Problems solved by technology

[0005] 3. The service life of low-pressure mercury lamps is short, generally no more than 15,000 hours. In order to reduce investment costs, low-pressure mercury lamps with a service life of less than 6,000 hours are very common
[0006] 4. There are power connectors at both ends of the low-pressure mercury lamp, and it is inconvenient to lead out the power cord
[0007] 5. The power of low-pressure mercury lamps is generally not high, generally less than about 80 W. When purifying air with large air volume, the installed capacity is large and the cost is high; The power can reach 600 W, but the cost is high, and the service life has not been significantly improved
[0008] 6. There is a risk of mercury pollution

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as Figure 1~2 As shown, an air purification device includes a housing 4, an air inlet 1 and an air outlet 7 arranged at both ends of the housing 4, and a perforated air equalizing plate arranged inside the housing 4 near the air inlet 1. 2. The ultraviolet light generating device fixed inside the casing 4 through the fixing brackets 3 and 5 .

[0037] The material 2 of the perforated air equalizing plate is a corrosion-resistant metal plate, and a certain number of small holes are evenly distributed on the plate, the aperture is 1-50 mm, and the gas velocity of the holes reaches 3-7 m / s; the fixing frames 3 and 5 are made of resistant Made of UV light and oxidation resistant organic material.

[0038] Such as Figure 2~3 As shown, the ultraviolet light generator includes several luminous tubes 13 and pulse power supply 10, which are connected ...

Abstract

The invention relates to an air purifying device. The air purifying device comprises a housing, an air inlet and an air outlet which are formed in the two ends of the housing, a perforated air distributing plate which is arranged inside the housing and close to the air inlet, and an ultraviolet-light generating device which is fixed inside the housing through a fixing rack. The air purifying device is compact in structure, convenient to mount, strong in light energy and relatively complete and quick in sterilization and disinfection function.

Description

technical field [0001] The invention relates to the technical field of purification equipment, and specifically discloses an air purification device. Background technique [0002] Ultraviolet light technology is widely used in the field of air purification because of its simplicity and convenience, as well as its sterilization and disinfection effects. However, in the process of using this technology, there are mainly the following problems: [0003] 1. In the field of air purification, the ultraviolet light used is basically produced by low-pressure mercury lamps. The radiated spectral lines mainly include 253.7 nm and 185 nm, and the spectral line selection surface is narrow. In addition, the pollutants that can absorb 253.7 nm light are very limited. Therefore, 253.7 nm light is more used for sterilization and disinfection, and it is difficult to directly decompose pollutants; 185 nm light can be absorbed by most pollutants, and the photon energy can be It reaches 6....
