Description
Technical field
The utility model belongs to field of petrochemical industrial, is specifically related to the taper barrel sieve plate in a kind of dry gas desulfurizing tower equipment.
Background technology
Sieve plate, it is one of template with the longest history, industrial application is very extensive, has also been formed a series of good templates through permitting years of researches, as linde sieve tray, MD sieve plate, bubble-cap one sieve tray, netted sieve plate, sieve plate and New Vertical Sieve Tray etc. with baffle plate.
Traditional plate column completes gas-liquid mass transfer and heat transfer with bubbling state mostly, and New Vertical Sieve Tray is to carry out gas-liquid contact under high velocity jet state, the liquid dispersion ejecting from calotte becomes a large amount of droplets, for gas-liquid contact provides very large specific area, mass-transfer efficiency improves greatly.When operation, liquid enters cover body from end gap, gas enters cover body through air rising hole, and its kinetic energy pulls into liquid liquid film and is broken into drop, and two-phase is carried out heat and mass in cover body, then spray from sieve aperture, gas rises, the liquid plate face that falls back, and liquid phase is advanced in process on column plate, repeat said process, finally flow to lower one deck column plate by downspout.Compared with general bubbling plate-type tower, the key of new vertical sieve plate column is that continuous phase has occurred to change mutually with decentralized photo, and gas phase transfers continuous phase to, and liquid phase transfers decentralized photo to, makes the long-pending obviously increase of phase interphase, thus strengthening mass transfer.
The vertical sieve tray of current trend adopts vertical round straight barrel type sieve plate and vertical trapezoidal sieve plate mostly.This type of sieve-plate structure is relatively coarse, wherein vertical trapezoidal sieve plate cylindrical shell is inclined ladder shape, only have two sides to have sieve aperture at trapezoidal cylindrical shell, top calotte is Zhe You turnings, flat deck both sides, relatively low owing to only having two side holes efficiency, in the time that air-flow is flushed to top blind flange from bottom, impact greatly, the dispersive pressure loss of gas phase and liquid phase and flow losses increase, and are not well positioned to meet to a certain extent the requirement of present technique.Be not fine owing to being subject to structure influence gas phase and liquid phase medium mobile performance, the sieve plate inner top pressure loss is larger, has affected to a certain extent mass-transfer efficiency.
Summary of the invention
For the weak point of existing vertical sieve tray technology, the utility model provides the taper barrel sieve plate in a kind of dry gas desulfurizing tower equipment, solve coarse the caused gas phase of existing sieve-plate structure and liquid phase medium mobile performance is bad, the sieve plate inner top pressure loss is larger, affected to a certain extent the problem of mass-transfer efficiency.
Concrete technical scheme of the present utility model is achieved in that
A kind of taper barrel sieve plate, comprises cylindrical shell and cover plate, is welded with cover plate on cylindrical shell, and described cylindrical shell is taper barrel, is provided with sieve aperture on cylindrical shell, and described cover plate bottom center is welded with cone.
Described cover plate is provided with edges of boards, and edges of boards are arc.
Described cylindrical shell mainly plays air-flow guiding function, and the gas phase that bottom is come up and liquid phase are accelerated to rise by cone after mixing; On cylindrical shell, be provided with sieve aperture, mixed gas phase and liquid phase are shed into the abundant haptoreaction of discrete shape; Described cover plate bottom center is welded with cone, and the center line of centrum and the center line of cylindrical shell overlap, and cone plays shunting action, and guiding gas phase and liquid phase shed by the arc edges of boards of cover plate, make more smooth the shedding of gas phase liquid phase, have improved mass-transfer efficiency.
Described cylinder body bottom is evenly provided with 3 imports, and top is evenly provided with 3 outlets, is convenient to like this ejection of gas phase and liquid phase.
When use, taper barrel sieve plate is bolted on tower tray or with tower tray and is welded together, the gas rising from lower floor's column plate like this, meet through plate hole and the liquid entering from cylinder body bottom import, progressively risen by the air-flow that affects of divergent-cone wall, liquid phase is dispersed under high gas flow effect, , and under the guide functions of cone, guiding gas phase and liquid phase are shed by the arc edges of boards of cover plate by the outlet at cylindrical shell top, dispersive pressure loss and the flow losses of gas phase and liquid phase are reduced, so that more smooth sheds, make so again gas phase outside cylindrical shell, fully contact mixing with liquid phase, cone has improved the wall contact area of liquid simultaneously, improve mass-transfer efficiency.
The utility model is simple in structure, convenient and practical, overcome existing sieve-plate structure coarse, the dispersive pressure loss of gas phase and liquid phase and flow losses are increased and affect the shortcoming of mass-transfer efficiency, have advantages of that treating capacity is large, gas phase and liquid phase mixability is high, the pressure loss is little, mass-transfer efficiency is high, be applied in especially in coking plant desulfurizing tower, can reach the effect of high-efficiency desulfurization.
