The zeolite rotor consists of three zones: adsorption, desorption, and cooling. In the adsorption zone, low-concentration waste gas passes through, allowing VOCs to be adsorbed while the purified gas is discharged. Once the rotor is saturated, it moves to the desorption zone, where a small amount of hot air (180-220°C) regenerates the zeolite. After desorption, the rotor enters the cooling zone before returning to the adsorption zone to repeat the cycle, achieving a concentration ratio of 5-30 times and a purification rate of 95-98%.

Primarily used for low-concentration exhaust gases in industries like coating and printing, the zeolite rotor can concentrate these gases for further treatment in an RTO. Depending on specific industry needs, Ever-Power customizes the zeolite materials and concentration ratios, ensuring effective treatment and receiving positive feedback from customers. The processing capacity of a single device ranges from 1,000 m³/h to 200,000 m³/h.

Zeolite Rotor Applications

In the printing industry, zeolite rotors are engineered to target the specific challenge of VOC molecules typically sized between 3.2Å and 5.5Å. The selection of the appropriate molecular "cages" within the zeolite structure is critical and is customized based on the precise composition and concentration of the customer's exhaust stream. Given that waste gas components can fluctuate significantly with different printing inks and processes, a zeolite formulation with broad adaptability is essential. Ever-Power rotors are specifically designed to perform reliably under these variable conditions, ensuring consistent purification efficiency despite process changes.

The coating industry presents a similar challenge with a different molecular profile, where VOC sizes generally range from 3.5Å to 6.9Å. This necessitates a distinct zeolite rotor configuration with a larger pore structure to effectively capture these bigger molecules. Just as with printing applications, the optimal rotor is tailored to the user's unique mix of solvents and operating parameters. Ever-Power technology platform excels here by providing robust solutions that maintain high adsorption efficiency and operational stability across the diverse and often shifting processes found in coating operations.

The Role of Zeolite Rotor

The Zeolite Molecular Sieve Rotor is frequently combined with a rotary RTO (Regenerative Thermal Oxidizer) to create an efficient waste gas treatment system. This integration leverages the specialized capabilities of both technologies for waste gas heat energy utilization and EPC general contracting projects. The company has successfully completed 41 projects dealing with chlorine and sulfur-containing waste gases using advanced anti-corrosion technology. After the rotor concentrates the waste gas, it flows into the RTO for incineration, which not only reduces equipment investment but also lowers operating costs. This combined system can concentrate waste gas by 10-20 times, allowing the RTO to treat high-concentration waste gases with a thermal efficiency exceeding 95%.

One of the key benefits of using the Zeolite Molecular Sieve Rotor alongside the RTO for VOCs treatment is the ability to recover waste heat, such as steam, hot water, or hot oil, evidenced by 98 successful steam waste heat recovery projects. The system is designed to be straightforward, incorporating regenerative heaters and fans, while its non-flammable design enhances safety. In solutions for low-temperature methanol washing waste gas in the chemical industry, the rotor combined with the RTO effectively treats methane and carbon monoxide, achieving both environmental protection and energy savings.
