Description
(1) technical field
The utility model belongs to atmospheric environment protection technical field, particularly one mixing two-phase desulfuring and denitrifying dedust apparatus.
(2) background technology
At present, the large medium-size boiler equipment desulfurization project capital construction of coal-burning power plant of China is complete, and in normal operation.Particularly two-phase flue gas treating process because for the treatment of effeciency high and most widely used, mainly hollow-spraying-tower and bubble tower etc.
But along with China's improving constantly environmental requirement, original reaction tower all cannot reach the requirement of new discharge standard, in order to meet emission request, a lot of producer adopts the mode of double-column in series to transform existing equipment, although the SO after transformation in flue gas
2can reach standard, but the discharge of flue dust still can not meet emission request, need to increase the equipment such as wet electrical dust precipitator after desulfurization, to meet the standard of emission request.By above-mentioned improved enterprise, general problem is: construction investment is high, operation is complicated, operating cost is high, equipment guarantee rate is low, and the burden of enterprise increases greatly.
(3) summary of the invention
The utility model in order to make up the deficiencies in the prior art, provide a kind of desulfurization dust-removing efficiency high, there is denitration function, parallel-adder settle-out time is long, operating cost is cheap, less scaling, absorbent utilization ratio is high, can reach the mixing two-phase desulfuring and denitrifying dedust apparatus of more than 90% to the removal efficiency of PM2.5.
The utility model is achieved by the following technical solution:
A kind of mixing two-phase desulfuring and denitrifying dedust apparatus, comprise tower body, tower body top is provided with spray storehouse, and spray storehouse side opening is provided with smoke inlet, it is characterized in that: bottom, described spray storehouse is provided with surge bunker, and surge bunker bottom is provided with bubbling storehouse.
Described spray storehouse is connected with surge bunker by decline passway, is provided with down-comer, offers aperture bottom down-comer in surge bunker.
Be provided with liquid storage tank in described bubbling storehouse, liquid storage tank is connected with spray storehouse by collector tube, and side, bubbling storehouse is provided with exhanst gas outlet, and exhanst gas outlet is connected with flue, is provided with demister in flue.
Some spraying layers are provided with in described spray storehouse.
Described liquid storage tank is connected with spraying layer by circulation slurry pump.
The beneficial effects of the utility model are: the shortcoming overcoming the not up to standard and easy fouling of bubble tower of spray column flue gas band slurry dedusting, has the feature that spray column is stable, desulfuration efficiency is high and bubble tower efficiency of dust collection is high concurrently simultaneously.By two-step desulfurization dedusting, while improving desulfuration efficiency, also assures that the efficient removal of flue dust, ensure that whole desulphurization system is steady in a long-term and run efficiently.By the simple adjustment to inner desulfurization zone, the raising of environmental protection standard recent and at a specified future date can be tackled; And once build, gradation simply adjusts and is conducive to owner and reduces investment, is a kind of energy-efficient new desulfurization process.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is process chart of the present utility model;
In figure, 1 tower body, 2 spray storehouses, 3 smoke inlets, 4 surge bunkers, 5 bubbling storehouses, 6 decline passwaies, 7 down-comers, 8 apertures, 9 liquid storage tanks, 10 collector tubes, 11 exhanst gas outlets, 12 flues, 13 demisters, 14 spraying layers.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises tower body 1, and tower body 1 top is provided with spray storehouse 2, and spray storehouse 2 side opening is provided with smoke inlet 3, and spray bottom, storehouse 2 is provided with surge bunker 4, and surge bunker 4 bottom is provided with bubbling storehouse 5.Spray storehouse 2 is connected with surge bunker 4 by decline passway 6, is provided with down-comer 7, offers aperture 8 bottom down-comer 7 in surge bunker 4.Be provided with liquid storage tank 9 in bubbling storehouse 5, liquid storage tank 9 is connected with spray storehouse 2 by collector tube 10, and side, bubbling storehouse 5 is provided with exhanst gas outlet 11, and exhanst gas outlet 11 is connected with flue 12, is provided with demister 13 in flue 12.Spray is provided with some spraying layers 14 in storehouse 2.Liquid storage tank 9 is connected with spraying layer 14 by circulation slurry pump.
Adopt mixing two-phase desulfuring and denitrifying dedust apparatus of the present utility model, flue gas after deduster process, first spray storehouse 2 is entered from the smoke inlet 3 of spray side, storehouse 2, spray storehouse 2 arranges spraying layer 14, the slurries utilizing circulation slurry pump to extract in liquid storage tank 9 spray flue gas, flue gas rise process in spray slurries generation counter current contact, complete while cooling first time SO
2, NOx and flue dust removing; Then flue gas enters surge bunker 4 through decline passway 6, and the flue gas in surge bunker 4, after first compression-expansion, is overflowed from the aperture 8 bottom down-comer 7, entered bubbling storehouse 5; The flue gas entering bubbling storehouse 5 carries out bubbling with the slurries of liquid storage tank 9 in bubbling storehouse 5 and contacts, and completes second time desulphurization denitration and dedusting.Flue gas after secondary response is discharged by the exhanst gas outlet 11 of side, bubbling storehouse 5, by after demister 13 demist through smoke stack emission.After the slurries in spray storehouse 2 and flue gas complete first set reaction, be delivered in the liquid storage tank 9 in bubbling storehouse 5 by the collector tube 10 in surge bunker 4.Spray storehouse 2 are decentralized photo (flue gas) counter current contact with decentralized photo (slurries), decentralized photo (flue gas) contact-impacts with continuous phase (slurries) in bubbling storehouse 5, by both combination thus improve collision frequency, reach the object absorbing oxysulfide, nitrogen oxide and dedusting.The nitrite of twice desulphurization denitration generation and sulphite, through air blast oxidation, form nitrate and sulfate sediment, the salt containing flue dust is Separation of Solid and Liquid after dehydration, and solids is piled up and processed, and clear liquid returns in tower body 1 and re-uses.
