Detailed Description

For a more complete understanding of the features and technical content of the embodiments of the present application, reference should be made to the following detailed description of the embodiments of the present application, taken in conjunction with the accompanying drawings, which are for purposes of illustration only and not intended to limit the embodiments of the present application.

The embodiment of the application provides a control method of a purification device for solving the problem that the air purification rate of the existing purification device is low, and the purification device can have the functions of sterilizing, purifying air, removing formaldehyde, deodorizing and the like. As shown in fig. 1, the purification apparatus may include a photocatalytic module including: the photocatalyst filter screen 11, the ultraviolet lamp 12, the control circuit 13 and the driving power supply 14, the photocatalyst module is located in the air duct 15 of the purifying device, and can be located in an air inlet duct or an air outlet duct, the purifying device further comprises a fan (not shown in fig. 1), working driving air passes through the photocatalyst filter screen 11 from the air duct 15, the ultraviolet lamp 12 irradiates the photocatalyst filter screen 11 to form electron-hole pairs, the electron-hole pairs react with water molecules and oxygen molecules in the air to generate hydroxyl free radicals and superoxide ion free radicals with strong oxidizing property, and the purposes of purifying and removing peculiar smell are achieved.

Fig. 2 is a schematic flow chart of a control method of a purification apparatus according to an embodiment of the present application, and as shown in fig. 2, the method may specifically include:

step 201: acquiring current environmental parameters;

here, the environmental parameter is a parameter for indicating different environmental states. Illustratively, the current environmental parameters include humidity and/or organic concentration.

The influence of humidity on the purification rate, when the purification device works, ultraviolet light irradiates the photocatalyst to form electron-hole pairs, the electron-hole pairs react with surrounding water molecules and oxygen molecules to generate hydroxyl free radicals and superoxide ion free radicals with strong oxidability, the humidity is increased, the survival time of active oxygen is prolonged, and the purification rate is improved.

Fig. 3 is a schematic diagram of the correspondence between humidity and the amount of active oxygen in the embodiment of the present application, as shown in fig. 3, when the humidity is between 30% and 90%, the amount of active oxygen increases with the increase of humidity. The electron-hole pairs react with water and oxygen to form active oxygen, and the amount of active oxygen can be increased by increasing the humidity.

Fig. 4 is a schematic diagram showing a correspondence relationship between humidity and active oxygen survival time in the embodiment of the present application, and as shown in fig. 4, when the humidity is between 30% and 90%, the active oxygen survival time increases with the increase of the humidity. That is, the humidity increases and the active oxygen survival time increases.

Fig. 5 is a schematic diagram of the correspondence between humidity and formaldehyde purification rate in the embodiment of the present application, and as shown in fig. 5, when the humidity is between 30% and 90%, the formaldehyde purification rate increases with the increase of the humidity.

Thus, the operating parameters of the purification device can be adjusted according to the humidity of the current environment. For example, when the humidity is within the optimal humidity range, the power of the ultraviolet lamp can be appropriately reduced, and although the amount of active oxygen is reduced, the survival time of the active oxygen is increased, and the energy consumption is reduced while the purification rate is ensured.

The effect of organic concentration on the purification rate, the photocatalytic degradation rate can be expressed by the Langmuir-Hinshelwood kinetic equation: r= kKc/(1+kc), where R is the degradation rate; k is a rate constant; k is an adsorption constant; c is the organic concentration. Kc is much greater than 1 when the organic concentration is high, r=k; when the organic concentration is very low, r= kKc, the degradation rate is proportional to the organic concentration. Here, the higher the degradation rate, the higher the purge rate, and in general, the concentration of the organic matter has a monotonically increasing relationship with the degradation rate, as shown in fig. 6.

Therefore, the working parameters of the purifying device can be adjusted according to the concentration of the organic matters in the current environment, and when the concentration of the organic matters is in the optimal concentration range, the degradation rate is higher, namely the purifying rate is higher, the ultraviolet lamp power is kept unchanged, or the ultraviolet lamp power is properly reduced. When the concentration of the organic matters is low, the degradation rate is low, and the power of the ultraviolet lamp can be properly increased to ensure the purification rate, so that the irradiation intensity of the ultraviolet lamp on the photocatalyst filter screen is enhanced, and the degradation rate, namely the purification rate, is improved.

Illustratively, in alternative embodiments, the current environmental parameters further include temperature, pH, and the like.

