Abstract
Description
Technical Field
[0001] This utility model relates to the field of air purification equipment technology, specifically to an electrostatic dust removal and sterilization component for filters based on a high-voltage electrostatic field. Background Technology
[0002] Currently, in the field of air purification, traditional air purification equipment has certain limitations in dust removal and sterilization. For example, some equipment has low dust removal efficiency and is difficult to effectively remove fine particulate matter; some equipment using electrostatic technology has a better dust removal effect, but it poses ozone pollution problems, which may cause potential harm to human health and the environment; and most equipment is unable to achieve synergistic and efficient treatment of multiple pollutants, and cannot meet the strict requirements of special scenarios such as industrial flue gas treatment and medical environment purification.
[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an electrostatic dust removal and sterilization component for filters based on a high-voltage electrostatic field, in order to achieve a more practical value. Utility Model Content
[0004] The purpose of this invention is to provide an electrostatic dust removal and sterilization component for filters based on a high-voltage electrostatic field, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrostatic dust removal and sterilization component for filters based on a high-voltage electrostatic field, comprising a housing, dust collection plates, and corona plates. A base plate is mounted on the bottom of the housing, and side frames are attached to both sides of the inner wall of the housing. Side openings are provided inside the side frames. Dust collection plates and corona plates are arranged alternately and parallel on the inner sides of two sets of side frames. The surface of the dust collection plates is covered with an insulating dielectric layer, and a metal electrode is embedded in the dielectric layer of the insulating dielectric layer. An air intake fan is provided on one side of the inner side frame, and a rear clamping plate is provided on the other side of the inner side frame. An internal airflow dispersion plate is provided in the middle of the inner side of the rear buckle plate, and extension plates are symmetrically provided at the upper and lower ends of the internal airflow dispersion plate. A catalytic mesh is provided on the inner side of the extension plate, and unidirectional airflow meshes are symmetrically provided on both sides of the internal airflow dispersion plate.
[0006] Furthermore, mounting plates are provided on both sides of the bottom of the box, and the box forms a detachable structure through the mounting plates and the bottom plate.
[0007] Furthermore, a collection slope is provided at the bottom center of the base plate.
[0008] Furthermore, the box body and the two sets of side structures are connected in a package-like manner.
[0009] Furthermore, the dust collection plate and the corona plate are arranged in parallel and staggered, and the corona plate is connected to a high-voltage power supply.
[0010] Furthermore, the catalyst is loaded onto the surface of the catalytic mesh. The catalyst can react with harmful gases such as formaldehyde and benzene compounds using ozone generated by the high-voltage electrostatic dust removal unit, decomposing them into carbon dioxide and water.
[0011] Furthermore, the internal airflow dispersion plate is coordinated with the two sets of unidirectional airflow nets and the box size.
[0012] This invention provides an electrostatic dust removal and sterilization component for filters based on a high-voltage electrostatic field, which has the following beneficial effects: 1. This utility model discloses an electrostatic dust removal and sterilization component that adopts a two-stage design of "high-voltage electrostatic (ESP) + coupled catalysis (CC)". It generates a 60-120kV high-voltage electric field through corona discharge, causing airborne particulate matter (above 0.01 micrometers) and microorganisms (such as bacteria and viruses) to become charged and adsorbed onto the dust collection electrode, achieving a dust removal efficiency of over 99%. Subsequently, the catalytic stage utilizes ozone to react with harmful gases such as formaldehyde and benzene compounds, decomposing them into carbon dioxide and water, while simultaneously reducing the ozone concentration to a safe threshold, thus addressing the ozone pollution problem inherent in traditional electrostatic technologies. It can simultaneously remove PM2.5, TVOC, bacteria, viruses, and acid mist (such as SO3), with treatment efficiencies of over 99%, 85%, and 99.9% respectively, meeting the combined purification needs of industrial flue gas and indoor air. It has a wide range of applications and achieves efficient dust removal, broad-spectrum sterilization, low ozone emissions, and long-life operation through deep coupling of physical and chemical processes. It is suitable for industrial flue gas treatment, central air conditioning systems, and medical environment purification.
[0013] 2. In this utility model, the entire assembly adopts a modular integrated structure. The air intake fan on the front side is used for dust removal and sterilization. The outer box is detachable and can be separated from the side frame. The side opening slot inside the side frame can directly clean the dust collection plate and corona plate inside. When the distance between electrodes of a traditional ESP is very close and the voltage between electrodes is very high, the electrode edges will generate corona under the influence of the electric field. The corona will discharge to nearby dust, affecting the electric field voltage and thus reducing the filter efficiency. The openings on both sides of the electrode plate can effectively reduce the generation of corona discharge and structurally achieve complete isolation between the discharge electrode plate and the dust collection electrode plate. This structure ensures that there will be no leakage between the electrodes due to dust collection contamination and can greatly improve the dust holding capacity of the filter.
