Abstract

The invention discloses a rectangular fully welded U-shaped tube type heating network heater, which belongs to heat transfer equipment, particularly to steam-water heat transfer equipment using U-shaped heat transfer tubes. The rectangular fully welded U-shaped tube type heating network heater comprises a heat transfer tube bundle formed by the U-shaped heat transfer tubes and mounted in a casing, and a tube box provided with a secondary heat medium inlet and a secondary heat medium outlet and mounted at one end of the casing, wherein the heat transfer tube bundle is formed by a rectangular tube plate, the U-shaped heat transfer tubes and rectangular support plates; the U-shaped heat transfer tubes sequentially penetrate at least two rectangular support plates and the rectangular tube plate and are in welding connection and expanded joint with the two types of plates; a semi-circular steam ingoing collection box with a steam inlet is welded above parallel side plates A and B of the casing, and a semi-circular water outgoing collection box with an outgoing water outlet is welded below the side plates A and B; the semicircular cylinder-shaped tube box with the secondary heat medium inlet and the secondary heat medium outlet is welded to the end of the casing, at which the rectangular tube plate is welded. Compared with the conventional U-shaped tube type heat transfer equipment, the fully welded structure is more reliable in sealing, stronger in temperature resistance and pressure resistance, and simpler in structure.

Description

Rectangle welds U-shaped tubular type heat exchangers for district heating entirely
Technical field
The invention belongs to heat transmission equipment, particularly use the steam-water heat exchanging equipment of U-shaped heat exchanger tube.
Background technology
Traditional U-shaped tubular type heat exchangers for district heating, version is: circular shell and circular tube sheet, heat exchanger tube are the U-shaped pipe, two ports of heat exchanger tube at one end are connected with tube sheet, toroidal shell side neck body and circular Tube-sheet Welding.Its great advantage is the thermal (temperature difference) stress that does not have the shell side.Its shortcoming is that housing steam free air space is little, can not carry out replace tubes and defect repair difficulty, and heat exchanger tube stops up and is not easy to dredging etc.Traditional U-shaped pipe heat exchangers for district heating is in operation and tube bank occurs leaks the situation such as disconnected pipe and often occur, and this has just affected normal heat supply.So urgently in the industry wish a kind of heat exchangers for district heating and can satisfy long-term safety operation under each operating condition.Those skilled in the art also urgent hope develops a kind of U-shaped pipe heat exchangers for district heating, solves its inherent defective.But up to the present new progress is not arranged yet.
Summary of the invention
In order to overcome the deficiency of existing U-shaped tubular type heat exchangers for district heating, the purpose of this invention is to provide a kind of rectangle and entirely weld U-shaped tubular type heat exchangers for district heating.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rectangle welds U-shaped tubular type heat exchangers for district heating entirely, the heat-exchanging tube bundle, housing one end that comprise the U-shaped heat exchanger tube composition that is installed in the housing are equipped with the bobbin carriage of importing and exporting with the secondary heating agent, it is characterized in that: described heat-exchanging tube bundle is comprised of rectangle tube sheet, U-shaped heat exchanger tube, rectangle support plate, and the U-shaped heat exchanger tube passes at least 2 rectangle support plates and passes the rectangle tube sheet again and add expanded joint with its welding and be connected; The side plate A side plate B that the is parallel to each other top of described housing is welded with the semicircle admission header with steam inlet, the below is welded with semicylindrical hydrophobic header with hydrophobic outlet, and an end that is welding the rectangle tube sheet is welding semicylindrical bobbin carriage with the import and export of secondary heating agent.
The right and left of described rectangle support plate is welded to connect with side plate A, side plate B respectively; The right and left of rectangle tube sheet is welded to connect with the end of side plate A, side plate B respectively; The end, 4 limit of bobbin carriage is welded to connect with 4 limits of rectangle tube sheet respectively.
The invention has the beneficial effects as follows: the direct impact of steam to tube bank avoided in the design of special-shaped shell body top admission header large space fully; Adopt the U-shaped heat exchanger tube to make equipment not have thermal (temperature difference) stress fully; Owing to adopting the rectangle tube sheet, the mode of stringing can be determined horizontal cloth tube pitch according to the size of throttle flow on tube sheet, simultaneously so that steam along evenly entering tube bank in the scope of housing heat exchanger tube total length, the flow velocity that enters tube bank to satisfy steam can not impact tube bank.The shape of rectangle tube sheet and the spread pattern of heat exchanger tube make its heat transfer effect better, more compact structure, and can realize low drain approach heat exchange, steam saving consumption; The calandria structure of tube bank and rectangle support plate comprise ability that whole heat exchanger tube supporting forms make the anti-impact of tube bank to greatest extent and reach ambassador's equipment and can not destroy by vibration-generating, can adopt the more heat exchanger tube of thin-walled; The design of the large space of the hydrophobic header in special-shaped shell body bottom makes its hydrophobic control of being more convenient for can prevent effectively that drainage pump from finding time; The semicircular shell design of bobbin carriage can improve its bearing capacity; All-welded version makes the stronger structure of the equipment more reliable heat resisting and pressure resisting ability of sealing simpler, is the efficient energy-saving heat-exchange equipment of a kind of ideal.
