Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is schematic diagram of the invention；
Fig. 2 is the schematic diagram of level-one wet process tower of the present invention；
Fig. 3 is the schematic diagram of second level wet process tower of the present invention；
Fig. 4 is the schematic diagram of wire mesh demister of the present invention.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figs 1-4, wet process deacidification system, including air-introduced machine 1, level-one wet process tower 2 and second level wet process tower 3, air-introduced machine 1
Level-one wet process tower 2 is connected by flue 4, level-one wet process tower 2 connects second level wet process tower 3 by flue 4, and flue gas is taken out by air-introduced machine 1
It is fed into level-one wet process tower 2, level-one wet process tower 2 carries out first time processing to flue gas, discharge treated waste liquid, remaining flue gas
Enter second level wet process tower 3 by flue 4, second is carried out to flue gas and is handled, discharge treated waste liquid.
Level-one wet process tower 2 includes the first tower body 21, and the smoke inlet 22 of the first tower body 21 is located at the lower part of the first tower body 21,
The exhanst gas outlet 23 of first tower body 21 is located at the top of the first tower body 21, and 21 internal upper part of the first tower body is vertically provided with several
One spraying layer 24, the first spraying layer 24 connects the depickling liquid cooling bay outside the first tower body 21 by pipeline, from depickling liquid cooling bay
Middle extraction cold water is sprayed into the first tower body 21.
Sieve plate 25 is installed, sieve plate 25 is fixedly connected with the first tower body 21 below each first spraying layer 24.
Second level wet process tower 3 includes the second tower body 31, and 31 lower part of the second tower body is provided with secondary flue gas entrance 32, secondary flue gas
Several orifice plates 33 and several second spraying layers 34, the second spray of the top are arranged at intervals in second tower body 31 of 32 top of entrance
It is provided with several flushing layers 35 above drenching layer 34, rinses and is equipped with Flat defroster 36 between layer 35, on Flat defroster 36
Side is equipped with wire mesh demister 37.
Since with Flat defroster 36 and wire mesh demister 37, second level wet process tower 3 can either remove biggish droplet,
Also short grained droplet and aerosol can be removed, removal effect is good, and traditional wet process tower is to aerosol and little particle mist
The removal effect of drop is poor, and removal effect is undesirable.
Wire mesh demister 37 includes annular lower supporting plate 371 disposed in parallel and annular upper backup pad 372, the lower support of annular
Silk screen 373 is connected between plate 371 and annular upper backup pad 372.
Annular 371 bottom of lower supporting plate is connected with the supporting beam 374 by the center of circle, and 374 bottom of supporting beam is connected with along branch
Support the vertical gusset 375 that beam 374 is arranged.
The sieve plate 25 of bottom is made of 2205 stainless steels, using its high temperature resistance, is resistant to the high temperature of flue gas, protects
Hold enough service life.
21 inner wall of the first tower body of 25 lower section of bottom sieve plate is provided with pyroceram scale.
There are two entrances 5, an entrance 5 to spray into atomized water using double-current spray gun body, be used to cigarette for setting on flue 4
Gas cools down, another entrance 5 uses screw conic nozzle, method waste liquid or water is squirted to 4 inner wall of flue, to 4 siding of flue
Cool down, protects pyroceram scale, influence its antiseptic property by the high temperature of flue gas.
The present invention carries out multiple depickling by level-one wet process tower and second level wet process tower, to flue gas, and level-one wet process tower removes cigarette
Most of sour gas in gas reduces the consumption of water so that most sulphur is discharged from level-one wet process tower in flue gas, and two
Grade wet process tower removes the sour gas in remaining flue gas, and salt content substantially reduces from the liquid being discharged in second level wet process tower, takes off
Acid is more thorough, so that the longer life expectancy that the heat exchanger connecting with second level wet process tower can be used, while meeting current demand, together
When, since the salinity of circulation fluid in second level wet process tower is lower than the salinity in level-one wet process tower, second level wet process tower is interior to be taken to by flue gas
Salinity in the droplet of follow-up steam heater is low, can extend steam heater service life, strengthen and add to follow-up steam
The protection of hot device system.
It is above-mentioned according to the present invention for enlightenment, through the above description, relevant staff completely can without departing from
