Description

Wet-dry type electric precipitation with cleaner

The present invention relates to a wet-dry electric dust collector equipped with a washing means, and more particularly, various harmful substances contained in the gas, such as particulate matter, gaseous substances, The present invention relates to a wet-dry electric dust collector equipped with a cleaning means capable of more effectively removing household odors, etc. from gas and effectively cleaning contaminants remaining inside in the process of removing harmful substances.

In general, a dust collector is installed in a place where a lot of dust is generated, and is an air purifying device to prevent air pollution caused by dust by collecting floating dust contained in indoor air, purifying it with clean air, and discharging it to the outside.

Usually, dust collectors suck in various kinds of dust, such as dust and foreign substances, through the inlet, filter it in the filter bag installed inside the dust collector housing, and discharge the clean air from which the dust has been removed to the outside through the outlet, while the dust collected in the filter bag By operating the compressor, the compressed air is sprayed back to the filter bag at regular time and intervals through the spray nozzle tube, so that the dust attached to the outer surface of the filter bag is removed and the dust collected through the lower dust ejector is treated. consists of

Meanwhile, dust is classified into total uspended particles (TSP) with a particle size of less than 50 μm and particulate matter (PM) with a very small particle size. Fine dust is further divided into fine dust with a diameter of less than 10 μm (PM10) and fine dust with a diameter of less than 2.5 μm (PM2.5). If PM10 is about 1/5~1/7 smaller than the diameter of human hair (50~70μm), PM2.5 is very small enough to be only about 1/20~1/30 of that of a human hair.

In the case of a general dust collector, it is very difficult to collect the fine dust in a filter bag mounted on the dust collector, and an electric dust collector is mainly used to effectively filter the fine dust.

However, these electrostatic precipitators have high filtration efficiency for particulate matter, but the filtration efficiency of gaseous substances and odors is not very high. was not efficient.

As part of simultaneously collecting such odors, an additional installation of an activated carbon filter inside the electrostatic precipitator may be considered.

In addition, such an electrostatic precipitator needs to periodically clean the contaminants accumulated therein. For this purpose, it is not easy to disassemble and wash various components constituting the electrostatic precipitator one by one.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This example is provided to more completely explain the present invention to those of ordinary skill in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. Detailed descriptions of well-known functions and configurations determined to unnecessarily obscure the gist of the present invention will be omitted.

As shown in Figs. 1 to 2, the electric dust collector according to the present invention is selectively coupled to the electric dust collecting unit 1 and the electric dust collecting unit 1 to clean the inside of the electric dust collecting unit 1, the washing unit 2 It can be defined as including

First, the configuration of the electric dust collecting unit 1 will be described in detail with reference to the accompanying drawings.

The electric dust collector 1 is responsible for removing various harmful substances contained in the polluted gas by sucking the external polluting gas.

To this end, the electric dust collecting unit 1 may be defined as including a case 10 , an electrode unit 20 , a packing member 40 , and a water spray unit.

First, the case 10 constitutes the overall appearance of the electrostatic precipitator, and accommodates components such as the electrode part 20 , the packing member 40 , and the water spray part inside.

In particular, a diaphragm 11 is provided inside the case 10 to divide the interior into a pre-treatment space 13 and a post-treatment space 14, and the inner space is divided into a pre-treatment space 13 and a post-treatment space 14, respectively. becomes binary.

In addition, an opening 70 for opening the post-processing space 14 by a predetermined area may be formed through the case 10 . The cleaning unit 2 to be described later may be drawn out into the post-treatment space 14 through the opening 70 .

The cover 80 serves to open and close the opening 70, and when the electric dust collecting unit 1 is used alone, the cover 80 closes the opening 70 in the post-processing space 14 It has a structure in which water, gas, etc. in operation do not leak to the outside. On the contrary, when the washing unit 2 is coupled to the electric dust collecting unit 1, the cover 80 opens the opening 70 to the washing unit ( 2) has a structure that can accommodate it.

The cover 80 may have an insertion protrusion 81 inserted to a predetermined depth through the opening 70 on a surface adjacent to the case 10 to protrude, and the post-processing space 14 may be formed by the insertion protrusion 81 . ) of the packing member 40 accommodated in the opening 70 can be limited to some extent.

A plurality of openings 70 are perforated in a circular shape to pass the brush member 100 of the cleaning unit 2 to be described later.

On the other hand, even if the cover 80 is removed and the opening 70 is exposed to the outside, the packing member 40, water, etc. accommodated in the post-treatment space 14 through the opening 70 do not easily flow out to the outside. have a closed structure.

