Abstract
The utility model relates to a multi-medium tube-and-shell heat exchanger which comprises a heat exchanger shell, at least two tube-pass inlets and tube-pass outlets. A heat medium inlet, a heat medium outlet and a drain outlet are formed in the heat exchanger shell; the tube-pass inlets and the tube-pass outlets are communicated with the heat exchanger shell; heat exchange tubes are connected among the tube-pass inlets and the tube-pass outlets. The multi-medium tube-and-shell heat exchanger is characterized in that at least heat exchange tubes are independently connected with the tube-pass inlet and the tube-pass outlet of each type of media, are spiral tubes and are spirally wound together in the heat exchanger shell. The multi-medium tube-and-shell heat exchanger has the advantages that the multi-medium tube-and-shell heat exchanger has a large heat transfer area in unit volume, is high in heat transfer efficiency and small in occupied area and can be enlarged easily; the multi-medium tube-and-shell heat exchanger is allowed to run at small temperature difference, the pressure drop ratio of a system is low, and accordingly consumption of shell-pass media can be reduced; the multi-medium tube-and-shell heat exchanger can be voluntarily expanded, so that thermal expansion stress can be overcome; heat can be simultaneously transferred by the multiple media, and the like.
Description
Technical field
The utility model belongs to heat exchanger technical field, particularly relates to a kind of multimedium shell-and-tube heat exchanger.
Background technology
Shell-and-tube heat exchanger, is called again tubular heat exchanger, is guaranteeing under the prerequisite that flow is constant, in order to increase heat transfer efficiency, the method of generally taking to increase the quantity of heat exchanger tube pass during design of heat exchanger, to improve the flow velocity of material in heat exchanger, obtains the higher coefficient of heat transfer.Due to reasons in structure, traditional pipe for shell-and-tube exchanger number of passes amount is generally 1～6, shell side is one, this kind of heat exchanger be applicable to same medium heat exchange, and carry out for two kinds or two or more media the heat exchanger said structure that heat changes, be just not suitable for, for the progressive heat exchange efficiency that improves, be provided with a kind of multimedium shell-and-tube heat exchanger
Summary of the invention
The utility model provides the thermal expansion stress of a kind of compact conformation, little, the anti-high pressure of heat transfer temperature difference, tube bank little, can realize the multimedium shell-and-tube heat exchanger that medium conducts heat simultaneously for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A multimedium shell-and-tube heat exchanger, comprises heat exchanger shell, and described heat exchanger shell is provided with heating agent import, heating agent outlet and sewage draining exit; Be communicated with tube side import and the tube side outlet of heat exchanger shell; Tube side import with outlet between be connected heat exchanger tube, it is characterized in that: described tube side import is at least provided with two, the tube side import of each medium and tube side export separate connection mutually heat exchanger tube, the heat exchanger tube of described every kind of medium is helix tube, and at least two above-mentioned heat exchanger tubes are coiled in together at heat exchanger shell inside spin.
The utility model can also adopt following technical characterictic:
The two ends of described heat exchanger tube are provided with free segment.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, have the following advantages: 1, compact conformation, and the heat transfer area that unit volume has is large, and heat transfer efficiency is high, and floor space is little, easily realizes and maximizing.Fluid flows and can form secondary circulation in helix tube, has strengthened heat-transfer effect.2, heat transfer temperature difference is little, and fluid approaches generally respectively counter-current flow in tube side and shell side, and the heat transfer temperature difference that reaches required heat exchange amount needs is less.Permission moves under the less temperature difference, and the Pressure Drop of system is smaller, has reduced the consumption of shell side medium.Therefore in operation maintenance, be, both economical.3, anti-high pressure.Because pipe side heat-transfer pipe is very thin, intensity is high, therefore can pass through high-pressure fluid.4, the thermal expansion stress of tube bank is little.All there is certain free segment at heat exchanger tube two ends, can self-expansions, therefore there is not thermal expansion stress.5, can realize medium conducts heat simultaneously.Several strands of media must heat simultaneously or when cooling, this heat exchanger, due to the particularity of its structure, can be realized the heat exchange of multithread thigh logistics at an easy rate.6, use cryogenic material.Heat exchanger can be made by cryogenic materials such as copper, aluminium, stainless steels, has overcome the black brittleness of the materials such as iron, can adapt to worst cold case.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, heat exchanger shell; 2, heating agent import; 3, heating agent outlet; 4, sewage draining exit; 5, tube side import; 6, tube side outlet; 7, heat exchanger tube; 7-1, free segment.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of multimedium shell-and-tube heat exchanger, comprises heat exchanger shell 1, and described heat exchanger shell is provided with heating agent import 2, heating agent outlet 3 and sewage draining exit 4; Be communicated with tube side import 5 and the tube side outlet 6 of heat exchanger shell 1; Tube side import with outlet between be connected heat exchanger tube 7, described tube side import is at least provided with two, the tube side import of each medium and tube side export separate connection mutually heat exchanger tube, the heat exchanger tube of described every kind of medium is helix tube, and at least two above-mentioned heat exchanger tubes are coiled in together at heat exchanger shell inside spin.
In said structure, in order to overcome swelling stress, at the two ends of described heat exchanger tube, be provided with free segment 7-1.
The heat transfer area that the utility model unit volume has is in sum large, and heat transfer efficiency is high, and floor space is little, easily realizes and maximizing, and allow to move under the less temperature difference, and the Pressure Drop of system is smaller, has reduced the consumption of shell side medium; Can overcome thermal expansion stress by self-expansion simultaneously; Can realize the advantages such as medium conducts heat simultaneously.
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
