Background technique
In last century mid-term, 80 or more percent sulphur is consumed in the form of sulfuric acid, in addition sulfur dioxide sheet
The intrinsic physics of body, chemical property, it is manufacture sulfuric acid that the most economical method of sulfur dioxide is recycled from flue gas during smelting.Around this
One project carries out the technological improvement of smelting technology, experienced very very long development process.Utilize the pass of sulphur dioxide flue gas acid preparing
Key problem is the concentration of sulfur dioxide in flue gas.From technical theory at this stage, sulfur dioxide concentration also can down to 0.2 ~ 0.3%
Relieving haperacidity, so concentration problems are not technical problems, emphasis is economic problems.
Currently, existing acid-making process has conventional indirect acid-making process and direct acid-making process and high gauge
LUREC technique, pre reforming Process etc., but these techniques have an identical point, are exactly the high cost and acid manufacturing processes of equipment
Cumbersome process, at present, the economic benefit of these techniques is not high.
Summary of the invention
In view of above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide the tail gas two of a kind of low cost, high benefit
Sulfur oxide relieving haperacidity recovery system.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
The present invention is a kind of tail gas sulphur dioxide relieving haperacidity recovery system, has sequentially connected gas access, exhaust gases passes, high pressure
Pond, the high pressure pond top have water supplement port, and high pressure basin bottom is provided with several ejectors, the water outlet of the ejector
End is located in conversion pool.
Ejector two sides of the invention are respectively liquid inlet and oxygen intake, and it is molten to be configured with hydrogen peroxide in conversion pool
Liquid, conversion pool lower part are connect by conduit with liquid inlet.
Oxygen intake of the invention connects oxygen storage device by conduit.
Conversion pool top of the invention is provided with several spray heads, and solution is extracted by water pump in conversion pool lower part, until conversion
The spray head on pond top is sprayed.
Conversion pool top of the invention is provided with fluid infusion.
Conversion bottom of pond portion of the invention is provided with the outlet of sulfuric acid liquid, and the outlet of sulfuric acid liquid is configured with valve.
PH detector is configured in conversion pool of the invention.
Implement to recycle relieving haperacidity present invention is mainly used for tail gas sulphur dioxide, sulfur dioxide is crossed water formation sulfurous acid and penetrated
Stream combines hydrogen peroxide and oxygen quickly to aoxidize and sulfuric acid is made in jet process, and the present invention uses physical transfer, is shifting
Chemical reaction is completed in journey, converting apparatus is at low cost, and efficiency is fast, high efficiency, is suitble to industrial production.
Detailed description of the invention:
Fig. 1 is to be related to structural schematic diagram of the invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Shown in referring to Fig.1, a kind of tail gas sulphur dioxide relieving haperacidity recovery system has sequentially connected gas access 1, flue gas
Channel 2, high pressure pond 3 have water supplement port 31 above the high pressure pond 3, and 3 bottom of high pressure pond is provided with several ejectors 4,
The water outlet of the ejector 4 is located in conversion pool 5.Tail gas sulphur dioxide enters exhaust gases passes 2 from gas access 1, by cigarette
Enter in high pressure water pond 3 behind gas channel 2 and formation sulfurous acid soluble in water, under the pressure of water-head, the Asia of 3 bottom of high pressure pond
Sulfuric acid sprays downwards from ejector 4, into the conversion reaction for completing sulfuric acid in conversion pool 5 with hydrogenperoxide steam generator.
Specifically, 4 two sides of ejector are respectively liquid inlet 41 and oxygen intake 42, peroxidating is configured in conversion pool 5
Hydrogen solution, 5 lower part of conversion pool are connect by conduit with liquid inlet 41, under the negative pressure sucking effect of ejector 4, conversion pool 5
In hydrogenperoxide steam generator can be entered ejector 4 and sulfurous acid hybrid reaction by siphon, part forms sulfuric acid, and then mixed liquor sprays
Enter in conversion pool 5, conversion pool 5 belongs to semitight pond body, and 4 end of ejector enters in conversion pool 4, the sulfurous acid sprayed and portion
The hydrogenperoxide steam generator for dividing the sulfuric acid solution of conversion to contact large area before decomposition, and reaction is completed at once.
Since hydrogenperoxide steam generator amount is more, completely reaction before, need to persistently make hydrogenperoxide steam generator and constantly
The sulfurous acid of ejection comes into full contact with, and therefore, 5 top of conversion pool is provided with several spray heads 51, and 5 lower part of conversion pool passes through water pump 7
Solution is extracted, until the spray head 51 on 5 top of conversion pool is sprayed, the position of spray head 51 should be above the water outlet of ejector 4
From the fan-shaped ejection of spray head 51, the hydrogenperoxide steam generator that multiple spray heads 51 spray forms water curtain for end, i.e. hydrogenperoxide steam generator
The mixed liquor that covering ejector 4 is sprayed down, can not only accelerate to react, and can inhibit sulfitolysis.
In order to further speed up the relieving haperacidity reaction of sulfurous acid, oxygen intake 42 connects oxygen storage device 6 by conduit, is penetrating
So that most of sulfurous acid is completed relieving haperacidity reaction during stream, accelerates transformation efficiency.
PH detector 10 is configured in conversion pool 5, multiple, inspection can be arranged in PH detector 10 in 5 lengthwise position of conversion pool
The pH value for surveying different level solution, for detecting the pH value of mixed liquor in conversion pool 5, since hydrogen peroxide belongs to faintly acid,
PH value is about 4-5, and reacts the pH value of resulting dilute sulfuric acid between 0-2, and as dilute sulfuric acid concentration is higher, pH value is smaller.
Therefore, when detecting pH value less than 1, the solution inside conversion pool 5 can be released.Specifically 5 bottom of conversion pool is provided with sulfuric acid
Liquid outlet 9, and sulfuric acid liquid outlet 9 is configured with valve 91, magnetic-type electrically operated valve can be used in valve 91.
During sulfuric acid is discharged, it should be conversion pool 5 and supplements hydrogenperoxide steam generator, therefore 5 top of conversion pool is arranged
There is fluid infusion 8, it can real-time make-up solution.
In addition, if into exhaust gases passes 2 tail gas be high-temperature tail gas, can exhaust gases passes 2 in high pressure pond 3 just on
Side is arranged condenser 21, cools down to the high-temperature tail gas of process, water formed in cooling procedure is fallen into high pressure pond 3.
Exhaust gases passes 2 should be inserted directly into 3 bottom of high pressure pond simultaneously, so that sulfur dioxide gas is completely dissolved in water, and can lead to
Ejector 4 is crossed quickly to be discharged.
5 pressure of conversion pool is too high in order to prevent, one section of exhaust up extended can be arranged in the side wall of 5 lowest part of conversion pool
Mouth 58, is discharged other inert gases contained in tail gas sulphur dioxide, and can work normally ejector 4.
It should be understood that the technical scope of the present invention is not limited to the contents of the specification, it is general to this field
For logical technical staff, it can be modified or changed according to the above description, and all these modifications and variations all should belong to this hair
