Description

Electrostatic precipitator for easy cleaning

The present invention relates to an electrostatic precipitator, specifically, it is difficult to clean the dust collecting part and must be dried after cleaning, so the electrostatic precipitator part is opened and closed through the opening and closing door to solve a problem that requires considerable time in maintenance. It relates to an electrostatic precipitator that is easy to clean, so that it can be easily opened after withdrawal.

Electrostatic precipitators have been widely used as devices for removing particulate contaminants from industrial sites, and studies of single particulate contaminants have been conducted by many researchers.

However, with the recent trend in the United States, with the trend that the emission allowable concentrations for particulate matter, such as ultrafine particles, heavy metals, and white smoke, will be further strengthened, ultrafine dust, gaseous and liquid mist phases New dust collection and harmful gas removal technology for complex pollutants is required.

Currently, the annual standard for fine dust in Korea is expected to be strengthened from 70 to 50 μg / m ³ , but it is still higher than the US California standard of 20 μg / m ³ , and is expected to be strengthened in the future.

On the other hand, in the United States, it started to regulate the fine particles of PM (Particulate Matter) 2.5 from 1997, and announced that the standard will be strengthened from December 2005. Focusing on the most important issues.

Since 2010, the emission allowance standards for power plants, incinerators, etc. have been greatly strengthened, and emission allowance standards for new high-tech industrial facilities such as semiconductor manufacturing facilities and liquid crystal display devices (LCDs) have been strengthened.

Even in processes that use various hazardous chemicals, such as semiconductor processes, fine dust, mist, and various human harmful chemicals that are difficult to remove in existing dust collectors are discharged as exhaust gases.

In order to remove contaminants attached to the dust collecting plate in the electrostatic precipitator used for the purification of these harmful exhaust gases, the contaminants attached to the dust collecting plate are removed through a rapping process.

However, the biggest problem in the process of removing contaminants of the conventional electrostatic precipitator is the problem of re-scattering of dust when mechanical impact is applied to the dust collecting plate, discharge electrode, discharge pin, etc. As a result, how to prevent the re-scattering of the dust is a design problem, and the dust collector manufacturers are struggling. In particular, it is necessary to prevent maximal re-scattering by adopting a suitable crushing device according to the type of dust. Thus, there is a problem that re-scattering problems and damage to the parts are not clearly solved.

In addition, in the case of a medium-sized or small-sized electrostatic precipitator that is not large-sized, metal plates such as thin aluminum are mostly used. In the case of using a thin plate as described above, dusts are collected between narrow gaps, and the metal plates are There is a problem in that it is difficult to clean due to the narrow gap, and it takes a considerable amount of time to maintain because it must be dried after cleaning.

The present invention uses a metal plate such as thin aluminum. In a small electrostatic precipitator, when using a thin plate, dust is collected between the narrow gaps, and it is difficult to clean because the gap between the metal plates is narrow to clean the dust. Of course, since it must be dried after cleaning, the purpose of the present invention is to provide an electrostatic precipitator that is easy to clean and maintain by allowing the electrostatic precipitator to be opened after drawing out in order to solve the problem of taking considerable time in maintenance. have.

In addition, the present invention allows the electrostatic precipitator to be pulled out from the housing to solve the problems caused by the conventional crushing process in a method of removing contaminants from the electrostatic precipitator, thereby re-dispersing dust when applied to a dust collecting plate, discharge electrode, discharge pin, etc. It is an object of the present invention to solve the problems caused by the impact and the damage of the parts due to impact hitting.

The non-explanatory code N denotes a mesh.

The operation of the present invention configured as described above will be described together with the drawings.

First, looking at the process for assembly and other production of the present invention,

Unlike a conventional electrostatic precipitator, the dust collecting pipe 500 of the electrostatic precipitator 500 can use a relatively long product and has a merit that it can be installed even if the installation location is narrow because it is long in the vertical direction during installation.

Specifically, as illustrated in FIGS. 4 and 9, a pair of grip brackets 410 are vertically coupled while a semi-cylindrical dust collecting pipe 500 is coupled to the groove 400 of the grip bracket 410. Discharge tube 510, discharge pin 520, power supply device 530, insulator, which is a type of electrical dust collector 50, is formed before forming the dust collecting tube 500 of the cylindrical body, but before forming the dust collecting tube 500 of the cylindrical body. In step 540, the pair of grip brackets 410 are vertically combined to form the grip bracket unit 40.

6 and 8, the grip dust collecting unit 40 having the electric dust collecting unit 50 therein is opened in the same state as the opening / closing door 102 of the housing 10, and then the grip bracket unit The lower end of the (40) is slidingly coupled into the interior of the bottom guide bracket 20 between the second guide plates 211, that is, the second guide member 210, wherein the upper part of the housing 10 is the tom guide bracket 30 The first guide plate 311, that is, the first guide member 310 is automatically coupled and sliding to be accommodated in the housing 10, and a plurality of grip bracket units 40 can be stored in the same way, and largely Accordingly, a plurality of grip bracket units 40 can be stored.

When the opening / closing door 102 is fastened in the above-described state, the pipes are connected to the inlet 100 and the outlet 101, respectively, as shown in FIG. 10, and when power not shown in the drawing is supplied, dust is generated. After being introduced through the inlet 100, filtered into the inlet hole 300 in a state primarily filtered by the filter network N, and then burned by the electric dust collector 50, sludge and the like are dropped into the dust container 103 and purified air Is to communicate with the inside of the partition wall 106 provided on the upper surface of the support bar 105 through the upper side of the leakage preventing wall 104 through the opening of the lower portion of the frame 200 to discharge to the discharge port 101.

At this time, the outflow prevention wall 104 serves to prevent dust contained in the dust container 103 from being scattered and discharged to the outlet 101.

The core of the present invention is to make it easy and reliable in cleaning dust residues attached to discharge electrodes 510, discharge pins 520, etc., which are components of the electrostatic precipitator 50 according to long-term use,

Specifically, as shown in FIGS. 6 to 9, after opening and closing the door 102 for cleaning after a long period of use, the grip bracket unit 40 is provided with a first guide member 310 and a second guide member. Withdrawal from 210, the stop protrusion 421 of the fixing plate 420 is attached to the fall prevention plate 107 of the housing 10 so that the grip bracket unit 40 does not fall off from the housing 10 at this time. It is intended to be no longer withdrawn, and after the withdrawal as described above, when the grip bracket 410 is opened by releasing the fastening portion 411 provided in front of the grip bracket 410, the cylindrical dust collecting pipe 500 is opened. As it is separated into a semi-cylindrical body, the inside of the electrostatic precipitator 50 is completely exposed. After cleaning in this state, the fastener 411 is fastened, and then the grip bracket unit 40 is moved into the housing 10 as described above. You just have to store it.
