Description
Technical field
The utility model relates to sulfur-containing tail gas processing equipment field, at especially a kind of tail gas of high-sulfur comprehensive utilization of tailing
Manage device.
Background technique
High-sulfur tailing mainly contains diaspore, pyrite and a small amount of gangue mineral, from molecular structure mainly
Aluminum silicon mineral and pyrite all have unique mineral attribute, all can be used as effective adsorbent and water purification agent after treatment,
For this purpose, laboratory is with " treatment of wastes with processes of wastes against one another ", theory is set out, function modified to the progress of high-sulfur tailing, so that it is useless to obtain a kind of efficient process
The cleanser of water.And the property of desulfurization tailing itself reacts with hydrochloric acid under certain condition containing aluminium ferrosilicon, generates poly-
Aluminium iron silicate is closed, water can not only be purified, but also be the secondary effective use of resource, becoming a kind of has high added value
Product, increase enterprise profit.
But the toxic tail gas such as hydrogen sulfide and sulfur dioxide, especially hydrogen sulfide are inevitably generated in production process, is
A kind of inflammable sour gas, colourless, there is rotten egg smell in when low concentration, just there is stink when concentration is extremely low, severe toxicity, therefore to tail
Gas has to be handled, and mostly uses tail gas to be passed directly into strong caustic at present and is absorbed, but because of high-sulfur tailing sulphur
Content is more, and the absorption of hydrogen sulfide is incomplete, and gas is passed directly into solution, and impact force is larger, and bulk gas is because reacting not
It escapes completely, endangers environment.For this reason, it may be necessary to be improved to the absorption plant of hydrogen sulfide, SO 2 tail gas.
Summary of the invention
The purpose of this utility model, which is that, overcomes above-mentioned deficiency, provides a kind of vent gas treatment of high-sulfur comprehensive utilization of tailing
Device.
In order to achieve the above objectives, the utility model is implemented according to following technical scheme:
A kind of exhaust gas processing device of high-sulfur comprehensive utilization of tailing, including tail gas absorption tank, air inlet pipe, in tail gas absorption tank
It is provided with sodium hydroxide solution, partition is provided in the tail gas absorption tank, tail gas absorption tank is split up into two connections by partition
Left chamber, right chamber, the air inlet pipe is provided with coiled pipe in left chamber, and left chamber top passes through exhaust tube, aspiration pump
Be connected to right chamber, exhaust tube is also equipped with coiled pipe in right chamber, the coiled pipe be placed in inside sodium hydroxide solution and
It is provided with venthole, the top of the right chamber is provided with escape pipe；The tail gas absorption tank is in the lower section of sodium hydroxide solution
It is provided with inlet, detection mouth, liquid outlet, inlet, detection mouth, liquid outlet are provided with ball valve.
Further, the outside of coiled pipe is arranged in the venthole.
Further, barometer, air outlet valve are disposed on the escape pipe.
Compared with prior art, the utility model increases tail gas and sodium hydroxide solution by the venthole of coiled pipe
Contact area, be effectively relieved the impact force of gas, increase the reaction time of solution and gas, thus efficient process high-sulfur
Tail gas absorption is led to the problem of during comprehensive utilization of tailing；By the setting of partition, exhaust tube, aspiration pump so that failing completely anti-
Hydrogen sulfide, the sulfur dioxide gas answered re-start secondary response, enable tail gas abundant in excessive sodium hydroxide solution
Reactive absorption；Because hydrogen sulfide, sulfur dioxide gas can sufficiently be reacted in excessive sodium hydroxide solution, arranged without excessive gas
Out, so observation barometer can be with the pressure value in observation device, then pass through detection mouth and the concentration of sodium hydroxide solution is carried out
Detection, replaces sodium hydroxide solution in time, guarantees the continuity of vent gas treatment；Hydrogen sulfide, sulfur dioxide gas and excessive hydrogen
Vulcanized sodium, the sodium sulfite that sodium hydroxide solution reaction generates can extract recycling.
The utility model has the following beneficial effects: sufficiently being fully absorbed to the tail gas after high-sulfur comprehensive utilization of tailing, subtract
The discharge of few pollutant；It ensure that the safety of working environment；Vulcanized sodium, sodium sulfite after absorption in waste liquid can extract
It recycles.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of coiled pipe venthole.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings and specific embodiments, in the signal of this utility model
Property embodiment and explanation be used to explain the utility model, but be not intended to limit the scope of the present invention.
A kind of exhaust gas processing device of high-sulfur comprehensive utilization of tailing as shown in Figure 1 and Figure 2, including tail gas absorption tank 1, into
Tracheae 10 is provided with sodium hydroxide solution 2 in tail gas absorption tank, is provided with partition 3 in the tail gas absorption tank, and partition is by tail gas
Tourie 1 is split up into the left chamber 15 of two connections, right chamber 16, and the air inlet pipe is provided with coiled pipe 4 in left chamber, left
Chamber top is connected to by exhaust tube 9, aspiration pump 8 with right chamber, and exhaust tube is also equipped with coiled pipe, the snake in right chamber
Shape pipe is placed in inside sodium hydroxide solution and is provided with venthole 17, and the top of the right chamber is provided with escape pipe 6；The tail
Aspiration closed cans is provided with inlet 11, detection mouth 12, liquid outlet 13 below sodium hydroxide solution, and inlet, goes out detection mouth
Liquid mouth is provided with ball valve 14.
The outside of coiled pipe is arranged in venthole 17；Barometer 7, air outlet valve 5 are disposed on escape pipe.
When the utility model is used, the tail gas after high-sulfur comprehensive utilization of tailing enters tail gas by air inlet pipe, coiled pipe
In tourie, the venthole of coiled pipe reduces the impact force of tail gas, and increases the contact area with sodium hydroxide solution；Not
The tail gas sufficiently reacted escapes into the top of left chamber, and by the effect of exhaust tube, aspiration pump, it is anti-again to enter right chamber
It answers；Air outlet valve can be suitably opened according to the concentration of sulfur dioxide in tail gas, hydrogen sulfide, discharge cannot be reacted with sodium hydroxide solution
Gas；If observation barometer discovery air pressure continues to increase, tail gas entrance can be stopped, sodium hydroxide solution is detected by detection mouth
Concentration, when needing concentration too low, by the drain of liquid outlet, the feed liquor of inlet completes the addition of sodium hydroxide solution, into
And restart the absorption of tail gas.
The limitation that the technical solution of the utility model is not limited to the above specific embodiments, all skills according to the present utility model
The technology deformation that art scheme is made, each falls within the protection scope of the utility model.
