Description

Technical Field

[0001] This application relates to the field of waste treatment technology, specifically to an electromagnetic heating heat transfer oil circulation energy-saving device for degradation equipment. Background Technology

[0002] The efficient resource utilization of organic solid waste depends on providing and maintaining a stable and suitable high-temperature environment for its internal microbial community.

[0003] Currently, the most commonly used heating technology in the industry is resistance wire heating, which generates Joule heat by passing an electric current through a resistance element, and then indirectly transfers it to the main body of the degradation equipment via heat transfer oil. This technology has the following inherent defects: First, the thermal efficiency is low, usually only about 60%, with significant energy loss during the multi-stage transfer process from the resistance wire to the heat transfer oil and then to the equipment; second, the temperature control accuracy is poor. Due to the large thermal inertia of the resistance wire itself, the system response is lagging, resulting in a temperature control deviation that is usually between 5℃ and 10℃, which is difficult to meet the requirements of microorganisms for high-temperature environments; in addition, the resistance wire is prone to aging and breakage when working at high temperatures for a long time, posing safety hazards, and the maintenance and replacement costs are high.

[0004] To address some of the aforementioned issues, existing Chinese patents (CN213052050U) on the heating system and equipment for food waste degradation have introduced improved solutions that utilize electromagnetic heating principles combined with circulating pumps. These solutions heat flowing heat transfer oil through electromagnetic induction and then transfer heat through forced circulation. While these solutions have made some progress in improving heating efficiency and safety, they primarily focus on structural replacement and optimization. Their control logic is typically quite simple, often only possessing basic start / stop or power adjustment functions. They lack intelligent control strategies that match the complex biochemical process of organic solid waste degradation and still have the following shortcomings. First, it fails to integrate advanced control algorithms (such as PID control), making it impossible to achieve high-precision (such as ±1℃) real-time temperature closed-loop control, which makes it difficult to overcome system thermal inertia and results in large temperature fluctuations. Second, it only targets the single variable of temperature and fails to monitor and adjust other key parameters reflecting the state of the material (such as humidity). Third, when treating organic solid waste, it cannot adaptively adjust heating and ventilation according to different stages of the degradation process. Therefore, existing heating technologies for organic solid waste degradation equipment, whether traditional resistance heating or improved electromagnetic heating, still have prominent problems such as low level of intelligence and insufficient control precision at the control level, resulting in high energy consumption, poor process stability, and large fluctuations in the final treatment effect. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the purpose of this application is to provide an electromagnetic heating heat transfer oil circulation energy-saving device for degradation equipment.

[0006] The electromagnetic heating heat transfer oil circulation energy-saving device for degradation equipment described in this application includes an electromagnetic heating coil group, the electromagnetic heating coil group is fixedly connected to the organic solid waste degradation equipment, and a heat transfer oil layer is fixedly connected to the lower part of the main body of the organic solid waste degradation equipment. The base of the organic solid waste degradation equipment is connected to a heat transfer oil conveying assembly. The heat transfer oil conveying assembly is connected to the heat transfer oil layer and the electromagnetic heating coil group, and is used to drive the heat transfer oil to circulate between the two. The heat transfer oil conveying assembly includes a first heat transfer oil layer pipe and a second heat transfer oil layer pipe for distributing and conveying the heated heat transfer oil to the heat transfer oil layer. The organic solid waste degradation equipment is also equipped with a cylinder temperature sensor for monitoring the temperature of the fermentation material and an oil temperature sensor for monitoring the temperature of the heat transfer oil. A maintenance door is installed on the main body of the organic solid waste degradation equipment, and a central control system and touchscreen are fixedly connected to the maintenance door. A humidity sensor is also fixedly connected to the organic solid waste degradation equipment. The central control system and touchscreen are configured to perform the following controls: based on a built-in PID control algorithm, dynamically adjust the power of the electromagnetic heating coil group according to the deviation between the cylinder temperature sensor, the oil temperature sensor, and the set temperature, maintaining the oil temperature control accuracy within ±1℃; and based on the material moisture content data monitored by the humidity sensor, adjust the heating strategy of the electromagnetic heating coil group in a coordinated manner.

