Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, in particular to a heat pipe heat exchanger with a multi-stage heat exchange function. Background Art

[0002] The heat pipe in the heat pipe heat exchanger is a heat transfer component with high thermal conductivity. The heat pipe transfers heat by evaporating and condensing the working fluid in a fully enclosed vacuum tube shell. It has a series of advantages such as extremely high thermal conductivity, good isothermal properties, the heat transfer area on both sides of the hot and cold sides can be arbitrarily changed, long-distance heat transfer can be achieved, and temperature can be controlled.

[0003] A large amount of heat is generated in the flue gas emissions from boiler production or in the hot water emissions from factories. Direct emission will result in energy waste, so a heat pipe heat exchanger is used to recycle the heat in the emissions. The multi-stage heat exchange function can achieve gradual heating of the refrigerant, which is more economical in the use of heat energy and improves the conversion rate of heat energy. When the refrigerant is liquid, the debris in the water flow will flow through the heat pipe heat exchanger with multi-stage heat exchange function under the influence of the water flow, polluting the environment inside the heat pipe heat exchanger. Long-term use will cause pipe blockage. As the temperature rises, scale will be generated in the water. The water flow can react with ion exchange resin to remove the corresponding particles in the water flow, thereby purifying the water flow and reducing the generation of scale. However, ion exchange resin has a certain service life and needs to be replaced regularly. During the replacement process, the machine needs to be shut down to disassemble and disassemble the ion exchange resin for processing, which makes it inconvenient to use. Summary of the Invention

Water flow will not directly impact the interior of the first air outlet 36 and the air inlet 34.

[0049] The first self-processing mechanism, the second self-processing mechanism and the third processing mechanism have the same structure. The first self-processing mechanism includes a rotating box 50, an opening 1 51, an opening 2 52 and a groove 53. The rotating box 50 is located on the outer wall of the pipe 7, and the two are connected. Opening 1 51 and opening 2 52 are respectively provided at both ends of the rotating box 50. The opening 2 52 is located at the end of the rotating box 50 away from the pipe 7. The side wall of the rotating box 50 is provided with a groove 53, and the groove 53 is connected to the pipe 7. A rotating shaft 54 ​​is provided in the rotating box 50, and a driving block 55 is fixed to the outer wall of the rotating shaft 54. The driving block 55 includes a concave section a and a convex section b connected alternately. The rotating shaft 54 ​​extends to the inner wall of the groove 53.

[0050] A threaded sealing cover 56 is provided at the second opening 52 of the first self-processing mechanism, a feed hopper 57 is provided at the second opening 52 of the second self-processing mechanism, and the rotating shaft 54 ​​of the first self-processing mechanism is rotatably connected to the power shaft 1 20 through a belt 1.

[0051] The concave section a is in contact with the inner wall of the rotary box 50 , and the arc-shaped groove 23 is provided on the rotation path of the concave section a.

[0052] The power mechanism includes an isolation net 60, a second power shaft 61, a second power impeller 62, a second belt 63 and a third belt 64. The isolation net 60 is fixedly arranged on the inner wall of the pipeline 7. A second power shaft 61 is rotatably provided at the center of the isolation net 60. Both ends of the second power shaft 61 extend to the outside of the isolation net 60. A second power impeller 62 is provided at one end of the second power shaft 61 close to the secondary refrigerant inlet 5.

[0053] The second power shaft 61 is connected to the rotating shaft 54 ​​of the second self-processing mechanism through a second belt 63 , and the second power shaft 61 is connected to the rotating shaft 54 ​​of the third self-processing mechanism through a third belt 64 . A control valve is provided on the pipeline 7 .

[0054] The specific implementation method is as follows: when in use, heat medium 1 flows through the first-level heat medium inlet 3, the first-level heat pipe heat exchanger body 1 and the first-level heat medium outlet, and heat medium 2 flows through the second-level heat medium inlet 6, the second-level heat pipe heat exchanger body 2 and the second-level heat medium outlet. The valve is opened, and the refrigerant flows through the first-level refrigerant inlet, the first-level heat pipe heat exchanger body 1, the first-level refrigerant outlet 4, the pipeline 7, the second-level refrigerant inlet 5, the second-level refrigerant inlet 5 and the second-level refrigerant outlet. The medium temperature at the first-level heat medium inlet 3 is lower than the medium temperature at the second-level heat medium inlet 6, completing the heat exchange process.

