A novel air purification system

Abstract

A novel air purification system is disclosed. The system is characterized in that the system includes a plurality of surface dielectric-barrier discharge (SDBD) plasma modules, a nanosecond pulsed power supply, a rotation system, impellers, and the like; the surface dielectric-barrier discharge plasma modules include high-voltage electrodes, dielectric slabs, grounding electrodes and catalyst coatings. According to a technical scheme, the nanosecond pulsed power supply is adopted to stimulate a plurality of the SDBD plasma modules plated with TiO2 photocatalytic films, and a plurality of the SDBD plasma modules are assembled into impeller shapes or blade shapes mounted on the rotation system, and VOCs in high-flux air are efficiently removed through rotating the impellers or blades by a draught fan so as to increase the treatment efficiency or speed for VOCs in air. Beneficial effects of the air purification system are that a novel plasma purification device is simple in structure, modularized and expandable, and problems such as complex devices, small treatment sizes and non-ideal treatment effects in present plasma air purification techniques can be solved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a novel air purification system. Background technique [0002] In recent years, the deterioration of ambient air quality in my country's cities has significantly accelerated, leading to long-term and large-scale smog weather, which seriously affects the quality of life of residents and the ecological environment. PM2.5 (fine particulate matter) has small particle size, large area, strong activity, and is easily accompanied by toxic and harmful substances. It is the primary cause of urban ambient air pollution. Volatile organic compounds (volatile organic compounds, VOCs), mainly including benzene series, organic chlorides, freon series, organic ketones, polycyclic aromatic hydrocarbons (PAHs), etc., are important precursors of PM2.5. It is beneficial to reduce the concentration of PM2.5 in the air. [0003] Industrial waste gas is one of the main sources of VOCs in the...

AI Technical Summary

Problems solved by technology

[0006] In summary, most of the current plasma purification devices and methods go through multiple steps such as ventilation, filtration, adsorption, plasma treatment, and catalytic treatment, and the process is complicated; each process requires corresponding facilities, resulting in a large volume of the device. The cost is high, and parts replacement and maintenance are also troublesome

Moreover, the plasma area is mostly based on corona discharge or dielectric barrier discharge plasma. This method has the disadvantages of small discharge area, small air treatment capacity, ineffective effect, and low energy efficiency, which is difficult to meet the actual application requirements.