[0007] Furthermore, it is particularly preferred that the heat transfer oil conveying assembly also includes a hot oil pump motor fixedly connected to the base of the organic solid waste degradation equipment. The output shaft of the hot oil pump motor is connected to the circulating pump through a coupling protective cover and a pump shaft. The circulating pump is provided with a heat transfer oil return outlet and a heat transfer oil return inlet. The heat transfer oil return inlet of the circulating pump is connected to the heat transfer oil layer through a heat transfer oil return pipe equipped with a shut-off valve. The heat transfer oil return outlet of the circulating pump is provided with a bellows, a vertical check valve, and an electromagnetic heating tube in sequence. One end of the electromagnetic heating tube is connected to the oil inlet of the electromagnetic heating coil group.

[0008] Furthermore, it is particularly preferred that a pressure gauge for monitoring the system's circulating pressure is fixedly connected to the electromagnetic heating tube.

[0009] Furthermore, it is particularly preferred that the heat-conducting oil layer is covered with an insulation layer.

[0010] Furthermore, it is particularly preferred that the heat-conducting oil layer has an exhaust port to balance the internal and external pressures.

[0011] Furthermore, it is particularly preferred that a camera is fixedly connected to the organic solid waste degradation equipment, and a camera display screen is installed on the maintenance door, with the camera's viewing angle facing the inner cavity of the equipment.

[0012] Furthermore, it is particularly preferred that the maintenance door has a heat dissipation vent.

[0013] The electromagnetic heating heat transfer oil circulation energy-saving device for degradation equipment described in this application has the following advantages: A. This invention generates a high-speed alternating magnetic field in an electromagnetic heating coil assembly using high-frequency current. According to the law of electromagnetic induction, this magnetic field induces eddy currents inside the electromagnetic heating coil assembly. These eddy currents, under the action of metal resistance, directly convert electrical energy into heat energy, thereby causing the electromagnetic heating coil assembly itself to heat up rapidly and uniformly. Subsequently, the heat-conducting oil flowing through the interior of the electromagnetic heating coil assembly absorbs heat efficiently through direct contact with the coil assembly wall, causing the temperature to rise rapidly. This process does not require intermediate media such as resistance wires, achieving a direct and efficient (efficiency >95%) conversion of electrical energy to heat energy, reducing energy transfer losses, and achieving energy savings of 30%-70% compared to ordinary electric heating methods.

[0014] B. This invention also achieves this by continuously receiving real-time data from the cylinder temperature sensor (monitoring the temperature of fermentation materials), the oil temperature sensor (monitoring the temperature of the heat transfer oil), and the humidity sensor (monitoring the moisture content of the materials) throughout the entire operation process. Combined with the system's built-in PID (Proportional-Integral-Derivative) control algorithm, this algorithm collects the material temperature monitored by the cylinder temperature sensor and the heat transfer oil temperature monitored by the oil temperature sensor in real time, and dynamically compares and calculates them with the set values. Specifically, the proportional (P) stage responds quickly to current temperature deviations, instantly adjusting the power output of the electromagnetic heating coil group; the integral (I) stage accumulates historical deviations, completely eliminating steady-state errors and ensuring that the temperature remains stable at the set value without overshoot; and the derivative (D) stage predicts temperature change trends, suppressing system thermal inertia fluctuations in advance. Through the synergistic effect of these three components, the system successfully stabilizes the oil temperature control accuracy within the heat transfer oil layer within ±1℃, providing an extremely stable temperature environment for microorganisms. Meanwhile, when the humidity sensor detects a change in the material's moisture content, for example, when the moisture content drops below 30%, insufficient moisture will cause microbial activity to decrease and enter a dormant state. At this time, even maintaining a suitable heating temperature will not promote the continuous and efficient degradation of microorganisms. In this case, the central control system will automatically reduce the power output of the electromagnetic heating coil group to reduce unnecessary heat and electricity consumption, thereby achieving energy efficiency optimization. In this way, the central control system can intelligently link and adjust the heating strategy (such as modifying the temperature setpoint and other stirring, ventilation, and other parameters), realizing the coordinated intelligent management of temperature and humidity parameters, thereby achieving the effect of energy saving and emission reduction.

