Zeolite Rotary Concentration Technology

Utilizes hydrophobic zeolite to adsorb VOCs, achieving continuous adsorption and desorption through a rotating rotor. Large volumes of waste gas are purified in the adsorption zone, while small volumes of hot air concentrate the VOCs in the desorption zone before discharge.

Process

Adsorption: Waste gas passes through most of the rotor area, where VOCs are adsorbed by the zeolite, resulting in clean air discharge.

Desorption: A small stream of hot air passes through a small section of the rotor in the opposite direction, releasing high-concentration VOCs.

Cooling: A small amount of air cools the desorption zone, restoring adsorption capacity.

Treatment: High-concentration waste gas is efficiently treated in a small-scale incineration or recovery unit.

Features

Highly Targeted: Specifically designed for "large volume, low concentration" waste gas, solving the problem of uneconomical treatment methods in industries such as spraying and printing.

Energy-Saving and Highly Efficient: Only a small portion of the concentrated gas requires subsequent high-temperature treatment, and the desorption temperature is relatively low, resulting in overall energy consumption that is 50%-70% lower than direct incineration. 

Stable and Reliable:Utilizing hydrophobic zeolite, it is insensitive to humidity changes, with purification efficiency typically remaining above 90%, ensuring long-term stable emission compliance.

Intrinsically Safe: Zeolite is an inorganic, non-flammable material, and the adsorption and desorption zones are physically isolated, posing no risk of combustion or explosion, making it suitable for explosion-proof environments such as chemical plants.

Application Areas

Zeolite rotary technology is particularly suitable for treating typical waste gases from the following industries:

Surface Coating Industry: Automotive, furniture, and home appliance spraying lines, especially waste gases from drying rooms using solvent-based coatings.

Printing and Packaging Industry: Waste gases generated by printing presses, laminating machines, and coating machines.

Electronics and Semiconductor Industry: Low-concentration organic waste gases generated from processes such as photolithography, cleaning, and resist removal.

Chemical and Pharmaceutical Industry: Breathing waste gases from some workshops and storage tanks.

Others: Food processing, textile finishing, and other applications generating odors and low-concentration VOCs.

Core Role of Honeycomb Ceramics

Bearing Platform: Provides a large, regular surface area to support a sufficient amount of zeolite.

Guaranteed throughput: The honeycomb through-channel design ensures extremely low pressure drop when tens of thousands of cubic meters of exhaust gas pass through.

Stable operation: The high-strength matrix withstands rotating mechanical stress and alternating thermal shocks.

Summary

Zeolite rotor technology solves the problem of low-concentration, high-volume exhaust gas in an economical and efficient manner through a "concentration before treatment" approach. The honeycomb ceramic, as the core framework of the rotor, directly determines the system's efficiency and lifespan. We are a Chinese honeycomb ceramic manufacturer.
