Abstract
The utility model relates to a high efficiency cracking furnace tube, particularly a super conductive heat fin type cracking furnace tube, which comprises a furnace tube body. The furnace tube body is a hollow tube body and a superconductive heat fin is fixedly connected to the furnace tube body. The superconductive heat fin passes through a tube wall of the furnace tube body and one end of the superconductive heat fin is arranged in the furnace tube body, and the other end is arranged outside the furnace tube body. The utility model has the advantages that the superconductive heat fin is made of a small liquid metal heat tube of a superconductive heat element, the inner heat resistance is minimal, the equivalent weight heat conductivity is maximal, and thus the capacity of heat conduction is strong. At the same time, the superconductive heat fin (tube) can pass through the tube wall, which enables heat conduction areas on both sides of the tube wall to be increased simultaneously, and the effect of simultaneously strengthening both sides can be played. Extended surfaces of both sides can be equal and can also be unequal.
Description
The utility model relates to a kind of efficient cracking furnace pipe, is in particular the hot fin cracking furnace pipe of a kind of superconduction.
At present, common fin (fin or nail post) boiler tube is to pass to tube wall by the heat conduction of fin to pass to material again, because the thermal conduction resistance of metal makes the heat transfer efficiency reduction of fin, and generally can not reach two sides and has identical strengthening effect simultaneously.
The purpose of this utility model is exactly to provide a kind of superconduction hot fin cracking furnace pipe for the above-mentioned defective that solves prior art.
The purpose of this utility model can realize by following technical solution:
The hot fin cracking furnace pipe of a kind of superconduction, it includes the boiler tube body, it is characterized in that the boiler tube body is a hollow body, on the boiler tube body, be connected with the hot fin of superconduction, the hot fin of superconduction passes boiler tube body tube wall, and an end of the hot fin of superconduction is located in the boiler tube body, and an end is located at boiler tube, and this is external.
The purpose of this utility model also can further realize by following technical measures:
The hot fin cracking furnace pipe of aforesaid a kind of superconduction, the shape of the hot fin of wherein said superconduction are that tubulose, sheet, tabular, crescent moon, wolf's fang are bar-shaped.
The hot fin cracking furnace pipe of aforesaid a kind of superconduction, the hot fin of wherein said superconduction inside is vacuum, and its inwall has been glued with wick, and working liquid is any in liquid metal sodium, potassium, the mercury.
The hot fin cracking furnace pipe of aforesaid a kind of superconduction, wherein said inner liquid sucting core structure is a wire cloth, or groove, or metal, ceramic powder agglomerating porous medium.
Advantage of the present utility model is that the hot fin of the superconduction of adopting made by the small-sized liquid metal heat pipe of superconduction thermoelectric converter, and its internal thermal resistance is minimum, and equivalent heat conductivity is very big, can exceed plain metal 10
3-10
4Doubly, so its capacity of heat transmission is very big; The hot fin of this superconduction simultaneously can pass tube wall, the heat transfer area of tube wall both sides is increased simultaneously, play the effect that strengthen simultaneously both sides, make the hot fin boiler tube of superconduction can regulate arbitrarily according to the distribution and the heat transfer type in temperature field, the interior outside at the expanding area of boiler tube two sides.The both sides expanding surface can equate, also can not wait.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the structural representation of the hot fin of the utility model superconduction.
Fig. 4 is the utility model in-line arrangement arrangement architecture synoptic diagram.
Fig. 5 is the wrong row of a utility model arrangement architecture synoptic diagram.
As shown in Figure 1 and Figure 2, the utility model comprises that it includes boiler tube body 1, its boiler tube body 1 is a hollow body, on boiler tube body 1, be connected with the hot fin 2 of superconduction, the hot fin 2 of superconduction passes boiler tube body tube wall, one end of the hot fin 2 of superconduction is located in the boiler tube body 1, and an end is located at boiler tube basis external 1.The shape of the hot fin 1 of superconduction is that tubulose, sheet, tabular, crescent moon, wolf's fang are bar-shaped.The hot fin of superconduction 1 inside is vacuum, and its inwall has been glued with wick 6, and superconduct heat media 5 is any in liquid metal sodium, potassium, the mercury.Inner wick 6 structures can be wire cloths, or the groove of different shape, or metal, ceramic powder agglomerating porous medium.4 is to flow through being listed as in the boiler tube to separate fluid.
The utility model is in when work, and the heat of boiler tube outer (or interior) is the pipe outside part of furnace tubing body 1 and the hot fin 2 of superconduction simultaneously.Heat imports in the pipe by the tube wall of boiler tube body 1 on the one hand, and the surface by the hot fin 2 of superconduction directly enters boiler tube inside by fin inside on the other hand.As shown in Figure 3, the hot fin 2 of superconduction is various metallic substance, as stainless steel, high quality steel or various high temperature steel.The inside of the hot fin 2 of this superconduction is the cavity of vacuum but not solid metallic object.Be close in the capillary wick of inwall and be full of liquid metal 5, when hot fin 2 walls of superconduction are in the high temperature fluid, heat 3 in the hot fin 2 absorption high temperature fluids of superconduction arrives the inside of the hot fin 2 of superconduction by hot fin 2 walls of superconduction, be close to the vaporization of being heated of liquid metal 5 in the wick 6 of inner-wall surface, steam flow is reinforced the surface condensation of pipe (device) and emits heat 7, chilled steam becomes saturated liquid, distribution of reflux is to total inner surface under the capillary suction force effect of wick, continue to absorb the extraneous heat that imports into and be vaporizated into steam, circulation so repeatedly reaches the purpose of transmitting heat.The thermal resistance of the hot fin of superconduction 2 inside is very little, and therefore its capacity of heat transmission is also quite big.Can think that the quantity that the utility model is arranged at fin acquires a certain degree, the approach of its heat transmission mainly is by fin rather than the tube wall by boiler tube.Therefore the heat-transfer capability of this boiler tube is twice above than common boiler tube at least.Even can reach 3～5 times.Depend mainly on the actual conditions of cold and hot both sides.As Fig. 4, shown in Figure 5, the hot fin 2 of superconduction of the present utility model can be that in-line arrangement is arranged, and also wrong row arranges.
The utility model because be at common cracking furnace pipe (heating tube) thus going up the additional hot fin of superconduction increases the inside and outside surface-area of boiler tube simultaneously and reaches the raising heat supplied, shorten the residence time of cracking material, the mobile pressure-losses improves the selectivity as cracking materials such as ethene in the minimizing materail tube.This just makes the outer high temperature of cracking furnace pipe import to rapidly in the fluid of cracking furnace pipe inside by the hot fin of superconduction.This is that general fin can't be accomplished.The utility model can be widely used in the various cracking stocks of cracking, as the lighter hydrocarbons of gas plant; The converted products of refinery; Refinery secondary processing wet goods.
