Description

Technical Field

[0001] The present invention relates to the technical field of combustion heating equipment, in particular to a heat exchange device of combustion heating equipment. Background Art

[0002] The heat exchange device of combustion heating equipment is the core component for transferring heat energy from fuel combustion to the medium. Its design directly affects heating efficiency and safety. It can be divided into two categories according to the heat exchange medium: one is the air heat exchange type, such as metal fire tubes, finned heat exchangers, and plate-type air heat exchangers. It directly exchanges heat with the air through convection and radiation of high-temperature flue gas. It has a simple or compact structure and a thermal efficiency ranging from 50% to 90%, which is suitable for equipment such as heaters. The other type is the water or thermal oil heat exchange type, including water tube, fire tube, and condensing heat exchangers. It indirectly provides heat by heating water or thermal oil. Condensing heat exchangers use the latent heat of water vapor and have a thermal efficiency of up to 105%. They require a water circulation system. Key design elements include the selection of high-temperature resistant, corrosion-resistant, and thermally conductive materials, the use of fins, turbulent flow design, and multi-return structure to enhance heat transfer, and focus on sealing, explosion protection, temperature control and other safety designs to ensure efficient and safe heating. They are widely used in scenarios such as household wall-mounted boilers and industrial boilers.

[0003] In the existing technical field, the exhaust gas temperature generated during the combustion process of traditional combustion heating equipment is usually as high as 600℃ to 1000℃, but the existing design does not have an efficient heat exchange device, resulting in a large amount of heat energy carried by the exhaust gas being directly discharged into the atmosphere, and thus the heat energy of the combustion exhaust gas cannot be effectively recovered, which not only causes energy waste and cost increase, but also increases the environmental burden.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the fan, the exhaust gas of the combustion heating equipment is used as a high-temperature fluid to enter the plate heat exchanger plate from the top interface of the fixed compression plate. The low-temperature fluid in the low-temperature fluid supply equipment enters the plate heat exchanger plate from the bottom flange of the fixed compression plate. The high-temperature fluid and the low-temperature fluid enter the flow channel between the plates of the plate heat exchanger through the corner holes inside the plate heat exchanger to complete the heat exchange. The high-temperature fluid passes through the connecting hose from the bottom interface and enters the inside of the cylinder shell. The third electric telescopic rod drives the rod to move backward or forward in the inner cavity of the slot seat by its own extension and contraction, so that the rod can cooperate with the connecting hose. Drive one end of the second connection to move forward or backward, and with the cooperation of multiple second connections, drive the first connecting rod at the corresponding position to drive the rotating seat to rotate inside the guide shell, so that the multiple rotating seats drive the baffles at their corresponding positions to rotate, and then adjust the angle of the baffle on the outside of the guide shell. The airflow inside the cylindrical shell hits the surface of the baffle along the outer wall of the guide shell, thereby achieving a blocking effect on the fluid inside the cylindrical shell, thereby extending the overall residence time of the high-temperature fluid inside the plate heat exchange mechanism and reducing heat loss. The remaining exhaust gas enters the exhaust pipe through the connecting valve pipe and is discharged to the outside of the external exhaust gas treatment device through the exhaust pipe.

[0017] 2. The electric telescopic rod drives the movable pressing plate to move backward along the guide beam and the fixed frame through its own extension, so that the movable pressing plate and the fixed pressing plate release the pressing and fixing state of the plate heat exchanger plates. The second electric telescopic rods on both sides drive the mounting frame to drive the clamping module to move to the designated position outside the adjacent plate heat exchanger plates. The clamping module clamps the plate heat exchanger plates at the corresponding position and separates the two adjacent plate heat exchanger plates with the cooperation of the second electric telescopic rod and the clamping module. The moving component extends the cleaning execution component into the two side plates. At the inner side of the plate of the plate heat exchanger, the fifth motor drives the third gear to rotate, so that the arc-shaped toothed rack rotates to a specified angle position under the action of the rotational force of the third gear and the limiting action of the rollers in the upper and lower limit roller assemblies, so that the cleaning brush extends into the inner cavity of the corrugated groove in the plate heat exchanger plate. The vibration motor vibrates the cleaning brush by itself with the cooperation of the connecting spring, so that the cleaning brush scrapes off the debris in the inner cavity of the corrugated groove in the plate heat exchanger plate. The vacuum cleaner, with the cooperation of the dust collecting hopper, sucks the debris into its own interior for centralized processing.

[0018] In summary, the present invention utilizes the exhaust gas of the combustion equipment as a heat source for heat exchange operations, and prolongs the residence time of the heat source in the heat exchanger, effectively reducing heat energy loss. The heat exchange device not only improves the utilization rate of the heat energy of the combustion exhaust gas, but also ensures the long-term stable operation of the plate heat exchanger, reducing maintenance costs and energy consumption.

