Description

Technical Field

[0001] The invention relates to the technical field of anion liquid preparation, and in particular to a preparation process and equipment for anion liquid extracted by tourmaline plants. Background Art

[0002] Negative ions have the function of purifying the air. They can combine with tiny particles such as dust, smoke, bacteria, and viruses in the air to make them condense and settle, thereby effectively removing pollutants from the air and improving air quality. For example, in a closed indoor space, such as an office or bedroom, negative ions can reduce dust particles in the air, make the air fresher, reduce people's exposure to allergens, and reduce the risk of respiratory diseases. At present, the preparation process of many negative ion liquids is relatively complicated, involving multiple steps and complex operating procedures. For example, some traditional processes require the use of a large amount of chemical reagents for processing, which not only increases production costs, but may also pollute the environment. At the same time, complex processes require professional equipment and technicians, which increases production thresholds and operating costs.

[0003] Chinese patent application publication number: CN118165554A discloses a method for preparing negative ion liquid paint based on tourmaline plant extraction. The method processes tourmaline to obtain a supernatant, processes plants to obtain plant extract, mixes the supernatant with the plant extract to obtain a negative ion liquid, obtains the paint viscosity and the paint particle size to calculate the roughness characterization parameter, determines whether to adjust the initial negative ion liquid and paint mixing ratio, adds the negative ion liquid and the paint into a centrifuge to obtain the negative ion liquid paint, obtains a negative ion liquid paint sample for wall smearing test, adjusts the wall temperature and light intensity, continuously obtains the negative ion concentration at several points on the wall, calculates the negative ion concentration fluctuation value and the negative ion concentration uniformity based on the negative ion concentration, calculates the negative ion liquid paint performance characterization value, and determines whether the negative ion liquid paint meets the standard. The method can improve the performance and practical value of the negative ion liquid paint.

[0004] It can be seen that the prior art has the problem of poor accuracy in analyzing the raw materials for preparing negative ion liquid extracted from tourmaline plants, resulting in the selection of tourmaline containing a large amount of impurities for preparation in the subsequent preparation process, causing the negative ion liquid to contain a low negative ion content, thereby affecting the performance of the negative ion liquid. Summary of the invention

[0005] To this end, the present invention provides a preparation process and equipment for negative ion liquid extracted from tourmaline plants, so as to overcome the problem that the analysis of the raw materials for the preparation of negative ion liquid extracted from tourmaline plants in the prior art is poor in accuracy, resulting in the selection of tourmaline containing a large amount of impurities for preparation in the subsequent preparation process, resulting in a low negative ion content in the negative ion liquid, thereby affecting the performance of the negative ion liquid.

[0006] To achieve the above object, the present invention provides a preparation process of negative ion liquid extracted from tourmaline plants, comprising:

[0007] Acquire characteristic data of tourmaline, select tourmaline that meets the conditions for preparing raw materials by a light analysis method or an impurity content analysis method based on the characteristic type of tourmaline, and mix, stir, and grind the tourmaline that meets the conditions for preparing raw materials with a 60% sodium hydroxide solution to obtain a slurry;

[0008] adding hydrochloric acid to the slurry to obtain a first mixture, heating and stirring the first mixture for a first preset time, filtering to obtain a first mixed solution, and adjusting the pulverization parameters or the preset average chromaticity value based on the type of the filtered product;

[0009] After crushing the plant, adding water, heating and stirring for a second preset time, extracting the plant extract to obtain a second mixed solution;

[0010] Mixing the first mixed solution with the second mixed solution to obtain a negative ion liquid;

[0011] Based on the solution state of the prepared negative ion liquid after shaking and the purification effect of the smoke removal test on the negative ion liquid, it is determined whether to adjust the adjustment coefficient of the crushing parameter or the tourmaline characteristic type judgment parameter.

