Abstract
The invention discloses a kind of shell side is from cooling protection movable tube sheets heat exchanger; heat exchanger high-temperature medium enters shell-side cylinder 2 from the shell side inlet 1 of shell-side cylinder 2; the coated inner wall heat-resistant lining 3 of shell-side cylinder 2; heat-resistant lining 3 extends to one end of insulating sleeve 6 from 1 end of shell side inlet, protects shell-side cylinder 2；Insulating sleeve 6 is welded on above the inwall of shell-side cylinder 2；High-temperature medium is entered behind circular passage in insulating sleeve 6 between 5 and shell-side cylinder 2 by raising the nose above water to breathe, lower the temperature after being exchanged heat with the cryogenic media in heat exchanger tube 7, shell side medium after cooling is redirected into the circular passage that insulating sleeve 6 and cylinder 2 are formed at tube sheet 8, along circular passage to 11 outflow heat exchanger of shell side media outlet；Cryogenic media enters tube side cylinder 9 from tube-side inlet 10, enters back into survey in heat exchanger tube 7 and is exchanged heat with shell side high-temperature medium, and after heat absorption, cryogenic media is converged in floating head 5, exports 4 outflow heat exchangers from tube side.
Description
Technical field
The present invention relates to a kind of shell side is from cooling protection movable tube sheets heat exchanger.
Background technology
With the raising of national requirements for environmental protection, the recycling of the energy is increasingly taken seriously, but high temperature or superhigh temperature band
The energy regenerating of pressure medium is more difficult, and it is limited to be largely determined by material bearing capacity in hot environment, particularly commonly
Metal material when temperature is more than more than 500 DEG C, its allowable design stress be only normal temperature when 1/3, even lower.When high temperature is situated between
When matter pressure is higher, heat transmission equipment material can be very thick, sometimes exceed current material production capacity, and high temperature can cause compared with
Big swelling stress, causes heat transmission equipment structure design realize.
Content of the invention
The technical problem to be solved in the present invention is a kind of shell side from cooling protection movable tube sheets heat exchanger, solves swelling stress.
In order to realize above-mentioned technology design, the technical scheme is that there is provided a kind of shell side from cooling protection floating head type
Heat exchanger, including shell-side cylinder 2, tube side cylinder 9 and tube sheet 8, the connection shell-side cylinder 2 of tube sheet 8 or so and tube side cylinder 9；Which is special
Levy and be：Heat exchanger high-temperature medium enters shell-side cylinder 2, the coated inner wall of shell-side cylinder 2 from the shell side inlet 1 of shell-side cylinder 2
Heat-resistant lining 3, heat-resistant lining 3 extend to one end of insulating sleeve 6 from 1 end of shell side inlet, protect shell-side cylinder 2；Every
Hot jacket cylinder 6 is welded on above the inwall of shell-side cylinder 2；High-temperature medium is entered behind circular passage between 5 and shell-side cylinder 2 by raising the nose above water to breathe
In insulating sleeve 6, with heat exchanger tube 7 in cryogenic media exchanged heat after lower the temperature, the shell side medium after cooling is turned at the tube sheet 8
The circular passage that insulating sleeve 6 and cylinder 2 are formed is entered, along circular passage to 11 outflow heat exchanger of shell side media outlet；Low temperature
Medium enters tube side cylinder 9 from tube-side inlet 10, enters back into survey in heat exchanger tube 7 and is exchanged heat with shell side high-temperature medium, after heat absorption
Cryogenic media exports 4 outflow heat exchangers in 5 interior convergences of raising the nose above water to breathe from tube side.
The present invention also has the advantages that：
1st, the heat exchanger adopts floating head type, it is to avoid equipment because of the expansion of heat exchanger tube, damage by caused local stress；
2nd, shell side inlet end applies heat proof material, it is to avoid cylinder is damaged by high-temperature medium；
3rd, shell side high-temperature medium first carries out heat exchange cooling on the inside of isolation sleeve, is redirected into outside insulating sleeve at tube sheet
Side, the low temperature shell side medium after cooling form self-shield effect in circular passage, it is to avoid shell-side cylinder receives high temperature failure.
Description of the drawings
Fig. 1 be shell side from cooling protection movable tube sheets heat exchanger schematic diagram.
Description of reference numerals：Shell side inlet 1, shell-side cylinder 2, heat-resistant lining 3, tube side outlet 4, raise the nose above water to breathe 5, insulating sleeve 6,
Heat exchanger tube 7, tube sheet 8, tube side cylinder 9, tube-side inlet 10, shell side media outlet 11.
Specific embodiment
For becoming apparent the present invention, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment

Heat-resistant lining 3, heat-resistant lining 3 extend to one end of insulating sleeve 6 from 1 end of shell side inlet, protect shell-side cylinder 2.Every
Above the inwall of the welding of hot jacket cylinder 6 and shell-side cylinder 2.High-temperature medium is entered behind circular passage between 5 and shell-side cylinder 2 by raising the nose above water to breathe
In insulating sleeve 6, with heat exchanger tube 7 in cryogenic media exchanged heat after lower the temperature, the shell side medium after cooling is turned at the tube sheet 8
The circular passage that insulating sleeve 6 and cylinder 2 are formed is entered, along circular passage to 11 outflow heat exchanger of shell side media outlet.
Cryogenic media enters tube side cylinder 9 from tube-side inlet 10, and entering back into survey in heat exchanger tube 7 is carried out with shell side high-temperature medium
Heat exchange, after heat absorption, cryogenic media exports 4 outflow heat exchangers in 5 interior convergences of raising the nose above water to breathe from tube side.
Shell side inlet 1 is less than the diameter of the straight section of shell-side cylinder 2, and shell side inlet 1 passes through a frustum of a cone with shell-side cylinder 2
Connection.
Expansion joint is provided between tube side outlet 4 and floating head 5, when 7 expanded by heating of heat exchanger tube is flexible, expansion joint will be played
