Description

Technical Field

[0001] This utility model relates to the technical field of heat exchangers for gas compressors, specifically a heat exchanger for a gas compressor. Background Technology

[0002] The heat exchanger of a gas compressor achieves a cooling effect by transferring heat from one fluid to another, thereby protecting the equipment from overheating damage.

[0003] For example, a heat exchanger for a gas compressor with authorization announcement number "CN218376803U" has a corresponding magnet b installed in the inner cavity of the support cover. The magnet a on the upper part of the core has opposite polarities to the opposite face of magnet b, while the magnet a on the lower part of the core has the same polarity to the opposite face of magnet b. The buoyancy generated by magnet a and magnet b can counteract the weight of the core. By setting the support cover and magnets b and a, the core is suspended in the heat exchanger in the heat exchange oil tank. This heat exchanger has better isolation of vibration and noise. However, in the use of the heat exchanger for the gas compressor, the compressed gas generated during the operation of the gas compressor carries high temperature and enters the heat exchanger to contact the heat exchange tubes. The heat is transferred to the internal water source through the heat exchange tubes to realize the heat exchange of the gas compressor. However, the temperature difference between the high temperature gas and the low temperature medium (such as cooling water) in the heat exchanger may cause uneven thermal expansion of the metal parts, generating thermal stress. Long-term operation can easily lead to fatigue cracking of the tube bundle or plate, affecting the normal support of the heat exchange tubes inside the heat exchanger of the gas compressor and increasing the vibration of the heat exchange tubes. Utility Model Content

[0004] The purpose of this invention is to solve the problem of increased vibration of the heat exchange tubes inside the heat exchanger of a gas compressor, which affects the normal support of the heat exchange tubes. Therefore, this invention proposes a heat exchanger for a gas compressor.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a heat exchanger for a gas compressor, including a shell and a first straight tube. The upper rear end face of the shell is connected to the front face of the first straight tube. A second straight tube is connected to the lower front face of the shell. A curved tube is provided inside the shell. A support structure is connected to the outer wall of the curved tube. Opening and closing structures are connected to the left and right sides of the shell respectively. The front of the outer wall of the curved tube is fixedly connected to the circular opening on the front face of the shell.

[0007] Preferably, the support structure includes a first bracket and a second bracket. The outer wall groove of the first bracket is inserted into the outer wall of the curved tube. The outer wall of the first bracket is in contact with the outer wall of the second bracket. The outer wall groove of the second bracket is inserted into the outer wall of the curved tube. A first bolt is threaded onto the outer wall of the second bracket. A square plate is fixed to the bottom of the outer wall of the second bracket. A second bolt is threaded onto the inner wall of the square plate.

[0008] Preferably, the outer end of the first bolt is threaded to the outer wall of the first bracket, and the bottom of the outer wall of the second bolt is threaded to the bottom of the inner wall of the outer casing.

[0009] Preferably, protective pads are fixed to the left and right sides of the outer shell respectively.

[0010] Preferably, the opening and closing structure includes a frame and a door panel. The outer wall of the frame is inserted into the opening of the outer wall of the outer shell. The outer side of the frame is fixedly connected to the inner side of the door panel. Vertical plates are fixedly connected to the upper and lower sides of the door panel respectively. A third bolt is threadedly connected to the inner wall of the vertical plate.

[0011] Preferably, the inner side of the outer wall of the third bolt is threaded to the outer wall of the outer casing, and a handle is fixedly connected to the outer wall of the door panel.

[0012] The present invention provides a heat exchanger for a gas compressor, which has the following advantages: After the first and second supports in the support structure crack and break, the third bolt is rotated outward through the vertical plate, causing it to detach from the outer wall opening of the outer casing. Then, the handle is grasped and the door panel is pulled outward, causing the door panel and frame to detach from the outer wall opening. Next, the first bolt is rotated outward through the second support, detaching from the first support. The first support is then removed from the outer casing. Subsequently, the second bolt is rotated upward through the square plate, detaching from the bottom of the inner wall of the outer casing. The second support is then removed from the outer casing. New first and second supports are then installed using the above operations. This achieves the replacement of the internal heat exchange tubes of the heat exchanger, ensuring normal support of the internal heat exchange tubes of the gas compressor and reducing the vibration of the heat exchange tubes.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Please see Figure 1-6 In this embodiment, a heat exchanger for a gas compressor includes a housing 1 and a first straight pipe 4. The upper rear end face of the housing 1 is connected to the front face of the first straight pipe 4, which is a flue gas inlet. A second straight pipe 5 is connected to the lower front face of the housing 1, which is a flue gas outlet. A curved pipe 6 is provided inside the housing 1. A water inlet is located above the front face of the curved pipe 6, and a water outlet is located below the front face of the curved pipe 6. A support structure 2 is connected to the outer wall of the curved pipe 6. Opening and closing structures 3 are connected to the left and right sides of the housing 1, respectively. The front of the outer wall of the curved pipe 6 is fixedly connected to the circular opening on the front face of the housing 1.

