Description

Volatile organic compound adsorption system with activated carbon recycle with activated carbon dust collection exchanger

The present invention relates to an activated carbon recycling type volatile organic compound adsorption device having an activated carbon dust collector exchanger, which is equipped with an activated carbon dust collector exchanger to enable recycling of activated carbon that captures volatile organic compounds when work is performed in a closed space such as a painting facility for industrial equipment including automobiles and ships, thereby facilitating maintenance, improving the work environment, and preventing environmental pollution.

Korean Patent No. 10-0454427 comprises a separator that receives a hazardous gas and separates it into hazardous and non-hazardous components using activated carbon as a catalyst, a first purifier that receives activated carbon that has been separated through the separator and adsorbed/captured the hazardous components and decomposes the activated carbon using high-frequency microwaves, a second purifier that separately collects only the hazardous components such as ions, radicals, and unreacted gases separated from the activated carbon, mixes/dilutes nitrogen gas therein, and completely decomposes the hazardous components again using high-frequency microwaves, and a catalytic purifier that finally purifies the completely purified components; The regenerated activated carbon from which the hazardous substances are separated from the first purifier is collected and recycled in the separator, and at the same time, each purifier repeats the process of completely decomposing the electrons contained in the hazardous substances by exciting them with electromagnetic waves and a resonance phenomenon through high-frequency microwaves having a frequency band of 40 kHz to 5 GHz, thereby allowing only substances harmless to the human body to be emitted into the atmosphere. A high-efficiency hazardous gas purification device using microwaves and a purification method therefor are disclosed.

In addition, Korean Patent No. 10-0343804 discloses a VOC adsorption/desorption device for a painting booth and a method for regenerating an activated carbon filter, which effectively captures and adsorbs VOCs generated during long-term work by passing the VOCs through a multilayer filter formed in a grid shape with a stainless steel mesh uniformly filled with granular activated carbon and natural zeolite mixed in a ratio of 6:1 to 8:1, thereby preventing air pollution, and periodically heats the activated carbon filter to desorb and burn the VOCs captured in the granular activated carbon, thereby enabling the activated carbon filter to be reused.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

Figure 1 shows the entire system of the present invention.

Referring to FIG. 1, the volatile organic compound adsorption device of the activated carbon recycling type equipped with an activated carbon dust collector exchanger of the present invention is configured to include a volatile organic compound adsorption device (100) as an adsorption means for capturing and purifying hazardous substances, an activated carbon dust collector exchanger (200) as a dust collector exchange means for capturing hazardous substances generated in the process of collecting adsorbed substances treated in the adsorption means, and an activated carbon regeneration unit (300) as a regeneration means for removing hazardous substances adsorbed in the dust collector exchange means.

Hereinafter, the volatile organic compound adsorption device (100) and the activated carbon regeneration unit (300) of the present invention will be specifically described, focusing on the activated carbon dust collector exchanger (200).

The activated carbon dust collector (200) of the present invention collects pellet-shaped activated carbon, which has a reduced adsorption capacity due to saturated adsorption material, by suction from the volatile organic compound adsorption device (100), while simultaneously capturing hazardous substances generated during collection and sending the activated carbon with the hazardous substances captured to the activated carbon regeneration unit (300).

As shown in Fig. 2, the activated carbon dust collector (200) is configured to include a suction means section (210), a collection means section (230), and a dust collector section (250).

The suction means (210) sucks activated carbon with harmful substances adsorbed thereon from the activated carbon purification unit (40) of the volatile organic compound adsorption device (100).

The above suction means (210) is detachably connected to a high-pressure hose (261) that injects high-pressure air toward the collection means (230), and the high-pressure hose (261) supplies high-pressure compressed air from an air compressor (260) to the collection means (230) to generate an auxiliary vacuum suction negative pressure for taking out activated carbon from the activated carbon purification unit (40), thereby vacuum-sucking the harmful substance-adsorbing activated carbon of the activated carbon purification unit (40).

The above high-pressure hose (261) is equipped with an opening/closing valve (262) to control the high-pressure air supplied to the collection means (230).