To this end, as shown in FIG. 13 , a sealing film 71 is formed on the inner wall surface of the post-processing space 14 , and a rubber ring 72 is formed at each corresponding position of the opening 70 in the sealing film 71 . ) has a structure in which a sealing hole 73 that is elastically expanded or closed is formed.

More specifically, the sealing film 71 is made of an elastic material film-like member that can be stretched and compressed freely, and a rubber ring 72 is installed around the sealing hole 73 to close the sealing hole 73 by tightening it. . At this time, when the brush member 100 to be described later is introduced into the closing hole 73 , the rubber ring 72 is elastically deformed to correspond to the brush member 100 , and the sealing member 73 is expanded correspondingly.

That is, in the state in which the brush member 100 does not pass through the sealing hole 73 , the opening 70 is always sealed by the sealing film 71 , so even if the cover 80 is removed, the post-processing space 14 . It is possible to effectively suppress the backflow of water, gas, etc. to the outside through the opening 70 as well as the packing member 40 accommodated in the .

In addition, in order to further improve the sealing effect, the first magnetic sealing member 74 in the form of a closing band is surrounded on the outside of the case 10 around the opening 70, and the first magnetic sealing member is on the cover 80. The second magnetic sealing member 82 in the form of a closing strip having a polarity different from that of (74) is surrounded, and by the bonding of the first magnetic sealing member 74 and the second magnetic sealing member 82, the cover 80 is formed in the case ( 10) It may have a structure coupled to the phase.

Accordingly, the cover 80 can be more easily attached to and detached from the case 10, and since the inner space between the first magnetic sealing member 74 and the second magnetic sealing member 82 is sealed (73), the external and the passage connecting the post-processing space 14 can be configured more airtightly.

The gas to be filtered may pass through the pre-treatment space 13 and the post-treatment space 14 of the case 10 sequentially and then be purified and discharged to the outside.

A communication port 12 for communicating the pre-treatment space 13 and the post-treatment space 14 is provided at the lower portion of the diaphragm 11 to transfer the gas primarily filtered in the pre-treatment space 13 to the post-treatment space 14 inlet to the side.

An inlet 15 and an outlet 16 communicating with the pre-processing space 13 and the post-processing space 14 are respectively formed at an upper portion of the case 10 .

The inlet 15 serves as an inlet for sucking the external pollutant gas into the pretreatment space 13 , and the outlet 16 serves as an outlet 16 for discharging the purified gas on which the filtration process has been completed inside the case 10 . .

The inlet 15 and the outlet 16 may be formed in the form of a bellows tube, and thus the length and angle adjustment of the inlet 15 and the outlet 16 may be easily implemented.

A suction fan 17 for circulating the gas inside the case 10 may be installed at at least one of the inlet 15 and the outlet 16 .

In this embodiment, it is assumed that the suction fan 17 is installed at the distal end of the outlet 16 , and when the suction fan 17 is driven, the pre-treatment space 13 and the post-treatment space 14 are connected to the communication port 12 . ), so that the suction power of the suction fan 17 can reach the suction port 15 without unreasonableness, and the polluted gas can be sucked into the pretreatment space 13 through the suction port 15 . Subsequently, the gas sucked into the pretreatment space 13 may be sucked up to the outlet 16 and discharged to the outside.

In the pre-treatment space 13, the inhaled pollutant gas is filtered in a dry method to remove various harmful substances contained in the polluted gas, and in the post-treatment space 14, the pollutant that has not been filtered according to the dry method in the pre-treatment space 13 in the post-treatment space 14 The material may be filtered again wet.

To this end, the electrode unit 20 is installed in the pre-treatment space 13 to collect particulate matter such as dust contained in the gas in a dry manner, and in the post-treatment space 14 , water is added to the gas passing through the pre-treatment space 13 in the post-treatment space 14 . to dissociate the contaminants from the gas.

The electrode unit 20 is installed in the pre-treatment space 13 and collects dust by corona-discharging the gas sucked into the pre-treatment space 13 .

The electrode part 20 in this embodiment is largely illustrated as including a bracket 21 , a discharge electrode 22 , a counter electrode module 24 , and a cradle 25 .

First, the discharge electrode 22 receives a high voltage from the insulator 23 so that corona discharge can be generated, so that the dust contained in the gas can be ionized.

The dust ionized through the discharge electrode 22 loses insulation and is collected in a counter electrode module 24 to be described later.

