Description
[technical field]
The utility model relates to the arrangement of desulfuration absorbing tower, wet electrical dust precipitator and chimney, is specifically related to the arrangement of a kind of desulfurization and dedusting fume extractor in cooling stack.
[background technology]
Along with China more and more payes attention to environmental protection, pay special attention to the control of atmosphere pollution, the flue gas of coal-burning power plant is proposed to the requirement of ultra-clean discharge, after desulfuration absorbing tower, add one-level wet electrical dust precipitator is again one of solution.
Power plant desulfurization absorption tower, wet electrical dust precipitator and chimney are usually placed in outside cooling stack, there is application desulfuration absorbing tower or chimney are arranged in cooling stack in recent years, if but desulfuration absorbing tower, wet electrical dust precipitator, chimney are arranged sequentially in indirect cool tower by usual level, floor space is large, smoke canal elbow is many, smoke evacuation resistance is large, and power of fan is large, and then makes station service power consumption rate higher; Three kinds of equipment floor space in tower is large, affects cooling device in tower and arranges; When three kinds of equipment levels are arranged in tower, chimney is not in indirect cool tower center, and this arranged off-centre makes chimney emission increase the corroded area of cooling tower inwall.
[utility model content]
The utility model object is to overcome prior art defect, provides the arrangement of a kind of desulfurization and dedusting fume extractor in cooling stack, reduces investment outlay, reduces station service power consumption rate and plant area's occupation of land.
For achieving the above object, the technical solution adopted in the utility model is:
The arrangement of a kind of desulfurization and dedusting fume extractor in cooling stack, desulfurization and dedusting fume extractor comprises desulfuration absorbing tower, wet electrical dust precipitator and chimney, desulfuration absorbing tower, wet electrical dust precipitator and chimney are arranged vertically on the center of cooling stack from the bottom up successively, and the flue gas that boiler combustion produces is transported to desulfuration absorbing tower from cooling stack outside by flue.
Further, described cooling stack is gravity-flow ventilation indirect dry cooling tower or natural ventilating wet-type crossing current tower.
Further, described air flue horizontal is arranged.
Further, in described flue tower, part is connected to desulfuration absorbing tower, and tower outward part is erected on support, horizontal through cooling stack barrel.
Further, described flue distance ground certain altitude is arranged.
The desulfuration absorbing tower of power plant, wet electrical dust precipitator and chimney are arranged in cooling stack by the utility model, and three kinds of equipment are arranged vertically on tower center by order from low to high; Desulfuration absorbing tower is arranged in the bottom, and wet electric cleaner is arranged in middle part, and chimney is arranged in topmost, and three is arranged vertically within indirect cool tower center, and floor space is minimum, is conducive to the layout of cooling device, road etc. in cooling tower.
Chimney is positioned at centre of cooling column, makes the corroded area of chimney emission to indirect cool tower inwall minimum, saves anti-corrosion material, reduces investment outlay.After being arranged vertically, chimney emission mouth is lifted to higher height, effectively can utilize pressure reduction, and make exhaustion smoke height lifting, Pollutants Diffusion is effective.Flue, from level access desulfuration absorbing tower cooling tower, reduces flue bent pipe, makes flue distance the shortest, reduces smoke evacuation resistance, reduce power of fan, reduce station service power consumption rate.The fresh water (FW) of wet scrubber can enter in desulfuration absorbing tower and reuses by gravity current, reduces pipeline consumption.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1 and Fig. 2, the arrangement of desulfurization and dedusting fume extractor of the present utility model in cooling stack, desulfurization and dedusting fume extractor comprises desulfuration absorbing tower 6, wet electrical dust precipitator 7 and chimney 8, desulfuration absorbing tower 6, wet electrical dust precipitator 7 and chimney 8 are arranged vertically on the center of cooling stack 1 from the bottom up successively, and the flue gas that boiler combustion produces is transported to desulfuration absorbing tower 6 from cooling stack 1 outside by flue 5.
Desulfuration absorbing tower, wet electrical dust precipitator, chimney are arranged vertically within centre of cooling column position by the utility model, save the area, and reduce flue length and turning, reduce station service power consumption rate, reduce the corroded area of inner wall of tower, take up an area in Appropriate application tower.
Further, described cooling stack 1 is gravity-flow ventilation indirect dry cooling tower or natural ventilating wet-type crossing current tower.
Further, in described flue 5 tower, part is connected to desulfuration absorbing tower 6, and tower outward part is erected on support, horizontal through cooling stack barrel, radiator or filler 3 are arranged in cooling tower 1 lower periphery, radiator or sealed by broadening platform 2 between filler 3 top and indirect cool tower 1; Flue 5 is horizontally disposed with, and distance ground 4 certain altitude is arranged.
The utility model discloses a kind of desulfuration absorbing tower, wet electrical dust precipitator and the chimney method for arranging in cooling stack, wet electrical dust precipitator, desulfuration absorbing tower and chimney are arranged in cooling stack center by the method, make flue distance the shortest, in indirect cool tower, floor space is minimum, blast in tower is utilized to discharge fume to greatest extent, save the occupation of land outside tower of wet electrical dust precipitator, desulfuration absorbing tower and chimney, save land area on the whole.Cooling stack comprises gravity-flow ventilation indirect dry cooling tower and natural ventilating wet-type crossing current tower.
Above content is further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the protection domain of the utility model by submitted to claims determination utility model.
