The utility model discloses save area, reduce the civil engineering expense, improve flue gas smoothness nature simultaneously, sparingly connect flue steel quantity.
Description
Technical field
The utility model relates to a kind of purifier, and especially a kind of smoke-removing purifier for boiler, belongs to power plants generating electricity apparatus field.
Background technology
Along with becoming increasingly conspicuous of China's problem of environmental pollution, especially haze weather brings day by day serious impact to the life of people and health, in order to reduce the discharge of pollutant, improve discharge standard, smoke-removing purifier for boiler is more and more extensive in the use of coal-fired power plant.
Existing smoke-removing purifier for boiler mainly comprise connect successively electrostatic precipitator, air-introduced machine, absorption tower and wet scrubber, electrostatic precipitator and the smoke discharging pipe of boiler are directly connected for removing the dust in flue gas, flue gas is introduced in desulfuration absorbing tower by electrostatic precipitator outlet connection air-introduced machine, desulfuration absorbing tower top exit place is connected with flue collector, flue collector is arranged and connects flue and connect wet scrubber, the port of export of wet scrubber to be connected with another flue collector by connection flue and to be entered in air by the flue gas after purifying.Often purification demand can not be met in order to increase specific collection area wet scrubber, therefore often on same height, arrange multiple wet scrubber be arranged in parallel, the import of each wet scrubber and outlet all arrange elbow and are connected flue and realize being connected with flue collector.
The arrangement of existing deduster makes smoke eliminator floor space large, smoke canal elbow is more simultaneously, connect flue consumption large, make flue resistance excessive, connect flue rolled steel dosage and increase, the increase of the resistance of elbow flue simultaneously also directly affects model selection of ID fan, and powerful air-introduced machine result also in the increase of power consumption.
Utility model content
The utility model technical issues that need to address are to provide a kind of smoke-removing purifier for boiler of coal-burning power plant, save floor space, reduce civil engineering costs, improve flue gas fluency simultaneously, save and connect flue rolled steel dosage.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of smoke-removing purifier for boiler of coal-burning power plant, comprise the electrostatic precipitator, air-introduced machine, desulfuration absorbing tower and the wet scrubber that are connected successively with boiler, the outlet of described desulfuration absorbing tower top is connected with U-shaped flue collector by horizontal flue collector, between two vertical flue collectors of described U-shaped flue collector, along horizontally set on flue height direction, several connect flue, and the horizontal flue collector of described U-shaped flue collector bottom and connection flue all arrange the wet scrubber adopting horizontal layout.
The further improvement of technical solutions of the utility model is: the below of described wet scrubber arranges discharge casing, and the discharge outlet of described wet scrubber is connected with discharge casing by pipeline.
The further improvement of technical solutions of the utility model is: described wet scrubber quantity is for being 1 ~ 2.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
Smoke discharging and purifying device of the present utility model is purified smoke evacuation by electrostatic precipitator, desulfuration absorbing tower and wet scrubber classification, improves the clean-up effect of smoke evacuation.Wet scrubber is changed into by the horizontal traverse of multiple stage and vertically arranging on differing heights simultaneously, reduce wet scrubber floor space, reduce initial cost, and wet scrubber is vertically arranged so that elbow and is connected the minimizing of flue consumption, elbow minimizing makes flue gas flow direction more smooth and easy, reduces flue resistance; Connect flue and reduce saving rolled steel dosage, reduce costs.
Discharge casing is arranged on the below of wet scrubber, and the discharge outlet of wet scrubber is connected with discharge casing by pipeline, the water produced directly is drained in discharge casing and ensure that pipeline consumption is minimum in wet scrubber, practical and save.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further details:
As illustrated in fig. 1 and 2, the utility model is a kind of smoke-removing purifier for boiler of coal-burning power plant, comprise the electrostatic precipitator 2, air-introduced machine 3, desulfuration absorbing tower 4 and the wet scrubber 5 that are connected successively with boiler 1, classification purifies smoke evacuation, improves the clean-up effect of smoke evacuation.
Exit, desulfuration absorbing tower 4 top connects a U-shaped flue collector 8 by horizontal flue collector 6, U-shaped flue collector 8 comprises two vertical flue collectors and a horizontal flue collector, and horizontal flue collector is arranged on the lower end of U-shaped flue collector 8 and is coupled together by two vertical flue collectors.Along 1 the connection flue 7 of horizontally set on flue height direction between two vertical flue collectors of U-shaped flue collector 8, the horizontal flue collector connecting flue 7 and U-shaped flue collector 8 bottom respectively arranges a wet scrubber 5, and wet scrubber 5 adopts horizontal mode to arrange.Wet scrubber 5 is changed into by the horizontal traverse of multiple stage and vertically arranging on differing heights, reduce wet scrubber floor space, reduce initial cost, and wet scrubber 5 is vertically arranged so that elbow and is connected the minimizing of flue 7 consumption, elbow minimizing makes flue gas flow direction more smooth and easy, reduces flue resistance; Connect flue 7 and reduce saving rolled steel dosage, reduce costs.
Be provided with discharge casing 9 below each wet scrubber 5, the discharge outlet of each wet scrubber 5 is got up by placed in series and the outlet of pipeline is connected with discharge casing 9 entrance.Arranging discharge casing makes the water produced in wet scrubber 5 directly drain in discharge casing 9, and placed in series uses shorter pipeline than in parallel, and the below that discharge casing 9 is arranged in wet scrubber 5 simultaneously ensures that pipeline 10 consumption is minimum, practical and save.