The counter electrode module 24 may be formed in a rectangular cylindrical shape that surrounds the discharge electrode 22 from all sides, and may be divided into two pairs in the front and rear directions.

For maintenance, one side of the counter electrode module 24 may be removed to open the discharge electrode 22 , and foreign substances adhering to the vicinity of the discharge electrode 22 and the counter electrode module 24 may be removed.

When the gas passes between the discharge electrode 22 and the counter electrode module 24 , corona discharge may occur and dust contained in the gas may be collected.

Specifically, corona discharge is generated around the discharge electrode 22 by the insulator 23 , and negative (-) charges are transferred from the discharge electrode 22 to the counter electrode module 24 .

In this process, the dust contained in the gas absorbs a negative (-) charge and ionization takes on a negative (-) charge occurs, and the counter electrode module 24 is opposite to the charge generated by the discharge electrode 22 . Since it has a polarity charge, it becomes positive (+). Therefore, the dust bearing the negative (-) charge adheres to the counter electrode module 24 bearing the positive (+) charge, the dust is collected, and the dust-removed gas passes through the electrode unit 20 and then communicates. It may be sucked into the post-treatment space 14 through the sphere 12 .

The bracket 21 is configured to converge the upper end and the lower end of the counter electrode module 24 divided into a pair, respectively, and the bracket 21 itself may be attached and installed in a place in the pretreatment space 13 .

The cradle 25 is installed on the upper end of the counter electrode module 24 to support the upper end of the discharge electrode 22 .

It is revealed that the structure of the electrode part 20 as described above can be variously modified from the known ones in a line capable of performing corona discharge, and detailed description thereof will be omitted.

When the dust collected by the electrode unit 20 falls under its own weight at the lower portion of the electrode unit 20 , a dust container 18 for collecting and storing the fallen dust may be provided.

The dust container 18 may have a structure that can be pulled out in the form of a drawer from the lower end of the case 10 .

Next, in the post-treatment space 14 , the inhaled gas is reacted with water in order to separate harmful substances that have not been captured by the corona discharge from the gas. At this time, as a configuration for increasing the contact efficiency of the sprayed water and the gas, the packing member 40 is used.

The packing member 40 may have a porous structure in which a plurality of spokes 41 are radially formed inside the cylindrical body 41 as shown in FIG. 7 , and the packing member 40 is a post-processing space. (14) is randomly charged.

Accordingly, the packing member 40 passes the gas introduced from the pre-treatment space 13, and generates a flow resistance in the passing gas to reduce the flow rate of the gas, and in addition, the gas in the area filled with the packing member 40 It works to spread the range of

That is, as the gas flows between the packing member 40 or the adjacent packing members 40, the flow rate is reduced and at the same time, the packing member 40 can be widely spread throughout the filled area.

A support net 19 in the form of a net for supporting the packing member 40 may be installed in the post-processing space 14 . The support network 19 supports the packing member 40 in a line that does not interfere with the flow of water or gas, and a plurality of packing members 40 may be stacked on top of the support network 19 .

The water spray unit acts to spray water to the upper portion of the packing member 40 , and when water is sprayed toward the packing member 40 , the gas passing through the packing member 40 or the gas moored in the packing member 40 is water. may react in contact with

In the water spray unit, the spray nozzle 31 installed on the upper part of the packing member 40, the pump 32 for pumping water from the tank 34 in which water is stored, and the water pressurized from the pump 32 are transferred, and the It may be exemplified as including a connection pipe 33 connecting between the pump 32 and the injection nozzle 31 .

The spray nozzle 31 has a variety of shapes, such as a short-distance type, a long-distance type, a wide-angle type and a conical type, a circular type and a sector type, a rotation type and a sprinkler type, a hydraulic type, and a double-fluid type, in a line that can atomize water and spray it. All can be applied.

The lower portion of the post-treatment space 14 may be composed of a tank 34 in which a certain amount of water is stored, and the pump 32 pumps the water stored in the tank 34 and supplies it to the injection nozzle 31 side. do.

The jet nozzle 31 jets water downward from the tank 34 . In this process, the water-soluble gas and odor particles introduced from the pretreatment space 13 collide with water while moving upward in the direction opposite to the water, and harmful substances contained in the gas, for example, water-soluble gas and odor particles, are decomposed into water. can be

In addition, the water sprayed to the packing member 40 flows through between the packing members 40. At this time, the water is entangled with the gas flowing between the packing members 40 in the opposite direction to the spraying to purify the gas. do.

