[0002] The technical field of chlorine dioxide disinfection and purification powder mainly involves the preparation processes and application technologies of disinfectants and purifying agents. This field includes key technologies such as the chemical reaction principles of chlorine-based compounds such as chlorates and chlorites, the selection of stabilizers, pH value adjustment, and the control of the active ingredient content. At the same time, it also involves physical processing technologies such as granulation, drying, and screening during the powder preparation process. Such technologies are widely used in fields such as medical and health, food processing, water treatment, and public place disinfection. However, in the prior art, during the preparation process of chlorine dioxide disinfection and purification powder, there is a lack of an accurate control mechanism for the acidification degree of silica powder, resulting in limited stability of the matrix structure; a quantitative and batch input system has not been established during the chlorate feeding process, leading to uneven distribution of active ingredients. Therefore, improvements are needed. Summary of the Invention

[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] Please refer to Figure 1 , the present invention provides a technical solution, a production process of a chlorine dioxide disinfection and purification powder, including the following steps: Based on dry silica gel powder and acidified control particles, weighing comparison and premixing are carried out, multiple intermittent stirrings are performed through step feeding, then temperature regulation and moisture content detection are carried out, the acidity is detected after drying and the acidity value is recorded to obtain a silica gel acidification matrix; Based on the silica gel acidification matrix, chlorate particles are added and the solid-phase ratio is detected, mixing is carried out through quantitative batch input and stirring, then temperature maintenance is carried out and the solubility parameter is recorded synchronously, and a chlorate uniform substance is obtained after detecting the acidity value; Based on the chlorate uniform substance, a porous dispersant is added and the added amount is recorded, rotary mixing is carried out through multi-stage control, then the viscosity is immediately detected and the viscosity value is recorded, and the component dispersion is determined after detecting the fluidity to obtain a porous carrier complex; Based on the porous carrier complex, heating is carried out and a constant temperature state is maintained, multi-period measurement is performed through a closed heating device, then the temperature and mass change are recorded and the duration data is accumulated and then stage induction is carried out, and a heat-treated formed body is obtained after detecting the fusion degree; Based on the formed body after heat treatment, cooling and dispersion are carried out. The particle size is detected by multi-stage screening and the particle size value is recorded. Subsequently, after determining the surface agglomeration degree, re-drying is performed and the structural parameters are recorded synchronously. After detecting the moisture residue, the dry particle matrix is obtained. Based on the dry particle matrix, chlorinating agent spraying is carried out and the spraying amount is recorded. Subsequently, the gas-phase release rate is detected and the release value is recorded. After mixing with the moisture-proof agent, the mixing parameters are recorded. Finally, sealed packaging is carried out and the packaging batch information is recorded to obtain the chlorine dioxide disinfection and purification powder.

[0015] The steps for obtaining the silica acidified matrix are specifically as follows: Based on the dry silica powder and acidification control particles, weighing comparison is carried out and the weighing error range is controlled. The mixing ratio is recorded by multi-stage weighing and the premixing time is set. The material contact degree is detected and the mixing ratio is corrected to obtain the matrix raw material combination. Based on the matrix raw material combination, multiple intermittent stirrings are carried out in a stepwise feeding manner. The stirring time is regulated by successive feeding and the stirring uniformity is monitored. Temperature adjustment is carried out and the moisture content is detected in cooperation to obtain the mixed system. Based on the mixed system, the environmental humidity and drying duration are controlled. The drying rate is compared by fixed-point sampling and the acidity change is monitored. The acidity is detected and the acidity value is recorded to obtain the silica acidified matrix.

