Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a waste heat recovery system for rosin production waste gas. Background Technology

[0002] Rosin is a natural resin extracted from pine resin and is widely used in adhesives, paints, inks, electronic soldering and other fields. Rosin production is mainly obtained by distilling pine resin (the secretion of pine trees), which generates high-temperature waste gas (such as steam and volatile organic compounds). Direct emission of these waste gases will waste thermal energy.

[0003] Rosin production waste gas waste heat recovery system can be used to recover waste heat from distillation waste gas. Its core principle is to transfer the heat in the waste gas to cold water or air through heat exchange, converting it into usable thermal energy (such as preheating raw materials or heating), thereby reducing energy consumption and waste gas emissions. However, terpenoids in rosin production waste gas tend to adhere to the heat exchange surface after cooling, which reduces the heat exchange area of ​​the heat exchanger and narrows the airflow channel, resulting in a decrease in gas flow rate, which will significantly reduce the waste heat recovery efficiency.

[0004] Therefore, to address the problem that terpenoids in rosin production waste gas tend to adhere to the heat exchange surface after cooling, thus significantly reducing the waste heat recovery efficiency of the heat exchanger, a rosin production waste gas waste heat recovery system can be designed to solve this problem. Utility Model Content

[0005] In order to overcome the problem that terpenoids in the waste gas generated during rosin production tend to adhere to the heat exchanger surface after cooling, which reduces the heat exchanger area and narrows the airflow channel, thus reducing the gas flow rate and significantly reducing the waste heat recovery efficiency.

[0006] The technical solution of this utility model is as follows: a rosin production waste gas waste heat recovery system, including a heat exchange cylinder; it also includes a water baffle and a water distribution plate. Multiple heat-conducting gas pipes are fixedly connected inside the heat exchange cylinder, and a vibration-conducting support is fixedly connected to the heat-conducting gas pipes. A base is fixedly connected to the lower end of the heat exchange cylinder, and a water baffle that blocks water flow is rotatably connected inside the base. A water collection trough is provided on the outer ring of the water baffle, and the water collection trough is opened at the bottom of the inner side of the base. A valve is installed and connected to the outer side of the water collection trough. A water distribution plate is fixedly connected to the upper end of the heat exchange cylinder, and a water pipe is connected to the upper end of the water distribution plate.

[0007] Preferably, after rotating the water-blocking plate to block the lower end of the chassis, the valve is opened. Then, hot water enters the water-distribution plate through the water pipe connected to the upper end of the water-distribution plate and flows into multiple heat-conducting gas pipes. The hot water dissolves the adhering impurities on the inner wall of the heat-conducting gas pipes. Subsequently, the hot water carries the impurities into the water collection tank and is discharged from the valve.

[0008] Preferably, one side of the water distribution plate is connected to a hot water pipe via a water pipe, and a resistance heater for heating water is installed inside the hot water pipe.

[0009] Preferably, a water pump is connected to one side of the lower end of the hot water pipe, and multiple evenly distributed shielding grooves are provided on the heat exchange cylinder.

[0010] Preferably, the conductive support consists of a main support and an outer support. The main support is located in the middle inside the heat exchange cylinder, and the outer support is fixed to the upper and lower ends of the outer side of the outer support.

[0011] Preferably, multiple ultrasonic transducers that generate high-frequency vibrations are fixedly connected inside the shielding trough, and a fixed cylinder is fixedly connected to the upper end of the water distribution plate.

[0012] Preferably, one side of the fixed cylinder is penetrated by a water pipe connected to the upper end of the water distribution plate, and an exhaust fan is installed at the upper end of the inside of the fixed cylinder to draw up exhaust gas.

