Description

Technical Field

[0001] The present invention relates to the technical field of combustion heating equipment, and particularly to a heat exchange device for a combustion heating equipment. Background Technique

[0002] The heat exchange device of a combustion heating equipment is the core component for realizing the transfer of the heat energy generated by fuel combustion to a medium. Its design directly affects the heating efficiency and safety. According to the heat exchange medium, it can be divided into two categories: one is the air heat exchange type, such as metal fire tubes, finned heat exchangers and plate air heat exchangers, which directly conduct convective and radiative heat exchange between high-temperature flue gas and air, with a simple or compact structure, and the thermal efficiency ranges from 50% to 90%, being applicable to equipment such as warm air heaters; the other is the water or heat-conducting oil heat exchange type, including water tube type, fire tube type and condensing heat exchangers, which indirectly supply heat by heating water or heat-conducting oil. Among them, the condensing heat exchanger utilizes the latent heat of water vapor, and the thermal efficiency can reach 105%. A water circulation system needs to be configured. The key design elements include selecting materials with high temperature resistance, corrosion resistance and good thermal conductivity, adopting fin, turbulent flow design, multi-pass structure to strengthen heat exchange, and paying attention to sealing, explosion prevention, temperature control and other safety designs to ensure efficient and safe heating, and being widely used in scenarios such as domestic wall-mounted boilers and industrial boilers; In the existing technical field, the temperature of the waste gas generated during the combustion process of traditional combustion heating equipment is usually as high as 600°C to 1000°C. However, the existing design does not provide an efficient heat exchange device, resulting in a large amount of heat energy carried by the waste gas being directly discharged into the atmosphere, and thus the heat energy of the combustion waste gas cannot be effectively recovered, which not only causes energy waste and cost increase, but also aggravates the environmental burden, and there is a lack of effective anti-blocking measures, leading to energy waste and high equipment maintenance costs.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the fan, the exhaust gas of the combustion heating equipment is used as a high-temperature fluid to enter the plate of the plate heat exchanger from the top interface of the fixed compression plate. The low-temperature fluid in the low-temperature fluid supply device enters the plate of the plate heat exchanger from the bottom pipe flange of the fixed compression plate. The high-temperature fluid and the low-temperature fluid enter the flow channel between the plates 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 plug rod to move backward or forward in the inner cavity of the slot seat through its own extension and shortening, so that the plug 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, and the airflow inside the cylinder 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 cylinder shell, thereby extending the overall residence time of the high-temperature fluid inside the plate heat exchange mechanism to reduce heat loss, and 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.

[0015] 2. The electric telescopic rod drives the movable pressing plate to move backward along the guide beam and the fixed frame through its own elongation, so as to release the pressing and fixing state of the plate heat exchanger plates between the movable pressing plate and the fixed pressing plate. The second electric telescopic rods on both sides drive the mounting frame to drive the clamping module to move to the specified positions outside the adjacent two sides of the plate heat exchanger plates. The clamping module clamps the plate heat exchanger plates at the corresponding positions, and separates the adjacent two plate heat exchanger plates under the cooperation of the second electric telescopic rods and the clamping module. The moving component extends the cleaning execution component into the inner positions of the two sides of the plate heat exchanger plates. The fifth motor drives the third gear to rotate, so that the arc-shaped tooth groove frame rotates to the specified angular position under the action of the rotational force of the third gear and the limiting action of the rollers in the upper and lower limiting roller assemblies on both sides. Furthermore, the cleaning brush extends into the inner cavity of the corrugated groove in the plate heat exchanger plate. The vibration motor makes the cleaning brush vibrate itself through its own vibration under the cooperation of the connecting spring, so that the cleaning brush scrapes off the sundries in the inner cavity of the corrugated groove in the plate heat exchanger plate. The vacuum cleaner sucks the sundries into its own interior through the cooperation of the dust collecting hopper and waits for centralized treatment.

[0016] To sum up, the present invention uses the waste gas of the combustion equipment as a heat source for heat exchange operations, prolongs the residence time of the heat source in the heat exchanger, effectively reduces heat energy loss, and while improving the heat energy utilization rate of the combustion waste gas, ensures the long-term stable operation of the plate heat exchanger, and reduces the maintenance cost and energy consumption.

