Molecular sieve adsorption concentration wheel

The Napotec® molecular sieve adsorption concentration rotor (ZCR - Zeolite Concentrator Rotor) is developed and manufactured by Qingdao Nabok Environmental Technology Co., Ltd. It is one of the earliest manufacturers in China to research and develop molecular sieve adsorption concentration rotors. It attaches high-silicon-aluminum ratio hydrophobic molecular sieves onto honeycomb-shaped porous carriers to form a continuous rotating adsorption device. 

The rotor is divided into three zones: adsorption, desorption, and cooling. For large volume and low concentration VOCs waste gas, it is precisely adsorbed by the molecular sieve when passing through the adsorption zone, and the purified gas is discharged in compliance with standards. When the adsorption saturation zone is reached, it moves to the desorption zone. A small amount of high-temperature hot air (about 180-220℃) is used to desorb, forming a small volume and high concentration waste gas, which is sent to RTO, CO and other downstream devices for treatment. After cooling in the cooling zone, it is recycled, and the three zones operate synchronously and continuously. 

This product is specifically designed for large volume and low concentration organic waste gas. After concentration, it significantly reduces the investment and operating costs of the downstream equipment. The hydrophobic molecular sieve still has stable adsorption capacity under high humidity conditions. The inorganic material is resistant to high temperatures and not flammable, and its safety is superior to the activated carbon device. It is widely used in waste gas treatment in industries such as painting, printing, chemical, and petrochemical.
