Он Zeolite Adsorption-Desorption Catalytic Combustion System (often abbreviated as Zeolite + CO) is an advanced, integrated environmental protection equipment designed to tackle the most challenging industrial emissions: high-volume, low-concentration Volatile Organic Compounds (VOCs).

By utilizing an innovative adsorption-concentration-desorption-combustion synergistic process, this system effortlessly overcomes the severe drawbacks of traditional standalone technologies, such as the exorbitant energy consumption of direct combustion and the dangerous secondary pollution associated with activated carbon replacement. This makes our product a highly cost-effective and perfectly matched alternative to premium global benchmarks like the Munters Zeolite Rotor или Dürr Megtec VOC Systems, delivering identical or superior destruction efficiency at a fraction of the capital expenditure.

The genius of the Zeolite system lies in its ability to convert massive volumes of dilute polluted air into a tiny volume of highly concentrated gas, which is then destroyed using minimal energy.

• Step 1: Pre-treatment Filtration
  Raw exhaust enters the dry filter. Particulate matter is efficiently intercepted by synthetic fiber cotton to prevent the downstream molecular sieves from blinding.
• Step 2: Adsorption & Concentration
  The filtered gas routes into Adsorption Tanks (e.g., Tanks A/B). The Zeolite traps the VOCs, and purified air is discharged. When Tank A nears saturation, pneumatic valves redirect the airflow to a standby Tank C.
• Step 3: Thermal Desorption
  A highly controlled stream of hot air flows through the saturated Tank A. The heat releases the trapped VOCs, concentrating them up to 20 times their original density.
• Step 4: Catalytic Combustion
  The concentrated VOCs enter the heat exchanger and then the catalytic bed. Under the action of precious metal catalysts, the organic substances undergo flameless oxidation at just 250°C - 350°C, breaking down into harmless Carbon Dioxide (CO&sub2;) and Water (H&sub2;O). The released exothermic heat is recycled back into the system.

🔋 Unmatched Energy Savings

Once the concentrated exhaust reaches the catalytic chamber, the exothermic reaction generates sufficient thermal energy to maintain self-sustaining combustion. This nearly eliminates the need for auxiliary electricity or natural gas heating during steady-state operations.

🔃 Continuous 24/7 Operations

Utilizing a multi-bed (A/B/C) parallel alternating switching mechanism. The system systematically rotates between adsorption and desorption without ever needing to halt your factory's production lines.

🛡 Absolute Operational Safety

Catalytic combustion operates at a low temperature (flameless oxidation). Integrated with rigorous explosion-proof relief valves, flame arresters, and multi-point temperature/pressure PLCs, completely eliminating industrial fire hazards.

🌱 Отсутствие вторичного загрязнения

Permanently converts volatile organic compounds into CO&sub2; and H&sub2;O. This totally eradicates the exorbitant hazardous waste disposal costs and secondary pollution risks associated with constantly replacing saturated activated carbon.

🎯 Unyielding Precision

Zeolite molecular sieves feature uniform pore sizes (0.3~1nm) providing incredible shape-selective and polarity-based adsorption. It specifically targets and locks onto VOC molecules even in high-humidity exhaust environments.

A. High-Efficiency Dry Filter

Exhaust gas is introduced through the pipeline, passing through progressive filter media. We utilize multi-stage bag filtration (G4-F5-F9-H10 grades) made of high-quality synthetic fibers. This guarantees particle removal efficiency from >5μm down to ≥0.5μm. The robust bag shape ensures airflow evenly inflates the media, drastically reducing aerodynamic resistance and extending the filter's service life.

B. Modular Adsorption Box

The equipment box is fabricated from high-grade carbon steel with premium anti-rust surface treatments. Internally, the zeolite is designed in multiple layers to ensure uniform airflow distribution. The empty tower wind speed is strictly engineered at 0,8 - 1,5 м/с to maintain low resistance. Dedicated maintenance manholes, operation platforms, and modular cartridge designs make material replacement exceptionally safe and convenient.

C. Honeycomb Zeolite Adsorbent Media

Unlike standard activated carbon, our honeycomb molecular sieves are inorganic microporous materials composed of SiO&sub2; and Al&sub2;O&sub3;. Characterized by an immense specific surface area (300-1000 м²/г) and cavity diameters of 0.6~1.5nm, they offer incredible polarity-based adsorption. Because zeolite is completely non-flammable and possesses exceptional thermal stability, it allows for high-temperature thermal desorption using the residual hot air sourced directly from the catalytic oxidizer.

Q1: What makes Zeolite superior to Activated Carbon for VOCs?

Unlike activated carbon, which is highly flammable and loses effectiveness in humid environments, Zeolite molecular sieves are totally non-flammable, highly resistant to moisture, and can withstand high-temperature desorption. This allows Zeolite to be regenerated and reused thousands of times directly on-site.

Q2: What is the lifespan of the Zeolite media?

With proper operation and functional upstream dry filtration (to prevent dust and resin blinding), our premium honeycomb zeolite media typically lasts between 3 to 5 years, delivering an exceptional return on investment.

Q3: How much natural gas or electricity does the catalytic oxidizer use?

Because the Zeolite concentrates the VOCs up to 20 times, the gas entering the oxidizer is highly energy-dense. Once the catalytic bed reaches 250°C - 350°C, the exothermic reaction of the VOCs sustains the heat. Therefore, external energy consumption is usually near zero during steady-state operations.

Q4: Is the Catalytic Combustion process safe from fire hazards?

Yes, absolutely. Catalytic combustion is a flameless oxidation process occurring at relatively low temperatures. Furthermore, our systems are equipped with Lower Explosive Limit (LEL) monitors, flame arresters, and automatic fresh-air dilution valves to prevent any explosive concentrations.

Q5: Can it handle exhaust with high levels of paint mist?

Yes, provided the front-end filtration is adequate. Our system includes a heavy-duty Dry Filter module equipped with multi-stage bags (G4, F5, F9, H10) specifically engineered to intercept sticky particulates and paint mist before they can reach and damage the zeolite.

Q6: How does the Alternating Switching work?

In a multi-box system, while Box A and Box B are actively adsorbing VOCs from the factory, Box C is isolated and undergoing hot-air desorption. Once Box A is saturated, pneumatic valves automatically switch the raw gas to Box C, and Box A enters the desorption phase. This ensures 24/7 continuous treatment.

Q7: Are there any VOCs that Zeolite cannot treat?

Zeolite is highly effective for most standard industrial VOCs (Toluene, Xylene, Ethyl Acetate, Alcohols). However, it is not suitable for exhaust gases containing high concentrations of heavy metals, halogens (chlorine, fluorine), or sulfur compounds, as these can poison the precious metal catalysts downstream.

Q8: How do I know if I need a Zeolite System or an RTO?

If your exhaust has a very large volume but low VOC concentration, Zeolite + CO is the most cost-effective solution. If your exhaust has a high VOC concentration, directing it straight into a Регенеративный термоокислитель (РТО) is the better engineering choice. We will calculate the optimal route for you.

Q9: Is the system fully automated?

Absolutely. The entire system is governed by a central PLC control cabinet integrated with HMI touchscreens. It automatically manages valve switching, temperature regulation, fan speeds, and fault alarms without requiring constant manual supervision.

Q10: How do we initiate a custom project with you?
