmful substances in the water.
Features: The treatment effect is stable, but secondary pollutants such as wastewater may be produced.
Ⅲ.System composition
The exhaust gas deodorization system usually consists of the following parts:

Pretreatment device: Pre-treatment of the exhaust gas such as dust removal and cooling to improve the subsequent treatment effect.
Main treatment device: Select appropriate treatment equipment according to the waste gas composition and treatment requirements, such as activated carbon adsorption tower, catalytic combustion device, biofilter, etc.
Post-treatment device: Further purify the treated waste gas to ensure that it meets the emission standards.
Pipeline system: Responsible for transporting waste gas from the source to the treatment device, and discharging the treated waste gas into the atmosphere.
Control system: Automatically control the entire system to ensure stable operation of the equipment and waste gas treatment effect.
Ⅳ.Application field
Waste gas deodorization system is widely used in the following fields:
picture 5 Application of exhaust system
Industrial production: Such as petroleum, chemical, pharmaceutical, printing and other industries, the waste gas generated contains a large amount of harmful substances and needs to be purified.
Domestic waste treatment: The odorous gas generated by waste incineration plants, landfills, etc. has a great impact on the surrounding environment, and it is necessary to use a waste gas deodorization system for treatment.
Municipal facilities: Such as sewage treatment plants, pumping stations, etc., will also produce odorous gases, and corresponding deodorization measures need to be adopted.
Ⅴ.Precautions
Select appropriate treatment technology: Select appropriate treatment technology according to the waste gas composition, concentration and treatment requirements to ensure treatment effect and economic benefits.
Regular maintenance and management: Regular maintenance and management of the exhaust gas deodorization system to ensure stable operation of the equipment and extend its service life.
Comply with environmental laws and regulations: Strictly comply with national and local environmental laws and regulations and standards to ensure that the exhaust gas after treatment meets the emission standards.
