Abstract
The utility model discloses a three-overflow distributor applied to a falling-film evaporator. The three-overflow distributor comprises a tank body, a material tube, a mounting cavity, a pore plate, a distributing plate and a tube plate, wherein the tube plate is provided with a plurality of overflow tubes, arranged in the tank body and used for separating the cavity into an upper chamber and a lower chamber; the mounting cavity is arranged in the upper chamber; the pore plate and the distributing plate are arranged at intervals in turn from top to bottom in the mounting cavity; the material tube is stretched into the mounting cavity from the top of the tank body. By using the three-overflow distributor, the falling-film evaporator is capable of operating efficiently and stably, the operation cycle of the falling-film evaporator is prolonged, the washing frequency is reduced, and the falling-film evaporator can be used efficiently and stably.
Description
Technical field
The utility model relates to a kind of three overflow distributor, relates in particular to a kind of three overflow distributor for falling film evaporator.
Background technology
Evaporimeter is that the solution that the mode by heat exchange will contain the fixedness solute is heated to the boiling situation, makes partial solvent vaporize and be removed, thereby improves the concentration of solute in solvent.
Falling film evaporator in evaporimeter is for the liquid material heating evaporation is concentrated into to required liquid material concentration, and falling film evaporator will have the key of the operational effect of efficient stable to be that whether the distribution of liquid film is rationally even.Existing a lot of falling film evaporator distributes not rationally due to liquid film and is not too even, cause falling film evaporator can't move efficiently when actual motion, heat transfer area can not take full advantage of, also have after the Local Dry wall and produce the phenomenon of tubulation fouling and the equipment cycle of operation is shortened increase cleaning frequency, the efficiency of evaporimeter operation is reduced greatly.
The utility model content
The purpose of this utility model is to solve the problems of the prior art, provides a kind of liquid film to distribute rationally and uniform three overflow distributor for falling film evaporator.
The technical solution of the utility model is: for three overflow distributor of falling film evaporator, comprise tank body, materail tube, installation cavity, orifice plate, distribution plate and tube sheet; Be provided with a plurality of overflow pipes on described tube sheet, described tube sheet is located in tank body and described cavity is isolated into to upper and lower two chambers; Described installation cavity is arranged in upper chamber, from top to bottom spaced orifice plate, distribution plate successively in described installation cavity, and described materail tube stretches to and installs in cavity from the top of tank body.
At the top of described installation cavity, be provided with one with the installing hole of materail tube coupling, described materail tube inserts in this installing hole.
Described orifice plate is arranged at the centre position that cavity is installed, and described distribution plate is arranged at the bottom that cavity is installed.
Be provided with evenly distributed tap hole on described orifice plate, distribution plate.
Tap hole aperture on described orifice plate, flow distribution plate is less than the caliber of described overflow pipe.
Described installation cavity is square or the circular cavity structure.
The utility model can guarantee that liquid material rationally is evenly distributed in the inner surface of vertically moving membrane tubulation after three overflows of orifice plate, distribution plate and tube sheet distribute, because having, the inner surface of all vertically moving membrane tubulations distributes rationally liquid film uniformly, thereby can guarantee taking full advantage of of heat transfer area, can guarantee that the tubulation surface can not produce the phenomenon of dry wall fouling, make the operation that falling film evaporator can efficient stable, extended the cycle of operation of falling film evaporator, reduced cleaning frequency, made the use of falling film evaporator energy efficient stable.
The accompanying drawing explanation
The cutaway view that Fig. 1 is the utility model three overflow distributor.
The specific embodiment
For technological means, technical characterictic, utility model purpose and the technique effect that the utility model is realized is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Be illustrated in figure 1 a kind of three overflow distributor for falling film evaporator of the present utility model, comprise tank body 100, materail tube 101, square installation cavity 200, with the identical orifice plate 300 of installation cavity intracoelomic cavity shape, distribution plate 400 and circular tube sheet 500.Be provided with evenly distributed tap hole on orifice plate 300 and distribution plate 400, for the liquid material overflow is distributed.
The utility model tube sheet 500 is dish-type.Be provided with a plurality of overflow pipes 501 on tube sheet 500, overflow pipe 501, through the plate body of tube sheet 500, can be dispensed to liquid film in the vertically moving membrane tubulation of falling film evaporator along the overflow pipe inwall.Tube sheet 500 circumferentially joins with the inwall 102 of tank body 100, and the cavity of tank body 100 is isolated into to upper chamber 103 and lower chambers 104.Tap hole aperture on orifice plate 300, distribution plate 400 is less than the caliber of overflow pipe 501.
Top arrange the utility model three overflow distributor install on falling film evaporators housing on, materail tube 101 is dispensed to liquid material 600 on orifice plate 300, be that the overflow for the first time that completes that liquid material directly contacts distributes, orifice plate 300 of the present utility model is to determine the porous plate of aperture and hole count after strict calculating.Orifice plate 300 belows have been distribution plates 400 that overflow for the second time distributes, and distribution plate 400 is to determine the porous plate in hole count and aperture after strict calculating.Distribution plate 400 belows have been tube sheets 500 that overflow for the third time distributes, the liquid material 600 that completes the distribution of overflow for the third time on tube sheet 500 can form rationally liquid film uniformly, this liquid film is along the inwall sedimentation of the vertically moving membrane tubulation of falling film evaporator and carry out heat exchange and evaporation and concentration, thereby can guarantee the operation of falling film evaporator stability and high efficiency, fully improve the utilization rate of heat transfer area, reduced the waste of resource and the energy and to the equipment frequent clean and pollution on the environment.
Be only the utility model preferred embodiment in sum, not be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should belong to technology category of the present utility model.
