Under the condition of low temperature, the large air volume of organic waste gas passes through the zeolite molecular sieve rotating wheel, VOCs molecules are adsorbed on the surface of the zeolite molecular sieve rotating wheel, and the waste gas passing through the zeolite rotating wheel can be directly discharged; the zeolite rotating wheel part with a large amount of VOCs adsorbed enters a high-temperature desorption area, VOCs molecules on the zeolite rotating wheel are desorbed by using low-air-volume high-temperature waste gas to form high-concentration waste gas, the high-concentration waste gas is sent to a waste gas oxidation system at the rear end for catalytic oxidation treatment, and the purified waste gas can be directly discharged; the sizes of the pore canal and the hole diameter in the zeolite molecular sieve are determined, and the zeolite molecular sieve is the special pore canal structure, so that macromolecular substances cannot enter the interior of the zeolite molecular sieve and can only pass through the zeolite molecular sieve with the molecular diameter smaller than the pore canal diameter, and the zeolite has selective adsorption. In addition, the molecular structure of the zeolite molecular sieve has strong polarity, so that polar molecules can be more easily adsorbed during adsorption, the adsorption effects of the zeolite molecular sieve are superposed under the dual actions of physics and chemistry, and the adsorption performance is greatly improved. Compared with activated carbon, the zeolite molecular sieve also has large electrostatic force, and due to the existence of the electrostatic force, the zeolite molecular sieve can better selectively adsorb substances with small concentration, strong polarity and difficult volatilization. The molecular sieve used for producing the rotating wheel is various hydrophobic molecular sieves with high silica-alumina ratio and combined molecular sieves thereof. One or more combined molecular sieves can be selected according to the properties of VOCs waste gas components of different customers, so that the purification efficiency and the concentration efficiency are improved to the maximum extent. The adsorption capacity is large, the single-stage adsorption efficiency can reach 90-98%, and the adsorption capacity is still strong at a high temperature.
1) The zeolite molecular sieve runner area is divided into three functional areas of an adsorption area, a desorption area and a cooling area (the area ratio is 10: 1: 1) the zones are separated by a heat and solvent resistant sealing material. The zeolite molecular sieve rotating wheel continuously runs in each functional area.
2) And the waste gas is sent to an adsorption area of a zeolite molecular sieve rotating wheel after passing through a preposed multistage filter. VOCs in the organic waste gas in the adsorption zone are adsorbed and removed by the zeolite molecular sieve, and the organic waste gas is purified and then discharged from the zeolite molecular sieve rotating wheel adsorption zone and directly discharged into a chimney to reach the standard.
3) And the VOCs adsorbed in the molecular sieve rotating wheel are desorbed and concentrated (5-30 times) in a desorption area through hot air treatment. And the desorbed small-air-volume high-concentration waste gas enters a thermal oxidation device at the rear end for purification treatment.
4) And in order to ensure high adsorption efficiency, the rotating wheel after high-temperature desorption needs to be cooled. The desorbed and regenerated zeolite molecular sieve rotating wheel is cooled in a cooling zone. The air passing through the cooling area is heated and then used as regeneration air, so that the effect of energy conservation is achieved.
The model of the RTO zeolite runner catalytic combustion all-in-one machine is 30K-Plus, the diameter (mm) of the runner is 1950-V, the thickness (mm) of the runner is 500, the multistage filter is G4/F7/activated carbon/H10, and the shell is made of carbon steel plate spray paint.
The waste gas after multistage treatment and filtration is finally treated by adopting a process of zeolite wheel concentration and catalytic oxidation; the process of zeolite wheel concentration and catalytic oxidation is designed by utilizing the principle of large specific surface area of zeolite and different intermolecular forces under different temperature conditions. Under the condition of low temperature, the large air volume of organic waste gas passes through the zeolite molecular sieve rotating wheel, VOCs molecules are adsorbed on the surface of the zeolite molecular sieve rotating wheel, and the waste gas passing through the zeolite rotating wheel can be directly discharged; the treatment process comprises the following steps: the zeolite runner part that adsorbs there are a large amount of VOCs gets into the high temperature desorption district, utilizes the high temperature waste gas of little amount of wind to come out the VOCs molecule desorption on the zeolite runner, forms high concentration waste gas, sends into the waste gas oxidation system catalytic oxidation of rear end and handles, and the waste gas after the purification can directly be discharged. After being pretreated, organic waste gas (after being adsorbed and concentrated) enters a catalytic oxidation furnace heat exchanger under the action of a CO main fan to exchange heat with catalyzed high-temperature flue gas, the organic waste gas after heat exchange enters a catalytic oxidation reaction chamber, is preheated by an auxiliary heating device (electric heating), is heated to the temperature required by catalytic oxidation to generate catalytic oxidation reaction, is oxidized into CO2 and H2O in a catalytic bed, and is discharged to the atmosphere after being subjected to heat exchange and temperature reduction after entering the catalytic oxidation furnace heat exchanger.
