Description

TECHNICAL FIELD [0001] The present invention relates to a catalyst coating method and a catalyst coating apparatus,

The present invention relates to a coating apparatus for a catalyst for purification of exhaust gas and a method for coating a catalyst on a carrier, and more particularly, to a method for uniformly and rapidly coating a catalyst slurry on a carrier and a coating apparatus for carrying out the same.

Coating the catalyst with a carrier having a specific shape is used for purifying the exhaust gas generated from the vehicle or for treating the polluted gas. For example, a carrier coated with a catalyst may be used in an exhaust pipe of a vehicle, and may be used to remove various pollutants generated in a device manufacturing process such as a semiconductor.

In recent years, demands for treatment of gases such as sulfides, nitrides, and fluorides generated in a semiconductor manufacturing process have increased as environmental demands have arisen. Particularly, various processes such as etching and deposition are used in the semiconductor manufacturing process, and various kinds of noxious gases are generated through the process equipment and the like. The generated noxious gas may be removed by wet, dry, or the like, and may be removed through a burning process.

Even if the harmful gas is treated by using the various processing techniques described above, the remaining harmful components and the like are still processed. Therefore, a treatment system using a catalyst or the like is applied, and a system in which a carrier is coated with a certain kind of catalyst is included in the noxious gas treatment equipment.

In the case of a carrier coated with a catalyst, various shapes are obtained, and the type of the gas to be treated varies depending on the shape and the catalyst to be coated. Normally, the carrier has a honeycomb structure. The inner wall of the carrier having a honeycomb structure should be coated with a certain thickness and concentration as a catalyst. Upon coating the catalyst on the carrier, the coated catalyst should be coated to a uniform concentration and thickness.

Various techniques are developed for uniform coating of the catalyst. For example, Japanese Laid-Open Patent Application No. 2009-189983 discloses a technique in which a catalyst slurry is regularly coated at the time of coating and a predetermined amount is coated in the carrier.

According to the disclosed Japanese Laid-Open Patent Application, a carrier in the form of a honeycomb is provided close to the liquid surface of the slurry containing the catalyst material. Subsequently, when a suction force is applied at the top of the carrier, the slurry moves upward from the bottom of the carrier. The movement of the slurry to the top is carried out up to a certain height by a constant suction force. Subsequently, the carrier on which the slurry is sucked is inverted upside down. Therefore, the slurry is applied to the upper portion of the inverted carrier, and when the blowing is performed by the air pressure from the upper portion, the slurry is moved downward. Through the above-described process, the catalytic material is applied to the entire interior of the carrier.

In the above-mentioned Japanese Laid-Open Patent Application, when the lower slurry is sucked, almost all of the slurry is sucked. Further, the rotation of the carrier necessarily occurs. Since most of the lower slurry is inhaled, the slurry must be filled each time the carrier is coated. Further, as the carrier rotates, the slurry leaks due to the holding of the carrier in the rotating state. Therefore, it is troublesome that the slurry must be filled in every unit process, and leakage of the slurry is inevitable.

A first object of the present invention is to provide a catalyst coating method capable of minimizing the leakage of slurry and efficiently coating the carrier.

A second object of the present invention is to provide a catalyst coating apparatus for efficiently coating a catalyst.

According to an aspect of the present invention, there is provided a method of manufacturing a semiconductor device, comprising: disposing a first carrier between a first container disposed on an upper portion and a second container disposed on a lower portion; And coating the first slurry with a catalyst slurry stored in the second slurry by rotating the first slurry, the second slurry and the first slurry, and storing the slurry in the first slurry A catalyst coating method is provided.

According to a second aspect of the present invention, there is provided a catalyst coating apparatus comprising: a catalyst coating unit coating a catalyst slurry on a carrier; A transporting and rotating means for rotating the catalyst coating portion or for detaching the carrier; A slurry collection and supply unit for supplying or recovering the catalyst slurry to the catalyst coating unit; And a pressure control unit for applying a vacuum or an air pressure to the catalyst coating unit.

According to the present invention described above, two containers for storing the catalyst slurry or supplying the carrier to the carrier are rotated together with the carrier. Therefore, the outflow of the catalyst slurry generated during the rotation operation of the carrier only is prevented. In addition, it is possible to secure a uniform coating concentration on the carrier by rotating with the containers rather than only the carrier.

Also, among the vessels, a pipe may be optionally provided in the vessel to perform the supply and recovery of the catalyst slurry. However, according to the embodiment, only the supply of the catalyst slurry to one container may be performed, and only the recovery of the catalyst slurry may be performed to the other container.