[0015] C. This invention also constructs a highly efficient closed-loop path of "low-temperature oil entering the heating zone to absorb heat - high-temperature oil being sent to the heat-using equipment to release heat - cooling oil returning" through forced circulation driven by a circulating pump. This breaks the traditional non-circulating pump system that relies on natural convection heat transfer from the oil, resulting in a "near-hot and far-cold" stratification phenomenon. In addition, the high-speed flowing oil can continuously flush the inner wall of the heat-conducting oil layer, peeling off any thermal resistance layer that may form, thus significantly improving the system's heating efficiency, making the temperature distribution more uniform, avoiding accelerated aging and damage to the equipment due to local overheating, and effectively extending the service life of the equipment.

[0016] D. The present invention also rapidly heats the heat transfer oil through the above-mentioned electromagnetic heating coil group, with a thermal efficiency of over 95%, which can save 30%-70% energy compared with the traditional electric heating method. Combined with forced circulation technology to accelerate the uniform temperature of the oil, the system can enter the low power heat preservation mode more quickly, and the full power operation time is greatly reduced. At the same time, it eliminates the ineffective energy consumption caused by local overheating, and achieves significant energy saving at the system level. Attached Figure Description

Example 1

[0021] An energy-saving device for electromagnetic heating and heat transfer oil circulation in degradation equipment, such as Figure 1-3 As shown, it includes an electromagnetic heating coil group 10, which is fixedly connected to the organic solid waste degradation device, and a heat-conducting oil layer 16 is fixedly connected to the lower part of the main body of the organic solid waste degradation device. A heat transfer oil conveying assembly is connected to the base of the organic solid waste degradation equipment. The heat transfer oil conveying assembly is connected to the heat transfer oil layer 16 and the electromagnetic heating coil group 10, and is used to drive the heat transfer oil to circulate between the two. The heat transfer oil conveying assembly includes a first heat transfer oil layer pipe 11A and a second heat transfer oil layer pipe 11B that distribute and convey the heated heat transfer oil to the heat transfer oil layer 16. The organic solid waste degradation equipment is also equipped with a cylinder temperature sensor 14 for monitoring the temperature of fermentation materials and an oil temperature sensor 15 for monitoring the temperature of heat transfer oil. The main body of the organic solid waste degradation equipment is equipped with a maintenance door 22, on which a central control system and a touch screen 21 are fixedly connected. A humidity sensor 18 is fixedly connected to the organic solid waste degradation equipment. The central control system and touch screen 21 are configured to perform the following controls: based on the built-in PID control algorithm, according to the deviation between the cylinder temperature sensor 14, the oil temperature sensor 15 and the set temperature, the power of the electromagnetic heating coil group 10 is dynamically adjusted to maintain the oil temperature control accuracy within ±1℃; and based on the material moisture content data monitored by the humidity sensor 18, the heating strategy of the electromagnetic heating coil group 10 is adjusted in linkage.

[0022] The heat transfer oil conveying assembly also includes a hot oil pump motor 1 fixedly connected to the base of the organic solid waste degradation equipment. The output shaft of the hot oil pump motor 1 is connected to the circulating pump through a coupling protective cover and a pump shaft 2. The circulating pump is provided with a heat transfer oil return outlet 3 and a heat transfer oil return inlet 4. The heat transfer oil return inlet 4 of the circulating pump is connected to the heat transfer oil layer 16 through a heat transfer oil return pipe 12 equipped with a shut-off valve 5. The heat transfer oil return outlet 3 of the circulating pump is provided with a bellows 6, a vertical check valve 7 and an electromagnetic heating tube 8 in sequence. One end of the electromagnetic heating tube 8 is connected to the oil inlet of the electromagnetic heating coil group.

[0023] A pressure gauge 9 for monitoring the system's circulating pressure is fixedly connected to the electromagnetic heating tube 8.

[0024] The heat-conducting oil layer 16 is covered with an insulation layer 17.

[0025] An exhaust port 13 is provided on the heat-conducting oil layer 16 to balance the internal and external pressure.

[0026] A camera 19 is fixedly connected to the organic solid waste degradation equipment, and a camera display screen 20 is installed on the maintenance door 22. The camera 19 faces the inner cavity of the equipment.

[0027] A ventilation opening 23 is provided on the maintenance door 22.

