Next, a brief description will be given of the background of the present invention.
For the filter element of the air purification device, the filter element is generally applied to air purifiers, fresh air blowers and fresh air purifier air filtering equipment. The filter element of the air purification device filters, adsorbs and decomposes particulate matters and harmful gases in the air. When air enters the filter element with a filter screen of a certain specification, specific pollutants are filtered, adsorbed and decomposed, and clean air flows out through the filter element.
Since the filter element is a consumable material, the service life of the filter element may reach a limit after the filter element is continuously operated for a period of time, and the filter element needs to be replaced at the moment so as to ensure that the purifying equipment can normally complete the purifying operation. However, in the related art, only the working time of the filter element is considered, and the influence of the quality factor of the ambient air where the filter element is located on the service life of the filter element is not considered, so that the calculated service life has errors.
Based on this, the inventors of the present invention have devised a method and a device for calculating the lifetime of a filter element of an air cleaning apparatus as described below.
Next, a method of calculating the lifetime of a filter element of an air cleaning device according to an embodiment of the present invention will be described with reference to fig. 2.
As shown in fig. 2, a method S100 for calculating a service life of a filter element of an air purification apparatus includes:
s110, acquiring real-time accumulated purification amount of the filter element and target accumulated purification amount of the filter element when the filter element reaches a clean air residual amount threshold value, and calculating the first service life of the filter element according to the real-time accumulated purification amount and the target accumulated purification amount.
Specifically, in this step, the real-time accumulated purification amount of the filter element may be obtained through real-time collection, and of course, in addition, the real-time accumulated purification amount of the filter element may also be automatically obtained through a computer program, and may specifically be determined according to actual needs, which is not limited in this embodiment. The threshold of the remaining amount of clean air is not specifically defined, and as a common example, the threshold of the remaining amount of clean air may be 50% of an initial value, that is, the target accumulated purification amount is an accumulated purification amount when the amount of clean air is attenuated to 50% of the initial value, and of course, besides, a person skilled in the art may select some other thresholds of the remaining amount of clean air according to actual needs, the target accumulated purification amount may be directly obtained according to parameters of accumulated purification capacity of the purifier for target pollutants (particulate matters and gaseous pollutants) under a rated state and a specified test condition, and of course, in addition, the target accumulated purification amount may be calculated in some other manners, which is not limited in this embodiment. After the real-time accumulated purification amount and the target accumulated purification amount of the filter element are obtained, the first life of the filter element can be calculated according to the real-time accumulated purification amount and the target accumulated purification amount.
And S120, acquiring the accumulated working time of the filter element and the replacement reference time of the filter element, and calculating the second service life of the filter element according to the accumulated working time and the replacement reference time.
And S130, performing weighted accumulation on the first service life and the second service life, and calculating to obtain the final service life of the filter element.
Specifically, in this step, the respective weights of the first life and the second life of the filter element calculated in step S110 and step S120 may be different, the weight ratio may be selected according to the equipment operating environment, and when both are set to 50%, it indicates that the weight of the filter element affected by the pollutant adsorption weight and the operating time is the same. In addition, when the weight of the first life is greater than the weight of the second life, it indicates that the pollutant adsorption weight of the filter element has a greater influence on the life of the filter element. Conversely, when the weight of the second life is greater than the weight of the first life, it indicates that the cumulative operating time of the filter element has a greater effect on the life of the filter element
According to the method for calculating the service life of the filter element, firstly, the first service life of the filter element is calculated according to the real-time accumulated purification amount and the target accumulated purification amount of the filter element, secondly, the second service life of the filter element is calculated according to the accumulated working time and the replacement reference time of the filter element, and finally, the first service life and the second service life are subjected to weighted accumulation to calculate the final service life of the filter element And decreases.
In some optional embodiments, the obtaining the target cumulative purification amount of the filter element when the threshold value of the residual amount of the clean air is reached comprises:
and acquiring a plurality of test accumulated purification amounts corresponding to a plurality of test residual amounts of the clean air respectively reached by the filter element, preferably, each test residual amount of the clean air is greater than the threshold value of the residual amount of the clean air.
And establishing a functional relation between the residual quantity of the clean air and the accumulated purification quantity according to the test residual quantities of the clean air and the corresponding test accumulated purification quantities.
And calculating to obtain the target accumulated purification amount according to the clean air residual amount threshold and the function relation.
Specifically, in obtaining the target accumulated purification amount of the filter element, the total mass of the target contaminants accumulated in the purification process when the amount of the clean air decays to 50% of the initial value is generally required to be the target accumulated purification amount. However, in practice, the enterprises cannot reduce the amount of clean air detected by the filter elements in all the purification apparatuses to 50% of the initial value due to the cost and time, and the detection is stopped as long as the standard requirement is met.
