Embodiment approach 1

[0031] figure 1 A schematic diagram showing the dust collection equipment of Embodiment 1 of the present invention. In addition, figure 2 Indicates its main part.

[0032] The dust collection device 1 includes: a plurality of dust collection bodies 2; a friction body 3 that rubs the dust collection body 2 to charge static electricity; a frame body composed of an outer frame 5 covering them; and holds the friction body 3 The driving part 4 frictionally moves along the outer surface of the dust collecting body 2.

[0033] The plurality of dust collecting bodies 2 are arranged at intervals with each other so as to form an air passage 20 between adjacent dust collecting bodies 2. That is, the dust collecting body 2 is arranged facing each other across the air duct 20. In addition, the outer shell 5 includes an inflow port 51 through which air flows in and an outflow port 52 through which air that has passed through the air passage 20 flows out. The air containing particles to be tr...

Embodiment approach 2

[0062] In the dust collecting facility of the second embodiment, the structure of the dust collecting body 2 is different from that of the first embodiment, and is the same as the first embodiment except for this. Hereinafter, the description will focus on the differences.

[0063] Figure 7 The main part of the dust collector of Embodiment 2 is shown. The dust collecting device of the second embodiment includes a first dust collecting body 22 and a second dust collecting body 23 as the dust collecting body 2. The first dust collecting body 22 is positively charged by friction with the friction body 3. The second dust collecting body 23 is negatively charged. One of the dust collecting bodies 2 arranged facing each other is the first dust collecting body 22 and the other is the second dust collecting body 23. A polyamide (PA6) with a strong tendency to be positively charged by friction is cited as an example of the positively charged first dust collector 22, and a polypropylene...

Embodiment approach 3

[0074] In the dust collector of the third embodiment, the structure of the friction body 3 is different from that of the first embodiment, and is the same as the first embodiment except for this. Hereinafter, the description will focus on the differences.

[0075] Picture 8 The main part of the dust collection device of Embodiment 3 is shown. In the dust collection device of the third embodiment, the friction body 3 includes a first friction material 33 that is negatively charged by friction with the dust collection body 2 and a second friction material 34 that is positively charged. The first friction material 33 and the second friction material 34 are arranged such that one of the dust collectors 2 facing each other across the air passage 20 is rubbed by the first friction material 33 and the other is rubbed by the friction material 34. In addition, when one dust collecting body 2 is sandwiched by a plurality of friction bodies and rubbed, one dust collecting body 2 is rubbed...

Abstract

A dust collection device (1) is provided with: a plurality of dust collection bodies (2) that are charged by friction and arranged with spaces therebetween such that air ducts (20) for passage of airare formed; and one or more friction bodies (3) for applying friction to and charging the dust collection bodies. At least one of the dust collection bodies facing each other across an air duct has one or more protruding parts (21) protruding into the air duct. With this dust collection device, it is possible to improve particle collection efficiency in a friction charged dust collection device byforming a nonuniform electric field surrounding a charging body so as to induce gradient force.

Description

Technical field [0001] The present invention relates to a dust collection device that collects dust by generating static electricity by friction, and an air conditioner equipped with the dust collection device. Background technique [0002] An electric dust collector is one of dust collection equipment that collects dust in the air. The electric precipitator has a charging part and a dust collecting part. The electrostatic collecting mechanism realizes the collection of dust with low pressure loss. The charging part applies a high voltage to the linear electrode with a high voltage power supply to perform corona discharge. The generated ions charge the dust in the air, and the dust collecting unit forms an electrostatic field by applying a high voltage between the flat electrodes with a high-voltage power supply, and electrostatically collects the charged dust on the flat plate. However, in general, electric dust collecting parts are difficult to operate due to the use of electr...
