Abstract
The utility model relates to a tangential air intake dust removing desulfurization three-phase fluidized bed, comprising a desulfurization tower < (6) > and a venturi tube < (1) >. In a desulfurization tower body, from top to bottom, a cyclone plate demister < 5 >, a lime stone liquid spraying device < 4 >, a stuffing ball, stuffing grid < 3 > and a water spraying desuperheater < 2 > are in turn arranged. The bottom of the desulfurization tower body is provided with a dust water discharge port < (7) >. The venturi tube is communicated with the desulfurization tower in the direction which is tangent with the desulfurization tower body between the dust water discharge port and the water spraying desuperheater. Dust removing and desulfurization are collected in one space, the utility model is characterized in small energy consumption, small land occupation, investment saving, easy modification, etc.
Description
The utility model belongs to environmental protection technical field, particularly a kind of three phase fluidized bed that boiler smoke is carried out dedusting and desulfurization.
Three phase fluidized bed to boiler smoke dedusting and desulfurization has three classes substantially at present: a class is that venturi wet type water film type duster (is seen " boiler handbook P522～535, Xi'an Communications University), to be flue gas go into water dust scrubber through venturi water spraying atomization flue dust humidification is laggard to its operation principle, part flue dust pours the ash bucket of water dust scrubber with water, another part flue dust then tangentially enters the centrifugal force of generation with gas, the moisture film that forms on flue dust and the cylinder inboard wall is contacted, by water adhesion, reach the dedusting purpose.But owing to only wash flue gas, thereby not exclusively possesses desulfurizing function with clear water; Another kind of is radial air inlet three phase fluidized bed absorption tower (seeing " cleaner design " P345～350), although this class absorption tower has higher desulfuration efficiency, but because dedusting function is not strong, therefore then need preposition electric cleaner or cleaner for the higher flue gas of dust-laden, stop up to prevent the absorption tower.The 3rd class is a radial air inlet three phase fluidized bed combined type desulfurizing tower, this class desulfurizing tower and the utility model are the most approaching, its eddy flow plate demister from top to bottom to arrange successively in the tower, the limestone slurry spray equipment, the desulfurization section of being formed by filling ball and filler grid, direct-contact desuperheater, below direct-contact desuperheater, form to the Venturi tube of joining with canal path with tower body, and be provided with buck outlet (" exhuast gas desulfurization " P123～133) at tower bottom, although this class device has dedusting and two kinds of functions of desulfurization concurrently, but because after the flue gas of sending here from Venturi tube enters the absorption tower with radial direction, gas directly makes progress, its dust removing effects is not good, easily causes the filling ball wearing and tearing.
The purpose of this utility model is exactly a kind of tangential admission dust-removal and desulfurizing three phase fluidized bed that has dedusting and two kinds of functions of desulfurization concurrently of developing at above-mentioned situation.
The utility model is made up of desulfurizing tower 6 and Venturi tube 1.In desulfurizing tower, be furnished with eddy flow plate demister 5, lime stone slurry spray equipment 4, filling ball and filler grid 3, direct-contact desuperheater 2 from top to bottom successively, and have buck outlet 7 in its bottom.Venturi tube between buck outlet and direct-contact desuperheater to be connected with desulfurization tower body tangential direction and desulfurizing tower.
In actual use, the utility model and stock mixing system and the supporting use of grey water clarification system, lime stone spray equipment 4 is connected with stock mixing system, buck outlet 7 is connected with grey water clarification system, its course of work is as follows: flue gas to be desulfurization tangentially enters desulfurizing tower 6 after Venturi tube 1, flue gas rises after spray cooling device 2 further reduces the cigarette temperature, after the dust-removal and desulfurizing section that arrival is made up of filling ball and filler grid 3, by the lime stone slurry washing desulphurization dedusting under drenching from spray equipment 4.Flue gas behind the dust-removal and desulfurizing enters flue after eddy flow plate demister 5 demists at top, absorption tower, buck then enters grey water clarification system from buck outlet 7.
The tangential admission dust-removal and desulfurizing three phase fluidized bed of making according to the utility model, not only possess two kinds of functions of dedusting and desulfurization, and owing to adopted the tangential admission connected mode, its flue dust tangentially enters the centrifugal force of generation with gas, the moisture film that forms on flue dust and the cylinder inboard wall is contacted, washed into ash bucket by water, dust removing effects is (more than 98%) significantly, desulfuration efficiency height (more than 80%).And have that process is simple, energy consumption is low, occupation of land is little, reduced investment, operating cost be low, transform easily, spare and accessory parts be easy to processing or can be supporting at home etc. characteristics.
Accompanying drawing is a structure diagram of the present utility model.1-Venturi tube among the figure, 2-spray cooling device, 3-filling ball and filler grid, 4-lime stone slurry spray equipment, 5-eddy flow plate demister, 6-desulfurizing tower, 7-buck outlet.