For the above reasons, the inventors of the present invention have originally proposed a method of estimating the target cumulative purge amount. That is, the accumulated purification amounts corresponding to the test residual amounts of the clean air in the filter element can be obtained, a functional relation between the accumulated purification amounts and the test residual amounts of the clean air can be established, and then the threshold value (for example, 50%) of the residual amounts of the clean air is substituted into the functional relation, so that the target accumulated purification amount can be estimated.
According to the method for calculating the service life of the filter element, the functional relation between the test surplus of the clean air and the corresponding test accumulated purification amount is established, so that the target accumulated purification amount is estimated according to the functional relation, the detection cost of acquiring the target accumulated purification amount by an enterprise can be effectively reduced, and the economic benefit is improved.
It should be understood that the above mentioned residual amount of clean air should be understood in a broad sense, and the residual amount of clean air may be a specific numerical value or a specific ratio, as shown in table 1 below, which is a relationship between the test accumulated clean amount and the test residual amount of clean air of a certain model.
In view of the above data, the inventors of the present invention have designed the fitting by a linear function, such as Q ═ a × M + b, and exemplarily, the present embodiment selects the linear function relation as follows:
q1000 is a M + b 1000, M is the cumulative purge amount, Q is the clean air test remaining amount, and the data in table 1 are substituted to calculate a-0.014, b is 1, and a functional relationship Q1000 is-0.014M +1000, and a fitted image thereof is shown in fig. 3 with the abscissa of M/1000 and the ordinate of the clean air test remaining amount (here, a specific ratio).
For example, according to the functional relation, it is assumed that the company or the user specifies the filter element life as the clean air purification amount is attenuated to 50%, that is, the target clean air remaining amount is 50%, where M is 35714. For another example, suppose that the filter life is specified by the enterprise or the user to be 60% of the clean air purification amount, and then M is 28571.
It should be noted that the functional relation between the remaining amount of clean air and the accumulated purge amount is not limited to this, and the functional relation may be a linear functional relation with a high dimension, besides a linear functional relation with a first degree, and the embodiment is not limited to this.
In some optional embodiments, before obtaining a plurality of test accumulated purification amounts corresponding to a plurality of test residual amounts of clean air of the filter element respectively, the method further includes:
and placing the air purification device at the highest operation gear. That is, in the present embodiment, a functional relation between the accumulated purification amount and the remaining amount of clean air is established by testing when the air purification apparatus is in the highest operation gear, and then, when the air purification apparatus is in any one of the operation gears, calculation can be performed by using the functional relation.
In some optional embodiments, the obtaining the real-time accumulated purification amount of the filter element comprises:
predetermining the initial clean air surplus of the air purification device under each corresponding operation gear;
identifying a current operation gear of the air purification device in a current time period, and determining the residual quantity of the current initial clean air based on the current operation gear;
monitoring the real-time pollutant concentration of the current time period, and dividing the current time period into a plurality of micro time periods;
and calculating the sub-accumulated purification amount of each micro time period according to the current initial clean air residual amount, the real-time pollutant concentration and the micro time period.
More specifically, the real-time residual amount of clean air may be calculated according to the real-time accumulated purification amount of the previous micro-period and the functional relation, and the sub-accumulated purification amount of the current micro-period may be calculated according to the real-time residual amount of clean air and the real-time pollutant concentration.
And summing the sub-accumulated purification amounts, and calculating to obtain the real-time accumulated purification amount of the current time period.
If the amount of Clean Air (CADR) is constant during a period of time, and the user or the enterprise monitors the amount of the pollutants in real time, the pollutants may be particulate pollutants, such as PM2.5, for example, or the pollutants may be gaseous pollutants, such as formaldehyde, for example, but of course, the pollutants may be other types of pollutants depending on the type of sensor actually installed in the air purification apparatus. M1 ═ CADR × PM × t in a certain mini-period, the sum of each mini-period t may be periodically made, and the M1 value in this period may be obtained. However, the inventor of the present invention has found that, in actual use, the CADR changes with the change of the gear position and the CADR in the same gear position attenuates with the use of the device, and therefore, the inventor has originally proposed that the real-time CADR residual amount needs to be obtained, and the real-time CADR residual amount can be obtained by a functional relation, and specifically, the related description can be referred to.
According to the method for calculating the service life of the filter element, the CADR implementation residual quantity is calculated, the real-time accumulated purification quantity of the filter element can be more accurately determined, and therefore the calculation accuracy of the service life of the filter element can be improved.
In some alternative embodiments, the final life of the filter element is calculated using the following relationship:
η＝η1*d1+η2*d2；
η1＝M1/M*100％；
