Description

TECHNICAL FIELD [0001] The present invention relates to a filter rotary type volatile gas processing apparatus,

The present invention is a treatment apparatus for purifying volatile noxious gas by rotating a filter.

In general, a plant using volatile organic compounds (VOC: Volatile Organic Compounds), more specifically, a volatile gas such as a semiconductor, an LCD, and a paint factory, is equipped with a purifier for purifying the volatile organic compound.

The purifier usually consists of a blower fan and an adsorption filter. Specifically, the blowing fan pressurizes the mixed gas of the VOC mixed with the volatile organic compound toward the adsorption filter, and this adsorption filter is configured to purify the mixed gas by adsorbing the volatile harmful substance from the VOC mixed gas.

Such a purifier suffers from adsorption of a large amount of volatile harmful substances in the adsorption filter, resulting in deterioration of adsorbability. At this time, the efficiency of the purifier can be normalized by replacing the adsorption filter with a new adsorption filter.

Examples of the adsorption filter include a rotary disk filter, a cylinder filter, and a stack filter.

In the rotary disk filter, a plurality of disk filters are sequentially disposed in a drum-shaped housing and rotationally driven to perform adsorption and desorption of volatile harmful substances, so that the filter can be regenerated and reused, but the gas treatment capacity is lowered.

The cylinder filter is composed of a cylindrical housing having a hollow portion. Since the mixed gas flowing toward one end is discharged to the peripheral surface, the gas processing capacity is high, but the cost is high and installation and replacement are difficult.

Stack filters are stacked to facilitate installation and replacement, but adsorptive capacity can be exhausted prematurely by fixed adsorption activity on only one side.

Therefore, when the above-described filter is applied in implementing the purifier, it is possible to individually incur relative problems. In particular, in the case of a rotary disk filter, since it is possible to regenerate the filter, productivity is improved in terms of long-term equipment operation. However, the rotary disk filter is more likely to be applied to other filters.

An object of the present invention is to provide a filter rotation type volatile gas processing device capable of improving the regeneration efficiency through a simple rotation type structure and purifying a large amount of volatile gas.

The filter unit may further include a filter housing coupled to the first filter unit and the second filter unit, the filter housing being configured to block between the inlet and the outlet.

Here, the filter housing may include: a first partition wall having an opening in the direction of the inlet; A second partition formed between the first partition and the outflow portion to prevent the untreated gas flowing through the opening from moving to the outflow portion; A first sidewall connecting the first sidewall and the second sidewall and having the first filter unit coupled thereto; And a second sidewall disposed to be symmetrical with the second sidewall and coupled with the second filter unit.

The filter guide portion 127 may be formed of a mesh having a plurality of wires intersecting with each other, and thin iron or glass fiber may be used as the material.

The shaft 130 is a shaft for rotating the first filter unit 121 and the second filter unit 123 and is disposed in the shaft hole 125 of the first filter unit 121 and the second filter unit 123, Can be combined. One end and the other end of the shaft 130 may be connected to a rotation driving part 131 installed on one side or both sides of the housing 110 as shown in FIG. Therefore, the first filter unit 121 and the second filter unit 123 can be rotated in the same direction according to the driving force of the shaft 130. [ In the present embodiment, the shafts 130 are configured as a single unit to simultaneously rotate the first filter unit 121 and the second filter unit 123, but the present invention is not limited thereto, The filter unit 120 may be constituted by a plurality of units corresponding to the filter unit 120 and may be operated individually.

The suction unit 140 includes volatile harmful substances adsorbed on the respective surfaces of the first filter unit 121 and the first filter unit 121 which are fixedly installed between the first filter unit 121 and the second filter unit 121 Inhale. The suction unit 140 may include a first suction unit 141 and a second suction unit 143.

The first suction unit 141 is arranged such that the opening side thereof faces the first filter unit 121 in the adsorption space A1 and sucks volatile harmful substances adsorbed to the first filter unit 121. [

The second suction unit 143 is arranged so that its opening side faces the second filter unit 123 so as to be symmetrical with the first suction unit 141 in the suction space A1 and is attracted to the second filter unit 123 Inhalation of volatile harmful substances.

Although the suction unit 140 is not shown in the present embodiment, it can be fixed to the bottom surface of the adsorption space A1 by the fixing means. In this embodiment, the first suction unit 141 and the second suction unit 143 are constituted by the individual suction units 140 separated from each other, but the present invention is not limited thereto. In other words, the first suction unit 141 and the second suction unit 143 may be formed in a single structure in which each opening is formed on the opposite surface.

