Description

Technical Field

[0001] This utility model relates to the field of regenerator technology, and in particular to a material regenerator. Background Technology

[0002] Industrial and oil refining operations generate a large amount of waste gas, one type of which is cyclohexane oxidation waste gas. This waste gas contains organic materials, which, if directly emitted, cause environmental pollution, but can be recycled and reused. Generally, cyclohexane oxidation waste gas is emitted directly, resulting in material waste and significant environmental pollution. To recover this organic material, specialized recovery equipment is required.

[0003] However, in the existing technology, at least the following technical problems have been found: the heat exchange efficiency of existing heat recovery devices is not high, and they cannot effectively recover the heat generated by large production equipment. To address this, we provide a material regenerator that uses two heat exchangers connected in series, which can improve the heat exchange rate, meet production needs, and save costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A material regenerator includes two sets of support legs, with a first housing fixedly connected to the top of each set of support legs. A connecting column is fixedly connected to the top of the first housing, and a second housing is welded to the top of the connecting column. A discharge port is connected to the left side of the first housing via a flange, and a feed port is connected to the side of the second housing near the discharge port via a flange. Sealing plates are sealed inside both ends of the first and second housings, and multiple heat exchange tubes are arranged between the sealing plates. Fixing components are respectively installed below one side of the first housing and above one side of the second housing. The first housing and the second housing are connected by a U-shaped connecting pipe via a fixing assembly. The first housing has a water outlet on the lower side near the discharge port, and the second housing has a water inlet on the upper side near the inlet port. Insert blocks are fixedly connected to the bottom and top of one side of the U-shaped connecting pipe, and a positioning hole is opened on one side of the insert block.

[0025] This application provides a material regenerator. By setting a fixing component, the U-shaped connecting pipe can be easily disassembled and assembled under the cooperation of a fixing block, a positioning rod, a connecting plate, and a restoring spring. This facilitates the internal flushing and maintenance of the heat exchange tube. By using a series connection of a first shell and a second shell, the heat exchange rate can be greatly improved, meeting production needs and saving costs. Example 1

[0026] The technical solution in this application embodiment effectively solves the problem that existing heat recovery devices have low heat exchange efficiency and cannot effectively recover heat generated by large-scale production equipment. The overall idea is as follows:

[0027] like Figures 1 to 4 To address the problems existing in the prior art, this utility model provides a material reheater, including support legs 1, of which two sets are provided, and a first housing 2 is fixedly connected to the top of the two sets of support legs 1. A connecting column 23 is fixedly connected to the top of the first housing 2, and a second housing 3 is welded to the top of the connecting column 23. A discharge port 21 is connected to the left side of the first housing 2 via a flange, and a feed port 31 is connected to the side of the second housing 3 near the discharge port 21 via a flange. Sealing plates 24 are respectively sealed and connected to the inside of both ends of the first housing 2 and the second housing 3. Multiple heat exchange tubes 25 are arranged between the 4. Fixing components 4 are respectively arranged on the lower side of one side of the first shell 2 and the upper side of one side of the second shell 3. The first shell 2 and the second shell 3 are connected by a U-shaped connecting pipe 5 through the fixing components 4. Multiple folding baffles 26 are sleeved on the outside of the heat exchange tubes 25 inside the first shell 2 and the second shell 3. A connecting pipe 33 is connected through the first shell 2 and the second shell 3. A water outlet 22 is arranged on the lower side of the first shell 2 near the discharge port 21. A water inlet 32 ​​is arranged on the upper side of the second shell 3 near the feed port 31.

[0028] By adopting the above technical solution, during use, when cooling the medium, the medium enters from the feed inlet 31, and cold water enters from the water inlet 32. The medium enters the U-shaped connecting pipe 5 from the heat exchange tube 25 inside the second shell 3, and then enters the heat exchange tube 25 inside the first shell 2, and finally exits from the discharge outlet 21. During this process, cold water enters the first shell 2 from the second shell 3 through the connecting pipe 33 via the baffle 26, and finally exits from the water outlet 22. The sealing plate 24 can prevent cold water from mixing with the medium, and the baffle 26 can prolong the time that cold water spends inside the first shell 2 and the second shell 3, so that the cold water can fully exchange heat with the medium inside the heat exchange tube 25. At the same time, the design of connecting the first shell 2 and the second shell 3 in series can effectively recover the heat in the medium and improve the energy utilization rate. Example 2

[0029] like Figures 1 to 4 A plug 51 is fixedly connected to the bottom and top of one side of the U-shaped connecting pipe 5. A positioning hole 52 is opened on one side of the plug 51. The fixing component 4 includes a fixing block 41. The fixing block 41 is fixedly installed on the bottom of the first housing 2 and the top of one side of the second housing 3. A positioning rod 42 is inserted into the middle of the fixing block 41. A connecting plate 43 is fixedly connected to one side of the positioning rod 42. A restoring spring 44 is fixedly connected to one side of the connecting plate 43.

[0030] By adopting the above technical solution, when the device is not in use, the positioning rods 42 below the first housing 2 and above the second housing 3 can be pulled simultaneously. The positioning rods 42 compress the restoring springs 44 until the bottom end of the positioning rods 42 disengages from the positioning hole 52 inside the insert block 51. Only then can the U-shaped connecting tube 5 be pulled to one side to remove it. The inside of the heat exchange tube 25 can be rinsed with a high-pressure water gun. Similarly, under the force of the restoring springs 44, the positioning rods 42 can be driven into the positioning hole 52 inside the insert block 51 to fix the U-shaped connecting tube 5.

[0031] Working principle: During operation, when cooling the medium, the medium enters through the feed inlet 31, while cold water enters through the water inlet 32. The medium enters the U-shaped connecting pipe 5 through the heat exchange tube 25 inside the second shell 3, then enters the heat exchange tube 25 inside the first shell 2, and finally exits from the discharge outlet 21. During this process, cold water enters the first shell 2 from inside the second shell 3 through the connecting pipe 33 via the baffle 26, and finally exits from the outlet 22. The sealing plate 24 prevents the cold water from mixing with the medium, and the baffle 26 prolongs the time the cold water spends inside the first shell 2 and the second shell 3, allowing the cold water to mix with the medium inside the heat exchange tube 25. The heat exchanger is divided into two parts. The design of connecting the first shell 2 and the second shell 3 in series can effectively recover heat from the medium and improve energy utilization. When the device is not in use, the positioning rods 42 below the first shell 2 and above the second shell 3 can be pulled at the same time. The positioning rods 42 compress the restoring spring 44 until the bottom end of the positioning rods 42 disengages from the positioning hole 52 inside the insert block 51. Then the U-shaped connecting tube 5 can be pulled to one side to remove it. The inside of the heat exchange tube 25 can be flushed with a high-pressure water gun. Similarly, under the action of the restoring spring 44, the positioning rods 42 can be driven into the positioning hole 52 inside the insert block 51 to fix the U-shaped connecting tube 5.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
