Introduction to zeolite molecular sieve adsorption desorption catalytic combustion integrated machine equipment

Product introduction: The equipment is mainly used for VOCs exhaust gas treatment. The exhaust gas is first pretreated by a dry filter to remove particulate matter from the exhaust gas, ensuring the efficient operation of the zeolite molecular sieve adsorption process; After entering the zeolite molecular sieve, VOCs pollutants are adsorbed on the zeolite molecular sieve;

The second stage of desorption process is to heat exchange the waste gas from the cooling zone to about 180-220 ℃, and then pass it into a molecular sieve to desorb organic matter at high temperature. The desorbed high concentration waste gas enters the catalytic device for low-temperature combustion treatment, where VOCs are oxidized into H2O and CO2, and the waste gas is purified.

Application scope: Applicable organic waste gas types: alkanes, alkenes, alcohols, ketones, ethers, esters, aromatic hydrocarbons, benzene and other hydrocarbon organic waste gases.
Low concentration of organic matter (while meeting the requirement of less than 25% LFL) and high air volume.
The exhaust gas contains multiple organic components, or the organic components often change.
Waste gas containing components that can easily cause catalyst poisoning or activity degradation.

Performance advantages: The use of PLC control system realizes the automation of purification and desorption processes, ensuring safe, stable and reliable operation. Low equipment investment and operating costs;
The use of "zeolite" adsorbent material avoids the risk of fire caused by using activated carbon as adsorbent material. During desorption, higher temperature hot air can be used to desorb large organic molecules on the adsorbent material, ensuring the regeneration efficiency of the adsorbent material. The service life has been significantly improved.
The equipment has a small footprint and light weight. The adsorption bed filter material adopts a stacked structure, which is easy to load and replace; High quality precious metals palladium and platinum are used as catalysts on honeycomb ceramics, which have low resistance, high activity, long service life, and excellent performance

The characteristics include low desorption temperature, short desorption preheating time, low energy consumption, and good stability.
Utilize waste heat to save energy. The desorption and desorption of this system all use hot air as the desorption medium, and this hot air flow mainly comes from the residual heat after catalytic combustion in the system. When the concentrated organic waste gas after desorption cannot reach the ignition temperature after heat exchange and heating, electric heating is only used as a supplement. When it reaches the ignition temperature, it enters the catalytic burner for purification treatment, greatly reducing operating costs.
The adsorbent adopts zeolite molecular sieve, with high desorption temperature, good desorption effect, and long service life. No secondary pollution.
The system has low power consumption, with only the power consumption of the adsorption fan during the adsorption process. In the initial stage of the desorption process, electric heating is used. After reaching the catalytic reaction temperature, the heat released from combustion can be increased through a heat exchanger, which can reduce the power consumption of electric heating.

Process route:

The process route should be selected based on a comprehensive analysis of factors such as the source, properties (temperature, pressure, composition), and flow rate of the exhaust gas.
