Abstract

The invention belongs to the technical field of gas disinfection and purification and relates to a wind wheel electrode discharging device. The device comprises a wind wheel electrode, fixed electrodes and a motor, wherein the fixed electrodes are arranged at edges of inner and outer sides of an annular wind wheel; an insulating medium sleeve shell covers the strip-shaped fixed electrodes; fiber cloth covers the blades of the wind wheel electrode; the wind wheel electrode is driven by the motor. The wind wheel electrode discharging device is characterized in that the wind wheel electrode which is conductive in a discharging process is driven by the motor to rotate; an air flow flows through a discharging interface between the fixed electrodes and the wind wheel electrode; pollutants are directly decomposed by plasmas generated by discharging or are adsorbed on fibers covering the blades and then are decomposed by the plasmas. According to the wind wheel electrode discharging device, the problems of discharging nonuniformity and micro-discharging are solved by adopting a rotary electrode, the service life of the electrode is effectively prolonged and the ozone generation rate is reduced; the adsorption fibers coated by nano crystal TiO2 cover the wind wheel blades, so that the adsorption and photocatalysis effects are enhanced, and the air resistance is also reduced; the gas disinfection and purification efficiency is higher, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of gas disinfection and purification, in particular to a wind wheel electrode discharge device. technical background [0002] According to the lifestyle of contemporary people, about 60% of people's life is spent indoors, and urban residents are as high as 80% to 90%. Unless purification measures are implemented, the air quality in public places such as large-scale offices, entertainment, shopping, conferences, and teaching will be severely reduced, which will not only spread diseases, but also make people in a sub-healthy state. Air purification under household conditions is also very important. At present, the outdoor air quality in cities is low. Due to the influence of decoration, furniture, and household chemical products, the indoor air quality is even worse. The content of oxygen, especially negative oxygen ions, is very low, and the concentration of some harmful gases indoors is much higher than out...
