Abstract
The utility model relates to a novel heat exchanger for solar thermal power generation system. In solar thermal power generation system, because the irradiant nondeterminacy of the sun, heat exchanger has born great fatigue stress. Under this kind of operating mode, tube sheet thickness is great and the atress situation is extremely poor to adopt one. The utility model discloses the constitution includes: a set of hydroecium, piping, casing (16), strutting arrangement (8), the hydroecium pass through the piping with the casing with strutting arrangement connect, the hydroecium include water chamber head (1), barrel tip (2), hydroecium stack shell (3), pipe side outlet pipe (4), pipe side entrance pipe (15), water chamber head set up to be in one side of barrel tip, strutting arrangement set up to be in the casing between. The utility model discloses answer a novel heat exchanger for solar thermal power generation system.
Description
Technical field:
This utility model is related to a kind of novel heat exchanger for solar heat power generation system.
Background technology:
Heat exchanger main usess are by the heat transfer between two media, meet process system needs.Heat exchange
Device species is more, and the heat exchanger in large electric power plant, nuclear power plant typically adopts shell-and-tube at present.Because power plant system is run relatively
It is stable, in addition to the higher double reheat power generation sets of current parameter, the thermal (temperature difference) stress that heat exchanger bears and fatigue load are relative
Less, can adapt to thermoelectricity and the safe operation of nuclear power plant requires.
But in solar heat power generation system, fused-salt medium temperature may be up to 575 DEG C, and after a heat exchange, temperature is down to
450℃.Due to the uncertainty of solar irradiation, heat exchanger bears larger fatigue stress.Under this kind of operating mode, adopt one
Block tube plate thickness is larger and force-bearing situation extreme difference.
Content of the invention:
The purpose of this utility model is to provide a kind of novel heat exchanger for solar heat power generation system.
Above-mentioned purpose is realized by following technical scheme:
A kind of novel heat exchanger for solar heat power generation system, its composition includes: one group of hydroecium, piping, housing,

There is described tube side outlet, the hydroecium stack shell of bottom hydroecium is provided with described tube side inlet tube, described barrel end
It is arranged on the side of described hydroecium stack shell, described water chamber head is arranged on the side of described barrel end, described props up
Support arrangement is arranged between described housing.
The described novel heat exchanger for solar heat power generation system, described piping includes two tube sheets, bafflings
Plate, u-shaped heat exchanger tube, antihunting device, described tube sheet is connected using complete penetraction and fusion in welding with two hydroeciums, adopts with described u-shaped heat exchanger tube
Connected with eyelet welding, described deflection plate is distributed in described u-shaped heat exchanger tube, and described antihunting device is arranged on described u-shaped
In the middle part of the bend pipe of heat exchanger tube, described housing includes straight barrel one, shell-side inlet pipe, u-shaped cylinder, shell-side outlet pipe, straight barrel
Two, described straight barrel one, described straight barrel two adopts complete penetraction and fusion in welding structure even with described u-shaped cylinder and described tube sheet
Connect.
The beneficial effects of the utility model:
1. this utility model heat exchanger shell-side employs one kind by two hydroeciums, two straight section cylinders and the u welding therewith
The hairpin-type shell structure that type tube body is constituted, two hydroeciums, respectively with two straight section barrel solderings.Hydroecium is by barrel end, water
Room stack shell, tube sheet, the critical piece such as inlet/outlet pipe is constituted, and is no layered dividing plate, each hydroecium internal tube plate is heated evenly inside hydroecium,
No larger thermograde.
This utility model heat exchanger shell-side is made up of two straight barrels, a u-shaped cylinder and various adapter, adopts between cylinder
Use complete penetraction and fusion in welding welding structure, be provided with support meanss between two housings it is ensured that the rigid, stability of structure and good heat are swollen
Swollen property, afterbody u-shaped cylinder can be good at overcoming thermal expansion difference and thermal stress because upper-lower casing temperature difference difference leads to.
This utility model heat exchanger heat-exchanging tube adopts u shape pipe, and u shape pipe has the ability well adapting to thermal expansion in itself.
Heat exchanger tube is imported and exported and is adopted Inner Hole Welded Structure with the tube sheet in two hydroeciums respectively.This kind of structure well adapts to fatigue load
Effect, makes the leakage of heat exchange pipe end substantially reduce.Heat exchanger tube u-shaped pipe end is arranged in u-shaped cylinder, can arrange list inside heat exchanger
Arch, bouble-bow shape, annular, multiple baffling structure such as baffling rod-type.Fluid is in housing through deflection plate disturbance, abundant heat exchange.
This utility model heat exchanger is provided with antihunting device in u shape inner barrel, and antihunting device is made up of lamellar, clamping
Between heat exchanger tube, it is to avoid the excessive vibration causing of u shape pipe no-support spaning distance, heat exchanger can adapt to solar heat power generation system
In the big temperature difference and the coefficient operating mode of cyclic loading, shell-side resistance is little, and flow of media is smooth.
This utility model can reduce tube sheet and bear thermal (temperature difference) stress, effectively alleviate equipment thermal stress, and raising equipment bears fatigue
The ability of load, and improve equipment heat exchange efficiency, reduce drag losses.