[0012] Furthermore, the screening out of tourmaline that meets the conditions for preparing raw materials includes:

[0013] If the characteristic type of the tourmaline is the first characteristic type, determine to select the tourmaline that meets the conditions for preparing the raw material by using the light analysis method;

[0014] If the characteristic type of the tourmaline is the second characteristic type, determine to screen out tourmaline that meets the conditions for preparing raw materials by using the impurity content analysis method.

[0015] Furthermore, the characteristics of tourmaline include:

[0016] If the transparency of the tourmaline is greater than the preset transparency and there is no damaged area, determining that the characteristic type of the tourmaline is the first characteristic type;

[0017] If the transparency of the tourmaline is less than or equal to the preset transparency and there is a damaged area, it is determined that the characteristic type of the tourmaline is the second characteristic type.

[0018] Furthermore, the step of selecting tourmaline that meets the conditions for preparing raw materials by light analysis method includes:

[0019] Place the tourmaline on a platform with a white background, and shine the light at different angles on the tourmaline;

[0020] Use a colorimeter to measure and record the chromaticity values ​​of tourmaline at different angles;

[0021] Determining an average chromaticity value of the tourmaline based on the variance of the chromaticity values ​​of the tourmaline at different recorded angles;

[0022] The tourmaline whose average chromaticity value is less than the preset average chromaticity value is the tourmaline that meets the conditions for preparing raw materials.

[0023] Furthermore, the method of screening out tourmaline that meets the conditions for preparing raw materials by using the impurity content analysis method includes:

[0024] If the impurity content of the tourmaline is less than the preset impurity content, it is determined that the tourmaline is tourmaline that meets the conditions for preparing the raw material.

[0025] Further, the adjusting of the crushing parameters or the preset average chromaticity value based on the type of the filtered material includes:

[0026] If the type of the filtered material after filtration is a valid filtering type, it is determined that the crushing parameters or the preset average chromaticity value are not adjusted;

[0027] If the type of the filtered object is an impurity filtered object type, determining to adjust the preset average chromaticity value by a first adjustment coefficient;

[0028] If the type of the filtered material is a tourmaline filtered material type, it is determined that the crushing parameters are adjusted using the second adjustment coefficient.

[0029] Further, determining the type of the filtered material includes:

[0030] If the remaining weight of the filtered material after filtration is less than the preset remaining weight, determining that the type of the filtered material is a valid filtering type;

[0031] If the remaining weight of the filtered material after filtration is greater than or equal to the preset remaining weight and the weight proportion of tourmaline is greater than the preset proportion, the type of the filtered material is determined to be a tourmaline filtered material type;

[0032] If the remaining weight of the filtered material after filtration is greater than or equal to the preset remaining weight and the weight proportion of tourmaline is less than or equal to the preset proportion, it is determined that the type of the filtered material is an impurity filtered material type.

[0033] Further, based on the solution state of the prepared negative ion liquid after shaking and the purification effect of the smoke removal test on the negative ion liquid, determining the adjustment coefficient of the crushing parameter or adjusting the tourmaline characteristic type judgment parameter includes:

[0034] If the solution state of the negative ion liquid after shaking is precipitation or agglomeration, determining to adjust the first adjustment coefficient;

[0035] If the solution state of the negative ion liquid after shaking is that there is no precipitation or agglomeration phenomenon and the purification effect of the smoke removal test on the negative ion liquid is unqualified, it is determined to adjust the preset residual weight.

[0036] Further, the steps of judging whether the purification effect of the smoke removal test on the negative ion liquid is qualified include:

[0037] Prepare a closed transparent container and light a cigarette or mosquito coil inside to produce smoke;

[0038] Put the negative ion liquid into the container and record the time when the smoke disappears;

[0039] If the time for the smoke to disappear is less than the preset time, it is judged that the purification effect of the smoke removal test using the negative ion liquid is qualified.

[0040] An apparatus adopting the process for preparing negative ion liquid extracted by tourmaline plants comprises:

[0041] A pulverizing device, which is used to pulverize tourmaline to obtain tourmaline powder;

[0042] A heating and stirring device, connected to the pulverizing device, for heating and stirring the tourmaline powder and hydrochloric acid to obtain a first mixed solution;

[0043] A filtering device, connected to the heating and stirring device, for filtering the first mixed solution;

[0044] A reaction kettle is connected to the filtering device and is used to mix the first mixed solution with the second mixed solution to obtain a negative ion liquid.