[0016] Specifically, based on the dry silica powder and acidification control particles, the weighing accuracy is determined according to the empirical data of the existing weighing error range. For example, the error tolerance calibrated multiple times in the previous experiments is set to ±0.1 g. Then, the masses of the dry silica powder and acidification control particles are weighed batch by batch according to this tolerance and recorded one by one. After the recording is completed, multiple comparisons are made. If it is found that a certain weighing deviates from the tolerance range of ±0.1 g, calibration is immediately carried out again and weighing is performed again. When all the raw material weighing values meet this tolerance interval, the premixing time is set. At this time, the premixing time can be set between 120 seconds and 180 seconds by combining the analysis of previous production experiments or referring to the operation habits of the same type of acidification process. In practical applications, it will be appropriately adjusted according to the particle size of the dry silica powder and the density difference of the acidification control particles. After the premixing starts, the dispersion state between the materials is observed successively and the determination range of the material contact degree is set. For example, it is determined whether the mutual adhesion on the solid surface is less than 10% by visual comparison method. If it is higher than 10%, the premixing time is continued to be adjusted or the material is switched to a larger container for dispersion. Then, the mixing ratio is corrected by observing the preliminary combination situation between the materials. If the inspection result shows that the proportion of the dry silica powder is lower than the target value, the dry silica powder is supplemented according to the detailed data of multiple weighings to make it return to the tolerance range. After completing this series of operations, the matrix raw material combination is obtained.

[0017] Based on the matrix raw material combination, the stepwise feeding method can be adopted for multiple intermittent stirrings. First, set the interval duration for each feeding. For example, take an interval of 30 seconds to 60 seconds. The selection of this interval usually refers to the statistical data of the particle dispersion efficiency in previous tests. After each feeding, perform a short-time stirring and observe the matching state. If the stirring uniformity still does not meet the requirements as shown by comparing the particle dispersion range (such as observing whether the mixing ratio of dry silica gel powder and acidified control particles at multiple sampling points in the stirring container is within the floating range of ±5%), then appropriately increase the interval duration. After confirming uniform dispersion, continue with the next feeding. After all feedings are completed, adjust the temperature, which can be maintained between 20°C and 25°C. This range can be determined by prior experiments. If the temperature exceeds 25°C, consider increasing ventilation equipment or cooling measures. If it is lower than 20°C, start local heating or insulation of the enclosed space. At the same time, cooperate with the detection of the moisture content, which can be detected every 10 minutes. When the moisture content is maintained within the range of 3% to 5%, it is determined to reach the target range. After all operations are completed, a mixed system is obtained.

[0018] Based on the mixed system, during the execution process, the environmental humidity and drying duration should be controlled. First, keep the environmental relative humidity between 30% and 40%. This value is from the optimal interval statistically obtained in previous drying tests of multiple batches of materials. If the humidity exceeds 40%, turn on the dehumidification equipment and continuously record the dehumidification rate. At the same time, set the drying duration according to a reference period of 10 minutes to 20 minutes. If it is found through fixed-point sampling comparison that the drying rate significantly deviates from the original statistical curve during this process, then appropriately extend or shorten the drying time in the next period. If it is monitored that the acidity value rises to the pre-determined upper limit (for example, when the pH is lower than 3), it indicates that the acidification trend is accelerating. The drying duration can be shortened to avoid excessive acidification, and record the corresponding pH value after each sampling. When the results of multiple samplings tend to be stable and the acidity value remains within the range of 3 to 5, end the drying operation to obtain the silica acidified matrix.

[0019] The specific steps for obtaining the chlorate homogeneous substance are as follows: Based on the silica acidified matrix, select the mass of chlorate particles and record the particle size range. Uniformly disperse them in the container by setting the rotation speed and perform stirring, monitoring the particle interaction intensity to obtain a particle mixture; Based on the particle mixture, implement quantitative batch feeding and set the stirring frequency. Check the feeding rate by repeated weighing and compare with the solid-phase ratio, continuously monitor the particle size change to obtain a solid-phase distribution structure; Based on the solid-phase distribution structure, maintain the temperature and synchronously record the solubility parameters. Monitor the dispersion state through periodic sampling and detect the acidity value again to obtain the chlorate homogeneous substance.

