GADW Granular Activated Carbon Cleaning, Desorption, and Regeneration System
A multi-process, single-tank, centralized granular adsorbent regeneration unit typically refers to a piece of equipment used in the treatment of exhaust air under various operating conditions, where the adsorbent is transferred to a centralized location for regeneration once it reaches adsorption saturation. During use, granular adsorbents not only adsorb VOCs from exhaust air but also adsorb particulate pollutants to varying degrees on their surfaces (in most cases involving particulate-laden exhaust air treatment), which ultimately affects the adsorption efficiency of the granular adsorbent. In such cases, high-temperature desorption alone is insufficient to efficiently regenerate the granular adsorbent; therefore, processes such as washing and decontamination prior to desorption are particularly important. Granular activated carbon is loaded from the top and unloaded from the bottom. After washing and decontamination, desorption and regeneration can be achieved through catalytic combustion or thermal combustion.
MSD Zeolite Rotating Adsorption Bed
Exhaust air containing volatile organic compounds (VOCs) passes through a filter to remove particulate matter and then enters the adsorption zone of the zeolite rotor. The zeolite on the rotor has a highly porous structure capable of adsorbing VOCs from the exhaust air. Once adsorption is saturated, a drive motor rotates the zeolite rotor to the desorption zone, where hot air or other regeneration media is used to desorb the VOCs adsorbed onto the zeolite, forming a high-concentration exhaust air stream for subsequent treatment, such as combustion or condensation. After cooling following desorption, the zeolite rotor returns to the adsorption zone to continue adsorbing VOCs from the exhaust air.
ZDS Zeolite Honeycomb Adsorption Bed
ZDS Zeolite Honeycomb Adsorption Bed is an environmental protection device that utilizes the adsorption properties of zeolite to treat gaseous pollutants. It employs zeolite material with a honeycomb structure; the zeolite consists of numerous small honeycomb cells, which facilitate the uniform distribution of gas within the bed and enhance adsorption efficiency. As a silicoaluminate mineral with a microporous structure, zeolite has a high specific surface area and strong selective adsorption capacity, making it suitable for adsorbing organic compounds and certain inorganic compounds from gases. During operation, the gas containing pollutants passes through the adsorption bed, where the pollutant molecules are captured and adsorbed by the zeolite’s micropores to purify the gas. As adsorption proceeds, the zeolite honeycomb units gradually become saturated; at this point, methods such as thermal regeneration are required to restore their adsorption capacity. During thermal regeneration, the saturated units are heated, causing the contaminants to desorb into the gas stream, where they are captured and treated by downstream equipment. Once thermal regeneration is complete, the thoroughly desorbed units are cooled to room temperature and can then be put back into service for adsorption.
Regenerative Catalytic Oxidizer(RCO)
Exhaust air containing volatile organic compounds (VOCs) first undergoes pretreatment to remove particulate matter and impurities, and then enters the preheating chamber. In the preheating chamber, the exhaust air is heated to a certain temperature, typically between 200°C and 400°C. Next, the preheated exhaust air enters the catalytic combustion chamber, where, under the action of a catalyst, the VOCs undergo an oxidation reaction with oxygen to form carbon dioxide and water, releasing a large amount of heat. The high-temperature gas produced by the catalytic combustion reaction passes through a heat exchanger, where it exchanges heat with the exhaust air entering the preheating chamber. This process lowers the temperature of the high-temperature gas while heating the exhaust air to the temperature required for the reaction. In this way, heat is recovered and reused, thereby reducing the equipment’s operating costs.
Regenerative Thermal Oxidizer（RTO）
Regenerative Thermal Oxidizer（RTO） is a highly efficient system for treating organic exhaust air. During operation, the organic exhaust air first enter a heat exchanger, where they are heated to approximately 800°C through heat exchange, preparing them for the subsequent thorough oxidation and decomposition of volatile organic compounds (VOCs). Next, the preheated exhaust air enters the combustion chamber, where, at temperatures above 800°C, the VOCs are oxidized and decomposed into carbon dioxide and water. The heat generated during this reaction maintains the temperature of the catalytic bed at 800–900°C, facilitating the decomposition of most VOCs. Subsequently, the purified gas passes through the heat exchanger again to recover heat and reduce the temperature of the exhaust air. The heat generated during the oxidation process is stored in specially designed ceramic heat storage media. These media are typically divided into two or more compartments, each of which sequentially undergoes heat storage, heat release, and purging cycles. This cyclic operation is used to preheat the incoming organic exhaust air, thereby effectively reducing fuel consumption required to raise the exhaust air temperature.
Multi-stage Condensation Recovery Equipment
System Configuration: First-stage gas-water finned-tube condenser + high-boiling-point oil scrubber + second-stage finned-tube chilled-water condenser (chiller) + electrostatic precipitator (with a shared automatic electric-heated spray cleaning system), skid-mounted unit, with a shared cooling tower as an external component. The multi-stage condensation and recovery equipment comprises a purification unit, a water-cooling unit, and a water-washing unit; these three units form an integrated process. The purification unit condenses high-temperature oil vapors, oil mist, and oil fumes through two-stage condensation, single-stage oil washing, and electrostatic precipitation, and discharges the purified emissions in compliance with standards. The water-cooling unit supplies low-temperature chilled water to the two-stage condensation process. The water-washing unit performs offline automatic cleaning of the finned tubes inside the condensation tower and the electrostatic fields within the electrostatic precipitator.
The zeolite rotor production line precisely controls core processes such as coating, impregnation, and calcination. By implementing a digital manufacturing information system (MES), it enables automated control of key processes—including calcination, slitting, and polishing—as well as end-to-end data traceability. Our proprietary molecular sieve formulation and high-temperature calcination technology for green bodies ensure the rotors maintain structural stability and resist powder shedding during long-term operation. The unique pore channel design enables our products to achieve a specific surface area comparable to that of high-end imported rotors under the same loading conditions. Currently, we offer a full range of products with diameters ranging from 800 mm to 4,800 mm, as well as custom green bodies, and have successfully launched specialized rotors designed for complex components such as styrene and methanol.
Wire mesh demisters are used to separate liquid droplets entrained in gas streams to ensure mass transfer efficiency, reduce the loss of valuable materials, prevent clogging of outlet pipelines, avoid compromising subsequent processes, and improve the operation of downstream compressors. Rising droplets collide with the wire mesh due to inertia and are intercepted by it; they then fall under their own weight, diffuse across the surface of the fine wires, and finally coalesce into larger droplets at the mesh junctions before falling back into the equipment. After passing through the wire mesh demister, the gas is essentially free of mist.
