Abstract
The invention discloses a kind of sulfur-containing tail gas dedusting and chlorine fluorine removing process device, there is dynamic wave scrubbing gas wash tower, sulphuric acid and fluorine chlorine body knockout tower, alkali liquor and store tower, neutralize absorption tower.Dynamic wave scrubbing gas wash tower has the watery vomiting stream spouting device of bottom, and top has insoluble gas outlet.Acid solution storage tank has leg heater, concentrated sulphuric acid heating release chlorine and fluorine gas.Fluorine chlorine body all connects neutralization absorption tower with washing tower, forms NaCl, NaF.Facility of the present invention is easy, and various compositions carry out separation and recovery in order and utilize, and economize on resources, and substantially accomplish zero-emission.
Description
Technical field
The present invention relates to separation and the purifier of a kind of tail gas.
Background technology
Iron and steel or petrochemical industry, need to carry out substantial amounts of vent gas treatment, in sulfur-containing tail gas, had both had sulfur dioxide, three oxygen
Change sulfur, also have substantial amounts of dust, a small amount of chlorine and fluorine gas.A how economy need in efficient isolation of purified is industry again
The problem persistently to improve.
Number of patent application be 2004100219424 invention propose a kind of dynamic wave scrubber and apply to ammonia-acid process SO2
Tail gas absorption technology.Access the reverse jet tube of dynamic wave scrubber containing SO2 tail gas, flue gas flows from top to bottom, and circulation fluid is by mother solution
Circulating pump sends into reverse jet tube through upper liquid pipe, inversely sprays with airflow direction from shower nozzle is bottom-up, and gas-liquid conversed collision is formed steeps
Foam district, tail gas absorbs after SO2 through mother solution, dynamic wave scrubber outlet gets rid of, and circulation fluid is gone out by from mother solution output bank of tubes.Should
Dynamic wave scrubber function is more single.
Summary of the invention
Goal of the invention:
Thering is provided a kind of dedusting quick, sulfur-containing tail gas dedusting thoroughly and chlorine fluorine removing process device are compared in the removing of chlorine fluorine.
Technical scheme:
The sulfur-containing tail gas dedusting of the present invention and chlorine fluorine removing process device, have dynamic wave scrubbing gas wash tower, sulphuric acid and fluorine chlorine
Body knockout tower, alkali liquor store tower, neutralize absorption tower.
Dynamic wave scrubbing gas wash tower has the smoke inlet of side surface upper part, the watery vomiting stream spouting device of bottom, the acid of bottom
Liquid storage tank, acid solution reservoir bottom has solid waste settling pit (being easy to precipitate and separate solid waste impurity), and top has insoluble gas outlet.
In dynamic wave scrubbing gas wash tower, watery vomiting stream spouting device upwards sprays into current, contrary with flue gas flow direction, flue gas and water
Stream bumps against, it is possible to the dust in the sulfur-containing smoke gas come in by smoke inlet fully absorbs, and forms solid waste and is deposited on solid waste settling pit.
Near flue gas and absorbing liquid momentum balance, major part solubility sulfur trioxide, fluorine gas, chlorine, dust are absorbed by current,
Absorbing liquid turns to, and forms acid solution, and then fall the acid solution storage tank bottom tower body.Microsolubility sulfur dioxide, carbon dioxide and insoluble
Property oxygen, nitrogen etc. pass through current, from top insoluble gas outlet discharge.
Acid solution storage tank passes through acid solution pipeline connection sulphuric acid and fluorine chlorine body knockout tower, and this tower has leg heater, energy
Concentrated sulphuric acid is heated to 60-80 DEG C, and more (almost all) chlorine of concentrated sulphuric acid heating release and fluorine gas, from the fluorine chlorine of tower top
Body outlet is discharged, and discharges without steam for several simultaneously simultaneously；Sulphuric acid flows into and flows out from sulphuric acid outlet at the bottom of tower.
In fluorine chlorine body outlet and absorption tower, washing tower also has in outlet and absorption tower.Fluorine gas, chlorine flow out
After, flowing to neutralize in absorption tower, NaOH or the KOH alkali cleaning flowed out by washing tower absorbs and neutralizes, and forms NaCl, NaF or KCl, KF
Solution, flows out fluoride salt and chlorate side-product from the saline solution outlet of the tower bottom neutralizing absorption tower, substantially accomplishes zero-emission, entirely
Reclaim.And thus realize sulphuric acid and separate with fluorine chlorine body.
Beneficial effect:
The present invention has good dedusting effect, sulfur trioxide and fluorine gas, chlorine absorption thoroughly, and sulfur trioxide and fluorine gas, chlorine
Separation facility easy.Various compositions separate in order, influence each other less, it is thus achieved that recovery material purity all compare
High.The treatment effeciency of whole process unit is high, and construction cost is relatively low, and various useful components can sufficiently be recycled,
Neither atmosphere pollution, economizes on resources again.