[0020] Specifically, based on the silica acidified matrix, first determine the mass of the chlorate particles, which can be referred to previous similar experiments or actual production line statistics. For example, set the single batch of chlorate particles to be in the range of 200g to 300g. Then record the particle size range. Generally, use a sieve shaker to detect the chlorate particles in segments. If the proportion of particles larger than 1mm or smaller than 0.1mm exceeds 10%, they need to be separated separately and processed otherwise. When the screening result meets the preset particle size range, it can be evenly dispersed in the stirring container by setting the rotation speed. The rotation speed value is usually determined by previous tests. For example, control it between 60 revolutions per minute and 80 revolutions per minute, and observe the particle interaction intensity at all times after the dispersion starts. If obvious agglomeration or adhesion occurs, the rotation speed can be slightly reduced or the dispersion time can be appropriately extended. If more than half of the particles continue to adhere to each other at the observation point, it can be defined as exceeding the agglomeration threshold, which is determined by multiple rounds of comparative tests. After adjusting to suitable conditions, complete the stirring to obtain a particle mixture.

[0021] Based on the particle mixture, implement quantitative batch input and set the stirring frequency. First, according to the total amount of the particle mixture, pre-plan that the input amount for each time accounts for 10% to 15% of the total amount. This is an empirical range determined comprehensively according to the load capacity of the batching container and the stirring efficiency. After the input, check the feeding rate by repeated weighing and compare it with the solid phase ratio. If the deviation of any feeding exceeds ±2g, re-detect and correct the feeding value. At the same time, continuously monitor the particle size change. Small samples can be taken regularly at different positions in the stirring container, and the particle size distribution can be observed by sieving method to see if it is uneven. If the particle size is concentrated in the too large or too small interval after a certain batch is input, the stirring frequency can be appropriately increased to improve the dispersion condition. After all the feeding is completed, summarize the particle size observation and weighing data for each time. If it is found by comparison that all parameters are maintained within the previous measured range (for example, the particle size distribution is concentrated between 0.1mm and 0.8mm, and the deviation ratio does not exceed 5%), the feeding process is judged to be qualified, and finally a solid phase distribution structure is obtained.

[0022] Based on the solid-phase distribution structure, maintain the temperature and synchronously record the solubility parameter. The temperature can be maintained in the range of 35°C to 45°C, which is determined by comparing previous rounds of solubility tests. If the temperature is lower than 35°C during this monitoring period, local heating can be carried out. If it is higher than 45°C, moderate cooling can be carried out. Samples in the container are periodically collected within this range to monitor the dispersion state. After each sampling, the solubility of the solution part can be detected. At this time, if the solubility is lower than the set threshold (for example, when 50 g of solute is dissolved in 100 g of solvent, it can be regarded as basically completed, and this threshold is set by the actual characteristics of the material and the accumulation of historical data), then the temperature is maintained for a period of time. If the solubility is still lower than the threshold after repeated detections, the temperature maintenance duration can be appropriately extended, and the acidity value is detected again. When the results of multiple detections show that the solubility is stable within the empirical range and the pH value remains between 3 and 5, this control process is completed, and a chlorate homogeneous substance is obtained.

[0023] The steps for obtaining the porous carrier complex are specifically as follows: Based on the chlorate homogeneous substance, check the ratio of the porous dispersant and record the input amount. By continuously monitoring the stirring torque to maintain a balanced speed, use a rotating stirrer to stir to obtain a dispersion composition; Based on the dispersion composition, adjust the rotation speed in a multi-stage manner and add materials at different times. Record the viscosity value by detecting the viscosity and calibrate the mixing uniformity. Determine the feeding amount in combination with the operation frequency to obtain a multi-layer mixed structure; Based on the multi-layer mixed structure, detect the fluidity and analyze the degree of component dispersion. Compare the viscosity differences by segmental sampling and verify the stability to obtain the porous carrier complex.

