Description

Technical Field

[0001] The present disclosure relates to the field of chemical technology, and more specifically, to a device for continuously regenerating waste clay. Background Art

[0002] Bleaching clay is a natural or synthetic substance with high adsorption properties, primarily used to remove impurities during the refining process of petroleum products such as paraffin wax, Fischer-Tropsch wax, and lubricant base oils. It captures harmful substances in oil products through physical adsorption, thereby improving the purity and stability of the products. Bleaching clay plays a vital role in the petroleum refining process, effectively removing pigments, oxidation products, and other harmful compounds from oil products, making the finished product clearer and more transparent with better performance. However, after use, bleaching clay absorbs large amounts of oil substances, becoming waste bleaching clay. Direct discharge or landfill of waste bleaching clay can cause environmental pollution, especially potential contamination of soil and groundwater. Therefore, waste bleaching clay needs to be recycled and reused. However, existing regenerated bleaching clay equipment is complex, difficult to operate, and expensive, making continuous production impossible, reducing production efficiency and resulting in resource waste.

[0035] The present disclosure provides a waste clay continuous regeneration device, comprising a rotary kiln, a screw machine, a collecting tank, a cyclone separator and a gas-liquid separator, wherein the two ends of the rotary kiln are respectively denoted as a first end and a second end, the vertical height of the first end of the rotary kiln from the ground is greater than the vertical height of the second end of the rotary kiln from the ground; the screw machine is connected to the first end of the rotary kiln, and a feed port is provided on the screw machine, the waste clay enters the screw machine from the feed port and is transported to the discharge position of the rotary kiln via the screw machine; a collecting tank is provided at the second end of the rotary kiln, a discharge port is provided at the bottom of the collecting tank, and a blower is provided at the top of the collecting tank, and the blower passes the reaction gas into the rotary kiln; the cyclone separator is connected to the rotary kiln and is close to the first end of the rotary kiln; the gas-liquid separator is connected to the cyclone separator.

[0036] The waste clay continuous regeneration device provided by the present disclosure is easy to operate, low in cost, and can operate continuously, thereby effectively improving production efficiency and economic benefits.

[0037] For ease of understanding, refer to Figures 1 to 2 , the specific structure and working principle of the waste clay continuous regeneration device disclosed in the present invention are explained in detail with reference to an embodiment.

[0038] like Figure 1 As shown, the present disclosure provides a continuous regeneration device for waste clay, comprising a rotary kiln 1, a screw machine 2, a collecting tank 4, a cyclone separator 7 and a gas-liquid separator 8, wherein the two ends of the rotary kiln 1 are respectively recorded as a first end and a second end, and the vertical height of the first end of the rotary kiln 1 from the ground is greater than the vertical height of the second end of the rotary kiln 1 from the ground; the screw machine 2 is connected to the first end of the rotary kiln 1, and a feed port 3 is provided on the screw machine 2, and the waste clay enters the screw machine 2 from the feed port 3 and is transported to the discharge position of the rotary kiln 1 via the screw machine 2; a collecting tank 4 is provided at the second end of the rotary kiln 1, a discharge port 5 is provided at the bottom of the collecting tank 4, and a blower 6 is provided at the top of the collecting tank 4, and the blower 6 passes the reaction gas into the rotary kiln 1; the cyclone separator 7 is connected to the rotary kiln 1 and is close to the first end of the rotary kiln 1; the gas-liquid separator 8 is connected to the cyclone separator 7.

[0039] Specifically, the two ends of the rotary kiln 1 are designated as the first end and the second end, respectively. The first end is at a greater vertical height from the ground than the second end, meaning that the rotary kiln 1 is tilted relative to the ground. During operation, the rotary kiln 1 rotates, and the tilt facilitates the movement of waste clay from the first end to the second end. A sealing device is provided between the first and second ends of the rotary kiln 1 to prevent external air from entering the interior of the rotary kiln 1. This sealing device isolates the interior of the rotary kiln 1 from the outside world, preventing uncontrolled ingress of external air. This helps maintain a stable temperature and undisturbed gas composition within the rotary kiln 1, thereby ensuring a smooth regeneration process and improving regeneration efficiency. This not only ensures controllable internal environment within the rotary kiln 1 but also enhances system safety and energy efficiency by preventing air leakage. In addition, a wear-resistant lining is provided on the inner wall of the rotary kiln 1 to protect the inner wall of the rotary kiln 1 from wear and corrosion caused by the materials during the processing process, thereby ensuring that the rotary kiln 1 can operate stably for a long time. This not only enhances the durability of the rotary kiln 1, but also improves the economic benefits of the entire system by reducing maintenance frequency and lowering operating costs.

