Abstract
Description
Technical Field
[0001] The present application relates to the technical field of dust collecting plate drying, and in particular to a dust collecting plate drying detection method and equipment. Background Art
[0002] In conventional air handling equipment, electrostatic dust removal is often used to adsorb dust particles in the air. The electrostatic dust removal method mainly connects the electrodes of the dust collecting plate through a power supply, applies voltage to the dust collecting plate to generate a certain current inside, and then the dust collecting plate can adsorb dust particles with static charge.
[0003] In order to maintain a good adsorption effect, the dust collecting plate will be disassembled and cleaned regularly. Since the dust collecting plate in a wet state cannot achieve the original adsorption effect, the dust collecting plate needs to be dried. Only after the dust collecting plate is in a dry state can it be reassembled into the air handling equipment to continue to adsorb dust particles in the air.
[0004] In the prior art, dust collecting plates are generally dried by thermal drying, that is, a dryer is used to deliver hot air to dry the wet dust collecting plates. However, the drying methods and devices in the prior art are unable to determine the drying degree of the dust collecting plates during the drying process, which may result in the dust collecting plates still being wet after the preset drying time is reached, or the dust collecting plates being dry before the preset time is reached, thereby causing unnecessary increase in energy consumption. Summary of the invention

[0026] If the drying status data is equal to the preset resistance value, the dust collecting plate is in a qualified state;

[0034] In the first time period at the beginning of the drying time, no drying status data is obtained;
[0035] In the second time period at the latter part of the drying time, the drying status data is acquired once at every preset time interval.
[0036] In some embodiments, the first time period is the first 70%-80% of the drying time, and the second time period is the last 20%-30% of the drying time.

[0059] Embodiment 1
[0060] like Figure 1 As shown, the first embodiment of the first aspect of the present application provides a dust collecting plate drying detection method, and the method comprises the following steps:
[0061] S101, obtaining drying status data of the dust collecting plate, where the drying status data can reflect the drying degree of the dust collecting plate;
[0062] For the drying status data, a humidity measuring instrument may be arranged in the space where the dust collecting plate is placed, and the humidity data measured by the humidity measuring instrument may be used as the drying status data; or a voltage may be applied to the dust collecting plate, and the current generated inside the dust collecting plate may be used as the drying status data, without any specific limitation.
[0063] In this embodiment, the drying status data is not limited to one dust collecting plate. It can be one dust collecting plate or multiple dust collecting plates. The number of dust collecting plates is not limited and can be selected according to actual production conditions. When the drying status data is obtained for multiple dust collecting plates, the multiple dust collecting plates are required to meet the preset conditions.
[0064] S102, determining whether the drying state data of the dust collecting plate meets the preset conditions,
[0065] There is no limitation on the specific form of the preset condition, which is determined based on the drying state data. For example, if the drying state data is the humidity data tested by a humidity tester, the preset condition may be the humidity data when the dust collecting plate is in a qualified state.
[0066] S1021. If the preset conditions are met, the dust collecting plate is in a qualified state;
[0067] S1022. If the preset conditions are not met, the dust collecting plate is still in an unqualified state, and the dust collecting plate continues to be dried.
[0068] The qualified state means that after drying, the humidity of the dust collecting plate is reduced to the point that when the dried dust collecting plate is installed in the air handling equipment, the dust collecting plate can achieve the original or close to the original adsorption effect.
[0069] The unqualified state means that after drying, the dust collecting plate has a high humidity. When the dried dust collecting plate is installed in the air handling equipment, the adsorption effect is quite different from the original one.
[0070] In this embodiment, the dust collecting plate to be dried can be a washable electret dust collecting plate, but is not limited to a washable electret dust collecting plate. Dust collecting plates with similar properties to the washable electret dust collecting plates can be dried by the dust collecting plate drying detection method provided in Example 1 of the present application.
[0071] Compared with the prior art, the dust collecting plate drying detection method provided in the first aspect of the present application obtains drying status data that can reflect the drying degree of the dust collecting plate, and determines whether the drying status data meets the preset conditions. If the preset conditions are met, the dust collecting plate is in a qualified state, and if the preset conditions are met, the dust collecting plate is in an unqualified state. Among them, the qualified state means that the humidity of the dust collecting plate is low, and the original adsorption effect can be achieved after being installed in the air treatment equipment. On the contrary, the unqualified state means that the humidity of the dust collecting plate is high, and the original adsorption effect cannot be achieved after being installed in the air treatment equipment. It is possible to judge the drying degree of the dust collecting plate during the drying process of the dust collecting plate, which solves the problem that the drying degree of the dust collecting plate during the drying process cannot be judged in the prior art.
[0072] like Figure 2 As shown, in some embodiments, the method for obtaining drying status data includes:
[0073] S1011, applying a preset voltage to the dust collecting plate;
[0074] The preset voltage can be 10kV or 20kV, and the specific value of the preset voltage is not limited, as long as the dust collecting plate can generate a current that can be detected by an existing current detection device after the preset voltage is applied to the dust collecting plate. The device for applying the preset voltage to the dust collecting plate can be a power supply, and the specific way of applying the voltage can be to connect the two electrodes of the power supply to the two electrodes of the dust collecting plate respectively, and turn on the power supply to apply the preset voltage.
