Description
Technical field
The present invention relates to a kind of heat exchanger tube and production method, especially a kind of Corrosion Protection is good, heat exchange efficiency is high, can effectively utilize the thin-walled titanium heat exchanger tube and the production method of cryogenic waste heat resource, raising device cost performance and reliability, reduction desalinization 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 (bitter) feed liquid is through liquid spraying or liquid distributor, be evenly distributed on the horizontal heat exchange tube bundle in the evaporimeter, 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 heat medium, and steam is freshwater product through the formed condensed water of heat exchange after imitating collection simultaneously.
The heat transfer property of the horizontal heat exchange tube in each single-effect evaporator, corrosion resistance and mechanical strength etc. have tremendous influence to desalination system.Those skilled in the art know that titanium has stronger decay resistance, even still have excellent corrosion resistance in water speed reaches the seawater of 40g/l up to 20m/s or sand content, exceed the existing applied various metal materials of ocean engineering.But, because existing titanium pipe is limited by processing method, its wall thickness is more than the 0.5mm, had a strong impact on heat exchange efficiency, to such an extent as to what the horizontal heat exchange tube in the existing low-temperature multi-effect seawater desalination device generally adopted is aldubra pipe, aluminium-alloy pipe and stainless steel tube etc., decay resistance is relatively poor relatively.
Summary of the invention
The present invention 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 thin-walled titanium heat exchanger tube and the production method of reduction desalinization cost.
Technical solution of the present invention is: a kind of thin-walled titanium heat exchanger tube is the body 1 that is welded with the titanium plate, it is characterized in that: tube wall 2 thickness of described body 1 are that 0.15～0.30mm, caliber are 14～40mm.
A kind of above-mentioned thin-walled titanium heat exchanger tube production method, be to be that 0.15～0.30mm titanium plate is welded with thickness, it is characterized in that: describedly be welded as the medium-frequency pulse argon arc welding; Used gage of wire determines that formula is: D=S/2+K, in the formula:
