Abstract
The present invention relates to passage type indirect heat exchange technology and features that circular tubes for medium heat exchange are arranged in the regular hexagon honeycomb nodes to constitute perfect fluid passage with great heat transferring area. The passage of the present invention can realize complete heat exchange and has obvious energy saving and environment protecting significance, and the said heat exchange structure may be used in manufacturing various heat exchange and heating equipment.
Description
This invention belongs to efficient indirect heat exchange (or heating) technology between two kinds of different temperatures media.As heat exchange between vapour-vapour, vapour-liquid, liquid-liquid, fuel is to indirect of medium etc.
Indirect heat exchange between medium (or heating) technology, be mainly used in the manufacturing heat-exchange apparatus, the version of existing heat-exchange apparatus has: shell-and-tube (as fixed tube sheet type, floating head type, stuffing-box formula and U type tubular type etc.), board-like (as plate-fin, spiral plate type, umbrella is board-like and corrugated plate dst etc.), tubular type (air cooler, bushing type, shower type and case tubular type etc.) and shell-and-plate etc.Detailed content and involved interrelated data index thereof can be consulted " chemical process design manual " etc.
As everyone knows, natural energy source resources such as the human coal that is had, petroleum and natural gas are that finite sum is non-renewable, and these resources will be consumed totally in the near future, and therefore human will have the possibility that faces energy crisis; Moreover these natural energy sources all are the products of savings solar energy, they are just to form in the time in some ten thousand years, and the mankind will focus on the release of these energy in hundreds of years short time, and the greenhouse effects that cause thus (mainly show a large amount of release CO
2, temperature of the earth raises gradually) and will threaten human existence.Therefore, with improving the depletion rate that the approach that has efficiency of energy utilization now reduces natural energy source to greatest extent, develop the new feature of environmental protection energy, the photosynthesis that utilizes the sun is with " excessive " CO
2Be reduced to organic matter, realize the ecological balance of the earth, this is several the very urgent tasks that the human needs does.Purpose of the present invention is exactly that for a change existing hot swapping efficiency of utilization is not high, wastes energy serious present situation and a kind of new and effective power-saving technology that proposes.This technology not only can realize by energy-conservation approach, reaches the purpose of energy savings resource and minimizing pollutant emission, and can be used to collect the new feature of environmental protection energy of solar energy production.Therefore, the present invention has energy-conservation and the environmental protection double meaning, and it is an important component part implementing the energy and environmental protection strategy in person.
The present invention is that a kind of channel-type changes (biography) thermal technology indirectly, and heat exchange interface is the tube wall of circular pipe, and Fig. 1～4 are structure the formation several cross sections example of mode of this kind.Essential characteristic of the present invention is: 1) heat exchanger tube is structured the formation by regular hexagon cellular node position; 2) the heat exchanger tube nominal outside diameter is bordering on or equals the regular hexagon length of side, promptly should be so that face mutually that the heat exchanger tube outer wall is bordering on or just in time tangent being as the criterion (be meant hot tangent down, and might not be tangent under the cold conditions).
The fluid passage of being adopted in this technology, it is a kind of form of perfectly structuring the formation that is close to that I choose from thousands of kinds of combinations, its outstanding feature is: 1) two kinds of more satisfactory fluid passages are arranged: adopt different heat exchange tube diameter and wall thickness, the ratio of tube side and shell side aisle spare can be controlled between 0.50～0.95; 2) increased the heat transfer area in the unit volume and shortened maximum delivered distance between two heat transferring mediums effectively; 3) tangent because of facing two heat exchanger tube outer walls mutually, played the effect of support, so passage length can extend arbitrarily by actual needs under the situation that is not subjected to the restriction of the stressed and support of heat exchanger tube, and pipe thickness can also reduce; 4) tube side and shell side can both adapt to the requirement of high temperature and high pressure; 5) its moulding can be satisfied various requirements of laying the place, and can realize channelization and miniaturization; 6) all realized channelizing because of tube side and shell side, so can realize the complete reverse heat-exchange between truly two media; 7) can realize that channel shape whole process is constant substantially, thereby can reduce the resistance of passage convection cell; 8) wide accommodation can be applicable to that almost two media conducts heat or the various places of heating; 9) processing and fabricating is convenient; 10) can effectively utilize heat energy and minimizing discharging, so this technology has considerable energy saving, reclaims the energy and environment protection significance.In addition, this technology also has fluid passage easy cleaning, energy self-cleaning, is difficult for stopping up, and heat exchanger tube need not add support, and heat exchanger can adapt to the requirement of expanding with heat and contract with cold, and can realize multiple characteristics such as convection cell temperature controlling.
Although there are some versions also can form two kinds of interlaced fluid passages, how all there is such or such defective.For example Fig. 5 and Fig. 6 are to be respectively heat exchanger tube with square and the positive triangle cellular node formed fluid passage of structuring the formation, and it is less by the passage section that the heat exchanger tube outer wall surrounds, and easily stops up; And for example, the fluid passage that Fig. 7～10 are made up of triangle, rectangle, triangle and surface plate, arc-shaped wave card respectively, although their channel shape is comparatively desirable, their less stable, non-refractory high pressure, and processing and fabricating more complicated.
Existing heat-exchange apparatus mostly is positive displacement, and some is multitube journey or multi-segment structure.The heat exchanger tube of these versions, general single tube journey length is generally all shorter, and spacing is also bigger between tube wall, shell side does not have tangible fluid passage again, exist serious short stream and mixed flow phenomenon, thus can not realize reverse heat-exchange truly, thereby the heat exchange effect is relatively poor.
Although plate coil (exchanger) is a channel-type, but its heat exchange efficiency is not high, this mainly is because the defective of its passage itself produces: Figure 11 is the version figure of spiral heat exchanger, as seen from the figure, the passage section of this heat exchanger is actually single rectangle, although its helical duct can infinitely prolong, but the heat exchange area that is had in its unit volume is less (under the situation of same channels width, the heat exchange area that it had only for of the present invention half), this is one of low reason of its heat exchange efficiency; Moreover, although spiral-plate heat exchanger has fluid passage preferably, being same fluid in the both sides of each passage, it exists significantly oppositely heat transfer phenomenon, and this mainly is that equality of temperature is not caused owing to the fluid in same passage both sides.Such as there being two kinds of fluids of high low temperature to carry out reverse heat-exchange by spiral-plate heat exchanger, try that certain section (for example " a ") at high temperature fluid passage locates, if its passage outside with the cryogen heat exchange, cryogen after the heat exchange continues inwardly to flow, and the high temperature fluid heat exchange of continuous and higher temperature, the temperature of cryogen is also in continuous rising at this moment, yet after 360 ° of travelings, cryogen after the intensification has forwarded the inboard that section " a " is located again to, therefore it is low heat exchange efficiency to occur in the inboard of section " a ", not heat exchange, or even the phenomenon of reverse heat exchange, this explanation, real reverse heat-exchange is failed to realize in the fluid passage of spiral-plate heat exchanger, this be the spiral-plate heat exchanger heat exchange efficiency low former therefore two.By contrast, the advantage of the numerous heat transfer technologies of heat exchange technology by means of circular honeycomb tube passage collection is all over the body, and has rejected all drawbacks of existing heat transmission equipment, and the heat exchange structure for a kind of more approaching desirable heat transfer type has unique advantages.
