Abstract
The device belongs to a film type evaporating device. The casing of the evaporating device is provided with a plurality of heat-transfer pipes with the cooperation of lift films. The lift film heat-transfer pipes are mutually connected in series to form a longer flow passage to obtain the larger concentration ratio. The upper passage of each evaporating device can discharge the steam brought by the lift film evaporating heat-transfer pipes, and each passage in the lower part has a common secondary steam discharge port and an injection nozzle enabling the feed solution to rise into the heat-transfer pipes. The evaporating device can be used with single effect, can be connected in series to be used with multiple effects, and can also be combined with an injector to form a heat pump system. The evaporating device is used for evaporating the small-quantity feed solution with the larger concentration ratio, and is suitable for evaporating the heat sensitive materials in the fine chemical industry, the food industry and the pharmaceutical industry.
Description
The invention belongs to kestner long-tube evaporator.
At chemical industry, in the solution concentration of food and pharmaceuticals industry, usually run into that material decomposes, rotten, variable color, problem such as spoiled.For fear of the generation of above-mentioned situation,, also wish solution once by evaporimeter, to shorten the time of staying of feed liquid in device except adopting vacuumizing to reduce the temperature.For evaporation pan, heat-transfer pipe can not be very long, and imitating number can not be a lot, has only increase runner number of passes could once pass through long runner to shorten the time of staying of feed liquid.
Falling film evaporator does not have hydrostatic column loss, and heat transfer temperature difference is little, and dispersed phase holdup is little, is the evaporimeter of desirable concentrated heat sensitive material.But normal general service pump is carried between each journey of existing falling film evaporator, sometimes in same effect, be divided into two journeys, with pump the feed liquid of separation chamber is delivered to intake chamber, as Standiford F.C., Badger W.L is introduced in Eerngy Conservationin Alcohol Production (Chem.Eng.Prog.1983.NO 1.37).For small-sized evaporimeter, many feed pumps of configuration can make equipment investment increase greatly and the multipass falling liquid film is difficult to carry out between each journey.
The objective of the invention is to invent a kind of multipass lift-film evaporator, to solve the solution transportation problem between each journey in the same effect.
Of the present invention being constructed as follows:
Lift-film evaporator of the present invention is array to be housed rise the heat-transfer pipe that film matches with falling liquid film in same housing, and each is organized lifting film heat-transfer pipe and connects mutually, forms long runner, to obtain bigger cocnentration factor.Each organizes upper part of evaporating the passage that connects lifting film heat-transfer pipe, and promptly upper channel rises the steam that the film heat-transfer pipe is produced at this and discharge.There is the passage of the indirect steam of film droping heat-transfer pipe generation lifting film heat-transfer pipe below, and promptly lower channel has the indirect steam outlet on it.Rising film heat-transfer pipe lower end inserts below the liquid level of liquid storage passage (being lower channel).In the porch that rises the film heat-transfer pipe steam nozzle is housed, the high speed steam flow suction feed liquid of coming out from nozzle enters it and rises in the film heat-transfer pipe, rises and heat absorption is evaporated along tube wall because of the shearing force effect of steam and feed liquid makes feed liquid again.What lower channel connected the falling liquid film pipe of last journey and back one journey rises the film pipe, and the feed liquid that promptly last journey falling liquid film pipe flows down enters the below of back one Cheng Sheng film pipe and floods and rises film pipe lower end.Each upper channel is to be separated in same shell, and each lower channel also is that same shell is arranged, and is separated into each runner with the downflow weir of differing heights, makes feed liquid flow to last passage in turn by last passage.The vapor phase of downflow weir top is intercommunicated, and indirect steam gathers the back and discharged by public tube connector.The foam removal baffle plate is equipped with on each upper channel top.
The present invention is the multipass lift-film evaporator, and two to eight journeys can be arranged, and one to quadruple effect.Also but the adapted jet ejector is to constitute the thermo-compression evaporation system, further to save energy.
Accompanying drawing is structure and the schematic flow sheet with two effects, three journey band jet heat pumps.
Material liquid through valve (3), pipeline (4), rise film heat-transfer pipe (5) and enter upper channel (6), solution heat pipe evaporation in pipe, the indirect steam that produces separates in passage (6), enters steam absorbing tube (9) by gland steam exhauster (8) after baffle plate (7) is removed drop.The feed liquid of upper channel (6) enters film droping heat-transfer pipe (10), in pipe, be subjected to thermal evaporation, the indirect steam that produces enters lower channel (11) with feed liquid, steam is discharged through pipe (12), solution is stopped by downflow weir (13) and partly accumulates at lower channel, flood the lower end that rises film heat-transfer pipe (14) of second journey, steam nozzle (15) is housed in the porch of pipe (14).By valve (16), the steam that pipeline (17) comes flows out through nozzle (15), high velocity vapor stream causes decompression on every side, the feed liquid suction is risen in the film heat-transfer pipe (14), feed liquid enters in the upper channel (18) with uperize and the indirect steam that is evaporated, steam through discharge pipe (20), imports in the steam absorbing tube (9) after baffle plate (19) is removed drop.Feed liquid enters in the lower channel (22) through film droping heat-transfer pipe (21), and indirect steam is discharged by pipe (12), and feed liquid is stopped by downflow weir (23) and partly accumulates at lower channel, floods the 3rd Cheng Sheng film heat-transfer pipe (25).The second journey downflow weir apical side height is lower than the first journey downflow weir apical side height, make feed liquid can by journey dirty.Steam is through pipeline (26), nozzle (27) suction feed liquid rises and evaporation, enter upper channel (28) then, steam is through baffle plate (29), discharge pipe (30) and import steam absorbing tube (9), feed liquid is then dirty along falling liquid film pipe (31), enters separation chamber (32), discharge pipe (33), valve (34) and flow to second single-effect evaporator (2).Discharge through pipeline (35) from the indirect steam that pipe (12) is discharged, be divided into two the tunnel, one the tunnel introduces second through pipe (36) imitates (2), another road then enters steam absorbing tube (9) and injector (37), therein by from the suction of the high steam of pipeline (38), mix the back and enter first single-effect evaporator (1) and as the thermal source of this effect along pipe (39).Condensed water is discharged through steam trap (40).
The structure of second single-effect evaporator and flow process are imitated with first, and at lower channel, the indirect steam of each journey falling film evaporation is discharged through pipeline (41).The indirect steam of each climbing film evaporator is collected to pipe (42) through separately upper channel and pipeline.The steam of pipe (41) and pipe (42) is all introduced condenser (43), and condensed water and incoagulable gas all enter distillation tank (44).Coagulate water and discharge through pipe (45), incoagulable gas enters vavuum pump (47) through pipeline (46).Concentrate is by the outlet (48) of second effect the 3rd journey bottom, and valve (49) is discharged.
Advantage of the present invention is as follows:
1, many group (multipass) elevating membrane heat-transfer pipes are in series, and form longer runner, and feed liquid once can obtain bigger cocnentration factor by heat-transfer pipe, is applicable to the evaporation and concentration of heat sensitive material.
2, the feed liquid between each journey is carried without pump and is realized that with nozzle cost of equipment and maintenance cost are low.
3, each Cheng Tongdao is contained in the same housing, facility compact.
4, device height is low.
