Description

Hot pipe type high-efficiency heat-exchanging system

Technical field

The present invention relates to a kind of hot pipe type high-efficiency heat-exchanging system, is to carry out dynamical heat exchange action by heat pipe, and it is minimum that the heat loss of heating agent is dropped to, and then fills part effect of performance heat exchange, shortens time of heating.

Background technology

Common textile mills, dyeing and finishing factory, Leather Factory, food factory, steel mill or paper mill etc., in the process of producing, all can need a large amount of heat energy, carry out the heating or the boiling-off of dye liquor, just can meet must asking of processing procedure, the process of this heating is all non-usually directly to be heated with fire, but with the heat energy that boiler produces the heated material of above-mentioned desire is heated, promptly be to see through heat-exchange device, give the heated material of desire thermal energy transfer.

The structure of known heat-exchange device such as Fig. 1, shown in 2, be to comprise that two ends respectively are provided with the inlet 11 of heat supply matchmaker turnover and export 12 cylindrical shell 1, and respectively be provided with dividing plate 13 in the both sides of this cylindrical shell 1 inside, make and in cylindrical shell 1, between two dividing plates 13, form a heat exchange space 10 independently, and make these 10 places, heat exchange space be provided with for the inlet 15 of heated substance circulating and to export 16, the majority that has been laid staggeredly between two dividing plates 13 again then props up heat-exchange tubes 14, and allows each heat-exchange tube 14 be communicated with the two ends of cylindrical shells 1.

So the heating agent of high temperature is introduced in the cylindrical shell 1 by inlet 11, make flow through each heat-exchange tube 14 backs and discharge of heating agent by outlet 12, the heated material of desire then is after being introduced by the inlet 15 of 10 belows, heat exchange space in addition, after making it pass through between each heat-

exchange tube

14,16 places are expelled to book office by outlet, so when heated material is flowed through each heat-exchange tube 14, heating agent in this pipe then can be by the conduction of tube wall, and then heated material heated, carry out described heat exchange this moment, so the temperature by the outlet 16 heated materials of being discharged promptly can reach the temperature that must ask, then lower the temperature after the heat exchange because of carrying out by outlet 12 heating agents of being discharged; But, the structure of above-mentioned heat exchange has following problem:

1. because (for example: temperature steam) can be higher in order to make this heating agent; usually can impose pressurization; make the effect of heating better and rapid; so cylindrical shell 1, dividing plate 13 and heat-exchange tube 14 are in order to bear the environment of high pressure for a long time; the thickness of its employed material just must be thicker; simultaneously cylindrical shell 1, dividing plate 13 are relative with the welding quality between each heat-exchange tube 14 has a higher requirement; so the manufacturing cost of this heat-exchange device is not only more expensive, and leak because of the bad of weld often.

2. because in order to allow heat-exchange tube 14 can bear high pressure after the thickened wall, cause the speed of heat energy heat exchange conduction to slow down, and then also allow the usefulness of heat exchange low, so heating agent can't pass to its heat energy under the situation of heated material fully effectively, the time that has produced heat loss and caused heated material to desire to be heated to the temperature of expection also can prolong many, relatively make follow-up production operation be tied down, incur loss through delay, cause the increase of manpower and production cost virtually, and then lose competitiveness.

3. for heated material is heated to predetermined temperature, relatively also can increase the heat time heating time of boiler,,, therefore cause the raising of fuel cost and the waste of the energy just can reach expected effect so also must improve relatively to the energy of boiler heating.

Summary of the invention

The objective of the invention is to disclose a kind of hot pipe type high-efficiency heat-exchanging system,, problem such as installation cost high, energy waste and production capacity reduction not good with the thermal conduction effect that improves prior art.

For achieving the above object, technical solution of the present invention is: make heat-exchange device comprise that an outer cylinder body and an off-centre is located at the inner barrel in the outer cylinder body, reach and on inner barrel, be laid with most root heat pipes, and has dynamical heat conducting heating agent in each heat pipe, and the two ends that make each heat pipe stretch in respectively in the inside and outside cylindrical shell, are provided with fin at the two ends of heat pipe again simultaneously.

In addition, each heat pipe of the invention described above situation is set, can be radial or flat setting shape and be staggered and be laid on the inner barrel.

This practical beneficial effect of the invention is, the technical skill of the dynamical conduction of heat of the heat pipe by the invention described above, add the fin on each heat pipe, more allow the effect of heat exchange more promote, the efficient that makes heat discharge can be brought into play fully, reduce the waste of the heat loss and the energy, so allow the heat energy of heating agent can be fully and promptly discharge and give heated material, and then make the whole heat exchange efficiency of operation of heating agent more improve, so the production capacity of producing can be promoted, human resources can obtain effective utilization, make industry more competitive.

The specific embodiment

Below in conjunction with drawings and Examples this practicality invention is further specified.

Please consult Fig. 3, shown in 4 and 5, the structure of heat-exchange device 2 of the present invention is to comprise that an outer cylinder body 21 and an inner barrel 22 two separate independently space, and make that this inner barrel 22 is that off-centre is located in the outer cylinder body 21, and make this outer cylinder body 21 be provided with and for the inlet 211 of heated material turnover and to export 212, and the two ends of this inner barrel 22 are to stretch out in outside the outer cylinder body 21, but and then form the inlet 221 of heat supply matchmaker turnover and export 222, on the barrel of inner barrel 22, be laid with the heat pipe 23 of most roots then again, and each heat pipe 23 inside is added and is filled the heating agent with high-effect heat conductivity, and the two ends that make each heat pipe 23 are in stretching in respectively, outer cylinder body 22, in 21, and the two ends that make each heat pipe 23 distinctly are provided with again increases the fin 231 of inhaling exothermal efficiency, the situation that is laid on the inner barrel 22 of this each heat pipe 23 is to be the radial setting that is staggered (as each represented hole of inner barrel 22 surfaces of Fig. 3 simultaneously, be the set position of this each heat pipe 23), or the setting that is staggered of parallel setting shape as shown in Figure 6, the heat pipe of respectively organizing parallel setting shape 23 perhaps and for example shown in Figure 7 is the different angles laying that interlaces again.

Therefore, by each heat pipe 23 and inner heating agent thereof, the dynamical heat-conductive characteristic that is produced, add the setting of fin 231, and the area augmentation of heat transfer, the speed of heat transfer are more speeded, and then the effect of heat exchange can be brought into play fully, make and reach dynamical conduction of heat, so that heated material can reach the temperature of expection in the shorter time, and then provide must asking of subsequent production operation, allow production operation smooth and easyly carry out, so make production cost be obtained effective control.

In addition, because the heat exchange effect of heat-exchange device 2 of the present invention is good, so heat loss of the heating agent that can significantly reduce boiler and produced, and then can reduce the waste of the unnecessary energy, but the also cost of fuel saving is simultaneously also because heat pipe 23 is different from the design of known heat-exchange tube pipeline, so the pressure that can bear heating agent and produced, the phenomenon that more difficult generation is leaked between the inside and outside

cylindrical shell

22,21.
