Graphite absorber itself is a graphite equipment, and very much loved by the profession, of course, this is also mainly due to this equipment goods have good corrosion resistance, acid and alkali resistance. In addition to these, it has many other advantages.
Graphite absorber itself is a graphite equipment, and very much loved by the profession, of course, this is also mainly due to this equipment goods have good corrosion resistance, acid and alkali resistance. In addition to these, so that it has a lot of other advantages.
In the equipment investment graphite absorber with the previous equipment products compared to a substantial reduction. In terms of investment, each absorption line is reduced by a graphite absorber, it can be seen that it has great advantages. And its operating costs are reduced, the absorption tower packing section for adiabatic absorption, segmented absorption technology in the secondary absorption tower without circulating water cooling program, reducing the consumption of cooling water. Of course, also because of its many advantages, it is very popular in the industry, because this equipment products have good corrosion resistance, acid and alkali resistance, because this equipment is a heat exchange equipment, so it can take away the heat generated by the dissolution of chlorohydrin in a timely manner, to complete the absorption of most of the chlorohydrin gas, the formation of a high concentration of hydrochloric acid solution, so the graphite absorber and hydrochloric acid has a very close relationship. Of course, compared with the previous equipment products are greatly reduced, in terms of investment in each absorption line reduces a graphite absorption tower equipment.
Graphite absorber although there are many advantages, but there are also many things to pay attention to. For example, after a long time, there will be a lot of impurities left inside. In order to achieve a smooth processing effect, the cleaning effect should be strengthened, and the use of immersion liquid that can dissolve the crystallization (or precipitates), so as not to damage the graphite components. The liquid (or hot water) rinses the longitudinal holes from top to bottom. At the same time, it is strictly prohibited to suddenly raise or lower the temperature so as not to damage the multi-functional graphite absorber equipment. Installation of pressure reducing device. Or the operation buttons should be used correctly in the production process. Once the graphite absorber is faulty, it must be shut down for inspection. If the graphite absorber is blocked by crystallization, it can be heated and melted to clean. Handle the material which is easy to scale, the material should be drained when stopping and make sure there is material before cleaning. Graphite absorber adopts two-stage series connection, cycle absorption, efficiency can reach more than 98%, can be used for the synthesis of chlorine hydrogen and recycling chlorine hydrogen gas absorption, can also be used for H2, S, SO2, NH3 and other gases absorption, in this way it is also very good to get the concentration of the product is higher than the adiabatic absorption of 5%, the absorber can be adjusted to a larger range of generating capacity, easy to control, for example, said that the two sets in its For example, in its two 10m2 membrane absorbers used in series, a day can be obtained 31% hydrochloric acid 10 to 20 tons, in the case of the same gas flow rate, parallel flow when the fluid resistance is much smaller than the countercurrent.
About "Precautions for using graphite absorber?" Some basic information about "Precautions for using graphite absorber?" is said here.
