Description
Technical field
The utility model relates to the smoke eliminator of middle-size and small-size coal combustion equipments such as a kind of boiler, kiln, particularly relates to a kind of integrated apparatus of novel combination boiler flue gas desulfurization and dedusting.
Background technology
China's energy resource structure is based on coal, and coal accounts for about 70% of primary energy aggregate consumption, because China's petroleum resources shortage, this structure will be difficult to change in a short time.Coal directly burning discharges volume of smoke, SO
2, NO
XDeng gas, cause air environmental pollution, to the ecosystem generation ten minutes adverse influence of global climate and China.At present, China's dedusting technology is ripe relatively, and flue gas desulfurization technique also mainly relies on introduction, and in various boiler flue gas desulfurization technology, wet desulphurization is most effective, and lime/gypsum method FGD technology is the most ripe in all kinds of desulfurizers, most widely used, but its cost height, floor space is big, complicated operation, the operating cost height is difficult to apply in middle-size and small-size Industrial Boiler.At the national conditions of China, it is very urgent to accelerate research and development desulphurizing and dust-removing integral technology and equipment.
Efficient mechanical cyclone dust collectors are used more in the medium and small Industrial Boiler dry-type dedusting equipment of China at present, has simple to operate, reliable advantage as multi-tube dust cleaner, but to the micronic dust of diameter in the flue gas less than 5 μ m, dust removing effects is not good, and can not remove the SO in the flue gas
2And in the wet-scrubbing equipment, it is simple in structure, easy to operate that water dust scrubber has, operation and maintenance cost is low, the efficiency of dust collection advantages of higher, but it needs bigger water consumption, especially when the flue-gas temperature height, when containing big dust particle in the flue gas, tube wall of dust settler influences the formation of even moisture film easily by erosion corrosion, thereby reduces its efficiency of dust collection.
The utility model content
The technical problems to be solved in the utility model is that a kind of novel compound high-efficiency desulfurizing dust-collector that medium and small Industrial Boiler flue gas is handled that is suitable for is provided on the basis of above-mentioned dry dust removal and wet dust removal device.
In order to solve the problems of the technologies described above, the utility model is made up of smoke inlet, multi-tube dusting assembly, collection chamber, dust removal with desulfurization by water film assembly, lye tank (vat) and exhanst gas outlet; Described smoke inlet is connected with the multi-tube dusting assembly; Described multi-tube dusting assembly by smoke distributing chamber, efficient cyclone, ash bucket, lock, ash hole is formed and be connected with the dust removal with desulfurization by water film assembly by collection chamber; Described dust removal with desulfurization by water film assembly by tower body, feed pipe, overflow launder, hollow current stabilization annotate, demister is formed and link to each other with exhanst gas outlet, and the opening that passes through on the hollow current stabilization post is communicated with lye tank (vat); Described collection chamber is made up of two low-resistance runners and diversion chamber, and the circular arc line of the inside and outside contour line of two low-resistance runners and tower body inwall is tangent, and the spiral stream guidance blade is housed in diversion chamber; Be provided with overflow baffle in the described lye tank (vat), lye tank (vat) is divided into decanting zone and clear liquid area.
The utility model is the result that process is optimized multi-tube dust cleaner and water dust scrubber composite design, compact conformation, simple to operate, stable and reliable operation, floor space, initial cost and operating cost have been reduced, have advantages such as corrosion-resistant, wear-resistant, long service life simultaneously, efficiency of dust collection can reach 95～98%, and desulfuration efficiency can reach 80～85%.

The specific embodiment
By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be seen, the utility model is made up of smoke inlet 1, multi-tube dusting assembly 2, collection chamber 3, dust removal with desulfurization by water film assembly 4, lye tank (vat) 5 and exhanst gas outlet 6; Smoke inlet 1 is connected with multi-tube dusting assembly 2 by the ring casing passage; Multi-tube dusting assembly 2 is connected with dust removal with desulfurization by water film assembly 4 by collection chamber 3; Dust removal with desulfurization by water film assembly 4 links to each other with exhanst gas outlet 6; Have hollow current stabilization post 7 on the dust removal with desulfurization by water film assembly 4, and be communicated with lye tank (vat) 5 by hollow current stabilization post 7; Collection chamber 3 is made up of low-resistance runner 8, diversion chamber 9, low-resistance runner 10, and low-resistance runner 8 intersects with low-resistance runner 10, and staggers 90 °, and the inside and outside contour line of low-resistance runner 8 and low-resistance runner 10 is and the tangent circular arc line of tower body 16 inwalls; Diversion chamber 9 is equipped with spiral stream guidance blade 22, and is communicated with tower body 16 inner chambers by low-resistance runner 10.
Dust removal with desulfurization by water film assembly 4 of the present utility model is made up of tower body 16, feed pipe 17, overflow launder 18, hollow current stabilization notes 7, demister 19; Tower body 16 is concentric with hollow current stabilization post 7, and demister 19 is installed on current stabilization post 7 tops, and demister 19 separates tower body 16 inner chambers and exhanst gas outlet 6; The liquid of tower body 16 inner chambers flows into lye tank (vat) 5 by the opening 21 of hollow current stabilization post 7, the inner chamber of lye tank (vat) 5 is divided into decanting zone and clear liquid area by overflow baffle 20, to feed pipe 17 feed flows, feed pipe 17 communicates with tower body 16 inner chambers by overflow launder 18 lye tank (vat) 5 by circulating pump 23.
