Description

Technical Field

[0001] This invention relates to the technical field of waste treatment, and in particular to an adaptive microwave power control method, apparatus, and storage medium. Background Technology

[0002] Radioactive wet waste is generated during the operation and maintenance of nuclear power plants and nuclear facilities. To address the problems of increasing the volume of waste packages, poor long-term stability of waste, and high disposal costs associated with cement solidification processes for treating such waste, microwave barrel drying technology has begun to be applied in wet waste treatment.

[0003] In the engineering application of microwave barrel drying technology, to ensure that the processing capacity of the microwave barrel drying device reaches its maximum, the magnetron continuously applies microwaves to the material at its maximum design power during operation. However, during the microwave drying process, the temperature of wet waste continuously rises and moisture evaporates, causing its moisture content to continuously decrease. The increased temperature and decreased humidity lead to a decrease in the dielectric loss factor of the wet waste, which in turn reduces its absorption power of microwaves. This results in a situation where the power supplied by the magnetron exceeds the absorption power of the wet waste, leading to energy waste.

[0004] In related technologies, there is a problem where the power supplied by the magnetron is greater than the absorption power of the wet waste because the variation in microwave absorption power is not taken into account, resulting in energy waste.

[0005] The above problems urgently need to be addressed. Summary of the Invention

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. In the description of this invention, it should be noted that the term "or" is generally used to include the meaning of "and / or," unless otherwise expressly indicated.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or a magnetic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, in the description of this application, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. In the description of this invention, "a plurality of" means at least two, such as two, three, or more, unless otherwise explicitly specified.

[0021] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] First, to facilitate understanding of the embodiments of the present invention, some terms or nouns involved in the present invention will be explained below: Microwaves are electromagnetic waves with frequencies ranging from 300MHz to 300GHz. They are a shorthand for a limited frequency band of radio waves, with wavelengths typically between 1 millimeter and 1 meter. They can be divided into decimeter waves, centimeter waves, and millimeter waves.

[0023] The heat coefficient of water vaporization usually refers to the latent heat of vaporization of water, which represents the amount of heat required to change a unit mass of water from a liquid state to a gaseous state at a given temperature. Under standard atmospheric pressure, the latent heat of vaporization of water is approximately 2260 kJ / kg (or 40.8 kJ / mol).

[0024] The dielectric loss factor represents the proportion of electrical energy converted into heat energy per unit volume of dielectric per unit time. Under the action of an alternating electric field, there is an angle between the current vector and the voltage vector flowing through the dielectric. This angle is called the dielectric loss angle, and the tangent of the dielectric loss angle is the dielectric loss factor.

[0025] To address the problems existing in the prior art, embodiments of this application provide an adaptive microwave power control method, apparatus, and storage medium.

[0026] Example 1 This embodiment provides an adaptive microwave power control method, such as... Figure 1 As shown, Figure 1 This is a flowchart of an adaptive microwave power control method according to Embodiment 1 of the present invention, the method comprising: Step S102: Obtain the initial data in the microwave barrel during the historical period and the basic data in the microwave barrel during the target period. The historical period is before the target period. The initial data includes at least the first temperature and the first humidity, and the basic data includes at least the second temperature and the second humidity. Optionally, based on initial data from historical periods and baseline data for the target period, the temperature and humidity data of the wet waste inside the microwave oven can be determined. Since temperature and humidity affect the dielectric loss factor of the wet waste, thus affecting its microwave absorption power, the aforementioned initial and baseline data are necessary. Furthermore, because temperature and humidity indirectly affect the microwave absorption power of the wet waste, both the initial and baseline data must include at least temperature and humidity data (the initial data must include at least a first temperature and a first humidity level, and the baseline data must include at least a second temperature and a second humidity level).

[0027] In some preferred embodiments, initial data from the microwave oven during historical time periods and basic data from the microwave oven during a target time period are acquired. The initial data includes at least a first temperature and a first humidity, and the basic data includes at least a second temperature and a second humidity. This includes: acquiring a first liquid level, mass, first volume, and first temperature from the microwave oven during historical time periods; determining a first humidity based on the mass, first volume, and first liquid level; acquiring a second liquid level and a second temperature from the microwave oven during the target time period; determining the difference between the second liquid level and the first liquid level as a liquid level difference; and determining the second humidity based on the liquid level difference, the first humidity, and the mass.

