Description

Electrostatic precipitator that can be cleaned during operation}

The present invention relates to an electrostatic precipitator that can be cleaned during operation. More specifically, the present invention relates to an electrostatic precipitator housing formed with an inlet and an outlet, respectively, by circulating a discharging wire and a dust collection wire that can be circulated in response to the driving of the circulation drive motor. By being configured to be immersed in washing water during operation, the discharge electrode and dust collection electrode can be automatically cleaned without stopping the operation of the electrostatic precipitator, and the configuration for cleaning the discharge electrode and dust collection electrode can be easily cleaned during operation. It is about electrostatic precipitator.

In general, electrostatic precipitators are installed in incinerators, boiler desulfurization facilities, and other fine dust and harmful gas removal facilities and are widely used to prevent air pollution.

These electrostatic precipitators usually apply a high voltage of direct current to the discharge electrode from the high voltage generator, but connect the (-) electrode to the discharge electrode to apply a (-) charge to the dust particles contained in the air passing between the discharge electrode and the dust collection electrode. By doing so, the dust is removed by inducing it to attach to the dust collection electrode, which has a relatively positive polarity. At this time, depending on the method of cleaning the dust attached to the dust collection electrode, it is largely divided into dry type and wet type.

At this time, the dry electrostatic precipitator is a method of cleaning by applying a shock to the dust collection electrode by lapping, thereby dropping the attached dust.

However, dust with strong adhesion or stickiness is not easily removed from the dust collection electrode, which causes the problem of lowering the electrical conductivity of the dust collection electrode and lowering dust collection efficiency.

On the other hand, the wet electrostatic precipitator was developed to compensate for the shortcomings of the dry electrostatic precipitator, and adopts a method of cleaning by supplying water to the surface of the dust collection electrode in an intermittent or continuous manner.

Among these, the method of forming a water film continuously on the dust collection electrode to prevent contamination of the dust collection electrode (dust collection plate) while allowing cleaning is very useful, especially in treating dust with low resistivity or dust with strong adhesiveness and age hardening.

However, since about 100 to 200 of these wet electrostatic precipitators are installed in one treatment unit, serious problems will occur if they are not maintained horizontally.

In other words, when assembling hundreds of dust collectors, precise assembly is virtually difficult, so the level cannot be maintained accurately. In this case, the overflowed water does not form an even water film and forms a water stream in some places, or there are places where the water film does not form. This phenomenon causes sparks to form during discharge or dust attaches to the dust collection electrode, resulting in poor discharge and eventually loss of the function of the dust collector, making it inconvenient to clean it one by one after disassembly. , it leads to the problem of wasting money and time.

In addition, if the level is not accurate, it is difficult to maintain, and not only does it cause the inconvenience of having to flow more water in the direction where the level is higher, but it also causes difficulties in control, resulting in deterioration in the function of the dust collector and shortening its lifespan.

To overcome these problems, a wet electrostatic precipitator has been proposed.

That is, the wet electrostatic precipitator has a cylindrical dust collection electrode installed inside the housing, and a rod-shaped discharge electrode is installed at the center of the dust collection electrode.

Additionally, a cap is attached to the upper side of the dust collection electrode, which discharges the continuously supplied water downward in a spiral fashion to form a water film on the inner surface of the dust collection electrode.

Therefore, when voltage is applied to the discharge electrode through a high voltage supply device, a discharge occurs toward the water film, charging fine particles such as dust, and then moving them toward the dust collection electrode by the electric field, where they are collected and removed in the water film flowing down.

However, since the cap has a rim for fixing it to the dust collection electrode, which protrudes from the entire upper outer peripheral surface, when an excessive amount of water flows in through the overflow hole, the rising water level is blocked by the rim, thereby preventing the water from forming a water film. Supply and discharge become difficult.

In addition, when the wet electrostatic precipitator is large, the discharge electrode must be fixed to the upper and lower supports, but there is a problem in that the water forming a water film falls downward and contacts the discharge electrode and the lower support, causing a spark discharge.

Considering this, a vertical wet electrostatic precipitator has been proposed in patent application number 10-2017-0178135.

Looking at the conventional vertical wet electrostatic precipitator, a water film is formed on the inner surface of the dust collection electrode by water supplied from the upper side, and a discharge electrode is installed at the inner center of the dust collection electrode. A supply water tank is formed on the outside of the upper end, a plurality of inlet holes communicating with the supply water tank are formed radially on the upper outer peripheral surface of the dust collection electrode, and a plurality of inclined discharge grooves are formed radially on the outer peripheral surface of the upper side of the dust collection electrode. The forming member is coupled, and on the outer peripheral surface of the water film forming member, a plurality of vertical protrusions are formed radially at intervals upward from the discharge groove, and a locking protrusion is formed at the upper end of the vertical protrusion for fixing the water film forming member to the dust collection electrode. The space formed between the vertical protrusion and the discharge groove and between the vertical protrusions communicates with each other, and the inlet hole is formed between the vertical protrusion and the discharge groove, and a discharge water tank into which water forming a water film falls below the dust collection electrode. is formed, the discharge water tank is formed with a plurality of drain pipes that discharge water downward, and the discharge water tank is comprised of a drainage separator pipe that is inserted into the lower side of the dust collection electrode and prevents spark discharge of the lower support connected to the discharge electrode. do.

However, in a conventional vertical wet electrostatic precipitator configured as described above, upper and lower injection parts are installed at the inner upper and lower parts to transport water from the water tank through a pump and spray it downward and upward through a plurality of nozzles, respectively. Therefore, not only does the equipment of the electrostatic precipitator require a lot of manufacturing costs due to its large size, but it also has the disadvantage of having to temporarily stop the device when trying to remove dust attached to the dust collection electrode.
