Description

Special-shaped pipe plate structure

Technical Field

The utility model belongs to the technical field of heat exchanger, a multithread body is special-shaped tube plate structure for heat exchanger is related to.

Background

Currently, high pressure multi-fluid shell and tube heat exchangers often use a U-tube heat exchanger configuration. The tube box partition plate of the U-shaped tube type heat exchanger adopts a flat plate structure, the thickness of the tube box partition plate is very thick due to the high-pressure condition of a tube side medium, so that the tube box partition plate is difficult to weld and seal, even can not be designed and processed, and when temperature difference stress loads of tubes and a shell side are superposed, the tube plate and the connection of the tube plate with the tube box and a shell are very easy to lose effectiveness.

SUMMERY OF THE UTILITY MODEL

The utility model provides a special-shaped tube plate structure has realized high temperature, high pressure multifluid heat transfer.

The utility model aims at realizing through the following technical scheme:

a special-shaped tube plate structure comprises a tube plate main body, wherein an outer tube box connecting boss is arranged at the outer edge of one side end face of the tube plate main body, an inner tube box connecting boss is arranged in the center of the end face, and a space between the outer tube box connecting boss and the inner tube box connecting boss forms a heat transfer I area, namely an outer annular tube plate area; the space surrounded by the inner tube box and the lug boss forms a heat transfer area II, namely an inner tube plate area; an outer shell connecting boss is arranged on the outer edge of the end face of the other side of the tube plate main body; and heat exchange tube connecting tube holes are arranged on the tube plate main bodies in the heat transfer I area and the heat transfer II area.

The outer tube box connecting boss, the outer shell connecting boss and the inner tube box connecting boss are integrally manufactured with the tube plate main body.

The inner side of the root of the external pipe box connecting boss, the inner side of the root of the external shell connecting boss and the connecting parts of the two sides of the root of the internal pipe box connecting boss and the tube plate main body are all rounded.

The outer pipe box connecting boss, the outer shell connecting boss and the inner pipe box connecting boss are all in cylindrical connecting structures.

The utility model discloses be connected with interior pipe case, outer pipe case, outside casing and tube bank and can form multithread body heat transfer structure. And the structure is simple, the connection is convenient, the high-temperature and high-pressure working conditions can be borne, and the heat transfer of high-temperature and high-pressure multi-fluid is realized.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, a special-shaped tube plate structure comprises a tube plate main body, wherein an outer tube box connecting boss 1 is arranged at the outer edge of one side end face of the tube plate main body 5, an inner tube box connecting boss 2 is arranged at the center of the end face, and a heat transfer I area 6, namely an outer annular tube plate area, is formed in the space between the outer tube box connecting boss and the inner tube box connecting boss; the space surrounded by the inner tube box connecting boss 2 forms a heat transfer II area 7, namely an inner tube plate area; another of the tube plate main body 5

An outer shell connecting boss 3 is arranged on the outer edge of one side end face; and heat exchange tube connecting tube holes 4 are arranged on the tube plate main body 5 in the heat transfer I area 6 and the heat transfer II area 7. The heat transfer I area 6 and the heat transfer II area 7 respectively correspond to two tube pass fluids, and the tube pass fluids enter the tube bundle tube pass through the heat exchange tube connected with the tube plate main body 5 and transfer heat with the shell pass fluid.

The outer tube box connecting boss 1, the outer shell connecting boss 3, the inner tube box connecting boss 2 and the tube plate main body 5 are manufactured integrally. The pipe plate is effectively supported and strengthened, so that the pipe plate has better temperature resistance and pressure resistance.

The connecting part of the inner side of the root part of the external pipe box connecting boss 1 and the tube plate main body 5 is rounded, and the rounded corner of the connecting part is equivalent to a stress release groove and can effectively absorb the pressure stress and the temperature difference stress generated by the heat transfer I area fluid and the shell pass fluid at the tube plate part.

The connecting part of the inner side of the root of the external shell connecting boss 3 and the tube plate main body 5 is rounded, and the rounded angle at the connecting part is equivalent to a stress release groove, so that the pressure stress and the temperature difference stress generated by shell side fluid and heat transfer I area fluid at the tube plate part can be effectively absorbed.

The connecting parts of the two sides of the root part of the inner tube box connecting boss 2 and the tube plate main body 5 are rounded, and the rounded corners at the two sides of the connecting part are equivalent to stress release grooves, so that the pressure stress and the temperature difference stress generated by the heat transfer I area, the heat transfer II area and the shell pass fluid at the tube plate part can be effectively absorbed.

The external pipe box connecting boss 1, the external shell connecting boss 3 and the internal pipe box connecting boss 2 are all in a cylindrical connecting structure. Utilize the good advantage of gyration shell pressure resistance, guaranteed the utility model discloses a high pressure resistant and sealing performance.

The utility model discloses a use method:

the external pipe box connecting boss part 1 is connected with the external pipe box, the internal pipe box connecting boss part 2 is connected with the internal pipe box, the external shell connecting boss part 3 is connected with the shell, the heat exchange pipe connecting pipe hole 4 is connected with the heat exchange pipe of the heat transfer pipe bundle, one cold flow enters the heat transfer I area 6 from the external pipe box and is transferred with the shell side heat flow, the other cold flow enters the heat transfer II area 7 from the internal pipe box and is transferred with the shell side heat flow, and finally, the heat transfer of two cold flows and one heat flow in one device is realized.
