Desulphurizing Deduster
Desulfurization Dust Collector is a professional desulfurization equipment for turbocharged turbulent dust removal and desulfurization technology.
introduce
The principle of the work is that the sulfur containing gas is subjected to a turbocharged turbulence device, with the state of high speed rotation and diffusion and the intensified turbulent mass transfer formed by the absorption slurry. The process of mass transfer is to make gas liquid form emulsion layer, not only chemical absorption and fast, but also close to neutral, so it can keep the whole process high and stable mass transfer rate. Therefore, it is a very excellent low resistance and high efficiency desulfurization equipment.
The company has turbocharged turbulent mass transfer desulfurization equipment technology, belonging to the third generation of high-tech products. Its technical core is: Based on the theory of permeable surface updating, based on the strong mass transfer mechanism of mixed turbulence, it belongs to the purpose of separating the dispersed dust particles, smoke and harmful gases from gas, air or waste gas by using liquid as a separation agent and purifying the dust from gas, air or exhaust gas, and has the high technology of dust removal and desulfurization at the same time. Characteristics are: dust removal and desulphurization integration, low energy consumption, small area, simple operation, high efficiency, low operating cost, no clogging, stable operation, low pressure resistance loss, suitable for various sulfur fixing agents (CaO, MgO, NaOH, CaCO3, Na2CO3, NH3, H2O, industrial waste alkaline solution) and other advantages. At home and abroad, the technology of wet dedusting and desulfurization is at the leading level. And in the application of coal-fired industrial boilers, the achievement of zero emissions is achieved.
The desulfurization equipment is used in the industry of desulfurization and dust removal in coal fired boiler. The dust removal and desulfurization equipment can be used widely. It can be wet and wet desulphurization, and it can also be integrated with dust removal and dust removal. It is not only suitable for dust removal and desulfurization of coal-fired circulating vulcanized bed boilers, but also can be applied to the wet desulphurization, dust removal and flue gas purification of coal fired chain boilers and two oxygen removal. The sulphur efficiency is high and the tail gas is cleaned thoroughly. It is used in the furnace industry to remove the hydrogen fluoride and the acid waste gas purification equipment of the kiln tail gas, and the desulphurization of the tail gas of pellets and sintering machines. The purification efficiency of desulfurizer is very high. The SO2 of the original flue gas is removed from 11000mg/m3 to below 120mg/m3. It is widely used in the pellet smoke field of steel mill. It is a low resistance and high efficiency wet dust removal and desulfurization equipment and a new desulfurization equipment environmental protection product. Dust remover is used to remove harmful dust in the gas phase. On this basis, the desulfurization effect is increased, that is, the desulphurization dust collector.
Desulphurizing dust collector is generally wet desulphurizing dust collector, wet desulphurization and dust removal has water membrane desulfurization and dust removal, impact water bath desulfurization and dust removal.
The advantages of wet dust removal are easy to maintain, and can be prepared by different dedusting agents, at the same time, the effect of dust removal and desulphurization (denitrification) is achieved; the disadvantage is that the dedusting liquid needs to be treated, which may lead to two pollution.
After years of improvement, various types of water film desulfurization and dust remover have been developed, such as hilly type, swirling plate type, swirl column type, floating ball type, sieve plate type, and so on. Equipment technology is becoming mature day by day, each has advantages and disadvantages, and enterprises can choose different types according to their own needs.
Working principle
Desulphurization is a technology to control sulfur dioxide emissions. The dust collector can not only remove sulfur dioxide from flue gas, but also produce high value-added sulphuric acid ammonia fertilizer products. The boiler dedusting equipment uses a certain concentration of ammonia water (28% as an example) as desulfurizer, and produces the sulphuric acid ammonia slurry which is transported to the chemical fertilizer plant treatment system. The ammonia demand in the desulfurization process is automatically adjusted by the preset PH control valve and measured by the flowmeter. The sulphuric acid ammonia crystals crystallized in saturated sulphuric acid ammonia slurry in the desulphurization dust collector to produce suspended particles with a weight ratio of about 35%. These serous quilts are pumped to the processing field, dehydrated through primary and two stages, and then sent to the chemical fertilizer plant for further dehydration, drying, condensation and storage. The boiler dust remover also generates a considerable by-product to achieve a definite economic benefit.
