Zeolite Rotary Concentration + Catalytic Combustion Treatment System
key word: Zeolite Rotary Concentration + Catalytic Combustion Treatment System
Product Description
Overview
The zeolite rotary adsorption and concentration–catalytic oxidation system is currently a mature technology employed by our company for the treatment of organic waste gases. The system consists of two main components: a hydrophobic zeolite rotor and a catalytic oxidation unit. It leverages the high adsorption capacity of zeolite molecular sieves to adsorb and concentrate organic waste gases, which are then treated by a low-temperature catalytic oxidation unit to remove the concentrated organic compounds.
Working Principle
The main components of zeolite are silicon and aluminum, and it possesses adsorption capacity, making it suitable for use as an adsorbent. A zeolite rotary concentrator leverages the specific pore size of zeolite to selectively adsorb and desorb organic pollutants, thereby concentrating large-volume, low-concentration VOC exhaust gases into a smaller-volume, high-concentration stream. This concentration process reduces the operating costs of downstream end-of-pipe treatment equipment.
Rotary adsorption purification unit—this system employs a solid adsorption bed to adsorb and concentrate organic gases. The rotor is divided into three zones by specially designed sealing devices on both sides: the adsorption zone, the desorption zone, and the cooling zone. After preliminary treatment and filtration to remove paint mist, particulates, and moisture, the waste gas is passed uniformly through the cross-section of the slowly rotating zeolite molecular sieve adsorption bed. Due to the adsorption capacity of the zeolite molecular sieve, organic waste gas molecules are adsorbed onto the zeolite rotor and retained for a specified residence time, thereby achieving the removal of organic compounds. In the regeneration zone, the rotor enters the regeneration area, where the organic compounds adsorbed on the rotor are desorbed from the zeolite under the action of hot air. The desorbed organics are then conveyed to the desorption system for further treatment, completing the regeneration process. Following cooling, the rotor can resume adsorption. As the rotor continuously rotates, the cycles of adsorption, desorption, and cooling repeat in sequence, ensuring the continuous and stable operation of the waste gas treatment system.
Uses
1. Suitable for the treatment of large-volume, low-concentration, multi-component organic waste gases.
2. Capable of treating benzene, ketone, alcohol, alkane, and other organic waste gases.
3. Suitable for the purification of various volatile or leaking harmful organic exhaust gases in industries such as automotive, machinery, electronics, electrical appliances, coating, chemical, and pharmaceutical.
Performance Features
1. High performance, high efficiency
Using hydrophobic molecular sieves with exceptional adsorption capacity as the adsorbent can deliver sufficient performance across a wide range of VOC types and under various operating conditions.
2. Treatment of High-Boiling-Point Solvents
By employing hydrophobic molecular sieves, which are non-combustible and exhibit excellent thermal stability, regeneration can be carried out under high-temperature conditions. Consequently, even high-boiling-point VOCs that cannot be treated with activated carbon due to its limited regeneration temperature can be effectively handled.
3. Inertness
Even highly thermally polymerizable VOCs, such as styrene and cyclopropanone, can be efficiently treated using hydrophobic molecular sieves.
4. Cleaning and Activation
The zeolite rotor in the heart of the system is sintered at high temperature, forming a fully inorganic composite; therefore, if the honeycomb channels become blocked, they can be cleaned by water washing. Furthermore, when the molecular sieve has adsorbed impurities that are difficult to desorb, it can be thermally activated at elevated temperatures as needed.
5. Low bed resistance and long service life
The zeolite rotor has a service life of over 10 years, while the main equipment boasts a service life of more than 20 years.
6. Convenient operation with fully automatic control during operation.
7. The equipment is equipped with an intelligent control system, ensuring safe and reliable operation, and includes over-temperature and over-pressure alarm devices.
