Description

Technical Field

[0001] The present invention relates to the technical field of air disinfection and purification, in particular to a high-efficiency air disinfection and purification processing device. Background Art

[0002] Air disinfectors disinfect the air through filtration, purification, and sterilization. Besides killing bacteria, viruses, mold, spores, and other such disinfectants, some models can also remove organic pollutants like formaldehyde and phenol from indoor air. They can also kill or filter allergens like pollen. They can also effectively remove smoke and odors from smoking, unpleasant bathroom odors, and human body odor. They offer reliable disinfection and can operate even when people are present, enabling human-machine coexistence.

[0003] The plasma sterilization device is a key component of a plasma air disinfector. The plasma's sterilization efficiency directly impacts its effectiveness. An air disinfector consists of a primary filter, a plasma sterilization device, a UV lamp, and a fan. The primary filter removes large pollutants like flying catkins and hair. The plasma sterilization device uses electric discharge to trap fine particles on a plasma dust collector. The high-frequency electromagnetic field of the plasma destroys the structure of bacteria or viruses, achieving a sterilizing effect. The indoor air is then circulated, achieving a sterilizing, purifying, and disinfecting effect. Common plasma generators on the market today have one electrode made of a metal wire or metal tip and the other made of a thin metal sheet.

[0004] Due to structural reasons, such as positive and negative voltage insulation, plasma generators are large in size and have uneven distribution of positive and negative electrodes. This prevents the plasma device from evenly covering the entire air duct. As a result, some air is not processed as it passes through the duct. After a period of use, the positive electrode dust collector's adhesion efficiency decreases significantly as particulate matter accumulates. Many particles are captured, but due to a lack of adhesion, they cannot be adsorbed, resulting in reduced sterilization efficiency. Negative ion generators adsorb a wider range of particles, so the dust collection rate is relatively fast, requiring timely cleaning. This also affects the sterilization and purification efficiency, resulting in a very high cleaning frequency. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-efficiency air disinfection and purification device to improve the sterilization efficiency, uniform electric field distribution, and enhance the purification effect.

The electrode plasma filter 4 is composed of an insulating honeycomb panel 42, two photocatalytic metal honeycomb panels 41 and a second insulating frame 43. The insulating honeycomb panel 42 and the two photocatalytic metal honeycomb panels 41 are both installed in the second insulating frame 43. The two photocatalytic metal honeycomb panels 41 are placed on both sides of the insulating honeycomb panel 42, and the two photocatalytic metal honeycomb panels 41 are electrically connected to each other. One negative electrode and the other positive electrode of an adjustable dual high-voltage power supply 1 are connected; an electrode primary filter 2, a high-efficiency filter 3, and an electrode plasma filter 4 are sequentially arranged along the direction of air flow; the disinfection and purification treatment device can be used in equipment such as a disinfection machine, an air conditioning box, or an air duct. The adjustable dual high-voltage power supply 1 is fixed to the equipment and can be electrically connected to an external power supply by bolting. The adjustable dual high-voltage power supply 1 has an adjustment range of 5-15 kV. The electrode primary filter 2, the high-efficiency filter 3, and the electrode plasma filter 4 can be sequentially fixed in the equipment by screws, so that air flows through the electrode primary filter 2, the high-efficiency filter 3, and the electrode plasma filter 4 in sequence. A UVC ultraviolet lamp 5 and a negative ion generator 6 are also provided on one side of the electrode plasma filter 4. The electrode plasma filter 4, the UVC ultraviolet lamp 5, and the negative ion generator 6 are sequentially arranged along the direction of air flow. The UVC ultraviolet lamp 5 and the negative ion generator 6 are installed in the equipment, with the UVC ultraviolet lamp 5 close to the electrode plasma filter 4. The negative ion generator 6 can be installed at the exhaust port of the equipment.

[0028] Each high-conductivity metal wire 23 is embedded in the metal frame 24 , and each high-conductivity metal wire 23 on both sides is connected by wires and electrically connected to the positive electrode of the adjustable dual high-voltage power supply 1 , so that a low-voltage electric field is formed between it and the electrode plasma filter 4 .

[0029] The high-efficiency filter 3 consists of a first insulating frame 32 and a HEPA high-efficiency filter layer 31. The HEPA high-efficiency filter layer 31 is arranged in the first insulating frame 32. By adding the HEPA high-efficiency filter layer 31 between the two electrodes, the service life of the device is greatly increased and the working effect is improved.

[0030] The HEPA high-efficiency filter layer 31 can be selected with a filtration grade of H10-H13, so that the disinfection and purification treatment device can meet the disinfection needs of both ordinary environments and Class 100 clean areas, and is convenient for adapting to the needs of different places.

[0034] The working principle of the present invention is as follows: the polluted air first passes through the electrode primary filter 2 for primary filtration, and the particulate matter that has not been filtered by the electrode primary filter 2 enters the high-efficiency filter 3 with the air for further filtration, and the small particulate matter that passes through the high-efficiency filter 3 enters the electrode plasma filter 4. Since a low-voltage electric field is formed between the high-conductivity metal wire 23 and the photocatalyst metal honeycomb panel 41 connected to the positive pole of the adjustable dual high-voltage power supply 1 and the negative pole of the adjustable dual high-voltage power supply 1, it is convenient to adsorb dust particles. The two photocatalyst metal honeycomb panels 41 form a high-voltage electric field, and under the joint action of the UVC ultraviolet lamp 5, when the small particulate matter passes through the electrode plasma filter 4, the bacteria or viruses in the small particulate matter are completely destroyed under the action of the high-voltage electric field and the bombardment and irradiation of ultraviolet rays. The bottom is damaged, such as the cell wall and cell nucleus are electrically broken down, and the charge distribution thereon is destroyed, which directly affects the physiological activities and metabolism of bacteria or virus cells, causing the rapid death of bacteria and viruses; a HEPA high-efficiency filter layer 31 is added between the two electrodes, which greatly increases the service life of the device and facilitates improving the purification and sterilization effect. The nano-photocatalyst attached to the electrode plasma filter 4 is irradiated by the UVC ultraviolet lamp 5 to achieve the effect of photohydrogen ion sterilization and purification, thereby enhancing the efficiency of high-efficiency plasma sterilization and the ability to decompose harmful substances in the air; finally, the treated air is discharged through the exhaust port of the negative ion generator 6 and the disinfection machine, air conditioning box or air duct and other equipment, and the generated negative ions are brought into the indoor air, making the air fresher and more comfortable.
