Description
Technical field
The utility model belongs to field of heat exchangers, specifically, relates to a kind of heat exchange tube structure of fixed tube-sheet exchanger.
Background technology
At present, in fixed tube-sheet exchanger there is following defect in heat exchanger tube: in (1) heat exchanger tube, under the low flow condition of medium, turbulent flow is less, be unfavorable for the lifting of heat exchange efficiency, under high flow condition, though can reach higher turbulivity, but the pressure drop that heat exchanger tube bears is large, and energy consumption is high; (2) when the temperature difference of housing and tube wall is larger, for preventing that the damage that thermal (temperature difference) stress brings from need arrange expansion joint; (3) when heat exchanger tube quantity is more, cause its welding capacity more, Leakage probability is large.
Utility model content
For addressing the above problem, the utility model provides that a kind of heat exchange efficiency is high, energy consumption is low, long service life and fixed tube sheet type bourdon tube heat exchanger simple in structure.
Fixed tube sheet type bourdon tube heat exchanger described in the utility model, comprises housing, tube sheet, end socket and heat exchanger tube, and heat exchanger tube is spiral bourdon tube.
Spiral heat exchanger tube substitutes straight tube heat exchanger tube, can increase heat exchange area and heat-exchange time, improves heat exchange efficiency; The quantity of heat exchanger tube is reduced, and welding capacity reduces then, and Leakage probability reduces, and maintenance cost reduces, and extend service life; Heat exchanger tube inner fluid is spinned and is moved along heat exchanger tube, and turbulivity increases, and then can reduce the pressure drop at heat exchanger tube two ends, reduces and leaks, and increases service life.
For better fixing spring pipe, the two ends of bourdon tube are and the integrated straight tube of bourdon tube that straight tube is consistent with bourdon tube axis; The preferred diameter of straight tube is identical with the diameter of bourdon tube.
Preferably, length >=2 of straight tube times tube plate thickness.
Preferably, bourdon tube and straight tube diameter are 25mm, and bourdon tube pitch is 80mm, and screw diameter is 80mm, and tube plate thickness is 50mm.
Compared with prior art, the beneficial effects of the utility model are:
1, heat exchanger tube is spiral tube, has increased contact area and the time of contact of tube side medium and shell side medium, and tube side fluid flow direction is relative with shell-side fluid flow direction staggered simultaneously, and heat exchange efficiency is high, and energy consumption is low;
2, the helical structure of heat exchanger tube, in tube side and the shell side temperature difference when larger, the variable quantity that can offset expands with heat and contract with cold causes, without using expansion joint, simple in structure;
3, the helical structure of heat exchanger tube, can increase heat exchange area, the heat exchanger of same heat exchange area, mounting spring heat exchange tube is compared with installation straight tube heat exchanger tube, and the quantity of required bourdon tube heat exchanger tube is less than straight tube heat exchanger tube, and then can reduce welding capacity, reduce Leakage probability, reduce maintenance cost;
4, when medium flows in tube side, because medium is spinned and moved along bourdon tube in tube side, increase motion change, medium still can keep higher turbulivity in low speed situation, realize the turbulent flow of medium without increase pressure, reduce the pressure drop that heat exchanger tube bears, reduced energy consumption, can extend the service life of heat exchanger tube simultaneously.