[0028] When using the electromagnetic heating and heat transfer oil circulation energy-saving device of this organic solid waste degradation equipment, firstly, the operator sets the required target temperature through the central control system and touch screen 21 fixed on the maintenance door 22. Then, the hot oil pump motor 1 fixed on the base is started. The oil pump motor 1 drives the circulation pump to start running through the coupling protective cover and pump shaft 2, and then the heat transfer oil return inlet 4 of the circulation pump generates suction. At the same time, the suction force continuously extracts the heat transfer oil from the heat transfer oil layer 16 through the heat transfer oil return pipe 12 equipped with the shut-off valve 5. The extracted low-temperature heat transfer oil then flows through the heat transfer oil return pipe 12 in sequence. In the return pipe, the shut-off valve 5 is used to regulate or cut off the flow rate. The low-temperature heat transfer oil then enters the circulation pump through the heat transfer oil return inlet 4. After being pressurized in the circulation pump, it is pumped out from the heat transfer oil return outlet 3. Next, the pressurized heat transfer oil flows through the bellows 6 and the vertical check valve 7 to prevent backflow, then through the electromagnetic heating tube 8 and is delivered to the electromagnetic heating coil assembly 10. According to the set program, the central control system and touchscreen 21 output ordinary AC power (50 / 60Hz) to the electromagnetic heating coil assembly 10, which is then rectified by a circuit to convert it into DC power. This DC power is further converted into high-frequency AC power (5-35kHz). This high-frequency current generates a high-speed alternating magnetic field in the electromagnetic heating coil assembly 10. Based on the law of electromagnetic induction, this magnetic field causes the electromagnetic heating coil assembly... Eddy currents are generated inside the electromagnetic heating coil assembly 10. Under the action of the metal resistance, the eddy currents directly convert electrical energy into heat energy, thereby causing the electromagnetic heating coil assembly 10 to heat up rapidly and evenly. Then, the heat-conducting oil flowing through the inside of the electromagnetic heating coil assembly 10 absorbs heat efficiently through direct contact with the wall of the electromagnetic heating coil assembly 10, and the temperature rises rapidly. This process does not require intermediate media such as resistance wires, and realizes a direct and efficient (efficiency >95%) conversion of electrical energy to heat energy, reducing the loss in the energy transfer process. Compared with ordinary electric heating methods, it can achieve an energy saving effect of 30%-70%. Subsequently, the heated high-temperature heat transfer oil flows out from the oil outlet inside the electromagnetic heating coil group 10. To achieve uniform heating, the heat transfer oil flow is divided into two: one path enters the first heat transfer oil layer pipe 11A, and the other path enters the second heat transfer oil layer pipe 11B. These two oil pipes transport the high-temperature heat transfer oil back to different areas of the heat transfer oil layer 16 in parallel. Since the heat transfer oil layer 16 is usually located outside the bioreactor of the organic solid waste degradation equipment, the heat of the high-temperature heat transfer oil will be stably and uniformly conducted to the organic solid waste material in the cylinder through the wall during its flow. This provides and maintains the required precise high-temperature environment for the reproduction and degradation of aerobic microorganisms. The cylinder temperature sensor 14 then monitors the temperature of the material and feeds the information back to the central control system and touch screen 21. Meanwhile, in order to monitor the status of materials inside the tank in real time (such as fermentation level and space utilization), the internal images captured by the camera 19 can be transmitted to the camera display screen 20 through the camera 19 settings. This allows operators to achieve visual monitoring of the production process without turning on the equipment, enhancing the intuitiveness and convenience of operators in monitoring the status of materials inside the tank. It should be noted that during the entire operation, the central control system and touch screen 21 continuously receive real-time data from cylinder temperature sensor 14 (monitoring the temperature of fermentation materials), oil temperature sensor 15 (monitoring the temperature of heat transfer oil), and humidity sensor 18 (monitoring the moisture content of materials). In conjunction with the system's built-in PID (proportional-integral-derivative) control algorithm, the algorithm collects the material temperature monitored by cylinder temperature sensor 14 and the heat transfer oil temperature monitored by oil temperature sensor 15 in real time, and performs dynamic comparison and calculation with the set value. During system debugging and operation, the PID control algorithm adopts the following parameter tuning and optimization strategy to achieve the best control effect: First, in the initial parameter setting stage, the integral (Ki=0) and derivative actions (Kd=0) are turned off, and the proportional coefficient Kp