[0022] The support structure 2 includes a first bracket 201 and a second bracket 202. The outer wall groove of the first bracket 201 is inserted into the outer wall of the curved tube 6. The outer wall of the first bracket 201 is in contact with the outer wall of the second bracket 202. The outer wall groove of the second bracket 202 is inserted into the outer wall of the curved tube 6. A first bolt 203 is threaded on the outer wall of the second bracket 202. The first bolt 203 fixes the first bracket 201 and the second bracket 202. A square plate 204 is fixed to the bottom of the outer wall of the second bracket 202. A second bolt 205 is threaded on the inner wall of the square plate 204. The outer end of the first bolt 203 is threaded on the outer wall of the first bracket 201. The second bolt 205 fixes the square plate 204 and the outer shell 1. The bottom of the outer wall of the second bolt 205 is threaded on the bottom of the inner wall of the outer shell 1.

[0023] After the first bracket 201 and the second bracket 202 in the support structure 2 crack and are damaged, the third bolt 304 is rotated outward through the vertical plate 303, causing the third bolt 304 to disengage from the outer wall opening of the outer shell 1. Then, the handle 8 is grasped and the door panel 302 is pulled outward, causing the door panel 302 and the frame 301 to disengage from the outer wall opening of the outer shell 1. Next, the first bolt 203 is rotated outward through the second bracket 202 to disengage from the first bracket 201. Then, the first bracket 201 is removed from the outer shell 1. Subsequently, the second bolt 205 is rotated upward through the square plate 204, causing the second bolt 205 to disengage from the bottom of the inner wall of the outer shell 1. Then, the second bracket 202 is removed from the outer shell 1. Then, the new first bracket 201 and the second bracket 202 are installed. The above operation is performed to replace the support of the heat exchange tube inside the heat exchanger, ensuring the normal support of the heat exchange tube inside the gas compressor heat exchanger and reducing the vibration of the heat exchange tube.

[0024] Pads 7, made of rubber, are fixedly attached to the left and right sides of the outer casing 1. The opening and closing structure 3 includes a frame 301 and a door panel 302. The outer wall of the frame 301 is inserted into the opening of the outer wall of the outer casing 1. The outer side of the frame 301 is fixedly attached to the inner side of the door panel 302. Vertical plates 303 are fixedly attached to the upper and lower sides of the door panel 302. A third bolt 304 is threadedly connected to the inner wall of the vertical plate 303. The third bolt 304 fixes the vertical plate 303 and the outer casing 1. The inner side of the outer wall of the third bolt 304 is threadedly connected to the outer wall of the outer casing 1. A handle 8 is fixedly attached to the outer wall of the door panel 302. The handle 8 facilitates the pulling of the door panel 302.

[0025] Working principle:

[0026] Heat exchanger installation for gas compressors:

[0027] The outer wall groove of the first bracket 201 is inserted into the left side of the outer wall of the curved tube 6, and then the outer wall groove of the second bracket 202 is inserted into the right side of the outer wall of the curved tube 6. At this time, the right side of the first bracket 201 and the left side of the second bracket 202 are in contact with each other, and the bottom of the square plate 204 is in contact with the bottom of the inner wall of the outer shell 1. Then, the first bolt 203 is rotated to the left through the second bracket 202, so that the left side of the outer wall of the first bolt 203 is connected to the round thread of the outer wall of the first bracket 201, completing the docking of the two brackets. Then, the second bolt 205 passes through the square plate 204 from top to bottom and is connected to the round thread of the bottom of the inner wall of the outer shell 1. The connection is completed, the bracket is fixed, and then the curved pipe 6 is supported by the first bracket 201 and the second bracket 202, so that the outer wall of the frame 301 is inserted into the outer wall opening of the outer shell 1. At the same time, the inner side of the door panel 302 presses the outer wall of the pad 7 tightly. Then, the third bolt 304 passes through the vertical plate 303 from the outside to the inside and is connected to the round thread of the outer wall of the outer shell 1 to complete the fixing of the door panel 302. Then, the rear flange of the first straight pipe 4 is connected and fixed to the flange of the gas compressor pipeline. Subsequently, the flange of the second straight pipe 5 is fixed to the flange of the exhaust pipe, and the flange in front of the curved pipe 6 is fixed to the flange at the end of the water pipe.

[0028] The operation of the heat exchanger in a gas compressor:

[0029] The hot gas generated during the operation of the gas compressor enters the outer casing 1 through the first straight pipe 4. At this time, the water source in the water pipe enters through the upper part of the front end of the curved pipe 6, and the water source fills the interior of the curved pipe 6. Then, the high temperature gas inside the outer casing 1 will transfer heat through the curved pipe 6 to contact the water source, causing the water source to heat up. Subsequently, the water source is discharged below the front end of the curved pipe 6. Then, the flue gas will enter the exhaust pipe through the second straight pipe 5 to complete the heat exchanger operation.

[0030] Replacement of heat exchanger support for gas compressor:

[0031] After the first bracket 201 and the second bracket 202 are cracked and damaged, the third bolt 304 is rotated outward through the vertical plate 303 to disengage from the outer wall opening of the outer shell 1. Then, the handle 8 is grasped and the door panel 302 is pulled outward to disengage from the outer wall opening of the outer shell 1 along with the frame 301. Next, the first bolt 203 is rotated outward through the second bracket 202 to disengage from the first bracket 201. Then, the first bracket 201 is removed from the outer shell 1. Subsequently, the second bolt 205 is rotated upward through the square plate 204 to disengage from the bottom of the inner wall of the outer shell 1. Then, the second bracket 202 is removed from the outer shell 1. Then, the new first bracket 201 and the second bracket 202 are installed. The above operations are performed to replace the support of the internal pipes of the heat exchanger.
