Description

Sub-thread stream reduced pipe wound tube heat exchanger
Technical field
The present invention relates to shell-and-tube heat exchanger technical field, more particularly to a kind of sub-thread stream reduced pipe wound tube heat exchanger.
Background technology
Heat exchanger is the important unit equipment in many industrial productions such as chemical industry, oil refining, power, metallurgy.Around pipe type heat transfer Device is a kind of special shell-and-tube heat exchanger of structure, mainly including housing, core cylinder and around parts such as pipes;Its basic structure be around Pipe is wrapped in core cylinder outside, and core cylinder is located at the central axis of heat exchanger shell pass, is used as the support of winding tube bank.
Relative to other tubular heat exchangers, wound tube heat exchanger is obtained extensively because of its compact conformation, good effect of heat exchange Concern.But in existing wound tube heat exchanger, fluid is spiral flow or has pair in phase transformation, thus pipe in spiral heat exchange tube Flow the coefficient of heat transfer larger;And adjacent ectonexine back cushion bar between pipe is supported in shell side, arrange tighter between layer heat exchanger tube It is close, thus the turbulating effect of shell-side fluid is not enough, convection transfer rate is smaller.Therefore, around shell sides such as the sizes and its arrangement of pipe Structure is the principal element for restricting wound tube heat exchanger complex heat transfer performance.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of sub-thread stream reduced pipe wound tube heat exchanger.
The technical solution adopted by the present invention is:Sub-thread stream reduced pipe wound tube heat exchanger includes bobbin carriage, housing, tube sheet, core Cylinder, path are around pipe, big footpath around pipe, positioning strip, shell side inlet/outlet pipe, tube side inlet/outlet pipe and hanging support, it is characterised in that:Core Cylinder is weldingly fixed on the center of two ends tube sheet, and core cylinder is outer to be wound with path around pipe and big footpath around two kinds of structures of pipe, and it is arranged Mode has two kinds, and the first is that each layer is alternately entwined by path around pipe around Guan Yu great footpaths around pipe, makes the layer and layer around pipe Between mutually supported around pipe by big footpath, big footpath forms larger gap around pipe and path between pipe;Second is close to core cylinder If dried layer winds path around pipe, if path winds big footpath around pipe around the outside dried layer of tube layer;Adjacent ectonexine is around the winding side of pipe Formula is identical with helical angle, but winding direction is on the contrary, adjacent ectonexine is directly contacted between pipe, and the axial direction with layer between pipe Spacing is positioned with positioning strip, and path is respectively separated around two tube heads of pipe around Guan Yu great footpaths and is arranged on the tube sheet of two ends, and with pipe Plate is connected using first swollen rear weldering mode.
The path around pipe, big footpath depending on total heat exchange area of the pipe diameter size according to real exchanger of pipe, path around Pipe may be selected caliber 8 ~ 14mm heat exchanger tube, and big footpath may be selected 12 ~ 19mm of caliber heat exchanger tube around pipe, path around Guan Yu great footpaths around The difference of the caliber of pipe is 4 ~ 6mm.
Compared with prior art, the invention has the advantages that:One is around pipe and big using reducing around pipe i.e. path Footpath replaces canoe around pipe with layer, increases the radial clearance between tube layer, eliminates the filler strip of inside and outside adjacent interlayer, section Save material and made workload, while also solving the problem of same layer is arranged too closely between pipe, enhance shell side stream The flow-disturbing and heat transfer effect of body, and shell-side fluid flow resistance can be reduced;If two be that reducing uses internal dried layer and outside around pipe If the subregion arrangement of dried layer, path around pipe be arranged in close to core cylinder internal layer, can correspondingly reduce core cylinder diameter, fully Shell side space is make use of, adds and winds the number of plies and heat exchange area around pipe, so that heat exchanger overall structure is compacter;Three are Compared to big footpath around pipe, using part path around pipe, tube fluid flow velocity can be improved, so as to heat convection effect and be changed in reinforced pipe Hot device integrates heat transfer effect.

Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
The assembling process of sub-thread stream reduced pipe wound tube heat exchanger:Core cylinder is fixed with two ends Tube-sheet Welding first, core cylinder Positioned at the center of two ends tube sheet, then, for the first around pipe arrangement, first by path around pipe and big footpath around the one of pipe End pipe is adjacent to penetrate same tube sheet, is welded and fixed with pipe clamp with core pipe, and the helical angle according still further to design is alternately wound with layer On core cylinder, two kinds of other end tube heads around pipe are adjacent to penetrate another piece of tube sheet;, first will be small for second around pipe arrangement Footpath penetrates one piece of tube sheet internal layer area around one end tube head of pipe, is welded and fixed with pipe clamp with core pipe, is pressed in the internal layer close to core cylinder If the helical angle according to design first winds dried layer path around pipe, wind big through around pipe again around the outer layer of pipe in path, path around pipe and Big footpath respectively penetrates internal layer and the outer layer region of another piece of tube sheet around the other end tube head of pipe.With axial spacing of the layer between pipe Positioned with positioning strip, positioning strip is weldingly fixed on bottom plate bar in advance, bottom plate bar is axial arranged along core cylinder;Adjacent ectonexine is around pipe Winding direction it is opposite and with identical helical angle, fixed around the two ends of pipe and tube sheet junction using welding mode after first swollen; Core cylinder is integrally loaded into housing around the tube bank that pipe is constituted with reducing, and fixation is respectively welded in two ends tube sheet and housing, by two ends Bobbin carriage is connected by welding with two ends tube sheet.
When sub-thread stream reduced pipe wound tube heat exchanger works, the heat transferring medium of shell side is flowed into from shell-side fluid inlet tube, Path is axially washed away in shell side around Guan Yu great footpaths around pipe, at the same with path around Guan Yu great footpaths around pipe carry out heat convection, finally from Shell side fluid outlet pipe flows out;The heat transferring medium of tube side is flowed into from tube side fluid inlet tube, is distributed by bobbin carriage and is entered small simultaneously Footpath around Guan Yu great footpaths around pipe, heat transferring medium by path around Guan Yu great footpaths around pipe and shell-side fluid heat-shift, finally from tube side Fluid outlet pipe flows out.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