Step 202: determining a target operating parameter of the purification device based on a preset operating parameter, a current environmental parameter and a current purification space parameter of the purification device;

here, the preset operating parameter may be a default operating parameter of the purification apparatus, or a historical operating parameter. The working parameters are parameters influencing the catalytic effect of the photocatalytic module in the purification device, and adjusting the working parameters can be understood as adjusting the catalytic effect, i.e. adjusting the purification efficiency.

After the purification device is started, the preset working parameters can be adaptively adjusted according to the current environment parameters and the current purification space parameters to obtain target working parameters matched with the current environment and the purification space, the target working parameters can be understood as the optimal working parameters of the purification device in the current environment, and the balance of the purification rate and the energy consumption can be realized under the optimal working parameters.

For example, the current clean space parameter may be a parameter related to the current clean space size. The larger the purge space, the more power of the ultraviolet lamp may be appropriately increased in order to ensure the purge rate, whereas the smaller the purge space, the more power of the ultraviolet lamp may be appropriately decreased in order to ensure the purge rate.

The current clean room parameter may be a parameter related to the current clean room demand. The higher the purification requirement of the purification space, the power of the ultraviolet lamp can be properly increased to ensure the purification rate, whereas the smaller the purification requirement, the power of the ultraviolet lamp can be properly reduced to ensure the purification rate.

For example, the parameters of the purifying space may be fixed parameters set in advance or may be set by the user according to the actual purifying space.

Illustratively, in some embodiments, the method further comprises: presetting corresponding relations among preset working parameters, current environment parameters, current purification space parameters and target working parameters, and determining the target working parameters based on the corresponding relations. The corresponding relation can be embodied in the form of an adjusting function, or can be a corresponding relation table established on the basis of the adjusting function and stored, and the corresponding target working parameters are searched in a table look-up mode.

The method includes the steps that an adjustment condition can be set according to an environment parameter, and when the current environment parameter meets the adjustment condition, the preset working parameter is characterized to be adjusted; and when the characteristic is not satisfied, the characteristic does not need to adjust the preset working parameters.

Step 203: and controlling the operation target working parameters of the purifying device.

Here, the purification device comprises at least one component, and the operating parameters comprise operating parameters of the at least one component, a change in the operating parameters of which affects the purification rate. That is to say, the method specifically comprises the following steps: and controlling corresponding working parameters in the target working parameters of at least one component in the purifying device.

Illustratively, the purifying apparatus includes a blower and an ultraviolet lamp, and the operating parameters include: fan speed and uv lamp power.

Here, the higher the fan rotational speed, the greater the wind speed in the purification channel, showing that the faster the air passes through the purification channel, the higher the purification rate can be improved by accelerating the air flow rate when the humidity and the organic matter concentration are lower, otherwise, the purification rate is kept at a higher level when the humidity and the organic matter concentration are higher, and the air flow rate can be reduced to save energy consumption.

The higher the ultraviolet lamp power is, the higher the purification rate is, the purification rate is improved by improving the ultraviolet lamp power to enhance the irradiation intensity of the ultraviolet lamp to the photocatalyst filter screen when the humidity and the organic matter concentration are lower, otherwise, the purification rate is kept at a higher level when the humidity and the organic matter concentration are higher, and the ultraviolet lamp power can be reduced to save energy consumption.

By adopting the technical scheme, according to external uncontrollable environmental parameters, the rotating speed of the fan and the power of the ultraviolet lamp in the purifying device are flexibly adjusted, so that the purifying device can keep stable purifying rate under different environmental conditions, and especially when the environmental quality is good, the stable purifying rate is kept, and meanwhile, the energy consumption can be reduced.

To further illustrate the present application, based on the foregoing embodiments of the present application, as shown in fig. 7, the method specifically includes:

step 701: acquiring current environmental parameters;

step 702: when the current environmental parameters meet preset adjustment conditions, determining an adjustment function corresponding to the adjustment conditions;

for example, in some embodiments, the method further includes presetting a correspondence between a plurality of adjustment conditions and adjustment functions, determining a target adjustment condition that is satisfied by the current environmental parameter, and determining a target adjustment function corresponding to the target adjustment condition based on the correspondence.

Here, the preset working parameter, the current environmental parameter and the current clean space parameter in the adjustment function are taken as the known quantity, the target working parameter is taken as the unknown quantity, and the known quantity is calculated by utilizing the known quantity.

