Description
Technical field
The utility model belongs to the heat transmission equipment technical field, relates to a kind of heat exchanger that is used for two kinds of fluid at differing temperatures media are carried out the heat exchange of partition periodic disturbance formula.
Background technology
At present there are three kinds of shell-and-tube heat exchanger, plate type heat exchanger and spiral heat exchangers this area at the main heat exchanger of usefulness, and wherein the use with shell-and-tube heat exchanger is the most extensive.Shell-and-tube heat exchanger has container casing and adopts common vessel board making, heat-exchanging tube bundle to adopt welding or expanded joint structure, can bear advantages such as HTHP and operation maintenance convenience, but because exist that heat transfer coefficient is lower, deficiency such as steel consumption is big, external form and floor space are big, it is promoted the use of is subjected to very big obstruction.In addition, because existing shell-and-tube steam water heat exchanger is low to the utilization rate of heating agent (steam), cause the condensate water discharge temperature and compare higher by the temperature value of relevant work pressure and other parameters index Design, so must increase annexes such as steam trap in the condensate water exit, increased safety cost and maintenance cost etc., if further reduce the water temperature of condensing, water-water heat exchanger usually will be installed in series thereafter, so just make system complicated more, floor space is also bigger.The plate type heat exchanger product has also obtained using in recent years morely, its advantage is compact conformation, saving floor space, heat transfer coefficient is bigger when the heat exchange that is used between the liquid, but board-like heat exchanger is with the compacting of expensive metal such as stainless steel, titanium steel, need to be equipped with a large amount of nonmetal rapid wear packing rings in the installation, generally be not suitable for the heat-exchange system of high temperature, gases at high pressure, maintenance cost is higher; In addition, plate type heat exchanger is limit because of its structure, and when being used for vapour-water heat-exchange system, heat transfer efficiency is lower.Spiral heat exchanger is some the shortcoming because of existing on its structure then at present, and use amount is less relatively.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, so a kind of compact conformation be provided, account for that the room floor space is little, load adjustment ability good, high temperature high voltage resistant, easy to operate, less scaling, the thermal efficiency is high and can carry out the efficient return-stroke type heat exchanger that flow process is freely selected according to the operating mode difference.
Technical solution for achieving the above object is such: the efficient return-stroke type heat exchanger that is provided is by the interior cylindrical shell that is provided with heat exchanger tube (double cut spiral) bundle and preceding, rear header constitutes, cylindrical shell is provided with import of shell side medium and outlet, front header is provided with import of tube side medium and outlet, before it is characterized in that, rear header is installed in the two ends of cylindrical shell by tube sheet, have the inside and outside male and fomale(M﹠F) heat-exchanging tube bundle the two ends expanded joint or be welded on the tube sheet, on in cylindrical shell, pressing, the next friendship is every being provided with the vertical deflection plate of polylith, cylindrical shell and before, be respectively equipped with in the rear header shell side dividing plate and before, the rear header pass partition is divided into high district of heating and low district by cylindrical shell shell side dividing plate with cylindrical shell.
Compared with prior art, the utility model has the advantages that:
1, heat transfer efficiency height, load adjustment ability is good: owing to be provided with pass partition and be provided with high low area dividing plate and deflector in forward and backward bobbin carriage in cylindrical shell, heating agent and refrigerant fully contacting have been increased on the heat-exchanging tube bundle surface, reduced the stagnant area, improved heat transfer boundary condition, improved heat exchanger effectiveness, can guarantee that two kinds of heat transferring mediums all can choose suitable flow velocity under the situation of any flow-rate ratio.
2, the high temperature high voltage resistant performance is good, sturdy and durable, easy to maintenance: because heat-exchanging tube bundle and bobbin carriage plate are made by expanded joint or Welding Structure, cylindrical shell adopts flange to be connected with bobbin carriage, does not have easily worn part in the device, dismounting is easy to maintenance, can bear HTHP, sturdy and durable, be easy to safeguard.
3, compact conformation, to account for the room floor space little, can make full use of the space and reduce around operating walk way.
4, during vapour-water heat exchange, the condensate water discharge temperature can be reduced to assigned temperature (the condensate water discharge temperature is higher 3～5 ℃ than secondary heating agent inlet temperature), gas leakage of minimizing system and radiation loss improve the heating agent utilization rate.
5, utilizing heat exchanger tube inside and outside male and fomale(M﹠F) fluid medium to produce strong ripple disturbs, less scaling, conduct heat fully, and can adopt the self-condition of heat exchanger tube to expand with heat and contract with cold, unstressed concentrating solved expanding with heat and contract with cold of traditional product existence in the past and equipment produced the problem of harm.
Description of drawings
Accompanying drawing is the structural representation of a specific embodiment of the utility model.
The specific embodiment
As shown in the figure, efficient return-stroke type heat exchanger described in the utility model is made up of cylindrical shell 1, heat-exchanging tube bundle 2, deflection plate 3, front header dividing plate 4, shell side dividing plate 5, rear header dividing plate 6, front header 8, tube sheet 9, safety valve connecting pipe 12, tie-strut 14 and rear header 15 etc.Forward and backward bobbin carriage 8,15 is installed in the two ends of cylindrical shell 1 by tube sheet 9, (position that this outlet 13 is symmetrical in import 11 is located at the opposite side of cylindrical shell 1 to be provided with shell side medium import 11 and outlet 13 on cylindrical shell 1, not shown), on front header 8, be provided with tube side medium import 10 and outlet 7.Heat-exchanging tube bundle 2 with inside and outside male and fomale(M﹠F) is made by seamless steel pipe, high-quality copper pipe or stainless steel tube and expanded joint or be welded on the tube sheet 9.Hand over every being provided with the vertical deflection plate 3 of polylith by upper and lower in cylindrical shell 1, the quantity of deflection plate 3 is selected according to the needs of runner, lattice.Shell side dividing plate 5 is horizontally installed on the position that is positioned in the cylindrical shell 1 under the heat-exchanging tube bundle 2, and cylindrical shell 1 is divided into high district of heating and low district.Forward and backward bobbin carriage pass partition 4,6 is separately positioned in the forward and backward bobbin carriage 8,15, and dividing plate can be selected according to the difference of medium, temperature and flow.In actual the use, when the tube side medium was steam, heat-exchanging tube bundle 2 should be horizontally disposed; When the tube side medium is liquid, but heat-exchanging tube bundle 2 levels or be arranged vertically.The adapter of each import and export (7,10,11,13) of heat exchanger can make straight tube according to the installation site or 90 ° of elbows are drawn by barrel shell top or front end.Be equipped with the instrument board seat of each unit operational factor (temperature, pressure etc.) or supply the erection support of control automatically at the barrel shell front end.