[0024] Specifically, based on the chlorate homogeneous material, first confirm the proportion range of the porous dispersant. The proportion of the porous dispersant can be initially set at 5% to 10% with reference to the statistical data of particle size distribution and porosity in early tests. If the deviation of the feeding amount exceeds ±2 g during actual feeding, it is necessary to reweigh and record the feeding value. After feeding, continuously monitor the stirring torque. For example, determine the torque range under normal working conditions as 0.3 N·m to 1 N·m. This value can be obtained from the summary of multiple small-scale stirring tests. If the real-time monitoring value exceeds 1 N·m, it indicates that the stirring resistance is large, and the stirring speed can be appropriately reduced or a small amount of solvent can be added. If it is lower than 0.3 N·m, it may indicate insufficient materials or weakened stirring force, and it can be corrected by rechecking the feeding amount or adjusting the angle of the stirring paddle. During this process, record the torque reading every 5 minutes and compare it with the above effective range. For example, compare each record with the pre-set 0.3 N·m to 1 N·m. If the monitoring results of two consecutive times are within this range, maintain the existing stirring plan. When the operating torque is within the set range and there is no obvious accumulation or caking of the porous dispersant in the stirring container, then evaluate whether the stirring equilibrium speed is close to the established standard by combining the rotation speed statistics of the stirrer. This standard is usually determined by the previous stirring test. For example, the rotation speed of 30 to 40 revolutions per minute can be used as the initial stable range. If the deviation is too large, continue to fine-tune until the chlorate homogeneous material and the porous dispersant are in full contact and the torque is maintained within a reasonable range to obtain the dispersion composition.

[0025] Based on the dispersion composition, first determine the rotation speed range required for multi-stage control. The rotation speed can be initially divided into 50 to 80 revolutions per minute with reference to the viscosity and flow characteristics of the dispersion composition. In the time-sharing feeding link, the total feeding amount can be divided into several batches, such as 5 to 8 batches. When each batch is fed, first maintain a lower rotation speed, such as 50 revolutions per minute, for preliminary stirring, and then gradually increase to 80 revolutions per minute and stir for another 2 to 3 minutes after an interval of 1 to 2 minutes. During the process, if the measured viscosity is lower than the pre-set 1.2 Pa·s, it indicates better fluidity, and the existing feeding frequency can be maintained. If the viscosity exceeds 1.5 Pa·s, it means the viscosity is too high, and the stirring time can be extended or the single-batch feeding amount can be reduced. The above viscosity range and threshold are usually determined by the pre-test data of the dispersion composition. Each viscosity detection can use a rotational measuring instrument and record the reading. Compare each reading with the set 1.2 Pa·s to 1.5 Pa·s. If most of the readings are stable within this range, the viscosity can be considered normal. In addition, determine the specific feeding amount for each batch in combination with the operation frequency. It can be obtained from the previous research that, for example, when the total amount is 100 g, 15 g to 20 g is fed for each batch. After the feeding is completed, comprehensively check the actual feeding times and viscosity records. If the overall error is controlled within ±5% and there is no large-scale fluctuation in the viscosity difference, it is determined that the time-sharing feeding process is smooth, and a multi-layer mixed structure is obtained.

[0026] Based on a multi-layer hybrid structure, the detection of fluidity can be carried out by placing the mixture in a funnel with a specified pore size and observing its natural outflow time. If the outflow time is between 5 seconds and 10 seconds, it indicates that the fluidity is within the normal range, which is mostly set by averaging multiple measurements in early tests and adding a certain safety margin. If the outflow time exceeds 10 seconds, it indicates insufficient fluidity, and dispersing materials can be added or the mixing ratio can be adjusted again. If it is less than 5 seconds, it may lead to structural instability, and the feeding components need to be checked or the stirring intensity needs to be reduced. After the detection, the degree of component dispersion is analyzed. Samples can be taken at three points, namely the upper, middle, and lower parts of the stirring container wall, and the mass ratio of each component in the samples is compared to see if the deviation from the previously set total ratio does not exceed ±5%. If the detection result at a certain point deviates significantly, local uneven dispersion may exist, and the stirring times can be increased or the stirring duration can be extended. Subsequently, samples need to be taken at different intervals to compare the viscosity differences. Samples can be taken every 2 minutes and the detection results are recorded and compared with the initial viscosity. When the difference values of multiple detections are not greater than 0.2 Pa·s, it can be considered basically stable. If there are large deviations during the process, the stirring speed and the uniformity of feeding need to be detected again. After stability, a porous carrier composite is obtained.

