Zeolite rotor

The concentrated rotor device system adsorbs large-volume, low-concentration volatile organic compounds (VOCs), and then introduces the small-volume, high-concentration exhaust gas after desorption into an incinerator for decomposition and purification. The large-volume, low-concentration VOC exhaust gas passes through a rotor with zeolite as the adsorption material. After the VOCs are adsorbed by the zeolite in the adsorption area of the rotor, the purified gas is discharged into the atmosphere through a chimney. Then, in another desorption area, a small amount of hot air at 180℃～230℃ is used to desorb the VOCs. The high-concentration, small-volume desorbed exhaust gas is then introduced into the incinerator to be decomposed into carbon dioxide and water vapor, and the purified gas is discharged into the atmosphere through a chimney. This concentration process greatly reduces fuel costs; this system is one of the technologies that save operating costs when treating high-volume, low-concentration organic exhaust gas. The process exhaust gas first passes through a pre-filter to remove paint mist dust and particulate pollutants, and then passes through a concentrated rotor containing hydrophobic zeolite to adsorb VOCs, and the clean air is discharged into the atmosphere. Since the rotor rotates slowly, it will pass through the desorption area, and the VOCs are desorbed by a small amount of high-temperature desorption air. The desorbed high-concentration exhaust gas is then introduced into a small incinerator or catalytic incinerator to decompose the VOCs. The desorption process is equipped with a secondary compensation heater to supply desorption hot air, so as to achieve the purpose of energy saving.

The zeolite rotor (also called molecular sieve) adsorption and concentration device uses high-quality products imported from Japan. The adsorption material is zeolite. The structure of zeolite is similar to a crystal, and the molecules are connected like building a frame, forming many cavities in the middle, which creates many micropores and has strong adsorption capacity. The adsorption capacity for adsorbate molecules is far stronger than other types of adsorbents.

The rotor is usually divided into three parts: a large sector and two small sectors. The large sector is used for adsorbing organic matter, and the two small sectors are respectively the cooling area and the high-temperature desorption area. The rotor rotates at a certain speed. After adsorption, the zeolite automatically transfers to the desorption area for desorption and regeneration, so that adsorption concentration and desorption regeneration run simultaneously, realizing continuous production.

The gas containing organic solvents becomes clean air after passing through the zeolite molecular sieve rotor. The molecular sieve rotor rotates continuously under the action of a motor. After the rotor enters the regeneration area, the organic solvents adsorbed on the rotor are desorbed from the rotor under the action of hot air. Since the air flow rate of the desorption rotor is only 1/10～1/20 of the air flow rate treated by the rotor, the concentration after concentration is 10～20 times the original. After the adsorption material adsorbs a certain amount of organic solvents, it must be heated for regeneration to desorb the organic solvents adsorbed on the adsorption material and restore its adsorption capacity. The desorption method of the adsorption material is to use hot air to circulate through the adsorption material. During the desorption process of the adsorption material, a certain amount of exhaust gas containing high-concentration organic solvents will be generated. If these exhaust gases are directly discharged into the atmosphere, they will cause environmental pollution, so this part of the exhaust gas must be treated with reasonable technology to turn it into substances that are harmless to the environment.
