Description
【Technical field】
This utility model is related to the arrangement of desulfuration absorbing tower, wet electrical dust precipitator, chimney and cooling stack,
The horizontal arrangement of desulfurization and dedusting smoke extractor in specifically related to a kind of cooling stack.
【Background technology】
As China increasingly payes attention to environmental conservation, the control to atmospheric pollution is more and more stricter, and environmental administration is to combustion
The flue gas of coal-fired plant proposes the requirement of ultra-clean discharge, after desulfuration absorbing tower humidification-type electric cleaner be solution it
One.Desulfuration absorbing tower, wet electrical dust precipitator, chimney and cooling stack belong to different monomers building.It is in recent years section
About land used, each construction of structures of power plant requires to merge arrangement as far as possible, to optimizing plant area's floor space, reduces investment.
【Utility model content】
The purpose of this utility model is to overcome prior art defect, there is provided desulfurization and dedusting in a kind of cooling stack
The horizontal arrangement of smoke extractor, with reference to specific engine request, by desulfuration absorbing tower, wet electrical dust precipitator, chimney with it is cold
But tower is combined arrangement, reduces investment outlay and plant area's floor space.
To reach above-mentioned purpose, this utility model is adopted the following technical scheme that：
The horizontal arrangement of desulfurization and dedusting smoke extractor in a kind of cooling stack, desulfurization and dedusting smoke extractor bag
Desulfuration absorbing tower, wet electrical dust precipitator and chimney are included, desulfuration absorbing tower, wet electrical dust precipitator and chimney level are sequentially arranged in certainly
So in aerating and cooling tower, flue is connected in desulfuration absorbing tower through cooling stack level, and boiler combustion is discharged fume from flue
Directly in desulfuration absorbing tower, the desulfurization of Jing absorption towers is entered and go in wet electrical dust precipitator smoke abatement, most after Jing chimneys discharge.
Further, cooling stack includes gravity-flow ventilation indirect dry cooling tower and natural ventilating wet-type crossing current tower.
Further, chimney is located at cooling stack center or near tower center.
Further, using 90 ° of bend pipe arrangements in tower, material is steel pipe to chimney, and length is about 16m.
Further, wet electrical dust precipitator and chimney are fixed in cooling stack using steel support structure.
Desulfuration absorbing tower, wet electrical dust precipitator and chimney are arranged horizontally in successively cooling stack by this utility model
It is interior.Using the exhaustion smoke height of the natural air lifting chimney of cooling tower, chimney stack is changed into into short chimney, the civil engineering for saving chimney is thrown
Rate are used, and shorten the chimney construction period, while reaching the environmental requirement of fume emission height and diffusion.
This utility model has further the advantage that：
1st, the desulfuration absorbing tower of power plant, wet electrical dust precipitator and chimney are arranged in cooling stack, three kinds set
Standby to press horizontally disposed successively in tower, smoke evacuation technique is smooth rationally, according to the arrangement height of flue, chimney emission level is connected to
In desulfuration absorbing tower, chimney turning path is reduced, make flue distance most short, reduce smoke evacuation resistance, reduce power of fan, reduce factory
Power consumption rate.
2nd, chimney is located at centre of cooling column or near tower center, makes corroded area of the chimney emission to indirect cool tower inwall
Minimum, saves anti-corrosion material, reduces investment outlay.
3rd, chimney is arranged in cooling tower, can air pressure difference in effectively utilizes tower, make exhaustion smoke height lifting, pollutant diffusion
Effect is good.When tower trunk of funnel is individually arranged, chimney structure is built-in steel pipe reinforced concrete enveloped structure, highly about 180m～
210m.Chimney 90 ° of bend pipe arrangements in tower, material is steel pipe, and length is about 16m.The chimney section arranged in tower outside relative to tower
About the civil engineering costs such as steel and concrete, reduce investment outlay, while dramatically shortening the construction period of chimney.
4th, the fresh water (FW) of wet electrical dust precipitator can gravity stream reused in desulfuration absorbing tower, reduce pipeline use
Amount.

【Specific embodiment】
It is right below in conjunction with the accompanying drawings in order to clearer explanation this utility model implements technological means, the creation characteristic of realization
This utility model is further elaborated.
As depicted in figs. 1 and 2, in cooling stack desulfurization and dedusting smoke extractor horizontal arrangement, desulfurization removes
Dirt smoke extractor includes desulfuration absorbing tower 2, wet electrical dust precipitator 3 and chimney 4, desulfuration absorbing tower 2, wet electrical dust precipitator 3 and cigarette
The level of chimney 4 is sequentially arranged in cooling stack 1, and flue 5 is connected to desulfuration absorbing tower through the level of cooling stack 1
In 2, boiler combustion is discharged fume from flue 5 directly in desulfuration absorbing tower 2, Jing after the desulfurization of absorption tower, in entering wet electrical dust precipitator 3
Remove smoke abatement, most after Jing chimneys 4 discharge.
In arrangement of the present utility model, flue, desulfuration absorbing tower, wet electrical dust precipitator, air flue horizontal arrangement, construction
When can respectively be constructed according to equipment arrival situation, final physical connection, the construction and installation between each device are independent of each other.Cigarette
Road is accessed nearby in desulfuration absorbing tower from the outer level of cooling tower, reduces flue bent pipe, makes flue distance most short, reduces smoke evacuation resistance
Power, reduces power of fan, reduces station service power consumption rate.The fresh water (FW) of wet scrubber can gravity stream carry out in desulfuration absorbing tower weight
It is multiple to utilize, reduce pipeline consumption.
Cooling stack 1 includes gravity-flow ventilation indirect dry cooling tower and natural ventilating wet-type crossing current tower.Chimney 4 is located at certainly
The right center of aerating and cooling tower 1 or close tower center.Using 90 ° of bend pipes arrangement in tower, material is steel pipe to chimney 4, length
About 16m.Wet electrical dust precipitator 3 and chimney 4 are fixed in cooling stack 1 using steel support structure 6.
