Description

Technical Field

[0001] The 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 changed arbitrarily, heat transfer over long distances, and temperature control.

[0003] A large amount of heat is generated in the flue gas emissions produced by boilers or in the hot water emissions of factories. Direct emissions will cause energy waste, so heat pipe heat exchangers are used to recycle heat in emissions. The multi-stage heat exchange function can achieve gradual heating of the refrigerant, which saves more thermal energy and improves the conversion rate of thermal 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 drive 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 resins have a certain service life and need to be replaced regularly. During the replacement process, the ion exchange resin needs to be disassembled and processed, which makes it inconvenient to use. Summary of the invention

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 fixedly provided on the outer wall of the rotating shaft 54.

[0024] A threaded sealing cover 56 is provided at the opening 52 of the first self-processing mechanism, a feeding hopper 57 is provided at the 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 20 through a belt 1.

[0025] The concave section a is in contact with the inner wall of the rotating box 50 , and the arc groove 23 is arranged on the rotating path of the concave section a.

[0026] The power mechanism includes an isolation net 60, a power shaft 61, a power impeller 62, a belt 63 and a belt 64. The isolation net 60 is fixedly arranged on the inner wall of the pipeline 7. A power shaft 61 is rotatably provided at the center of the isolation net 60. Both ends of the power shaft 61 extend to the outside of the isolation net 60. A power impeller 62 is provided at one end of the power shaft 61 close to the secondary refrigerant inlet 5.

[0027] 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 .

[0028] The specific implementation method is as follows: when in use, heat medium 1 flows through the primary heat medium inlet 3, the primary heat pipe heat exchanger body 1 and the primary heat medium outlet, heat medium 2 flows through the secondary heat medium inlet 6, the secondary heat pipe heat exchanger body 2 and the secondary heat medium outlet, the valve is opened, and the refrigerant flows through the primary refrigerant inlet, the primary heat pipe heat exchanger body 1, the primary refrigerant outlet 4, the pipeline 7, the secondary refrigerant inlet 5, the secondary refrigerant inlet 5 and the secondary refrigerant outlet, the medium temperature at the primary heat medium inlet 3 is lower than the medium temperature at the secondary heat medium inlet 6, and the heat exchange process is completed; During the flow through pipe 7: Step S1, the cleaning mechanism is in a static state, the bottom end of the second bolt 42 extends out of the threaded hole 40 and abuts against 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 points obliquely 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, and 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 is reached, the debris will be scraped off and left at the cleaning block 22. The power shaft 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 rotating 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 is 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. Step S2, water flows through the isolation net 60 to drive the power impeller 2 62 to rotate, and 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 away from 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.

[0029] The filter 21 may be cleaned regularly or continuously. The process of cleaning the filter 21 is as follows: 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 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, and the output pipe of the external compressed air is made of a non-deformable material. The output pipe is inserted into the threaded hole 1 39 and the air inlet 34, and then the air flow is blown in. After passing through the air inlet 34 and the V-shaped cleaning tube 33, the air flow is discharged outwardly 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 blows back 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 refers to Fig. 9When the filter 21 rotates, the debris accumulated on the filter 21 encounters the cleaning block 22, and the debris will be scraped off and left at the arc groove 23. The arc groove 23 is set on the rotation path of the concave section a. The driving block 55 of the first self-processing mechanism takes away the debris at the arc groove 23 when it rotates, completing the cleaning. When in use, the state of the V-shaped cleaning pipe 33 can also be not 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 pipeline 7, it can promote the reaction between the water flow and the ion exchange resin, thereby purifying the water flow, and reducing the generation of scale after the water flow enters the secondary heat pipe heat exchanger body 2 with a higher temperature. 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, thereby continuously replacing the ion exchange resin in the processing chamber 8 during the passage of water. There is no need to stop the machine to replace the disassembled ion exchange resin, thereby improving the convenience of equipment use.

[0030] When there is water flowing through the pipe 7 or not, 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 down by its own gravity, and the falling and cleaning are 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 has 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 the filter screen 21 can be cleaned without disassembling it, thereby improving the cleaning efficiency of the debris.

[0031] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