[0036] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific operation is as follows:

[0037] Step 1: The staff connects the fan 7 inlet to the exhaust port of the combustion heating equipment, connects the low-temperature fluid supply equipment to the upper and lower pipe flanges 24 respectively, and controls the control box 1 to start the fan 7 and the third electric telescopic rod 36. The fan 7 uses the exhaust gas of the combustion heating equipment as a high-temperature fluid to enter the plate heat exchanger plate 27 through the top interface 23 of the fixed pressure plate 22. The low-temperature fluid in the low-temperature fluid supply equipment enters the plate heat exchanger plate 27 through the bottom pipe flange 24 of the fixed pressure plate 22. The warm fluid and the low-temperature fluid enter the flow channel between the plates of the plate heat exchanger 27 through the internal plate corner holes respectively, forming turbulence. When the high-temperature fluid flows through one side of the plate heat exchanger plate 27, the heat is transferred to the metal wall of the plate heat exchanger plate 27 by convection heat transfer. The heat is transferred to the low-temperature fluid on the other side by heat conduction through the metal wall of the plate heat exchanger plate 27. The heat is absorbed by convection heat transfer to complete the heat exchange between the cold and hot fluids. After the heat exchange is completed, the low-temperature fluid is discharged from the top flange 24, and the high-temperature fluid The third electric telescopic rod 36 passes through the connecting hose 32 from the bottom interface 23 and enters the interior of the cylindrical shell 31. The third electric telescopic rod 36 drives the plug rod 39 to move backward or forward in the inner cavity of the slot seat 38 by its own extension and contraction, so that the plug rod 39 drives one end of the second connection 314 to move forward or backward under the cooperation of the connecting hose 32. Under the cooperation of multiple second connections 314, the first connecting rod 313 at the corresponding position drives the rotating seat 310 to rotate inside the guide shell 37, so that the multiple rotating seats 310 drive themselves to The baffle 311 is rotated clockwise or counterclockwise to adjust the angle of the baffle 311 on the outside of the guide shell 37. The airflow inside the cylindrical shell 31 hits the surface of the baffle 311 along the outer wall of the guide shell 37, thereby blocking the fluid inside the cylindrical shell 31 and inducing turbulence, thereby extending the overall residence time of the high-temperature fluid inside the plate heat exchange mechanism 2 and reducing heat loss. The remaining exhaust gas enters the exhaust pipe 34 through the connecting valve pipe 33 and is discharged to the outside exhaust gas treatment device through the exhaust pipe 34.

[0038] Step 2: After the heat exchange operation is completed, the staff controls the control box 1 to start the electric telescopic rod 28. The electric telescopic rod 28 drives the movable pressing plate 26 to move backward along the guide beam 25 and the fixed frame 21 through its own extension, so that the movable pressing plate 26 and the fixed pressing plate 22 release the pressing and fixing state of the plate heat exchanger plate 27. The staff moves the cleaning mechanism 4 to the specified position outside the plate heat exchange mechanism 2 and controls the controller 43 to start. The preset program inside the controller 43 controls the second electric telescopic rod 44, the clamping module 46, the first motor 54, the second motor 58, the fourth motor 520 and the third motor 512 to start. The second electric telescopic rods 44 on both sides extend and shorten to drive the mounting frame 45 to drive the clamping module 46 to move to the specified position outside the adjacent plate heat exchanger plates 27. The clamping module 46 clamps the plate heat exchanger plates 27 at the corresponding position and separates the two adjacent plate heat exchanger plates 27 with the cooperation of the second electric telescopic rod 44 and the clamping module 46. The motor 54 drives the top pulley in the first belt assembly 53 to rotate the belt to drive the first mounting frame 55 to rise or fall along the outside of the guide rail rod 52 to a specified height position. The second motor 58 drives the right pulley in the second belt assembly 57 to rotate the belt to drive the second mounting frame 59 to move horizontally in the left and right directions to a specified position under the limiting action of the first guide rail assembly 56. The fourth motor 520 drives the second gear 521 to rotate, so that the second gear 521 moves along the second rack 522, and drives the mounting plate 519 to move the mounting frame 51 in the front and rear directions to a specified position under the limiting action of the second guide rail assembly 518. The third motor 512 drives the first gear 513 to rotate, so that the first rack 516 drives the moving frame 514 under the action of the rotational force of the first gear 513. The moving frame 514 extends from the inner cavity of the insert sleeve housing 511 to a specified length position under the limiting action of the limiting assembly 515, thereby allowing the cleaning execution component 6 to extend to the inner side of the plate heat exchanger plates 27 on both sides.

[0039] Step 3: The preset program inside the controller 43 controls the fifth motor 63, the vibration motor 69 and the vacuum cleaner 42 to start. The fifth motor 63 drives the third gear 64 to rotate, so that the arc-shaped toothed rack 65 rotates clockwise or counterclockwise to a specified angle position under the action of the rotational force of the third gear 64 and the limiting action of the rollers in the upper and lower limit roller assemblies 62, thereby allowing the cleaning brush 67 to extend into the inner cavity of the corrugated groove in the plate heat exchanger plate 27. The vibration motor 69 vibrates itself to make the cleaning brush 67 vibrate with the cooperation of the connecting spring 68, so that the cleaning brush 67 scrapes off the debris in the inner cavity of the corrugated groove in the plate heat exchanger plate 27. The vacuum cleaner 42, with the cooperation of the dust collecting hopper 66, sucks the debris into its own interior for centralized processing.
