Product Overview

Organic gas adsorption desorption concentration. Catalytic purification machinery are our company accumulated years of waste gas treatment experience, developed a successful series of high-efficiency energy-saving products. Through many clients use and confirmed to reach a more advanced level. the machinery are designed according to the two basic principles of adsorption (high efficiency) and catalytic combustion (energy saving). The machinery have two gas paths to work continuously, one catalytic combustion chamber, and two or more adsorption beds are used alternately. The organic waste gas was first adsorbed by activated carbon, then stopped when it reached saturation, then the organic matter was desorbed from the activated carbon by hot gas flow to regenerate the activated carbon; the desorbed organic matter had been concentrated (more than ten times higher than the original concentration) and sent to the catalytic combustion chamber for catalytic combustion into carbon dioxide and water vapor discharge. when the concentration of organic waste gas reaches more than 2000 PPm, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating. part of the exhaust gas after combustion is discharged into the atmosphere, most of which are sent to adsorption beds for activated carbon regeneration. This can satisfy the heat energy needed for combustion and desorption, and achieve the purpose of energy saving. The regenerated activated carbon can enter the next adsorption; during desorption, the purification operation can be carried out by another adsorption bed, which is suitable for both continuous operation and intermittent operation.

Active Carbon Adsorption System:

Active Carbon Adsorption: The core part of the whole machinery, Purification of organic waste gas by self-adsorption
Adsorption Fan: The machinery are operated under negative pressure by using the rear air induced type.
Over-temperature Alarm System: ensure the safe operation of the whole system during desorption of activated carbon;
Thermocouple: Measurement of Carbon Layer Temperature in Desorption by stainless steel protective tube;
Wind Control Valve: Adopt electric valve, electric actuator for high quality brand;
Control system: Full sets system adopts plc control, safe and reliable;

Catalytic Purification Desorption System:

Flame Arrester: It is one of the safety devices of this purifying device, which is composed of the characteristic multilayer metal net, which can prevent the flame from passing through and filter out the larger particles (dirt) in the gas.
Heat Exchanger: winged heat transfer structure, its function is to use the heat released from the catalytic reaction to heat the imported exhaust gas, improve the utilization rate of heat energy, and reduce the heating electric energy.
Hot Resistance: The inlet heating temperature and purification temperature are measured by stainless steel protective pipe.
Catalyst Bed: composed of multi-layer honeycomb catalyst, which is the core of this device.
Explosion-proof Device: this are diaphragm pressure relief mode, when the equipment operation is abnormal, can crack the pressure relief in time to prevent accidents.
Desorption Fan: This device is operated under negative pressure by using the rear air induced type.

Catalytic Combustion Bed:

catalytic combustion is a purification method that uses catalyst to oxidize and decompose combustible components in harmful gases at lower temperature. for hc and organic solvents vapor oxidizes decomposition to produce carbon dioxide and water and releases heat.
It is necessary to mix the harmful gas to be purified and preheat it to the ignition temperature required by the catalyst, so that the combustible group in the harmful gas can be oxidized and exothermic separately.

Product Characteristics:

The design principle of the equipment is advanced, the material is unique, the performance is stable, the structure is simple, the safety no secondary pollution. The equipment covers a small area and is light in weight. The adsorption bed adopts drawer type structure, easy to fill and easy to replace.
Use new type of activated carbon adsorption material - honeycomb-shaped block activated carbon, it is used in large air volume.
the catalytic combustor adopts noble metal catalyst with honeycomb ceramic shape as the support, which has low resistance and high activity. can maintain nature when the concentration of organic waste gas reaches more than 2000 mg/h.
the activated carbon bed for adsorption of organic waste gasorbed and regenerated with hot air after catalytic combustion, and the gas after desorption is sent to the catalytic combustion chamber for purification without external energy, and the operation cost is low, and the energy saving effect is remarkable.

safety design: before and after the catalytic purification device has the fire resistance dust removal system, the equipment top has the pressure relief system.
both inside and outside the equipment are equipped with electrostatic device, high-altitude pipeline with lightning protection device.
the equipment is equipped with multi-point temperature control points, at the same time, it is equipped with automatic alarm system and overtemperature automatic cooling system.
the equipment is equipped with fan overload protection, overtemperature protection, fire prevention chain protection, and safety fire prevention valve is installed at the inlet of the equipment. When high temperature occurs, the fire prevention valve opens automatically.
when desorption occurs when the control and monitoring system is wrong or malfunction, the temperature controller will alarm automatically stop heating, and the cooling system will automatically open, when the desorption fan operation suddenly malfunction, heating system and fan linkage, heating will automatically stop, and the cooling system will automatically open, and start the straight row system.
97% ammonia gas was injected in the middle of the desorption process, and 97% ammonia gas was injected into the activated carbon adsorption bed after the desorption procedure was completed, so as to eliminate the hidden danger of safety caused by the heat storage and spontaneous combustion of the activated carbon itself.

Application Area:

Mainly used for painting, printing, mechanical and electrical, household appliances, shoes, plastics and various chemical workshop volatilization or leakage of harmful organic waste gas purification and odor elimination, suitable for lower concentrations, not suitable for direct combustion or catalytic combustion and adsorption recovery treatment of organic waste gas, especially for the treatment of large air volume, can obtain satisfactory economic and environmental benefits.
