[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a segmented reflux tank, as shown in Figures 1-5. The segmented reflux tank includes a reflux tank 1, a spraying mechanism is fixedly connected to the upper surface of the reflux tank 1, a heat recovery mechanism is fixedly connected to one side of the outer surface of the reflux tank 1 through a bracket plate 2, and a blower 3 is fixedly connected to the middle of the bottom of the reflux tank 1.

[0024] The heat recovery mechanism includes a heat exchanger 4, the outer surface of which is fixedly connected to the inner wall of the support plate 2. A conveying end pipe 5 is fixedly connected to the upper surface of the heat exchanger 4, and a recovery plate 6 is fixedly connected to one end of the conveying end pipe 5. A recovery groove is opened on the surface of the recovery plate 6. An output end pipe 7 is fixedly connected to the bottom of the heat exchanger 4, and a control valve 8 is fixedly connected to the outer surface of the output end pipe 7. During petroleum processing, a large amount of waste heat is generated in the reflux tank 1. In order to improve resource utilization, the waste heat is recovered by the heat recovery mechanism. By recovering waste heat, the efficiency of heat energy utilization is optimized, making the production process energy-saving and efficient. By reasonably recovering and regulating heat energy, the temperature in the reflux tank 1 is kept stable, which helps to ensure consistent process conditions and improve product consistency and quality.

[0025] The spraying mechanism includes a water pump 9, the bottom of which is fixedly installed on the upper surface of the return tank 1. The output end of the water pump 9 is fixedly connected to an outlet pipe 10, and the input end of the water pump 9 is fixedly connected to an inlet pipe 11. One end of the outlet pipe 10 is fixedly connected to a spray plate 12. By adding a spraying mechanism inside the return tank 1, the spraying can help to cool or heat the return liquid more evenly, quickly adjust the temperature inside the tank, maintain the stable temperature range required by the process, prevent local overheating or overcooling, and the fine spray can wash away the deposits or scale on the inner surface of the tank, extend the service life of the equipment, and reduce the frequency of cleaning and maintenance costs.

[0026] The inner wall of the spray plate 12 is provided with water outlet holes, and the outer surface of the spray plate 12 is fixedly connected with the connecting pipe 13. When it is necessary to clean the inside of the return tank 1, the water inlet pipe 11 of the water pump 9 is connected to the external water source, the water pump 9 is started, and the water source flows through the spray plate 12. The water source is released from the water outlet holes of the spray plate 12. The spray plate 12 is set into three groups, and the three groups of spray plates 12 are connected through the connecting pipe 13 to circulate the water source, thereby achieving the effect of cleaning the inside of the return tank 1.

[0027] The interior of the reflux tank 1 is divided into upper and lower chambers, with a partition plate 14 fixedly connected in the middle of the two chambers. The reflux tank 1 is divided into two chambers, which can achieve the effect of segmented reflux. Through segmented control, the local utilization or recovery of heat energy can be realized, reducing the overall energy consumption and improving thermal efficiency.

[0028] A heating ring 15 is fixedly connected to the inner wall of the upper chamber inside the reflux tank 1, and a condenser tube 16 is fixedly connected to the inner wall of the lower chamber inside the reflux tank 1. During processing, in order to ensure that the oil temperature is moderate, the temperature inside the reflux tank 1 is balanced by the heating ring 15 and the condenser tube 16. The two chambers inside the reflux tank 1 can be independently regulated, and the temperature difference between different sections can be precisely controlled to adapt to different process requirements and improve product quality and process stability.

[0029] The outer surface of the reflux tank 1 is provided with a groove, and the outer side of the spray plate 12 is embedded in the inside of the groove. The spray plate 12 is embedded in the reflux tank 1 to facilitate better cooling of the internal temperature of the reflux tank 1, regulate the internal temperature of the tank, maintain the stable temperature range required by the process, and prevent local overheating or overcooling.

[0030] Specifically, during oil processing, the oil is processed in the reflux tank 1. During this process, a large amount of waste heat is generated inside the reflux tank 1. The blower 3 is started, and it gently blows air into the reflux tank 1 to facilitate the diversion of the waste heat. The waste heat is recovered from the recovery trough of the recovery plate 6. The heat exchanger 4 is then started, and it draws the waste heat from the recovery plate 6 through the conveying end pipe 5. The heat is processed and converted internally, and then released from the output end pipe 7. When further recovery is needed, a recovery device is connected to the output end pipe 7, and the control valve 8 is activated to open the switch, thus smoothly recovering the waste heat and achieving resource reuse. By rationally recovering and regulating heat energy, maintaining a stable temperature inside the reflux tank 1 helps ensure consistent process conditions and improve product consistency and quality. Subsequently, during processing, to ensure the oil temperature is moderate... The heating ring 15 and condenser 16 even out the temperature inside the reflux tank 1, allowing for independent temperature regulation of the two chambers within the reflux tank 1. This precisely controls the temperature difference between different sections, adapting to various process requirements and improving product quality and process stability. Subsequently, when cleaning the inside of the reflux tank 1 is required, the water pump 9 inlet pipe 11 is connected to an external water source, and the water pump 9 is started to circulate water through the spray plate 12. The water is then released from the outlet holes of the spray plate 12. The spray plate 12 is configured with three sets, which are connected by the connecting pipe 13 to circulate water, thereby achieving the effect of cleaning the inside of the reflux tank 1. In addition, spraying can also help to cool or heat the reflux liquid more evenly, quickly regulate the temperature inside the tank, maintain the stable temperature range required by the process, and prevent local overheating or overcooling.
