Dry adsorption tower

Dry adsorption tower can adsorb and treat difficult gases such as nitrogen oxides, and can purify and treat multiple mixed acid gases simultaneously; High adsorption purification efficiency, good temperature adaptability, and low operating costs.

1. Low operating cost: Due to the absence of a water circulation system, the operating cost is relatively low, and the operation is simple and maintenance free.

2. No secondary pollution: solid adsorbents (such as activated carbon) are used for adsorption, which does not produce wastewater and therefore does not cause secondary pollution. The replaced adsorbent can be treated as harmless waste.

3. Wide applicability: Suitable for various site requirements, flexible design, and can adapt to different waste gas treatment needs.

4. Automated control: It can be equipped with automated control devices, including gas online analyzers, pressure sensors, differential pressure transmitters, flow sensors, and control cabinets, to achieve functions such as online gas analysis and monitoring, automatic alarm for exceeding standards, etc.

5. Easy maintenance: The operation and management are simple, and the adsorbent can be used for about a year after being added at once, with easy replacement.

6. These characteristics make dry adsorption towers have broad application prospects in the field of environmental protection, especially in the treatment of high concentration acidic waste gas.

2、 Principle of Physical Adsorption

This mainly occurs during the process of removing impurities from liquid and gas phases using activated carbon. The porous structure of activated carbon provides a large surface area, making it very easy to achieve the purpose of absorbing and collecting impurities. Just like magnetism, all molecules have mutual attraction. Because of this, a large number of molecules on the pore walls of activated carbon can generate strong attraction, thereby achieving the goal of attracting impurities from the medium into the pore size. It must be pointed out that the molecular diameter of these adsorbed impurities must be smaller than the pore size of activated carbon in order to ensure that the impurities are absorbed into the pore size. That's why we create activated carbon with different pore structures by constantly changing raw materials and activation conditions, making it suitable for various impurity absorption applications.
