Description

TECHNICAL FIELD [0001] The present invention relates to a particulate collecting apparatus for collecting particulate matter, and a particle collecting system including the particulate collecting apparatus and the particulate collecting apparatus including the particulate collecting apparatus.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a particle collecting apparatus and a particle collecting system including the same, and more particularly, to a particle collecting apparatus and a particle collecting system including the same.

1 is a conceptual diagram showing the basic principle of an electric dust collector according to the prior art.

Referring to FIG. 1, an electric dust collecting device of an induction voltage electrostatic filter included in an electric dust collector ESP will be briefly described. Generally, an electric dust collector includes dust, (Collecting) the dust collecting electrode.

That is, the object to be trapped is attracted toward the dust collecting electrode by a coulomb force (static electricity force) and collected.

An electrostatic filter using such a principle generally generates an electric field by a high voltage applied to a discharge electrode and generates a corona discharge which is a phenomenon in which a portion having a strong electric field is conductive due to a high voltage between two electrodes, Generation and transportation are carried out, and the dust or the like to be collected is charged.

The charged dust or the like is subjected to a force by the Coulomb force generated in the direction of the dust collecting electrode in the electric field, and is attracted to the dust collecting electrode and attached to the surface of the dust collecting electrode.

The electrostatic filter using such an electrostatic dust collecting principle usually has a one-stage type and a two-stage type.

The single-stage electrostatic filter is a collective of the discharge part and the dust collecting part, called the Cottrell dust collector, and is most commonly used as a means of preventing air pollution.

It is widely used as an industrial dust emission preventing device which is operated between 30,000 V and 100,000 V and has a simple structure and excellent dust collecting performance and is currently preventing the discharge of liquid and solid particles generated in various industrial plants.

However, since such a single-stage electrostatic filter repeats charging and collecting dust, it is effective in preventing re-scattering, but there is a problem that reverse rotation phenomenon occurs, a high voltage must be applied to the dust collecting electrode, There is a problem that the dust collecting ability is lost.

In addition, if a dust layer is formed to a thickness of about 8 mm to 12.7 mm by collecting dust on the dust collecting electrode, the dust collecting ability can be maintained only by repeating the collected dust. Therefore, It is necessary to add a chattering device or the like to be added.

If exhaustion is not performed, reverse rotation phenomenon occurs, neutralizing the charged dust, resulting in a significant deterioration of dust collecting performance, and the collected dust is neutralized and re-scattered.

The two-stage electrostatic filter has a discharging part and a dust collecting part separately, and forms an electric field by a voltage difference between a discharging electrode of the discharging part and a collecting electrode of the dust collecting part. When the charged particles are introduced into the electric field through the discharging part, It is attracted to the dust collecting electrode of the dust collecting section and collected.

Such a two-stage dust collector is mainly used for the exhaust treatment with a relatively low concentration of dust because the discharge part and the dust collecting part are separated from the electric field.

Such a two-stage electrostatic filter has an advantage of not causing a reverse current, but it has a problem of discharging re-arid dust as it is, and the structure is relatively complicated.

FIG. 2 is a conceptual diagram showing the basic principle of an electrostatic precipitator using induction voltage according to the prior art.

In order to solve the problems of the above-described one-stage electrostatic filter and two-stage electrostatic filter, an electrostatic precipitator using the induced voltage shown in FIG. 2 has been developed.

The electric dust collecting apparatus shown in FIG. 2 includes an induction voltage plate that grounds the dust collecting electrode and induces an induced voltage induced by a projection-type discharge electrode that exists independently without electrical connection. The electrostatic system is formed to increase the dust collecting ability by adding a driving force to the charged dust attracted to the grounded dust collecting electrode by the Coulomb force.

The electric dust collecting apparatus shown in FIG. 2 is characterized in that a conventional wire-shaped discharge electrode is replaced with a protruding discharge electrode having a saw-like shape to increase the mechanical strength and form a relatively wide charged area.

However, the electric dust collecting apparatuses shown in Figs. 1 and 2 carry out collection at the dust collecting electrode by charging dust, dust or moisture particles contained in the polluted gas to be collected, And the collection efficiency is low for the particles.

Fine particles with a diameter of less than 10 micrometers are a cause of air pollution in recent years and are generally called fine dust particles. The fine dust having a diameter of 10 nanometers to 10 micrometers is referred to as a particulate matter dl. In the case of particulate matter, it is a particle which is very difficult to collect as a dust collector according to the prior art.

Specifically, the suction passage 100 may be configured to suck fine particles 10 suspended in the air to supply the fine particles 10 to the first flow path 200 and the second flow path 300. At this time, a suction fan 110 is mounted in the suction passage 100 to provide a suction force to the suction passage 100, so that the microparticles 10 floating in the air and the atmosphere can be sucked. It is needless to say that the apparatus can be replaced with a suction fan if it is an apparatus capable of providing a suction force to the suction passage 100.

As shown in FIG. 3, the first flow path 200 and the second flow path 300 may be mounted at positions opposite to each other with the separating member 120 interposed in one flow path.

Meanwhile, the first charge unit 210 and the second charge unit 310 may be an ionizer or a corona discharger. The first charging part 210 and the second charging part 310 are particularly limited as long as they are capable of charging the fine particles 10 flowing through the first flow path 200 and the second flow path 300 to a specific polarity.
