Abstract
The utility model relates to a tubular heat exchanger. The tubular heat exchanger is formed by mounting an end enclosure at each of the two ends of a heat exchanger tube body; a center tube, tube nests and spiral plates are mounted in the heat exchanger tube body; the spiral plates are mounted in an annular space between the center tube and the heat exchanger tube body; a spiral passage is defined by the center tube, the spiral plates and the heat exchanger tube body in the axial direction of the heat exchanger; the spiral plates are provided with elliptical holes; the tube nests penetrate through the elliptical holes on the spiral plates and are mounted in the spiral passage; and the tube nests are arranged in annular concentric circles along the axial line of the center tube. In the utility model, by using centrifugal force generated by the spiral passage for perturbing a heat exchanger interface, the heat exchange efficiency is increased, and the problem of low heat exchange efficiency of the existing tubular heat exchanger is solved.
Description
Technical field
The utility model belongs to the heat exchanger that carries out exchange heat in the petroleum chemical industry, and what be specifically related to is a kind of tubular heat exchanger.
Background technology
Tubular heat exchanger is a most popular heat exchange main equipment in the petroleum chemical industry, and it has advantages such as heat transfer efficiency height, compact conformation, manufacturing be simple.Tubular heat exchanger mostly is the smooth tubular type heat exchange structure that has two end sockets, and inlet, outlet are installed on the end socket, and inlet, outlet also are installed on the heat exchange cylindrical shell; Each tubulation is the light pipe that regular run-in index is arranged in the heat exchange cylindrical shell, like staggered square pitch or staggered triangular pitch, and no any annex on each tubulation outer wall.Because medium flows between pipe soon between managing, the time of staying is short, contact less with the tubulation outer surface and the time weak point, thereby heat exchange efficiency is lower.
Summary of the invention
The purpose of the utility model provides a kind of tubular heat exchanger, and it is used to solve the low problem of existing tubular heat exchanger heat exchange efficiency.
The utility model solves the technical scheme that its technical problem adopted: this tubular heat exchanger is respectively installed an end socket by heat exchange cylindrical shell two ends and is constituted; Central tube, tubulation, spiral plate are installed in the heat exchange cylindrical shell; In the annular space between central tube and the heat exchange cylindrical shell spiral plate is installed, central tube, spiral plate, heat exchange cylindrical shell one common peripheral have become along the helical duct on the heat exchanger axis direction; Spiral plate is provided with elliptical aperture, and the elliptical aperture that tubulation passes on the spiral plate is installed in the helical duct, and each tubulation is axis concentric circles one circle circle arrangement in the form of a ring with the central tube.
Beneficial effect:
1, utilizes the disturbance at the centrifugal force heat exchanging interface of helical duct generation in the utility model; Improved heat exchange efficiency, simultaneously, fluid flows along helical duct in shell side; Prolong the time of staying of medium in heat exchanger tube between pipe, also improved heat exchange efficiency accordingly.
2, the utility model spiral plate support tubulation has strengthened the tube bank rigidity, makes whole tube bank one integrated mass.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the interior tubulation arranged of heat exchange cylindrical shell in the utility model.
1 heat exchange cylindrical shell, 2 central tubes, 3 spiral plates, 4 tubulations.
The specific embodiment
In conjunction with accompanying drawing the utility model is further specified:
As shown in Figure 1, this tubular heat exchanger is respectively installed an end socket by heat exchange cylindrical shell 1 two ends and is constituted, and inlet, outlet are installed on the end socket, and inlet, outlet also are installed on the heat exchange cylindrical shell 1; Central tube 2, tubulation 4, spiral plate 3 are installed in the heat exchange cylindrical shell 1; In the annular space between central tube 2 and the heat exchange cylindrical shell 1 spiral plate 3 is installed; Central tube 2, spiral plate 3, heat exchange cylindrical shell 1 have surrounded along the helical duct on the heat exchanger axis direction jointly; Spiral plate 3 not only plays the effect of supporting tubulation 4, has also served as two walls of helical duct simultaneously, and the heat transferring medium that gets into from heat exchange cylindrical shell 1 flows along helical duct; Spiral plate 3 is provided with elliptical aperture, and the elliptical aperture that tubulation 4 passes on the spiral plate is installed in the helical duct.
Consult Fig. 2, each tubulation 4 is axis concentric circles one circle circle arrangement in the form of a ring with central tube 2, in this embodiment, is provided with two circle tubulations 4 in the heat exchange cylindrical shell 1.
The utility model helical flow path is the uiform section runner, and the transmittance process of a continous-stable is provided, and can improve the exchange capability of heat of heat exchanger.
