Background
The electrostatic dust removal is one of gas dust removal methods, and the principle is as follows: the dust-containing gas is electrically separated when passing through a high-voltage electrostatic field, and dust particles and negative ions are combined to be charged negatively and then tend to discharge on the surface of the anode to be deposited. That is, in a strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of rushing to the positive electrode, so that the dust particles are negatively charged and adsorbed to the positive electrode to be collected.
The existing electrostatic dust collection-based purifier adopts a conductive plastic filter screen, and after the high-voltage power is switched on, the filter screen starts to purify without replacing the filter screen. The conventional activated carbon adsorption filter screen cannot remove dust when saturated, and the filter screen needs to be replaced regularly.

Referring to fig. 1, the present application provides a method for compensating the working performance of a filter screen, and the main steps of the method are described as follows.
Presetting initial voltage, first time and second time for enabling the filter screen to work;
when the filter screen works normally, judging the working state of the whole machine;
when the whole machine is in a working state and the running time of the whole machine exceeds a first time, the voltage regulation output duty ratio of the initial voltage is increased, the output voltage is obtained and output, and the voltage regulation output duty ratio of the initial voltage is linearly increased along with the increase of the time;
when the whole machine is in a standby state or a shutdown state and the standby time of the whole machine exceeds a second time, the voltage regulation output duty ratio of the initial voltage is reduced, the output voltage is obtained and output, and the voltage regulation output duty ratio of the initial voltage is linearly reduced along with the increase of the time.
In this embodiment, the first time may be 6 hours, and the second time may be 6 hours. The unit of the filter screen performance parameter is cubic per hour.
Laboratory test results show that the performance of the filter screen fluctuates in the operation process of the whole machine, specifically, the performance of the filter screen is higher when the whole machine starts to work, and then the performance of the filter screen gradually decreases and tends to be stable along with the increase of the working time. I.e. the screen will have a certain performance degradation during short run.
The event is according to the performance curve of filter screen work, reachs the required voltage value of filter screen when the complete machine moves to different time points, through predetermined pressure regulating change, when the filter screen contact is good, based on complete machine work, standby, down time, carry out filter screen operating voltage's parameter adjustment for output voltage increases or reduces based on time linearity, with the operating voltage who changes to apply on the filter screen, avoids the filter screen performance in earlier stage to fluctuate, makes the filter screen keep the state of performance preferred all the time when normal work.
Further, presetting a third time and a fourth time which are greater than the first time and the second time;
when the whole machine is in a working state and the continuous operation time reaches a third time, stopping adjusting the voltage-regulating output duty ratio of the initial voltage to obtain and output an output voltage;
and when the whole machine is in a standby state or a shutdown state and the continuous shutdown time reaches the fourth time, stopping regulating the voltage regulation output duty ratio of the initial voltage and recovering the regulated voltage regulation output duty ratio to the initial preset value.
In this embodiment, the third time may be 72 hours, i.e., 3 days, and the fourth time may be 72 hours.
And presetting a third time to avoid the influence on the purification performance of the filter screen and even damage to the filter screen due to excessive adjustment of the initial voltage regulating output duty ratio of the whole machine in a working state.
Presetting a fourth time to recover the initial voltage regulation output duty ratio of the whole machine in a standby state or a shutdown state to an initial preset value, wherein in the embodiment, the initial preset value is zero, namely, the parameter of the regulation output duty ratio is cleared; and when the shutdown or standby state is judged, the power failure detection is actually carried out, so that the high-voltage output voltage of the next complete machine during the next work is set based on the time setting mode in the state, the working voltage of the filter screen is initialized, and the adjustment of the input voltage of the filter screen in the next time is facilitated, wherein the adjustment is more in line with the actual running condition.
Further, the step of judging the working state of the whole machine comprises:
acquiring a voltage value of the whole machine voltage after voltage division by two voltage dividing resistors;
when the voltage value is larger than a first preset value, the whole machine is judged to be in a working state;
and when the voltage value is smaller than a second preset value, judging that the whole machine is in a standby state or a shutdown state.
Because of too high unable direct collection of complete machine voltage, with the help of obtaining the voltage value after complete machine voltage passes through two divider resistance partial pressures, the operating condition of complete machine is judged indirectly, and then can adopt different regulation tactics output variable high voltage electricity to supply power for the filter screen pertinence, and regulation and control is more accurate, and the regulation and control effect is better.
In conclusion, when the filter screen is in good contact, the working voltage of the filter screen is initialized, the working state of the whole machine is judged, and the running time is calculated. When the whole machine is in a working state and the running time of the whole machine reaches the required time, the voltage regulation output duty ratio of the initial voltage is increased, the output supplies power to the filter screen, and the voltage regulation output duty ratio of the initial voltage is linearly increased along with the increase of the time, so that the performance of the filter screen is continuously improved along with the increase of the working time and is kept in an optimal state; when the whole machine is in a standby state or a shutdown state and the standby time of the whole machine reaches the required time, the voltage regulation output duty ratio of the initial voltage is reduced, the output supplies power for the filter screen, and the voltage regulation output duty ratio of the initial voltage is linearly reduced along with the increase of the time, so that the electric energy loss of the whole machine is reduced, and the energy is saved.