[0040] like Figure 2 As shown, one end of the screw machine 2 is connected to one end of the rotary kiln 1, and the other end is connected to a motor 24. A feed port 3 is provided above the end of the screw machine 2 near the motor 24. Waste clay enters the screw machine 2 from above the feed port 3. Driven by the motor 24, the screw machine 2 transports the waste clay to the discharge position inside the rotary kiln 1. Furthermore, the motor 24 of the screw machine 2 has a speed regulation function, which allows the speed of the screw machine 2 to be flexibly adjusted according to the characteristics of the processed material and the requirements of the regeneration process, ensuring efficient material transportation and mixing within the rotary kiln 1. Furthermore, the screw blades of the screw machine 2 are made of high-temperature resistant material, maintaining good mechanical properties and stability even in high-temperature environments, thereby ensuring reliable operation of the entire system and improving regeneration efficiency.

[0041] like Figure 1 As shown, a collection tank 4 is provided at the second end of the rotary kiln 1. The rotary kiln 1 is connected to the middle of the collection tank 4. A blower 6 is connected to the top of the rotary kiln 1, and a discharge port 5 is provided at the bottom. The blower 6 is used to introduce reaction gases into the rotary kiln 1. The collection tank 4 is used to collect the regenerated clay, which is then discharged through the discharge port 5. A cyclone separator 7 is connected to the top of the rotary kiln 1 and is located near the first end of the rotary kiln 1. It is used to separate solid particles and gases generated during the regeneration process. A gas-liquid separator 8 is connected to the cyclone separator 7 and is used to separate liquid from the gas.

[0042] The working process of the waste clay continuous regeneration device provided in the present disclosure is as follows:

[0043] First, the waste clay enters the screw machine 2 through the feed port 3, is transported to the first end of the rotary kiln 1 by the screw machine 2, and is specifically transported to the discharge position at the first end. Afterwards, the waste clay moves inside the rotary kiln 1 in the direction from the first end to the second end of the rotary kiln 1, and in the process of movement, the adsorbed organic matter and other impurities are separated, that is, the waste clay undergoes a regeneration reaction. During the regeneration of the waste clay, the blower 6 introduces the reaction gas required for regeneration into the rotary kiln 1, which can be air or an inert gas such as nitrogen, to promote the entire regeneration process. The regenerated clay enters the collection tank 4 and is discharged from the discharge port 5 of the collection tank 4 under the action of gravity. A valve is provided at the discharge port 5 to flexibly control the discharge of the regenerated clay, thereby facilitating the centralized collection of the regenerated clay. The gas generated during the regeneration process is first separated by a cyclone separator 7 to separate solid particles and other impurities in the gas. The separated gas then enters a gas-liquid separator 8 to further separate the liquid from the gas, thereby avoiding environmental pollution caused by the exhaust gas generated by regeneration.

[0044] The waste clay continuous regeneration device provided by the present disclosure is simple to operate, so that the waste clay can be efficiently regenerated. Moreover, due to the adoption of a continuous operation mode, the production efficiency can be significantly improved and the regeneration cost can be reduced.

[0045] In one embodiment of the present disclosure, a crushing device and a screening device are connected before the feed port 3, both for crushing and screening the waste clay.

[0046] Specifically, the crushing device first crushes the waste clay into smaller particles to increase its surface area, which is beneficial to the subsequent processing process. After that, the screening device screens the crushed waste clay according to a predetermined particle size range to ensure that the particle size of the material entering the subsequent processing steps is uniform, thereby improving processing efficiency and product quality. It not only ensures the consistency of the raw materials, but also improves the processing capacity and separation effect of the entire system through crushing and screening.

[0047] Since the regeneration process of the waste clay needs to be carried out under high temperature conditions, in one embodiment of the present disclosure, a heating jacket 23 is provided on the outer wall of the rotary kiln 1 , and the heating jacket 23 is configured to provide a heat source for the rotary kiln 1 .

[0048] like Figure 2As shown, the outer wall of the rotary kiln 1 is equipped with a heating jacket 23, specifically an electric heating jacket 23. This jacket 23 provides heat to the interior of the rotary kiln 1, ensuring that the entire regeneration process is carried out at an appropriate temperature. In this embodiment, the operating principle of the heating jacket 23 is based on resistive heating: when current passes through a heating element made of a high-resistivity material (such as iron-chromium-aluminum alloy wire or nickel-chromium alloy wire), heat energy is generated according to Joule's law. To ensure temperature control during the heating process, the electric heating jacket 23 is typically equipped with a temperature control system that automatically adjusts the current according to a preset temperature. In addition, to improve heating efficiency and ensure safety, the heating jacket 23 is wrapped with multiple layers of insulating material to reduce heat loss. During installation, ensure that the heating jacket 23 is firmly attached to the outer wall of the rotary kiln 1 to ensure even heat distribution. Regular maintenance and inspection are also crucial to maintaining the heating jacket 23 in good condition. An efficient and safe electric heating jacket 23 not only ensures that the internal temperature of the rotary kiln 1 reaches ideal regeneration conditions, but also reduces energy consumption and operating costs.

