Introduction to Catalytic Combustion Environmental Protection Equipment:

What is catalytic combustion?

Catalytic combustion exhaust gas treatment equipment refers to the combustion of exhaust gas under the action of a catalyst, which decomposes organic exhaust gas into carbon dioxide and water vapor. The catalyst enables the organic exhaust gas to undergo flameless combustion at low temperatures. Compared with regenerative combustion (RTO), catalytic combustion has lower temperature, combustion efficiency, and is safe and reliable.

The research and application of our company's catalytic combustion exhaust gas treatment equipment have entered a rapid development stage, and its role is increasingly valued and recognized by enterprises.

For simpler applications, the introduction of catalytic combustion technology in automobiles and other motor vehicles saves fuel, reduces waste emissions, and greatly reduces the degree of environmental pollution. Applied in coal-fired boilers, it realizes the combustion process of lean fuel, breaks the flammability limit of traditional flame combustion, and can further improve the combustion efficiency and thermal efficiency of gas furnaces.

Furthermore, catalytic combustion technology has also been successfully applied in other fields, such as catalytic combustion of * and calcination of cement clinker, but further in-depth research is still necessary, such as the application research of heating furnace tube burning technology in petrochemical enterprises, and so on.

The wide application and great significance of catalytic combustion field play a crucial role in future social development, promoting energy conservation and consumption reduction, rational utilization of resources, and environmental protection. Therefore, vigorously promoting research on catalytic combustion technology and actively promoting its application have profound and positive significance for the development of society and the protection of the environment.

The catalytic combustion equipment produced by our company is in line with the actual situation and environmental innovation trend. We have developed large, medium, and small catalytic equipment, which has a purification rate of over 95% in actual operation. It is easy to maintain and requires less one-time investment. Compared with most current waste gas treatment equipment, such as activated carbon, washing towers, and plasma purifiers, environmental protection equipment can handle high air volume and low concentration organic waste gas. They have multiple disadvantages, such as high energy consumption, large footprint, and difficult maintenance in the later stage. Catalytic combustion adopts PLC control, touch screen operation, simple operation, and easy maintenance.

Characteristics of catalytic combustion equipment

According to the fact that catalysts oxidize organic compounds at low temperatures (200-350 ℃), they have low energy consumption, simple operation, safety, and high purification efficiency. They are widely used in the purification of organic waste gases, especially those with little recycling value, such as chemical, painting, insulation materials, enameled wire, coating production, etc. There are already many molding equipment available for selection. Catalytic combustion is currently a very reasonable equipment for treating organic waste gases.

What are the main components of catalytic combustion exhaust gas treatment equipment?

The catalytic combustion device mainly consists of a heat exchanger, combustion chamber, catalytic reactor, heat recovery system, and exhaust chimney for purifying the flue gas chamber.

What is the working principle of catalytic combustion?

Usually, organic waste gas is introduced into the purification device heat exchanger through the action of a induced draft fan for heat exchange, and then sent to the heating chamber. Through the heating device, the gas reaches the catalytic reaction temperature, and then through the catalytic bed catalyst, the organic gas is decomposed into carbon dioxide, water, and heat energy. The reacted gas then enters the heat exchanger for heat exchange with low-temperature gas, causing the incoming gas to warm up and preheat. In this way, the heating system only needs to compensate for heating through the automatic control system, and can be * burned, saving energy. The effective removal rate of exhaust gas reaches over 97%, which meets the national emission standards.

The entire process flow of catalytic combustion

1. Preprocessing

Due to the presence of a certain amount of viscous dust and impurities in the exhaust gas, if it is not removed and directly enters the adsorption device, it is highly likely to cause micro pore blockage of the adsorption material (honeycomb activated carbon), seriously affecting the adsorption effect, increasing system resistance, affecting ventilation effect, and even posing safety hazards. Therefore, this process sets up an efficient water washing purification tower and a dehydration defogger as preprocessors before the paint exhaust gas enters the adsorption bed to efficiently remove dust and viscous particles and other dust and impurities in the exhaust gas, thereby ensuring that the dust and impurities in the exhaust gas introduced by the original supporting fan are effectively intercepted and filtered when entering the fixed adsorption bed.

The use of alkaline washing absorption can efficiently remove particulate matter, soluble organic waste gas, acidic gases, and organic components that can react with alkaline solution from exhaust gas. The alkaline washing tower adopts a two-stage washing, two-stage absorption purification, and one layer dehydration and dehazing structure, which can efficiently remove harmful components from exhaust gas and provide relatively clean pretreatment for subsequent treatment processes.

2. Adsorption

After removing dust and impurities, the exhaust gas is evenly distributed through the overcurrent section of the activated carbon layer in the fixed adsorption bed through reasonable air distribution. After a certain residence time, physical adsorption (also known as van der Waals adsorption) occurs due to the mutual attraction between the activated carbon surface and organic waste gas molecules. Each device is equipped with three adsorption beds, where the exhaust gas passes through two adsorption beds and the other is in the desorption regeneration stage or standby stage, so that the adsorption process can be carried out continuously without affecting workshop production.

3. Catalytic desorption

The adsorption bed with activated carbon reaching saturation state should stop adsorption and enter desorption state through valve switching. The process is as follows: start the desorption fan, open the corresponding valve and far-infrared electric heater, preheat the catalyst inside the catalytic combustion bed, and generate a certain amount of hot air. When the bed temperature reaches the set value, the hot air is sent into the adsorption bed. Activated carbon is pyrolyzed to extract high concentration organic gas, which is introduced into the catalytic combustion bed through the desorption fan. Under the action of precious metal catalyst, it undergoes flameless catalytic combustion at a lower temperature, converting organic components into non-toxic and harmless CO2 and H2O, At the same time, a large amount of heat is released to maintain the ignition temperature required for catalytic combustion, so that the exhaust gas combustion process does not require additional energy consumption (electricity), and part of the heat is reused for desorption and regeneration of activated carbon in the adsorption bed, greatly reducing energy consumption.

2. Easy to operate: The device can achieve automatic control during operation.

3. Waste heat can be reused: Waste heat can be returned to the drying oven, reducing the power consumption in the original drying oven; It can also be used as a heat source in other aspects.