In practical applications, when the operating parameters include operating parameters of a plurality of components in the purifying device, the adjusting function may include an adjusting function corresponding to each component. Exemplary operating parameters include: fan speed and ultraviolet lamp power; the adjusting function includes: a first function for adjusting the fan speed, and a second function for adjusting the ultraviolet lamp power.

Illustratively, in some embodiments, the operating parameters include: fan speed and ultraviolet lamp power; the first function includes: and obtaining an adjustment value by using the current environment parameter and the current purified space parameter, and adding the preset fan rotating speed and the adjustment value to obtain the adjusted fan rotating speed. Specifically, the expression of the first function is: w' =w+f (x, y), wherein W is a preset fan rotation speed, x is humidity, y is an organic concentration, f (·) represents a relationship between xy and an adjustment value, and f (·) further includes a purification space parameter.

The second function includes: and obtaining an adjustment coefficient by using the preset fan rotating speed, the current environment parameter and the current purification space parameter, and multiplying the preset ultraviolet lamp power by the adjustment coefficient to obtain the adjusted ultraviolet lamp power. Specifically, the expression of the second function is: r' =r×f (x, y), where R is preset ultraviolet lamp power, x is humidity, y is organic concentration, f (·) represents the relationship between xy and adjustment coefficient, and f (·) further includes a purification space parameter and a preset fan rotation speed. In practical applications, f (·) is set in different adjustment functions.

Step 703: substituting the current environmental parameter, the preset working parameter of the purification device and the current purification space parameter into an adjustment function to obtain a target working parameter;

exemplary operating parameters include: substituting a preset fan rotating speed, a current environment parameter and a current purification space parameter into a first function to obtain an adjusted fan rotating speed; substituting the preset fan rotating speed, the preset ultraviolet lamp power, the current environment parameter and the current purification space parameter into a second function to obtain the adjusted ultraviolet lamp power.

Step 704: and controlling the operation target working parameters of the purifying device.

In some embodiments, the method further comprises: and when the humidity is smaller than the first threshold value, controlling the humidifier to execute a humidifying operation so as to adjust the humidity in the purifying channel. By way of example, the atomization rate of the humidifier can also be controlled according to the ambient humidity, so that the purified ambient humidity is maintained in an optimal humidity range, and thus the amount of active oxygen generated in the purification process is high, the survival time is long, the amount of generated ozone is low, and a high purification rate is maintained.

To further illustrate the present application, based on the foregoing embodiments of the present application, as shown in fig. 8, the method specifically includes:

Step 803: judging whether the humidity x is less than 50; if so, go to step 804; if not, go to step 807;

here, 50 represents a humidity of 50%, that is, a first threshold value in the embodiment of the present application.

Step 804: judging whether the concentration y of the organic matters is less than 0.8; if so, go to step 805; if not, go to step 806;

here, 0.8 means that the organic matter concentration is 0.8ppm, that is, the second threshold value in the embodiment of the present application.

Step 805: the first function is: w+50a/x+0.8a/y, the second function being R (1+50a/xW+0.8a/yW);

Wherein, W and R are the initial power of the ultraviolet lamp and the initial wind speed of the fan respectively, and the increased or decreased power and wind speed are within 25% of the preset values. The coefficient a is a parameter related to the size of the odor removal space, and the value range of the coefficient a is 0-1. And (5) timing the time to shut down the purification device.

Step 807: judging whether the concentration y of the organic matters is less than 0.8; if so, go to step 808; if not, go to step 809;

step 808: the first function is: w-50a/x+0.8a/y, the second function is R (1-50 a/xW+0.8a/yW);

specifically, a purification device is started, the humidity and the concentration of organic matters are detected and recorded as x and y respectively, and when the humidity is more than or equal to 50%; when the concentration of organic matters is less than 0.8ppm, the output power of the ultraviolet lamp is adjusted to be: w-50a/x+0.8a/y; the rotating speed of the fan is adjusted as follows: r (1-50 a/xW+0.8a/yW).

Step 809: the first function is: w-50a/x-0.8a/y, the second function is R (1-50 a/xW-0.8 a/yW);

specifically, a purification device is started, the humidity and the concentration of organic matters are detected and recorded as x and y respectively, and when the humidity is more than or equal to 50%; when the concentration of the organic matters is more than or equal to 0.8ppm, the output power of the ultraviolet lamp is adjusted to be: w-50a/x-0.8a/y; the rotating speed of the fan is adjusted as follows: r (1-50 a/xW-0.8 a/yW).
