Its adsorption performance mainly depends on several main material parameters and process parameters on it [8. Material parameters including carbon adsorption porosity, thickness of honeycomb structure and the content of carbon; process parameters including fluid flow rate and concentration of the adsorption properties of adsorption, can adsorption depends on the carbon structure and adsorption properties of features such as molecular weight). The curve is one of the main performance characterization of adsorption, adsorption is the adsorbate concentration ratio before and after the change over time of a function [9 '. This ratio is 0.95, the amount of adsorption properties of adsorption is called penetration capacity. Penetration capacity depending on the fluid flow rate, the concentration of the adsorbate and honeycomb carbon component content  Factors such as [10. For honeycomb activated carbon, the wall thickness is a very important parameter, by changing the wall thickness to improve its adsorption efficiency. Under the same porosity, thickness increases, the honeycomb carbon content per unit volume also will increase, which can improve the adsorption capacity. This is because the wall thickness increases, the fluid channel in the cellular cross-sectional area reduced, so the real surface or volume flow rate will increase. At the same time, the contact between adsorbate and carbon efficiency will, there is a balance between the two. Under the given conditions, the balance will determine adsorption increase or decrease. If the adsorbate at higherthe diffusion rate diffuses to the inside of the honeycomb wall, and the empty adsorption site can be continuously adsorbed, so the thick-walled honeycomb should have better adsorption efficiency and adsorption capacity"Determination of air velocity and cross-sectional area of empty towerThe empty tower gas velocity is the velocity of gas passing through the entire cross section of the adsorber.The selection of air velocity not only directly determines the size and pressure drop of the adsorber, but also affects the adsorption efficiency. activated carbon pellets wholesale

Organic waste gas comes from a variety of sources, and its generation and emission methods are not the same.Therefore, the treatment technology of organic waste gas is also varied, and each treatment technology also has its own different advantages and  In the actual production process, according to different conditions, the choice of appropriate methods is the key to organic waste gas treatment.imagitarium activated carbon pellets   The treatment of organic waste gas mainly includes two categories: recovery method and elimination method.The main recovery technologies of organic waste gas include: adsorption method, absorption method, condensation method, membrane separation technology and pressure swing adsorption technology.Organic waste gas elimination technology can be divided into two categories: physical - chemical method and biological method. Physical - chemical methods include thermal destruction, photodecomposition, corona, ozone decomposition, etc.Biological methods include biological filter, biological drip filter, biological scour tower, membrane bioreactor, activated sludge process, etc.The purification rate of activated carbon adsorption method can reach more than 95%, if there is no regeneration device, the operation cost is too high, if the steam recovery, the process is too long, the operation cost is high, the recovery of solvent and water mixture utilization value is not high;Regeneration needs a stable steam source, and the adsorption capacity of activated carbon after repeated adsorption and desorption will gradually reduce, generally use two or three years after the replacement.The purification rate of liquid absorption method is only 60%-80%, and there are secondary pollution problems. The purification rate of catalytic combustion method can reach 95%, but it is suitable for the treatment of high concentration, small air volume and high exhaust gas temperature of organic waste gas, and the gas temperature is higher, in order to improve the exhaust gas temperature, it needs to consume a lot of energy.The most used method is a catalytic combustion method, adsorption, it mainly particles or honeycomb carbon as adsorbent, to ensure the continuity of production, generally set up two adsorption bed used interchangeably, as a result of the 海large investment, operation trouble;As the bed volume is large, it is easy to appear the combustion and explosion caused by the accumulation of adsorption heat.To solve these problems, the adsorber of the existing new device adopts a multi-unit shunt combination structure, and uses a new material -- activated carbon fiber as adsorbent
