Embodiment 1

[0050] This embodiment provides a method for measuring the amount of purification of the filter screen, for example, it can be used to measure the purification amount of the filter screen of the air purification equipment, such as figure 1 As shown, the method may include:

[0051] S11: Obtain the concentration of substances in the air within the current time period and the actual air volume passing through the filter, the actual air volume is obtained according to the theoretical air volume and the accumulated purification volume of the filter before the current time period.

[0052] In this embodiment, the substance concentration in the air can be obtained by measuring the substance concentration sensor, and the substance concentration sensor is arranged at the air inlet before the filter screen to ensure the accuracy of the measurement data. The theoretical air volume can be obtained by using conventional air volume measurement methods in the prior art, for example, by sett...

Embodiment 2

[0074] Such as image 3 As shown, the present embodiment provides a method for determining the service life of the filter screen, including:

[0075] S21: Obtain the cumulative purification amount of the filter according to the metering method of the purification amount of the filter described in Embodiment 1;

[0076] S22: Judging whether the difference between the theoretical purification amount of the filter screen and the accumulated purification amount of the filter screen is less than a predetermined threshold, when the difference between the theoretical purification amount of the filter screen and the cumulative purification amount of the filter screen When the value is less than the predetermined threshold, step S23 is executed, and when the difference between the theoretical purification amount of the filter and the accumulated purification amount of the filter is not less than the predetermined threshold, step S24 is executed.

[0077] In step S23: it is determined ...

Embodiment 3

[0082] Such as Figure 4 As shown, the present embodiment provides a metering device for the amount of purification of the filter screen, including:

[0083] Concentration and air volume acquisition unit 41, used to acquire the concentration of substances in the air within the current time period and the actual air volume passing through the filter screen, the actual air volume is based on the theoretical air volume and the accumulation of the filter screen before the current time period The purification amount is obtained, for details, please refer to the description of step S11 in Example 1;

[0084] The purification amount acquisition unit 42 is used to obtain the purification amount of the current time period according to the concentration of substances in the air in the current time period and the actual air volume, for details, please refer to the description of step S12 in Embodiment 1;

[0085] The summing unit 43 is configured to sum the purification amount in the cu...

Abstract

The invention relates to the technical field of gas metering, in particular to a measuring method and device for the purification amount of a filter net, a method and device for determining the service life of a filter net, an air purification device and a non-transient computer readable storage medium. The measuring method of the purification amount of a filter net includes obtaining the substance concentration of the air in the current time period and the actual air volume through the filter net, wherein the actual air volume is obtained according to the theoretical air volume and the accumulative purification amount of the filter net before the current time period; obtaining the purification amount of the current time period according to the substance concentration of the air in the current time period and the actual air volume; and summing up the purification amount of the current time period and the accumulative purification amount before the current time period. The error of theactual air volume value caused by the filter net pollutant filling can be avoided, and the purification amount of the filter net can be calculated accurately.

Description

technical field [0001] The invention relates to the technical field of gas metering, in particular to a method and device for measuring the purification amount of a filter screen, a method and device for determining the service life of a filter screen, air purification equipment, and a non-transient computer-readable storage medium. Background technique [0002] At present, for air purification equipment, the existing air purification equipment generally uses filters to purify the air. These filters have a certain service life. After the air purification equipment is used for a certain period, the filter will gradually be filtered from the air. When the pollutants are full, the life of the filter screen is over. If it is used again, the filter screen will lose its air purification performance. At this time, the filter screen needs to be replaced. [0003] As for when to replace the filter screen, some filters have a fixed life, for example, the preset life of the filter scre...
