The selection of treatment technology should be based on the gas volume, purification requirements, the possibility of recovery, the economy of equipment construction and operation and other conditions. Special attention should be paid to the close cooperation with the process in practical work, so as to achieve comprehensive utilization as far as possible. activated carbon manufacturers  At present, there are three common methods of organic waste gas treatment at home and abroad: liquid absorption method, activated carbon adsorption method and catalytic combustion method. The purification efficiency of liquid absorption method is 60%~ 80%, which is suitable for treating low concentration and large volume of organic waste gas, but there are secondary pollution. The purification rate of catalytic combustion method is 95%, which is suitable for the treatment of high concentration and small air volume organic waste gas. The disadvantage is that it has strict requirements on the treatment object and requires high gas temperature. In order to improve the exhaust gas temperature, it needs to consume a lot of fuel, so the operation cost is very high.dxdcarbon.com  The purification efficiency of activated carbon adsorption method is 99.2%~99.3%. For the treatment of large air volume and low concentration of organic waste gas, it is agreed that this method is the most mature and reliable technology at home and abroad, but the T art process is too long, the operation cost is high, and it is often more difficult to need a stable steam source. In view of these problems, combined with the characteristics of this graduation design and only body requirements, the use of activated carbon fixed bed adsorption system for industrial organic waste gas purification, the selection of honeycomb activated carbon as adsorbent.The process system is compact and integrated with adsorption and desorption.

Why activated carbon granular shell activated carbon has such a good effect02021-06-28 18:55:05
High-quality granular activated carbon must have good adsorption performance and strength. Like powdery activated carbon, the adsorption performance of granular activated carbon depends largely on the characteristics of pore structure. The adsorption performance index can be analyzed and characterized by different methods, such as the decolorization performance of activated carbon expressed by methylene blue. Other performance indexes include iodine adsorption value, caramel decolorization rate, etc.dxdcarbon carbon  The pore structure characteristics and specific surface area of activated carbon are usually obtained by measuring nitrogen adsorption isotherm at low temperature with adsorption In addition, the adsorption capacity of activated carbon also has a great relationship with its internal pore structure, pore size distribution and surface chemical properties. activated carbon suppliers in uae  Chemical method in addition to certain micropores, macropores, there are more mesopores (transition pores), so it is more suitable for the application of liquid phase, adsorption of larger molecules of substances, such as sugar solution has a good decolorization effect; When purifying water quality, it can also remove the colored material well and achieve the specified chroma requirements. The kinetic activity value of adsorbent is the main basis for the design of adsorption system. The adsorption rateThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, the adsorption process can be divided intoThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, which can be divided into the following steps (1) External diffusion, the adsorbate from the main air flow through the air film around the particles to the outer surface of the adsorbent; (2) Internal diffusion, the adsorbate from the outer surface through micropores to the surface of the adsorbent micropores (3) adsorption, the adsorbent reached the microporous surface of the adsorbent is adsorbed (4) The desorbed adsorbate diffuses to the main body of the gas phase through internal and external diffusionPhysical adsorption process is generally controlled by internal and external diffusion, chemical adsorption is controlled by both surface dynamics and internal and external diffusion.Because of the complexity of the adsorption process and many influencing factors, it is difficult to derive the rate theoretically, so it is generally determined by experience or model experiment.

The isobarisothermal adsorption properties of activated carbon at different temperatures, at different pressures and at different flow rates were determined by using the gas produced in the system as samples.The adsorption effluent curve of benzene by activated carbon was plotted.activated carbon gold mining  The effects of different temperature on the regeneration performance of activated carbon under static environment, the effects of steam at different temperature on the regeneration performance of activated carbon under dynamic environment and the effects of nitrogen at different temperature on the regeneration performance of activated carbon under dynamic environment were studied.activated carbon company  The experimental results showed that high pressure and low temperature were beneficial to the adsorption, and the flow rate had little effect on the equilibrium adsorption capacity in the range of experimental flow rate. The adsorption capacity of benzene by activated carbon in the experiment was 150~170mg/g under operating conditions. At the same time, the filtration and adsorption properties of coke were tested. The experiment shows that the adsorption performance of the test coke on benzene is very weak, can not be used as the nitrogen adsorbent, but the coke filter and adsorption performance of ash and naphthalene is very good, the content of naphthalene and ash after the gas through the coke column completely meet the design requirements. The results show that the combined use of coke and activated carbon in the gas system can completely achieve the purpose of removing benzene, naphthalene and ash. According to the above research results, a coke filter was designed. The application of the equipment solved the problems that the feedstock gas compressor in the urea blackening unit could not run for a long period due to the vibration caused by the scaling of the rotor, the blockage of the flow channel and the problems that the naphthalene formation in the heat exchanger affected the heat transfer effect.
