Rotary enrichment + RTO combined technology
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;
