Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electrostatic precipitator,

More particularly, the present invention relates to an electric dust collector of a top chute type, and more particularly, it relates to a dust collecting apparatus for preventing dust from being adhered to a discharge electrode by a striking action at an upper portion thereof, And an electric discharge device for discharging the electric discharge.

A dust collecting device refers to a device that separates and collects dust or soot coming from a place such as a power plant through a flue. Generally, the dust collecting device can be divided into a cleaning method, a centrifugal force method and an electric dust collecting method. The cottrell dust collector of the dust collecting apparatus includes a discharge pole (- pole) for discharging the corona, a collecting pole (+ pole) for collecting the charged particles, a DC high voltage power supply and control device, a dust attached to the contaminated discharge pole To the hopper, and a device for transferring and recovering the recovered dust.

In an electric dust collection system, a rapper is charged with a negative charge by a discharge electrode, so that the dust accumulated on the discharge dust collecting plate hardens and adheres to harden the dust collecting efficiency. Therefore, the rapper is used to drop the hardened dust particles into the hopper have. Generally, there are three kinds of contouring devices for applying a shearing force according to the structure of the dust collecting electrode or the dust collecting plate. In the case of the plate dust collecting structure, a hammer / anvil or impact system having a hydraulic or electromagnetic impact unit is applied, tumbling hammers are applied to a rigid structure discharge electrode, and vibrators are applied to a wire electrode .

Generally, an electric dust collector used in a power plant or a large dust collector is installed under an electrostatic precipitator and operated mechanically. In this type of chatter machine, mechanical hammers are connected to the rotating shaft and are used in such a way that the hammer impacts the beam or discharge plate as the rotating shaft rotates. And these chatter systems are designed and used based on two factors: the internal suspension system and the number of surfaces affected by the chatter vibration. Hydraulic chattering devices can generate large impacts, but they must be able to withstand large pressures and have the constraint that dust must be removed without being caught again.

As a prior art related to the dust collecting device, Patent Registration No. 0499449 'bottom-up dry electrostatic precipitator' exists. In the prior art, the flow of the mixed air is designed to be vertical rather than horizontally, so that most of the contaminants sucked are collected at the lower end of the dust collecting pole, and some fine particles not collected are collected at the upper end, And to prolong the life of the insulating material. In the prior art, the chute hammer is installed on the lower side of the inner discharge plate of the dust collector to impact the dust collecting pole, thereby removing the dust from the dust collecting pole and collecting it in the hopper.

Another prior art related to the chattering device is Patent Registration No. 0900799 'Chattering Device for a dust collector of a thermal power plant'. The prior art includes a shaft rotatably installed at a lower portion of each dust collecting plate installed in the dust collecting chamber, a plurality of hammers and arms provided along the longitudinal direction of the shaft and corresponding one to one to the dust collecting plates, The arm is composed of an arm body and an arm cap which can be assembled and disassembled from each other around the shaft, and each arm including the hammer is individually separated from the shaft And the arm body and the arm cap are assembled and disassembled by a screw fastening structure.

Another prior art related to the chattering device is the utility model registration No. 0442045 'Chattering device for electrostatic precipitator'. The prior art includes a driving unit rotated by a motor; A hammer supporting part fixed at a position spaced apart from the driving part; And a hammer supporting part mounted on the hammer supporting part and arranged to look at an electrode for collecting dust and move in contact with the driving part within a predetermined angle range during rotation of the driving part, The present invention relates to a chattering device for a dust collector.

The dust collecting apparatus or the chattering apparatus described in the prior art all relate to an electrostatic precipitator and take a structure that applies a shock to the lower side of the frame or the dust collecting plate using a hammer. As described above, the side chute method in which an impact is applied to the side surface or the bottom of the dust collecting plate has a disadvantage that it is difficult to control the chattering force and the frame is likely to be damaged. In addition, there is a disadvantage in that dust collected and collected on the hammer adheres to the hammer, so that periodic maintenance or cleaning of the hammer device is required, dust adhered to the discharge plate is cured and the desorbed dust can not be efficiently removed. There is a problem that the operator has to go inside the dust collector and clean it. Also, space utilization can be lowered. Further, the prior art does not disclose the arrangement or structure of the dust collecting electrode or the discharge electrode which may affect the dust collecting efficiency.

The dust collecting plate 24 refers to an electrode that can be a dust collecting electrode and accumulates dust or forms a caked dust. It is necessary for the dust collecting plate 24 to have an area and a voltage which are equal to or greater than a certain level to the region where the dust having negative charge is attached by the electric force. Thus, the collecting plate 24 may have a panel or plate shape having an attachment plane 241 and a connecting portion 242. The dust collecting plate 24 may have a structure in which a plurality of units 24a and 24b are connected to each other. Specifically, each of the units 24a and 24b has a mounting plane 241 and a connecting portion 242, and each of the units 24a and 24b is connected to each other by a fastening means 243, Can be formed.

Therefore, the present invention is not limited to the structure of the specific dust-collecting plate 24.

A dust collecting structure according to the present invention having various structures will be described below.

FIG. 3A shows an embodiment of an arrangement structure of dust collecting electrodes that can be applied to the dust collecting apparatus according to the present invention.

3A, the discharge electrode 31 and the dust collecting electrode 32 are arranged alternately in the direction parallel to the direction S of the smoke flow, and are arranged in the direction perpendicular to the direction S of the smoke flow The discharge electrode 31 or the dust collecting electrode 32 may be disposed at intervals.