[0028] Optionally, temperature data can be obtained using a temperature sensor, while humidity data is obtained by measuring the liquid level in the microwave oven using a liquid level sensor, thereby determining the humidity inside the microwave oven based on the liquid level. Specifically, the second humidity is calculated by multiplying the mass of the first water by the mass of the first water, calculating the change in water mass due to evaporation based on the liquid level difference, subtracting the first water mass from the change in water mass, and then dividing this by the water mass without considering humidity changes to obtain the second humidity.

[0029] Specifically, the second humidity level is calculated as follows: in, The second humidity level, t For a moment in history, t + t For the target time period, M t The first humidity level, H t This is the first liquid level height. This is the second liquid level height. m t For quality, ρ The density of water, r Let be the radius of the microwave barrel.

[0030] Optionally, based on the above method, the first temperature and first humidity of the historical period can be obtained, and the second temperature and second humidity of the target period can be obtained, providing a data basis for subsequent calculation of the impact of temperature and humidity on microwave absorption power.

[0031] Step S104: Based on the initial data, determine the first dielectric loss factor corresponding to the historical period. Step S106: Based on the basic data, determine the second dielectric loss factor corresponding to the target time period; In some preferred embodiments, determining a first dielectric loss factor corresponding to a historical time period based on initial data, and determining a second dielectric loss factor corresponding to a target time period based on basic data, includes: obtaining a dielectric loss coefficient; obtaining multiple historical data prior to the historical time period, wherein the multiple historical data includes at least multiple third temperatures and multiple third humidity levels; constructing a dielectric loss factor function based on the dielectric loss coefficient and the multiple historical data; determining the first dielectric loss factor based on the initial data and the dielectric loss factor function; and determining the second dielectric loss factor based on the basic data and the dielectric loss factor function.

[0032] Optionally, determining the change in the dielectric loss factor requires acquiring data from multiple time periods, conducting multiple experiments, obtaining a functional expression for the dielectric loss factor, and thus obtaining the correlation between temperature, humidity, and dielectric loss factor. Based on the second temperature and second humidity of the target time period, the change in the second dielectric loss factor can be determined.

[0033] Specifically, experiments were conducted based on multiple historical data points across different historical periods. Through regression analysis, the dielectric loss factor function was constructed as follows: ,in, For dielectric loss factor, The second dielectric loss factor, The second temperature, This is the second humidity level.

[0034] Optionally, taking saline waste liquid as an example, saline waste liquid is a type of wet waste, which is mostly a dilute solution with water as the solvent. Taking pure water as an example, during the drying process, there is only a temperature rise and phase change, without the influence of concentration or water content. Therefore, this is a simplified case of adaptive control of microwave drying of wet waste. At the start of drying (i.e., the historical period), the initial power corresponding to the magnetron is first set to P0 = 3000 W, the microwave frequency is 2450 MHz, and the mass m of the material is... t= 4.5 kg, first volume V0 = 4.5 L. It should be noted that the above data are all initial data obtained from historical periods. Furthermore, the first temperature T0 of the wet waste was measured to be 25℃ using an infrared thermometer (temperature sensor), and the first liquid level H0 in the microwave tank was measured to be 9.17 cm using a level gauge (level sensor). Based on the above initial data and the dielectric loss factor function, the first dielectric loss factor was determined.

[0035] Optionally, since the correlation between humidity and the dielectric loss factor is also related to the solute in the solution, for saline waste liquid, the calculated humidity and humidity dielectric loss factor can be fitted to an approximate value of 1.41073. Temperature changes have a significant impact on the dielectric loss factor, so after incorporating temperature, the dielectric loss factor is calculated as follows: Where 23.21797 is the suitable temperature coefficient, 0.97066 is the temperature-dependent dielectric loss coefficient, and T is the temperature. Based on the above method, the first temperature in the historical period is 25℃, therefore the first dielectric loss factor is... =12.44.

[0036] Optionally, you can set the power adjustment step size (interval time). t = 60 s, and the magnetron maintains its initial power P0 = 3000 W for 60 s. The second temperature T1 of the wet waste at 60 s is measured using an infrared thermometer. 60s = 34.3℃, the second liquid level height H1 in the level gauge test tank = H 60s = 9.17 cm. Based on the above data, the second dielectric loss factor is determined to be 34.3℃. = 9.77.

[0037] Step S108: Based on the initial data, basic data and the first dielectric loss factor, determine the electric field strength of the microwave field inside the microwave barrel, wherein the electric field strength of the microwave field is used to indicate the magnetron strength inside the microwave barrel. In microwave drying equipment, the magnetron is the key component for generating microwaves. The magnetron excites microwaves and transmits them into the microwave cavity, thereby creating an electric field inside the material (wet waste). The intensity distribution of this electric field is not uniform; rather, it exhibits an irregular distribution with "strong points" and "weak points." This non-uniformity is mainly due to the influence of physical phenomena such as reflection, refraction, and interference as electromagnetic waves propagate within the microwave cavity, as well as changes in the dielectric properties of the material.

