The present invention relates to an apparatus for cleaning a discharge electrode type electric dust collector, and more particularly, a discharge electrode traveling that can easily remove a foreign matter attached to a dust collecting plate for separating dust contained in air and a discharge electrode for generating a discharge using a high voltage direct current power. It is related with the type | mold electric dust collector cleaning apparatus.

In general, an electric precipitator is a high-voltage direct current power source is added between the discharge electrode and the dust collecting plate to form a charge layer and ionizes and removes the dust passing through it.

As shown in FIGS. 1 to 3, the electrostatic precipitator is provided in parallel so that the discharge electrodes 1 provided with the plurality of discharge protrusions 5 in the longitudinal direction in the front and rear directions are swept at predetermined intervals, and the discharge electrodes ( The dust collecting plate 2 is arranged in multiple layers between 1), and the air moving path 4 which air moves is formed between the dust collecting plates 2, and the air collecting plate 2 is moved. Baffles 3 are provided at equal intervals so as to generate vortices.

Accordingly, when power is applied to the discharge electrode 1 when the air is moved through the air movement path 4, discharge occurs at the discharge protrusion 5 of the discharge electrode 1, and thus the discharge electrode 1 and the dust collecting plate 2. The charge layer is formed between the layers, and the dust contained in the air passing through the air movement path 4 is ionized to adhere to the surface of the dust collecting plate 2 and the clean air from which the dust is removed is discharged in the opposite direction.

At this time, the baffle (3) is to cause the vortex in the flow of air to collect the dust near the dust collecting plate 2, so that the dust is easily attached to the dust collecting plate (2).

The dust collector is attached to the dust collecting plate (2) and the discharge electrode (1) to reduce the dust collection efficiency when used for a long time to remove the foreign matter attached to the collecting plate (2) and the discharge electrode (1) to prevent the dust collection efficiency deterioration have.

As a conventional apparatus for removing foreign matter attached to the dust collecting plate 2 and the discharge electrode 1, Japanese Utility Model "Cleaning plate and discharge line cleaner of an electric dust collector" (JP 1993-56250, 56251) is a cross section of the dust collecting plate and the discharge electrode. Scraping is eliminated by making slots according to the shape and hanging hoists up and down from the dust collector.

However, when the clearance is kept small for dust removal, a friction occurs due to friction between each other, which causes difficulty in actually raising and lowering.

In addition, the Japanese patent "Cleaning device and cleaning method of an electrostatic precipitator" (JP 1994-102300) proposes an electrostatic precipitator cleaning device comprising a boil between the dust collecting plates, a spray nozzle and a fluctuation device capable of injecting the combustibles between the dust collecting plates. Doing.

However, this spraying method has a low dust removal efficiency because of a blind spot of cleaning.

In addition, Japanese patent "Washing method and cleaning apparatus for a dry electrostatic precipitator" (JP 2001-087676), while spraying the cleaning fluid at high pressure to the injection nozzle at the side of the dust collector electrode arranged in parallel, while shaking the injection nozzle and collecting dust It provides a method for cleaning the surface of the dust collecting electrode while performing a reciprocating movement in the arrangement direction.

However, this wet cleaning method has a disadvantage of severe corrosion of the equipment due to the actual moisture.

In addition, the domestic patent "vertical thruster for electrostatic precipitators" (2002, 10-0353110) is to continuously remove dust accumulated on the discharge electrode with a vertical axis, a circular disk, a pin, a cam and a hammer for hammering, the domestic utility model "automatic Regenerative Electrostatic Precipitator "(2003, 20-0317841) installs a scraper or a rotary brush that adheres the surface between the dust collection electrode and the collection counter electrode, and moves it in the vertical or horizontal direction of the dust collection electrode and attaches it to the surface. It provides an automatic regenerative device that scrapes off by physical force, and scatters dust collected by a vacuum inhaler.

In addition, the domestic patent "dust collection plate dust removal device of the electrostatic precipitator" (2003-0053717) installs a pair of sliding beds and motors, screw shafts, moving table and guide posts on the bottom surface of the dust collector plate, the brush roll is automatically It is a device that removes dust by moving up and down between the dust collector plate while rotating.

In addition, the domestic patent "hammer for hitting the dust collector plate of the electrostatic precipitator" (2004-0012139) separates the dust attached to the dust collector plate by hitting the wrapping bar attached to the dust collector plate with a hammer connected to the motor rotating shaft.

However, the domestic technologies described above are mostly low in practical application because mechanical damage is inevitable when physically priced to remove dust, and mechanical and electrical devices installed inside the dust collector are damaged due to high voltage and dust during operation. There was a problem.

The present invention has been proposed to solve the above problems, autonomous driving up and down along the discharge electrode and at the same time by using a brush to automatically clean the foreign matter attached to the dust collecting plate and the discharge electrode to prevent the dust collection efficiency decrease due to dust It is an object of the present invention to provide an electrostatic dust collector cleaning apparatus.

Discharge electrode cleaning type electric dust collector cleaning apparatus according to the present invention for achieving the above object is a cleaning device for removing the foreign matter attached to the dust collector plate and the discharge electrode in the electric dust collector, the agent is rotated in contact with the front surface of the discharge electrode 1 and 3 idle rolls are respectively provided at the lower and upper portions thereof, and a plurality of lifting rolls are arranged so as to be sequentially inserted into the base having the second idle roll rotated in contact with the rear surface of the discharge electrode in the center and the discharge protrusion formed on the discharge electrode. Elevating means consisting of a rotating plate provided at equal intervals and a lifting motor installed on a base to rotate the rotating plate; And a brush roll for removing foreign matters attached to the dust collecting plate and the discharge electrode while being lifted by the elevating means, and a foreign matter removing means comprising a rotating motor installed at one end of the brush roll to rotate the brush roll. After the slot is prepared in the base and the slider connected to the support bar moves along the slot and adjusts the distance between the second idler roll and the back of the discharge electrode to install and remove the cleaning device. And mounting means for inserting and securing a pin to the slider.

Hereinafter, the characteristics of the discharge electrode type dust collector cleaning apparatus according to the present invention will be described.
