The steam port of device, the 1st effective evaporator connects heat pump, and the heat pump other end is steam inlet, remaining respectively imitates the steam port of evaporator
The steam (vapor) outlet being sequentially connected at the top of an effect separator, each outlet at bottom for imitating separator connect corresponding each effect circulating pump,
The one effect circulating pump can be connected to two effect circulating pumps by valve, and two effect circulating pumps can be connected to triple effect cycle by valve and pump, and three
Effect circulating pump can be connected to concentrated solution outlet by valve, it is characterized in that：It is equipped with preheating between the feed pump and an effect circulating pump
Device, and the steam (vapor) outlet of preheater import connection 1st effective evaporator, preheater outlet can connect with 2nd effect evaporator, triple effect evaporator
Logical, each evaporator top of imitating is equipped with filming device, and the filming device includes cylinder, is distributed part and hollow round table shape on cone
Lower distribution part, cylinder upper end outer rim have the fixture block that may be stuck on evaporation tube, and it is logical to be distributed part both sides on the cone
It crosses connecting plate to connect with cylinder, part upper end opening outer rim is distributed under the hollow round table shape and is equipped with ring baffle, the annular
Baffle upper end both sides are equipped with the supporting rod that part is distributed on connection cone.
Thickness is gradually reduced the wall surface of the cylinder from top to bottom, and the basal diameter of part is distributed under the hollow round table shape
More than the basal diameter for being distributed part on cone.
After adopting the above technical scheme, the setting of preheater makes the steam of 1st effective evaporator discharge obtain secondary use,
For heating original liquid, and extra steam can be transported to 2nd effect evaporator, triple effect evaporator by valve, reduce steaming
The consumption of vapour, in addition, the setting of filming device keeps the cloth film effect of feed liquid more preferable.
Description of the drawings
The utility model has following attached drawing：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of filming device in the utility model.
Specific implementation mode
Shown in referring to Figures 1 and 2, high-efficiency falling film evaporation device provided by the utility model includes sequentially connected by pipeline
Feed pump 1, one imitates circulating pump 2,1st effective evaporator 3, one imitates separator 4, two and imitates circulating pump 5, the effect separation of 2nd effect evaporator 6, two
Device 7, triple effect cycle pump 8, triple effect evaporator 9, triple effect separator 10, the steam port 11 of 1st effective evaporator 3 connect heat pump 12, heat pump
12 other ends are steam inlet 13, and the steam that remaining steam port 11 for respectively imitating evaporator is sequentially connected at the top of an effect separator goes out
Mouth 14, each outlet at bottom for imitating separator connect corresponding each effect circulating pump, and an effect circulating pump 2 can be connected to two effects by valve and follow
Ring pump 5, two effect circulating pumps 5 can be connected to triple effect cycle pump 8 by valve, and triple effect cycle pump 8 can be connected to concentrate by valve and go out
Mouth 15, feed pump 1 and one are equipped with preheater 16, and the steam of 16 import of preheater connection 1st effective evaporator 3 between imitating circulating pump 2
Outlet 17, the outlet of preheater 16 can be connected to 2nd effect evaporator 6, triple effect evaporator 9, and each evaporator top of imitating is equipped with cloth film
Device, filming device include cylinder 18, are distributed part 20,18 upper end outer rim of cylinder under distribution part 19 and hollow round table shape on cone
19 both sides of part are distributed with the fixture block 22 that may be stuck on evaporation tube 21, on cone to connect with cylinder 18 by connecting plate 23,
It is distributed 19 upper end opening outer rim of part under hollow round table shape and is equipped with ring baffle 24,24 upper end both sides of ring baffle are equipped with connection circular cone
The supporting rod 25 of part 19 is distributed in shape, thickness is gradually reduced the wall surface of cylinder 18 from top to bottom, is distributed part under hollow round table shape
20 basal diameter is more than the basal diameter that part 19 is distributed on cone.
In the present embodiment, the setting of preheater 16 makes the steam that 1st effective evaporator 3 is discharged obtain secondary use, is used for
Original liquid is heated, and extra steam can be transported to 2nd effect evaporator 6, triple effect evaporator 9 by valve, reduce steam
Consumption；It is distributed on cone under part 19 and hollow round table shape on distribution part 20, so in addition, feed liquid is fallen successively from top to bottom
The inner wall for flowing to evaporation tube 21 again on the wall surface of cylinder 18 is uniformly fallen afterwards, since the thickness of 18 wall surface of cylinder gradually subtracts
It is small, also just say that the internal diameter of cylinder 18 gradually increases, therefore one can be formed on the inner wall of evaporation tube 21 when downward liquid flow
Layer is uniform to flow thin liquid film, and the indirect steam generated in evaporation process, which passes through, is distributed part 20 and ring baffle under hollow round table shape
24, which form cylindrical channel, rises, and then the gas passage through being distributed on cone between part 19 and supporting rod 25 overflows, and gas is logical
Road space is big, flow velocity and the pressure drop of gas can be reduced, to reduce energy consumption.