[0055] During the flow through pipe 7:

[0056] Step S1, the cleaning mechanism is in a static state, the bottom end of the second bolt 42 extends out of the second threaded hole 40 and rests on the side wall of the V-shaped cleaning tube 33, the second bolt 42 limits the V-shaped cleaning tube 33, the air inlet 34 points to the ground, and the air outlet 36 obliquely points to the ground; the water flows through the filter 21 to drive the power impeller 24 to rotate, and the impurities in the water flow will remain on the outside of the filter 21. The power impeller 24 drives the power shaft 20 and the filter 21 to rotate synchronously, and the debris accumulated on the filter 21 encounters the cleaning After the block 22, some of the debris will be scraped off and left at the cleaning block 22. The power shaft 1 20 also drives the belt 1, the rotating shaft 54 ​​of the third self-processing mechanism and the driving block 55 to rotate synchronously. The concave section a can drive the debris on its rotation path to rotate synchronously, thereby driving the debris to the opening 2 52 of the first self-processing mechanism. After a period of use, the debris becomes more and the sealing cover 56 can be removed to open the opening 2 52 so that the debris can be discharged to the outside. The convex section b is tightly connected to the inner wall of the rotating box 50 to prevent water from overflowing.

[0057] Step S2, water flows through the isolation net 60 to drive the power impeller 2 62 to rotate. The power impeller 2 62 drives the power shaft 2 61 to rotate. Similarly, the power shaft 2 61 drives the second self-processing mechanism and the third self-processing mechanism to operate through the belt 2 63 and the belt 3 64 respectively. The feed hopper 57 is filled with clean ion exchange resin. When the concave section a opens upward, the ion exchange resin falls into the concave section a of the second self-processing mechanism. When the concave section a opens downward, this part of the ion exchange resin falls into the processing chamber 8. The second self-processing mechanism continues to put clean ion exchange resin into the processing chamber 8; similarly, the third self-processing mechanism continues to take the contaminated ion exchange resin in the processing chamber 8 out of the processing chamber 8, and the contaminated ion exchange resin is discharged to the outside through the opening 2 52 of the third self-processing mechanism.

[0058] The filter 21 can be cleaned regularly or continuously. The process of cleaning the filter 21 is as follows:

[0059] The second bolt 42 is turned upward, and the bottom end of the second bolt 42 is located above the pipe 7. The elastic force of the torsion spring drives the second connecting shaft 31 and the V-shaped cleaning tube 33 to rotate upward, so that when the cleaning mechanism is in the cleaning state, the inner wall of the connecting seat 30 limits the V-shaped cleaning tube 33, the air inlet hole 34 is aligned with the threaded hole 1 39, and the air outlet 1 36 is aligned with the filter 21. The bolt 1 41 is removed. The external compressed air output pipe is made of non-deformable material. The output pipe is inserted into the threaded hole 1 39 and the air inlet hole 34, and then the air flow is blown in. After passing through the air inlet hole 34 and the V-shaped cleaning tube 33, the air flow is discharged outward from the air outlet 1 36 and the second air outlet 37. The air outlet 1 36 blows air toward the filter 21, and then back-blows the filter 21. The air outlet 2 37 blows air toward the wind shield 25, and then drives the filter 21 to rotate through the wind shield 25. The rotation direction of the filter 21 is referenced Figure 9 When the filter 21 rotates, debris accumulated on the filter 21 encounters the cleaning block 22, which scrapes off the debris and leaves it in the arc-shaped groove 23. The arc-shaped groove 23 is set on the rotation path of the concave section a. When the driving block 55 of the first self-processing mechanism rotates, it takes away the debris in the arc-shaped groove 23, completing the cleaning. During use, the state of the V-shaped cleaning pipe 33 can be adjusted, and the cleaning operation of the filter 21 can be controlled by controlling the start and stop of the external compressed air. When water flows through the pipe 7, it can promote the reaction between the water flow and the ion exchange resin, thereby purifying the water flow. After the water flow enters the higher temperature secondary heat pipe heat exchanger body 2, the generation of scale is reduced. Under the impact of water flow, the ion exchange resin in the processing chamber 8 tends to move from left to right. The ion exchange resin at the rightmost end of the processing chamber 8 is replaced, and the clean ion exchange resin is replenished at the leftmost end of the processing chamber 8. In this way, the ion exchange resin in the processing chamber 8 is continuously replaced during the flow of water, and there is no need to stop the machine to replace the disassembled ion exchange resin, thereby improving the convenience of equipment use.

[0060] When there is water flowing through the pipe 7 or when there is no water flowing through, the filter screen 21 can be driven to rotate, and the debris on the surface of the filter screen 21 can be gathered in front of the arc groove 23. Only when there is no water flowing through the pipe 7 can the debris in front of the arc groove 23 fall by its own gravity, and the falling is not thorough, and the cleaning is not thorough. Through the cooperation of the concave section a and the convex section b of the driving block 55, the debris in front of the arc groove 23 can be scraped off the cleaning block 22 and the pipe 7. The concave section a contains a mixture of debris and water, so that when the opening of the concave section a is downward, the debris can be more thoroughly separated from the concave section a under the action of water, and can be cleaned without disassembling the filter screen 21, thereby improving the cleaning efficiency of the debris.