[0049] In one embodiment of the present disclosure, a spray gun 9 and a temperature measuring thermocouple 10 are provided in the rotary kiln 1 , and the spray gun 9 and the temperature measuring thermocouple 10 are fixed to a bracket 11 in the rotary kiln 1 through a spray gun sleeve and a thermocouple sleeve.

[0050] Specifically, if Figure 2 As shown, brackets 11 are installed inside the rotary kiln 1 and are evenly distributed throughout the kiln 1. A temperature-measuring thermocouple 10 is fixed to the center of the rotary kiln 1 via brackets 11 and extends from the first end to the second end of the rotary kiln 1. The temperature-measuring thermocouple 10 uses the difference in thermoelectromotive force generated by two thermocouple wires composed of different metal materials when the temperature changes. This difference can be detected by a circuit connected to an external measuring instrument and converted into a temperature reading, allowing real-time monitoring of temperature changes within the rotary kiln 1. The operator can adjust other parameters based on the temperature data provided by the temperature-measuring thermocouple 10 to ensure that the regeneration reaction proceeds at an appropriate temperature. To prevent excessive temperatures within the rotary kiln 1 from affecting the regeneration reaction, a spray gun 9 is also installed within the rotary kiln 1. In this embodiment, the spray gun 9 is a water spray gun that sprays water into the rotary kiln 1, thereby lowering the temperature within the rotary kiln 1. Fixing the spray gun 9 and the temperature measuring thermocouple 10 on the bracket 11 through the sleeve can ensure that these components are stably installed inside the rotary kiln 1 and can withstand working conditions in a high temperature environment. It can also facilitate maintenance and replacement of these components, ensuring long-term stable operation of the equipment.

[0051] In one embodiment of the present disclosure, a cooling jacket 12 is provided on the outer wall of the screw machine 2 , and a gap is provided between the cooling jacket 12 and the outer wall of the screw machine 2 , and the gap is configured to accommodate a cooling medium.

[0052] Specifically, since the temperature of the upstream device of the waste clay is generally high, the temperature of the waste clay entering the feed port 3 will be higher than the temperature required for regeneration. Therefore, the waste clay needs to be cooled before entering the rotary kiln 1. Figure 2 As shown, a cooling jacket 12 is installed on the outer wall of the screw extruder 2. A gap is defined between the cooling jacket 12 and the outer wall of the screw extruder 2. By injecting a cooling medium (such as water or other coolant) into the gap, the waste clay can be effectively cooled. The cooling jacket 12 ensures that the cooling medium is evenly distributed throughout the outer wall of the screw extruder 2, effectively removing heat and maintaining the internal temperature of the screw extruder 2 within a suitable range. This helps ensure that the waste clay regeneration performance is not affected by excessive temperatures during transportation. Furthermore, the cooling jacket 12 protects the screw extruder 2 from damage caused by high temperatures, thereby extending the service life of the equipment.

[0053] In one embodiment of the present disclosure, a first baffle 13 is provided at one end of the screw machine 2 communicating with the rotary kiln 1 . The first baffle 13 is a streamlined structure and is located above the blanking position of the rotary kiln 1 .

[0054] Specifically, after the screw machine 2 transports the waste clay to the drop position, more dust will splash upward and directly enter the cyclone separator 7, reducing the regeneration efficiency of the waste clay. Figure 2 As shown, a first baffle 13 is required at the end where the screw conveyor 2 connects to the rotary kiln 1. The first baffle 13 is configured as a streamlined structure. The streamlined first baffle 13 helps guide the waste clay from the screw conveyor 2 to the rotary kiln 1 for a smooth transition, ensuring that the material can enter the rotary kiln 1 smoothly. Furthermore, because the first baffle 13 is located above the material drop location, it acts as a barrier, reducing the splashing of dust when it enters the rotary kiln 1, helping to maintain the cleanliness and stable operation of the system. Therefore, the first baffle 13 not only helps improve the efficiency and reliability of material transportation, but also ensures uniform material distribution during the regeneration process, thereby improving the overall performance of the regeneration device.

