no. 1 example

[0024] see figure 1 , the high-efficiency electrostatic photocatalytic air purification device includes a long cylindrical support 1, a purification channel 11 is formed on its central part, and a plurality of slots 12 are radially provided on the inner wall surface of the support 1 corresponding to the purification channel 11, Conductive plates 2 and photocatalyst plates 3 are plugged into the slots 12 at intervals. The conductive plate 2 and the photocatalyst plate 3 will not block the purification channel 11, the wind pressure loss is small, the noise level can be greatly reduced, and the resonance phenomenon is effectively eliminated. The structure is more compact and the overall volume is smaller. The conductive plate 2 and the photocatalyst plate 3 are easy to disassemble and easy to maintain in the future.

[0025] It also includes a strip-shaped discharge electrode 4 arranged on the geometric center of the purification channel 11, the distance between the discharge el...

no. 2 example

[0035] see figure 2 The main difference between this high-efficiency electrostatic photocatalytic air purification device and the first embodiment is that the cross-section of the discharge electrode 4 in this embodiment is elliptical. The cross section of the slot 12 is shell-shaped, which can effectively increase the surface area of ​​the conductive plate 2 and the photocatalyst plate 3 and improve the air purification effect.

[0036] Other unmentioned parts are the same as the first embodiment and will not be repeated.

no. 3 example

[0038] see image 3 , the main difference between this high-efficiency electrostatic photocatalytic air purification device and the first embodiment is that the cross-section of the purification channel 11 is quincunx-shaped, and the cross-section of the slot 12 is half-moon-shaped. In this embodiment, three conductive plates are used 2. Therefore, the cross-section of the discharge electrode 4 is in the shape of three spikes, and each spike end is aligned with the conductive plate 2, which can effectively increase the surface area of ​​the conductive plate 2 and the photocatalyst plate 3 while ensuring that the discharge electrode 4 is connected to each conductive plate. A uniform electrostatic electric field is formed between the plates 2 to improve the air purification effect.

[0039] Other unmentioned parts are the same as the first embodiment and will not be repeated.

Abstract

The invention discloses an efficient electrostatic type photocatalysis air purifying device which comprises a long-cylinder-shaped support. A purifying channel is formed at the center portion of the long-cylinder-shaped support. A plurality of inserting grooves are formed in the positions, corresponding to the purifying channel, on the inner wall face of the support in a radial shape. Electric conduction boards and photocatalyst boards are alternately inserted and connected into the inserting grooves. The efficient electrostatic type photocatalysis air purifying device is very compact in structure, smaller in overall size, high in dust collecting efficiency and good in harmful gas decomposing effect; and air pressure losses of the purifying channel are low, the noise is low, the resonance phenomenon can be eradicated, and the efficient electrostatic type photocatalysis air purifying device is more stable and more reliable.

Description

technical field [0001] The invention relates to a high-efficiency electrostatic photocatalytic air purification device. Background technique [0002] The high-efficiency electrostatic photocatalytic air purification device is characterized by high dust collection efficiency, the dust collection efficiency is as high as 80%, and it can also capture tiny particles (0.01μm ~ 0.10μm) without replacing the filter material. It has been widely used in various fields of air On the purifier, the conventional electrostatic air purification device usually also has a photocatalyst plate, so that it can not only collect dust, but also decompose harmful gases, such as formaldehyde and benzene. [0003] However, in the prior art, the photocatalytic plate is directly inserted into the cylindrical purification channel, which directly leads to a significant reduction in the wind pressure of the purification channel, causing problems of high noise and serious resonance. Therefore, further imp...