[0045] Compared with the prior art, the beneficial effect of the present invention is that the present invention adopts the light analysis method or the impurity content analysis method for screening according to the different characteristic types of tourmaline, and can more accurately select the tourmaline that meets the requirements as the preparation raw material. For the tourmaline of the first characteristic type, the tourmaline can be screened by the light analysis method to improve the screening efficiency. When the tourmaline belongs to the second characteristic type, the impurity content analysis method is adopted, which can accurately detect the impurity components and content in the tourmaline, and avoid the adverse effect on the performance of the negative ion liquid due to excessive impurities. Strictly controlling the impurity content helps to ensure that the negative ion liquid finally prepared meets the environmental protection and health and safety standards, and can also ensure the performance stability of the negative ion liquid, because impurities may interfere with the process of tourmaline releasing negative ions or react chemically with other raw materials. The screening method based on the characteristic type of tourmaline avoids the limitations that may be brought by a single screening method. Different screening methods are suitable for tourmalines of different characteristic types, and can quickly and effectively identify raw materials that do not meet the requirements, reducing unnecessary detection links. The above method improves the accuracy of the analysis of the preparation raw materials of the negative ion liquid extracted from the tourmaline plant, thereby improving the performance of the negative ion liquid.

[0046] Furthermore, the present invention adjusts the crushing parameters or presets the average chromaticity value according to the type of filter material, so as to more accurately control the processing process of tourmaline. When the filter material is an impurity filter material type, by adjusting the preset average chromaticity value, it is possible to better adapt to factors such as color differences that may exist in the tourmaline raw materials, which helps to more accurately judge the quality and performance of tourmaline in subsequent processes, because the chromaticity value reflects the purity and structural characteristics of tourmaline to a certain extent. For example, if the chromaticity value deviates greatly from the expected value, the subsequent process parameters can be made more in line with the actual situation through adjustment, thereby ensuring the stability of product quality. When the filter material is a tourmaline filter material type, the power of the crushing equipment is adjusted to optimize the crushing effect according to the actual situation of the tourmaline. Appropriate crushing power can make the tourmaline particles achieve an ideal size distribution, which is very important for improving the efficiency of tourmaline in the subsequent mixing and reaction process with other raw materials. For example, tourmaline particles that are crushed more evenly can increase the contact area with plant extracts, etc., promote the release of negative ions and the progress of reactions, and improve the quality and performance stability of negative ion liquids. The type of filter material is determined by the residual weight of the filter material and the weight proportion of tourmaline, which provides a scientific basis for process adjustment. When the residual weight of the filter material is less than the preset residual weight, it is determined to be an effective filter type, indicating that the current process (including preliminary treatments such as crushing) has a good effect in removing impurities and other aspects. There is no need to adjust the parameters, and the original process can be continued to ensure the continuity and stability of production. When the residual weight is large and it is judged to be a tourmaline filter material type or an impurity filter material type according to the weight proportion of tourmaline, the crushing parameters or the preset average chromaticity values ​​are adjusted respectively, which can solve possible problems in a targeted manner. For example, if the weight proportion of tourmaline is too large, it means that the crushing effect may not be ideal and the crushing power needs to be adjusted; if the weight proportion of impurities is too large, adjusting the preset average chromaticity value can better adapt to this situation, so that corresponding measures can be taken in subsequent processes, such as further optimizing the impurity removal steps, etc., thereby improving the overall quality of the product; the above method improves the accuracy of the analysis of the preparation raw materials of the negative ion liquid extracted from tourmaline plants, thereby improving the performance of the negative ion liquid.