[0055] In one embodiment of the present disclosure, the waste clay continuous regeneration device further includes a second baffle 22, which is located at the center of the rotary kiln 1 and close to the second end of the rotary kiln 1, extending from the second end to the inner cavity of the collection tank 4, and the area of the second baffle 22 is larger than the cross-sectional area of the collection tank 4.

[0056] Specifically, if Figure 2As shown, the second baffle 22 is fixed to the bracket 11 inside the rotary kiln 1 and extends from the first end to the second end of the rotary kiln 1. The second baffle 22 is located in the center of the rotary kiln 1, near the second end, and extends from the second end into the inner cavity of the collection tank 4. This helps guide the regenerated clay into the collection tank 4, ensuring smooth discharge from the discharge port 5. Because the area of the second baffle 22 is larger than the cross-sectional area of the collection tank 4, it effectively reduces dust generated when the regenerated clay enters the collection tank 4, thereby helping to maintain a clean system. Furthermore, since the blower 6 is installed at the top of the collection tank 4, if the second baffle 22 were not installed, some of the gas introduced by the blower 6 might be directly discharged from the discharge port 5 under pressure, resulting in a waste of resources. The second baffle 22, however, blocks and guides the reaction gas introduced from the blower 6, preventing waste of resources and improving the efficiency of the regeneration reaction.

[0057] In one embodiment of the present disclosure, a vibration device is installed on the inner wall of the collection tank 4 to prevent the regenerated clay from adhering to the tank wall. Specifically, the vibration device effectively prevents the regenerated clay from adhering to the tank wall, ensuring that the clay flows smoothly into the collection tank 4. This also helps improve collection efficiency and reduces cleaning and maintenance workload, thereby improving overall production efficiency and economic benefits.

[0058] In one embodiment of the present disclosure, the blower 6 is connected to the collection tank 4 through an air duct 20 , and a filter 21 is provided in the air duct 20 .

[0059] Specifically, the blower 6 provides the necessary airflow power for the rotary kiln 1, which helps to promote the regeneration process inside the rotary kiln 1. Figure 2 As shown, the filter 21 in the air duct 20 can filter out particulate matter from the airflow, preventing impurities from entering the interior of the rotary kiln 1, thereby protecting the equipment from damage and ensuring the purity of the regeneration process. The clean airflow filtered by the filter 21 helps improve the efficiency and quality of the regeneration process, ensuring that the regenerated clay meets the required purity standards, and helping to improve the performance and efficiency of the entire waste clay continuous regeneration device.

[0060] In one embodiment of the present disclosure, a filter 14 is provided between the cyclone separator 7 and the rotary kiln 1 , and one end of the filter 14 is connected to the rotary kiln 1 , and the other end of the filter 14 is connected to the cyclone separator 7 .

[0061] Specifically, if Figure 2As shown, in this embodiment, a two-stage Y-type filter 14 is provided before the cyclone separator 7. The purpose of designing the Y-type filter 14 is to pre-remove larger particles in the exhaust gas of the rotary kiln 1, thereby reducing the load of the subsequent cyclone separator 7 and improving the overall separation efficiency. The working principle of the Y-type filter 14 is based on the filter screen 21 or filter element inside it. These filter elements can capture and block solid particles in the airflow, allowing the cleaned gas to continue to flow. By pre-filtration, larger particles can be effectively prevented from entering the cyclone separator 7, reducing the wear on the internal components of the cyclone separator 7, thereby extending the service life of the equipment.

[0062] The use of the Y-type filter 14 also helps improve the separation efficiency of the subsequent cyclone separator 7, ensuring more effective separation of fine particles in the gas. This is because after the gas passes through the Y-type filter 14, larger particles are removed, leaving the cyclone separator 7 to process only smaller particles. This not only reduces the separation difficulty but also improves separation accuracy. Furthermore, because the Y-type filter 14 captures most large particles, particle collisions within the cyclone separator 7 are reduced, energy consumption is reduced, and separation efficiency is improved.

[0063] By pre-installing the filter 14, not only can the stable operation of the gas purification system be ensured, but the processing capacity and efficiency of the entire system can also be significantly improved. This double filtration method not only simplifies the process, but also ensures that the quality of the final exhaust gas meets the standards, which contributes to environmental protection and resource recovery.