[0075] S1012, obtaining the feedback current value of the dust collecting plate.
[0076] Since the dust collecting plate in an unqualified state has a certain amount of moisture, when the preset voltage is applied, the current generated in the dust collecting plate will flow through the water droplets attached to the dust collecting plate with better conductivity, so that the dust collecting plate area where the water droplets are attached is short-circuited, thereby reducing the current consumption. Therefore, during the continuous drying process, the dust collecting plate becomes drier and drier, and the feedback current generated in the dust collecting plate becomes smaller and smaller. The feedback current can be obtained through an existing current measuring device, which is not limited here.
[0077] In this embodiment, the dust collecting plate to which the preset voltage is applied is not limited to one, and multiple dust collecting plates may be stacked separately, and multiple power supplies are used to provide the same voltage to the multiple dust collecting plates, and feedback current of each dust collecting plate is obtained.
[0078] In some embodiments, the feedback current value is used as the drying status data.
[0079] When the feedback current value is used as the drying state data, determining whether the drying state data of the dust collecting plate meets the preset condition is specifically to compare the drying state data with the preset current value. The specific value of the preset current value needs to be determined according to the type of the dust collecting plate and the selection of the preset voltage.
[0080] Before determining the preset current value, experiments can be conducted on a variety of dust collecting plate products to measure the feedback current ranges of a variety of dust collecting plate products in a qualified state under different voltages, and a database can be established. In the actual drying process, the feedback current range of the dust collecting plate to be cleaned in a qualified state is selected according to the database, and this range is used as the preset current value in the preset condition.
[0081] like Figure 2 As shown, when the drying state data is a feedback current value, judging whether the drying state data of the dust collecting plate meets the preset conditions includes:
[0082] S102, comparing the drying state data with the preset current value,
[0083] S1021. If the drying state data is less than the preset current value, the dust collecting plate is in a qualified state;
[0084] S1022: If the drying status data is greater than or equal to the preset current value, the dust collecting plate is in an unqualified state.
[0085] Since the dust collecting board has lower humidity and less water in the qualified state than in the unqualified state, the integrated board resistance in the qualified state is larger, and the feedback current generated after the voltage is applied is smaller. The preset current value of the dust collecting board in the qualified state under the preset voltage can be obtained through the database. When it is less than the preset current value, the dust collecting board is in a qualified state. When it is greater than or equal to the preset current value, the dust collecting board is still in an unqualified state.
[0086] There is no specific limitation on the selection of the preset current value. Since different air handling equipment has different requirements on the humidity of the dust collecting plate, the specific selection of the preset current value can be adjusted according to the humidity requirements of the dust collecting plate of the actual air handling equipment.
[0087] In this embodiment, the preset voltage may be 10kV, and the preset condition may be that if the drying state data is less than 32μA, the dust collecting plate is in a qualified state, and if the drying state data is greater than or equal to 32μA, the dust collecting plate is in an unqualified state. The dust collecting plate to be tested is not limited to one, and may be multiple dust collecting plates. When multiple dust collecting plates meet the preset conditions, the drying process ends.
[0088] like Figure 3 In some embodiments, after obtaining the feedback current value in the dust collecting plate, the method further includes:
[0089] S1013, obtaining a feedback resistance value according to a preset voltage and a feedback current value, wherein the feedback resistance value is drying state data.
[0090] Specifically, the feedback resistance value can be calculated by Ohm's law or by a resistance measuring device, and the specific calculation method of the feedback resistance value is not limited. When the feedback resistance value is drying state data, the resistance value of the dust collecting plate when it is in a qualified state is used as the preset resistance value, and whether the drying state data of the dust collecting plate meets the preset condition is to compare the feedback resistance value with the preset resistance value.
[0091] Before determining the preset resistance value, experiments can be conducted on a variety of dust collecting plate products, the resistance values of a variety of dust collecting plate products in a qualified state can be measured, and a database can be established. In the actual drying process, the preset resistance value is selected according to the database.
[0092] like Figure 3 When the drying state data is a feedback resistance value, determining whether the drying state data of the dust collecting plate meets the preset condition includes:
[0093] S102, comparing the drying state data with the preset resistance value,
[0094] S1021. If the drying state data is equal to the preset resistance value, the dust collecting plate is in a qualified state;
[0095] S1022: If the drying status data is less than the preset resistance value, the dust collecting plate is in an unqualified state.
[0096] Since the humidity and water content of the dust collecting board in the qualified state are lower than those in the unqualified state, the resistance of the integrated board in the qualified state is greater than that of the dust collecting board in the unqualified state. The preset resistance value of the dust collecting board in the qualified state can be obtained through the database. When the feedback resistance value is less than the preset resistance value, the dust collecting board is in the unqualified state. When the feedback resistance value is greater than the preset resistance value, the dust collecting board is in the qualified state.