[0027] The steps for obtaining the formed body after heat treatment are specifically as follows: Based on the porous carrier composite, set the heating range and start heating up. Determine the preheating duration by recording the heating rate and the material performance, and compare the data with the initial state of the material to obtain the heating preparation state. Based on the heating preparation state, maintain a constant temperature and measure the temperature and mass changes at intervals. By recording the measured values at each time period separately and summarizing the material fusion tendency, screen the changing sections to obtain a staged fusion structure. Based on the staged fusion structure, accumulate the duration data, organize the heating-up records, and compare the degree of fusion. By comparing the material transformation situation, count the change range to obtain the formed body after heat treatment.

[0028] Specifically, based on the porous carrier complex, first set the heating range. The temperature range can be initially set to 50°C to 70°C in combination with the previous test records. This temperature range is a reference value obtained through multiple rounds of material thermal property tests and safety factor considerations. After setting, start the heating and observe the temperature rise curve in real time, and record the heating rate at the same time. If the heating rate exceeds 5°C per minute, it may cause the surface of the material to be heated too fast, and it can be controlled by weakening the external heating power or adding a heat dissipation device outside the container. If the heating rate is lower than 1°C per minute, it may extend the overall operation time, and the heating power can be appropriately increased. In addition, the initial state of the porous carrier complex can be checked before heating, for example, its appearance color and density distribution can be detected at room temperature, and compared with the benchmark data of the previous same batch or similar batches. If there is no significant difference, preheating can be carried out normally. If obvious color deviation or hardening tendency appears, the operation should be suspended and the previous stirring process and ingredient measurement should be rechecked. When the temperature curve remains stable in a short time and the material shows no shedding or serious caking, it can be considered that the preheating process reaches the planned duration and the heating preparation state is obtained.

[0029] Based on the heating preparation state, maintain the temperature stably within the previously set target range, such as 50°C to 70°C. The appropriate constant temperature duration can be selected according to the phase change law of the material at this temperature. Generally, 20 minutes to 30 minutes can be set as the initial period first. If the measured temperature or mass change during this period deviates significantly from the average value accumulated in the previous period, such as the mass reduction exceeds 5% or the temperature fluctuation is greater than ±2°C, the operation can be stopped and the heating uniformity can be confirmed. When measuring at intervals, the instantaneous values of temperature and mass can be recorded every 5 minutes, and compared with the previously set range of 50°C to 70°C and the mass fluctuation threshold. If the detection results fall within this range multiple times and there is no large deviation, the data can be summarized, and the fusion tendency of the material can be summarized within the same period. If most of the measured values show small mass changes and the surface begins to show semi-fluid or softening characteristics, it can be regarded as the generation of preliminary fusion. Next, after analyzing the temperature and mass curves collected during this period, the local abnormal data can be rechecked. If no abnormality is confirmed, continue to maintain the constant temperature until the end of the next period, and select the section with the most concentrated temperature and mass changes according to the change trend of the final multiple measurements to obtain the stage fusion structure.

[0030] Based on the phased fusion structure, first sort out the cumulative duration data. For example, calculate the intervals between the recorded heating start times and each measurement time point, and then match the corresponding temperature values and mass values item by item to form a heating record. Compare the fusion degree values of the material during these time periods. This fusion degree can refer to the degree of phase change measured in the previous stage. If multiple records show that the fusion degree deviates from the average level by more than 10%, it can be marked as an abnormal section in subsequent statistics and additional comparisons are made. If the fusion degrees at each measurement point fluctuate within 10%, it indicates that the fusion process is relatively stable. When the sorted heating record shows that the temperature and mass have reached the specified change range, for example, the temperature is stable between 60°C and 65°C and the mass fluctuation does not exceed 3%, it means that the material transformation situation is connected with the previous steps. Finally, combine these statistical results to check the time consumed in the overall heating process and compare whether there are obvious deviations from the initially determined operation outline. If it is within the acceptable range, make a final comparison of the transformation situation of the material in the high-temperature environment and record the change range to obtain the formed body after heat treatment.

[0031] The steps for obtaining the dry particle matrix are specifically as follows: Based on the formed body after heat treatment, actively ventilate to cool down and observe the surface state, and compare the overall transformation by measuring the lower temperature limit and recording the color deviation to obtain the cooling morphology structure; Based on the cooling morphology structure, use a multi-stage screening device to detect the particle size and record the particle size values. Eliminate abnormal particles by comparing the screening results, and classify and summarize according to the particle morphology to obtain a particle dispersion system; Based on the particle dispersion system, determine the surface agglomeration degree and then perform re-drying while synchronously recording the structural parameters. Measure the moisture residue through stage monitoring and sort out the drying process data to obtain the dry particle matrix.