Therefore, the catalyst coating method and apparatus of the present invention can increase the efficiency of catalyst coating on the carrier, ensure a uniform coating concentration with minimum operation, and increase the recovery rate of the remaining catalyst slurry have.

The catalyst slurry stored in the second vessel 120 through rotation flows through the first carrier 130 and is stored in the first vessel 110. The catalyst slurry stored in the second container 120 may be stored in the first container 110 by the pressure applied from the second container 120 or may be stored in the second container 120 by the suction force applied from the first container 110 ). ≪ / RTI >

Since the second opening and closing means 122 has a ring shape, the catalyst slurry is introduced into the first carrier 130 through the open region which is an empty space inside the second opening and closing means 122. Therefore, the inner diameter of the second opening and closing means 122 having the ring shape is the same as the diameter of the first carrier 130. Of course, according to the embodiment, the inner diameter of the second opening and closing means 122 may be slightly smaller or larger than the diameter of the first carrier 130. [ This may vary depending on the aspect of the first carrier 130 having a honeycomb structure.

Whereby the first carrier 130 is coated with the catalyst slurry.

Further, after the second container 120 is coated with the first carrier 130 and stored in the first container 110, further blowing from the second container 120 toward the first container 110 may be performed have.

During the movement and blowing of the catalyst slurry, the second opening and closing means 122 of the second container 120 serves as a guide for the catalyst slurry to move to the first carrier 130. The pressure for inducing the movement of the catalyst slurry is exerted on the first carrier 130 through the second opening / closing means 122.

Referring to FIG. 3, the first carrier 130 is separated from the first holding means 111 and the second holding means 121. The separated first carrier 130 moves to another stage such as a catalyst slurry drying step.

Referring to FIG. 4, a second carrier 140 having the same shape as the first carrier 130 is held. The second container 120 is disposed on the upper portion of the gripped second carrier 140 and the first container 110 is disposed below the second carrier 140. The catalyst slurry according to the process of FIG. 2 is stored in the first vessel 110.

Then, the first container 110, the second container 120, and the second carrier 140 are rotated. The rotation is 180 degrees. Accordingly, the first container 110 is disposed at the upper portion, and the second container 120 is disposed at the lower portion. Then, the processes of FIGS. 1 and 2 are repeated. Whereby a coating of a new carrier is carried out.

In the above-described embodiment, two containers in addition to the carrier are rotated together with the carrier. Therefore, leakage of the catalyst slurry due to rotation of the carrier does not occur, and the catalyst can be uniformly coated inside the carrier of the honeycomb structure.

Second Embodiment

5 to 7 are cross-sectional views illustrating a method of coating a catalyst slurry according to a second embodiment of the present invention.

Referring to FIG. 5, a first container 210, a second container 220, and a first carrier 230 are disclosed.

The catalyst slurry is not stored in the first vessel 210. Also, a first holding means 211 is provided at the lower end of the first container 210. The first gripping means 211 grips the first carrier 230 coupled to the first container 210. In addition, a first opening and closing means 212 is provided in the first container 210. The first opening and closing means 212 has substantially the same diameter as the first container 210 and has the form of a ring. In addition, the first opening and closing means 212 is immersed in the bottom surface of the first container 210 by gravity.

In addition, the second container 220 holds the first carrier 230 together with the first container 210. The catalyst slurry is stored in the second vessel 220. The grasping of the first carrier 230 is achieved through the second grasping means 221 provided in the second vessel 220. In addition, the second opening / closing means 222 is provided in the second container 220. The second opening and closing means 222 has the same shape as the first opening and closing means 212. However, the second opening and closing means 222 is immersed in the lower part of the second container 220 due to gravity.

Referring to FIG. 6, the first container 210, the second container 220, and the first carrier 230 are rotated by 180 degrees. The catalyst slurry stored in the second vessel 220 through the rotation flows through the first carrier 230 and is stored in the first vessel 210. The catalyst slurry stored in the second container 220 may be stored in the first container 210 by the pressure applied from the second container 220 or may be stored in the first container 210 by the suction force applied from the first container 210. [ ). ≪ / RTI >

Since the second opening and closing means 222 has the shape of a ring, the catalyst slurry is introduced into the first carrier 230 through the open region which is an empty space inside the second opening and closing means 222. Therefore, the inner diameter of the second opening and closing means 222 having the ring shape is the same as the diameter of the first carrier 230. Of course, according to the embodiment, the inner diameter of the second opening and closing means 222 may be slightly smaller or larger than the diameter of the first carrier 230. Which may vary depending on the aspect of the first carrier 230 having a honeycomb structure.

