Abstract
A kind of quenching waste heat boiler heat exchange segment structure, by upper header, boundling double-jacket tube and lower collecting box are constituted；Upper header and lower collecting box enter (go out) mouth pipe etc. and constitute by upper lower perforated plate, inner/outer tube, flange and cold water (steam)；Boundling double-jacket tube is made up of outer tube and inner tube etc.；Four tube sheets of upper and lower header are all using flexibility (thin) tube sheet of flange；All it is that plane tube sheet is different from other three tube sheets, the upper perforated plate of upper header is sphere tube sheet, and the distance between sphere tube sheet bottom and lower perforated plate are approximately equal to diameter of inner pipe size；The beneficial effect of the invention, one is that the upper perforated plate of upper header is changed to sphere tube sheet, forms the guide mechanism that steam flow to sphere eminence, it is to avoid the generation of the tube sheet surface excessively slow phenomenon of steam flow velocity, protects boiler entirety heat pipe from mistake cause thermal damage；Two be four tube sheets of upper and lower header all using flexible (thin) tube sheet, in addition to mitigating tube sheet weight, mainly can absorbing structure thermal stress, can effectively protect upper and lower header from thermal stress damage.
Description
Technical field
The present invention relates to the upper and lower header quenching waste heat boiler of a kind of chemical industry equipment, especially boundling double-jacket tube.
Background technology
Prior art (the patent No.：201310245480.3) quenching waste heat boiler is on the first line of a couplet box structure of heat exchanging segment,
Common upper perforated plate is changed to dish type upper perforated plate, the height of upper header moisture outlet is improve whereby and is reduced between lower perforated plate
Distance, this improvement makes the heat pipe of boiler that the probability step-down of cause thermal damage occur in upper header.But, in prior art
The upper perforated plate of header is still the plane tube sheet being horizontally mounted, and the outer cylinder around upper perforated plate is very big, and girth has four or five meters, and on
The moisture outlet of header only has three points, steam outwardly in it is larger near the flow velocity difference of outer cylinder barrel each point, lean on
Closely the flow velocity of outlet wants fast some pressure also lower, and the flow velocity away from outlet wants slow some pressure also higher, flat tube sheet pair
The flowing of steam does not have any guide mechanism, and where the low steam of pressure is easy for where flowing and flow velocity is also fast, otherwise which
In pressure it is high where flow velocity is just slow, the excessively slow local heat pipe of flow velocity still has and the possibility of cause thermal damage occurred, it is impossible on ensuring
The safety of header entirety heat pipe.
The content of the invention
In order to solve the above problems, the present invention try to allow upper header steam when pressing close to upper perforated plate and flowing, can four sides eight
Square olderly flowage, promotes steam flow velocity to homogenize, it is to avoid any one piece of region has the excessively slow phenomenon of flow velocity to produce.
The technical solution adopted for the present invention to solve the technical problems is：A kind of quenching waste heat boiler heat exchange segment structure,
By upper header, boundling double-jacket tube and lower collecting box are constituted；Upper header by upper perforated plate, lower perforated plate, inner cylinder, outer barrel, moisture outlet pipe and
Upper flange etc. is constituted, and upper perforated plate is welded by inner cylinder with upper flange；Lower perforated plate is also welded by outer barrel with upper flange；Lower collecting box by
Upper perforated plate X, lower perforated plate X, inner cylinder X, outer barrel X, cold water inlet tube and lower flange etc. are constituted, and upper perforated plate X passes through outer barrel X and lower flange
Welding；Lower perforated plate X is also welded by inner cylinder X with lower flange；Boundling double-jacket tube is made up of outer tube and inner tube etc.；Boundling double-jacket tube
The upper end of inner tube is welded with the upper perforated plate of upper header, and lower end is welded with the lower perforated plate X of lower collecting box；The outer tube of boundling double-jacket tube it is upper
Welded with the upper perforated plate X of lower collecting box end and the down tube plate weld of upper header, lower end；It is characterized in that：The upper perforated plate of upper header is with
Tube sheet, the upper perforated plate X and lower perforated plate X of lower collecting box are using flexibility (thin) tube sheet of flange；With other three tube sheets flange with
All it is inside different plane tube sheet, the upper perforated plate of upper header is sphere tube sheet within flange.
Beneficial effects of the present invention, one is that the upper perforated plate of upper header is changed to spherical plate by flat board, and the lighter steam of proportion is leaned on
Buoyancy-driven can be walked towards the eminence of sphere, thus form guide mechanism, it is to avoid any one has the excessively slow phenomenon of flow velocity to produce on tube sheet
It is raw, it is ensured that upper header entirety heat pipe is from crossing cause thermal damage.Two be upper and lower header four tube sheets by standard thickness tube sheet be changed to it is soft
Property (thin) tube sheet, except mitigate tube sheet weight in addition to, mainly can absorbing structure thermal stress, can effectively protect upper and lower header from heat
Stress damage.

Specific embodiment
Quenching waste heat boiler of the present invention exchanges heat segment structure, by upper header (1.), boundling double-jacket tube (2.) and lower collecting box
(3.) constitute；Upper header is by upper perforated plate (1), lower perforated plate (2), inner cylinder (3), outer barrel (4), moisture outlet pipe (5) and upper flange (6)
Deng composition；Boundling double-jacket tube is made up of outer tube (13) and inner tube (14) etc.；Lower collecting box is by upper perforated plate X (7), lower perforated plate X (8), interior
The composition such as cylinder X (9), outer barrel X (10), cold water inlet tube (11) and lower flange (12).
Four tube sheets of upper header and lower collecting box carry out wall thickness design by light wall pipe plate theory, so not single to save material
Material, moreover it is possible to absorb the thermal stress of boiler heat exchange segment structure.
