Abstract
The utility model discloses a thin-wall titanium heat exchange pipe. The heat exchange pipe is a pipe body (1) formed by welding a titanium plate, and is characterized in that: the pipe wall thickness of the pipe body (1) is between 0.15 and 0.30 millimeter; the pipe diameter is between 14 and 40 millimeters; and high corrosion resistance and optimal heat exchanging efficiency are achieved. The thin-wall titanium heat exchange pipe is applied to a main heat exchange pipe of a low-temperature multiple-effect seawater desalting evaporator; and by adopting the thin-wall titanium heat exchange pipe, the low-temperature exhaust heat resource is utilized effectively, the performance price ratio and the reliability of a device are enhanced, and the seawater desalting cost is lowered.
Description
Technical field
The utility model relates to a kind of heat transfer tube, and especially a kind of Corrosion Protection is good, heat exchange efficiency is high, can effectively utilize the thin-walled titanium heat transfer tube 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, because existing titanium pipe is limited by working 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 aluminum brass pipe, aluminium-alloy pipe and stainless steel tube etc., 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 thin-walled titanium heat transfer tube of reduction sea water desaltination cost.
Technical solution of the present utility model is: a kind of thin-walled titanium heat transfer 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.
The utility model is to be that the pure titanium plate of 0.15mm～0.30mm is a work material with thickness, welding wire with respective diameters, adopt the method for medium-frequency pulse argon arc welding to be welded, the titanium tube wall thickness of being processed is that 0.15～0.30mm, caliber are 14～40mm, not only have excellent Corrosion Protection, but also have best heat exchange efficiency.Be applied to the main heat transfer tube of low-temperature multiple-effect seawater desalination evaporator, can effectively utilize cryogenic waste heat resource, raising device cost performance and reliability, reduction sea water desaltination cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model embodiment was the same with the procedure of processing of titanium pipe in the past, be about to that the uncoiling of titanium plate, tape splicing storage band location, titanium band clean that corrections, the moulding of titanium band tubulose, argon arc welding parameter are determined, titanium sealing of tube, weld seam protection and cooling, the annealing of tubing sizing, flaw detection aligning calibrate (14～40mm) and coding cutting unload pipe.Different is that the titanium plate thickness is 0.15mm～0.30mm with prior art, and the argon arc welding parameter determines it is that method according to the medium-frequency pulse argon arc welding determines that the diameter of welding wire should be determined according to following formula simultaneously: D=S/2+K, in the formula:
D: be gage of wire mm;
S: be titanium tape thickness mm;
K: be the welding wire correction factor, span is: 0.6≤K≤0.9.
The operational condition of medium-frequency pulse argon arc welding such as following table:
The thickness of pipe of the titanium pipe of being produced is that 0.15～0.30mm, caliber are 14～40mm.
Claims (1)
1. a thin-walled titanium heat transfer 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) is that 0.15～0.30mm, caliber are 14～40mm.
