The seawater falling film evaporator comprises a shell (1), wherein the upper end of the shell (1) is provided with a seawater inlet (2), a steam outlet (3) and a steam-water separator (4); the steam-water separator (4) is connected with the seawater inlet (2); the lower end of the shell (1) is provided with a strong brine outlet (5); a plurality of horizontal heat exchange pipes (6) which are communicated with the outside of the shell (1) are arranged horizontally in the shell (1); one end of each horizontal heat exchange pipe (6) is arranged in an air inlet header (7), and the other end of each horizontal heat exchange pipe (6) extends into a fresh water tank (8); the air inlet header (7) is provided with an air inlet (9); the fresh water tank (8) is provided with a water outlet (10); and the horizontal heat exchange pipes (6) are titanium pipes of which the wall thickness is between 0.15 and 0.30 millimeter and the pipe diameter is between 14 and 40 millimeters.
Description
Technical field
The utility model relates to a kind of seawater falling-film evaporator, and especially a kind of Corrosion Protection is good, heat exchange efficiency is high, can effectively utilize the titanium tube of thin wall seawater falling-film evaporator of cryogenic waste heat resource, raising device cost performance and reliability, reduction sea water desaltination cost.
Background technology
At present, the horizontal tube falling film evaporation technology has been widely used in the low-temperature multi-effect evaporation desalination device, seawater (brackish water) feed liquid is through liquid spraying or liquid distributor, be evenly distributed on the horizontal heat exchange tube bundle in the vaporizer, under gravity, vacuum induced and air-flow effect, become evenly membranaceous and flow from top to bottom and vapour-liquid is fully separated.The steam that is produced enters down 1st effective evaporator as heating medium, and steam is freshwater product through the formed water of condensation of heat exchange after imitating collection simultaneously.
The heat transfer property of the horizontal heat exchange tube in each single-effect evaporator, erosion resistance and physical strength etc. have tremendous influence to desalination system.Those skilled in the art know that titanium has stronger corrosion resistance nature, even still have excellent solidity to corrosion in water speed reaches the seawater of 40g/l up to 20m/s or sand content, exceed the existing applied various metallic substance of oceanographic engineering.But, if the wall thickness of titanium pipe and caliber do not mate well, will have a strong impact on heat exchange efficiency, be aluminum brass pipe, aluminium-alloy pipe and stainless steel tube etc. to such an extent as to the horizontal heat exchange tube in the existing low-temperature multi-effect seawater desalination device generally adopts, and corrosion resistance nature is relatively poor relatively.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, provide that a kind of Corrosion Protection is good, heat exchange efficiency is high, can effectively utilize cryogenic waste heat resource, improve device cost performance and reliability, the titanium tube of thin wall seawater falling-film evaporator of reduction sea water desaltination cost.
Technical solution of the present utility model is: a kind of titanium tube of thin wall seawater falling-film evaporator, housing is arranged, the upper end of housing is provided with the seawater inlet, vapour outlet and steam separator, steam separator and seawater inlet join, the lower end of housing is provided with the strong brine outlet, horizontal direction is provided with a plurality of horizontal heat exchange tubes that are interlinked to the outside with housing in the described housing, horizontal heat exchange tube one end is inserted in the air inlet bobbin carriage, the other end stretches in the fresh-water tank, on the air inlet bobbin carriage inlet mouth is arranged, water outlet is arranged on the fresh-water tank, and described horizontal heat exchange tube is that wall thickness is 0.15～0.30mm, caliber is the titanium pipe of 14～40mm.
Described housing is made by the titanium plate.
The utility model is simple in structure, not only has excellent Corrosion Protection, but also has best heat exchange efficiency, can effectively utilize cryogenic waste heat resource, raising device cost performance and reliability, reduction sea water desaltination cost.
