Abstract
The utility model discloses a kind of wet electrical dust precipitator with counter-rotating spraying, wherein technique water pipe is positioned in the middle of vertical collecting plate, uniform sparking electrode below technique water pipe, described technique water pipe is provided with some atomization rotary nozzles, and its feature spray direction is contrary with flow of flue gas direction.The utility model has the advantages that: adopt the wet electrical dust precipitator ash-removal effect of reverse spraying excellent that there is the combined pollutant removal ability such as significant PM2.5, droplet and heavy metal more simultaneously.
Description
Technical field
The utility model belongs to environmental technology field, is specially a kind of wet electrical dust precipitator with reverse spraying.
Technical background
The main distinction of wet-esp and conventional dry electric precipitation is purge mode, and wet electrical dust precipitator is sprayed onto by water on collecting plate to form continuous print moisture film, and the dust of catching is washed in ash bucket and discharges with water by circulating water, therefore can not produce reentrainment of dust.Wet-esp has good removal effect to acid mist, toxic heavy metal and PM2.5 in addition.
Way general at present adopts shower nozzle to spray water toward collecting plate along flue gas direction, this purge mode will be that a kind of simple liquid film washes away principle: form continuous print liquid film at collecting plate, liquid film only serves as the effect of collecting plate, whether it has electric conductivity have strict demand to washing away liquid, secondly, the physical characteristic of liquid film and distribution situation are also very important.
Utility model content
The purpose of this utility model is to provide a kind of wet electrical dust precipitator with reverse spraying, has excellent deashing property, has the combined pollutant removal ability such as significant PM2.5, droplet and heavy metal more simultaneously.
In order to realize the problems referred to above, the utility model adopts following scheme to realize: a kind of wet electrical dust precipitator with counter-rotating spraying, comprise atomization rotary nozzle, technique water pipe, sparking electrode and collecting plate, described technique water pipe is positioned in the middle of vertical collecting plate, uniform sparking electrode below technique water pipe, described technique water pipe is provided with some atomization rotary nozzles, and the opening spray direction of described atomization rotary nozzle is vertically upward, contrary with flow of flue gas direction.
Further, the center line of every adjacent two collecting plates is provided with a technique water pipe, and the overhead height of described atomization rotary nozzle is lower than collecting plate overhead height, and difference in height is at 100mm-500mm.
Further, the spacing of adjacent two the atomization rotary nozzles each technique water pipe arranged is more than three times or three times of neighbouring discharge electrode spacing.
The utility model has the advantage of:
(1) oppositely spray compared with existing spray mode, there is more excellent deashing property and more obvious contaminant removal capacity, because oppositely first spraying forms one deck fog-zone above region of discharge, fog-zone can abundant wet granulate thing, strengthen charging particle ability, the droplet condensation be simultaneously sprayed on collecting plate forms uniform moisture film and flows downward, and fully charged dust and droplet move on collecting plate acting on of electric field force, flow into grey bucket with moisture film.
(2) adopt atomization rotary nozzle, due to its broad covered area, the usage quantity of shower nozzle can be greatly reduced, there is cost-saving advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of wet electrical dust precipitator with counter-rotating spraying of the utility model.
Fig. 2 is the A-A direction view of the structural representation of wet electrical dust precipitator.
Specific implementation method
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 and Fig. 2 is the case study on implementation of a kind of wet electrical dust precipitator with counter-rotating spraying of the utility model, a kind of wet electrical dust precipitator of counter-rotating spraying, wherein technique water pipe 2 is positioned in the middle of vertical collecting plate 4, uniform sparking electrode 3 below technique water pipe 2, described technique water pipe 2 is provided with some atomization rotary nozzles 1, its spray direction is sprayed vertically upward, contrary with flow of flue gas direction.Described technique water pipe 2 is located on the center line of two collecting plates 4, and the height of atomization rotary nozzle 1 is lower than collecting plate overhead height, and difference in height is at 100mm-500mm.The spacing of the atomization rotary nozzle 1 that each technique water pipe 2 is arranged is more than three times or three times of neighbouring discharge electrode 3 spacing, controls the formation of fog-zone and the formation of collecting plate surface moisture film by regulating injection flow rate.
This device is oppositely sprayed compared with existing spray mode, there is more excellent deashing property and more obvious contaminant removal capacity, because oppositely first spraying forms one deck fog-zone above region of discharge, fog-zone can abundant wet granulate thing, strengthen charging particle ability, the droplet condensation be simultaneously sprayed on collecting plate forms uniform moisture film and flows downward, and fully charged dust and droplet move on collecting plate acting on of electric field force, flow into grey bucket with moisture film.
Adopt rotary nozzle, due to its broad covered area, the usage quantity of shower nozzle can be greatly reduced, there is cost-saving advantage.
Above-described embodiment is only illustrate of the present utility model; but technical characteristic of the present utility model is not limited to this, any change that any those skilled in the art makes in field of the present utility model and modification are all encompassed within scope of patent protection of the present utility model.
