Abstract
The utility model relates to a separated heat pipe with a recirculation pipe. The utility model comprises an evaporation section and a condensing section which is matched with the evaporation section. The evaporation section comprises an upper collecting box, a lower collecting box, an evaporating pipe (5) and a recirculation pipe which are arranged between the upper collecting box and the lower collecting box. The upper collecting box is provided with a subminiature separator which can ensure that the dryness of the steam which goes into the condensation section is 1. The complicated site hot state adjustment can be replaced by the disposable liquid. The utility model can automatically adapt the change of the heat pipe heat exchange loading, especially for the process of the starting and the stoppage. The utility model thoroughly solves the heat pipe safety trouble caused by the heat transferring deterioration of the working solution.
Description
The utility model relates to a kind of heat pipe, particularly a kind of separate heat pipe.
Separate heat pipe is 80 a kind of heat pipe application technologies for new development, it had both had the basic heat exchange property of monoblock type thermal siphon heat pipe, have again big, the hot fed distance of heat exchange power far away, as design of heat exchanger arrangement convenience and other special benefits, (the document: " branch news formula Study of Heat Pipe Heat Exchanger use with estimate " of in large-scale heat exchange of heat pipe, being used widely, Chen Yuanguo, 1988,9 second heat pipe China proceeding P225).But at present domestic and international applied separate heat pipe all adopts the natural circulation mode of circulating ratio K=1, and this has all proposed strict requirement for the steam quality that enters condensation segment and evaporator section working solution to the infiltration degree of the whole pipe range that is heated.If it is bigger to enter the steam moisture of condensation segment, promptly there is liquid to bring into, the condensation segment liquid film is thickeied rapidly, worsen the condensation exothermic process, causing whole piping operating pressure to raise influences the safe operation of heating surface.If it is not enough that the evaporator section working solution soaks into whole pipe range, certainly will cause certain section evaporation tube " dry combustion method ", cause wall temperature to raise and the mechanical strength reduction of material, not only influence the heat exchange efficiency of heat pipe but also the safe operation of entail dangers to equipment.Take place for fear of above-mentioned phenomenon, domestic scholars all is devoted to seek one rational " liquid filled ratio " (being the ratio R that the cold conditions working solution accounts for evaporator section length and whole evaporator section pipe range).And liquid filled ratio R not only has also with the pepeline characteristic of heat transmission equipment, also relevant with the thermic load of heat pipe, a well-known cover separate type heat pipe exchanger all is made up of several groups of independence device roads, every group of loop thermic load is all inequality, this just requires every group of liquid filled ratio all should change, and does not have the operation debugging of coagulating to heat pipe and brings difficulty.In addition, heat pipe is in running, and particularly thermic load is to change in time in the start-up course, and the adjustment of liquid filled ratio at this moment is just more difficult.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, has proposed the irrelevant separate heat pipe of a kind of liquid filled ratio and thermic load, guarantees that entering the condensation segment steam quality is 1, thereby the evaporator section heating surface is had protective effect efficiently.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 be microminiature separator 2 partial enlarged drawing,
Below in conjunction with accompanying drawing the utility model structural principle and operation principle are done detailed explanation.
The utility model comprises an evaporator section 8, and evaporator section 8 is connected with condensation segment 10 by the steam fairlead, and the next part case 9 of condensation segment 10 is connected with the next part case 6 of evaporator section 8 by saturated solution inlet tube 7.Said evaporator section 8 comprise one with the upper collecting chamber of steam fairlead 1 phase configuration, with the next part case 6 of saturated solution inlet tube 7 phase configuration, 6 in upper collecting chamber 3 and next part case dispose evaporation tube 5 and recirculation pipe 4,1 of upper collecting chamber 3 and steam fairlead dispose microminiature separator 2, and said microminiature separator 2 is formed with the tangent guide vane 11 of steam fairlead 1 by one group.
The utility model does not have under the big change condition in existing separate heat pipe structure, and available disposable topping up replaces miscellaneous on-the-spot hot adjustment.The utility model can adapt to the variation of heat pipe heat exchanging load automatically, particularly starts and the stoppage in transit process, has thoroughly solved the heat pipe safety obstacle that the heat transfer deterioration because of working solution causes.
The used blast furnace coal of certain 220T/ high pressure blast furnace coal boiler furnace vapour heater, jeopardize personal safety for preventing that blast furnace gas from leaking to reveal, must adopt separate heat pipe as heat exchange element, 5 every groups 2 of heat exchange power N=15000KW recirculation pipes, diameter phi=65 millimeter, wall thickness=3.5 millimeters totally 22 groups, every steam fairlead is furnished with the microminiature separator, the high h=25 millimeter of its guide vane, 200 millimeters of length L, pitch angle alpha will=45 ° axial symmetry arranges, vane thickness=4 millimeter, the disposable topping up in the whole loops of liquid filled ratio R=45%().
