Today I would like to talk to you about the topic of catalytic combustion, interested guests can actively speak Oh!

China's manufacturing capacity in recent years, the achievements of everyone can see. Looking around the world in our second no one dares to call the first position of boldness. However, the relationship between industrial manufacturing capacity and environmental pollution has never been full of contradictions. Like painting, printing, home appliances, petrochemical plants, chemical plants, pharmaceutical plants, cigarette factories and other industries, in the production process will produce a large number of environmentally harmful organic waste gas, these emissions must be treated before they can be discharged into the atmosphere.

The equipment that separates the dust from the flue gas is called a dust collector or dust removal equipment. The performance of a dust collector is expressed in terms of the volume of gas that can be treated, the resistance loss of the gas as it passes through the dust collector and the dust removal efficiency. Also, the price, operation and maintenance costs, length of service life and ease of operation and management of the dust collector are important factors in considering its performance. Dust collectors are commonly used facilities in boiler and industrial production. Organic exhaust gas can be concentrated into small air volume and high concentration by activated carbon adsorption, and then enter RCO unit for treatment, which can save operation cost. After the exhaust gas is effectively collected and pretreated, it enters the activated carbon adsorption device. The gas is kept in the activated carbon bed for a certain residence time, and the VOCs in the gas are adsorbed on the surface of the activated carbon, and the clean gas can be discharged from the activated carbon bed directly through the induced draft fan. The concentrated organic matter desorbed from the activated carbon adsorption device enters the RCO device and is decomposed through the combustion of precious metal catalyst, the decomposition temperature is 200-250℃, the organic waste gas is decomposed into carbon dioxide and water, in this cycle, after the decomposition of the waste gas desorption is completed, it is discharged into the flue pipe and meets the emission standards.

Mechanical dust cleaning type: This dust cleaning method can include manual vibration, mechanical vibration, etc., is a simple dust cleaning method. Generally speaking, the vibration distribution of the filter bag along the axial direction of mechanical vibration is not uniform, and the acceleration decay is faster, the length of the filter bag is generally shorter, and the filter air speed is also smaller. Mechanical vibration cleaning bag dust collector uses mechanical motion device to make the filter bag for periodic vibration, so that the dust particles adhering to the filter bag fall into the dust hopper. According to different vibration methods, it can be divided into three forms: horizontal vibration, vertical vibration and twisted vibration. Segmentation of the product market, China's dust collection equipment manufacturing industry market size is still mainly divided by the electric dust collector and bag dust collector. Among them, the electric dust collector is used in China earlier, and is the mainstream dust removal equipment for coal-fired power plants with ultra-low emissions. The CEC statistics show that since 2000, the market share of electric dust removal in the power industry has remained above 66. However, the market demand for electric dust removal in the power industry has fallen, and the market size of electric dust removal has declined in recent years. According to previous data from China Environmental Protection Industry Association, in 2017, the market size of electric dust removal was about 12.868 billion yuan, a decline of 18.56; however, with the replacement of technology, the market size rebounded to 14.1 billion yuan in 2018. 2019 and 2020 years by the epidemic and the global economic downturn, the market size fell more seriously.

At present, many companies will use SROC catalytic combustion equipment, why everyone will choose to use SRCO catalytic combustion device to treat exhaust gases, what are its advantages?
1, can treat almost all exhaust gases
The use of SRCO catalytic combustion equipment can basically treat all exhaust gases containing organic compounds, can handle organic exhaust gases with large air volumes and low concentrations, and can adapt to changes and fluctuations in the composition and concentration of organic waste gas VOCs, as well as the entrainment of a small amount of dust and solid particles can also be processed.
2、The operation process does not produce secondary pollution
Catalytic combustion equipment using adsorption concentration catalytic combustion, the purification, desorption process closed cycle, especially the operation process does not produce secondary pollution, and one is not equipped with additional energy, such as compressed air this additional energy does not have to use, which greatly reduces the investment in equipment and operating costs.
3, the principle of advanced equipment design.
Another advantage of catalytic combustion equipment is in the design, advanced design principles, unique materials, the most important is the performance and stability, easy to operate, can achieve safety and reliability, energy saving, no secondary pollution and a series of advantages.
In addition to the above-mentioned advantages of the familiar SRCO catalytic combustion device, but also has the advantages of high adsorption efficiency, adsorption capacity, wide application, precious metal catalysts, low resistance, high activity, as well as organic waste gas can be adsorbed activated carbon bed, etc., so I recommend the use of the equipment for the waste gas enterprises.

It should be noted that the use of exhaust gas treatment equipment, there should be a set of operational management system suitable for their actual situation, such as job responsibility, transfer system, detection system, exhaust gas treatment equipment maintenance, overhaul system, health inspection system, quality control system and economic accounting system. Industry in the daily use of plasma photo-oxidation equipment for exhaust gas treatment, often ignore the maintenance of exhaust gas treatment equipment, resulting in the actual use of the process more or less encountered this or that problem. Therefore, I would like to remind you all to see the old man, exhaust gas treatment equipment in the actual use of the maintenance work must be done, otherwise not only will there be problems, but also seriously affect the life of the exhaust gas treatment equipment.

Well, today's topic to talk about here, said the wrong place, welcome to correct! If you have a different opinion, welcome to give Yi Xiaobian message comments, we discuss together! If you like the content of the editor, welcome to comment praise plus attention Oh!