[0032] Specifically, based on the formed body after heat treatment, first, set up a fan with adjustable air volume in a ventilated place and start low-speed air supply. Initially, set the fan operation frequency to 20 to 30 revolutions per minute. This value can be determined by combining the measurement results of the cooling rate of the same material in the previous tests. Subsequently, continuously monitor the temperature. For example, by arranging thermocouple sensors at different positions and recording the temperature values every 5 minutes. If it is found that the temperature drop rate at a certain monitoring point deviates significantly from other points, such as the difference exceeding 5°C within the same period, it indicates uneven ventilation and the fan orientation needs to be adjusted appropriately. During this period, special attention should be paid to the lower temperature limit. The appropriate cooling safety range can be selected through small-scale experiments in the early stage, such as not lower than 15°C. If the actual monitored temperature is close to 15°C, continue to reduce the fan speed. Set a reference period, such as 30 minutes, during the cooling process. If the temperature has stabilized between 15°C and 20°C and there are no signs of surface cracks or looseness after reaching this period, stop the active cooling. Then, observe the color deviation of the formed body. The initial color can be compared with the photographed records every 5 minutes. If the deviation exceeds the set 5% threshold, it is considered that the color has changed significantly. This 5% threshold can be obtained from the statistical data of similar materials in the past under similar cooling methods. If the actual deviation is lower than 5%, it indicates that the color is still within the range close to the original appearance. After summarizing the above temperature and color data, compare them with the records of the same batch of tests in the early stage. If multiple indicators are within the safe range, it is recognized that the current cooling is completed, and the cooled morphological structure is obtained.

[0033] Based on the cooled morphological structure, first, prepare a multi-stage screening device and set the screen aperture. The aperture can be selected as four levels of 0.1mm, 0.3mm, 0.5mm, and 0.8mm by combining the previous particle size distribution analysis results of this type of material. Place the cooled material on the screening device for step-by-step vibration screening. The vibration frequency of each level can be set in the range of 50 to 80 times per minute. This range is selected after considering different particle looseness and the risk of screen blockage. During the screening process, check the number and weight of the particles in the receiving tray below every 2 minutes and compare them with the previously statistically regular distribution ratio. If the particle ratio difference of a certain level exceeds ±5%, it indicates that the particle morphology of this material has abnormal conditions. Unqualified particles can be removed through manual selection or additional screening procedures and these abnormal data are recorded. Then, classify them according to the particle morphology. For example, spherical or quasi-spherical particles are classified into the first category, and irregular debris is classified into the second category. When classifying, a morphological determination standard can be set. This standard can be derived from the average values of multiple batches of tests on particle roundness and surface smoothness. If the morphological parameters of any particle deviate significantly from the established standard, such as the roundness being lower than 0.6 or higher than 0.9, it is stored separately. After completing all detections and summarizing the classification data, a particle dispersion system is obtained.

[0034] Based on the particle dispersion system, it is necessary to determine the surface agglomeration degree and perform re-drying. During the operation, the previously classified particles can be stacked in categories on a flat surface according to their categories, and then each area is observed at a fixed angle to see if more than 10% of the particles adhere to each other or form clusters. This 10% threshold can be determined through multiple actual production evaluations. If the agglomeration degree of a certain area is significantly higher than 10%, try manual dispersion or treat it with a mild oscillation method. If it still cannot be separated after several oscillations, it can be determined as unusable particles. After the agglomeration degree detection is completed, the qualified particles are placed in a low-temperature drying environment, and the temperature can be maintained in the range of 30°C to 35°C. This range is derived from the historical record statistics of particle brittleness and moisture evaporation rate, and 15 minutes to 30 minutes is set as a drying cycle. If the moisture content is measured to be close to the target value, such as between 0.5% and 1%, at the end of this cycle, stop drying and measure again. If both consecutive readings are within this range, it is determined that the drying is completed. At the same time, record the structural parameters during the drying process, such as whether there are large-area microcracks or significant color changes on the particle surface. If any abnormalities are found, check the feeding and temperature control of each process again. After all processes are qualified, a dried particle matrix is obtained.

