Row, the problem of causing the discharge beyond standards of fluoride, there is provided the exhaust treatment system in a kind of glass furnace production, can avoid straight
A large amount of steam can be produced by connecing spraying cooling cooling pretreatment, both influence the absorbing and removing of waste gas containing fluoride, while the fluorination in tail gas
Thing grit carries the outer situation generation arranged, cause the discharge beyond standards of fluoride secretly by a large amount of steam.
2nd, the utility model sets two-stage to cool before tail gas enters defluorinate tower：One-level cooling uses preheater, through with it is cold
Follow-up system is sent into after air heat-exchange cooling；Two level cools in washing section, and cleaning solution is contacted into cooling with tail gas by spray gun.Two
Level cooling avoids direct spraying cooling cooling pretreatment from producing a large amount of steam, has both influenceed the absorbing and removing of waste gas containing fluoride, simultaneously
Fluoride grit in tail gas by a large amount of steam carry secretly it is outer arrange, the problem of causing the discharge beyond standards of fluoride.
3rd, in the utility model, after the preheated device of tail gas, temperature is also in higher state, because defluorinate tower is rubber-lining equipment,
It is directly entered in tower, tower line with rubber will necessarily be caused to damage as exhaust temperature is too high, therefore reducing temperature twice must be carried out to tail gas.Tail
After the preheated device of gas, L-type washer is initially entered, in L-type washer vertical cylindrical part, the de- of at least two layers different height is set
Fluorine tower spray gun.Supernatant in milk of lime underground tank is delivered to defluorinate tower spray gun by washer circulating pump, after the atomization of defluorinate tower spray gun
Washer is sent into, tail gas is contacted in washer with atomized liquid, and exhaust temperature is reduced into suitable inlet temperature of stabilizer, while right
Tail gas carries out pre-absorption.In the horizontal tubular section of L-type washer, temperature detection can be set, monitor tail gas inlet temperature of stabilizer in real time, together
When to enter defluorinate tower tail gas carry out water conservancy diversion.
4th, the utility model is preferable, the horizontal tubular elements along the tangent line of circle where the defluorinate tower cross section with it is described
Defluorinate tower connects.The said equipment connected mode is selected, process gas flow can be made to form cyclonic separation state in defluorinate tower, to increase
Fluoride Separation effect in aerating stream.
5th, in the utility model, using preheater, avoid cold air being directly added into tail gas is cooled, and then increase
Vent gas treatment amount, cause follow-up defluorinate systematic lectotype to increase, increase first cost of investment.Preheater is set up, by being incited somebody to action after heat exchange
Exhaust temperature control is produced in certain temperature, so as to avoid tail gas from being passed directly into defluorinate system, direct spraying cooling cooling processing
Raw a large amount of steam, influence the absorbing and removing of waste gas containing fluoride, while it is outer to avoid the fluoride grit in tail gas from being carried secretly by a large amount of steam
Row, the problem of causing the discharge beyond standards of fluoride.
6th, in the utility model, at least two layers of different height, and washer spray gun staggeredly is set in washer, will be circulated
Clear liquid is by being pumped into washer spray gun；The cleaning solution that washer spray gun is sprayed, which can accumulate washer inner section, all to be covered
Lid, so as to carry out reducing temperature twice and pre-absorption to flue gas.Set from top to bottom in defluorinate tower at least two layers, and defluorinate tower staggeredly
Spray gun, defluorinate tower spray gun is sent into after slurries in tower are pumped out by circulation, has and selects the spies such as area coverage is wide, atomizing effect is good
Point, fully hydrogen fluoride in flue gas can be absorbed, ensure higher removal efficiency.
7th, in the utility model, wash tub pipe is set, and its object is to prevent demister fouling to block up above defluorinate tower spray gun
Plug.After defluorinate tower runs a period of time, wash tub pipe valve can be opened, 5-10 minutes are rinsed to demister, is easy to take off
Fluorine tower normal table is run.
8th, in the utility model, tower bottom can be deposited in, it is necessary to set stirring to fill by reacting the bulky grains such as the calcirm-fluoride of generation
Put, avoid particulate matter from being accumulated in bottom of towe.Because the tower diameter of most defluorinate tower is too small, agitator is such as set, agitator will be unable to install.
Therefore aerator is set in bottom of towe, liquid is remained certain mixed flow state by being sent into compressed air, pass through the liquid of bottom of towe the 3rd
Thick slurry subsider is sent into body outlet, and by three-level natural subsidence, solids particles precipitate, supernatant returns to milk of lime underground tank.For
It is too high to avoid holding liquid liquid level in tower, sets second liquid to export above aerator, i.e. overfall, by superelevation liquid level liquid flooding
To milk of lime underground tank.
9th, in the utility model, bottom of towe loop slurry contacts through circulating pump, defluorinate tower spray gun with tail gas, will be fluorinated in tail gas
Thing absorbing and removing, loop slurry temperature increase., need to be by loop slurry temperature to ensure that fluoride has higher removal efficiency
Reduce.System sets shell-and-tube heat exchanger, and defluorinate tower slurries out first pass around shell-and-tube heat exchanger out of tower through circulating pump, lead to
Cross and exchanged heat with cooling circulating water, cool the temperature to certain temperature, be re-fed into defluorinate tower top defluorinate tower spray gun and enter in tower,
Ensure that loop slurry is in higher absorption efficiency all the time.
10th, in the utility model, multiple baffle demister is provided with chimney, the moisture in final discharge flue gas can be removed,
So as to reduce discharge capacity.
