Detailed Description
The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of this application, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit its scope.
Referring to fig. 1 and 2, the present invention provides an on-line heat transfer oil regeneration device. The heat-conducting oil on-line regeneration device can be applied to the regeneration treatment of aged heat-conducting oil.
The heat-conducting oil online regeneration device comprises a distillation device 1, an output main pipe 2, a return main pipe 3, a vacuum pump 4 and a regeneration oil pump 5.
Wherein distillation plant 1 includes distillation chamber 101, heater 102 and condenser pipe 103, and the heater 102 is placed in the distillation chamber 101 in, and condenser pipe 103 intercommunication distillation chamber 101 and vacuum pump 4, output manifold 2 intercommunication conduction oil boiler 100 and distillation chamber 101, and the return manifold 3 intercommunication condenser pipe 103 bottom and conduction oil boiler 100, and regeneration oil pump 5 arranges in the return manifold 3. While the distilled heat transfer oil pitch that has not passed through remains in the distillation chamber 101.
The oil in the heat conducting oil boiler 100 is conveyed into the distillation chamber 101 through the output header pipe 2, is heated by the heater 102, is condensed in the condensation pipe 103 and is collected at the bottom of the condensation pipe 103, and meanwhile, the vacuum pump 4 generates negative pressure in the distillation chamber 101, so that the boiling point of the heat conducting oil is reduced, and the heat conducting oil is easier to gasify. The distilled heat conduction oil is driven by a regeneration oil pump 5 to be conveyed back into the heat conduction oil boiler 100 through a conveying back header pipe 3.
The extraction, distillation and return of the thermal oil in the thermal oil boiler 100 are generally performed simultaneously and continuously. It is preferable to control the thermal oil to be cyclically regenerated two or more times, that is, if there are 40 tons of thermal oil in the thermal oil boiler 100, the total amount of the thermal oil distilled by the distillation apparatus 1 is at least 80 tons, that is, the thermal oil regeneration is considered to be completed.
In this embodiment, the liquid outlet end of the return manifold 3 is higher than the liquid inlet end of the output manifold 2. That is, the output header pipe 2 draws the conduction oil from the bottom of the conduction oil boiler 100, and the return header pipe 3 returns the conduction oil from the top, so that the mixing of new oil and old oil is reduced as much as possible.
In this embodiment, the waste heat transfer oil pump 6 for pumping the waste oil in the heat transfer oil boiler 100 into the distillation chamber 101 is not known in the output header 2. In other embodiments, gravity may be used to allow the used oil to flow into the distillation chamber 101.
In the preferred embodiment the outlet manifold 2 is also provided with a non-return valve 7 to avoid back flow of old oil.
In the embodiment, a cold well 8 is further provided, and the condenser pipe 103 is communicated with the vacuum pump 4 through the cold well 8. The cold well 8 has stronger condensation effect than the condensation pipe 103, and can condense and recover a small amount of residual heat conducting oil steam in the tail gas.
In this embodiment, the bottom of the distillation chamber 101 is further communicated with a residue outlet pipe 9, the other end of the residue outlet pipe 9 is communicated with a residue collection tank 10, and the residue collection tank 10 is used for collecting impurities in the old oil, namely heat transfer oil asphalt. The heat transfer oil asphalt can automatically slide down into the residue collection tank 10 through the residue delivery pipe 9 by using gravity. In other embodiments, a residue discharge pump 11 may be further disposed on the residue discharge pipe 9 to drive the heat transfer oil asphalt to flow into the residue collection tank 10.
In some embodiments, the distillation apparatus 1 employs a molecular still, and molecular distillation is a special liquid-liquid separation technology, which relies on the principle of difference in boiling point difference, but rather on the difference in the mean free path of motion of different substances. When the liquid mixture flows along the heating plate and is heated, light and heavy molecules can escape from the liquid surface and enter the gas phase, because of different free paths of the light and heavy molecules, the molecules of different substances move for different distances after escaping from the liquid surface, if a condensing plate can be properly arranged, the light molecules reach the condensing plate and are condensed and discharged, and the heavy molecules cannot reach the condensing plate and are discharged along the mixed liquid. Thus, the purpose of material separation is achieved. The pressure difference between the boiling film and the condensation surface is the driving force for the steam flow, which is caused by a slight pressure drop.
Basically comprises a cylindrical barrel with a heating jacket, a rotor and an internal condenser; the fixed frame of the rotor is accurately provided with a film scraper and a splash-proof device. The internal condenser is located in the center of the evaporator, and the rotor rotates between the cylindrical drum and the condenser. The short path distiller consists of an externally heated vertical cylinder, a condenser located at its center, and a wiper that rotates between the distiller and the condenser.
The distillation process is as follows: the material is fed from the top of evaporator, and is continuously and uniformly distributed on the heating surface by means of material-liquid distributor on the rotor, then the material-liquid is scraped into a layer of ultrathin turbulent liquid film by means of film-scraping device, and said liquid film is spirally downwards pushed. In the process, light molecules escaping from the heating surface are condensed into liquid on the built-in condenser through a short route and almost without collision, flow down along the condenser pipe and are discharged through a discharge pipe positioned at the bottom of the evaporator; the residual liquid, i.e. the heavy molecules, is collected in a circular channel under the heating zone and then flows out through a discharge pipe on the side.
In other embodiments, the distillation apparatus 1 may also employ a thin film evaporator. The film evaporator features that the material liquid flows in film form along the wall of heating pipe for heat transfer and evaporation, and has the advantages of high heat transfer efficiency, fast evaporation speed and short material residence time, so that it is especially suitable for evaporation of thermosensitive material.
The utility model provides a heat conduction oil on-line regeneration device can directly convey the used oil in a high-temperature state to a distillation chamber through an output header pipe for distillation, thereby avoiding the energy waste of firstly cooling and then heating the used oil in the prior art; meanwhile, the distilled heat conduction oil is guided back into the heat conduction oil boiler through the return main pipe, and oil pumping, distillation and oil feeding are simultaneously carried out through the continuous online processing mode, so that the time for cooling and oven drying is saved, and the time for replacing the heat conduction oil is greatly reduced.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
