MS sulfur bubble dedicated filter/sulfur bubble filter/sulfur recovery

MS sulfur bubble filter Integrating the nano inorganic membrane technology, ultrasonic technology and automatic control. Absorption, regeneration, sulfur recovery are indispensable processes in wet oxidation desulfurization. But there are many questions about sulfur recovery in actual production. Especially in recent years, due to the expand of production scale and the lack of coal, this made the rapid application of high-sulfur coal, and the higher precision demand to H2S, sulfur recovery is more and more important in desulfurization. In the existing sulfur recovery traditional technologies, generally use continuous melting sulfur and batch-type melting sulfur, the batch-type was replaced by continuous type, this is a revolution in desulfurization. This is not only saved amount of manpower, material resources and financial resources, but also greatly reduced environment pollution, can be said that it is popular in the industry up to now.However, as time goes on, the expand of production scale made the treatment quantity in unit time of H2S significant increased, so that the residues after melting sulfur increased much, this can increase the treatment difficult in the process of cooling, dropintemperature and subsidence, also can increase the chance for HS- oxidized to S2O3-. The production of vice salt can greatly reduce the quality of desulfurization solution, not only influence the desulfurization rate, but can block the equipments, pipelines and fillings. The additional sulfur recovery technology is hard to adapt to the modern production, face to such problems, what measures should be taken to change this negative situation?We know that, the sulfur bubble from the regeneration trough(regeneration tower) about 80% is desulfurization solution, only about 20% is elemental sulfur. And due to the different catalyst and regeneration conditions, the content of sulfur is less than 10%, all these sulfur bubble enter into the sulfur melting kettle, not only increase the steam consumption, but can increase the difficulty of dealing with residues. But if we use filter pressing, press the bubble, then melt it, then many problems would be solved. But the traditional technology has many problems, so this process has no better development and utilization. In view of these situations, the DS sulfur bubble dedicated filter our company developed, fill some deficiency of filters at fundamentally, set the merits of all kinds of filters current and past, after experiment, has satisfactory effect, the novelty and practicality has the leading domestic level. 1,Equipment introduction:MS sulfur bubble dedicated vacuum filter is a late-modal, high efficiency, energy conservation and environmental solid-liquid separating equipment, integrating the nano inorganic membrane technology, ultrasonic technology and automatic control. It's on the basis of desulfurization solution component and their special physico-chemical property, in the condition of no influence on solution component, use different ultra micro hole to filter out the sulfur from the sulfur bubble.The filter cake can sale or melt in the sulfur melting kettle. Because of using nano technology, the sulfur content in the desulfurization solution is very low(the removal rate of sulfur can above 99.9%), and the solution after filtered is limpid (solid content <50PPm). And because this is physical filter, the physico-chemical property has no change. This can recovery sulfur directly, so can greatly save energy, pollution to environment and harmful to system.2,Operating principle:MS desulfurization vacuum filters use nano ceramic technology: In the role of vacuum force, the filter medium can only permit the desulfurization solution get through the ultramicro ceramic fenestra, but the mechanical mixture, elemental sulfur and bubble can't. This can ensure there are no vacuum loss, greatly reduce the energy consumption of vacuum filters and the solid content of filtrate.3,Working process:MS vacuum filter consists of filter board, rotor, slurry bucket, vacuum system, cleaning system, and control system. When working, in the role of vacuum force and capillarity, the surface of the filter board which submerged in the hopper, can absorb and form a layer of material. The filtrate flow through the filter board into the drainage tank, the filter cake in arid region goes on dehydrating under the action of vacuum force. After drying, use scraper discharge the filter cake, then went into backwashing area, use circulating water to clean the filter board, then to complete a working cycle. When the filter has been worked for about 7 hours, use ultrasonic wave and alkaline water to wash it, so as to keep the efficient operation of filter. Bag the filter cake or melt them in the desulfurization melting kettle.4,Features:1),Has clean and non-pollution working environment.2),Hight vacuum degree, the filter cake has lower moisture than traditional filter. The dryness of filter cake can reach up to above 70%.3),Compact structure, small floor space, easy to install and maintain.4),Low energy consumption, can save about more than 90% compared with other filter equipments.5),The filtrate is limpid, solid content <50ppm. Is re-usable, can improve economic performance and reduce system regeneration load.6),The filter board used the latest international nano inorganic membrane micropore technology, has long service life and good filter effect.7),High automaticity, can reduce the labor intensity and the number of the operating personnels.
