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.gold adsorption on activated carbon  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 www.chinactivecarbon.com

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. If the gas speed is very small, the size of the adsorber is large and uneconomical.www.powdered-activated-carbon.com  If the gas velocity is too large, the pressure drop will increase and the adsorption efficiency will be affected.The optimum gas velocity was determined by experiment.activated carbon pellets wholesale  The adsorption design can not pursue too high adsorption efficiency, the empty tower speed value is reduced, it will make the adsorption bed volume, the amount of adsorbent and equipment cost increased greatly;On the contrary, it is not appropriate to take too large empty tower gas speed. Although the equipment cost is low, the adsorption efficiency drops a lot, and the pressure drop of the system will rise rapidly with the increase of the empty tower speed, resulting in excessive power consumption. Therefore, due to the selection of the appropriate air speed of the empty tower, the most suitable air speed of the empty tower is 0.8~1.2m/s"21, according to the empirical conclusion, this design determines Air velocity of empty tower :U= 1.0m /s.Original conditions:Treatment air volume :Q=20000 m'h, design temperature is 35° C, pressure is 1.01325×103Pa Since the proportion of air in exhaust gas is far greater than that of pollutants, the properties of exhaust gas can be approximately viewed as the thermophysical properties of dry air. Please refer to Appendix 9 of Principles of Chemistry to obtain the following data:Properties of air mixture:Fluid density P;=1.147kg/ m', viscosity u,= 1.94×10-5 Pa.S, specific heat capacity C,=1.005kJ/(kg."C)

The capillary has very strong adsorption capacity, due to the granular surface area is large, so a good contact with with gas (impurities). When these gases (impurities) encounter capillary by adsorption, purification effect. Activated carbon surface area of the study is very important, only the BET specific surface area detecting data of active carbon method detected result is reliable, domestic at present there are many instruments can only make direct comparison method of detection, Plant waste is mostly made of plant fiber raw materials, in the plant body under the action of capillary, modified solution absorbed by material whole fully, between fiber is filled with the subtle space, make the dry material volume expansion after soaking wet, and reaction. Because of the water in the raw material, modified solution constitute a polar molecule, with a strong absorption of microwave dielectric properties,Therefore, polar molecules collide and rub violently with microwave frequency, generating a large amount of heat, which makes water and modified solution volatilize rapidly, and generate steam pressure, which explodes out from the inside of the raw material to the outside. This sharp action makes the fiber space of the raw material expand and produce sharp drying.In this way, the raw material has a more obvious pore structure and a larger internal specific surface area than before microwave irradiation. Compared with the traditional heating method, the mechanism of microwave in the preparation process of activated carbon is completely different.It shows its unique advantages: high efficiency, energy saving, uniformity, selectivity, low pollution, high thermal efficiency, low energy consumption, simple process and equipment and small footprint, conducive to automation, low carbon loss, and recovery of useful substances. https://www.activated-carbon-pellets.com