[0097] In some embodiments, obtaining the drying status data of the dust collecting plate further includes:
[0098] The drying status data is obtained once at a preset time interval until the obtained drying status data meets the preset requirements.
[0099] Specifically, the time interval between two consecutive acquisitions of drying status data is the preset time, and the length of the preset time is not specifically limited. When the preset time is short, the effect of real-time detection of the dust collecting plate can be achieved. When the interval time is long, it is an intermittent detection. The selection of the specific preset time can be set according to actual needs. Acquiring the drying status data once at each preset time interval can realize multiple detections of the drying status of the dust collecting plate during the drying process to ensure that the dust collecting plate is in a qualified state at the end of the drying process, or to prevent the dust collecting plate from reaching a qualified state before the end of the drying state, thereby causing unnecessary energy consumption increase.
[0100] like Figure 4 As shown, in some embodiments, obtaining the drying state data of the dust collecting plate further includes:
[0101] S301, obtaining initial drying state data of the dust collecting plate;
[0102] The initial drying state data of the dust collecting plate refers to the state value of the dust collecting plate before drying begins, that is, the moisture level of the dust collecting plate before drying.
[0103] S302, obtaining the wind speed and temperature of the hot air drying the dust collecting plate;
[0104] The hot air speed and temperature that the hot air device can provide are obtained. Generally speaking, in order to reduce the time consumed in the drying process, the hot air speed and temperature obtained are the maximum speed and the highest temperature that the hot air device can provide. The hot air device can be a combination of a fan and a heater, and is not specifically limited.
[0105] S303, obtaining drying time according to the initial drying state data, wind speed and temperature;
[0106] The drying time can be obtained by drying multiple dust collecting plates under different drying state data with hot air at different wind speeds and temperatures, and recording the time, thereby obtaining multiple sets of experimental drying time and establishing a database. In the actual drying process, the initial drying state data is obtained and the wind speed and temperature of the hot air are compared with the corresponding data in the database, and the experimental drying time closest to the data is used as the drying time. It should be noted that the drying time is the predicted time required to dry the dust collecting plate that has not been dried and is in an unqualified state to a qualified state, that is, the time required for the drying process.
[0107] S304: In the first time period at the beginning of the drying time, the drying state data is not obtained;
[0108] S305: In a second time period at the latter part of the drying time, the drying status data is acquired once at a preset time interval.
[0109] The sum of the first time period and the second time period is the drying time. It is predicted that the dust collecting plate will be in a dry state after the drying time, so in the first time period in the front section, the dust collecting plate is likely to be in a wet state, and there is no need to detect it, so the drying state data is not obtained.
[0110] However, the drying status data obtained is a predicted time, which may be affected by many factors, such as the humidity of the external air or the initial drying status data, wind speed and temperature data obtained are quite different from the corresponding data in the database, so it is necessary to obtain the drying status data once every preset time interval in the second time period in the latter section to detect whether the dust collecting plate is in a qualified state at the end of the drying time. This solution can concentrate on testing the dust collecting plate in the second time period before the end of the drying time, avoiding invalid testing of the dust collecting plate that is likely to be in an unqualified state in the first time period.
[0111] In some embodiments, the first time period is the first 70%-80% of the drying time, and the second time period is the last 20%-30% of the drying time.
[0112] For the proportion of the first time period and the second time period, when the first time period uses the first 70% of the drying time and the second time period uses the last 30% of the drying time, this setting is because the closest data in the database differs greatly from the actual data, so more concentrated detection is performed on the second time period. When the first time period is the first 80% of the drying time and the second time period is the last 20% of the drying time, this setting is because the closest data in the database differs little from the actual data, and there is no need to perform too many detections on the drying process.
[0113] like Figure 4 As shown, in some embodiments, in the second time period of the drying time, after obtaining the drying state data once at a preset time interval, the method further includes:
[0114] S102, judging whether the drying state data meets the preset conditions,
[0115] S1021. If the preset conditions are met, the dust collecting plate is in a qualified state, and the drying is terminated;
[0116] In the second time period, the drying status data is obtained once at a preset interval. When the drying status data obtained at any time meets the preset conditions, it proves that the dust collecting plate is in a qualified state, and the drying can be terminated. This setting can stop the drying process in time when the dust collecting plate meets the preset conditions and is in a qualified state, effectively reducing ineffective drying and reducing the energy consumption of the drying process.
[0117] S1022: If the preset condition is not met, continue drying, and obtain drying status data once at a preset time interval until the drying status data meets the preset condition.
[0118] If the dust collecting plate does not meet the preset conditions, it proves that the dust collecting plate is still in an unqualified state and needs to be dried further and the drying state conditions are obtained further until the obtained drying state conditions meet the preset conditions, so as to prevent the dust collecting plate from being in an unqualified state at the end of the predicted drying time.
