Napotec® molecular sieve rotor exhibits its attractive appearance at the 17th Circular Industry Expo

On May 5, 2016, the 17th Environmental Expo of China was successfully held in Shanghai. Qingdao Naboko introduced the giant "rotating wheel" which attracted widespread attention. This giant rotating wheel, approximately 2 meters high and 2 meters long, is called "Molecular Sieve Adsorption Concentration Wheel". It is the first batch of patented products obtained by Qingdao Naboko Environmental Technology Co., Ltd. in China and is currently the only environmental enterprise in China with the ability to produce it in large quantities.

The principle of the "Molecular Sieve Adsorption Concentration Wheel" is to adsorb and concentrate industrial waste gas with "high volume and low concentration". Naboko's Napotec® molecular sieve rotating wheel has ten types of models, ranging from 800mm to 4800mm, with different effects. The larger the diameter, the greater the production difficulty. The core adsorption material of the molecular sieve rotating wheel is composed of zeolite, with strong adsorption capacity for industrial waste gas. The production process requires strict requirements.

The adsorption characteristics of Napotec® molecular sieve rotating wheel:

1. Strong adsorption selectivity

The pore size is uniform and regular, and it is an ionic adsorbent that can selectively adsorb based on the size and polarity of molecules.

2. Hydrophobic property

The hydrophobic molecular sieve with a high Si/Al ratio does not adsorb water molecules in the air and selectively adsorbs VOCs.

3. Strong adsorption capacity

The adsorption capacity is large, and the single-stage adsorption efficiency can reach 90-98%. It still has strong adsorption capacity at a higher temperature.

4. High temperature resistance, non-flammable property

It has good stability, with a de-adsorption temperature of 180-220 degrees, and the heat resistance temperature during use can reach 350 degrees. The de-adsorption is thorough, and the VOCs concentration ratio can reach 5-30 times.

The working principle of the molecular sieve rotating wheel:

1. Effective partition

The molecular sieve concentration rotating wheel is divided into the adsorption zone, the de-adsorption zone, the cooling zone, and the rotating wheel continuously operates in each zone.

2. High-temperature de-adsorption

After the molecular sieve is saturated in adsorption, it enters the de-adsorption zone and undergoes de-adsorption and concentration (with different concentration ratios depending on the working conditions).

3. Cooling regeneration

The area after high-temperature de-adsorption is cooled by cold air, and the air used for cooling can be used as regeneration air after heating.

4. Purification and discharge

VOCs waste gas is pre-treated by filters and other devices, and then enters the rotating wheel adsorption zone for adsorption and purification before being discharged.

The main manufacturers in the world that can produce molecular sieve zeolite rotating wheels are mainly foreign enterprises. After years of research and development, Naboko Environmental Technology Co., Ltd. has successfully applied it to dozens of enterprises and achieved mass production, which can provide this product to many domestic environmental enterprises and engineering companies. In the bidding process for environmental equipment by enterprises, it is listed as the designated product for adsorption concentration with foreign enterprises.