[0064] In one embodiment of the present disclosure, the cyclone separator 7 is a jacketed cyclone separator 7. Specifically, after the two-stage Y-type filter 14, a two-stage jacketed cyclone separator 7 is provided. A jacket is provided between the outer shell and the inner cylinder of the jacketed cyclone separator 7. The jacket can be used to introduce a heating medium or a cooling medium to control the temperature inside the separator. After the gas enters the separator, a high-speed rotating airflow is formed inside the jacketed cyclone separator 7. The centrifugal force generated by the rotating airflow pushes the heavier particles to the inner wall of the separator, and then the particles slide down along the wall and are collected. By controlling the temperature, the jacketed cyclone separator 7 can provide a more stable temperature environment, which helps to improve the separation efficiency. A valve is provided at the bottom of the cyclone separator 7 and is connected to a collection device, so that the operator can flexibly control the collection of the separated materials and recycle the collected materials, thereby realizing the effective recycling of resources and embodying the principles of environmental protection and economy.

[0065] In one embodiment of the present disclosure, the gas-liquid separator 8 includes a heat exchanger, a refrigerant inlet, a refrigerant outlet, and a particle bed disposed at the bottom of the gas-liquid separator 8 .

[0066] Specifically, the gas-liquid separator 8 is used to separate the gas-liquid mixture, wherein the heat exchanger regulates the internal temperature through the circulation of the refrigerant to ensure that the gas-liquid separation is carried out at the appropriate temperature conditions. The refrigerant enters the heat exchanger through the refrigerant inlet, completes the heat exchange internally, and then leaves through the refrigerant outlet. A granular bed is provided at the bottom of the gas-liquid separator 8. The granular bed can further promote the condensation and separation of the liquid, and can also capture and adsorb tiny particles in the airflow, thereby improving the separation efficiency and purity, thereby improving the stability and reliability of the entire system.

[0067] In one embodiment of the present disclosure, the waste clay continuous regeneration device further includes an absorption tank 15 , and the lower portion of the absorption tank 15 is connected to the top of the gas-liquid separator 8 .

[0068] Specifically, if Figure 2 As shown, the gas separated from the top of gas-liquid separator 8 enters the lower portion of absorption tank 15. Absorption tank 15 is used to further purify the gas from gas-liquid separator 8, ensuring that the discharged gas is cleaner and reducing its impact on the environment. Absorption tank 15 also absorbs harmful components in the gas, such as volatile organic compounds (VOCs) and other pollutants, ensuring that emissions meet environmental standards. This further purification reduces the content of harmful substances in the gas, improving the operational safety of the entire system.

[0069] In one embodiment of the present disclosure, a spraying device is provided within the absorption tank 15 for spraying an absorbent to improve the absorption efficiency of harmful gases. Specifically, the absorption tank 15 is equipped with a spraying device. By spraying the absorbent, the absorption efficiency of harmful gases can be effectively improved, ensuring that the harmful gases are fully absorbed and converted into harmless substances. This not only improves the ability to treat harmful gases, but also enhances the environmental performance and safety of the entire system by optimizing the absorption process.

[0070] In one embodiment of the present disclosure, the waste clay continuous regeneration device also includes an induced draft fan 16 and an exhaust gas combustion device 17, wherein the induced draft fan 16 is connected to the absorption tank 15, and an exhaust gas detection device is provided at the output end of the induced draft fan 16; the output end of the induced draft fan 16 is provided with a first exhaust gas pipe 18 and a second exhaust gas pipe 19, wherein the second exhaust gas pipe 19 is connected to the input end of the exhaust gas combustion device 17.

[0071] Specifically, if Figure 2As shown, an induced draft fan 16 is connected to the absorption tank 15 and is used to extract the gas after being purified by the absorption tank 15. An exhaust gas detection device is installed at the output end of the induced draft fan 16 to monitor the concentration of pollutants in the gas and ensure that the emissions meet environmental standards. Two exhaust gas pipes are installed at the output end of the induced draft fan 16: a first exhaust gas pipe 18 and a second exhaust gas pipe 19. The gas in the first exhaust gas pipe 18 is qualified gas detected by the exhaust gas detection device and is discharged directly into the atmosphere through the first exhaust gas pipe 18. The gas in the second exhaust gas pipe 19 is unqualified gas detected by the exhaust gas detection device and is connected to the input end of the exhaust gas combustion device 17. The exhaust gas combustion device 17 is used to further treat the unqualified exhaust gas, converting harmful components into harmless substances through high-temperature combustion. The exhaust gas combustion device 17 ensures that harmful components in the exhaust gas are completely decomposed, improving the cleanliness of the exhaust gas. The exhaust gas detection device monitors the concentration of pollutants in the gas to ensure that the emissions meet environmental regulations and ensure environmental safety.

[0072] The waste clay continuous regeneration device provided by the present disclosure is easy to operate, low in cost, and can operate continuously, thereby effectively improving production efficiency and economic benefits.
