This system is ideal for purifying large-volume, low-concentration exhaust gas, whether intermittent or continuous. It accommodates inlet exhaust concentrations up to ≤600 mg/m³, with adjustable CO desorption regeneration frequency based on load. Secondary waste heat recovery enhances energy efficiency.
Technical Principle
The device operates in two stages: adsorption and regeneration.
1.Adsorption Process
Organic waste gas passes through the adsorption bed, where organic components are trapped in the micropores of the adsorption material, separating them from the remaining clean gas, which is discharged by a fan.
2.Regeneration Process
Once the adsorption material is saturated, hot air desorbs the trapped organics, concentrating the gas 10-20 times by controlling the flow rate. The desorbed gas is heated to 250-350ºC by the built-in electric heater. Catalytic oxidation then converts the organics into CO and HO with over 95% efficiency, releasing heat. This heat is reused for desorption and system operations. When organic gas concentrations exceed 2000 PPM, the system achieves thermal balance, requiring no additional energy for continued operation.
3.High-Temperature Regeneration
Zeolite, with a heat resistance of up to 600ºC, undergoes deep desorption at temperatures above 450ºC, ensuring long-term durability and a lifespan of over 5 years.
Product Feature
Features And Advances
1. Fixed adsorption bed can choose a variety of adsorption materials: Honeycomb zeolite, granular zeolite, granular carbon, honeycomb carbon for different exhaust gas conditions.
2. Zeolite material can be regenerated at high temperature: For some easy self-polymerization and high-boiling substances, it can be regenerated at high temperature above 400ºC.
3. Safe and reliable combustion of no open flame: Electric heating tube is used for CO catalytic combustion heating, and flame arrester is set at the inlet and outlet of the equipment.
4. Low combustion temperature, energy saving and consumption reduction: Can save 90% of resources, save 2/3 of energy consumption.
5. High purification efficiency Standard emission: Catalytic combustion purification efficiency of more than 95%, suitable for all kinds of organic waste gas.
6. Less secondary pollution less NOx: Low temperature combustion does not produce NOx, and CO2 and H2O are generated after oxidation.
