Technical scheme
The utility model comprises injector 1, valve 2, water pump 3, pump 4, mist eliminator 5, spray thrower 6, mist eliminator 7, spray thrower 9, housing 11, collecting tank 12 and collecting tank 14, it is characterized in that: utilize dividing plate 8 that several inorganic heat pipes are divided into liquid preheating section tube bank 10, bringing-up section tube bank 13 and liquid evaporator section tube bank 15; Design has some through holes on the described dividing plate 8, and the diameter of through hole equals the diameter of inorganic heat pipe; Described dividing plate 8 carries out encapsulation process with the junction of inorganic heat pipe.
The length of described liquid preheating section tube bank 10, bringing-up section tube bank 13 and liquid evaporator section tube bank 15 is separated ratio, equals the ratio of the heat transfer area of liquid preheating section, bringing-up section and liquid evaporator section.
Number of openings on the described dividing plate 8 is consistent with the quantity of inorganic heat pipe.
The nearly horizontal positioned of described inorganic heat pipe, tube bank angle of inclination are 3～5 degree.The liquid preheating section is restrained 10 ends and is lower than the liquid evaporator section and restrains 15 ends.
Beneficial effect
The utility model adopts the efficient inorganic heat pipe to make heating surface bank, has constituted a kind of spray-type evaporator.Compare with existing spray-type evaporator, advantage is:
(1) heating surface bank of evaporimeter is divided into three sections, i.e. liquid preheating section, bringing-up section and liquid evaporator section.Liquid preheating and evaporation are finished at the two ends of same heating surface bank, liquor preheater need not be set separately, or adopt baroque multiple flow heat exchanger;
(2) the fluid heat transfer process all carries out at the tube bank outer surface, has changed traditional dividing wall type heat transfer type, and it is convenient to make evaporimeter in use restrain replacing, cleaning and scale removal;
(3) because the efficient heat conducting tube axial thermal conductivity is rapid, the intimate isothermal of each point in the tube bank, the overall heat-transfer coefficient height under identical thermic load, reduces about 60% than the heat transfer area of common shell and tube evaporator.
(4) tube bank is divided into three sections, and the pressure in each space, pipeline section place can optionally independent regulation and control, not influence each other.It is comparatively favourable when this makes the present invention be used for low-temperature multi-effect seawater desalination device.
