Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electrostatic precipitator used for cleaning air and the like.

[0002]

[Prior Art]

 In a conventional electrostatic precipitator, multiple dust collecting plates and multiple high voltage plates are arranged one after the other in parallel, and a high voltage is applied between the dust collecting plate and the high voltage plate. Then, there is one in which dust in the air is collected on a dust collecting electrode plate (for example, Japanese Utility Model Application No. 62-168746).

[0003]

[Problems to be solved by the device]

 However, in the conventional case, it is difficult to completely clean the electrode plates because the gap between the electrode plates is narrow and brushing between the electrode plates is difficult to enter when cleaning the electrode plates. Therefore, if the space between the electrode plates is widened to facilitate cleaning, the dust collection efficiency will deteriorate and a large applied voltage will be required.

In view of the above problems, the present invention is to make it possible to easily wash the electrode plate without deteriorating the dust collection efficiency.

[0005]

[Means for Solving the Problems]

 The technical means of the present invention for solving this technical problem is that a plurality of dust collecting electrode plates 2 and a plurality of high voltage electrode plates 11 are arranged so as to be arranged in parallel alternately one by one. In the electrostatic precipitator in which high voltage is applied between the high voltage electrode plate 2 and the high voltage electrode plate 11, dust in the air is collected in the dust collecting electrode plate 2. The dust collecting section 3 is formed by connecting the plurality of high voltage electrode plates 11 in parallel with each other at intervals. The high-voltage section 12 is provided separately, and the dust collecting electrode 3 of the dust collecting section 3 and the high-voltage electrode plate 11 of the high-pressure section 12 are alternately arranged with respect to the dust collecting section 3. They are arranged so that they can be inserted and fixed so that they are arranged in parallel.

[0006]

[Action]

 When using an electrostatic precipitator, set the high-voltage section 12 so that the dust-collecting electrode plates 2 of the dust-collecting section 3 and the high-voltage electrode plates 11 of the high-voltage section 12 are alternately arranged in parallel. By inserting and fixing it in 3 and applying a high voltage between the dust collection electrode plate 2 and the high voltage electrode plate 11, the dust particles in the air can be efficiently collected in the dust collection electrode plate 2. be able to.

When the electrode plates 2 and 11 are washed, the high pressure part 12 is removed from the dust collecting part 3 to widen the gap between the electrode plates approximately twice, so that the electrode plates 2 and 11 can be brushed. Can be easily washed.
