Embodiment
The utility model illustrates below in conjunction with embodiment:
By accompanying drawing 1 as seen, first kind of embodiment of the present utility model has in the shell 5 of expansion joint 18 thereon, hangs with support and is fixed with the well heater 7 that is made of plate.The position that joins at heating steam inlet pipe 8 and condensating water outlet tube and well heater 7 is respectively equipped with non-condensable gas outlet pipe 4 and 15.The downstream of liquid inlet tube 10 is provided with liquid film divider 9, and will be evaporated the plate outside that liquid is uniformly distributed in well heater by the liquid film divider.Be provided with scum dredger 11 in the upstream of secondary steam outlet pipe 13.Simultaneously also be respectively equipped with expansion joint 16 and 17 on the liquid inlet tube 10 He on the taphole pipe 14.In addition, also be provided with bearing 2 and manhole 3 on the utility model.Be also shown in from figure, heating steam inlet pipe 8 is provided with the additional steam inlet pipe 19 of part steam being introduced the well heater lower end, and to manage 19 inlets that enter in the plate chamber of well heater 7 are 1/3rd to 1/2nd places that are positioned at the plate total height.In addition, in device, be provided with hanging the support 6 that fixed well heater 7 carries out lateral confinement.
The principle of work of present embodiment is: solution to be evaporated is squeezed into solution inlet port 10 by recycle pump, enter on the heat exchange element surface that liquid film divider 9 back is distributed in well heater 7 equably (being on the plate outside surface), and become membranaceous mobile from top to bottom, steam is entered the inner chamber of well heater 7 by steam inlet 8, carry out heat exchange with the liquid film of its outside surface, solution on its outside surface is constantly evaporated, the secondary steam that produces is discharged by secondary steam outlet 13 through scum dredger 11 backs under the depressurized system suction function, is discharged by taphole pipe 14 when concentrated solution concentration reaches set(ting)value.Become water of condensation after the heating steam heat exchange and discharged by condensation-water drain 1, the non-condensable gas that is mixed with in the steam is discharged by non-condensable gas outlet 4/15.Because plate-type evaporator heat exchange of the present utility model meets the film heat-transfer mechanism, enter pipe 19 owing to be provided with supplementary heating steam simultaneously, bottom, plate chamber fully is heated, so its heat transfer efficiency height, evaporation capacity is bigger.
Second kind of embodiment of the present utility model is referring to accompanying drawing 2, its basic structure is identical with first embodiment, but it is directly to introduce from housing that the additional steam in the present embodiment enters pipe 22, in its plate chamber and in the top that additional steam enters pipe 22, be provided with simultaneously not exclusively every road 23, referring to accompanying drawing 3.Additional steam enters the positions of managing 22 settings should be at 1/3rd to 1/2nd places of plate height.As seen from Figure 3 in the plate chamber set not exclusively every road 23 only sealed plate wide about 4/5ths, still leave about 1/5th passage and the chamber conducting of hypomere plate, not exclusively the outlet 25 every road 23 connects end condensed water discharge pipe 21 and epimere non-condensation gas vent pipe 22.From Fig. 3 and Fig. 4, be also shown in and be provided with hemisphere blister convex 24, when forming the plate chamber, the hemisphere blister convex 24 of two plates is arranged relatively, steam is entered produce disturbance behind the plate chamber and breathe heavily stream, the raising heat exchanger effectiveness at each plate.
The basic functional principle of second embodiment is similar to first embodiment, but owing to be provided with not exclusively every road 23 in this example, water of condensation that forms at the inner epimere in when work plate chamber and non-condensable gas come together in not exclusively every the road, and discharge respectively through epimere non-condensation gas vent pipe 21 and the epimere condensed water discharge pipe 22 be located in the outlet 25.Because the water of condensation of epimere is discharged from, replenish the introducing of steam in addition, can make hypomere plate chamber keep higher heat exchange efficiency.
What need special instruction is also the hemispherical protuberances structure should be set on the plate of first embodiment.