[0026] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process. The specific work is as follows: Step 1: The staff connects the inlet of the fan 7 to the smoke exhaust port of the combustion heating device, connects the low-temperature fluid supply device to the upper and lower connecting 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 takes the waste gas of the combustion heating device as the high-temperature fluid and enters the inside of the plate heat exchanger plates 27 from the top interface 23 of the fixed pressing plate 22. The low-temperature fluid in the low-temperature fluid supply device enters the inside of the plate heat exchanger plates 27 from the bottom connecting pipe flange 24 of the fixed pressing plate 22. The high-temperature fluid and the low-temperature fluid respectively enter the flow channels between their respective plates through the plate orifice holes inside the plate heat exchanger plates 27 to form a turbulent flow. When the high-temperature fluid flows through one side of the plate heat exchanger plates 27, it transfers heat to the metal wall surface of the plate heat exchanger plates 27 through convective heat transfer. The heat is transferred to the low-temperature fluid on the other side through the metal wall surface of the plate heat exchanger plates 27 by heat conduction and absorbs heat through convective heat transfer, completing the heat exchange between the hot and cold fluids. The low-temperature fluid after heat exchange is discharged from the top connecting pipe flange 24, and the high-temperature fluid passes through the connecting hose 32 from the bottom interface 23 and enters the inside of the cylinder housing 31. The third electric telescopic rod 36 drives the insertion rod 39 to move backward or forward in the inner cavity of the slot seat 38 through its own elongation and shortening, so that the insertion rod 39 drives one end of the second connection 314 to move forward or backward in cooperation with the connecting hose 32. With the cooperation of multiple second connections 314, it drives the first connecting rod 313 at the corresponding position to drive the rotating seat 310 to rotate inside the diversion housing 37, so that multiple rotating seats 310 drive the baffle 311 at their corresponding positions to rotate clockwise or counterclockwise, thereby adjusting the angle of the baffle 311 outside the diversion housing 37. The airflow inside the cylinder housing 31 impacts on the surface of the baffle 311 along the outer wall of the diversion housing 37, realizing the blocking effect on the fluid inside the cylinder housing 31, and at the same time triggering a turbulent flow, thereby prolonging the overall residence time of the high-temperature fluid inside the plate heat exchange mechanism 2 and reducing heat loss. The remaining waste gas enters the inside of the smoke exhaust pipe 34 through the connecting valve pipe 33 and is discharged to the inside of the external waste gas treatment device through the smoke exhaust pipe 34; 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 elongation, so that the pressing and fixing state of the plate heat exchanger plates 27 between the movable pressing plate 26 and the fixed pressing plate 22 is released. The staff moves the cleaning mechanism 4 to a 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 start of 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. 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 a specified position outside the adjacent two plate heat exchanger plates 27. The clamping module 46 clamps the plate heat exchanger plates 27 at the corresponding positions, and separates the adjacent two plate heat exchanger plates 27 under the cooperation of the second electric telescopic rod 44 and the clamping module 46. The first motor 54 drives the top pulley in the first belt assembly 53 to drive the belt to rotate to drive the first mounting frame 55 to move up or down 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 drive the belt to rotate 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 back and forth 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 rotational force of the first gear 513. The moving frame 514 extends from the inner cavity of the insertion cylinder housing 511 to a specified length position under the limiting action of the limiting component 515, and further makes the cleaning execution component 6 extend into the inner side positions of the two plate heat exchanger plates 27; Step 3: The preset program inside the controller 43 controls the start of the fifth motor 63, the vibration motor 69, and the vacuum cleaner 42. The fifth motor 63 drives the third gear 64 to rotate, so that the arc-shaped tooth groove frame 65 rotates clockwise or counterclockwise to a specified angular position under the rotational force of the third gear 64 and under the limiting action of the rollers in the upper and lower limiting roller assemblies 62, and further makes the cleaning brush 67 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 itself in cooperation with the connecting spring 68, so that the cleaning brush 67 scrapes the sundries in the inner cavity of the corrugated groove in the plate heat exchanger plate 27. The vacuum cleaner 42 sucks the sundries into its own interior through the cooperation of the dust collecting hopper 66 and waits for centralized treatment.
