Background
The heat exchanger is a device for transferring part of heat of hot fluid to cold fluid, and is also called a heat exchanger. The heat exchanger plays an important role in chemical industry, petroleum industry, power industry, food industry and other industrial production, can be used as a heater, a cooler, a condenser, an evaporator, a reboiler and the like in chemical industry production, and is widely applied.
At present, most of tube type heat exchangers are provided with steel tubes which are densely and densely packed, the manufacturing process is very complicated, the welding time of the steel tubes is too wasted, the welding space is narrow, the phenomenon of welding leakage is easily caused, and therefore the equipment is required to be changed.
Heat exchanger equipment adopting heat exchange body and circular ring structure is also available, for example, in "tubular heat exchanger" CN201020026946.2, it includes an outer cylinder, an inner cylinder and a refrigerant tube, the inner cylinder is installed in the outer cylinder and forms an outer circular ring cavity with the outer cylinder, the separation column is arranged in the inner cylinder and forms an inner circular ring cavity with the inner cylinder, the outer cylinder is respectively provided with a water outlet communicated with the outer circular ring cavity and a water inlet communicated with the inner cavity of the inner cylinder, the refrigerant tube is divided into an inner disc curved section and an outer disc curved section which are communicated with each other and respectively and correspondingly arranged in the inner circular ring cavity and the outer circular ring cavity, and the outer ends of the refrigerant tube respectively extend out of the outer cylinder.
The inventor also applies for a heat exchanger device CN201711398733.5 in 2017, which comprises a heat exchange torus, wherein the heat exchange mode of the heat exchange torus adopts a heat exchange medium or a non-heat exchange medium mode, and the inner surface and the outer surface of the heat exchange torus are heat exchange surfaces; when a heat exchange medium is adopted, the heat exchange annular body is provided with an annular interlayer, the heat exchange annular body is provided with a heat exchange annular body inlet and a heat exchange annular body outlet, the heat exchange annular body inlet and the heat exchange annular body outlet are formed in the heat exchanger equipment, and ports of the heat exchange annular body inlet and the heat exchange annular body outlet face outwards. The inlet and the outlet of the heat exchanger are inconvenient to manufacture in actual production, and only two circular rings are convenient to manufacture, one circular ring is convenient to manufacture, and more than two circular rings are difficult to manufacture in actual production, so that the heat exchanger equipment technology is yet to be further developed.
Disclosure of Invention
The object of the present invention is to provide a new heat exchanger device.
One of the technical schemes of the invention is as follows:
a heat exchanger device comprises a tubular heat exchange body and a heat exchange annular body, wherein the heat exchange annular body is arranged in the heat exchange body, the heat exchange body is provided with a heat exchange body inlet and a heat exchange body outlet, the heat exchange annular body is provided with an annular interlayer, the annular interlayer is provided with a heat exchange annular body inlet and a heat exchange annular body outlet for heat exchange medium to enter and exit, and the axial and radial positions of the heat exchange annular body inlet and the heat exchange annular body outlet in the annular interlayer are arranged in a staggered manner; the material channel formed between the heat exchange body inlet and the heat exchange body outlet passes through the outer side and the inner side of the annular replacing interlayer.
Furthermore, the radial positions of the heat exchange ring inlet and the heat exchange ring outlet in the annular interlayer are staggered by 180 degrees, and the axial positions of the heat exchange ring inlet and the heat exchange ring outlet in the annular interlayer are one end or two ends of the annular interlayer.
Furthermore, one or more of a tube type heat exchange device, a coil heat exchange device and a winding type heat exchange device are arranged in the ring of the heat exchange ring body.
The second technical scheme of the invention is as follows:
the heat exchanger device is used as a condenser in a distillation process.
Further, the heat exchanger device is used as a condenser inside the molecular distillation short-path distillation device.
Further, a motor in the short-range distillation equipment is connected with the scraper plate through a connection loose joint, an isolation ring plate is arranged below the heat exchange ring body, the isolation ring plate is used for separating high-boiling point substances and low-boiling point substances in the molecular distillation, and a vacuum port, a heat exchange ring body inlet pipe, a heat exchange ring body outlet pipe, a high-boiling point material outlet and a low-boiling point material outlet are arranged at the bottom end of the molecular distillation equipment;
the material enters the molecular distillation equipment from the material inlet, the connection loose joint is driven under the action of the motor, the scraper is driven through the connection loose joint, the material is forcibly dispersed on the heating wall to be heated under the action of the scraper, vacuum is introduced from the vacuum port, the material with low boiling point is boiled into material steam under the action of the vacuum, the material steam with low boiling point is condensed into liquid again under the action of the heat exchanger, namely a condenser, and the liquid is discharged from the material outlet with low boiling point; under the separation action of the isolating circular ring plate, the high boiling point material without boiling is discharged from the high boiling point material outlet.
The invention has the advantages that the heat exchanger is simple and convenient to manufacture, the processing strength is reduced, the processing cost is lower, but the heat exchange area is larger, the material heat exchange distance is longer, the heat exchange effect is better, and the heat exchanger also has the function of the baffle plates in the original heat exchangers.
Compared with CN201711398733.5, the CN201711398733.5 heat exchanger is very inconvenient when an inlet and an outlet are welded inside a heat exchange ring, especially when a small heat exchanger is manufactured, the design of the inlet and the outlet is more unreasonable, and when a large heat exchanger is manufactured, only two rings (a large ring is sleeved with a small ring) are conveniently manufactured, and then more than two rings are difficult (almost impossible), so that a large space is wasted in the middle. Meanwhile, the CN201020026946.2 tube-tube heat exchanger only needs to be wound by a hose and does not need to be wound by a steel tube, so that the application range is not large, the heat exchange area is not large, and dead angles are not left, and the heat exchange efficiency is not high; CN201711398733.5 except making more than two ring cover rings very inconvenient outside, if the heat transfer heaies up, the pressure of the material pump outside the heat exchanger will be very big, if the condenser in the distillation process, too much ring cover ring, the vacuum pressure drop is too big again, and there are not few dead angles, seriously influence the heat transfer effect, so inner space adds shell and tube, wound heat exchanger, heat transfer area can the increase by times, simultaneously most importantly material in the middle ring is under shell and tube, wound, the torrent effect of coil heat exchange tube, can not form the dead angle, the heat transfer effect is very big improvement.
The heat exchanger has the effect of double-sided heat exchange of the annular heat exchanger and the effect of the baffle plate in the heat exchanger, can be used as a heat exchanger with the same area as a tube type heat exchanger or a wound heat exchanger, and is even larger than the heat exchange area of the tube type heat exchanger or the wound heat exchanger, so that the space in the annular heat exchanger is fully utilized, a larger heat exchange area is manufactured, and a better heat exchange effect is achieved. The invention has been implemented in the molecular distillation apparatus of the applicant's application, producing very good results.