4, the suction unit 140 is formed in a fan shape in which a vertex is positioned in the shaft hole 125 of the filter unit 120, so that when the circular filter unit 120 is rotated, The substance can be inhaled.

The suction unit 140 communicates with the discharge part 115 through the discharge tube 117 described above so that the volatile harmful substance sucked through the suction unit 140 can be discharged to the discharge part 115.

The injection unit 150 is installed on the opposite side of the filter unit 120 in which the suction unit 140 is installed and injects the heating gas into the filter unit 120. The injection unit 150 may include a first injection unit 151 and a second injection unit 153.

The first injection unit 151 is fixedly arranged with respect to the first filter unit 121 so as to be symmetrical with the first suction unit 141 and injects the heating gas toward the first filter unit 121. Specifically, the first injection unit 151 is disposed in the first discharge space A2, which is the space between the first filter unit 121 and the housing 110, so that the opening is directed toward the first filter unit 121 do. A heating gas supply unit formed at one side of the housing 110 is connected to a supply pipe 157, and the heating gas is supplied to the first filter unit 121 to inject the heating gas.

The second injection unit 153 is fixedly disposed to the second filter unit 123 so as to be symmetrical with the second suction unit 143 and injects the heating gas toward the second filter unit 123. In other words, the second injection unit 153 is formed in the same structure as the first injection unit 151 and installed in the second discharge space A3, which is a space between the second filter unit 123 and the housing 110 And the heating gas is injected into the second filter unit 123. At this time, the second injection unit 153 is also supplied with the heating gas through the heating gas supplying unit. In this embodiment, a plurality of heating gas supply units are provided at different positions, but the present invention is not limited thereto. That is, a single heating gas supply unit may be provided to simultaneously supply the heating gas to the first injection unit 151 and the second injection unit 153.

The filter housing 160 is coupled with the filter unit 120 between the inlet 111 and the outlet 113 to switch the direction of movement of the untreated gas G1 towards the filter unit 120. The filter housing 160 may include a first partition 161, a second partition 163, a first sidewall 165, and a second sidewall 167.

As shown in FIG. 2, the first partition 161 is provided to block the cross-sectional area between the inlet 111 and the outlet 113, and an opening 161a is formed in the center axis thereof. Therefore, the untreated gas G1 flowing in the inflow section 111 can be moved toward the outflow section 113 only through the opening section 161a.

The second partition wall 163 is provided between the first partition 161 and the outlet 113 to prevent the untreated gas G1 flowing through the opening 161a from moving to the outlet 113. [ In other words, the second partition 163 is formed to correspond to the opening 161a, and both side ends thereof are disposed so as to be spaced apart from the housing 110.

The first sidewall 165 connects one side of the first barrier rib 161 and one side of the second barrier rib 163 so as to be in parallel with the movement direction of the untreated gas G1 and the first filter unit 121 is coupled do. Specifically, the second sidewall 167 connects one region of the first barrier rib 161 on the opening 161a side and one end of the second barrier rib 163 in parallel to the movement direction of the untreated gas G1. The first sidewall 165 may be coupled with the first filter unit 121 through the receiving hole 168 through a receiving hole 168 corresponding to the first filter unit 121. When the first filter unit 121 is coupled to the receiving hole 168, since the space between the adsorption space A1 and the first discharge space A2 is interrupted, the untreated gas G1 passes through the first filter unit 121 And can be moved to the first discharge space A2.

The second sidewall 167 is disposed to be symmetrical with the first sidewall 165 and coupled with the second filter unit 123. In other words, the second sidewall 167 is formed to have the same structure as the first sidewall 165, and the second sidewall 165 is formed in a region of the first sidewall 161 where the first sidewall 165 is not coupled, 163). Further, it can be coupled with the second filter unit 123 through the receiving hole 168 formed to pass through one surface and the other surface.

According to the combination of the filter housing 160 and the filter unit 120, the opening 161a is formed on the inlet 111 side and the remaining portion is surrounded by the filter unit 120 and the second partition 163 An adsorption space A1 to be surrounded is formed. Therefore, the untreated gas G1 can be moved to the outlet 113 only through the filter unit 120 by being blocked by the second partition 163.

The sealing portion 170 can prevent the untreated gas G1 from being washed out through the joint portion between the filter housing 160 and the filter unit 120. The sealing portion 170 will be described in detail later with reference to FIG. 5 and FIG.

