Abstract
The utility model discloses a floating head heat exchanger which is composed of a casing, a heat exchange tube bundle, a tube plate, a floating head, an outer connecting tube, a flange bolt connecter, an expanding unit, etc. The floating head heat exchanger is characterized in that an expansion joint can be connected between the casing and the heat exchange tube bundle, which can eliminate the difference of thermal expansion. The floating head is directly connected with the outer connecting tube, which can decrease the flow resistance. The expansion joint and flange connecting pieces are all arranged outside the casing. The utility model has the advantages of convenient installation, compactness and high thermal efficiency. The floating head heat exchanger has simple structure, small flow resistance and convenient maintenance. The floating head heat exchanger is suitable for operating conditions whose heat transfer agents have large temperature differences. The floating head heat exchanger is especially suitable for heat exchangers with high temperature and pressure, such as the heat exchangers in petroleum trade, the heat exchangers in chemical engineering, etc.
Description
The utility model relates to the movable tube sheets heat exchanger technical field.
At the existing heat exchanger that is used for the high temperature fluid medium, generally adopt movable tube sheets heat exchanger, see Fig. 1.1 is the tube side entrance sleeve among the figure, and 2 is the shell side entrance sleeve, and 3 is housing, and 4 is heat-exchanging tube bundle, and 5 is tube sheet, and 6 are floating head, and 7 is the shell side discharge connection, and 8 is the tube side discharge connection.Heat exchanger is in service in work, heat-exchanging tube bundle 4 is because of there being the feeding of high-temperature medium, it is a lot of to expand, and housing itself is lower because of its logical medium temperature of institute, it is less to expand, and the thermal expansion difference between the two is solved by floating head 6, is about to be connected with large-sized flange between floating head and the tube sheet, and it is mobilizable to allow floating head make, and described these floating head connectors all are enclosed in the housing of heat exchanger.Though this floating head structure thermal expansion difference compensates, be totally-enclosed because of raising the nose above water to breathe parts, so install, maintenance is very difficult, therefore only in the occasion of the big temperature difference such as oil refining apparatus, just be used.In addition, this heat exchanger is hot in service in the normal phase, and sealing property is to be difficult to guarantee, so be enclosed in the shell also very difficultly because of seal when changing seal, moreover tube side fluid must turn back as U-shaped raising the nose above water to breathe the position, and flow resistance is also bigger.Oklahoma, United States found the KJBELL of university for this reason, had once proposed to adopt the technical scheme of the floating head parts of expansion joint and multiple flange arrangement in 1980, (see figure 2), and attempt improves movable tube sheets heat exchanger.This scheme is with the thermal expansion difference between heat-exchanging tube bundle 4 and the housing 3, eliminate with expansion joint 9, and expansion joint is to be fixed between tube sheet 5 and the housing 3 by bolt with three cover flanges (10,11 and 12,13 and 13,14), just the large-sized flange syndeton than original is much simple for this, this scheme is also imagined and will be raised the nose above water to breathe directly to communicate with extension tube attached, do not remake the U type and turn back, to reduce the pipe resistance.But because expansion joint and two overlaps being connected still in housing, so problems such as sealing leak, maintenance inconvenience still exist of flanges, bolt in this scheme.
The purpose of this utility model is to improve the structure of floating head connector, makes simple in structure, the good seal performance of new movable tube sheets heat exchanger, and flow resistance is little, the thermal efficiency is high, it is convenient, more economical and practical to install, overhaul.
Structural principle of the present utility model is: with expansion joint and flange, bolt connection piece, the seal between the flange all is arranged on outside the housing, so that install and maintenance; To raise the nose above water to breathe directly to be connected, reduce flow resistance, the thermal efficiency is improved with extension tube attached.
Feature of the present utility model is: an end of floating head 17 links to each other with heat-exchanging tube bundle 4 by tube sheet 5, the other end is both by flange 18,20 and bolt 21 directly communicate with external pipe 23, again by flange 18, inverse flange 19 and bolt 21 and expansion joint 9, flange bolt connector 22 links to each other with housing 3, expansion joint can be eliminated floating head that the heat transferring medium temperature difference causes and the thermal expansion difference between the housing, flange 20 is positioned at the inboard of inverse flange 19, make structure more compact, two screwed holes are arranged on the flange 18, their blind holes for not penetrating, seal 15,16 are assemblied in flange 18 and flange 19, on the joint face of inverse flange 20, so only need to twist bolt and just can stop a leak, so easy to operate in the housing outside.
Fig. 3 is embodiment of the present utility model
Fig. 4 is the partial enlarged drawing of A among Fig. 3
3 is housing among the figure, and 4 is heat-exchanging tube bundle, and 5 is floating tubesheet, and 9 is expansion joint, and 15,16 is seal, and 17 are floating head, and 18 is Floating Head Flange, and 19 is inverse flange, and 20 is the extension tube attached flange, and 21 is bolt, and 22 is the flange bolt connector, and 23 is extension tube attached.Heat-exchanging tube bundle 4 by tube sheet 5 with raise the nose above water to breathe 17 to fuse, floating head is provided with flange 18, and two blind screwed holes are arranged on flange 18, makes by bolt 21, flange 18, external flange 20 and raises the nose above water to breathe 9 directly to communicate with extension tube attached 23, has reduced flow resistance.Raise the nose above water to breathe also to link to each other with housing 3 with flange bolt connector 22 by inverse flange 19, flange 18, bolt 21, expansion joint 9, can eliminate thermal expansion difference between heat-exchanging tube bundle and the shell with this syndeton, expansion joint can be minor diameter.Meanwhile for making compact conformation, flange 20 can be positioned at the inboard of inverse flange, between the joint face of flange 18 and flange 19,20, seal 15,16 should be set, in case the leakage of fluid stopping body, seal can be seals such as metal plain cushion, seal with double-cone, O type ring, flange 18,19,20 materials that adopt, when low pressure, can use steel-casting, use forged steel pieces during middle and high pressure.
Present embodiment is because of structurally making the blue connector of expansion joint and multigroup method all outside housing, removed the large-sized flange connection again, directly draw with raising the nose above water to breathe to take over, so that this heat exchanger becomes the standard type of simple shell-and-tube heat exchanger, and installation and maintenance are all very convenient, are in operation and leak as occurring, and only need twist bolt 21 outside shell and get final product, even overhaul need be changed sealing gasket, demolition also is more convenient.Just because the improvement of above-mentioned these structures makes movable tube sheets heat exchanger not only very suitable for the big situation of the high-temperature medium temperature difference, and because manufacturing expense is low, operating maintenance is convenient, flow resistance is little, and its purposes can enlarge, and it can partly replace U type tubular type and coil exchanger.
