Below in conjunction with the drawings and specific embodiments, heat exchanger of the present invention is described further.
As shown in Figure 1, the multi-functional Latent Heat Storage Exchanger of shell-and-tube, comprise: bobbin carriage 1, housing 2, end socket 3, bilayer sleeve heat exchanger tube 70, tube sheet 6, deflection element 11, tube side fluid passage adapter one, 2 41, 42, shell-side fluid passage adapter one, 2 51, 52, inner tube 71, outer tube 72, metallic support 8 between bilayer sleeve ectonexine pipe, be filled in bilayer sleeve heat exchanger tube, the black box 10 of the phase-changing energy storage material 9 between outer tube and the annular space end of bilayer sleeve heat exchanger tube, this heat exchanger adopts bilayer sleeve heat exchanger tube, between the ectonexine pipe of bilayer sleeve, supporting structure is set, keep ectonexine pipe concentric.Annular space between bilayer sleeve ectonexine pipe fills phase-changing energy storage material, select the sealing of weld metal ring at the two ends of the annular space of bilayer sleeve heat exchanger tube, to be removablely threaded, one or more in removable stuffing box structure seal, ensure that phase-changing energy storage material is not revealed, stop tube side pressurized fluid to enter bilayer sleeve heat exchanger tube annular space, adopt the replacing that latter two sealing means for convenience detach can realize phase-changing energy storage material.
Heat exchanger shell is provided with import as shell-side fluid and discharge connection (i.e. shell-side fluid passage adapter one, 2 51,52), bobbin carriage is provided with import as tube side fluid and discharge connection (i.e. tube side fluid passage adapter one, 2 41,42), all arranges heat-insulation layer outside the housing of the multi-functional Latent Heat Storage Exchanger of shell-and-tube, bobbin carriage and end socket.
The size of the multi-functional Latent Heat Storage Exchanger of above-mentioned shell-and-tube, the transition temperature area of phase-change material, heat storage capacity, store rate of heat release and be applicable to one of the following: the circulating water cooling system, oil field waste residual neat recovering system, solar heat stocking system, Cryo Equipment etc. of building, chemical plant installations.
The use procedure that this heat exchanger is once complete comprises two stages: heat accumulation stage and heat-obtaining stage.During heat accumulation, heat storage fluid flows through from shell side or tube side, by outermost layer wall or the innermost layer wall of bilayer sleeve, heat energy is passed to the phase-changing energy storage material of bilayer sleeve annular space; Phase-changing energy storage material melts, mainly with the thermal energy storage that latent heat form will receive.During heat-obtaining, heat-obtaining fluid flows through from tube side or shell side, by innermost layer wall or the outermost layer wall of bilayer sleeve, is taken away by heat energy from the phase-changing energy storage material of bilayer sleeve annular space; Phase-changing energy storage material solidifies, and is discharged by the heat energy stored before.When heat storage fluid and heat-obtaining fluid are same medium, when can contact with each other, heat storage fluid can walk shell side and tube side simultaneously, from the outermost layer wall of bilayer sleeve and innermost layer wall simultaneously to the phase-changing energy storage material heat supply bilayer sleeve annular space, accelerate charging rate, shorten the heat accumulation time; Heat-obtaining fluid also can walk shell side and tube side simultaneously, from the outermost layer wall of bilayer sleeve and innermost layer wall simultaneously from the phase-changing energy storage material heat-obtaining bilayer sleeve annular space, accelerates heat-obtaining speed, shortens the heat-obtaining time.
Utilize the multi-functional Latent Heat Storage Exchanger of this shell-and-tube to carry out heat accumulation and heat-obtaining, have following three kinds of basic scenarios:
(1) heat storage fluid walks shell side, and heat-obtaining fluid walks tube side;
(2) heat storage fluid walks tube side, and heat-obtaining fluid walks shell side;
(3) heat storage fluid walks tube side and shell side simultaneously, carries out quick heat accumulation, is switched afterwards and makes heat-obtaining fluid walk tube side and shell side simultaneously, carry out quick heat-obtaining by pipeline.
Set forth the operation principle of the multi-functional Latent Heat Storage Exchanger of this shell-and-tube below for the first situation, for other two kinds of situations, operation principle is similar, repeats no more.
During heat accumulation, heat storage fluid (comes from helioplant, the commercial plant of by-product heat energy, need the discharge pipe line etc. of recovery waste heat, heat storage fluid can be liquid, gas or heterogeneous fluid, heat storage fluid temperature is higher than the phase transition temperature of phase-changing energy storage material) enter heat exchanger shell 2 by shell-side fluid passage 51, tube bank and housing common constraint under, sufficiently flow through the outside wall surface of the outer tube 71 of bilayer sleeve, heat is passed to phase-changing energy storage material 9 by the metallic support 8 between the metal level of outer tube 71 and bilayer sleeve ectonexine pipe, energy storage element in phase-changing energy storage material 9 gradually becomes liquid by solid-state, make heat energy constantly be converted into latent heat to store, heat storage fluid self flows out from shell-side fluid passage 52.Through after a period of time, the energy storage element in phase-changing energy storage material 9 is all melted into liquid state, realizes the maximization that latent heat stores, and stops the turnover of heat storage fluid.
During heat-obtaining, heat-obtaining fluid is made (to come from the device needing heat energy, domestic hot-water supply device, mobile heating system etc., heat-obtaining fluid can be liquid, gas or heterogeneous fluid, heat-obtaining fluid temperature (F.T.) is lower than the phase transition temperature of phase-changing energy storage material) enter from tube side fluid passage 41 and 42 and leave heat exchanger, during this period, heat-obtaining fluid passes through metallic support 8 heat-obtaining from phase-changing energy storage material 9 between the inner tube 72 of bilayer sleeve and bilayer sleeve ectonexine pipe, heat-obtaining fluid own temperature constantly raises, and the energy storage element in phase-changing energy storage material 9 solidifies gradually, until after energy storage element all solidifies, latent heat treatment process terminates.Heat accumulation and heat-obtaining process repeatedly can circulate and carry out, until the latent heat storage capacity of phase-changing energy storage material 9 significantly declines, till reaching lifetime.
The multi-functional Latent Heat Storage Exchanger of shell-and-tube of the present invention has that structure is simple, easy to operate, bearing capacity is large, medium and Technological adaptability is strong and phase-change heat-storage material thermal storage density is high advantage, and avoid shortcoming and the drawback of the different phase-change accumulation energy heat-exchanger rigs disclosed in above-mentioned patent, the fields such as solar thermal utilization, middle low-temperature industrial waste heat recovery, mobile heat supply can be widely used in.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
