The large air volume, low concentration, and room temperature volatile organic mixed waste gas to be treated is acted by the induced draft fan, and firstly passes through the pretreatment filter device to remove the dust particles and impurities in the waste gas, otherwise the direct adsorption will block the micro-shrinkage pores of the zeolite, thus affecting the adsorption effect Even ineffective, after preliminary filtration, “relatively pure organic waste gas” enters the zeolite rotor adsorption device for adsorption and purification treatment. The organic matter is trapped inside by the unique force of the rotor zeolite, and the clean gas is discharged. After a period of adsorption, When the zeolite runner reaches the saturated state, the runner automatically rotates into the cooling and high temperature desorption area. The high-concentration exhaust gas desorbed by the zeolite runner directly enters the regenerative combustion device (RTO) for high-temperature oxidation treatment. After the exhaust gas is oxidized, the high-temperature gas is discharged to exchange heat with the regenerative ceramics, so that the gas entering the RTO is preheated to 650-720 ℃ to reduce fuel consumption, the exhaust gas after heat exchange is directly used for desorption and the heat is insufficient and the oxygen content is low, but it can be directly used for adsorption of exhaust gas to increase temperature and dehumidify;
CO is an industrial organic waste gas purification device that uses a catalyst to decompose VOCs into water and carbon dioxide, and uses the heat storage capacity of the heat storage body to recycle the heat generated by the oxidation reaction of VOCs. It mainly includes reversing valve, heat storage bed, catalytic bed, heater and other equipment
The Regenerative Thermal Oxidizer is referred to as RTO, and its full name is (Regenerative Thermal Oxidizer). The basic principle is to oxidize organic waste gas (VOCs) to CO2+H2O under high temperature conditions (≥760°C), and the purification efficiency is as high as 99%. The high-temperature gas generated by oxidation flows through a special ceramic regenerator, which makes the ceramic body heat up and “reserve heat”. The next process is that the exhaust gas passes through the ceramic that has “regenerated heat”, and the heat of the ceramic is transferred to the exhaust gas, and the organic waste gas passes through. Ceramics are used as the carrier of the heat exchanger to perform heat exchange repeatedly, thereby saving fuel consumption for raising the temperature of exhaust gas, reducing operating costs, and the heat recovery efficiency is as high as 95%. Under medium and high concentration conditions, RTO can export waste heat to the outside and use it in the form of steam, hot air, hot water, etc., and achieve economic benefits while meeting environmental protection goals.
The washing unit is divided into water washing and chemical washing. Water washing can decompose water-soluble components such as ethanol. Chemical washing is also divided into pickling and alkali washing. According to different application occasions, washing has different treatment effects.
Activated carbon adsorber, activated carbon has the characteristics of large specific surface area, small through-hole resistance, developed micropores, high adsorption capacity, and long service life. The exhaust gas is in contact with the porous activated carbon with a large surface, and the pollutants in the exhaust gas are adsorbed and decomposed, thus playing a purification role
