Abstract
The utility model discloses a tail gas purification device which is suitable for removing the sulfureted hydrogen in the waste gas of the exhaust tower. The device takes the exhaust tower and the inlet airway as desulfurization equipment and has an absorption liquid circulatory system including a spray device, a circulatory trough and a circulatory pump to make the tail gas entering the tower contact and react with the adsorption liquid, absorb the sulfureted hydrogen in the waste gas and exhaust the tail gas after purification; for avoiding the secondary pollution, an absorption liquid degassing system consisting of a degassing tank, a vacuum pump, a degassing pump and an acid trough, the absorption liquid degassing system replaces the sulfureted hydrogen for reuse; a majority of the absorption liquid is for circulatory use and the minority for the degassing treatment. The utility model handles a large quantity of waste gas, and has a high efficiency of desulfurization, low operation cost, low investment, obvious social benefit, environment benefit and economic benefit.
Description
Technical field
The utility model relates to a kind of waste gas purification apparatus, particularly relates to a kind of purifier of exhaust tower discharging waste gas.
Background technology
Viscose rayon manufacturing enterprise will produce a large amount of waste gas, wherein contain pernicious gases such as hydrogen sulfide, the partly existing processing method preferably of high concentration in these waste gas, the low concentration part is because its total amount is bigger, handle difficulty, domestic enterprise does not all handle, and adopts exhaust tower to carry out high altitude discharge, dilution, but because wherein pernicious gas still can not be diluted to harmless concentration range when being deposited to ground, people are lived produces certain influence.
Summary of the invention
The utility model aim to provide a kind of investment cost low, handle large-minded, remove the waste gas purification apparatus that the hydrogen sulfide effect is obvious, operating cost is low, reduce the discharge capacity of hydrogen sulfide effectively.
Key of the present utility model is with exhaust tower, exhaust tower wind inlet channel itself is as desulphurization plant, and be equipped with and comprise spray equipment, dosage bunker, circulating slot, the absorption liquid circulatory system of circulating pump, the waste gas that enters in the tower is contacted with absorption liquid, and react, to discharge behind the waste gas purification: the absorption liquid major part that has absorbed hydrogen sulfide recycles, fraction is discharged, for avoiding secondary pollution, the absorption liquid of discharging enters by degassing tank, vavuum pump, the absorption liquid degas system that degassing pump and acid tank are formed, absorption liquid and acid liquid reaction cement out hydrogen sulfide in degassing tank.In degassing tank, finish reacted wastewater and enter sewage disposal system from the degassing tank discharge; The hydrogen sulfide that cements out utilizes again, can make refining hydrogen sulfide or send into sulfuric acid plant as raw material, also can send into other desulphurization system and be translated into solid sulphur.
Description of drawings
Fig. 1 is the device schematic diagram of the utility model (spray equipment is installed in exhaust tower inside).
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
1. exhaust towers among the figure, 2. exhaust tower wind inlet channel, 3. spray equipment, 4. degassing pump, 5. degassing tank, 6. acid tank, 7. vavuum pump, 8. circulating slot, 9. circulating pump, 10. dosage bunker, 11. the import of degassing tank absorption liquid, 12. degassing tank acid solution imports, 13. degassing tank negative pressure mouths, 14. the hydrogen sulfide storage tank, 15. degassing tank discharging tubes.
With reference to Fig. 1,1 is exhaust tower, portion is equipped with spray equipment 3 within it, spray equipment 3 links to each other through the outlet of circulating pump 9 with circulating slot 8 bottoms, the drain pipe of exhaust tower 1 bottom is divided into two-way, one the tunnel links to each other with the import on circulating slot 8 tops, another road links to each other with the absorption liquid import 11 on degassing tank 5 tops through degassing pump 4, the air entry of vavuum pump 7 links to each other with the negative pressure mouth 13 at degassing tank 5 tops, the liquid outlet of acid tank 6 links to each other with the acid solution import 12 on degassing tank 5 tops, the exhaust outlet of vavuum pump 7 links to each other with the import of hydrogen sulfide storage tank 14, and the bottom of degassing tank 5 is provided with discharging tube 15, and the outlet of dosage bunker 10 links to each other with circulating slot 8.
During the device operation, waste gas enters exhaust tower 1 via exhaust tower wind inlet channel 2, contacts and remove most of hydrogen sulfide with absorption liquid, enters atmosphere by cat head then; Desulfurizing agent is (as NaOH, sodium carbonate or other alkaline solution etc.) and water allocate into by a certain percentage in the dosage bunker 10, utilize potential difference to flow automatically to circulating slot 8, transport to spray equipment 3 through circulating pump 9 and spray into formation drop in the exhaust tower 1, drop absorbs the most of hydrogen sulfide in the waste gas, the gravitate drop is fallen the bottom of exhaust tower 1 and is discharged by the drain pipe of exhaust tower 1 bottom, wherein major part enters circulating slot 8 and recycles, fraction is transported in the degassing tank 5 through degassing tank absorption liquid import 11 by degassing pump 4, absorption liquid reacts with the acid solution of being sent to through degassing tank acid solution import 12 by acid tank 6 in degassing tank 5, the hydrogen sulfide gas that reaction generates enters hydrogen sulfide storage tank 14 through degassing tank negative pressure mouth 13 by vavuum pump 7 and deposits temporarily, and absorption liquid and the acid solution waste water after degassing tank 5 internal reactions are finished is discharged by the discharging tube 15 of degassing tank 5 bottoms and entered sewage disposal system.
For the utility model, spray equipment 3 must adopt version preferably, and the drop in the time of could guaranteeing spray is less, and absorption liquid has bigger specific area, and through evidence, it is comparatively suitable that spray equipment 3 adopts atomizer; When spray equipment 3 adopted atomizer, desulfurized effect can be greater than 95%.
Spray equipment 3 can be installed in the exhaust tower wind inlet channel 2.
Spray equipment 3 can be installed in exhaust tower 1 and the wind inlet channel 2 thereof simultaneously.
If the negative pressure that vavuum pump 7 produces can suck the absorption liquid of q.s in the degassing tank 5, can be with 4 cancellations of degassing pump.
Because waste gas purification apparatus of the present utility model adopts exhaust tower and wind inlet channel thereof as desulphurization plant, has exempted the expense of reconstructing desulfurizing tower; Adopt spray equipment, make full tower resistance less (being generally less than 200Pa); Disposal ability is big, and the institute that enters exhaust tower with tolerancely all can handle; This waste gas purification apparatus most of liquid when operation recycles, and fraction is discharged and carried out the hydrogen sulfide replacement Treatment, has reduced operating cost; When the version of spray equipment adopted atomizer, desulfurized effect was greater than 95%.This device has obvious social, environmental benefit and economic benefit.