[0038] The magnitude of the electric field directly affects the absorption and conversion efficiency of microwave energy by the material (wet waste). Areas with higher electric field strength absorb microwave energy more strongly, resulting in faster heating. However, excessively high electric field strength can also lead to localized overheating, even scorching or structural damage. Therefore, during microwave drying, it is necessary to rationally control the distribution and magnitude of the electric field to ensure uniform and rapid drying of the material, while avoiding overheating and scorching.

[0039] Furthermore, the electric field strength is also closely related to the physical properties of the material, such as its moisture content and density. Materials with higher moisture content have a stronger ability to absorb microwave energy, and therefore their internal electric field strength will be correspondingly greater. On the other hand, materials with higher density may reflect and scatter microwaves, thus affecting the distribution and magnitude of the electric field strength.

[0040] In some preferred embodiments, determining the electric field strength of the microwave field inside the microwave barrel based on initial data, basic data, and a first dielectric loss factor includes: determining a first absorbed power based on the initial data and basic data, wherein the first absorbed power is used to indicate the power absorbed by the drying of wet waste inside the microwave barrel; and determining the electric field strength based on the first absorbed power, microwave frequency, first volume, and first dielectric loss factor when the initial data includes microwave frequency and a first volume.

[0041] Optionally, the specific calculation method for electric field strength is as follows: in, The first dielectric loss factor at time t (historical period) For electric field strength, denoted as the first absorbed power, f as the microwave frequency, and V as the volume.

[0042] Optionally, taking the aforementioned saline waste liquid as an example, the microwave frequency of the magnetron is set to 2450 MHz, and the mass m of the material is... t = 4.5 kg, first volume V0 = 4.5 L, first dielectric loss factor =12.44, the electric field strength is calculated as follows: In some preferred embodiments, determining the first absorption power based on initial data and basic data includes: determining the time difference between a historical time period and a target time period; acquiring the specific heat capacity of the wet waste in the microwave barrel, the specific heat capacity of water, and the heat coefficient of water vaporization; determining the temperature difference based on a first temperature and a second temperature; and, if the initial data includes mass, determining the first absorption power based on the time difference, the specific heat capacity of the wet waste, the specific heat capacity of water, the heat coefficient of water vaporization, the temperature difference, the first humidity, and the mass.

[0043] Optionally, the first absorbed power is calculated as follows: Among them, c pd For the specific heat capacity of wet waste, c pw L is the specific heat capacity of water, and Lw is the heat coefficient of water vaporization. T represents the temperature difference. t is the time difference. M t The first humidity level is m t For clarity, it's important to note that the heat coefficient of water vaporization usually refers to the latent heat of vaporization of water, which represents the amount of heat required to change a unit mass of water from a liquid to a gaseous state at a given temperature. Under standard atmospheric pressure, the latent heat of vaporization of water is approximately 2260 kJ / kg (or 40.8 kJ / mol). It's crucial to understand that latent heat of vaporization is a process quantity; it represents the heat required for water to transition from a liquid to a gaseous state, not a state quantity.

[0044] Optionally, taking the above-mentioned saline waste liquid as an example, since water vaporization requires a temperature of 100 degrees Celsius to occur during the vaporization process of saline waste liquid, the highest temperature reaches 34.3 degrees Celsius between the initial stage (historical period) and the target period. The heat absorption of water vaporization accounts for a very small proportion, that is, the value of water vaporization is approximately 0 in the calculation.

[0045] Optional, the mass m of the material t = 4.5 kg, time difference t = 60 s, specific heat capacity c of wet waste pd =4200J (kg*℃), temperature difference T=9.3℃, = 4.5 kg / 60s × [4200 J / (kg·℃)×9.3℃], that is =2929.5 W.

[0046] Optional, based on =2929.5 W, from which the electric field strength can be obtained as follows: Right now = 620.06 V / m.

[0047] Step S110: Determine the microwave absorption power based on the electric field strength and the second dielectric loss factor, wherein the microwave absorption power is used to indicate the power that the wet waste in the microwave container can absorb. In some preferred embodiments, determining the microwave absorption power based on the electric field strength and the second dielectric loss factor includes: obtaining the microwave absorption coefficient; and, given that the initial data includes the microwave frequency and the basic data includes the second volume, determining the microwave absorption power based on the electric field strength, the second volume, the second dielectric loss factor, and the microwave frequency.

