Description
Technical field
The present invention relates to a kind of heat pipe waste-heat recoverer, belong to the technical field of heat-exchanger rig.
Background technology
At present, heat pipe waste-heat recoverer is mainly divided into: monoblock type, separate type and swinging.Wherein, integrated thermal waste-heat recoverer is primarily of compositions such as heat pipe, fixed tube sheet, waste-heat recoverer casing and external insulation materials.Heat pipe relies on the phase transformation of therein hydraulic fluid to realize the heat transfer element conducted heat, and has very high thermal conductivity, excellent isothermal.Parallelly in waste-heat recoverer casing be provided with many heat pipes, fixed tube sheet is provided with in the middle part of heat pipe, fixed tube sheet be provided with multiple can the through hole that passes of heating tube, be used for fixing heat pipe and waste-heat recoverer casing is divided into cold cavity and hot cavity, making cold fluid and hot fluid be located away from fixed tube sheet both sides in casing.Also can sheathed insulation material outside waste-heat recoverer casing, reduce heat and fall apart.Its course of work is as follows: hot fluid (waste heat flue gas) enters waste-heat recoverer casing by one end, expands in the hot cavity side of fixed tube sheet, transfers heat to the hydraulic fluid of inside heat pipe with the heat pipe contact of hot cavity one end.Heat is delivered to the cold cavity of the fixed tube sheet other end by heat pipe, then heat is passed to the cold fluid passing into and circulate in cold cavity, thus realizes heat transfer.
Usually, the projected life of heat pipe waste-heat recoverer is 5-8, but in actual applications, due to the wearing and tearing of the solid particulate matter that corrosivity or the working medium of working medium are mingled with, heat pipe uses 2-3 progressively will occur the phenomenon that leakage, breakage, heat exchange efficiency reduce, and heat pipe is once a large amount of damage will cause the entirety of heat pipe waste-heat recoverer to be scrapped.In addition, because heat pipe waste-heat recoverer is generally non-standard equipment, need whole Transporting, in-site installation, and the volume of equipment own is large, tonnage is high, so transport and installation operation are all comparatively complicated, Expenses Cost is higher.
In order to solve handling problem not easily, Chinese patent literature CN102607321A discloses a kind of heat exchanger and preparation method thereof, in this heat exchanger, heat exchanger tube forms limiting section, and tube sheet is limited in the limiting section of heat exchanger tube.But, this heat exchanger needs two panels tube sheet to close up in opposite directions to coordinate with tube sheet to assemble, must ensure that the Kong Weiyu heat exchanger tube of two panels tube sheet aligns completely like this, require that the position of the limiting section on several heat exchanger tubes is completely the same simultaneously, the matching relationship of guarantee tube sheet and heat exchanger tube, the tube sheet of visible this heat exchanger and the requirement on machining accuracy of heat exchanger tube higher, production cost is higher.
Chinese patent literature CN2198591Y discloses a kind of Split type baffle, and its deflection plate is divided into some laths to assemble.Its installation process is: on heat exchanger tube outer tube wall, weld two locating rings, is suitable for the groove that lath inserts between two locating rings.Many heat exchanger tubes are arranged on 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, singlely can changes, extend the service life of heat exchanger.
But, above-mentioned Split type baffle, also there is following problem: 1) because the locating ring on heat exchanger tube adopts the mode of welding to be fixed on heat exchanger tube, because welding operation itself can not ensure the precision of position, cause the gap length of groove between locating ring to be difficult to manual control, and then loosening or inserting the phenomenon of not entering easily appear in the lath causing thickness to fix when inserting groove; 2) this heat exchanger needs stationary positioned ring on every root heat exchanger tube, and process operation is complicated, and requires machining accuracy equally, the cost of labor of at substantial.
Summary of the invention
For this reason, when technical problem to be solved by this invention is that heat pipe waste-heat recoverer of the prior art manufactures detachable, required precision is high, process is loaded down with trivial details, and then provides that a kind of requirement on machining accuracy is lower, installing/dismounting is simple, heat pipe dismountable compound tube plate-type heat-pipe waste-heat recoverer.
For solving the problems of the technologies described above, compound tube plate-type heat-pipe waste-heat recoverer of the present invention, comprise outer case, several are arranged at the heat pipe as heat transfer element of described outer case inside, for fixing described heat pipe, described outer case is divided into two-part tube sheet, described tube sheet is that several sides have a tube sheet bar being suitable for the arc gap that described heat pipe embeds and are spliced; In described outer case, corresponding described tubesheet location place is provided with locating groove, is suitable for described tube sheet bar and inserts.
Described locating groove is two band steels be arranged in parallel being fixed on described outer case inwall, and the long leg of described tube sheet bar divides shapingly states arc gap to some extent, and the short side part of described tube sheet bar is inserted in the gap of two parallel described band steels.
Described locating groove is symmetrical arranged two on described outer case inwall.
The described arc gap of described tube sheet bar side is semi arch breach.
Sealing ring is provided with between the described arc gap of described heat pipe and described tube sheet bar.
The outer tube wall of described heat pipe is provided with spacing shoulder, and described spacing shoulder is limited on the arc gap of described tube sheet bar.
Described spacing shoulder and described heat pipe are welded to connect.
Described spacing shoulder is the circular pipe clamp be welded on described heat pipe.
