Zeolite Rotor
 

Zeolite Rotor Briefing

 
 
 
 

       The zeolite rotor is to condense high-volume and low-concentration exhaust gas to high-concentration and small-volume exhaust gas, thereby reducing the equipment investment and operating cost, and improving the efficient treatment of voc exhaust gas. When dealing with the combustion and recovery of high-volume, low-concentration exhaust gas, if there is no zeolite rotor and the combustion is performed directly, the exhaust gas treatment equipment will not only be bulky, but also the operating costs will be huge.
      The zeolite rotor adsorption and concentration device adopts three continuous procedures of adsorption-desorption-concentration incineration, which is mainly used for the treatment of vocs; it is especially suitable for high air volume and low concentration occasions. The adsorption device is made of ceramic fiber as a base material, and is made into a honeycomb-shaped large disc wheel system. The surface of the wheel is coated with a hydrophobic zeolite powder as an adsorbent. The zeolite rotor adsorption and concentration device is mainly composed of exhaust gas pre-treatment system, molecular sieve rotor concentration adsorption system, desorption system, cooling and drying system, and automatic control system. After the runner, there is usually a post-treatment system. our  process is zeolite rotor + RCO, zeolite rotor + RTO.

How zeolite rotor works?

 
 
 
 
   
       The main structure of the zeolite rotor is a rotating wheel filled with an adsorbent, which is divided into three regions, namely an adsorption region, a regeneration region, and a cooling region. The vocs is introduced into the adsorption area through a blower, and the vocs pollutants therein are adsorbed, and the exhaust gas is purified and discharged. Subsequently, the adsorbent was rotated to the regeneration-zone, and during contact with the high-temperature air, VOCS was desorbed and flowed out with the regeneration air, and the adsorbent was regenerated. The regenerated adsorbent is first cooled through the cooling zone, and then rotated to the adsorption zone to re-adsorb. As the rotor  rotates, the adsorbent periodically adsorbs, desorbs, and cools to achieve purification of organic waste gas.

 Step 1: adsorption and concentration
        The exhaust gas is adsorbed by the zeolite in the rotor, and the cleaned exhaust gas is exhausted into the atmosphere by a system extraction frequency conversion fan; the adsorber can provide a huge zeolite surface area to contact the vocs, and the rotor continues to rotate at a speed of 1 to 6 revolutions per minute.
Step 2: Desorption
        The VOCs in the rotor are concentrated into a saturated zeolite zone, and the heat flow (about 200 ° C) provided by the heat exchanger is used for desorption. After the desorption is completed, it is rotated to the cooling zone, cooled by normal temperature air blow to normal temperature and then rotated to adsorption Concentrated area.

>> Advantages of zeolite rotor equipment
     ① The rotor has a high concentration ratio, and the concentration ratio is as high as 20: 1, so that the original high-volume and low-concentration VOCs exhaust gas is converted into low-air-volume and high-concentration exhaust gas
     ② The rotor has a long service life, and there is no need to periodically replace the adsorption material;
     ③ The system is automatically controlled with a high degree of automation, one-button startup, simple operation, and can monitor important operating data with the man-machine interface;
     ④Simple operation, safe and reliable operation, the overall system adopts a modular design, has the minimum space requirements, and provides a continuous and unmanned control mode;
     ⑤ The natural zeolite has superior performance in adsorbing and concentrating aromatic waste gas;
     ⑥ Can handle exhaust gas with relatively high relative humidity;
     ⑦The pressure drop generated by the adsorption of VOCs by the  zeolite rotor can greatly reduce the power consumption and lower the operating cost.
 
>> Advantages of Baolan adsorption material
     1. The main material of honeycomb molecular sieve is natural zeolite, which is an inorganic microporous material composed of SiO2, Al2O3 and alkaline metal or alkaline earth metal;
     2, with uniform micropores, the pore size is equivalent to the general molecular size, the internal pore volume accounts for 40-50% of the total volume, and the specific surface area of ??300-1000 m2 / g;
     3. Due to the uniform pore size distribution, the structure and composition change obviously, and it has the characteristics of high temperature resistance, non-combustibility, good thermal stability and hydrothermal stability.