Each discharge electrode 31 may consist of a charge plane 311 and a discharge frame 312 and each of the collector poles 32 may comprise a dust collection plane 322 and a connector 32. The voltages applied to the respective discharge electrodes 31 or the respective dust collecting electrodes 32 may be the same or different from each other. For example, the discharge electrode 31 disposed at the initial position with respect to the direction of flow of the smoke S may have a voltage of 108 kV, and the discharge electrode 31 disposed at the next position may have a voltage of 120 kV. These different voltages can be applied to the discharge electrode 31 or the dust collecting electrode 32 arranged in a direction perpendicular to the inflow direction S. [

FIG. 3B shows an embodiment of a formation structure of a dust collecting plate which can be applied to an apparatus according to the present invention.

Referring to FIG. 3B, the collecting plate 32 may have a double plate coupling structure, for example, the collecting plate 32 may have a beam-column joint panel structure. More specifically, the dust collecting plate 32 may include an elongated plane 321 and a fastening portion 321a formed at the edge in the direction perpendicular to the extending plane, and the connecting beam 323 is inserted into the fastening portion 321a, Another dust collecting plate 32 may be connected. The fastening portions 321a couple the different plates to each other while simultaneously connecting the dust collecting plates 32 in the vertical direction.

Such a coupling structure has an advantage that the dust-collecting panel can be combined with each other in units of cells, thereby simplifying the manufacturing and construction. At the same time, it has an advantage that the current density distribution of the dust-collecting panel cell is uniform, the anode region can be used effectively and the occurrence of the dead zone is effectively prevented, and the reverse-corona phenomenon is minimized.

The structure of the dust collecting plate 32 can be applied to the charging plane or the dust collecting plane illustrated in FIG. 3A.

Structural features of the dust collecting apparatus according to the present invention will be described below.

3C shows the structural characteristics of the dust collecting apparatus according to the present invention.

3C, in the dust collector according to the present invention, the chattering device 34 is located in the non-dust region NSA where the smoke does not flow and is connected to the dust collecting plate 31 by the fastening device 35 Shock or vibration. The dust collecting plate 31 is located in the dust area SA where the smoke flows and all dust can be attached to the dust collecting plate 31 and then removed by the chattering device 34. [ By allowing the chattering device 34 to be completely separated from the dust area SA, (i) the installation of the chattering device is convenient, (ii) the chattering device can be used for a long time, and (Iii) the life of the chattering device is prolonged, and at the same time, (iv) the control of the chattering force of the chattering device is facilitated.

On the other hand, in general, the dust can be in the form of fine dust that becomes smaller in diameter in the upward direction (U) and dust in a larger diameter in the downward direction (D). In the dust collecting apparatus according to the present invention, since the chattering unit 34 is installed on the upper part, the impact or vibration generally becomes smaller in the downward direction A. The smaller the diameter of the dust, the greater the impact or vibration required for removal. Therefore, the dust collecting apparatus according to the present invention has a structure capable of applying shocks or vibrations consistent with the distribution of the dust diameters to the dust collecting plate 31. Thereby improving the efficiency of dust removal. The dust collecting apparatus according to the present invention can prevent the shock or vibration applied to the entire dust collecting plate 31 by adjusting the spacing distance between the chattering apparatus 34 and the chattering apparatus 34, It is advantageous in that the size can be easily adjusted.

FIG. 4A illustrates structural differences between the dust collecting apparatus according to the present invention and a known dust collecting apparatus.

4A, a structure for applying shock or vibration to the discharge frame 44 in the dust collecting apparatus according to the present invention includes a chattering device 41 on the upper side, a booster device 41 on the lower side of the chattering device 41, And a fastening device 43 for fixing the discharge frame 44 while receiving the voltage by the voltage application device 42 and the voltage application device 42. Therefore, the chattering device 41 is positioned in the non-dust region while the respective devices are vertically combined as a whole.

Referring to FIG. 4 (b), in a known dust collecting apparatus, a rotary shaft 43a is installed at the lower or middle portion of the fixed frame 42a, and a hammer 41a is installed along the rotary shaft 43a. And the dust collecting pole 44a may be provided between the fixed frame 42a. The rotating shaft 43a can be coupled to the fixed frame 42a by a device such as a bracket 45, for example.

In a known dust collecting device, the chattering device is installed in the dust area, and dust can be accumulated in the chattering device. On the other hand, when the chattering device is provided outside the region where the dust collecting electrode 44a is provided, the impact is difficult to be effectively transmitted. When the chattering device is installed between the dust collecting electrodes 44a, it is difficult to maintain or repair the chattering device. As described above, the dust collecting apparatus according to the present invention has a mechanical advantage, a construction or an advantage of maintenance and repair, and a structural advantage over a known dust collecting apparatus.

FIG. 4B illustrates the difference in space utilization between the dust collecting apparatus according to the present invention and a known dust collecting apparatus.

4A, the discharge frame 44 and the dust collecting plate 46 of the dust collecting apparatus according to the present invention may be installed to reach the area adjacent to the housing or the mounting frame 47. 4B, in the known dust collecting apparatus, the chute 41a must be provided outside the discharge electrode 44a and the dust collecting pole 46a, so that the stationary frame 47a is connected to the discharge electrode 44a, Or the dust collecting pole 46a.

If the effective collection distances EL1 and EL2 are the same, it can be seen that the dust collector installation distances L1 and L2 are smaller than the known dust collector. Therefore, the space utilization of the dust collecting apparatus according to the present invention can be relatively increased.

Structural features of the chattering apparatus applied to the dust collecting apparatus according to the present invention will be described below.
