Description

Integrated Dust Collector

The present invention relates to an integrated dust collector, and more particularly, to an integrated dust collector in which an electrostatic dust collector and a mixed dust collector used by mixing a filter and an electrostatic method are integrally formed.

Recently, due to the increasing interest in air pollution and stricter emission dust regulations around the world, such as China's fine dust problem, measures are urgently needed.

In particular, pulverized coal-fired power plants inevitably emit large amounts of fly ash since coal is made into fine powder and burned in a suspended state.

Fly ash released should be recovered through the dust collector.

Dust collectors are mostly divided into electrostatic dust collectors using discharge electrodes and dust collectors, and mechanical dust collectors filtered using a filter.

The electrostatic precipitator utilizes the corona discharge principle to apply fly ash to the fly ash by applying a high voltage of DC to electrically separate and collect fly ash so that the dust collection efficiency is high and mechanical dust cannot be collected. It has the advantage of being able to collect dust.

However, the electrostatic precipitator has a problem in that it is not possible to quickly collect fly ash emitted in large quantities from the aforementioned thermal power plant because the dust collection efficiency is greatly reduced as the fly ash flow rate is faster.

On the other hand, the mechanical dust collector using the filter has the advantage that the dust collection efficiency does not significantly decrease even if the fly ash (Fly Ash) flow rate is fast.

However, the mechanical dust collector has a problem that the dust collection efficiency is lowered because the filter is clogged gradually during long time filtration.

In order to overcome the above problem, Korean Patent No. 10-0453930 proposes a combination dust collector combining a capacitive dust collector and a mechanical dust collector.

However, the Korean Patent No. 10-0453930 has a problem that the operating cost is excessively required because a large pressure ratio is required during driving because the filter is formed in a honeycomb form.

In addition, the dust collecting pole of the Korean Patent No. 10-0453930 is inclined consistently to have a structure in which fly ash is diffused from the inlet toward the outlet, making it difficult to quickly collect dust due to pressure loss.

On the other hand, the dust collecting pole of Korea Patent No. 10-0453930 has a fatal defect that can not be fixed firmly when fixed to the lower surface of the partition plate because the cross-sectional shape is formed in a straight shape.

Accordingly, the present invention has been made to overcome the problems of the prior art as described above, the object of the present invention is to provide an integrated dust collector that can be quickly collected while maximizing dust collection performance and can be guaranteed durability.

The present invention for solving the above problems and the injection hole is formed on one side and the discharge port is formed on the other side; A boundary plate having a plurality of installation portions formed at regular intervals and partitioning the inside of the main body up and down; A pair of first dust collecting poles spaced apart from each other by being fixed to a lower surface of the boundary plate; A first discharge electrode fixed to a fixed portion formed inside the main body and formed to the outside of the first dust collecting electrode; And a filter formed between the pair of first dust collecting poles while being fixed to the installation unit, wherein the first dust collecting poles are formed at least one, and the filter includes an integrated dust collector, wherein the filter is a hollow filter. .

Preferably, the filter is composed of a first filter and a second filter adjacent to the first filter, wherein the first dust collecting pole has a first partial dust collecting pole inclined downward in a right side from one side of the first filter; A second partial dust collecting electrode having an inclined cross section at the upper right side from the other side of the first filter; An integral dust collector including a third partial dust collecting electrode having an inclined cross section at an upper right side at one side of the second filter and a fourth partial dust collecting electrode having an inclined cross section at a lower right side at the other side of the second filter; It includes.

Preferably, the first dust collector includes an integrated dust collector, characterized in that it has a bent portion.

Preferably, it comprises an integrated dust collector, characterized in that it comprises a; inclination control unit is connected to the first dust collector to adjust the inclination of the first dust collector.

Preferably, the main body includes an integrated dust collector, characterized in that the striking portion for applying an impact force to the first dust collector and the first discharge electrode is formed.

Preferably, the hitting unit includes an integrated dust collector, characterized in that it comprises a timer.

Preferably, the inlet is formed on one side and the outlet is formed on the other side; A first dust collector formed adjacent to the outlet in the case; And a second dust collector formed between the first dust collector and the inlet port, wherein the first dust collector is provided with a pair of first dust collectors spaced at regular intervals and a first dust collector formed outside of the first dust collectors. An integrated dust collector having a discharge electrode and a dust collector having a filter formed between the pair of first dust collectors, wherein the second dust collector is an electrostatic dust collector having a second discharge electrode and a second dust collector installed inside the main body. It includes.

The present invention as described above has the following effects.

First, since the filter is made of a hollow hollow filter, a large pressure ratio is not required, and thus the operating cost is reduced and the dust collection is quick and efficient.

Second, since the first dust collector has a first partial dust collector which is adjacent to the inlet but has a first partial dust collector inclined downward in the right direction and a second partial dust collector inclined in the upper right direction in the cross section, the dust particles entering the inlet can be quickly removed. By inducing it to have an advantage that more effective dust collection is possible without pressure loss.

Third, since the cross section of the first dust collecting pole is formed to be bent, the dust collecting pole is firmly fixed when the dust collecting pole is fixed to the boundary plate, thereby improving durability and increasing the dust collecting area of the dust particles.

Fourth, since the inclination control unit is connected to the first dust collector, there is an advantage of minimizing pressure loss by rotating the first dust collector.

Fifth, since the dust collector is provided with a hitting portion for applying an impact force, there is an advantage of easily removing dust accumulated in the filter or dust collecting pole.

Sixth, since the hitting part has a timer, it is possible to perform dust removal at regular time intervals.

