Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.
The filter flushing control method, apparatus, electronic device, and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.
The application realizes that the medium filter automatically executes the functions of positive backwash and automatic pollution discharge according to pollution conditions by optimizing the layout of the electromagnetic valves. Before describing the filter flushing control method of the present application in detail, it is necessary to explain the structural relationship of the filter and each solenoid valve. Fig. 1 is a system schematic diagram of a water treatment apparatus 100 according to an embodiment of the present application.
As shown in fig. 1, the water treatment apparatus 100 includes: a filter 13; and a first electromagnetic valve 3.1, a second electromagnetic valve 3.2, a third electromagnetic valve 3.3, a fourth electromagnetic valve 3.4 and a fifth electromagnetic valve 3.5, wherein an outlet of the first electromagnetic valve 3.1 and an inlet of the second electromagnetic valve 3.2 are respectively connected with an inlet of the filter 13, an outlet of the third electromagnetic valve 3.3, an inlet of the fourth electromagnetic valve 3.4 and an inlet of the fifth electromagnetic valve 3.5 are respectively connected with an outlet of the filter 13, and an outlet of the second electromagnetic valve 3.2 and an outlet of the fifth electromagnetic valve 3.5 are respectively connected with a sewage tank or a mine water tank.
It should be noted that, as a possible implementation manner, the water treatment apparatus 100 is specifically an intrinsically safe water treatment apparatus, and may be another type of water treatment apparatus, which is not limited in this embodiment.
Fig. 2 is a flow chart of a filter flushing control method according to one embodiment of the application.
As shown in fig. 2, the filter flushing control method includes:
step 201, obtaining pressure values of a first pressure sensor and a second pressure sensor at two ends of the filter.
In this embodiment, the filter 13 has a water inlet and a water outlet, where the water inlet and the water outlet are not limited in the direction of entry and exit, and the water inlet may also serve as the water outlet, and similarly, the water outlet may also serve as the water inlet. In this embodiment, the filter 13 may be a media filter, wherein the media refers to a high water-based emulsion used in a downhole fully-mechanized face hydraulic drive system. Of course, the medium is not limited thereto, and may be other substances.
Because of the difference of the raw water quality of mine water of different coal mines, in order to ensure that the water quality of produced water of water treatment equipment is kept relatively consistent at different use places, raw water needs to be filtered through a filter, however, in the use process, the filter can produce pollution phenomenon under the influence of the water quality or the service life. In order to maintain the filter in a normal filtering state, the filter needs to be cleaned and discharged. In the embodiment of the application, the second pressure sensor 11.2 and the third pressure sensor 11.3 are installed at two ends of the filter 13, wherein, taking the direction of raw water flowing of the water treatment equipment 100 as an example, the second pressure sensor 11.2 is close to the front end of the filter 13, and the third pressure sensor 11.3 is close to the rear end of the filter 13. When different sides of the inside of the filter 13 are contaminated, the side of the filter 13 to be cleaned can be judged by the pressure value of the corresponding side pressure sensor. Here, the cleaning effect on different sides of the filter 13 can be achieved by performing the forward cleaning and the reverse cleaning of the filter 13. So-called forward washing, i.e., cleaning the front end to the rear end side of the filter 13; the back washing is to wash the filter 13 from the rear end to the front end.
Here, the pressure values of the second pressure sensor 11.2 and the third pressure sensor 11.3 are uploaded to the electronic control system 24, and the electronic control system 24 is configured to control each solenoid valve according to the pressure values. In the water treatment apparatus 100 of the embodiment of the present application, the signals of all the sensors are communicated to the electronic control system 24, and the electronic control system 24 is communicated to the monitoring center 25 through 485, modbus or other communication protocols. The electronic control system 24 controls the audible and visual alarm system 26 based on the operating conditions of the device. When abnormal conditions such as filter element blockage and the like occur in the water treatment equipment 100, the audible and visual alarm system 26 can realize rapid alarm reminding of problems according to fault diagnosis, so that the defect that the environment noise of the underground working face is large and the inspection period of staff is long is overcome. Here, the monitoring center 25 may be a display control interface, which may display data of each sensor and flowmeter and working states of each electromagnetic valve, and meanwhile, the monitoring center 25 also has a function of parameter setting, and may instruct the electronic control system 24 to implement other required functions.
Step 202, calculating a pressure difference between the second pressure sensor and the first pressure sensor according to the pressure value.
In this embodiment, in order to clearly determine whether the filter 13 needs to be subjected to forward washing, backward washing, or to maintain a normal filtering state, it is necessary to calculate the pressure difference between the third pressure sensor 11.3 and the second pressure sensor 11.2. Here, the body performing the calculation is the electronic control system 24, and when the electronic control system 24 obtains the pressure values of the pressure sensors, the pressure values of the third pressure sensor 11.3 and the second pressure sensor 11.2 are automatically calculated according to a program set in the system.