The sealing portion 190 is formed to extend in the direction of the filter unit 120 along the opening edge of the injection unit 150 and the suction unit 140 as shown in FIG. The injection unit 150 and the suction unit 140 are spaced apart from the filter unit 120 by a predetermined distance but each of the sealing parts 190 is extended to be in contact with the filter guide unit 127 of the filter unit 120. Thus, the internal space of the injection unit 150 and the suction unit 140 forms a closed space in contact with the filter unit 120. Therefore, the region where the injection unit 150 injects the heating gas and the suction region of the suction unit 140 can be divided into the closed region separated from the other region, so that the adsorption capability for the specific region can be further improved.

An operation method of the same configuration of the apparatus 100 for treating the volatile gas is as follows.

First, an untreated gas G1 containing a volatile harmful substance flows through the inflow section 111. The untreated gas G1 is moved toward the outlet 113 by the injection pressure. Since the first partition 161 interrupts the space between the inlet 111 and the outlet 113, the untreated gas G1 flows into the adsorption space A1 through the opening 161a of the first partition 161 ≪ / RTI >

The untreated gas G1 flowing into the adsorption space A1 is blocked by the second partition wall 163 from moving to the outflow portion 113 and branched in the direction of both sides of the second partition wall 163. On both sides of the second bank 163, the first filter unit 121 and the second filter unit 123 which are symmetrical to each other are arranged so as to be parallel to each other and rotated. Thus, the branched untreated gas G1 passes through the first filter unit 121 and the second filter unit 123 and is moved to the outlet 113. [ At this time, the volatile harmful substances included in the untreated gas G1 are adsorbed by the adsorbing component of the filter unit 120 such as zeolite in the passage of the filter unit 120. Therefore, the processing gas G2 from which volatile harmful substances have been removed from the untreated gas G1 can be moved to the outlet 113 side.

When the volatile harmful substances are continuously deposited on the filter unit 120, the adsorption capacity is lowered, and therefore, the regeneration of the filter unit 120 is required. To this end, the first injection unit 151 and the second injection unit 153, which are fixedly arranged toward the filter unit 120 in the first and second discharge spaces A2 and A3, respectively, 1 filter unit 121 and the second filter unit 123, respectively. At this time, since the first suction unit 141 and the second suction unit 143 are disposed in the adsorption space A1 so as to correspond to the first injection unit 151 and the second injection unit 153, Volatile and harmful substances that are detached from the filter unit 120 are sucked into the suction unit 140 and discharged to the external device.

The injection unit 150 and the suction unit 140 are fixedly mounted and the filter unit 120 is rotated in accordance with the driving of the shaft 130 so that the injection unit 150 and the suction unit 140 face each other The adsorption region is changed every time the filter unit 120 rotates. Particularly, since the injection unit 150 and the suction unit 140 are formed in the same fan shape, the entire area of the circular filter unit 120 can be desorbed.

Here, the filter unit 120 and the filter housing 160 of this embodiment are disposed so as to be perpendicular to the bottom surface of the housing 110. However, the present invention is not limited thereto, and the filter unit 120 and the filter housing 160 may be disposed parallel to the bottom surface of the housing 110. Specifically, the filter unit 120 may be arranged such that each surface in the adsorption space A1 is parallel to the bottom surface. In other words, the first filter unit 121 and the second filter unit 123 can be placed in the adsorption space in such a manner that they are stacked and separated from each other. The filter housing 160 coupled with the filter unit 120 may also be arranged in the same structure. According to this structure, the first filter unit 121 is spaced apart from the bottom surface of the housing 110 in parallel. Further, the second filter unit 123 is spaced apart from the ceiling portion of the housing 110 in a spaced-apart relationship. Thus, the filter unit 120 and the filter housing 160 may be spaced apart from the bottom surface and the ceiling within the housing 110. At this time, the first sidewall 165 and the second sidewall 167 can be coupled to each other with additional partition walls so that the direction toward the side of the housing 160 can be closed. According to the filter unit of this embodiment, Since the respective surfaces of the unit 121 and the second filter unit 123 are arranged to face the bottom surface and the ceiling portion of the housing 110, the untreated gas G1 flowing into the suction space A1 flows toward both sides of the existing housing 110 To the floor surface and to the ceiling portion.

The configuration and operation method of the volatile gas processing apparatus 100 have been described above. 5 and 6, the closure 170 of the volatile gas processing apparatus 100 of the present embodiment will be described in more detail.

