Such rectangle, waveform etc. are variously-shaped.
In addition, as each heat pipe 40, each heat pipe 50, in addition to using corrugated tube, it is possible to use following adds
Work pipe, this processing pipe is by the tube wall 41 of the smooth pipe smoothing in tube wall 41, tube wall 51, the inner surface of tube wall 51 and outer surface
On be axially integrally provided the projection of multiple ring-types circumferentially extending at a predetermined interval and concavo-convex be processed into.This
Outward, as processing pipe it is also possible to pass through to be integrally provided to projection in the shape of a spiral tube wall 41, the interior table of tube wall 51 of smooth pipe

The such countermeasure of journey.For condenser 4, because using sea water pump 11, the sea water after boosted is supplied to condenser 4,
Therefore, condenser 4 is not readily susceptible to the impact of pressure loss increase, but, for preheater 5, due to condenser 4 row
Cooling sea water out is supplied to preheater 5, and, preheater 5 pressure loss of itself also increases, accordingly, as pre-
The pressure of sea water in the raw material seawater outlet 101 of the outlet of hot device 5 is greatly reduced compared with the situation using smooth pipe.
When pressure loss becomes big, from the sea water supply reduced pressure of raw material seawater outlet 101 when it is possible to cannot be sufficiently to heating
Device 3 base feed sea water.In order to solve these problems although it can be considered that improve sea water pump 11 capacity lift method,
But, in the capacity of the large-scale sea water pump 11 improving further for each sea water in sea water supply to ship being used position
Etc. aspect, there are the operating funds such as cost, amount of power consumption of pump itself and significantly raise such problem.Therefore, in this enforcement
In the vacuum evaporation type desalter 1 of mode, the supply channel 15 between condenser 4 and preheater 5 is arranged small-sized auxiliary
Help pump 9, after the cooling seawater utilization donkey pump 9 that condenser 4 is ejected boosts, supply to preheater 5.Thus, exist
It is also possible to promote the heat exchange between cooling sea water and steam in preheater 5, further, it is possible to the pressure of corresponding cooling sea water
The problem that power loss increases, therefore, it is possible to fully guarantee the output of raw material seawater for heater 3.
Using the vacuum evaporation type desalter 1 of said structure, due to the multibarrel condenser 4 in container body 2
Top arranges multibarrel preheater 5, the raw material seawater of supply to heater 3 is heated, it is therefore not necessary to be used for making preheating
The space that device 5 is provided independently from condenser 4, can seek the miniaturization of device.
And, the inner surface due to each heat pipe 50 to each heat pipe 40 of condenser 4 and preheater 5 and outer surface enter
Go convex-concave processing, therefore, it is possible to improve the heat conductivility of each heat pipe 40, each heat pipe 50.Thus, smooth pipe structure with utilizing
The existing vacuum evaporation type desalter becoming each heat pipe 40, each heat pipe 50 is compared, and can make condenser 4 via preheating
Device 5 and the temperature of raw material seawater that supplies to heater 3 is higher temperature, therefore, it is possible to improve the thermal effect of heater 3 further
Rate.It is additionally, since setting donkey pump 9 on the supply channel 15 between condenser 4 and preheater 5, condenser 4 is ejected
Cooling with seawater utilization donkey pump 9 boosting after, supply to preheater 5, therefore, it is possible to tackle each heat conduction in preheater 5
The cooling sea water of flowing in pipe 50（Raw material seawater）Pressure loss increase problem.Thus, it is possible to heater 3 sufficiently
Base feed sea water.As a result, the manufacture of the fresh water manufacturing in vacuum evaporation type desalter 1 increases, Neng Gouti
The desalting performance of high device.On the other hand, with the existing vacuum steaming constituting each heat pipe 40, each heat pipe 50 using smooth pipe
Hair style desalter is compared, and the desalting performance due to device raises, even if therefore reducing each heat conduction of condenser 4 and preheater 5
Pipe 40, the quantity of each heat pipe 50 are it is also possible to manufacture approximately equal amounts of fresh water.Thus it is also possible to seek the miniaturization of device.
And, in the existing vacuum evaporation type desalter constituting each heat pipe 40, each heat pipe 50 using smooth pipe
In, only smooth pipe is replaced with inner surface and outer surface carried out the corrugated tube of convex-concave processing, processing pipe etc. it becomes possible to improve dress
The desalting performance put, therefore, it is possible to simply and to carry out edition upgrading to existing vacuum evaporation type desalter at low cost.
