Abstract
The invention discloses a flat-spiral-tube type heat exchanger. The flat-spiral-tube type heat exchanger comprises a cylindrical shell, a cylindrical inner core, a medium in-out opening formed in the cylindrical shell and step-shaped hollow end sockets installed at the two ends of the cylindrical shell. An inlet is formed in one step-shaped hollow end socket, and an outlet is formed in the other step-shaped hollow end socket. Threads are arranged at the first steps and the second steps of the step-shaped hollow end sockets. The cylindrical inner core is composed of two circular end plates and a plurality of flat spiral tubes fixed between the two end plates. The two ends of the flat spiral tubes are in cylinder shapes with the length larger than the thickness of the circular end plates. Threads matched with the first steps of the step-shaped hollow end sockets are formed on the surfaces of the circular end plates. Outer threads matched with the second steps of the step-shaped hollow end sockets are arranged at the two ends of the cylindrical shell. According to the flat-spiral-tube type heat exchanger, the step-shaped hollow end sockets are adopted and internally and additionally provided with the threads, the step-shaped hollow end sockets are connected with the inner core and the cylindrical shell in a sealed mode through the threads accordingly, assembling is easy, and machining is convenient.
Description
Technical field
The present invention relates to the heat exchanger apparatus of chemical industry for exchange heat, be specifically related to a kind of flat-shaped spiral tube heat exchanger.
Background technology
The application of heat exchanger apparatus in chemical industry is comparatively general, mainly carries out exchange heat between different medium.Traditional heat exchanger mostly is shell-and-tube heat exchanger, and its shortcoming is that circulation medium needs higher degree of purity, otherwise easily results in blockage.Chinese patent grant number CN201740434U discloses a kind of spiral-plate heat exchanger, by curl that metallic plate is intervally arranged from inside to outside, but because its center is provided with straight plate, easily make fluid media (medium) form eddy current and cause resistance, and Long-Time Service can make metallic plate spacing distance inconsistent on the one hand, and then affect heat exchange efficiency, can corrosion of metal sheet be made on the other hand, cause dielectric leakage, affect equipment use effect and service life.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of flat-shaped spiral tube heat exchanger is provided.
The present invention is realized by following technical scheme: a kind of flat-shaped spiral tube heat exchanger, comprise cylindrical shell, column type inner core and the medium be placed on cylindrical shell are imported and exported and are installed on the stepped hollow termination at cylindrical shell two ends, one of them stepped hollow termination is provided with import, another stepped hollow termination is provided with outlet, single order and the second order place of stepped hollow termination are provided with screw thread, the flat-shaped helix tube that column type inner core is fixed between two end plates by two round shape end plates and several forms, the two ends of flat-shaped helix tube are that length is greater than the cylindrical of round shape end plate thickness, round shape end sheet surface is provided with the screw thread matched with the single order of stepped hollow termination, cylindrical shell two ends are provided with the external screw thread matched with the second order of stepped hollow termination.
Wherein, the external diameter of cylindrical shell equals the external diameter of stepped hollow termination, more attractive in appearance.
Preferred as such scheme, the second order length of described stepped hollow termination equals the thickness of round shape end plate.
Preferred as such scheme, the single order end place of described stepped hollow termination is provided with sealing ring, strengthens the sealing effectiveness of whole equipment, prevents the medium escape in hollow termination.
The invention has the advantages that: in the present invention, adopt flat-shaped volute design, increase the contact area of cold and hot medium, extend pipeline, and cushioning effect is played to the media flow in pipe, improve heat transfer effect and efficiency, adopt the hollow termination of staged and set up screw thread in the inner, making it be connected by thread seal with between inner core and cylindrical shell, assembling is simple, easy to process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of stepped hollow end head in the present invention.
In figure: 1, cylindrical shell; 2, stepped hollow termination; 3, round shape end plate; 4, sealing ring; 5, flat-shaped helix tube; 6, single order; 7, second order.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
As depicted in figs. 1 and 2, a kind of flat-shaped spiral tube heat exchanger, comprise cylindrical shell, column type inner core and the medium be placed on cylindrical shell are imported and exported and are installed on the stepped hollow termination at cylindrical shell two ends, one of them stepped hollow termination is provided with import, another stepped hollow termination is provided with outlet, single order and the second order place of stepped hollow termination are provided with screw thread, the flat-shaped helix tube that column type inner core is fixed between two end plates by two round shape end plates and several forms, the two ends of flat-shaped helix tube are that length is greater than the cylindrical of round shape end plate thickness, round shape end sheet surface is provided with the screw thread matched with the single order of stepped hollow termination, cylindrical shell two ends are provided with the external screw thread matched with the second order of stepped hollow termination, the second order length of stepped hollow termination equals the thickness of round shape end plate, the single order end place of stepped hollow termination is provided with sealing ring.
Above-described is only the preferred embodiment of a kind of spiral-plate heat exchanger of the present invention; it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