[0047] Furthermore, the present invention adjusts parameters according to the solution state of the negative ion liquid after shaking and the purification effect of the smoke removal test, which can optimize the preparation process more accurately. When there is precipitation or agglomeration in the solution state, the first adjustment coefficient is adjusted with the third adjustment coefficient, which helps to solve the problem of uneven dispersion of tourmaline in the negative ion liquid and improve the stability of the solution. For example, the adjusted first adjustment coefficient may affect the preset average chromaticity value, thereby affecting the judgment of the tourmaline quality and subsequent process adjustments, so that the tourmaline can be better mixed with other ingredients in subsequent processing, reducing the occurrence of precipitation and agglomeration. When the solution state is good but the purification effect of the smoke removal test is unqualified, the preset residual weight is adjusted with the fourth adjustment coefficient, which can prompt more stringent control of the impurity content in the filtration link, thereby improving The purification performance of the negative ion liquid, for example, the adjusted preset residual weight may make the filtration standard more stringent, further remove impurities that may affect the purification effect, and thus improve the performance of the negative ion liquid in practical applications such as smoke removal tests. The two indicators of solution state and smoke removal test are used to determine whether to adjust the parameters, which can comprehensively evaluate the quality of the negative ion liquid. If only relying on a single indicator, there may be misjudgment or failure to accurately reflect the product performance. By comprehensively considering the physical state of the solution and the actual purification effect, it is possible to more accurately judge whether the product meets the quality requirements, so as to adjust the process parameters in time to ensure that each batch of negative ion liquid has stable quality. For example, even if there is no precipitation or agglomeration in the appearance of the solution, if the purification effect is unqualified, it means that there may be some potential problems in the preparation process, which need to be solved by adjusting the parameters to ensure the stability of the product performance in actual use; the above method improves the accuracy of the analysis of the preparation raw materials of the negative ion liquid extracted from the tourmaline plant, thereby improving the performance of the negative ion liquid.

[0062] Step S5, determining whether to adjust the adjustment coefficient of the crushing parameter or the tourmaline characteristic type judgment parameter based on the solution state of the prepared negative ion liquid after shaking and the purification effect of the smoke removal test on the negative ion liquid.

[0063] The characteristic data of the tourmaline in the embodiment of the present invention include but are not limited to "shape, transparency and roughness"; the tourmaline can be selected from tourmaline and monazite, and the plant can be selected from aloe vera. The mixing, stirring and grinding of the tourmaline that meets the raw material preparation conditions with 60% sodium hydroxide solution to obtain a slurry includes grinding the tourmaline and monazite to 400 mesh, mixing and stirring with infrared mineral powder and other tourmalines at a weight ratio of 15-20:50-70:10-20, adding 60% NaOH (sodium hydroxide) to the stirred mixture at a weight ratio of 1.5-2.5:1, putting the mixture into a wet ball mill for two grindings to make the grinding particle size reach 0.8 microns to obtain a slurry, adding hydrochloric acid to the slurry to obtain a first mixture, heating and stirring the first mixture for a first preset time, and filtering to obtain a first mixed solution includes adding 20% ​​hydrochloric acid (hydrochloric acid concentration is 6mo l / L), then add hydrogen peroxide with a weight ratio of 20% and a concentration of 30% to 35%, stir at a speed of 200 rpm, stir for 1 hour (first preset time), and filter the stirred first mixture to obtain a first mixed solution. In the embodiment of the present invention, in step S3, the mass ratio of plant to water is 2:8, the temperature is adjusted to 90°C for heating, the stirring time is 2 hours (second preset time), and the plant extract is extracted when the temperature is reduced to 30°C.

[0064] Specifically, in step S1, when the tourmaline that meets the conditions for preparing the raw material is screened out, the tourmaline that meets the conditions for preparing the raw material is screened out by a light analysis method or an impurity content analysis method according to the characteristic type of the tourmaline;

[0065] When the characteristic type of the tourmaline is the first characteristic type, determining to screen out the tourmaline that meets the conditions for preparing the raw material by the light analysis method;

[0066] When the characteristic type of the tourmaline is the first characteristic type, it is determined that the tourmaline that meets the conditions for preparing the raw material is screened out by the impurity content analysis method.