In other words, in the region where the packing member 40 is stacked, the contact area and contact time between the gas and water is increased, so that the physical contact between the gas and water can be effectively induced.

Therefore, it is possible to increase the dust collection efficiency by allowing the various harmful substances contained in the gas to be sufficiently filtered.

The water passing through the packing member 40 may be returned to the tank 34 disposed under the packing member 40 . That is, the water sprayed from the spray nozzle 31 passes through the packing member 40 and then returns to the tank 34 again, and the pump 32 pumps the returned water back to the spray nozzle 31 side. Water is cycled through a cycle.

In this process, if the quality of water is reduced to a certain level, it has a structure that can be replaced with the existing clean water.

To this end, a water discharge pipe 35 may be branched in the connection pipe 33 , and a control valve 38 may be installed in at least one of the connection pipe 33 and the water discharge pipe 35 .

That is, when the water in the tank 34 is to be discharged to the outside, the control valve 38 is controlled to close the connection pipe 33 , and then the pump 32 is driven to pump the contaminated water contained in the tank 34 . When this is done, the contaminated water flows along the connection pipe 33 and flows toward the water discharge pipe 35 at the branching point to the water discharge pipe 35 and can be drained to the outside.

Separately, a water injection pipe 36 for forcibly injecting water into the tank 34 may be provided on the outside of the case 10 .

In addition, a water level gauge 37 may be installed around the water injection pipe 36 so that the water level accommodated in the tank 34 can be visually checked from the outside of the case 10 .

Due to such a structure, the process of disassembling the separate case 10 to replace the water contained in the tank 34 can be omitted, and thus, maintenance work for water quality management can be performed more easily and conveniently.

A demister 60 for blocking moisture contained in the gas is mounted on the upper portion of the injection nozzle 31, and a catalyst member 50 for removing ozone generated during corona discharge is mounted on the upper portion of the demister 60. can Since the catalyst member 50 can be referred to from known technologies in a line capable of removing ozone through a catalytic reaction, a detailed description thereof will be omitted.

On the other hand, around the communication port 12, a backflow prevention cap 12a in the form of a cap may be formed to protrude toward the post-processing space 14 side.

The backflow prevention cap 12a is a member serving as a blocking film preventing water flowing from the post-treatment space 14 from flowing into the pre-treatment space 13, and if water falling from the post-treatment space 14 is When it flows into the pre-treatment space 13 through (12), there is a risk that the electrode part 20 is short-circuited and burned.

Hereinafter, the filtering process of harmful substances according to the operation of the electric dust collector 1 will be described as an example.

First, when the suction fan 17 is driven, a negative pressure is formed throughout the pre-treatment space 13 and the post-treatment space 14 , so that the gas around the suction port 15 is sucked into the pre-treatment space 13 through the suction port 15 . do.

The gas sucked in through the suction port 15 passes through the pretreatment space 13 from the top to the bottom, and at this time, it passes between the discharge electrode 22 of the electrode part 20 and the counter electrode module 24 and is ionized. Accordingly, the dust contained in the gas that has passed through the electrode unit 20 is attached to the counter electrode module 24 and separated from the gas.

The gas that has passed through the electrode unit 20 and has undergone the primary filtration process is introduced into the post-treatment space 14 through the communication port 12 .

The gas introduced into the post-treatment space 14 passes through the packing member 40 while ascending toward the outlet 16 .

The gas passing through the packing member 40 passes between the packing members 40 , the flow rate is reduced, and spreads over the entire area of the packing member 40 .

At the same time, the water sprayed from the injection nozzle 31 flows along the packing member 40 in a direction opposite to the suction direction of the gas, and is entangled with the gas to purify the gas.

Then, the water passing through the packing member 40 from the top to the bottom freely falls downward holding the decomposed contaminants and is collected in the tank 34, passes the packing member 40 from the bottom to the top and is continuously sucked The gas is again purified by the water in contact with the water being sprayed from the injection nozzle (31). In this process, most of the water-soluble gas or odor particles contained in the gas may be decomposed.

The gas that has passed through the packing member 40 is continuously ascended by the suction fan 17 and then is completely purified through the demister 60 and the activated carbon filter 50 and is flow-controlled so that it is discharged to the outside through the outlet 16. .

