Description

Technical Field

[0001] The utility model relates to a water-cooling tube-in-tube water circulation structure, belonging to the technical field of heat exchange devices. Background Art

[0002] Water-cooled pipes are a type of heat exchange device commonly used in coking plants and steel plants, and are mainly used to exchange heat and cool materials. The water-cooled pipes include an inner pipe and an outer pipe, with a gap between the inner and outer pipes and an interlayer on the outer pipe. When in use, the material passes through the gap between the inner and outer pipes, and circulating cooling water is introduced into the inner and outer interlayers to exchange heat with the material.

[0003] The inner tube of the existing water cooling tube is as follows Figure 5 As shown, a partition plate 3 is provided in the inner tube, which divides the inner tube into two connected parts. The cooling water enters from the inlet on one side, bypasses the partition plate 3 and is discharged from the outlet on the other side, thereby increasing the flow distance of the cooling water in the inner tube. When processing this structure, an opening needs to be cut on the wall of the inner tube, and then the partition plate is inserted into the opening for welding. When in use, due to the influence of temperature changes, the weld at the opening is prone to cracking, causing cooling water to leak out, affecting production. Utility Model Content

[0006] The technical solution of the utility model is to provide a water-cooling tube inner tube water circulation structure, in which a guide tube is provided in the inner tube, and water circulation inside the inner tube is completed through the guide tube, without the need to open and weld the inner tube, thereby avoiding the problem of cracking of the inner tube due to temperature influence.

[0007] Preferably, a plurality of fins are provided on the outer wall of the inner tube for supporting the inner tube after installation.

[0008] Preferably, an outer tube connecting pipe is fixed to one end of the inner tube, the outer tube connecting pipe is sleeved on the outside of the inner tube, a circular flange is provided at one end of the outer tube connecting pipe for connecting to the outer tube, and a square flange is provided at the other end of the outer tube connecting pipe for connecting to other equipment.

[0009] Furthermore, the outer tube connecting pipe is provided with an interlayer for passing cooling water to perform heat exchange and cooling of the material close to the outside.

[0010] Preferably, the water inlet and the water outlet of the inner tube are both located at the same end of the inner tube, and the water inlet and the water outlet both penetrate the outer wall of the outer tube connecting tube.

[0011] Preferably, one end of the inner tube close to the outer tube connecting tube is conical to prevent material retention.
