Problems solved by technology

Furthermore, ions are generally produced together with ozone (for example, CN85102037 added a device for eliminating associated ozone), and the negative ions released into the air may also be negatively charged pollution particles (not equivalent to the negative ions detected in fresh air) , so it is not advisable to install ion-generating devices in areas with human activities
This disadvantage makes the scope of use of this type of purification device very limited
Another disadvantage of releasing ions into the indoor space is that after these ions or charged particles enter the air, the nearby surfaces will be the capture bodies of these particles (such as: wall surface), and these surfaces will be damaged due to the accumulation of more particles. get dirty and not easy to clean

no. 1 approach ）

[0039] refer to figure 1 , the system of the present invention includes a charging component (0101), a forced ventilation component (0102), a filter component (0103), and a housing component (0104) that accommodates the above components and has the function of an airflow duct through which the gas can pass. The contaminated gas medium Driven by the forced ventilation component (0102), it first passes through the charging component (0101) in accordance with the direction of the arrow shown in the figure, in which the suspended particle pollutants are fully charged, and then pass through the filter component (0103). Under the action of the electric field, it is captured by the Coulomb force and left in the filter assembly (0103). The purified gas medium passes through filter components such as figure 2 The ground electrode (0201) shown, after its residual charge is neutralized, the treated gas exits the system.

[0040] In the arrangement of the system, the filter assembly (0...

[0067] In the system of the present invention, the fiber material filled in the filter assembly (0103) can also be made of traditional polymer compound materials. Avoid the problem of secondary pollution to the environment caused by high-cost filter elements with low replacement frequency.

[0068] The benefits of such traditional polymer compound materials are that they are readily available in the market, are inexpensive, and can be recycled after proper cleaning.

[0070] In addition, the fibrous material filled in the filter assembly (0103) is not limited to materials made of cellulose or fibrous materials, but also includes finished products made of fibrous materials with a variety of physical shapes that can allow gas to pass through. Paper products made of pulp, products processed from paper products, or other articles produced by using fibers in woven or non-woven forms, or a combination of two or more of the above materials.

[0071] One of the preferred implementation methods uses similar corrugated or honeycomb paperboards and is arranged in parallel with the direction of the electric field. Loose degradable plant fibers are arranged in the middle. In the case of low wind resistance, a large number of fibers polarized by the electric field will be captured by the charged suspended particles nearby. The beneficial effect is that different forms of fiber materials can be set for suspended particles of different particle sizes, whi...

Abstract

Described is a system for capturing and removing suspended particles in and from a gas medium. The system comprises a charged assembly (0101), a forced ventilation assembly (0102), a filtering assembly (0103), and a pipeline (0104) allowing gas to pass through and containing the above assemblies. The system is characterized in that the filtering assembly (0103) comprises at least two electrodes with different electric potential differences and a poor conductor fibrous material arranged between the electrodes.

Description

technical field [0001] The device of the invention belongs to the technical field of purification and filtration, and relates to a purification and filtration system for removing suspended particles in a gas medium (including but not limited to air). Background technique [0002] HEPA is the most common purification treatment method on the market (HEPA is the abbreviation of High Efficiency Particulate Air Filter in English). HEPA adopts a purely mechanical filtration method, so it is different from ion and electronic purification equipment. Due to the technical process, the general HEPA filter is easier to capture large particles such as pollen, bacteria, and dust, but for particles with a particle size of less than 2.5 microns, the smaller the particle size, the more difficult it is to capture. Generally speaking, such equipment has relatively large wind resistance and requires high-power equipment to provide aerodynamic power, so it will consume more power and produce gr...
