Abstract
The utility model relates to a liquor-liquor heat exchange process which is suitable for non-pipe outer heat resistance and is used for controlling heat resistance. The traditional turbolator whose length is equal to a heat exchange pipe is divided into a plurality of segments by the utility model, and then, each segment is connected by steel wires to form a segmented turbolator. Due to the fact that liquor passes through secondary circulation and vortex street effect which are generated by each segment turbolator, the flow resistance of the liquor is obviously lowered when the liquor transfers heat inside an intensification pipe, and the integrated performance of a heat exchanger is largely enhanced.
Description
Technical field the utility model is applicable to the liquid-liquid heat transfer process of the tubular heat exchanger in fields such as petrochemical industry, metallurgy, the energy.
Background technology is a kind of efficient ways that improves convective heat-transfer coefficient in the pipe with liquid heat transfer in the insert enhanced tube in the pipe.Insert claims " turbulent accelerator " again in the pipe, and it is used to destroy the boundary layer of the main heat transfer resistance fluid of conduct, the aggravation Hydrodynamic turbulence, and increase the distance that fluid is flowed through in pipe, make the interior convection heat transfer' heat-transfer by convection speed of pipe improve 2 to 8 times.Under the situation of non-pipe external thermal resistance for the control thermal resistance, the also corresponding increase of the overall heat-transfer coefficient of whole heat exchanger.
Liquid-liquid heat exchanger is the most widely used a kind of heat exchangers of industrial circle such as petrochemical industry, the energy, and new technology continues to bring out in recent years.As deflection rod heat exchanger, spiral baffle heat exchanger or the like.But they are only limited to the flow regime that changes shell-side fluid mostly, for the diabatic process of non-pipe external thermal resistance for the control thermal resistance, influence very little.So people come to how attention diversion on the diabatic process in the enhanced tube.Modal is the method that insert is set in pipe, as spiral coil, pipe inner fin etc.But, industrially seldom use because of its processed complex, cost height, heat transfer property are general.
Turbolator (claiming twisted strip or fried dough twist iron again) is the interior insert of a kind of a kind of pipe simple in structure, with low cost, that strengthening effect is good, in gas-gas heat exchange, is used widely, but very little application in liquid-liquid heat exchange.
Why the summary of the invention turbolator is seldom used in liquid-liquid heat transfer process, is that its length is isometric with heat-transfer pipe all the time because when turbolator is strengthened intraductal heat transfer before this.Usually refinery's heat exchanger pipe range is 6 meters, and mostly is 4 tube sides.If be full of twisted strip at tube side, the tube side resistance can significantly increase when then liquid flowed in pipe.The utility model is broken through traditional turbolator and the isometric idea of heat-transfer pipe, adopts the segmentation turbolator to strengthen the method for intraductal heat transfer.So-called " segmentation turbolator " is about to turbolator and is divided into plurality of sections, links to each other with steel wire then.After inserting this kind turbolator in the heat-transfer pipe, when fluid flow through, the secondary circulation that is caused by spiral flow had destroyed the boundary layer of tube fluid, has reduced thermal resistance, has strengthened heat transfer; And the blank space between two sections, because " vortex street " effect that rotatory inertia produced of fluid, strengthening process is still continued, and has reduced flow resistance simultaneously by a relatively large margin.Experimental results show that: to oil-water system, when L/L is compared in Re=2000～10000, segmentation
0When=1, turning round rate Y=6, the corresponding pressure drop of segmentation turbolator convective heat-transfer coefficient has descended 10～15% than whole section turbolator under the same convective heat-transfer coefficient.
This kind turbolator is made by galvanized sheet or aluminium sheet usually: for A type or Type B heat exchanger, the wide e of turbolator sheet is respectively 19mm or 14mm, turbolator thickness δ=0.8～1.0mm, and pitch H=80～120mm turns round rate Y=3～8.
Description of drawings Fig. 1 is a segmentation turbolator schematic diagram.
Specific embodiment segmentation turbolator liquid-liquid heat exchanger is the same with the heat exchanger that other is equipped with insert in the pipe, only limiting to non-pipe is outward the heat transfer process of controlling thermal resistance, that is is to control thermal resistance (as oil-water system) or manage diabatic process interior, pipe external thermal resistance suitable (as oil-oil system) in managing.At first should select the rate of turning round, the segmentation of turbolator parameter such as to compare, make it in augmentation of heat transfer, reduce flow resistance greatly, improve the combination property of liquid-liquid heat exchanger according to the flow regime of tube fluid and rerum natura.Turbolator 2 in the heat-transfer pipe is made up of plurality of sections, and per two is intersegmental continuous by steel wire 1, and establishing each sector boss is L, and per two intersegmental steel wire 1 length are L
0, L/L is compared in segmentation
0=0.5～1.5.In general, work as R
e(entering turbulent region) or tube fluid viscosity was when big (greater than 1.5m Pa.S) when number was big, should adopt bigger rate of turning round (Y＞3) and less segmentation than (L/L
0＜1).
Connect with steel wire 1 between each section of segmentation turbolator 2, the method for available " traction " is inserted in the pipe.Streamwise " is fixed " at pipe end with "+" or "-" shape metal column in the porch, upstream of heat-transfer pipe then.This kind structure makes things convenient for the turnover of turbolator 2, is convenient to clean the maintenance of pipe scale and turbolator 2.
