The present invention relates to a cleaning device for an electric dust collector, and more particularly, to a cleaning device for a baffle-type electric dust collector for removing dust particles attached to the dust collecting plate and the discharge electrode by moving up and down along the baffle.

In general, an electrostatic precipitator is a device configured to remove dust particles suspended in air by charging dust particles suspended in gas or air and then separating the charged dust particles from the gas or air by electrostatic force. to be.

The electrostatic precipitator is composed of a discharge electrode and a dust collecting plate, and as the dust collector is used, a large amount of dust particles are attached to the dust collecting plate and the discharge electrode, thereby reducing the charge amount of the dust particles. As a result, the dust collecting efficiency of the dust particles due to the electrostatic force is lowered.

Therefore, in order to improve the dust collecting efficiency of the electric dust collector, it is necessary to periodically remove the dust particles attached to the dust collecting plate and the discharge electrode, and various methods for this have been proposed.

As a conventional apparatus for removing foreign matter adhered to the dust collecting plate and the discharge electrode, Japanese Utility Models Nos. 193-56250 and 193-56251, "the dust collecting plate and the discharge line cleaner" of the electric dust collector, have slots according to the cross-sectional shape of the dust collecting plate and the discharge electrode. The dust is scraped and removed by hanging the hoist and lifting it from the top of the electrostatic precipitator.

However, since these are all methods to scrape off the dust particles, the removal efficiency of the dust particles is high, but not only the scraping plate does not rise and fall smoothly, but also when the scraping plate is tilted or the clearance is kept small for dust removal. There was a problem that the jam occurred and damaged the discharge line or the dust collecting plate.

In addition, Japanese Patent No. 194-102300, "Cleaning device and cleaning method of an electrostatic precipitator," proposes an electrostatic precipitator cleaning device comprising a bogie between the dust collecting plates, a spray nozzle capable of spraying the combusting material, and a rocking device. . However, this spraying method has a low dust removal efficiency because of a blind spot of cleaning.

In addition, Japanese Patent No. 2001-087676, "Washing method and cleaning apparatus for a dry electrostatic precipitator", simultaneously sprays a cleaning fluid at a high pressure to a spray nozzle at a side surface of a dust collector electrode arranged in parallel, at the same time, shakes the spray nozzle, and shakes the dust collector electrode. It provides a method for cleaning the surface of the dust collecting electrode while performing a reciprocating movement in the arrangement direction of. However, this wet cleaning method has a disadvantage of severe corrosion of the equipment due to moisture.

In addition, Korean Patent Publication No. 2002-353110, "vertical thruster for electrostatic precipitator" is a method of continuously removing dust accumulated on the discharge electrode with a vertical axis, a circular disk, a pin, a cam and a hammer for hammering, and Korea Utility Model Publication 2003-317841 "Automatic regenerative electrostatic precipitator" is provided with a scraper or a rotary brush that adheres the surface between the dust collecting electrode and the collecting counter electrode, and moves it in the vertical or horizontal direction of the dust collecting electrode to adhere to the dust. The present invention provides an automatic regeneration device that scrapes and removes dust by physical force, and scattering dust is collected by a vacuum inhaler.

In addition, the "dust collection plate dust removal device of the electrostatic precipitator" of the Republic of Korea Patent Publication No. 2003-53717 is installed a pair of sliding bed, a motor, a screw shaft, a moving table and a guide post on both bottom surfaces of the dust collector, and accordingly the brush roll It is a device to remove dust by moving up and down between the dust collecting plate while rotating automatically.

In addition, Korean Patent Publication No. 2004-12139, "Hammer for hitting the dust collector plate of the electrostatic precipitator" strikes the wrapping bar attached to the dust collector plate with a hammer connected to the motor shaft to separate the dust attached to the dust collector plate.

However, the above-mentioned techniques are mostly inapplicable due to a problem that mechanical damage is inevitable when physically priced to remove dust, and that damage occurs due to high voltage and dust while the mechanical and electrical devices installed inside the dust collector are in operation.

The present invention has been invented to solve the above problems, an object of the present invention is to autonomously run up and down along the baffle of the dust collecting plate, by using a brush to automatically clean the foreign matter attached to the dust collecting plate and the discharge electrode at the same time as dust It is to provide a cleaning device of the baffle-type electric dust collector which can prevent the deterioration of dust collection efficiency.

In order to achieve the object as described above, the cleaning device of the electric dust collector including a dust collector plate and the discharge electrode is formed baffle according to an embodiment of the present invention comprises a brush roll for removing foreign matter attached to the dust collector and discharge electrode; And a foreign material removal unit installed at one end of the brush roll, the rotary motor rotating the brush roll. And an elevating unit configured to elevate the foreign matter removing unit up and down of the dust collecting plate and the discharge electrode.

The elevating unit rotates while being in contact with the front surface of the baffle, the driving wheel is installed on the center left and right; And a base member rotating in contact with the left and right rear surfaces of the baffle, the base member including an idle roll disposed on upper and lower portions of the baffle. A first rotating shaft for rotating the driving wheel; And a lifting motor installed at one end of the base member to rotate the rotating shaft.

The cleaning device of the baffle-type electric dust collector may automatically clean the foreign matter attached to the dust collecting plate and the discharge electrode at the same time to prevent dust collection efficiency from being lowered due to dust.

At this time, the dust particles contained in the air introduced between the dust collecting plates 102 are charged by the negative voltage applied to the discharge electrode 104 to bear a negative electrode. Subsequently, the charged dust particles are separated from the air by being attached to the dust collecting plate 102 having the positive electrode by the electrostatic force.

At this time, the discharge electrode 104 may be formed in a variety of shapes, in particular may be configured to include a plurality of discharge projections (104a) to improve the charging efficiency of the dust particles.

In addition, a baffle (102a) is formed in the dust collecting plate (102) to guide the air flowing in between the dust collecting plates (102) to the discharge electrode (104) and impart oscillation at the same time, thereby promoting dust collection by the dust collecting plate (102). Be sure to