Of course, the above high pressure hose (261) may be formed in the first connecting pipe (P1).

The collection means unit (230) is connected to the suction means unit (210) via a flexible first connecting pipe (P1) and receives the harmful substance adsorbing activated carbon sucked from the activated carbon purification unit (40).

The above collection means (230) is composed of a main body (231), a cap (232), and a collection net (234).

The main body (231) is formed so that a space is formed in which the first connecting pipe (P1) is connected to collect the harmful substance adsorbing activated carbon, and is opened upward from the space in which the harmful substance adsorbing activated carbon is collected.

The cap (232) is detachably connected to the upper part of the main body (231).

A viewing window (235) is formed in the cap (232) above so that the state of the hazardous substance adsorbing activated carbon being collected in the collection net (234) can be observed, and the second connecting pipe (P2) is connected in the center so that the hazardous substances flying from the hazardous substance adsorbing activated carbon collected in the collection net (234) can be discharged by the vacuum suction action of the dust collection unit (250).

The above viewing window (235) is preferably formed of reinforced plastic or reinforced glass.

A connecting pipe (233) protruding from the outer wall and the inner wall is formed on the side wall of the main body (231). The first connecting pipe (P1) is connected to the outer connecting pipe (233a) protruding from the outer wall, and a collecting net (234) for collecting harmful substance-adsorbing activated carbon flowing in through the first connecting pipe (P1) is connected to the inner connecting pipe (233b) protruding from the inner wall.

The above collection net (234) is formed as a mesh-shaped bag in the shape of a bag and can be detachably fixed by tying it to the inner connecting tube (233b) with a string.

When the hazardous substance adsorbing activated carbon is collected in the collection net (234) and the collection net (234) is separated from the connecting pipe (233b) to transport the hazardous substance adsorbing activated carbon to the activated carbon regeneration unit (300), a large amount of hazardous substances fly away and pollute the working environment. However, the flying hazardous substances can be captured and removed by the vacuum suction action of the dust collection means unit (250) connected to the cap (232) of the collection means unit (230) and the second connecting pipe (P2).

As shown in Fig. 2, the collection means (230) is connected to the dust collection means (250) through a second connecting pipe (P2).

The above dust collection means unit (250) is connected to the above collection means unit (230) by a flexible second connecting pipe (P2) and is composed of a cyclone dust collector (251) that generates a vacuum suction negative pressure for sucking the hazardous substance adsorbing activated carbon into the suction means unit (210) and a vacuum suction negative pressure for separating the hazardous substance from the hazardous substance adsorbing activated carbon collected in the collection means unit (230).

The cyclone dust collector (251) is composed of a driving motor (252), a cyclone body (253), a lower dust collector (254), and an upper filter net (255).

The driving motor (252) is detachably connected to the cyclone body (253) with a toggle clamp (not shown).

The cyclone body (253) is composed of an outer cylinder (253a) formed in a cylindrical shape and an inner cylinder (253b) formed in a conical shape with a cross-section that is narrow from top to bottom.

The lower part of the inner tube (253b) is opened so that dust containing fine hazardous substances can rise into the inner tube (253b), and the dust particles of hazardous substances flowing in from the collection means (230) are separated by centrifugal force due to the suction negative pressure of the driving motor (251).

The lower dust collector (254) is detachably connected to the lower portion of the cyclone body (253) so that harmful dust particles separated by centrifugal force in the cyclone body (253) can be deposited downward.

The above lower dust collector (254) can be detachably connected to the cyclone body (253) with a toggle clamp (not shown).

In addition, the lower dust collector (254) has a connecting portion (254a) formed as an annular step in which the outer tube (253a) of the cyclone body (253) is received at the upper portion, so that the outer tube (253a) of the cyclone body (253) is detachably connected to the lower dust collector (254).

The upper filter net (255) surrounds the lower part of the driving motor (252) at the upper part of the inner tube (253b) of the cyclone body (253), and can separate and filter fine harmful dust particles to prevent them from leaking to the outside.

