Description

Technical Field

[0001] The present application relates to the field of heat energy recovery technology, and in particular to a high-pressure machine waste heat recovery device. Background Art

[0002] As a common industrial equipment, high-pressure presses are widely used in many fields. In the Coca-Cola production process, high-pressure presses can compress carbon dioxide gas to a higher pressure, allowing it to better dissolve in the beverage and achieve carbonation, thus giving Coca-Cola its unique bubbly taste.

[0003] During the operation of a high-pressure compressor, the compressed gas causes a significant temperature increase. This temperature increase prevents further compression of the gas. To achieve the required compression ratio, the high-pressure compressor must be cooled. To recover heat energy, a heat exchanger is often installed in the high-pressure compressor's cooling system. This heat exchanger exchanges heat between the high-temperature coolant or lubricating oil and a low-temperature medium (such as water). The heated medium can then be used for heating, hot water supply, or other processes requiring heat energy.

[0004] However, after long-term use, scale or corrosion will form on the inner wall of the heat exchange tube of the heat exchanger, affecting the heat exchange effect and the service life of the heat exchange tube. Since the heat exchange tube and the heat exchange box of the heat exchanger are fixed by welding in the prior art, it is difficult to replace the heat exchange tube when the heat exchange tube is corroded and damaged. The entire heat exchanger can only be scrapped and replaced, resulting in increased production costs. Summary of the Invention

[0028] like Figure 1 and Figure 2As shown, the present application provides a high-pressure machine waste heat recovery device, including a heat exchange box 1, the top of the heat exchange box 1 is provided with an opening, the opening is detachably connected to a hanger 2, the hanger 2 is provided with a box cover 3, one side of the hanger 2 is provided with a water inlet pipe 4, the other side of the hanger 2 is provided with a water outlet pipe 5, a heat exchange tube 6 is provided in the heat exchange box 1, one end of the heat exchange tube 6 passes through one side of the hanger 2 and is connected to the water inlet pipe 4, the other end of the heat exchange tube 6 passes through the other side of the hanger 2 and is connected to the water outlet pipe 5, one side of the heat exchange box 1 is provided with a water inlet 7 and a water outlet 8, the water inlet 7 is located below the water outlet 8, and the hanger 2 is provided with a locking assembly 9 for locking the hanger 2 on the heat exchange box 1. Specifically, low-temperature cooling water is input into the heat exchange box 1 through the water inlet 7, and the high-temperature cooling water of the high-pressure machine is cooled by the water. The cooling liquid enters the heat exchange tube 6 through the water inlet pipe 4 and exchanges heat with the low-temperature cooling water in the heat exchange box 1. The high-temperature cooling liquid is discharged from the water outlet pipe 5 after being cooled by heat exchange, and the low-temperature cooling water is discharged from the water outlet 8 after being heated by heat exchange. When the heat exchange tube 6 needs to be replaced, the input of low-temperature cooling water and high-temperature cooling liquid is stopped, the locking component 9 is loosened, and then the hanger 2 is lifted upward to separate the heat exchange box 1 from the hanger 2. The hanger 2 is lifted and taken out of the heat exchange box 1 together with the heat exchange tube 6. A new hanger 2 and heat exchange tube 6 are replaced and then put into the heat exchange box 1. The hanger 2 is locked on the heat exchange box 1 by the locking component 9 to realize the replacement of the heat exchange tube 6 and the hanger 2. Compared with the existing technology, there is no need to scrap the entire heat exchanger for replacement, thereby avoiding increased production costs.

[0029] like Figure 1 and Figure 2 As shown, the locking assembly 9 includes a first locking bolt 91 and a second locking bolt 92. The first locking bolt 91 and the second locking bolt 92 are symmetrically arranged. The hanger 2 is provided with a first threaded through hole 21 adapted to the first locking bolt 91, and the hanger 2 is provided with a second threaded through hole 22 adapted to the second locking bolt 92. The first locking bolt 91 is threadedly connected to the first threaded through hole 21, and the end of the first locking bolt 91 abuts against the heat exchange box 1. The second locking bolt 92 is threadedly connected to the second threaded through hole 22, and the end of the second locking bolt 92 abuts against the heat exchange box 1. By rotating the first locking bolt 91 and the second locking bolt 92, the ends of the first locking bolt 91 and the second locking bolt 92 can be made close to or away from the heat exchange box 1. When the first locking bolt 91 and the second locking bolt 92 are close to the heat exchange box 1 and abut against the heat exchange box 1, the hanger 2 can be locked on the heat exchange box 1.

[0030] like Figure 2 As shown, a first sealing ring 10 is provided at the connection between the heat exchange tube 6 and the hanger 2. The first sealing ring 10 prevents the heat in the heat exchange box 1 from leaking from the gap between the heat exchange tube 6 and the hanger 2, thereby preventing heat loss.

[0031] like Figure 2As shown, a second sealing ring 11 is provided at the connection between the hanger 2 and the heat exchange box 1. The second sealing ring 11 is fixed on the heat exchange box 1. The setting of the second sealing ring 11 prevents the heat in the heat exchange box 1 from leaking from the gap between the hanger 2 and the heat exchange box 1, thereby preventing heat loss.

[0032] like Figure 2 As shown, the box cover 3 is threadedly connected to the hanger 2. Specifically, an inspection port is provided on the hanger 2, and an external thread is provided at the inspection port. The hanger 2 is provided with an internal thread. The internal thread and the external thread are adapted to each other, which facilitates the opening of the box cover 3 and allows regular inspection of scaling or corrosion inside the heat exchange box 1.

[0033] like Figure 2 As shown, a drain pipe 12 is connected to the bottom of the heat exchange box 1, and a drain valve 13 is provided on the drain pipe 12. When the scale in the heat exchange box 1 needs to be cleaned, the box cover 3 is opened, and a cleaning tool is used to reach into the heat exchange box 1 to clean the heat exchange box 1. Then, the drain valve 13 is opened to discharge the scale in the heat exchange box 1 through the drain pipe 12, which can extend the service life of the heat exchange box 1.

[0034] like Figure 1 and Figure 2 As shown, a plurality of heat exchange tubes 6 are provided, and the plurality of heat exchange tubes 6 are arranged in a row. The arrangement of the plurality of heat exchange tubes 6 improves the heat exchange efficiency.

[0035] like Figure 1 As shown, a flow regulating valve 14 is provided on the water inlet pipe 4, and a pressure detection gauge 15 is provided on the water outlet pipe 5. The pressure detection gauge 15 detects the water flow pressure output from the water outlet pipe 5, and the flow regulating valve 14 is adjusted according to the water flow pressure to control the flow rate of the high-temperature cooling water entering the heat exchange tube 6, so as to avoid pressure imbalance in the heat exchange tube 6, which may cause damage to the heat exchange tube 6 and affect the heat exchange performance.

[0036] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