FIGS. 5 to 6 are views for explaining the structure of the filter unit (FIGS. 1 and 120) and the sealing unit 170 according to an embodiment of the present invention. The sealing portion 170 is formed in the same structure as the first filter unit 121 and the second filter unit 123 so that the first side wall 165, the first filter unit 121, The sealing unit 170 will be described with respect to the one suction unit 141.

As shown, the volatile gas processing apparatus 100 includes a sealing portion 170 for closing a clearance area GA, which is an area between the first filter unit 121 and the first side wall 165.

As the first filter unit 121 is rotatably coupled to the first sidewall 165, a gap area GA may exist between the first filter unit 121 and the first filter unit 121, and the untreated gas G1 may not be purified through the corresponding gap area So that it can be prevented through the hermetically sealed part 170.

The sealing portion 170 may be formed to extend along the rim of the receiving hole 168 of the first filter unit 121 facing the first suction unit 141 by a predetermined length toward the central shaft hole 125 . At this time, the material of the sealing portion 170 may be made of an elastic material such as rubber or resin. Therefore, the sealing portion 170 can cover the clearance area GA when the first filter unit 121 is coupled to the receiving hole 168 as shown in FIG.

When the untreated gas G1 is moved to the first filter unit 121 due to the elastic material of the sealing unit 170, the sealing unit 170 is moved to the first filter unit 121 . When the sealing portion 170 is in close contact with the first filter unit 121, it is possible to prevent the untreated gas G1 from flowing out through the gap region GA as it is completely covered.

The first sidewall 165 may include a roller 169 to facilitate the rotation of the first filter unit 121.

The roller 169 is provided along the inner surface of the receiving hole 168 facing the first filter unit 121 and can be rotated when it contacts the first filter unit 121. At this time, the rollers 169 may be constituted of a plurality of rollers 169 and may contact the first filter unit 121 in different directions of the receiving holes 168. The roller 169 is equally applicable to the first sidewall 165 as well as the second sidewall 167 not shown.

7 is a partial cross-sectional view for explaining a volatile gas processing apparatus 200 having a circulation unit 260 according to another embodiment of the present invention.

As shown, the volatile gas processing apparatus 200 is substantially the same as the volatile gas processing apparatus of FIGS. 1 to 6 (FIGS. 1 and 100) but differs in that a circulation unit 260 is added.

The circulation unit 260 collects the processing gas G2 passing through the filter unit 220 and supplies it to the injection unit 250. [ The circulation unit 260 may include a first circulation unit 261 and a second circulation unit 263.

The first circulation unit 261 is connected to the first injection unit 251 and supplies the process gas G2 passing through the first filter unit 221 to the first injection unit 251. [ Specifically, the first circulation unit 261 is disposed continuously to the first injection unit 251, and communicated through the circulation tube 265. At this time, the first circulation unit 261 may be coupled to the inside of the housing or the first injection unit 251 by a coupling means not shown. At this time, the first filter unit 221 can be rotated so that the region detached by the first injection unit 251 can be moved toward the first circulation unit 261. [ In this case, since the area in which the volatile harmful substance is removed by the first injection unit 251 is not completely cooled, the adsorption efficiency of the untreated gas G1 passing through the un-cooled area may be lowered. Accordingly, the first circulation unit 261 collects the process gas G2 passing through the uncooled region, which is desorbed by the first injection unit 251, and supplies it to the first circulation unit 261 again. The first circulation unit 261 heats the process gas G2 supplied through the heating unit 254 provided in the first circulation unit 261 to convert the process gas G2 into the heating gas HG and injects it into the first filter unit 221 .

The second circulation unit 263 is constructed in the same structure as the first circulation unit 261 and is continuously disposed in the second injection unit 253 to collect the process gas G2 passing through the second filter unit 223 And supplies it to the second injection unit 253. Hereinafter, the operation method of the second circulation unit 263 is the same as that of the first circulation unit 261, and therefore, it is omitted.

Here, though not shown, the circulation unit 260 may include therein a circulation fan for moving the processing gas G2 to be collected to the injection unit 250.

According to such a circulation unit 260, a separate apparatus or design for generating the heating gas HG is not required, productivity can be further improved, and the processing efficiency of the untreated gas G1 passing through the non- .

The filter rotary type volatile gas processing apparatus as described above is not limited to the configuration and the operation manner of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
