Abstract
The invention provides a desulfurizing tower with a self-skimming function, which has the improvement that a shell at a gas inlet forms a volute structure capable of being distributed along the circumferential direction of the shell, and a gas inlet pipe is communicated with the volute structure, so that gas output by the gas inlet pipe enters the shell along the direction tangential to the circumferential direction of the shell; the shell below a gas inlet section forms a funnel-shaped liquid storage section, and a blow-down valve is arranged on the lower end of the liquid storage section; the blow-down valve is communicated with a liquid storage pool, and a pumping device is arranged between the liquid storage pool and a sprinkling device; adsorption liquid cyclically flows between the liquid storage pool and a desulfurizing tower, and the liquid level of the adsorption liquid is always in an elevation range of the volute structure; and the gas output by the gas inlet pipe drives the adsorption liquid to rotate along the circumferential direction of the shell while contacting with the adsorption liquid, and impurities are gathered to the middle part of the shell under the action of rotating centripetal force and are discharged by the blow-down valve. The desulfurizing tower has the beneficial effects that the desulfurizing tower has the self-skimming function, solid impurities are prevented from being deposited in the desulfurizing tower, the maintenance times are reduced, the operation cost is reduced, and the structure is simple.
Description
Technical field
The present invention relates to a kind of exhaust gas processing device, but relate in particular to a kind of desulfurizing tower of self-skimming.
Background technology
In the kiln combustion process, owing to contain sulfide in the raw material, contain a large amount of gasified harmful substance matter, dust and flue gas in the waste gas after the feasible calcining, need the sulphur in the waste gas, dust and flue gas be removed by desulfurizing tower;
Mainly there are the following problems in running for existing desulfurizing tower: the solid impurity of deviating from from waste gas can be deposited on the desulfurizing tower inwall, need regularly the desulfurizing tower inwall to be cleared up, removed the gred, cause the operational efficiency of desulfurizing tower to reduce, and in scale removal process, can cause the anticorrosive coat wearing and tearing on the desulfurizing tower inwall, need often carry out maintenance, improve the operating cost of desulfurizing tower.
Summary of the invention
At the problem in the background technology, but the present invention proposes a kind of desulfurizing tower of self-skimming, comprise housing and the liquid storage tank that is arranged at the housing below, described housing forms demist section, spray section and air inlet section from top to bottom successively, be provided with demister in the demist segment limit, be provided with spray equipment in the spray section scope, be provided with air inlet in the air inlet segment limit, air inlet is communicated with air inlet pipe, and its improvement is:
The housing of air inlet position forms one along the circumferential worm frame that distributes of housing, and air inlet pipe is communicated with worm frame, thereby the gas of air inlet pipe output is entered in the housing with the circumferential tangential direction of housing; The housing of air inlet section below 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 the spray equipment; Adsorption liquid circulates between liquid storage tank and desulfurizing tower, and the adsorption liquid liquid level in the desulfurizing tower is positioned at the elevation scope of worm frame all the time; During the desulfurizing tower operation, blowoff valve is in normally open, the gas of air inlet pipe output drives adsorption liquid when contacting with adsorption liquid and rotates in a circumferential direction along housing, impurity in the adsorption liquid converges to the housing middle part under the centripetal force effect of rotation, and discharge to liquid storage tank by blowoff valve, effectively avoid impurity to be deposited on the inner walls.
The principle of aforementioned schemes is: high-temperature tail gas enters in the desulfurizing tower by air inlet pipe, and the kinetic energy that utilizes tail gas self to contain drives the adsorption liquid rotation in the desulfurizing tower; Tail gas is with after adsorption liquid contacts, a part of solid granulates in the tail gas and flue dust are adsorbed liquid and absorb, a part of sulfur dioxide in the tail gas also can react with adsorption liquid simultaneously, reactant also is dissolved in the adsorption liquid, follow-up spray equipment and demister are for further processing to tail gas again, and (spray equipment and demister are same as the prior art to the processing effect of tail gas, do not repeat them here), handling impurity that the back produces also can be along with water droplet falls to falling in the adsorption liquid in the liquid storage section; Because adsorption liquid rotates under the drive of tail gas, solid matter in the adsorption liquid can not be deposited on the desulfurizing tower inwall, can under the centripetal force effect of rotation, compile to the housing middle part on the contrary, the solid matter that collects in the middle part outwards flows out by blowoff valve along adsorption liquid again, thereby make desulfurizing tower possess the function of self-skimming, avoid bits in housing, to deposit, prolong the maintenance period of desulfurizing tower at interval, improve operational efficiency, reduce operating cost.
In order further to improve adsorption liquid to the absorption efficiency of the impurity in the tail gas, the present invention has also done following improvement: described air inlet pipe is the tubular structure body, and the inlet end of air inlet pipe is higher than the adsorption liquid liquid level, and the outlet side of air inlet pipe is lower than the adsorption liquid liquid level.Aforementioned schemes makes tail gas rush at adsorption liquid with downward inclination angle, guarantees that adsorption liquid fully contacts with tail gas, simultaneously, also makes the kinetic energy of tail gas drive the adsorption liquid rotation more effectively.
The present invention has also proposed following preferred embodiment at liquid storage tank: described liquid storage tank is made up of first sedimentation basin, reaction tank, second sedimentation basin and water purifying tank, blowoff valve is communicated with first sedimentation basin, be communicated with by overflow pipe between first sedimentation basin and the reaction tank, be communicated with by filter screen between reaction tank and second sedimentation basin, be communicated with by overflow pipe between second sedimentation basin and the water purifying tank, water purifying tank is communicated with the water inlet end of water plug.The operation principles of liquid storage tank adopts the two alkaline process of Sodium commonly used in the existing desulfur technology.
The cross section of described air inlet and air inlet pipe can preferably adopt rectangle or circle.
Diffuse out from air inlet pipe for fear of adsorption liquid, the present invention has also done following improvement, and the housing in the worm frame elevation scope is provided with overflow mechanism, and overflow mechanism is communicated with liquid storage tank by pipeline.When the liquid level of adsorption liquid surpassed setting height, unnecessary adsorption liquid was back in the liquid storage tank by overflow mechanism.
Useful technique effect of the present invention is: makes desulfurizing tower possess the self-skimming function, avoids solid impurity in desulfurizing tower, to deposit, reduce maintenance times, reduce operating cost, and simple in structure.