Accordingly, as air containing hazardous substances is drawn into the cyclone body (253) by the suction negative pressure of the driving motor (252), the hazardous substances and air rotate in a spiral direction in the space between the outer tube (253a) and the inner tube (253b) to form a downward cyclone airflow. At this time, the hazardous substances and air are separated by the centrifugal force of the cyclone airflow that is generated, and the relatively heavy dust precipitates into the lower dust collector (254), and the hazardous substances in the form of fine particles that do not precipitate rise into the inner tube (253b) through the open space at the lower end of the inner tube (253b).

This activated carbon dust collector (200) removes activated carbon whose adsorption capacity has been reduced due to saturation of the harmful substances adsorbed in the activated carbon purification unit (40) of the volatile organic compound adsorption device (100), removes dust and harmful substances from the activated carbon purification unit (40), sends it to a separate activated carbon regeneration unit (300) for regeneration, and then returns it to the activated carbon purification unit (40) to perform the capture of harmful substances and the purification of harmful gases.

At this time, the activated carbon dust collector (200) removes the activated carbon with reduced adsorption capacity from the activated carbon purification unit (40), and when the filter net (254) is removed from the activated carbon dust collector (200) to transport or discard the hazardous substance adsorbed activated carbon collected on the filter net (254) to the activated carbon regeneration unit (300), the flying hazardous substances are captured and removed by the vacuum suction action of the dust collector unit (250), thereby preventing the flying fine hazardous substance dust particles from leaking out to the outside, thereby improving the health of workers and the working environment.

The collection net (234) from which the hazardous substance adsorbing activated carbon is collected is separated from the connecting pipe (233b) and transferred to the activated carbon regeneration unit (300) to regenerate the hazardous substance adsorbing activated carbon.

The activated carbon regeneration unit (300) is a device that effectively regenerates activated carbon with reduced adsorption capacity after use so that it can be used repeatedly by applying physical, chemical, and biological treatments to the collected hazardous substance adsorption activated carbon to remove hazardous adsorption substances adsorbed on the surface and pores of the activated carbon and thereby restore the original adsorption capacity.

The above activated carbon regeneration unit (300) receives activated carbon captured by the activated carbon dust collector (200), removes harmful substances adsorbed on the activated carbon, thereby restoring the harmful substance adsorption capacity, and re-supplies the activated carbon with restored harmful substance adsorption capacity to the activated carbon purification unit (40) of the volatile organic compound adsorption device (100), thereby enabling it to be reused in the process of capturing and purifying harmful substances including volatile organic compounds (VOCs) and fine dust generated in the painting facility.

The above volatile organic compound adsorption device (100) captures and purifies harmful substances generated in the facility using activated carbon regenerated in the activated carbon regeneration unit (300) or newly supplied activated carbon, and then discharges purified air.

That is, as illustrated in FIGS. 4 to 7, the volatile organic compound adsorption device (100) captures and purifies harmful substances including volatile organic compounds (VOCs) and fine dust and harmful gases generated in a facility where painting work is performed using activated carbon in an activated carbon purification unit (40) and then discharges the purified air. For example, the facility unit refers to a facility where work is performed in a closed space, such as a painting facility for an automobile or a ship, and where harmful air after the work is discharged through a harmful air discharge unit.

As shown in FIGS. 4 to 6, the volatile organic compound adsorption device (100) of the present invention for recycling includes a body frame (10), an air inlet (D_In), a driving fan (20), a pocket filter unit (30), an activated carbon purification unit (40), and a purified air discharge unit (D_Out).

As illustrated in Fig. 4, the body frame (10) forms the skeleton of the device and supports the components. It may be composed of a metal frame, a metal panel, or a skeleton made of plastic material.

As illustrated in Fig. 4, the air inlet (D_In) guides air containing harmful gases discharged from a facility, such as a paint facility for an automobile or a ship, to the lower portion of the body frame (10). The air inlet (D_In) may be a discharge pipe (discharge duct) connected to a portion of the facility that discharges harmful air, or a space formed at the lower portion of the body frame (10) connected thereto.

