(1) The advanced treatment unit, as the core process unit of this technical product, can improve the exhaust gas treatment efficiency to over 99%, and the non-methane total hydrocarbon concentration in the exhaust gas can be stabilized below 50mg/m³ for a long time, and the odor concentration can be stabilized at 200%. (dimensionless) below;

(2) Equipped with a safe and high-strength regeneration unit to ensure the regeneration efficiency of the adsorbent, ensure that the service life of the adsorbent is more than 5 years, and ensure that the exhaust gas reaches the standard stably for a long time.

(3) Equipped with a non-condensable gas reduction unit to process a small amount of non-condensable gas after regeneration. This part of the non-condensable gas can be recovered as light hydrocarbons or sent to the oxidation device for treatment, which is environmentally friendly and reduces secondary pollution.

(4) The chemical pretreatment unit and the biological treatment unit are used as auxiliary means of the products of this technology, mainly for the biochemical treatment of sulfur series, ammonia series, malodorous substances and some soluble VOCs, so as to reduce the processing load of the advanced treatment unit.

(5) This technical product solves the two major pain points in the industry that the adsorption process cannot reach the standard stably for a long time and the adsorbent is easy to fail. Similar to the traditional waste gas adsorption treatment process, our company takes the adsorption performance and service cycle of the adsorbent as the core technical points. Through the high-efficiency adsorbent adsorption and desorption combined process, the processing load of the Waste Gas Treatment system is increased to ensure the stable discharge of waste gas and meet the needs of various waste gas treatment conditions. The flexible combination of other waste gas treatment processes (eg: KG-VRU, KG-RTO, KG-RCO...) makes this technology product more widely applicable.