[0048] Optionally, the microwave absorption coefficient is 0.556 × 10⁻⁶. -10 The second volume is calculated as follows: in, Let r be the second volume and r be the radius of the microwave barrel. This refers to the height of the microwave oven.

[0049] Optional, microwave absorption power The calculation method is as follows: Taking the aforementioned saline waste liquid as an example, the microwave frequency is 2450 MHz, and the second dielectric loss factor... = 9.77, = 620.06 V / m, =4.5 L, =0.556×10 - 10 V -1 s -1 ×2450×10 6 Hz×9.77×(620.06 V / m) 2 ×0.0045 m 3 = 2302.6 W.

[0050] It should be noted that during the period from the historical time period to the target time period, because the temperature rose from 25 degrees to 34.3 degrees, the moisture in the wet waste inside the microwave container did not achieve the desired vaporization effect. = =4.5L.

[0051] Step S112: Adjust the power of the magnetron inside the microwave barrel based on the microwave absorption power.

[0052] In some preferred embodiments, adjusting the magnetron power inside the microwave barrel based on the microwave absorption power includes: determining the magnetron efficiency based on the initial power and the first absorption power, provided that the initial data includes the initial power corresponding to the magnetron; determining the required output power of the magnetron based on the magnetron efficiency and the microwave absorption power; and adjusting the magnetron power inside the microwave barrel based on the required output power of the magnetron.

[0053] Optionally, the magnetron power is calculated as follows: The efficiency of the magnetron includes both heating efficiency and microwave conversion efficiency. η 1 represents heating efficiency. η 2 represents microwave conversion efficiency.

[0054] Optionally, based on the magnetron power obtained above, the magnetron power for the current period is adjusted to 2358.0 W, so that the magnetron power supplied during the current period is equal to the power absorbed by the wet waste, thereby avoiding energy waste.

[0055] Through steps S102 to S112, the goal of determining the microwave absorption power for the current period based on the first dielectric loss factor, the second dielectric loss factor, and the electric field strength is achieved. This realizes the technical effect of adjusting the magnetron supply power to take into account changes in microwave absorption power, thereby reducing energy loss. Furthermore, it solves the technical problem of energy waste caused by the magnetron supply power exceeding the wet waste absorption power due to the lack of consideration for changes in microwave absorption power in related technologies.

[0056] Example 2 Based on the above embodiments and optional embodiments, the present invention also proposes an optional implementation method. Figure 2 This is a flowchart of an optional adaptive microwave power control method in Embodiment 2 of the present invention, as shown below. Figure 2 As shown, the method includes: Step S1: Input the initial power P0 corresponding to the magnetron; Step S2, in The initial power P0 of the magnetron is kept constant within time t. Step S3: Obtain the first temperature T of the wet waste using a temperature sensor. t And the second temperature The first liquid level height H of the wet waste is obtained through a level gauge. t and the second liquid level height .

[0057] Step S4, the second humidity of the wet waste during the target time period is M Where, m t The quality of wet waste M is the second humidity level of wet waste. t The first humidity level, H t This is the first liquid level height. This is the second liquid level height.

[0058] Step S5, in The first absorption power of wet waste within the time difference t (The first absorbed power is used to indicate the power absorbed during the drying of wet waste inside the microwave container.) c pd For the specific heat capacity of wet waste, c pw L is the specific heat capacity of water, and Lw is the heat coefficient of water vaporization. T represents the temperature difference. t is the time difference. M t The first humidity level is m t For quality.

[0059] Step S6, Electric field strength of the microwave field , The first dielectric loss factor of wet waste during historical periods can be used to calculate the electric field strength in the microwave field through the heat absorbed by the wet waste. .

[0060] Step S7, t+ Second dielectric loss factor of wet waste at time t (target time) .

[0061] Step S8, t+ t to t+2 Within time t, the microwave absorption power of the wet waste (microwave absorption power is used to indicate the power that the wet waste in the microwave container can absorb) is: , of which, the second volume r is the radius of the wet waste drying drum.

[0062] Step S9, t+ t to t+2 Within time t, the magnetron output power is adjusted according to the microwave absorption power of the wet waste, and the magnetron power of the drying device inside the microwave barrel is... ,in, η 1 represents heating efficiency. η 2 represents microwave conversion efficiency.

[0063] Step S10: Based on the magnetron power obtained above, perform adaptive regulation of the magnetron power.

[0064] Through the above steps S1 to S10, adaptive microwave power control can be achieved. Based on the energy required for drying wet waste, the microwave energy utilization efficiency and the drying rate of wet waste can be maximized.