And 203, comparing the magnitude relation between the pressure difference and a preset pressure threshold value, and outputting a comparison result.
In this embodiment, the preset pressure threshold may be 0, and when the pressure difference is greater than 0, this means that the pressure at the rear end of the filter 13 is greater than the pressure at the front end, so that it may be determined that cleaning is required at the rear end side of the filter 13; when the pressure value is equal to 0, this means that the filter 13 is in a filtering state, so that no cleaning is required; when the pressure difference is smaller than 0, this means that the front end pressure of the filter 13 is larger than the rear end, and it can be determined that the front end side of the filter 13 needs cleaning.
It should be noted that, the method of comparing the pressure difference with the preset pressure threshold value is used to determine whether the filter needs to be cleaned, which is not the only method, and the polluted condition of the front end and the rear end of the filter can be further determined by analyzing the water flow rate flowing through the front end and the rear end of the filter and determining the water flow rate in unit time.
And 204, generating electromagnetic valve combination information according to the comparison result.
In some embodiments, as a possible implementation manner, generating electromagnetic valve combination information according to the comparison result may include: if the pressure difference is larger than the preset pressure threshold, generating the first electromagnetic valve combination information; if the pressure difference is equal to the preset pressure threshold value, generating the second electromagnetic valve combination information; and if the pressure difference is smaller than the preset pressure threshold value, generating the third electromagnetic valve combination information.
Here, the first solenoid valve combination information, the second solenoid valve combination information, and the third solenoid valve combination information correspond to a forward washing state, a filtering state, and a reverse washing state of the filter, respectively.
In this embodiment, the solenoid valve combination information does not refer to selecting a different solenoid valve for combination, but refers to marking the on-off state of the solenoid valve after selecting a different solenoid valve, and the marking is used as a combination. For example, the first solenoid valve 3.1, the second solenoid valve 3.2, the third solenoid valve 3.3, the fourth solenoid valve 3.4, and the fifth solenoid valve 3.5 in the embodiment of the present application are selected, and 1 is defined as on, and 0 is defined as off. The combination of the respective solenoid valves 3.1 to 3.5 may be: 11000. 00111, 11001, 10110, and the like. In this embodiment, the first electromagnetic valve combination information is: 10001; the second electromagnetic valve combination information is as follows: 10010; the third electromagnetic valve combination information is as follows: 01100.
and step 205, controlling the working state of each electromagnetic valve according to the electromagnetic valve combination information.
In some embodiments, as a possible implementation manner, the controlling the working state of each solenoid valve according to the solenoid valve combination information may include: if the electromagnetic valve combination information is the first electromagnetic valve combination information, controlling to open the first electromagnetic valve and the fifth electromagnetic valve, and closing the second electromagnetic valve, the third electromagnetic valve and the fourth electromagnetic valve; if the electromagnetic valve combination information is the second electromagnetic valve combination information, controlling to open the first electromagnetic valve and the fourth electromagnetic valve, and closing the second electromagnetic valve, the third electromagnetic valve and the fifth electromagnetic valve; and if the electromagnetic valve combination information is the third electromagnetic valve combination information, controlling to open the second electromagnetic valve and the third electromagnetic valve, and closing the first electromagnetic valve, the fourth electromagnetic valve and the fifth electromagnetic valve.
In this embodiment, taking the third electromagnetic valve combination information 01100 as an example, after the electronic control system 24 collects the working state information 01100 of the first electromagnetic valve 3.1 to the fifth electromagnetic valve 3.5 through the electromagnetic valve sensor, control instructions can be respectively issued to the first electromagnetic valve 3.1 to the fifth electromagnetic valve 3.5, so that the second electromagnetic valve 3.2 and the third electromagnetic valve 3.3 are opened, and the first electromagnetic valve 3.1, the fourth electromagnetic valve 3.4 and the fifth electromagnetic valve 3.5 are closed. Therefore, the raw water 27 is caused to flow from the rear end to the front end of the filter 13 via the third solenoid valve 3.3, and then flows to the blowdown tank or the mine water tank via the second solenoid valve 3.2, thereby realizing a function of backwashing the filter 13. The functional principles of the other forward washing and filtering are similar and will not be described in detail herein.
According to the filter flushing control method, the pressure values of the first pressure sensor and the second pressure sensor at the two ends of the filter are obtained; calculating the pressure difference between the second pressure sensor and the first pressure sensor according to the pressure value; comparing the magnitude relation between the pressure difference and a preset pressure threshold value, and outputting a comparison result; generating electromagnetic valve combination information according to the comparison result; and controlling the working state of each electromagnetic valve according to the electromagnetic valve combination information. Therefore, the filter can automatically execute the functions of positive backwashing and automatic pollution discharge according to pollution conditions.
