Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment, a kind of industrial refuse processing system deacidifying dedusting device, as shown in Figure 1, including the chilling being sequentially communicated
Tower 1, drying tower 2 and after-treatment tower 3, chilling tower 1 is interior to be equipped with cooling element 4, for flue dust to be made to cool down, avoids generating two again
Dislike English；4 lower section of cooling element is equipped with depickling component 5, for neutralizing the sour gas in flue dust.Dry dress is equipped in drying tower 2
It puts, for the flue gas of dry moistening；Calcium hydroxide and activated carbon are set in after-treatment tower 3, for after-treatment flue gas, is further taken off
Sour dedusting, purifying smoke.
1 top of chilling tower is equipped with entrance 21, and bottom is equipped with leakage fluid dram 8.The flue dust of high temperature is entered by entrance 21 from top
Chilling tower 1 carries out depickling dedusting then in turn through cooling element 4 and depickling component 5, is then emitted by leakage fluid dram 8.
Cooling element 4 includes chilling tower water tank 15,14 and second high pressure nozzle 13 of cold water delivery pipe, and the second high pressure nozzle 13 is to chilling tower
Water spray in 1 so that flue dust instantaneous temperature reduction is to 200 °C, while under hydraulic pressure effect, and grit is settled down to tower body, convenient for one
It is transferred out with by leakage fluid dram 8.Depickling component 5 includes 6 and first high pressure nozzle 7 of lye delivery pipe, and lye delivery pipe 6 is along urgency
Cold pipe internal helicoid distribution, the first high pressure nozzle 7 are evenly distributed in lye delivery pipe 6 so that lye is sprayed in chilling tower 1
Each region, avoid flue dust flowing velocity fast, it is impossible to fully with lye carry out neutralization.
In order to recycle lye, cost is reduced, lye water circulation tank 9, lye water circulation tank are equipped with outside chilling tower 1
The leakage fluid dram 8 of 9 sides connection chilling tower 1, lye is delivered in chilling tower 1 by opposite side connection lye delivery pipe 6 again to carry out
Neutralization.
Since the lye that leakage fluid dram 8 exports is diluted by cold water and is mingled with grit, in order to improve lye, in lye water circulation tank
Partition board 10 is set gradually according to sequence in 9, forms chamber 11 not of uniform size between adjacent partition board 10, lye is from minimum
Chamber 11 be discharged into lye water circulation tank 9, lye is precipitated by chamber 11, grit is separated one by one；Lye is from most
Big chamber 11 is expelled to chilling tower 1, and by repeatedly precipitating, lye is minimum containing grit in maximum chamber 11.In order to improve alkali
The alkalinity of liquid, maximum chamber 11 connect with outside and supplement pipe 12 with lye, improve the alkalinity in lye water circulation tank 9, strengthen
Depickling function.
Moistening flue gas through 1 first depickling dust removal process of over-quenching tower enters drying tower 2 and processing, drying device is dried
Including flue gas burner 16, evaporate vapor for heating flue gas.
In order to extend residence time of the flue gas in drying tower 2, make vapor fully dry, rotation is equipped in drying tower 2
