Abstract
The utility model provides a novel integration device that is used for highly effective desulfurizing and dust-removing the smoke of a coal-fired boiler and a furnace, and adopts the carbon steel and wear-resisting corrosion-resisting coating as well as stainless steel compound structure. The bottom of a case body is an ash discharging settling tank, the inner part is arranged with an ash discharging pipe which can discharge the mortar timely. One side of the case body is arranged with a flooding water tank that can be used for observing the liquid level and leading the flooding to a circulating settling pool at the bottom. The novel integration device can be completed with the highly effective desulfurization and dust removal functions, and can realize the automatic control of the liquid level and ash-discharging and PH value. Compared with the like equipment, the utility model has the advantages of more compact structure, lower height, and smaller accommodation area; the utility model integrates the dust removal and the desulfurization into a whole, and has better running reliability.
Description
The utility model provides a kind of integrated apparatus that can be used for coal-burning boiler, stove flue gas desulfurization and dedusting.Adopt carbon steel, inorganic coating and the compound structure of stainless steel.
At present, China's coal-burning boiler, stove flue gas integrated desulfurization dust-removing equipment are the steel welding structure substantially.The steel welding structure lowly becomes the two large problems that has a strong impact on the desulfurization and dedusting operational reliability because weak acid corrosion in the running and erosive wear usually cause the equipment corrosion perforation with demist dewatering means technical merit.
Problems such as I am in the disclosed a kind of integrated spray dust removing desulfurizer of ZL98215227.2 document, promote though the whole nation is existing, but still exist system complicated, and the higher and demist dehydration technique measure of setting height(from bottom) is incomplete.
The purpose of this utility model is the deficiency that exists in the said goods technology, and a kind of efficient desulfurizing and dust collecting integrated apparatus of overflow endless form is provided, and adopts carbon steel, abrasion-proof corrosion-proof erosion resisting coating and the compound structure of stainless steel, integrates desulfurization and dedusting.Under the prerequisite that guarantees operational reliability, the simplification system reduces setting height(from bottom) greatly, optimizes the measure of demist dehydration technique, effectively improves desulfurization dust-removing efficiency, satisfies more strict emission control standards requirement.
The technical solution of the utility model is that device is formed by a square casing 1 with at the circular chimney fan 4 that is provided with thereafter.The flue gas of discharging from combustion apparatus enters casing by blast pipe 2, at first the absorption liquid with double-level atomizing nozzle 3 ejections mixes, flue gas humidification weightening finish back is impacted to lower box absorption liquid liquid level, again through flap, water fender guiding flue gas impact liquid level and make the flue dust that is captured, the absorption liquid that desulfurization resultant imports the bottom once more in dilatation, turnover motion.The casing rear portion is provided with the demist dehydration tube 8 that the eddy flow plate is housed, and further impels the coalescence of fine dust and sulfur dioxide reaction product in the flue gas, to the falling of bottom absorption liquid, earial drainage.Flue gas is forced to centrifugal rotation by demist dehydration eddy flow plate 7, liquid mist in the flue gas is fully separated, and condense in circular chimney fan 4 inwalls, gravitate also protrudes dash for annular and stops downward earial drainage along plate structure 5, enter the bottom absorption liquid by tapping pipe 9, purify flue gas and discharge from top, also can efficiently handle through external dewatering device again through drip ring 6.The flue dust that is captured, desulfurization resultant enter circulation precipitation pond 15 by the ash discharge suction pipe 14 that is provided with in the groove through waterpower deashing pump 16 in bottom half subsider 13 depositions.Clarified solution causes atomizer 3 by circulating pump 17 and repeats to enter desulphurization circulating.Casing middle part installing has spill box 11, the relief sewer 12 of window 10, guarantee open, shut down two state liquid levels accurately, stable.Moisturizing, adjustment absorption liquid pH value are all carried out closed cycle at circulating water pool.
The utility model can be adjusted feed flow flow or pH value and can adapt to the more occasion of high desulfurization efficiency requirement at bottom circulating water pool configuration pH value monitoring and automatic adder-subtractor.
As shown in the figure, 1 is casing, and 2 is blast pipe, 3 is atomizer, and 4 is circular chimney fan, and 5 is that dash is along plate, 6 is drip ring, and 7 is the eddy flow plate, and 8 are the demist dehydration tube, 9 is tapping pipe, and 10 is window, and 11 is spill box, 12 is relief sewer, and 13 is the bottom subsider, and 14 are the ash discharge suction pipe, 15 is circulating water pool, and 16 is waterpower deashing pump, and 17 is desulfuration recycle pump.
This device is than general desulfurizing dust-collector more compact structure, takes up an area of forr a short time, and setting height(from bottom) is lower, integrates dedusting and desulfurizing function, has better operational reliability, and is outstanding with the complete performance of boiler, has very big promotional value.
