The zeolite rotary device+catalytic combustion of CO is mainly suitable for treating high concentration CO waste gas. Usually, when the CO concentration is 500 ppm (volume fraction) or higher, a zeolite rotary device combined with catalytic combustion of CO is required for treatment. If the CO concentration is low, other waste gas treatment technologies may be more suitable. Zeolite rotary device is a technology used to separate components from gas mixtures. This type of device usually includes many zeolite molecular sieve wheels, which can selectively adsorb certain molecules without adsorbing other molecules, thereby achieving component separation in gas mixtures. Catalytic combustion of CO is a technology that converts CO (a toxic and harmful gas) into CO2 (a relatively harmless gas). This technology uses catalysts to accelerate the reaction between CO and oxygen, thereby reducing the concentration of CO.

Zeolite wheel+TO direct combustion furnace is an efficient and environmentally friendly industrial waste gas treatment equipment. It can effectively treat various organic pollutants in industrial waste gas through two methods: physical adsorption and high-temperature incineration.

The zeolite wheel+RCO catalytic combustion equipment is currently a mature and practical process in the field of organic waste gas treatment in China. Adopting a three step continuous program of adsorption desorption cooling, with simultaneous adsorption and desorption. The zeolite wheel first adsorbs and collects organic waste gas, compresses it, and increases its concentration. Then, high concentration waste gas molecules are desorbed from the zeolite wheel and sent to a catalytic oxidation furnace (CO furnace) for flameless combustion. To achieve the purpose of purifying organic waste gas. The zeolite wheel+RCO equipment mainly consists of exhaust gas pretreatment system, zeolite wheel adsorption concentration system, desorption system, catalytic combustion system, cooling and drying system, and automatic control system.

The zeolite wheel+RTO process is currently one of the hottest processes in the waste gas treatment industry. Compared to other new materials, industries such as new energy, chemical, and semiconductor directly use RTO for incineration. The zeolite wheel RTO process has very guaranteed compliance and safety performance. The working principle of zeolite rotary RTO is to use combustion reactions at high temperatures to oxidize organic compounds in exhaust gas into harmless carbon dioxide and water, thereby achieving the goal of purifying exhaust gas. Its core is a rotating heat exchanger filled with adsorption materials such as zeolite.

Spray tower, as a type of environmental waste gas treatment equipment, exists. According to its working principle, it can be divided into circulating water spray tower, alkali spray tower, and acid spray tower (also known as acid washing tower). According to the material of the tower, it is divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers. Choose a reasonable spray material and spray process based on the different properties of the exhaust gas. Spray tower is an important industrial waste gas treatment equipment, whose working principle is to use water and power technology to spray liquid or gas in a mist form into the waste gas, in order to remove harmful substances in the waste gas.

Washing tower is a mature waste gas treatment equipment widely used in pre-treatment of industrial waste gas treatment, dust removal, and other aspects. Gas enters the tower and fully contacts, adsorbs, and dissolves with the washing liquid inside the tower, achieving purification effect. The design forms of Yi cleaning towers are diverse, and vertical or horizontal structures can be used according to the project application site. The commonly used materials for washing tower equipment include PP, FRP, and stainless steel. PP and FRP are commonly used in chemical absorption towers and have the characteristics of acid resistance, alkali resistance, and corrosion resistance. Stainless steel materials can be used for high-temperature exhaust gas.

Regenerative catalytic combustion (RCO) is a method of using catalysts to decompose organic waste gases into harmless small molecules such as carbon dioxide and water. Due to the need to consume heat in the reaction, it is called regenerative catalytic combustion method. The RCO device mainly consists of three parts: a purification chamber, a preheating chamber, and a high-temperature gas outlet, with the temperature of the preheating chamber generally ranging from 300 to 600 ° C; The purification room is equipped with a packing layer to adsorb pollutants from organic waste gas; The high-temperature gas outlet is connected to the atmosphere to recover heat.

The English name of a regenerative thermal incinerator is "Regenerative Thermal Oxidizer", therefore it is abbreviated as "RTO". The principle is to heat the organic waste gas to above 800 degrees Celsius, causing the VOC in the waste gas to oxidize and decompose into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and "store heat". This "heat storage" is used to preheat the subsequent organic waste gas entering, thereby saving fuel consumption for waste gas heating. The ceramic heat storage body should be divided into three compartments, each of which should go through the procedures of heat storage, heat release, and cleaning in sequence, and work continuously. After the heat storage chamber releases heat, a portion of the treated and qualified clean exhaust should be immediately introduced to clean the chamber (to ensure a VOC removal rate of over 95%). Only after the cleaning is completed can the "heat storage" program be entered.

Catalytic combustion is a purification method that uses a catalyst to oxidize and decompose combustible substances in exhaust gas at lower temperatures. So, catalytic combustion is also known as catalytic chemical conversion. Due to the catalyst accelerating the process of oxidation and decomposition, most hydrocarbons can be completely oxidized through the catalyst at temperatures ranging from 300 to 450 ℃. Compared with thermal combustion, catalytic combustion requires less auxiliary fuel, consumes less energy, and has a smaller volume of equipment and facilities. However, due to the poisoning of the catalyst used, the replacement of the catalytic bed, and the high cost of cleaning, the promotion and application of this method in industrial production processes have been affected.

Direct combustion incinerators process VOCs through the principle of high-temperature oxidation. The internal structure of conventional furnaces is a cavity structure, and various heat recovery devices such as heat exchangers and boilers can be installed outside the furnace according to customer needs. Direct combustion incinerators can be widely used for complex waste gases with high concentrations and particulate matter, and effectively recover the heat energy released during the oxidation process. Direct combustion incinerators have diverse shapes and can be designed according to the characteristics of the site space, such as square and cylindrical chambers. They can also be made into vertical furnaces, horizontal furnaces, L-shaped furnaces, etc.