The first carrier 230 is coated with the catalyst slurry.

Further, after the second container 220 is coated with the first carrier 230 and stored in the first container 210, further blowing from the second container 220 toward the first container 210 can be performed have. The catalyst slurry coated on the inner wall of the first carrier 230 through the blowing is more uniformly coated. Further, the catalyst slurry discharged through blowing is stored in the first vessel 210.

6, the second opening and closing means 222 moves to the lower side of the second container 220 by gravity, and the first opening and closing means 212 is moved to the lower side of the first container 210.

During the movement and blowing of the catalyst slurry, the second opening and closing means 222 of the second container 220 serves as a guide for the catalyst slurry to move to the first carrier 230. In addition, the pressure for inducing the movement of the catalyst slurry is exerted on the first carrier 230 through the second opening / closing means 222.

Referring to FIG. 7, the entire first container 210, the second container 220, and the first carrier 230 are rotated 180 degrees again. The first container 210 is disposed above the first carrier 230 through rotation and the second container 220 is disposed below the first carrier 230. The first opening and closing means 212 disposed on the bottom surface of the first container 210 due to gravity is disposed in a region where the first container 210 and the first carrier 230 are adjacent to each other. Further, the second opening / closing means 222 disposed in the second container 220 is disposed on the bottom surface of the second container 220 through rotation and gravity.

Subsequently, a secondary coating is performed from the first container 210 to the first carrier 230. [ The secondary coating is the same process as the primary coating disclosed in Fig. That is, the catalyst slurry passes through the interior of the first opening / closing means 212 disposed on the bottom surface of the first container 210 and flows to the first carrier 230. The catalyst slurry flowing through the first carrier 230 performs a secondary coating on the first carrier 230 and is stored in the lower second container 220.

In the second embodiment described above, a two-step coating is performed on one carrier. That is, a two-step coating is carried out through rotation of the containers and the carrier. In the process of FIG. 6, which is a primary coating process, the upper portion of the first carrier adjacent to the first container through the blowing or the like may have a thinner coating thickness than the lower portion. This has the advantage that it can be compensated in the secondary coating through rotation.

Third Embodiment

8 is a conceptual view showing a catalyst coating apparatus according to a third embodiment of the present invention.

Referring to FIG. 8, the catalyst coating apparatus of this embodiment includes a transfer and rotation unit 300, a slurry collection and supply unit 400, a pressure control unit 500, and a catalyst coating unit 600.

The transporting and rotating means 300 performs the rotation of the catalyst coating portion 600. Also, the carrier 630 of the catalyst coating part 600 is transported. The catalyst coating part 600 may be rotated 180 degrees in one coating and rotated 180 degrees in the other direction in sequential rotation.

Through the rotation of the catalyst coating portion 600, the coating operation of the catalyst slurry disclosed in the first and second embodiments is performed. Further, when the coating of the catalyst slurry is completed, the carrier 630 is released from the catalyst coating portion 630 through the transporting and rotating means.

The slurry collection and supply unit 400 has a slurry reservoir 410, a slurry supply pump 420, and a slurry collection pump 430.

The slurry reservoir 410 stores the catalyst slurry supplied from the outside or recovered from the catalyst coating portion 600, and is maintained to maintain a constant and uniform catalyst concentration through the agitator. The catalyst slurry is supplied from the slurry reservoir 410 to the catalyst coating portion 600 and the catalyst slurry is recovered from the catalyst coating portion 600 into the slurry reservoir 410.

The slurry supply pump 420 is connected between the slurry reservoir 410 and the catalyst coating unit 600. The slurry supply pump 420 connected between the slurry reservoir 410 and the catalyst coating portion 600 through the slurry supply pipe 422 supplies the catalyst slurry to the catalyst coating portion 600. Particularly, the slurry supply pipe 422 between the slurry supply pump 420 and the catalyst coating portion 600 is provided with a supply valve 421. Therefore, when the supply valve 421 is opened, the slurry supply pump 420 can supply the catalyst slurry to the catalyst coating portion 600.

The catalyst slurry coated in the catalyst coating part 600 is transferred to the slurry reservoir 410 through the slurry recovery pump 430. A recovery valve 431 may be provided in the slurry recovery pipe 432 between the slurry recovery pump 430 and the catalyst coating unit 600. Accordingly, when the recovery operation of the slurry occurs, the recovery valve 430 is opened and the catalyst slurry of the catalyst coating portion 600 is recovered to the slurry reservoir 410 through the slurry recovery pump 430.

