Description

Air electrostatic sterilization filter

technical field

The utility model relates to the technical field of air sterilization and filtration, in particular to an air electrostatic sterilization filter.

Background technique

An existing air electrostatic sterilization device is equipped with a high-voltage electrostatic ozone generator in the box, and is also equipped with an electric fan or exhaust fan, so that the indoor air continuously enters the high-concentration ozone area in the box from the air inlet of the box to kill bacteria in the air. After that, it is discharged into the room from the air outlet. This device has the following disadvantages: (1) a large amount of higher concentration ozone diffuses into the indoor space with the discharged air, and its concentration cannot be controlled, which may cause harm to the indoor crowd because the ozone concentration exceeds the standard; (2) it cannot Filter the air.

Contents of the invention

The technical problems to be solved by the utility model are: (1) the high-concentration ozone zone only exists in some areas inside the device, and the ozone concentration near the outside of the machine is low, which will not cause harm to the human body; Perform filtration purification.

The technical solution provided by the utility model is as follows: an air electrostatic sterilizing filter, including a chassis 2, an air inlet 12 located at the bottom of the chassis 2 and an upper air outlet 3, and an automatic control power supply located on the chassis 2 Box 1, the box 2 is also equipped with a set of filter element 13, the filter element 13 is a double-layer cylindrical structure, composed of folded filter material 9, metal mesh 11, high-voltage discharge electrode 10 and sealing connectors, the outer layer is folded type filter material 9, the inner layer is a cylindrical metal mesh 11, and the center is provided with a high-voltage discharge electrode 10, which is fixed on the filter element 13 through an insulating block 6, and each filter element 13 is fixed on the flower plate 7 through a sealing ring 8, and its high-voltage The discharge electrodes 10 are connected in parallel to the output terminal of the high-voltage static positive electrode in the self-control power supply box 1, and the cylindrical metal mesh 11 is connected in parallel to the high-voltage ground electrode. The filter elements 13 can be placed vertically and parallel to each other, or can be placed horizontally and parallel to each other. The pleated filter material 9 adopts polyester fiber or polypropylene superfine fiber or activated carbon material. An exhaust fan is housed in the air inlet 12 or the air outlet 3 . The shape of the filter element 13 is cylindrical, square or flat.

When the exhaust fan is arranged at the bottom and the air outlet is arranged at the upper part, it is positive pressure operation, and the exhaust fan can also be arranged at the upper part, and the air outlet is arranged at the lower part, which is negative pressure operation. After the air is filtered by the folded filter material 9, the floating dust is blocked on the outer surface of the filter material, and the clean air flows into the metal mesh 11 of the inner cylinder. The inner cylinder is connected with an AC or DC high-voltage electric field. All viruses and bacteria entering the filter element 13 are killed. Ozone has a good bactericidal function, but if the ozone concentration exceeds the standard, it will cause harm to the human body. The machine is equipped with a control device, which corresponds to a certain space. By adjusting the voltage of the electric field, the amount of ozone discharged within a certain range outside the machine is lower than the national allowable range. But the ozone of the filter element in the machine is still maintained at the concentration of sterilization, guaranteeing that the viruses and bacteria entering the filter element 13 are uninterruptedly killed during the running time. The high-voltage discharge electrode of this machine is isolated by insulation, and its shell and all metal structural parts are reliably grounded, so it is very safe to use.

Compared with the prior art, the utility model has the following beneficial effects:

(1) The pleated circular filter cartridge is used for air filtration. Compared with the non-folded filter material of the same volume, its filtering area is 5-6 times larger. The larger the area, the smaller the resistance, and the better the filtering effect. Under the condition of the same filtering area, the volume of the utility model can be reduced several times, the cost is lowered, and the utility model is convenient for popularization and popularization.

(2) Since the inner layer metal mesh of the folded filter element is used as the ground electrode of the ozone generator, the metal fixing rod of the filter element is used as the discharge electrode of the ozone generator, and the inner cylinder space is used as a high-voltage electric field to generate ozone to sterilize the air, Therefore, the structure of the whole machine is simple and reliable; the generated ozone concentration is high, and the disinfection effect is good.

(3) Since the ozone concentration in the machine can be automatically adjusted, during the process of killing viruses and bacteria in the air flowing through the machine, the ozone concentration discharged outside the machine within a certain range will not exceed the standard. It will not cause harm to the human body during use.