Seventh, by placing a first electrostatic precipitator on the inlet side and a second composite precipitator in which the electrostatic and filter are mixed between the first precipitator and the outlet, the concentration of particulate matter flowing into the filter is greatly reduced. There is an advantage that can minimize the load of the filter cloth.

Eighth, between the inlet and the outlet, the first dust collector, which is an electrostatic dust collector, and the second dust collector, which is a combination of the electrostatic and filter method, are arranged in a horizontal direction, so that a large amount of suspended discharge dust generated instantaneously during dust collection is filtered. Because it collects at, it can maintain more stable dust collection efficiency.

The first dust collecting electrode has a bent portion 215, and the bent portion 215 has a lightning cross section while being bent once as shown in FIG.

Since the bent portion 215 is formed in the cross section of the first dust collecting electrode, the area in contact with the boundary plate 203 is increased, and thus the first dust collecting pole is more firmly fixed to the boundary plate 203.

Since the bent portion 215 increases the surface area of the first dust collector, the dust collecting capability is improved, while when the dust particles come into contact with the first dust collector, the bent portion 215 collides with the bent portion 215 to be finely pulverized to increase dust collection efficiency.

In other words, two first dust collectors 200 and two second dust collectors 300 may be formed.

Meanwhile, as another embodiment of the present invention, three second dust collectors 300 may be formed in plural in a row, and a second dust collector 300 may be formed between the second dust collector 300 and the outlet 120 which are closest to the outlet 120. It will also be preferable that the single dust collector 200 is disposed.

2. 동작원리의 설명2. Explanation of Principle of Operation

<제1실시예에 따른 동작><Operation According to the First Embodiment>

Next, an operation principle according to the first preferred embodiment of the present invention will be described.

The dust gas injected through the injection hole 201 is introduced into the lower space 273 of the first dust collector 200 while being wide and evenly distributed through the expansion pipe 208.

The dust gas introduced into the lower space 273 is guided to the first dust collecting pole 210 along the guide part 217.

At this time, the large and heavy dust particles enter the first partial dust collector 211 and the second partial dust collector 212 adjacent to the injection hole 201, and the small and light dust particles are adjacent to the discharge hole 202. As the third partial dust collecting electrode 213 and the fourth partial dust collecting electrode 214 are entered, the dust collecting process is performed.

At this time, since the first and second partial

dust collecting electrodes

211 and 212 guide the large and heavy dust particles to the first filter 241, an effective dust removing operation can be performed without pressure loss.

On the other hand, the small and light fine dust particles are sufficiently charged while being guided in a direction away from the second filter 242 while being guided by the third partial collecting electrode 213 and the fourth partial collecting electrode 214.

The charged fine dust particles are subjected to dust removal with sufficient time while being moved to the second filter 242 along the third partial collecting electrode 213 and the fourth partial collecting electrode 214.

The dust particles that are subjected to the dust removal process in the first dust collecting electrode 210 are filtered while passing through the filter 240.

The gas from which residual dust has been removed is discharged to the discharge port 202 through the reduction tube 209 while filling the upper space 271.

The dust separated from the dust gas is accumulated down along the inclined surface in the hopper 250 formed under the first dust collector 200 and can be discharged to the outside through the outlet 251 provided at the bottom of the hopper 250.

Meanwhile, as the first dust collector 200 operates, dust is accumulated on the outer circumferential surfaces of the first dust collector 210 and the filter 240.

Dust accumulated in the first dust collecting electrode may be removed by applying an impact force from the striking unit 260 installed inside the main body 100.

Dust accumulated on the outer circumferential surface of the filter 240 may be removed while compressed air is provided through the nozzle 207 provided in the upper space 271.

<제2실시예에 따른 동작><Operation According to Second Embodiment>

Next, the operation principle according to the second preferred embodiment of the present invention will be described.

Since the second embodiment of the present invention differs only in the shape of the first dust collecting electrode 210 in the above-described first embodiment, only the above description will be mentioned.

The dust gas injected through the injection hole 201 enters the lower space 273 of the first dust collector 200 while being widely and evenly distributed through the expansion pipe 208.

The dust gas introduced into the lower space 273 is guided to the first dust collecting pole along the guide part 217.

At this time, as the dust particles collide with the bent portion 215 formed in the first dust collecting electrode, the dust particles are finely crushed to increase dust collection efficiency.

On the other hand, in the bent portion 215 may be a vortex can be formed to maximize the charging effect of the dust particles.

<제3실시예에 따른 동작><Operation According to the Third Embodiment>

After the dust gas is introduced through the inlet 110, it first passes through the second dust collector 310, which is further adjacent to the inlet 110, of the two

second dust collectors

300, 310, and 320.

Since the dedusted gas contains fine dust, the dedusting gas flows back into another second dust collector 320 formed on the right side of the second dust collector 310 to perform another dust removal treatment.

The second dust collector 300 is formed of an electrostatic dust collector including a second discharge electrode (not shown) and a second dust collector (not shown).

The second dust collector 300 and the first dust collector 200 formed in the case are arranged in a row in the transverse direction between the inlet 110 and the outlet 120 in a pair of two each as shown in FIG.

Meanwhile, the dust gas introduced through the inlet 110 passes through a pair of electrostatic type

second dust collectors

310 and 320 in order to be subjected to the first dust removal process and then passes through the pair of first dust collectors 200. It is neatly damped.

The dust gas, which has been subjected to the dust collection process while passing through the second dust collector 320, is injected into the first dust collector 200 adjacent to the second dust collector 320 and is subjected to dust removal, and finally exits the outlet 120 of the case.

In other words, since the discharge port of the first dust collector 200 is in communication with the outlet 120 of the case, the dust-cleaned clean gas is discharged through the outlet 120.
