Integrated zeolite wheel catalytic combustion unit

A concentrated rotary wheel device system adsorbs large-volume, low-concentration volatile organic compounds (VOCs), and then introduces the desorbed small-volume, high-concentration waste gas into an incinerator for decomposition and purification. For large-volume, low-concentration VOC waste gas, it passes through a rotary wheel using zeolite as the adsorbent material. The VOCs are adsorbed by the zeolite in the adsorption zone of the rotary wheel, and the purified gas is discharged into the atmosphere through a chimney. Then, in another desorption zone, a small amount of hot air at 180℃~230℃ is used to desorb the VOCs. This high-concentration, small-volume desorbed waste gas is introduced into an 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 for treating high-volume, low-concentration organic waste gas and saving operating costs. The process waste gas passes through a pre-filter to remove paint mist dust and particulate pollutants, and then is adsorbed by a concentrated rotary wheel containing hydrophobic zeolite to adsorb VOCs. The clean air is then discharged into the atmosphere. As the rotary wheel rotates slowly, it passes through the desorption zone, where it is desorbed by a small amount of high-temperature desorption air. The desorbed high-concentration waste gas is then introduced into a small incinerator or catalytic incinerator to decompose the VOCs. A secondary compensation heater is installed in the desorption process to supply desorption hot air, so as to achieve the purpose of energy saving.

The zeolite rotary wheel (also called molecular sieve) adsorption and concentration device adopts high-quality imported products from Japan. The adsorption material is zeolite. The zeolite structure is similar to a crystal, with molecules connected like a frame, forming many cavities in the middle, which creates many micropores with strong adsorption capacity. Its adsorption capacity for adsorbate molecules is far superior to other types of adsorbents.

The rotary wheel is usually divided into three parts: one large sector and two small sectors. The large sector is for adsorbing organic matter, and the two small sectors are the cooling zone and the high-temperature desorption zone respectively. The rotary wheel rotates at a certain speed, and the adsorbed zeolite automatically transfers to the desorption zone for desorption and regeneration, forming a continuous production where adsorption concentration and desorption regeneration run simultaneously.

The gas containing organic solvents becomes clean air after passing through the zeolite molecular sieve rotary wheel. The molecular sieve rotary wheel rotates continuously under the action of a motor. After the rotary wheel enters the regeneration zone, the organic solvents adsorbed on the rotary wheel are desorbed from the rotary wheel under the action of hot air. Since the air flow rate of the desorption rotary wheel is only 1/10~1/20 of the air flow treated by the rotary wheel, and the concentration after concentration is 10~20 times the original concentration. After the adsorption material adsorbs a certain amount of organic solvents, it must be heated and regenerated to desorb the organic solvents adsorbed on the adsorption material and restore its adsorption capacity. The desorption method of the adsorption material uses hot air circulating through the adsorption material. A certain amount of waste gas containing high-concentration organic solvents will be generated during the desorption process of the adsorption material. If this part of the waste gas is directly discharged into the atmosphere, it will cause environmental pollution, so this part of the waste gas must be properly technically treated into substances that are harmless to the atmosphere.
