The electric dust collector refers to a device that collects dust that has been negatively charged or positively charged by causing the dust collecting electrode to become an anode and the discharge electrode to become a cathode. Generally, a high voltage is applied between the dust collecting electrode and the discharging electrode to generate an unequilibrium electric field by a corona discharge so that the charged dust or gas is collected by the electrostatic force on the dust collecting electrode. Electrostatic precipitators can be applied to large workplaces where dust or gas is generated due to high discharge electrodes, as well as to workplaces where dust or fine particles act. A high voltage of, for example, 30 to 100 kV is required for the dust or particulate matter in the dust collecting device, and may be divided into a DC voltage method or a micro pulse method according to the voltage application method. Such an electrostatic precipitator needs to be cleaned or cleaned at regular intervals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

Referring to FIG. 1A, the rotating nozzle 10 includes at least one rotating member 11 that extends linearly and is arranged to be rotatable; At least one nozzle tip (111) disposed in the rotating member (11); A movable member (12) having a flow space capable of flowing a cleaning solution; And a rotary connector (13) for rotatably connecting each rotary member (11) to the shifting member (12), wherein the rotary member (11) Due to the difference in the injection pressure of the cleaning solution injected into the tip 111, the rotation of the rotary connector 13 is performed.

The rotary nozzle 10 according to the present invention can be applied to any device requiring cleaning or washing without being limited to the cleaning or cleaning of a dust cell module in which a plurality of dust collecting cells are connected to each other. . The dust-collecting cell module may be installed at an industrial site or an underground space where particulate pollutants are generated, and the rotary nozzle 10 may be automatically operated according to preset conditions. One rotary nozzle 10 may be installed in one dust-collecting cell module, but a plurality of rotary nozzles 10 may be installed as needed.

The rotary member 11 may extend in a linear shape and a plurality of nozzle tips 111 may be disposed along the rotary member 11. [ The straight line shape means roughly a straight line shape and not a straight line shape in a strict sense. The reason for the linearity of the rotary member 11 is that the nozzle tips 111 are arranged in a straight line or a straight line-like shape. Such an arrangement of the nozzle tips 111 in the form of a straight line or a straight line has the advantage that the rotation member 11 can be rotated. The rotating member 11 does not necessarily have to be one. The plurality of rotary members 11 may be arranged so as to intersect with each other. A passage for the flow of the cleaning solution may be formed inside the rotary member 11. [

The rotary member 11 can be coupled to the movable member 12 by the rotary connector 13 and the stationary bracket 14. [ The rotary member 11 may be arranged to be rotatable about the rotary connector 13 and the stationary bracket 14 may have the function of fixing the rotary connector 13 to the movable member 12. A middle portion of the rotary member 11 may be rotatably coupled to the rotary connector 13 and the other end of the rotary connector 13 may be engaged with the stationary bracket 14. [ And the fixing bracket 14 can be coupled to the movable member 12. [ At least one nozzle tip 111 may be disposed on both sides of the rotational position of the rotary member 11.

The movable member 12 may have a hollow cylindrical shape and may have a structure capable of flowing a cleaning solution into the interior thereof. And the supply tube T connected to the storage vessel S storing the cleaning solution may be connected to the moving member 12. [ The connection position of the supply tube T is not particularly limited and may be a plurality of supply tubes T as required. The supply tube T may be connected to the storage container S via the control valve unit V. [ The control valve unit (V) may be an automatic opening / closing valve and may include a pressure regulating unit if necessary. Since the rotary member 11 and the movable member 12 all have a linear structure, a pressure difference may be generated based on a point at which the supply tube T is connected to the movable member 12. [ Because of such a pressure difference, the cleaning solution required for the rotary member 11 may not be supplied. In order to solve such a problem, the number of the supply tubes T may be plural or the moving member 12 may have a double tube structure. For example, the moving member 12 may comprise an inner tube and an outer tube, a supply tube T may be connected to the outer tube, and one end of the rotary connector 13 may be connected to the inner tube. Such a structure allows the cleaning solution to be uniformly supplied while allowing a constant pressure to be applied to each rotary member 11 irrespective of the position where the rotary connector 13 is connected to the movable member 12. [ If necessary, the rotary member 13 may be formed in a double tube structure.

The control valve unit V can control the amount or pressure of the cleaning solution supplied from the storage container S to the movable member 12. [ A supply hole (H) is formed in the storage container (S) so that the storage container (S) is connected to an external supply source of the cleaning solution.