[0067] Specifically, in step S1, when judging the characteristic type of tourmaline, the characteristic type of tourmaline is determined according to the transparency of the tourmaline and whether there is a damaged area of ​​the tourmaline;

[0068] When the transparency of the tourmaline is greater than a preset transparency and there is no damaged area, determining that the characteristic type of the tourmaline is a first characteristic type;

[0069] When the transparency of the tourmaline is less than or equal to the preset transparency and there is a damaged area, determining that the characteristic type of the tourmaline is the second characteristic type;

[0070] Among them, the preset transparency value is the average transparency of tourmaline in the historical record of negative ion liquid preparation, but the above value is not limited to this, and technicians in this field can also adjust the value according to actual needs.

[0071] Specifically, in step S1, the step of selecting tourmaline that meets the conditions for preparing raw materials by light analysis method includes:

[0072] Place the tourmaline on a platform with a white background, and shine the light at different angles on the tourmaline;

[0073] Use a colorimeter to measure and record the chromaticity values ​​of tourmaline at different angles;

[0074] Determining an average chromaticity value of the tourmaline based on the variance of the chromaticity values ​​of the tourmaline at different recorded angles;

[0075] The tourmaline whose average chromaticity value is less than the preset average chromaticity value is the tourmaline that meets the conditions for preparing raw materials.

[0076] In the embodiment of the present invention, the light source is irradiated on the tourmaline at different angles, including taking the center point of the tourmaline as a reference point, rotating 360 degrees horizontally and 360 degrees vertically. The colorimeter is used to measure and record the chromaticity value of the tourmaline at different angles, including recording the chromaticity value of the tourmaline at intervals of 15 degrees. The preset average chromaticity value is the historical average value of the average chromaticity value of tourmaline in the history record of the preparation of negative ion liquid. However, the above value is not limited to this, and technicians in this field can also adjust the value according to actual needs.

[0077] Specifically, in step S1, when it is determined that the tourmaline that meets the conditions for preparing the raw material is screened out by the impurity content analysis method, the tourmaline that meets the conditions for preparing the raw material is screened out according to the comparison result between the impurity content of the tourmaline and the preset impurity content;

[0078] When the impurity content of the tourmaline is less than the preset impurity content, determining that the tourmaline is tourmaline that meets the conditions for preparing the raw material;

[0079] When the impurity content of the tourmaline is greater than or equal to the preset impurity content, it is determined that the tourmaline is not tourmaline that meets the conditions for preparing the raw material;

[0080] Among them, the preset impurity content value is the average value of the impurity content of tourmaline in the historical record of negative ion liquid preparation, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0081] The present invention adopts an illumination analysis method or an impurity content analysis method for screening according to different characteristic types of tourmaline, and can more accurately select tourmaline that meets the requirements as a preparation raw material. For tourmaline of the first characteristic type, the tourmaline can be screened by the illumination analysis method to improve the screening efficiency. When the tourmaline belongs to the second characteristic type, the impurity content analysis method is adopted, which can accurately detect the impurity components and content in the tourmaline, and avoid the adverse effects on the performance of the negative ion liquid due to excessive impurities. Strictly controlling the impurity content helps to ensure that the negative ion liquid finally prepared meets environmental protection and health and safety standards, and can also ensure the performance stability of the negative ion liquid, because impurities may interfere with the process of tourmaline releasing negative ions or react chemically with other raw materials. The screening method based on the characteristic type of tourmaline avoids the limitations that may be brought by a single screening method. Different screening methods are suitable for tourmalines of different characteristic types, and can quickly and effectively identify raw materials that do not meet the requirements, reducing unnecessary detection links. The above method improves the accuracy of the analysis of the preparation raw materials of the negative ion liquid extracted from the tourmaline plant, thereby improving the performance of the negative ion liquid.