In summary, in the pretreatment space 13 , particulate matter and other low-solubility substances contained in the sucked gas are collected, and in the post-treatment space 14 , particulate matter and water-soluble gas that have not been captured in the pretreatment space 13 . , First, odors containing oil are decomposed with water. Therefore, the electrostatic precipitator according to the present invention can increase the removal efficiency of harmful substances from the gas by removing various harmful substances contained in the gas in stages, and further can effectively reduce the emission of harmful substances.

Hereinafter, the configuration of the washing unit 2 will be described in detail with reference to the accompanying drawings.

The washing unit 2 serves to wash the packing member 40 contaminated by various contaminants in the post-processing space 14 .

A large amount of contaminants may be attached to the surface of the packing member 40 while gas and water pass through, and if these contaminants are not properly removed, there is a problem in that the proper function of the packing member 40 cannot be exhibited.

Accordingly, in the present embodiment, the structure of the washing unit 2 that can wash the packing member 40 in the post-processing space 14 without separately extracting and washing the packing member 40 from the post-processing space 14 is provided. suggest

To this end, the washing unit 2 includes a plurality of brush members 100 inserted into the post-processing space 14 through the opening 70 opened by the cover 80 as shown in FIG. 14 , The plurality of brush members 100 are rotationally supported, and the carrier 200 is in close contact with the case 10 around the opening 70 and is installed on the carrier 200 and drives the plurality of brush members 100 to rotate. It may be exemplified as including a rotation driving unit.

Each of the plurality of brush members 100 is inserted into the post-processing space 14 by pushing the sealing hole 7. of the sealing film 71, and a packing member accommodated in the post-processing space 14 while rotating by a rotary driving unit ( 40) by applying physical friction to the surface of the packing member 40 to wash the contaminants.

At this time, since water is provided to the packing member 40 by the water spraying unit, the packing member 40 can be cleaned more effectively. Then, sewage generated when the packing member 40 is washed may be collected into the tank 34 .

Each of the plurality of brush members 100 has a pulley 112 integrally formed at one end and is installed at the other end of the washing shaft 110 and the washing shaft 110 having a brush 111 formed on the outer circumferential surface, and is thinner toward the end. It may be illustrated as including a head 120 having a conical shape.

The pulley 112 of the washing shaft 110 is accommodated in the carrier 200 and rotatably supported, and the brush 111 on the outer peripheral surface interlocks with the rotating washing shaft 110 to apply friction to the packing member 40. apply

The head 120 plays a role in securing the access path of the washing shaft 110 by disturbing the stacked packing members 40 in the process of inserting the washing shaft 110 into the post-processing space 14 .

At this time, since the head 120 is formed in a conical shape, resistance with the packing member 40 can be reduced while securing an access road.

In addition, one edge portion of the head 120 is rounded so that in the process of removing the cleaning portion 2, the packing member 40 naturally comes into contact with one edge of the head 120 and passes over the cleaning portion (2) is easier to remove.

On the other hand, the brush member 100 is installed in the direction symmetrical to each other inside the head 120, a part of the head 120 is exposed to the outside, while rotating in place, a pair of sliding contact with the packing member (40) It may further include a sliding roller 300 .

A pair of sliding rollers 300 make sliding contact with the packing member 40 in the process of coupling or removing the washing unit 2 to the electric dust collecting unit 1 so that the brush member 100 can see between the packing members 40 . It can be easily penetrated or removed between the packing members 40 .

The rotation driving unit may be variously implemented in a line capable of simultaneously driving the plurality of brush members 100 to rotate, and in this embodiment, for example, a belt ( 310), may be exemplified as including a motor 320 for rotating the belt 310 in an endless orbit, and a detailed description below will be omitted.

On the other hand, the carrier 200 is surrounded by a second magnetic sealing member 210 in the form of a closing strip having a polarity different from that of the first magnetic sealing member 74, the first magnetic sealing member 74 and the second magnetic sealing member ( It has a structure in which the carrier 200 is coupled to the case 10 by bonding of the 210 .

Accordingly, the cleaning unit 2 can be more easily attached to and detached from the case 10, and since the inner space between the first magnetic sealing member 74 and the second magnetic sealing member 210 is sealed, the cleaning unit 2 ) can effectively limit the outflow of water, etc. by configuring the passage connecting the outside and the post-treatment space 14 more airtight even in the coupled state.

As shown in FIG. 16, when the washing unit 2 is coupled to the electric dust collecting unit 1, the brush member 100 is inserted between the packing members 40 accommodated in the post-processing space 14, and in this state, the brush The member 100 is rotated to wash the packing member 40 around the brush member 100 .