[0013] Preferably, the upper end of the curved surface of the heat exchange cylinder is connected to a cold water injection pipe for supplying cold water, and the lower end of the curved surface of the heat exchange cylinder is connected to a cold water discharge pipe for supplying and discharging cold water.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a baffle plate, valve, and water distribution plate, the baffle plate can be rotated to block the lower end of the base, and then the valve can be opened. Hot water then enters the water distribution plate through the water pipe connected to the upper end of the water distribution plate and flows into multiple heat-conducting gas pipes. The hot water dissolves the adhering impurities on the inner wall of the heat-conducting gas pipes. Subsequently, the hot water carries the impurities into the water collection tank and is discharged from the valve. This allows users to use this method regularly to quickly dissolve and discharge the impurities adhering to the waste heat recovery system, thus preventing terpenes in the exhaust gas from adhering to the heat exchange surface after cooling, which would significantly reduce the waste heat recovery efficiency of the heat exchanger.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a rosin production waste heat recovery system, including a heat exchange cylinder 1; it also includes a water baffle 5 and a water distribution plate 8. Multiple heat-conducting gas pipes 2 are fixedly connected inside the heat exchange cylinder 1, and a vibration-conducting support 3 is fixedly connected to each heat-conducting gas pipe 2. A base plate 4 is fixedly connected to the lower end of the heat exchange cylinder 1, and a water baffle 5 is rotatably connected inside the base plate 4 to block water flow. A water collection trough 6 is provided on the outer ring of the water baffle 5, and the water collection trough 6 is located at the bottom of the inner side of the base plate 4. A valve 7 is installed and connected to the outer side of the water collection trough 6. A water distribution plate 8 is fixedly connected to the upper end of the heat exchange cylinder 1, and a water pipe is connected to the upper end of the water distribution plate 8. After rotating the water baffle 5 to block the lower end of the base plate 4, the valve 7 is opened. Then, hot water enters the water distribution plate 8 through the water pipe connected to the upper end of the water distribution plate 8 and flows into the multiple heat-conducting gas pipes 2, so as to transfer the heat-conducting gas through the hot water. The adhering impurities on the inner wall of pipe 2 dissolve, and then the hot water carrying the impurities flows into the water collection tank 6 and is discharged from the valve 7. One side of the water distribution plate 8 is connected to a hot water pipe 9 through a water pipe. A resistance heater 10 is installed in the hot water pipe 9 to heat the water flowing through the hot water pipe 9 to dissolve the impurities. A water pump 11 is connected to one side of the lower end of the hot water pipe 9. Multiple evenly distributed shielding grooves 12 are opened on the heat exchange cylinder 1. The water pump 11 is used to send water into the hot water pipe 9 and the water distribution plate 8. The conduction support 3 consists of a main support 301 and an outer support 302. The main support 301 is located in the middle inside the heat exchange cylinder 1. The outer support 302 is fixed to the upper and lower ends of the outer side of the outer support 302. The conduction support 3 is used to support the heat conduction pipe 2 and also to conduct the vibration generated when the ultrasonic transducer 13 is started to the heat conduction pipe 2.

[0024] Please see Figures 2-5In this embodiment, multiple ultrasonic transducers 13 that generate high-frequency vibrations are fixedly connected in the shielding groove 12. A fixed cylinder 14 is fixedly connected to the upper end of the water distribution plate 8. The ultrasonic transducers 13 can accelerate the removal of impurities in the heat-conducting gas pipe 2 by vibration during the process of hot water dissolving impurities. One side of the fixed cylinder 14 is penetrated by a water pipe connected to the upper end of the water distribution plate 8. An exhaust fan 15 for drawing up exhaust gas is installed inside the upper end of the fixed cylinder 14. The fixed cylinder 14 is used to draw exhaust gas through the heat-conducting gas pipe 2 and flow upward. The upper end of the curved surface of the heat exchange cylinder 1 is connected to a cold water injection pipe 16 for supplying cold water, and the lower end of the curved surface of the heat exchange cylinder 1 is connected to a cold water discharge pipe 17 for supplying water. During waste heat recovery, cold water enters the interior of the heat exchange cylinder 1 from the cold water injection pipe 16 and is discharged from the cold water discharge pipe 17. At the same time, the exhaust gas absorbs heat through the pipe wall of the heat-conducting gas pipe 2.

[0025] During waste heat recovery, the fixed cylinder 14 is used to draw the waste gas through the heat-conducting gas pipe 2 and flow upward, while cold water enters the interior of the heat exchange cylinder 1 from the cold water injection pipe 16 and is discharged from the cold water discharge pipe 17. At the same time, the waste gas absorbs heat through the pipe wall of the heat-conducting gas pipe 2.

[0026] When cleaning the impurities adhering to the inside of the heat-conducting gas pipe 2, rotate the water-blocking plate 5 to block the lower end of the base plate 4, and then open the valve 7. Next, water is sent into the hot water pipe 9 and the water distribution plate 8 by the water pump 11. At the same time, the resistance heater 10 heats the water flowing through the hot water pipe 9 to dissolve the impurities. The hot water enters the water distribution plate 8 through the water pipe connected to the upper end of the water distribution plate 8 and then flows into multiple heat-conducting gas pipes 2 to dissolve the adhering impurities on the inner wall of the heat-conducting gas pipe 2. Then, the hot water carries the impurities into the water collection tank 6 and is discharged from the valve 7.

[0027] At the same time, the ultrasonic transducer 13 can be turned on to accelerate the shedding of impurities in the heat-conducting gas pipe 2 through vibration during the process of dissolving impurities in the hot water. The conductive support 3 supports the heat-conducting gas pipe 2 and transmits the vibration generated by the ultrasonic transducer 13 when it is turned on to the heat-conducting gas pipe 2.

[0028] Through the above steps, by setting up the water-blocking plate 5, valve 7, and water-distributing plate 8, the water-blocking plate 5 can be rotated to block the lower end of the base plate 4, and then the valve 7 can be opened. Then, hot water enters the water-distributing plate 8 through the water pipe connected to the upper end of the water-distributing plate 8 and flows into multiple heat-conducting gas pipes 2. The hot water dissolves the adhering impurities on the inner wall of the heat-conducting gas pipes 2. Then, the hot water carries the impurities into the water collection tank 6 and is discharged from the valve 7. This allows users to use this method regularly to quickly dissolve and discharge the impurities adhering to the waste heat recovery system, so as to avoid the terpenes in the waste gas from adhering to the heat exchange surface after cooling, which would cause a significant reduction in the waste heat recovery efficiency of the heat exchanger.