As shown in Fig. 4, the driving fan (20) is installed on the upper part of the body frame (10), and causes the air from the lower part to move upward through the pocket filter part (30) and the activated carbon purification part (40), and discharges the purified air to the air discharge part (D_Out).

On both sides of the driving fan (20) at the top of the activated carbon purification unit (40), an upper side activated carbon purification unit (50) is formed.

As shown in Fig. 4, the driving fan (20) is rotated by the driving motor and provides power (pressure) to suck in harmful air from the top, thereby causing the harmful air to pass through the air inlet (D_In) → pocket filter unit (30) → activated carbon purification unit (40) → upper side activated carbon purification unit (50) → air discharge unit (D_Out).

As shown in FIGS. 4, 5 (a, b, c), and 6 (a, b, c, d), a pocket filter unit (30) is provided at the lower portion of the body frame (10) and primarily purifies air introduced through the air inlet unit (D_In) through the pocket filter (31). Details regarding the pocket filter unit (30) will be described later.

As shown in FIGS. 4 and 5 (a, b, c), the activated carbon purification unit (40) purifies air passing through the pocket filter unit (30) with activated carbon. Details regarding the activated carbon purification unit (40) will be described later.

As shown in Fig. 4, the purified air discharge unit (D_Out) discharges purified air to the outside by passing through the activated carbon purification unit (40).

<Activated carbon purification unit, inner and outer cylinder structure>

As shown in FIGS. 4 and 5 (a, b, c), the activated carbon purification unit (40) comprises an outer tube (41) having uniformly formed air intake holes (41-1), an inner tube (42) located in the inner space of the outer tube (41) and having uniformly formed air passage holes (42-1) and forming an air outlet chamber (42a); an activated carbon inner chamber (40a) formed between the inner tube (42) and the outer tube (41) and into which activated carbon is inserted; and an air outlet chamber (42a) formed by the inner circumferential surface of the inner tube (42) and forming a path through which air passing through the activated carbon inner chamber (40a) is sucked in by the suction force of the driving fan (20).

According to an embodiment of the present invention, in a recycling type volatile organic compound dust collection and purification device, the horizontal width (W1) of the activated carbon chamber (40a) is 12 to 14.5 cm, the air flow velocity (V1) across the activated carbon chamber (40a) is 30 to 50 cm/sec, and the time for air to pass through the activated carbon chamber (40a) is at least 0.3 to 0.5 seconds. As a result of testing, it was found that this exhibits excellent performance in terms of the activated carbon capture effect and the amount of air purified per unit time. In an embodiment of the present invention, the horizontal width (W1) of the activated carbon chamber (40a) is 13.2 cm.

If the horizontal width (W1) of the activated carbon chamber (40a) is too small, the time required to pass through the activated carbon chamber (40a) is too short, resulting in a small amount of hazardous substances captured. If the horizontal width (W1) of the activated carbon chamber (40a) is too large, the device becomes large and the amount of activated carbon input becomes excessively large, resulting in a disadvantage.

When the effective air flow velocity (V1: vector quantity) across the activated carbon chamber (40a) is less than 30 cm/sec, the amount of air purified per unit time becomes small, and when it is greater than 50 cm/sec, the amount of harmful substances captured becomes small. Therefore, it was found that 30 to 50 cm/sec is desirable.

<Activated carbon purification unit, inner tube lower structure>

As illustrated in FIG. 5b, in an activated carbon purification unit (40) according to one embodiment of the present invention, a longitudinal blocking plate (42-2) formed to have a first height (H1) while blocking an air passage hole (42-1) at a lower long edge portion of an inner tube (42), a transverse blocking plate (42-3) formed to have a first height (H1) while blocking an air passage hole (42-1) at a lower short edge portion of an inner tube (42), and a bottom plate (42-5) that closes the lower bottom of the inner tube (42) are provided.