The power saving function of honeycomb pipe hot swapping mainly is the following aspects:
1 usefulness strengthens the heat exchange area in the unit volume, rather than the mode of increasing rate of flow of fluid on the traditional concept or manufacturing fluid turbulence improves the heat exchange effect, therefore can make the flow velocity of two heat exchanging fluids can fall enough lowly, and have evenly constant passage because of whole process, this just makes fluid loss in head in heat transfer process reduce greatly, thereby heat exchange structure itself is exactly a kind of energy-conservation form;
2 can realize the channelization of heat transmission equipment because of this technology, horizontal positioned or another passage technology that adopts me to invent, under some occasion, the maximum position height of heat exchanger is reduced greatly, thereby can reduce the energy that consumes for liquid pressure rise because of overcoming that potential energy draws;
3 because of this technology can really realize complete reverse heat-exchange between two fluids, and heat exchange is abundant, and this has different meanings in different occasions, is several examples below:
(1), can reduce the energy consumption of circulation for recirculated cooling water.Such as in the somewhere, if certain medium will be cooled to 45 ℃ from 90 ℃, under the situation that adopts non-complete reverse heat-exchange, the rational way of less expensive may be to cool off with 32 ℃ recirculated cooling water, and the water temperature after the heat exchange is elevated to 45 ℃.Yet, as use complete reverse heat-exchange mode instead, will produce following two kinds of good effects: a) under the constant situation of quantity of circulating water, can use the recirculated cooling water of higher temperature (for example 37 ℃), the intensification Δ is realized for t=13 ℃.Its meaning is: suppose that it is 28.6 ℃ that wet-bulb temperature is selected in local design for use, then cooling tower cools off back water temperature and the difference that designs wet-bulb temperature, brought up to 8.4 ℃ by original 3.4 ℃, this is to improving the spray density of cooling tower, and the scale and the energy consumption meaning that reduce cooling tower are extremely great; B) if also utilize 32 ℃ water quench, if the water after the heat exchange is warmed up to 55 ℃, the situation that this moment, cooling water inflow can more non-complete reverse heat-exchange reduces more than 40%, and this has not only reduced the energy consumption of cooling tower, and has reduced the energy consumption of recirculated water compression system.
(2) for low-temperature cooling water, sometimes just can circularly cooling: if, if certain medium will be cooled to 23 ℃ from 45 ℃, under the situation that adopts non-complete reverse heat exchange, often need the chilled water cooling with 16 ℃, the temperature difference of cooling water is Δ t=7 ℃ before and after the heat exchange.If adopt complete reverse heat-exchange mode, just may be warmed up to 27 ℃ (or higher temperature) by the underground water of 20 ℃ (or higher temperatures) and realize.For some the area of water at low temperature resource is arranged, just can utilize ready-made water temperature resource, and needn't go power consumption to freeze again, and its water quality of water at low temperature after heating up is constant substantially, is to use for the new water users such as supplementing water of recirculated cooling water, really is to kill two birds with one stone.
(3) for the cold and hot medium heat exchange of chemical process (as be used for fractionating column etc. go out tower height temperature fluid and advance heat exchange between the tower cryogen etc.), if adopt complete reverse heat-exchange mode, can improve the temperature of cryogen after the heat exchange, this just means and has reclaimed more thermal energy, thereby can reduce required fuel or the steam consumption of cryogenic media heating.
4 utilize the waste heat after this technology reclaims the thermo-power station steam turbine generator, can improve the utilization rate of heat energy, and this is significant to the consumption that reduces fuel;
5 these passage technologies are used for boiler, can improve the thermal efficiency of boiler, reduce fuel consumption.
6 utilize this technology and heat transport fluid, can reclaim and utilize heat energy effectively.As reclaim entrained heats such as the solar energy of high-temperature flue gas, high temperature furnace kiln gas, high temperature raw coke oven gas, reception and other high temperature fluids.
This technology can be used for making various heat-exchange apparatus (as the recovery of cooler, condenser, heater, reboiler, evaporimeter, inspissator, waste heat and used heat or utilize some key equipment that equipment, refrigeration plant, fuel boiler, solar energy receives and reclaim etc.).As required, can make by the various moulding of formations such as various heat exchange pipe caliber, various heat exchange thickness of pipe wall, various heat exchange pipe quantity, difformity cross section shell (as circle, rectangle, hexagon, polygon etc.) and unlike material and the heat-exchange apparatus of all size model.The present invention why lay special stress on the mode of structuring the formation of heat exchanger tube and the omnidistance constant or gradual property of fluid passage, be because it has outstanding advantage than multitube journey and multisection type heat exchange mode, but be not to refer to that this technology can not be used for multitube journey and multisection type heat transmission equipment.