[0035] The steps for obtaining the chlorine dioxide disinfection and purification powder are specifically as follows: Based on the dried particle matrix, determine the ratio of the chlorinating agent and set the spraying rate. By monitoring the spraying layer thickness in real time and recording the spraying duration, and comparing the material humidity deviation, a chlorination spraying system is obtained; Based on the chlorination spraying system, monitor the gas-phase release rate and record the release value. By monitoring the release process and setting the continuous monitoring period, judge the stable trend of the release to obtain the release monitoring result; Based on the release monitoring result, add a moisture-proof agent and record the mixing parameters. After detecting the state, perform sealed packaging and record the packaging batch information to obtain the chlorine dioxide disinfection and purification powder.

[0036] Specifically, based on the dry granular matrix, it is necessary to first determine the ratio of the chlorinating agent. The test records of the interaction between the chlorinating agent and the granular matrix in the early stage can be referred to. For example, the ratio of the chlorinating agent is gradually increased within the range of 5% to 10% and the change in the material humidity is observed. The ratio with relatively stable humidity change is selected as a reference. If the actual value deviation during feeding exceeds ±2 g, it should be weighed again. Subsequently, the spraying rate is set. A preliminary attempt can be made within the range of spraying 2 g to 5 g per minute. After each spraying, the thickness of the sprayed layer is monitored in real time. For example, it is measured at two diagonal points in the spraying area and compared with the expected uniform layer thickness. If the difference exceeds 1 mm, it is regarded as uneven distribution. The spraying angle can be adjusted or the spraying time can be increased or decreased. During this period, the total spraying duration should be recorded and the deviation of the material humidity should be compared. The moisture content can be detected before and after spraying respectively. If the increase in the moisture content does not exceed 1%, it indicates that the humidity is within the acceptable range. If the increase exceeds 2%, the ratio of the chlorinating agent should be reduced or the dosage of each spraying should be decreased. Repeat this process and summarize the humidity and spraying data to finally obtain the chlorination spraying system.

[0037] Based on the chlorination spraying system, the gas-phase release rate is monitored. Multiple detection points can be set above the spraying area. The gas sensor pre-selected through comparative tests is installed about 10 cm away from the spraying surface. The release value is collected once per minute and recorded. If the increase in the release rate exceeds 5% in two consecutive collections, it is judged that it has increased significantly. Spraying can be appropriately slowed down or paused to avoid out-of-control. If the release rate is always lower than 2%, it indicates that the gas-phase release is inactive. The spraying speed can be finely adjusted to make it in the stable range of 2% to 5%. This range is obtained from the comparative analysis of the usage of different chlorinating agents and the release rate in the past. During the entire monitoring process, a continuous monitoring period needs to be set, such as 30 minutes to 60 minutes. If the release curve tends to be flat and there are no large fluctuations within this period, such as the difference between multiple detections remains within ±1%, the records can be summarized and this stable trend can be used as the final benchmark to obtain the release monitoring result.

[0038] Based on the release monitoring result, the moisture-proof agent is put into the dry granular matrix and the actual feeding amount is recorded. The reference range of this feeding amount can be derived from the early statistical data of the moisture absorption of such powders in different humidity environments. For example, the moisture absorption amount within the range of 3% to 5% can be formulated with 0.5% to 1% of the moisture-proof agent. If the deviation during feeding exceeds ±1 g, it is necessary to pause and weigh accurately again. After the feeding is completed, thorough mixing is carried out. The surface state of the particles is checked every 5 minutes during the mixing process. If a large amount of adhesion or caking is found, the dispersion operation is appropriately increased. After confirming that the surface state remains in the original loose particle appearance, it is then sealed and packaged. When packaging, the packaging batch information can be recorded item by item, such as the input date, output, and formula identification. When all inspections are normal, the chlorine dioxide disinfection and purification powder is obtained.