[0082] Specifically, in step S2, when it is determined to adjust the crushing parameter or the preset average chromaticity value, it is determined to adjust the crushing parameter or the preset average chromaticity value according to the type of the filtered material;

[0083] When the type of the filtered product is a valid filtering type, determining not to adjust the crushing parameter or the preset average chromaticity value;

[0084] When the type of the filtered object is an impurity filtered object type, determining to adjust the preset average chromaticity value by a first adjustment coefficient;

[0085] When the type of the filtered material is a tourmaline filter material type, it is determined that the pulverizing parameter is adjusted with the second adjustment coefficient.

[0086] In the embodiment of the present invention, the value range of the first adjustment coefficient is set to 0.85-0.97, the value range of the second adjustment coefficient is set to 1.05-1.21, and the crushing parameter is the power of the crushing equipment for crushing tourmaline, but the above values ​​are not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0087] Specifically, in step S2, when determining the type of the filtered material, the type of the filtered material is determined according to the remaining weight of the filtered material and the weight proportion of the tourmaline;

[0088] When the remaining weight of the filtered material is less than the preset remaining weight, determining the type of the filtered material to be an effective filtering type;

[0089] When the remaining weight of the filtered material is greater than or equal to the preset remaining weight and the weight proportion of tourmaline is greater than the preset proportion, the type of the filtered material is determined to be a tourmaline filtered material type;

[0090] When the remaining weight of the filtered material is greater than or equal to the preset remaining weight and the weight proportion of tourmaline is less than or equal to the preset proportion, the type of the filtered material is determined to be an impurity filtered material type.

[0091] The preset residual weight in the embodiment of the present invention is the historical average value of the residual weight of the filtrate in the historical process of preparing the negative ion liquid. The value range of the preset proportion is set to 0.8-1, and the value of the preset proportion is preferably 0.87, but the above value is not limited to this. Technical personnel in this field can also adjust the value according to actual needs.

[0092] The present invention adjusts the crushing parameters or presets the average chromaticity value according to the type of the filter, and can more accurately control the processing process of tourmaline. When the filter is an impurity filter type, by adjusting the preset average chromaticity value, it can better adapt to factors such as color differences that may exist in the tourmaline raw materials, which helps to more accurately judge the quality and performance of tourmaline in subsequent processes, because the chromaticity value reflects the purity and structural characteristics of tourmaline to a certain extent. For example, if the chromaticity value deviates greatly from the expectation, the subsequent process parameters can be made more in line with the actual situation by adjustment, thereby ensuring the stability of product quality. When the filter is a tourmaline filter type, the power of the crushing equipment is adjusted, and the crushing effect can be optimized according to the actual situation of the tourmaline. The appropriate crushing power can make the tourmaline particles reach an ideal size distribution, which is very important for improving the efficiency of tourmaline in the subsequent mixing and reaction process with other raw materials. For example, tourmaline particles that are crushed more evenly can increase the contact area with plant extracts, etc., promote the release of negative ions and the progress of the reaction, and improve the quality and performance stability of the negative ion liquid. The type of filter is determined by the residual weight of the filter and the weight proportion of tourmaline, which provides a scientific basis for process adjustment. When the residual weight of the filter is less than the preset residual weight, it is determined to be an effective filter type, indicating that the current process (including preliminary treatments such as crushing) is effective in removing impurities and other aspects. There is no need to adjust the parameters and the original process can be continued to ensure the continuity and stability of production. When the residual weight is large and it is judged to be a tourmaline filter type or an impurity filter type based on the weight proportion of tourmaline, the crushing parameters or the preset average chromaticity values ​​are adjusted respectively, which can solve possible problems in a targeted manner. For example, if the weight proportion of tourmaline is too large, it means that the crushing effect may not be ideal and the crushing power needs to be adjusted; if the weight proportion of impurities is too large, adjusting the preset average chromaticity value can better adapt to this situation, so that corresponding measures can be taken in subsequent processes, such as further optimizing the impurity removal steps, thereby improving the overall quality of the product; the above method improves the accuracy of the analysis of the preparation raw materials of the negative ion liquid extracted from tourmaline plants, thereby improving the performance of the negative ion liquid.

