product description


Activated carbon adsorption-desorption purification system is a set of purification system designed based on the two basic principles of adsorption (high efficiency) and catalytic combustion (energy saving), and organically combines the adsorption concentration device and thermal oxidation device. Mainly for large air volume and low concentration of organic waste gas, after adsorption purification and desorption, it is converted into small air volume and high concentration of organic waste gas, and it is thermally oxidized. At the same time, the heat released by the combustion of organic materials is effectively used. The activated carbon bed that adsorbs organic waste gas is desorbed and regenerated with the hot gas after catalytic combustion, and the desorbed gas is sent to the catalytic combustion chamber for purification. It requires no external energy, has low operating costs, and has significant energy saving effects.

working principle


This system generally uses two or three adsorption chambers and a catalytic combustion chamber to ensure continuous system operation. First, the organic waste gas is adsorbed with activated carbon, and the adsorption is stopped when it reaches saturation, and then the organic matter is desorbed from the activated carbon with a hot air stream to regenerate the activated carbon. The desorbed organic matter has been concentrated (the concentration is increased by dozens of times) and It is sent to the catalytic combustion chamber to be burned into carbon dioxide and water vapor under the action of the catalyst. When the organic waste gas reaches a certain concentration, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating. A part of the exhaust gas after combustion is discharged into the atmosphere, and most of it is sent to the adsorption bed for activated carbon regeneration, which can meet the thermal energy required for combustion and adsorption, achieve the purpose of energy saving, and the regeneration can enter the next adsorption. During desorption, the purification operation can be performed with another adsorption bed, which is suitable for both continuous operation and intermittent operation.


Process flow


Application range


Mainly used in: organic waste gas with lower concentration, which is not suitable for direct combustion or catalytic combustion and adsorption recovery treatment, especially high-volume exhaust gas, including paint, rubber, plastic, resin, leather, insulation materials, printing, food and foundry, etc. Purification of organic waste gas in the industry, such as organic mixed gases such as aromatics, aldehydes, esters and alkanes.

The exhaust gas components must not contain the following substances, otherwise it will cause catalyst poisoning, affect the reaction effect and reduce the service life.

1. High viscosity grease;

2.Phosphorus, bismuth, arsenic, antimony, mercury, lead, tin, sulfur, etc .;

3. High concentration of dust;


Features


性能稳定,操作方便,自动化控制。 Stable performance, easy operation and automatic control.

吸附室采用新型蜂窝活性炭,压降小,非常适用于大风量工况,净化效率一般达90%以上。 Adsorption chamber adopts new honeycomb activated carbon with low pressure drop, which is very suitable for large air volume conditions, and the purification efficiency is generally more than 90%.

系统能耗低。 Low system energy consumption. 加热停止,启动电加热时间大约为1小时左右。 Catalytic combustion requires electric heating to start. After the desorption and concentration of the organic waste gas begins to burn in the catalytic bed, its combustion heat is sufficient to maintain the temperature required for its reaction. At this time, the electric heating is stopped and the electric heating time is about 1 hour.

配有阻火系统、防爆泄压系统、超温报警系统等,安全可靠。 Equipped with fire resistance system, explosion-proof pressure relief system, over-temperature alarm system, etc., safe and reliable.

催化燃烧室采用先进的贵金属钯、铂浸渍的蜂窝状陶瓷载体催化剂,比表面积大、阻力小,当有机蒸气达到一定浓度时,可维持自 燃。 ● The catalytic combustion chamber adopts advanced noble metal palladium and platinum impregnated honeycomb ceramic carrier catalyst, which has a large specific surface area and low resistance. When the organic vapor reaches a certain concentration, it can maintain spontaneous combustion .

使用寿命长,运行费用低。 Long service life and low running cost.

可选配数据采集和远程控制功能。 Optional data acquisition and remote control functions.
