Molecular Sieve Adsorption Concentration Rotor Tunnel Furnace

The Molecular Sieve Adsorption Concentration Rotor Tunnel Furnace is an industrial-grade continuous hot air circulation heating system. It is specially designed for high-temperature desorption and thermal regeneration of molecular sieve adsorption rotors, which are the core components in VOCs treatment systems for large air volume and low-concentration organic waste gases. By providing stable and uniformly distributed continuous hot air, the equipment enables efficient desorption of VOCs adsorbed inside the molecular sieve.

Product Applications

High-Temperature Rotor Regeneration:

Used for continuous heating desorption of molecular sieve rotors after adsorption saturation, effectively removing high-boiling-point organic compounds.

System Integration Support:

Serves as the key heating unit in VOCs treatment systems combining rotor concentration technology with regenerative thermal oxidizers (RTO) or catalytic oxidizers (CO).

Performance Recovery Activation:

Used for periodic high-temperature activation and restoration of molecular sieve rotors whose adsorption efficiency has decreased due to long-term operation.

FAQ

Q1: What desorption temperature is generally recommended for this tunnel furnace?

A1: The typical desorption temperature for molecular sieve rotors is 180℃ to 220℃. For high-boiling-point compounds, regeneration may require temperatures above 250℃. The actual setting depends on the VOC composition and process requirements.

Q2: How does the equipment ensure uniform heating of large-volume rotors inside the furnace?

A2: The equipment adopts multi-zone independent temperature control combined with dual-side forced hot air circulation. Together with slow rotation or stable conveying, it ensures the temperature difference between different parts of the rotor remains within ±3℃.

Q3: How are VOC gases released during the heating desorption process handled?

A3: A dedicated exhaust outlet is installed on the top of the tunnel furnace. The high-concentration VOC gases released during desorption are directly transported through pipelines to subsequent RTO or CO oxidation equipment for complete treatment.

Q4: What heating methods are available for this equipment?

A4: The system supports electric heating, gas heating, and factory waste heat steam heating. Users can select the most suitable energy source according to existing factory conditions and operating costs.

Q5: How effective is the insulation performance during continuous operation?

A5: The furnace body is filled with more than 150 mm thick high-density aluminum silicate fiber insulation material. The external surface temperature remains close to ambient temperature, minimizing heat loss and preventing operators from being exposed to high-temperature surfaces.
