Zeolite Wheel Integrated Machine is the next generationVOCs treatment equipment is a method that organically combines an adsorption concentration unit with a thermal oxidation unit. The Zeolite Wheel Concentration Adsorption Unit utilizes a continuous three-step temperature change of adsorption, desorption, and concentration to concentrate low-concentration, high-volume organic waste gases into high-concentration, low-flow concentrated gases. Its unit characteristics are suitable for treating waste gases with high flow rates, low concentrations, and multiple organic components.

By rotating the wheel, the desorption of the gas and the regeneration of the wheel can be simultaneously completed on the wheel.VOCs emissions are effectively adsorbed into the zeolite after passing through a hydrophobic zeolite concentrator wheel, achieving the removal purpose. The clean gas of volatile organic compounds after zeolite adsorption is directly emitted into the atmosphere through the chimney. The wheel rotates at a speed of 1-6 rotations per hour, simultaneously transferring the adsorbed VOCs to the desorption zone. In the desorption zone, a small amount of heated gas is used to desorb the VOCs. After desorption, the zeolite wheel rotates back to the adsorption zone to continuously adsorb volatile organic waste gases. The desorbed concentrated organic waste gas is then sent to an incinerator for combustion, converting it into carbon dioxide and water vapor, which are emitted into the atmosphere.

But in different practical application scenarios, the composition of exhaust gas is complex and prone to high boiling points.VOCs residue aggregation and smoldering phenomena.

High-boiling point VOCs residue polymer

Waste gas treatment contains high boiling point substances.During the desorption of VOCs, if the desorption heat is insufficient, the adsorbate is not fully desorbed, leading to the accumulation and residual of the adsorbate in the vicinity of the adsorption site. Over time, this can cause aggregation, which in turn blocks the zeolite adsorption sites, weakening the adsorption efficiency in that area. To facilitate the desorption of high-boiling-point VOCs adsorbed in zeolite, the following suggestions are provided:

(1) Install high-boiling point VOCs removal equipment at the front end

To avoid high boiling pointsDifficulties in desorption due to VOCs substance adsorption can be addressed by adding a pre-filter cloth or activated carbon filter before the exhaust enters the adsorption wheel, or by installing a dehumidifier or condenser to remove high-boiling point VOCs first.

(2) Increase desorption heat capacity

Method one to increase the desorption temperature suggests controlling the temperature atBetween 180-200°C, no more than 220°C to avoid excessive residual heat leading to cooling and affecting the adsorption section's effectiveness; another method is to increase the desorption air volume and decrease the concentration ratio, which can achieve a full desorption effect.

Product Features:

1. High adsorption and desorption efficiency convert VOCs waste gases with high airflow and low concentration into low airflow and high concentration, reducing the cost of downstream terminal treatment equipment.

2. Zeolite wheel adsorption of VOCs results in reduced pressure drop, significantly decreasing electrical energy consumption.

3. Concentration ratio up to 5-20 times, significantly reducing the specifications of post-treatment equipment and lowering operating costs.

4. The overall system features pre-assembled and modular design, offering the smallest space requirement while providing continuous and unmanned operation modes.

The exhaust gas after the centrifugal concentration can meet the national emission standards.

Industry Adaptation: Particularly suitable for high volume, low concentration environments, including: printing, large-scale spray painting workshops, furniture, semiconductor chips, liquid crystal.LED industrial and manufacturing facilities.
