Description
Technical field
The utility model belongs to heat exchanger, more particularly to a kind of to need vertical cool process gas and produce steam
Heat exchanger.
Background technology
Usually need to cool down high-temperature gas in petrochemical industry, allow to use when gas temperature exceedes material
It is common apparatus-form using steam generator during temperature.Because high parameter, steam generator is key equipment.
Generally, the steam generator for the fixed tube sheet type that petrochemical industry is used all uses horizontal arrangement, its
Advantage is：Tube sheet be ensure that by the sufficiently cool of water, metal Wall Temperature is controllable.But needed in some special processes or arrangement
Ask down, it is necessary to using the pattern of vertical.In this case, there is upper perforated plate because of gas-liquid in fixed tube sheet type steam generator
Separation causes the phenomenon that gas phase is assembled, and now due to metal temperature and contact medium and heat transfer property, gas phase media conductivity of heat is poor,
Significantly raised close to tube side medium temperature so that being in contact with it side metal temperature；And tube side medium temperature is generally more than metal permission
Temperature in use, causes tube sheet cooling failure, acceleration equipment destruction.
Utility model content
The utility model provides a kind of vertical steam generator, it is to avoid shell side side upper perforated plate produces the phenomenon of gas phase aggregation.
The technical scheme that the utility model is used for：
A kind of vertical steam generator, including the pressure-bearing chamber that upper and lower bobbin carriage is constituted with shell side housing and three, the pressure-bearing
Heat exchanger tube is provided with by upper and lower tube sheet in chamber, the steam generator vertical, the upper and lower tube sheet, which has, is convex to shell
The circular arc turnup structure of journey side；The affixed formation of connector is imported and exported between upper and lower bobbin carriage and shell side housing by annular shell side to hold
Press chamber；The annular shell side is imported and exported and adapter hole is provided with the wall of connector, and there is the annular convex shoulder for stretching to shell side side its inner side；
The outer rim docking of the circular arc turnup structure of the annular convex shoulder and upper and lower tube sheet is affixed, on the inner surface for forming shell-side outlet adapter
Edge is concordant with shell side peak and the inner surface lower edge of shell side inlet adapter is concordant with shell side minimum point.
The arc radius of the circular arc flange of the upper and lower tube sheet is 3~4 times of tube plate thicknesses.
Cloth area under control on the upper and lower tube sheet uses planar structure.
Cloth area under control on the upper and lower tube sheet uses oval cross section structure.
The utility model employs the structure that the protrusion side of lower perforated plate is oppositely arranged, during equipment vertical, by annular
Shell side imports and exports connector and ensures shell-side outlet（Adapter inner surface peak）With enclosure interior（Tube sheet shell side side）Peak is put down
Together, the flow dead at the upper perforated plate back side can be eliminated, gas-phase product is guided to flowing at adapter, it is to avoid gas-liquid separation, ensures equipment
Safe operation.
The utility model produces the heat exchange occasion of steam mainly for vertical cool process gas is needed, it is adaptable to
The waste heat recovery of technical process process gas containing dust such as heavy oil conversion, coal gasification, dehydrating alkanes, methanol-to-olefins.

Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
Refering to Fig. 1, Fig. 2, a kind of vertical steam generator, including upper and lower bobbin carriage 21,22 and shell side housing 5 and three's group
Into pressure-bearing chamber, overall pressure-bearing chamber supports by skirt 6；Heat exchange is provided with by upper and lower tube sheet 3,7 in the pressure pocket room
Pipe 1, the steam generator vertical, the upper and lower tube sheet 3,7 has the circular arc turnup structure for being convex to shell side side；Upper, lower tube
The welding of connector 9 is imported and exported by annular shell side between case 21,22 and shell side housing 5 and forms pressure-bearing chamber；The annular shell side enters
Adapter hole 11 is equidistantly provided with the wall of outlet connector 9 it is used for butt welding connection shell side and imports and exports adapter, and its inner side has and stretched to
The annular convex shoulder 10 of shell side side；The outer rim butt welding of the circular arc turnup structure of the annular convex shoulder 10 and upper and lower tube sheet 3,7.Institute
The inner surface that endoporus is opened in the one end and annular shell side import and export connector 9 for stating annular convex shoulder 10 is concordant, and the other end is less than the ring
Shape shell side imports and exports the upper surface in the adapter hole being equidistantly provided with the wall of connector 9（The expression method is with the position shown in Fig. 4
It is defined）.The inner surface top edge for forming shell-side outlet adapter 4 is concordant with shell side peak, and such a setting can be by the gas at top
Along pipeline device for transferring, it is to avoid upper perforated plate shell side side produces the phenomenon of gas phase aggregation.And the inner surface of shell side inlet adapter 8 is following
Edge is concordant with shell side minimum point, it is ensured that avoid tube sheet lower plane hydrops, reduces the corrosion risk of Medium concentration.
