Description
Technical field
The present invention relates to a kind of exhaust gas processing device, particularly relate to a kind of can the desulfurizing tower of self-skimming.
Background technology
In kiln combustion process, owing to containing sulfide in raw material, make to contain a large amount of gasified harmful substance matter, dust and flue gas in the waste gas after calcining, need by desulfurizing tower, the sulphur in waste gas, dust and flue gas to be removed;
Mainly there are the following problems in running for existing desulfurizing tower: the solid impurity deviate from from waste gas can be deposited on desulfurizing tower inwall, need regularly to clear up desulfurizing tower inwall, remove the gred, the operational efficiency of desulfurizing tower is caused to reduce, and in scale removal process, the anticorrosive coat on desulfurizing tower inwall can be caused to wear and tear, need often to carry out maintenance, improve the operating cost of desulfurizing tower.
Summary of the invention
For the problem in background technology, the present invention proposes a kind of can the desulfurizing tower of self-skimming, comprise housing and be arranged at the liquid storage tank below housing, described housing forms demist section, spray section and air inlet section from top to bottom successively, be provided with demister in demist segment limit, within the scope of spray section, be provided with spray equipment, within the scope of air inlet section, be provided with air inlet, air inlet is communicated with air inlet pipe, and its improvement is:
The housing of air inlet position forms a worm frame distributed along housing circumference, and air inlet pipe is communicated with worm frame, thus the gas that air inlet pipe is exported enters in housing with the tangential direction of housing circumference; Housing below air inlet section forms a funnel shaped liquid storage section, and liquid storage section lower end is provided with blowoff valve; Blowoff valve is communicated with liquid storage tank, is provided with water plug between liquid storage tank and spray equipment; Adsorption liquid circulates between liquid storage tank and desulfurizing tower, and the adsorption liquid liquid level in desulfurizing tower is positioned at the elevation scope of worm frame all the time; When desulfurizing tower runs, blowoff valve is in normally open, adsorption liquid is driven to rotate in a circumferential direction along housing while the gas that air inlet pipe exports contacts with adsorption liquid, impurity in adsorption liquid converges to housing central section under the centripetal force effect rotated, and discharge in liquid storage tank by blowoff valve, effectively avoid Impurity deposition in inner walls.
The principle of aforementioned schemes is: high-temperature tail gas enters in desulfurizing tower by air inlet pipe, and the kinetic energy utilizing tail gas self to contain drives the adsorption liquid in desulfurizing tower to rotate; After tail gas contacts with adsorption liquid, a part of solid granulates in tail gas and flue dust are absorbed by adsorption liquid, a part of sulfur dioxide simultaneously in tail gas also can react with adsorption liquid, reactant is also dissolved in adsorption liquid, follow-up spray equipment and demister again to tail gas be for further processing (spray equipment and the process effect of demister to tail gas same as the prior art, do not repeat them here), the impurity produced after process also can fall to falling in the adsorption liquid in liquid storage section along with water droplet; Because adsorption liquid rotates under the drive of tail gas, solid matter in adsorption liquid can not be deposited on desulfurizing tower inwall, can collect to housing central section under the centripetal force effect rotated on the contrary, the solid matter collecting in middle part is outwards flowed out by blowoff valve along adsorption liquid again, thus make desulfurizing tower possess the function of self-skimming, avoid bits at shell internal deposition, extend the maintenance period interval of desulfurizing tower, improve operational efficiency, reduce operating cost.
In order to improve the absorption efficiency of adsorption liquid to the impurity in tail gas further, the present invention has also done following improvement: described air inlet pipe is tubular structure body, and the inlet end of air inlet pipe is higher than adsorption liquid liquid level, and the outlet side of air inlet pipe is lower than adsorption liquid liquid level.Aforementioned schemes makes tail gas rush at adsorption liquid with downward inclination angle, ensures that adsorption liquid fully contacts with tail gas, meanwhile, also makes the kinetic energy of tail gas more effectively drive adsorption liquid to rotate.
The present invention also proposes following preferred embodiment for liquid storage tank: described liquid storage tank is made up of the first sedimentation basin, reaction tank, the second sedimentation basin and water purifying tank, blowoff valve is communicated with the first sedimentation basin, first sedimentation basin is communicated with by overflow pipe with between reaction tank, be communicated with by filter screen between reaction tank and the second sedimentation basin, be communicated with by overflow pipe between second sedimentation basin and water purifying tank, water purifying tank is communicated with the water inlet end of water plug.The operation principles of liquid storage tank adopts Sodium/Calcium Dual alkali conventional in existing desulfur technology.
The cross section of described air inlet and air inlet pipe can preferably adopt rectangle or circle.
In order to avoid adsorption liquid diffuses out from air inlet pipe, the present invention has also done following improvement, and the housing within the scope of worm frame elevation is provided with overflow mechanism, and overflow mechanism is communicated with liquid storage tank by pipeline.When the liquid level of adsorption liquid exceedes setting height, unnecessary adsorption liquid is back in liquid storage tank by overflow mechanism.
Advantageous Effects of the present invention is: make desulfurizing tower possess self-skimming function, avoid solid impurity to deposit in desulfurizing tower, reduces maintenance times, and reduce operating cost, structure is simple.
