Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger equipment, in particular to a jet-type high-efficiency and energy-saving heat exchange device. Background Art

[0002] Heat exchanger is an important heat transfer device. Its core function is to transfer part of the heat of hot fluid to cold fluid. Its basic structure usually includes a large closed container filled with water or other media, and a pipe passing through the container to allow hot water to flow through the pipe.

[0003] By using a special grid or a perforated tube, the heat medium is directly sprayed from the normal direction onto the metal surface of the heat exchanger, or a cold fluid medium is sprayed onto the heat exchange surface at high speed. Due to the impact, turbulence is generated, thereby enhancing the heat exchange effect and improving the thermal efficiency. For example, the Chinese utility model patent disclosed by the publication number CN206192151U: a pin sleeve jet heat exchanger, the application is based on the comprehensive application of two major heat exchange enhancement technologies, pins and jets, and its flue gas resistance is small and the pin sleeve has the characteristics of anti-scaling, anti-ashing and self-cleaning. When the flue gas and the cold fluid are exchanged for heat, the application is the same as the existing heat exchange equipment. Since the flue gas enters from one end of the heat exchanger and is discharged from the other end of the heat exchanger, the heat exchange temperature of the cold fluid near the flue gas inlet end of the heat exchange tube in the heat exchanger is higher, while the heat exchange temperature of the cold fluid near the flue gas discharge port end is lower. Therefore, after the heat exchange of the cold fluid in the two parts of the heat exchanger is completed, the heat exchange temperature of the cold fluid cannot be adjusted according to the actual use requirements, that is, fluids of different temperatures cannot be obtained.

One end of the heat exchange tube 8 is connected to the cavity of the air inlet pipe 4 through one of the end covers 3, and the other end of the heat exchange tube 8 is connected to the cavity of the air outlet pipe 5 through the other end cover 3. An ejector 9 is fixedly installed between the plurality of heat exchange tubes 8. The ejector 9 includes an outer tube 10, and a plurality of inner tubes 11 are fixedly installed in the outer tube 10. Sealing plates 12 are fixedly installed on both sides of the inner tube 11, and a plurality of turbulent tubes 13 are fixedly installed on one side of the sealing plate 12.

[0024] like Figure 2-Figure 3 As shown, a connection port 14 is opened in the middle of the upper end of the outer tube 10 , that is, the cavity between the outer tube 10 and the inner tube 11 and the turbulence tube 13 is connected to the water inlet pipe 6 through the connection port 14 .

[0025] like Figure 2-Figure 5 As shown, a plurality of nozzles 15 are fixedly installed on the inner side of the turbulence tube 13, and a sealing ring 16 is fixedly connected between two adjacent turbulence tubes 13 at the same level, and the inner diameter of the sealing ring 16 is the same as the diameter of the heat exchange tube 8. A plurality of groups of inner tubes 11, sealing plates 12, and turbulence tubes 13 are arranged in the outer tube 10, and the two turbulence tubes 13 are connected by the sealing ring 16, so that the heat exchange medium in the outer tube 10 can be sprayed into the turbulence tube 13 and the inner tube 11 through the plurality of nozzles 15, so that the heat exchange efficiency can be improved by cooperating with the inner tube 11, and the medium of different temperatures can be diverted and used according to the use requirements, and a connecting seat 17 is fixedly connected between the middle part of the lower end of the inner tube 11 and the outer tube 10, and is located directly above the connecting seat 17. The inner tube 11 is provided with a drainage hole 18, and a positioning groove 19 is provided in the connecting seat 17.

A connecting seat 17 is fixedly connected between the inner tube 11 and the outer tube 10, which is conducive to the discharge of the medium in the inner tube 11 through the drainage pipe 20. The setting of the guide pipe 21 can seal the connection between the outer tube 10 after it is inserted and installed in the heat exchanger shell 1, so as to ensure the stable heat exchange of the medium. The inner tube 11, the sealing plate 12, the turbulence pipe 13, and the sealing ring 16 are inserted on the outside of the corresponding heat exchange tube 8.

[0026] It should be noted that the utility model is a jet-type high-efficiency and energy-saving heat exchange device.

After the cold fluid contacts the heat exchange tubes 8 located in the inner tube 11 and the turbulence tubes 13, the heat exchange can be carried out with the heat exchange tubes 8 and the high-temperature flue gas. At this time, the nozzle 15 continues to spray the cold fluid into the turbulence tubes 13 and the inner tube 11. The fluid micro-groups move irregularly in the turbulent state, and the particles are mixed, which can significantly improve the heat exchange rate. At the same time, the turbulence makes the flow velocity distribution more uniform, increases the contact area between the fluid and the heat exchange surface, and thus improves the heat exchange efficiency. The fluid after heat exchange can be discharged through the drainage hole 18 and the guide tube 21, and can be transferred to the required place in cooperation with the connecting pipe, so that according to the distance from the intake pipe 4, fluids of different temperatures can be obtained through multiple groups of inner tubes 11, sealing plates 12, turbulence tubes 13 and other structures.
