Description
Technical field
The utility model relates to a kind of heat pipe waste-heat recoverer, belongs to the technical field of heat-exchanger rig.
Background technology
At present, the heat pipe waste-heat recoverer mainly is divided into: monoblock type, separate type and swinging.Wherein, the integrated thermal waste-heat recoverer mainly is made up of heat pipe, fixed tube sheet, waste-heat recoverer casing and external insulation material etc.Heat pipe is to rely on self internal work liquid phase-change to realize the heat transfer element that conducts heat, and has very high thermal conductivity, good isothermal.Parallelly in the waste-heat recoverer casing be provided with many heat pipes, the heat pipe middle part is provided with fixed tube sheet, but fixed tube sheet is provided with the through hole that a plurality of heating tubes pass, be used for fixing heat pipe and the waste-heat recoverer casing is divided into cold cavity and hot cavity, make cold fluid and hot fluid be located away from the interior fixed tube sheet both sides of casing.The waste-heat recoverer casing outside also can sheathed insulation material, reduces heat and looses.Its course of work is as follows: hot fluid (waste heat flue gas) enters the waste-heat recoverer casing by an end, expands hot cavity one side in fixed tube sheet, contacts with the heat pipe of hot cavity one end and with the hydraulic fluid of heat transferred inside heat pipe.Heat pipe is delivered to the cold cavity of the fixed tube sheet other end with heat, again heat transferred is fed the cold fluid that circulates in the cold cavity, thereby realizes conducting heat.
Usually, be 5-8 the projected life of heat pipe waste-heat recoverer, but in actual applications, because the corrosivity of working medium or the wearing and tearing of the solid particulate matter that working medium is mingled with, heat pipe uses that leaking will progressively appear in 2-3, damaged, phenomenon that heat exchange efficiency reduces, and heat pipe is in case a large amount of damages will cause the integral body of heat pipe waste-heat recoverer to be scrapped.In addition, because the heat pipe waste-heat recoverer is generally non-standard equipment, need whole Transporting, the on-the-spot installation, and the volume of equipment own is big, tonnage is high, thus transportation and fitting operation all comparatively complicated, to expend cost higher.
In order to solve loading and unloading problem easily inadequately, Chinese patent literature CN102607321A discloses a kind of heat exchanger and preparation method thereof, in this heat exchanger, forms limiting section on the heat exchanger tube, and tube sheet is limited in the limiting section of heat exchanger tube.But, this heat exchanger needs two tube sheets to close up in opposite directions to fit into luggage with tube sheet to join, the Kong Weiyu heat exchanger tube that must guarantee two tube sheets like this aligns fully, require the position of the limiting section on several heat exchanger tubes in full accord simultaneously, could guarantee the matching relationship of tube sheet and heat exchanger tube, as seen the requirement on machining accuracy of the tube sheet of this heat exchanger and heat exchanger tube is higher, and production cost is higher.
Chinese patent literature CN2198591Y discloses a kind of split type deflection plate, and its deflection plate is divided into some laths and assembles.Its installation process is: at two locating rings of heat exchanger tube outer tube wall welding, be suitable for the groove that lath inserts between two locating rings.Many heat exchanger tubes are installed on the lath in a manner described, and some laths form complete deflection plate through assembling again.Above-mentioned deflection plate is demountable structure, and heat exchanger tube can singlely be extracted out; When heat exchanger tube is damaged, can singlely change, prolonged the service life of heat exchanger.
But, above-mentioned split type deflection plate, also there is following problem: 1) because the locating ring on the heat exchanger tube adopts the mode of welding to be fixed on the heat exchanger tube, because welding operation itself can not guarantee the precision of position, cause that the gap length of groove is difficult to artificial control between the locating ring, and then cause the lath of fixed thickness when inserting groove, to be prone to loosening or insert the phenomenon of not entering; 2) this heat exchanger need be on every heat exchanger tube the stationary positioned ring, process operation complexity, and require machining accuracy equally expends a large amount of costs of labor.
