Abstract
The invention relates to a load distributing device used on heat exchange equipment, in particular to a high-voltage spiral tube type heat exchanger distributing device comprising a load distributing barrel arranged in a heat exchanger, a star-shaped support is fixedly installed on the lower bottom of the load distributing barrel, heterogenic butt strips are arranged on the outer surface of the load distributing barrel, and spiral heat exchange pipes are spirally arranged on the heterogenic butt strips along the outer surface of the load distributing barrel; a central barrel is installed in the load distributing barrel, the heterogenic butt strips are also arranged on the outer surface of the central barrel, and the spiral heat exchange pipes are also spirally arranged on the heterogenic butt strips along the outer surface of the central barrel; and openings are uniformly distributed on the surface of the load distributing barrel. The load distributing barrel, the star-shaped support and the heterogenic butt strips, which are arranged in the invention, are welded into a whole so that the integral strength and rigidity of the invention are greatly enhanced, and therefore, the design and the manufacture of a large-scale spiral tube type heat exchanger are realized; and the invention has the advantages of simple structure, convenient use and uniform load distribution.
Description
Technical field
The present invention relates to a kind of load distribution unit of on heat transmission equipment, using, particularly a kind of high-voltage spiral tube type heat exchanger distributing device.
Background technology
Usually, each medium channel on pipe type heat transfer equipment of high pressure, replace coiling by the different hand of spiral and form.Because the number of plies of main equipment is a lot, reach more than hundred layers, load is along with the increase of the number of plies, and the stress that particularly outer more layer load forms is big more.Make the intensity of whole heat transmission equipment can not satisfy instructions for use, the whole tube bank sinking that is in operation, the heat-transfer capability between medium greatly reduces, and the also corresponding increase of resistance causes whole equipment normally not move.This also is a design difficulty of the large-scale wound tube heat exchanger of long-term puzzlement.
Summary of the invention
The invention reside at the deficiency that exists in the above-mentioned background technology provides a kind of simple in structure, easy to use, load to scatter uniform high-voltage spiral tube type heat exchanger distributing device.
Technical scheme of the present invention is achieved in that and comprises the load distribution tube that is arranged in the heat exchanger, it is characterized in that:
Scatter on the going to the bottom of tube in load and to be installed with star-like support, scatter in load on the outer surface of tube and be furnished with special-shaped filler strip, the outer surface screw arrangement of scattering tube in special-shaped filler strip upper edge load has spiral heat exchange tube;
Scatter in the tube in load central tube is installed, on the outer surface of central tube, be furnished with special-shaped filler strip equally, spiral heat exchange tube is arranged in the same screw arrangement of outer surface of special-shaped filler strip upper edge central tube;
On the surface of load distribution tube, be evenly distributed with perforate.
Equally distributed perforate is circular hole or square type hole on the surface of load distribution tube.
On special-shaped filler strip, have the spill holddown groove thereon, in this spill holddown groove, install and fix spiral heat exchange tube according to the distance between the spiral heat exchange tube.
The aperture of equally distributed circular hole is φ 6mm on the surface of load distribution tube, and pitch-row is 60mm.
The aperture in equally distributed square type hole is 6 * 8mm on the surface of load distribution tube, and pitch-row is 60mm.
Scatter the tube outside in load and also be set with one deck load distribution tube at least.
The present invention will be welded as a whole with the load distribution tube in it, star-like support, special-shaped filler strip, make whole intensity, rigidity strengthen greatly, make the design of large-scale wound tube heat exchanger, manufacturing be achieved.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of high-voltage spiral tube type heat exchanger distributing device comprises the load distribution tube 1 that is arranged in the heat exchanger, it is characterized in that:
Scatter on the going to the bottom of tube 1 in load and to be installed with star-like support 2, scatter in load on the outer surface of tube 1 and be furnished with special-shaped filler strip 5, the outer surface screw arrangement of scattering tube 1 in special-shaped filler strip 5 upper edge load has spiral heat exchange tube 4;
Scatter in the tube 1 in load central tube 3 is installed, on the outer surface of central tube 3, be furnished with special-shaped filler strip 5 equally, spiral heat exchange tube 4 is arranged in the same screw arrangement of outer surface of special-shaped filler strip 5 upper edge central tubes 3;
On the surface of load distribution tube 1, be evenly distributed with perforate.
Equally distributed perforate is circular hole or square type hole on the surface of load distribution tube 1.
The aperture of equally distributed circular hole is φ 6mm on the surface of load distribution tube 1, and pitch-row is 60mm.
The aperture in equally distributed square type hole is 6 * 8mm on the surface of load distribution tube 1, and pitch-row is 60mm.
Scatter tube 1 outside in load and also be set with one deck load distribution tube at least.
Load is scattered tube 1 and is arranged in the heat exchanger, star-like support 2, special-shaped filler strip 5 and load are scattered to be between tube 1, the central tube 3 and are welded to connect, scatter tube 1 outside in load and also be set with one deck load distribution tube at least, promptly load is scattered tube 1 by certain number of plies setting.The distance that in addition then above-mentioned load is scattered the airflow hole on the tube 1 is relevant with the aperture.Equally distributed perforate is circular hole or square type hole on the surface of load distribution tube 1.
The present invention scatters tube 1 with load and is welded as a whole with special-shaped filler strip, not only significantly reduced the overload of central tube, make the intensity of whole heat-exchanging tube bundle, rigidity improves greatly, and, thoroughly eliminated the fluid bias current phenomenon that prior art causes because of load is excessive, make that the helical duct of every interlayer is basic identical, thereby the heat transfer efficiency of whole equipment has increased greatly.