The slurry supply pipe 422 between the slurry supply pump 420 and the catalyst coating unit 600 and the slurry recovery pipe 432 between the slurry recovery pump 430 and the catalyst coating unit 600 are made of a flexible material . This is to ensure smooth supply and discharge of the catalyst slurry even in the rotational motion of the catalyst coating part 600.

The pressure control unit 500 is connected to the catalyst coating unit 600. The pressure control unit 500 has a vacuum pump 510, vacuum valves 520 and 540, and air pressure valves 530 and 550. Through the operation of the pressure control unit 500, the catalyst slurry of the catalyst coating unit 600 is coated with the carrier 630.

When the first vacuum valve 520 is opened and the first atmospheric valve 530 is closed, the vacuum pump brings the first container 610 connected thereto to a vacuum state. In addition, when the first vacuum valve 520 is closed and the first atmospheric pressure valve 530 is opened, atmospheric pressure is supplied to the first container 610 connected thereto. In particular, the first and second pressure pipes 560 and 560, which are pipes between the air pressure valves 530 and 550 and the catalyst coating part 600 and between the vacuum valves 520 and 540 and the catalyst coating part 600, The pressure pipe 570 is preferably made of a flexible material. This is because it is easy to form a vacuum or an air pressure in the catalyst coating portion 600 during the rotation operation of the catalyst coating portion 600.

The catalyst coating unit 600 performs the operations described in the first and second embodiments. The catalyst coating portion 600 has a first container 610 and a second container 620, and has respective gripping means in contact with the respective containers. The carrier 630 is connected to the first container 610 and the second container 620 through the gripping means. As described above, the first opening and closing means and the second opening and closing means may be additionally provided in the first container 610 and the second container 620. The configuration of the catalyst coating portion 600 is the same as that described in the first embodiment and the second embodiment.

When the first vacuum valve 520 is closed while the catalyst slurry is stored in the first container 610 and atmospheric pressure is supplied to the first container 610 when the first air pressure valve 530 is opened. Further, the second vacuum valve 540 is opened in the second container 620, and the second atmospheric pressure valve 550 is closed. Accordingly, the pressure from the first vessel 610 toward the second vessel 620 acts, and the catalyst slurry in the first vessel 610 moves to the second vessel 630 through the carrier 630.

According to the embodiment, by opening the first and second atmospheric pressure valves 530 and 550 and closing the first and second vacuum valves 520 and 540, (610) to the second container (620). This is due to the movement of the catalyst slurry due to gravity. Thereafter, the carrier 630 can be blown through the opening of the second vacuum valve 540 and the closing of the second atmospheric pressure valve 550.

Subsequently, the catalyst-coated carrier 630 is removed through the transfer and rotation means 300, and a new carrier is seated between the first container 610 and the second container 620.

The new carrier, which is seated between the first vessel 610 and the second vessel 620, is rotated by the conveying and rotating means 300. Further, the first container 610 and the second container 620 are rotated simultaneously with the rotation of the carrier. Accordingly, the second container 620 is provided on the upper portion of the new carrier, and the first container 610 is provided on the lower portion. The supply of the catalyst slurry to the new carrier is achieved by the opening and closing operations of the air pressure valves 530, 550 and the vacuum valves 520, 540. This is accomplished by supplying atmospheric pressure to the second container 620 disposed at the top and supplying atmospheric pressure to the first container 610 at the bottom. Also, the supply of atmospheric pressure to the upper second container 620 and the supply of vacuum to the lower first container 610 are also achieved.

The supply and recovery of the catalyst slurry is accomplished through a slurry recovery line 432 connected to at least one of the vessels. 8, the catalyst slurry may be supplied to the second vessel 620 via the slurry supply line 422, and the catalyst slurry may be supplied to the second vessel 620 through the slurry recovery line 432, To the storage tank.

In the embodiments of the present invention described above, two containers for storing the catalyst slurry or supplying the carrier slurry are rotated together with the carrier. Therefore, the outflow of the catalyst slurry generated during the rotation operation of the carrier only is prevented. In addition, it is possible to secure a uniform coating concentration on the carrier by rotating with the containers rather than only the carrier.

Also, among the vessels, a pipe may be optionally provided in the vessel to perform the supply and recovery of the catalyst slurry. However, according to the embodiment, only the supply of the catalyst slurry to one container may be performed, and only the recovery of the catalyst slurry may be performed to the other container.

Therefore, the catalyst coating method and apparatus of the present invention can increase the efficiency of catalyst coating on the carrier, ensure a uniform coating concentration with minimum operation, and increase the recovery rate of the remaining catalyst slurry have.
