Abstract

The present invention relates to a liquid dust collector with a dual adsorption structure. The liquid dust collector includes: a drying and dust collecting member (110) which dries wet debris suctioned from the outside while adsorbing dust with large particles from the dried debris; and a dual adsorption member (130) including an inner adsorption unit (131) which primarily adsorbs dust while lowering the debris which has passed through the drying and dust collecting member (110) to a lower portion of a central passage (133), and an outer adsorption unit (141) which secondarily adsorbs dust from the debris which has passed through the inner adsorption unit (131) by using an adsorption filter (144). Drying and adsorption are performed simultaneously in a drying and dust collecting body, and air from which dust has been removed by the inner adsorption unit and the outer adsorption unit installed in a dual structure can be discharged to the outside. After dust is primarily removed by the inner adsorption unit, remaining dust can be secondarily removed by the outer adsorption unit. Since the inner adsorption unit is installed inside the outer adsorption unit, the overall size of the dust collector can be minimized. By installing a plurality of dust collectors in a dust emission zone, dust in the dust emission zone can be removed.

Description

Liquid dust collector with double adsorption structure}

The present invention relates to a liquid dust collector with a double adsorption structure. More specifically, the present invention relates to a liquid dust collector with a double adsorption structure. More specifically, it not only improves dust collection efficiency by filtering powdery dust, etc. through a dust collector composed of a double adsorption port, but also periodically removes dust adsorbed on the dust collector. This relates to a liquid dust collector with a double adsorption structure that maintains the adsorption efficiency of dust, etc. over a long period of time.

In general, electrostatic precipitators have been widely used as devices to remove particulate contaminants generated in industrial sites, and research on single particulate contaminants has been conducted by many researchers.

However, with the recent trend in the United States to further strengthen the emission concentration limits for new trace harmful particulate matter such as ultrafine dust particles, heavy metals, and white smoke, ultrafine dust and gaseous and liquid mist New dust collection and harmful gas removal technologies for complex pollutants are required.

Currently, the domestic fine dust annual standard is scheduled to be strengthened from 70 to 50 μg/m3, but this is still higher than the California standard of 20 μg/m3 and is expected to be further strengthened in the future.

Meanwhile, in the United States, starting with the regulation of fine particles of PM (Particulate Matter) 2.5 in 1997, it was announced that the standards would be further strengthened starting in December 2005, and the fine dust reduction measures announced in 2006 were the most important air environment policy in the United States. We are focusing on this as an important issue.

In Korea, since 2010, emission standards for workplaces such as power plants and incinerators have been significantly strengthened and emission charges have been revised, and emission standards for new high-tech industrial facilities such as semiconductor manufacturing facilities and liquid crystal displays (LCDs) have been strengthened.

Even in processes that use various hazardous chemicals, such as semiconductor processes, fine dust, mist, and various chemicals harmful to the human body, which are difficult to remove with existing dust collection devices, are emitted as exhaust gases.

Wet scrubbers are used to purify these harmful exhaust gases, but due to limitations in treatment efficiency and structural problems, a reduction technology using an effective wet electrostatic precipitator is being developed and applied.

A wet electrostatic precipitator (WESP) is composed of a discharge electrode, a dust collection plate, and a high voltage application device that make up a dry electrostatic precipitator, plus a cleaning water supply device and a circulation device.

Instead of a lapping process to remove contaminants attached to the dust collection plate in a dry electrostatic precipitator, washing water is supplied to the dust collection plate in a wet electrostatic precipitator to remove the attached contaminants.

Wet electrostatic precipitators show excellent performance in controlling the emission of particles and gaseous pollutants such as sub-micron fine particles, heavy metal particles, mist, fume, dioxin, and furan.

While the dust collection efficiency of pollution prevention equipment such as fabric filters or dry electrostatic precipitators is sensitive to the physical and chemical properties of the particles to be removed, wet electrostatic precipitators can be applied to pollution prevention equipment in various areas, and the target particles It is effective in removing submicron particles regardless of their physical and chemical properties.

However, in a general metal plate-type wet electrostatic precipitator, the cleaning water tends to be in the form of beads due to the initial imperfection of the dust collection plate installation and the surface tension of the cleaning water and the dust collecting plate, which causes dry spots where the cleaning water does not exist on the dust collecting plate. Its presence causes particles to build up and reduces current, which is the main cause of overall efficiency.

The method of spraying cleaning water on the dust collection plate to remove such dry spots generates mist by spraying the cleaning water, which acts as a conductor between the discharge electrode and the dust collection electrode, causing a spark-over phenomenon that destroys the electric field. do.

When operating a wet electrostatic precipitator, the spark over phenomenon causes a decrease in dust collection efficiency, causing a problem of blue haze occurring when discharging at the rear of the pollution prevention equipment.

In order to prevent this spark-over phenomenon, the applied voltage must be reduced or the application of high voltage must be stopped when spraying cleaning water, which reduces the efficiency of the wet electrostatic precipitator and causes the problem that continuous operation cannot be guaranteed.

In addition, in the conventional wet electrostatic precipitator, even if cleaning water is sprayed, contaminants are not smoothly removed due to the problem of the dust collection plate drying between spray cycles, and the sprayed cleaning water generates a mist phenomenon and is not sprayed evenly throughout the entire dust collection pipe, causing the dust to collect. There was a problem in that it was very inefficient in removing contaminants because the water film layer could not be formed evenly throughout the entire tube.

For example, Patent Document 1 below discloses a 'composite wet dust collector using vortex phenomenon and spraying'.

The composite wet dust collector based on the vortex phenomenon and spray according to Patent Document 1 below includes a dust collection tank in which a treatment liquid is stored inside, a sludge discharge port at the bottom, and a purified air discharge port at the top, and dust collection tank is sprayed into the dust collection tank, Dust-collecting air injection means for spraying dust-collected air in a vortex shape along the circumferential direction of the dust-collecting tank, and spraying the treatment liquid stored in the dust-collecting tank into the inside of the dust-collecting tank, while being close to the dust-collecting air sprayed by the dust-collecting air spraying means. A processing liquid injection means that sprays treatment liquid in the same direction as the dust-filled air and breaks the dust-dusted air into small pieces by coming into contact with the dust-dusted air, and dust-collecting air installed below the purified air outlet of the dust collection tank and rising toward the purified air outlet collide. A perforated plate that breaks into small pieces and extends the residence time, and the treatment liquid inside the dust collection tank is sprayed from the top of the perforated plate toward the bottom, so that the dust contained in the vacuum air rises through the perforated plate.