Accordingly, the length of the activated carbon inner chamber (40a) through which the air that has entered through the air passage hole (41-3) formed at the bottom of the outer tube (41) flows before being discharged to the air discharge chamber (42a) of the inner tube (42) is made greater than the first height (H1), so that the air that has entered through the air passage hole (41-3) formed at the bottom of the outer tube (41) is discharged to the air discharge chamber (42a) after undergoing the essential capturing action by the activated carbon.

As illustrated in Fig. 5b, the first height (H1) is 12 to 14.5 cm, preferably 13.2 cm. In this case, air introduced into the air passage hole (41-3) formed at the bottom of the outer tube (41) is discharged to the air outlet chamber (42a) after undergoing the essential capturing action by the activated carbon.

Pocket filter section

As illustrated in FIG. 6(a, b, c, d), in a volatile organic compound dust collection and purification device of a recycling type according to an embodiment of the present invention, a pocket filter unit (30) is inserted into a pocket filter unit space (R1) formed at the lower portion of a body frame (10), and is configured to include a sliding filter plate (31) having a plurality of first air inlet holes (31a); a pocket-shaped pocket filter (32) that covers the upper portion of the first air inlet hole (31a) of the filter plate (31) and has an open lower portion; a detachable fixing member (33) that fixes the lower portion of the pocket filter (32) around the first air inlet hole (31a) of the filter plate (31); a pocket filter unit door (34) that opens and closes the front of the pocket filter unit space (R1); and a door opening/closing member (35) that opens and closes the pocket filter unit door (34). A drawer-type dust collector may be further provided at the bottom of the pocket filter unit (30) to collect and discard dust that falls under the filter plate (31).

As shown in Fig. 6c, in the pocket filter unit (30), the detachable fixing member (33) is configured to include a first air inlet hole (31a) formed in the center, an outer protruding ring piece (33-1) formed to protrude upwardly on the outer periphery, an inner protruding ring piece (33-3) formed to protrude upwardly at the edge of the first air inlet hole (31a), a connecting horizontal part (33-2) connecting the outer protruding ring (33-1) and the inner protruding ring (33-3), and a plurality of fixing piece insertion grooves (33-4) formed on the inner protruding ring piece (33-3) and into which the fixing piece (31-2) of the filter plate (31) is inserted.

As shown in FIG. 6c and FIG. 6d, in the pocket filter part (30), the inner protruding ring piece (33-3) formed to protrude upward at the edge of the first air inlet hole (31a) has a shape in which the height increases from the protruding bottom part (33-3a) formed on one side of one fixed piece insertion groove (33-4) to the protruding high part (33-3b) formed on the other side of the other fixed piece insertion groove (33-4).

<Activated carbon inlet/outlet cover plate>

As illustrated in FIG. 7(a, b), a volatile organic compound dust collection and purification device of a recycling type according to an embodiment of the present invention further comprises a chamber cover plate (44) that detachably covers the upper portion of an activated carbon chamber (40a). The cover plate (44) is closed when collecting hazardous substances, and opens to form an activated carbon outlet when the activated carbon is taken out for activated carbon regeneration, and serves as an inlet when the activated carbon is initially introduced or reintroduced.

As shown in Fig. 7(a, b), the outer edge of the inner chamber cover plate (44) is fixed to the first horizontal support piece (41-6) formed on the upper end of the outer tube (41) by a support or fixing means (45), and the inner edge of the inner chamber cover plate (44) is fixed to the second horizontal support piece (42-6) formed on the upper end of the inner tube (42) by a support or fixing means (45) so as to be openable.

Accordingly, the activated carbon dust collector (200) can collect dust by sucking in activated carbon in pellet form through the activated carbon outlet formed by the opening of the cover plate (44).

The facility may be equipped with a glass wool filter for primary purification of harmful gases including VOCs, gases and fine dust.

The activated carbon purification unit (40) of the volatile organic compound adsorption device (100) of this type has a reduced adsorption capacity as the harmful substances adsorbed on the built-in activated carbon become saturated, so the activated carbon of the activated carbon purification unit (40) is extracted using an activated carbon dust collector exchanger (200) to perform regeneration treatment for exchange or recycling.
