ONE:Overview
Zeolite runner adsorption concentration purification device (LZX) is an energy-saving and non-secondary pollution purification device applied to the treatment of large air volume and low concentration organic gas on the basis of the introduction of foreign equipment and technology. The comprehensive operating cost is low, and it is one of the more advanced devices for treating low-concentration waste gas at present.

The zeolite rotor adsorption and concentration device adopts three continuous procedures of adsorption-concentration-desorption incineration, which is mainly used for the treatment of organic waste gas; it is especially suitable for large air volume and low concentration occasions. The adsorption device uses ceramic fiber as the base material, and is made into a honeycomb-shaped large disc wheel-shaped system, and the surface is coated with hydrophobic zeolite as an adsorbent. The zeolite runner adsorption and concentration device is mainly composed of waste gas pretreatment system, zeolite runner concentration and adsorption system, desorption system, cooling and drying system and automatic control system.

TWO:Scope of application
       1. Exhaust treatment of various painting workshops (automobile manufacturing, shipbuilding, aircraft manufacturing, steel products, resin products, etc.);
       2. Exhaust treatment of various printing workshops (gravure printing, printing of building and decoration materials, and various other printing processes);
       3. Exhaust treatment of dry laminated paper products and coating processes;
       4. Exhaust treatment in the manufacturing process of semiconductor integrated circuits;
       5. Exhaust treatment of liquid crystal display (LED) manufacturing process;

       6. Exhaust treatment in the process of lithium ion battery manufacturing (electrode formation process, electrolyte filling process).

THREE. Working principle
The concentration runner area is divided into a treatment area, a regeneration area and a cooling area, and the concentration runner operates continuously in each area.
The treated air containing VOC is sent to the treatment area of ​​the concentration runner after being pre-filtered. In the treatment area, VOC is adsorbed and removed by the adsorbent, and the air is purified and discharged from the treatment area of ​​the concentration runner.
The VOC adsorbed in the concentration runner is desorbed and concentrated (5~15 times) by hot air treatment in the regeneration zone.

The concentration runner is cooled in the cooling zone, and the air passing through the cooling zone is heated and used as regeneration air to achieve the effect of energy saving.

FOUR: Structural characteristics
       1. High adsorption and desorption efficiency;
       2. The pressure drop generated by the adsorption of VOCs by the runner reduces power consumption;
       3. Convert the original high-volume, low-concentration VOCs waste gas into low-volume, high-concentration waste gas, with a concentration ratio of 5-15 times, reducing the specifications of post-processing equipment and lowering operating costs;
       4. The overall system adopts a modular design, which requires less space and provides a continuous and unmanned control mode;


       5. The system is automatically controlled, one-button start, simple operation, and can be used with human-machine interface to monitor important operating data.