[0093] Specifically, in step S5, when determining the adjustment coefficient of the crushing parameter or adjusting the characteristic type judgment parameter of the tourmaline, the adjustment coefficient of the crushing parameter or adjusting the characteristic type judgment parameter of the tourmaline is determined according to the solution state of the prepared negative ion liquid after shaking and the purification effect of the smoke removal test;

[0094] When the solution state of the negative ion liquid after shaking is precipitation or agglomeration, determining to adjust the first adjustment coefficient by a third adjustment coefficient;

[0095] When the solution state of the negative ion liquid after shaking is that there is no precipitation or agglomeration phenomenon and the purification effect of the smoke removal test on the negative ion liquid is unqualified, determining to adjust the preset residual weight by a fourth adjustment coefficient;

[0096] When the solution state of the negative ion liquid after shaking is that there is no precipitation or agglomeration phenomenon and the purification effect of the smoke removal test on the negative ion liquid is qualified, it is determined not to adjust the adjustment coefficient of the crushing parameter or the tourmaline characteristic type judgment parameter.

[0097] In the embodiment of the present invention, the value range of the third adjustment coefficient is set to 0.81-0.96, and the value range of the fourth adjustment coefficient is set to 1.04-1.19, but the above values ​​are not limited thereto, and those skilled in the art may also adjust the values ​​according to actual needs.

[0098] Specifically, in step S5, the step of judging whether the purification effect of the smoke removal test on the negative ion liquid is qualified includes:

[0099] Step S5501, prepare a closed transparent container, light a cigarette or mosquito coil in it to generate smoke;

[0100] Step S5502, putting negative ion liquid into a container and recording the time when the smoke disappears;

[0101] Step S5503: If the time for smoke to disappear is less than the preset disappearance time, it is determined that the purification effect of the smoke removal test using the negative ion liquid is qualified.

[0102] The value of the preset hour time in the embodiment of the present invention is the historical average value of the smoke hour time when the same weight of negative ion liquid is used for smoke removal test, but the above value is not limited to this, and technicians in this field can also adjust the value according to actual needs.

[0103] The present invention adjusts parameters according to the solution state of the negative ion liquid after shaking and the purification effect of the smoke removal test, and can optimize the preparation process more accurately. When there is precipitation or agglomeration in the solution state, the first adjustment coefficient is adjusted with the third adjustment coefficient, which helps to solve the problem of uneven dispersion of tourmaline in the negative ion liquid and improve the stability of the solution. For example, the adjusted first adjustment coefficient may affect the preset average chromaticity value, thereby affecting the judgment of the tourmaline quality and subsequent process adjustments, so that the tourmaline can be better mixed with other ingredients in subsequent processing, reducing the occurrence of precipitation and agglomeration. When the solution state is good but the purification effect of the smoke removal test is unqualified, the preset residual weight is adjusted with the fourth adjustment coefficient, which can prompt more stringent control of the impurity content in the filtration link, thereby improving The purification performance of the negative ion liquid, for example, the adjusted preset residual weight may make the filtration standard more stringent, further remove impurities that may affect the purification effect, and thus improve the performance of the negative ion liquid in practical applications such as smoke removal tests. The two indicators of solution state and smoke removal test are used to determine whether to adjust the parameters, which can comprehensively evaluate the quality of the negative ion liquid. If only relying on a single indicator, there may be misjudgment or failure to accurately reflect the product performance. By comprehensively considering the physical state of the solution and the actual purification effect, it is possible to more accurately judge whether the product meets the quality requirements, so as to adjust the process parameters in time to ensure that each batch of negative ion liquid has stable quality. For example, even if there is no precipitation or agglomeration in the appearance of the solution, if the purification effect is unqualified, it means that there may be some potential problems in the preparation process, which need to be solved by adjusting the parameters to ensure the stability of the product performance in actual use; the above method improves the accuracy of the analysis of the preparation raw materials of the negative ion liquid extracted from the tourmaline plant, thereby improving the performance of the negative ion liquid.
