Faced with increasingly stringent national environmental regulations and the inherent demand for green transformation in manufacturing, our company has successfully scaled up the application of its self-developed “Honeycomb Molecular Sieve Adsorption Concentration + Desorption-Regenerative Catalytic Combustion” system. This system provides a “golden key” solution to the industry-wide challenge of treating high-volume, low-concentration VOCs and has demonstrated outstanding performance in multiple key industry applications.

For a long time, VOCs waste gases generated by industries such as automotive coating, furniture spraying, and printing and packaging have generally exhibited characteristics of high volume, low concentration, and complex composition. While traditional activated carbon adsorption technology can handle these gases, it suffers from limitations such as limited adsorption capacity, incomplete desorption, high fire risks, and high solid waste disposal costs.

Our company’s new-generation system revolutionarily adopts “honeycomb molecular sieve” as the adsorption medium. Compared to traditional activated carbon, molecular sieve possesses non-combustible physical properties, fundamentally eliminating the fire hazards during the desorption process. It also allows the system to achieve complete desorption at high temperatures of 180-220°C, effectively removing high-boiling-point organic pollutants with boiling points exceeding 200°C, thus solving the industry pain point of activated carbon easily becoming “poisoned” and deactivated.

During operation, high-volume, low-concentration waste gas first passes through the honeycomb molecular sieve rotor, where VOCs are selectively adsorbed, and the purified gas is directly discharged in compliance with standards. When the saturated adsorption area of the molecular sieve rotates to the desorption zone, a small volume of high-temperature hot air (350-380°C) thoroughly desorbs the adsorbed VOCs, forming a small-volume, high-concentration concentrated gas stream. This concentrated gas then enters the RCO regenerative catalytic oxidizer, where, under the action of precious metal catalysts, it undergoes flameless catalytic combustion at a relatively low temperature of 300-400°C, efficiently decomposing into harmless carbon dioxide and water, with a purification efficiency of over 99%. Meanwhile, the heat released during combustion is recycled for desorption, significantly reducing operational energy consumption.

With its notable advantages of safety, efficiency, and energy savings, this system has become the mainstream choice for end-of-pipe VOCs treatment technologies. Our company will continue to iterate on this technology, contributing more technological power to the “Blue Sky Defense Campaign.”