is gradually increased. The temperature response curve is observed until the system temperature shows a critical constant amplitude oscillation, and the proportional coefficient at this time is recorded as Kp0. Then, Kp=0.4~0.6Kp0 is taken as the working value of the proportional coefficient to ensure that the system has sufficient response speed while avoiding excessive overshoot. Next, gradually add the integral term and slowly increase the integral coefficient Ki, observe the effect of the system on eliminating steady-state error until the temperature stabilizes near the set value and there is no obvious overshoot. Generally, Ki = 0.01~0.1Kp is taken to eliminate the accumulated deviation without causing system oscillation. Then, gradually add the differential element and slowly increase the differential coefficient Kd to observe the system's ability to suppress temperature fluctuations until the temperature disturbance is quickly and smoothly suppressed. Generally, Kd = 0.1~0.5Kp is taken to predict and offset the hysteresis effect caused by the system's thermal inertia in advance. Finally, the parameters are fine-tuned according to the selected improved algorithm (such as integral separation algorithm, variable parameter PID, Smith predictor, etc.). By adjusting the integral separation threshold β, segmented control parameters, or establishing a prediction model, the ideal control effect of no overshoot or overshoot <5%, steady-state error <±1℃, and no continuous oscillation is finally achieved. Thus, through precise tuning and optimization of the aforementioned PID parameters, the central control system can achieve rapid response and accurate compensation, effectively overcoming system thermal inertia and stabilizing the heat transfer oil temperature within an extremely narrow range of ±1℃, providing an extremely stable temperature environment for microorganisms. Simultaneously, when the humidity sensor 18 detects a change in the material's moisture content—for example, when the moisture content drops below 30%—insufficient moisture will cause reduced microbial activity and a dormant state. At this point, even maintaining a suitable heating temperature will not promote continuous and efficient microbial degradation. In this situation, the central control system will automatically reduce the power output of the electromagnetic heating coil group 10, reducing unnecessary heat and electricity consumption, thereby optimizing energy efficiency. Thus, the central control system can intelligently adjust the heating strategy (such as modifying the temperature setpoint and other stirring, ventilation, and other parameters), achieving coordinated intelligent management of temperature and humidity parameters, thereby achieving energy saving and emission reduction. Meanwhile, in the above... After the high-temperature heat transfer oil in the heat transfer oil layer 16 releases heat, the temperature of the heat transfer oil drops and it becomes "low-temperature oil" again. At this time, the hot oil pump motor 1 continues to work, extracting the cooled heat transfer oil again and entering the next cycle. In this way, the heat transfer oil continuously circulates in the closed loop of "electromagnetic heating coil group 10 → heat transfer oil layer 16 → circulation pump → electromagnetic heating coil group 10", forming the core path of forced circulation heating. Thus, through the forced circulation driven by the circulation pump, a highly efficient closed loop path of "low-temperature oil enters the heating zone to absorb heat - high-temperature oil is sent to the heat-using equipment to release heat - cooled oil returns" is constructed. This breaks the traditional non-circulation pump system that relies on the natural convection heat transfer of the oil body and has the stratification phenomenon of "near heat and far cold". In addition, the high-speed flowing oil body can also continuously flush the inner wall of the stainless steel container and the heat-using equipment, peel off the thermal resistance layer that may be formed, so that the system heating efficiency is significantly improved, the temperature distribution is more uniform, and the equipment is prevented from aging and being damaged due to local overheating, effectively extending the service life of the equipment. Meanwhile, the insulation layer 17 covering the outside of the heat-conducting oil layer 16 further reduces heat loss, and the pressure gauge 9 fixed on the first heat-conducting oil layer pipe 11A is used to monitor the system pressure. The exhaust port 13 set at the high point of the system ensures that the heat-conducting oil layer 16 balances the internal and external air pressure, ensuring heat transfer efficiency and operational safety. The heat dissipation port 23 opened on the maintenance door 22 helps the electrical control cabinet dissipate heat. Thus, by using electromagnetic heating to make the container self-heat, the thermal efficiency can reach over 95%, saving 30%-70% more energy than traditional electric heating methods. Combined with forced circulation technology to accelerate the uniform temperature of the oil, the system can enter the low-power heat preservation mode more quickly, significantly reducing the full-power operation time. At the same time, it eliminates the ineffective energy consumption caused by local overheating, achieving significant energy saving at the system level.
