Composition and characteristics of exhaust gas

During the daily operation of the laboratory, corresponding exhaust gases are generated. If they are directly discharged into the atmosphere without treatment, it will inevitably cause pollution to the surrounding environment and organic damage to human health. The inorganic and organic waste gases contained in the exhaust gas.

Design principles

Implement relevant national environmental protection policies, regulations, norms, and standards.

The operation of the exhaust gas treatment engineering system is stable and reliable.

Adopting mature technology, advanced processes, and easy to operate and manage processing techniques, system operation and management And it is easy to maintain, with low engineering investment and low operating costs.

The equipment selected in the processing technology should be compatible with the existing equipment in the laboratory and should not affect the current status of the laboratory Normal operation of equipment, taking into account existing facilities, adapting to local conditions, and reducing investment costs.

Process selection

By using activated carbon adsorption method, its absorption efficiency can reach up toMore than 90%.

Principle of Activated Carbon Adsorption

Activated carbon is a type of microcrystalline carbon material mainly made of carbon containing materials, with a black appearance, developed internal void structure, large specific surface area, and strong adsorption capacity. There are numerous micropores in activated carbon materials that are not visible to the naked eye,The micropores in 1 gram of activated carbon material can have a surface area of up to 800-1500 square meters when unfolded, with some even higher. That is to say, in a rice sized activated carbon particle, the internal surface area of the micropores may be equivalent to the size of a living room. It is precisely these highly developed, human like porous structures that endow activated carbon with excellent adsorption performance.

The force of mutual adsorption between molecules isVan der Waals forces. Although the speed of molecular motion is affected by factors such as temperature and material, it always moves continuously in the microenvironment. Due to the mutual attraction force between molecules, when a molecule is captured by the pores of activated carbon and enters the voids inside the activated carbon, the mutual attraction between molecules will cause more molecules to be continuously attracted until the voids inside the activated carbon are filled.

Activated carbon desorption method

When the internal voids of activated carbon are filled with organic waste gas, i.e. adsorbed substances, and reach saturation, pollutants begin to be released, and this phenomenon is called penetration. The activated carbon adsorption bed that has reached saturation needs to be regenerated. Generally, heated gas is used to desorb the adsorption bed, which not only makes the regeneration of the adsorption bed active again, but also releases pollutants for recovery or decomposition treatment. This detachment method is called temperature desorption. The adsorption capacity of a substance decreases with increasing temperature. Increasing the temperature of the adsorbent can cause the adsorbed components to desorb. This method is also known as temperature dependent desorption, and the temperature throughout the process varies periodically.
