Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and in particular to a dry adsorption device. Background Technology

[0002] Traditional dry adsorption units typically employ manual or semi-automatic unloading methods. Once the adsorbent (such as activated carbon or metal oxides) reaches saturation, the adsorption tower must be shut down and residual gas vented. The spent adsorbent is then discharged via gravity or a mechanical screw conveyor and placed in a sealed container to prevent secondary pollution. The waste (spent adsorbent) is then disposed of as hazardous waste by a specialized organization. However, manual or semi-automatic operation exposes the waste to air, potentially posing safety hazards such as poisoning during manual operation. Therefore, there is an urgent need for a dry adsorption unit that minimizes the chance of waste contact with personnel during unloading. Utility Model Content

[0003] To address the aforementioned issues, this application provides a dry adsorption device that reduces the likelihood of personnel coming into contact with harmful filter media, while also minimizing secondary contamination from the harmful filter media.

[0004] An embodiment of this application provides a dry adsorption device comprising a filter media bed, a receiving mechanism, and a bag-in / bag-out unloading unit, wherein...

[0005] The filter media bed includes a discharge pipe and a partition plate. The filter media bed is filled with filter media. The partition plate is slidably installed on the discharge pipe and is electrically connected to the controller.

[0006] The receiving mechanism is detachably connected to the discharge pipe. The receiving mechanism has a deformable component, which is used to change the volume of the receiving mechanism to change the position of the filter material in the receiving mechanism. The isolation plate is used to connect or block the discharge pipe from the receiving mechanism.

[0007] The bag inlet and outlet unloading unit is sleeved outside the receiving mechanism and the discharge pipe, and the isolation plate is also located inside the bag inlet and outlet unloading unit.

[0008] In the above embodiment, when the isolation plate is closed, its radial cross-section completely overlaps with that of the discharge pipe, effectively sealing the discharge pipe and preventing waste from continuing to fall into the receiving mechanism. The isolation plate serves two functions: firstly, it allows waste to enter the receiving mechanism when open; secondly, it isolates the bag-in-bag-out unloading unit from the filter media filling bed when closed, preventing filter media from continuing to fall into the receiving mechanism. The deformable component changes the volume of the receiving mechanism, thereby changing the position of the waste within it. By changing the position of the waste within the receiving mechanism, the closing operation of the receiving mechanism becomes safe and reliable. The bag-in-bag-out unloading unit can specifically be a plastic bag, whose main function is to isolate the contaminated components from the external environment. The contaminated components are the receiving mechanism and the isolation plate. Since the isolation plate is inserted into the discharge pipe, it comes into contact with the waste, and its surface becomes contaminated with dust. If the isolation plate is exposed to the external environment when it slides out of the discharge pipe, it will cause environmental pollution and pose a safety hazard to operators. Therefore, the isolation plate is also installed in the bag-in-bag-out unloading unit, improving the safety of unloading. Furthermore, the bag-in / bag-out unloading unit provides secondary protection, preventing exhaust gases or harmful dust from escaping to the outside during unloading, thus avoiding environmental pollution and threats to personnel safety. The entire unloading and loading process takes place in a closed environment, minimizing contact between waste and outside air and preventing dust from becoming airborne. Personnel do not have direct contact with the waste, reducing safety risks. Moreover, the overall movement of the housing mechanism and the bag-in / bag-out unloading unit minimizes waste exposure to the external environment, reducing secondary pollution.

[0009] In one embodiment, the receiving mechanism includes a discharge bucket, the deformable component is disposed inside the discharge bucket, the deformable component is an air bladder, the air bladder has an air supply pipe, the bottom of the discharge bucket is provided with a through hole, and the air supply pipe passes through the through hole.

[0010] In one embodiment, the airbag is a balloon.

[0011] In one embodiment, the airbag is an accordion-style airbag.

[0012] In one embodiment, the receiving mechanism further includes a first connecting assembly disposed at the opening of the unloading barrel. The first connecting assembly includes a connecting body, a sealing ring, and a buckle. One end of the connecting body is fixedly connected to the discharge pipe, and the other end is detachably connected to the unloading barrel. The sealing ring is disposed between the unloading barrel and the connecting body. The buckle is installed on the edge of the connecting body facing the unloading barrel and is used to fix the connecting body to the unloading barrel.

[0013] In one embodiment, the connector body is provided with a socket, and the socket is detachably provided with a partition for sealing the unloading bucket. The partition can be inserted into the connector body through the socket and cover the unloading bucket.

[0014] In one embodiment, the receiving mechanism further includes a second connecting component, the second connecting component including a flexible sleeve, one end of which is fixedly connected to the unloading barrel, and the other end of which is sleeved on the discharge pipe.

[0015] In one embodiment, the dry adsorption device further includes a base for supporting the unloading barrel.

[0016] In one embodiment, the dry adsorption device further includes a pressure regulating unit, and the gas supply pipe is connected to the pressure regulating unit.

[0017] In one embodiment, the receiving mechanism includes a flexible discharge bag, one end of which is detachably connected to the discharge pipe. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of the application is provided in conjunction with the accompanying drawings and embodiments.

[0027] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more” unless the context clearly indicates otherwise.

[0028] References to “an embodiment” or “a specific embodiment” as used in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. The terms “comprising,” “including,” “having,” and variations thereof mean “including, but not limited to,” unless otherwise specifically emphasized.

[0029] Semiconductor manufacturing plants emit waste gases containing toxic substances such as arsine, phosphine, and fluorides. These harmful gases are typically treated using a two-stage dry adsorption process. Dry adsorption refers to the removal of toxic and harmful gases by adding neutralizing agents or oxidizing agents to powdered or solid carriers instead of water or other liquids as the treatment medium. Alternatively, powdered or solid absorbents can be used. The first-stage dry adsorption unit generally uses a stainless steel filter media tank, which is replaced entirely during waste treatment. This ensures that personnel do not come into contact with the filter media during replacement. The capacity of the first-stage dry adsorption filter media tank is 100 to 200 liters, and replacement is relatively convenient. However, the total capacity of the second-stage dry adsorption unit, installed outdoors, is tens or even hundreds of times larger than that of the first-stage unit. The second-stage dry adsorption unit cannot be replaced entirely; the filter media must be replaced individually. When replacing the filter media, first purge the secondary dry adsorption unit with nitrogen gas, and require operators to remove the waste filter media while wearing personal protective equipment.

[0030] Using a bag-in, bag-out unloading method can reduce waste leakage and is safer for the environment and personnel. However, if the waste collection device is filled too full when using this method, it can cause problems with sealing. If the seal is not tight, some waste may spill or be exposed to the external environment, which can cause harm to the environment and personnel.

[0031] In view of this, embodiments of this application provide a dry adsorption device that improves the reliability of closed operation during unloading, thereby reducing the probability of personnel coming into contact with harmful filter media and reducing the problem of secondary pollution from harmful filter media.

[0032] Figure 1 A structural diagram of a dry adsorption device provided in one embodiment of this application is shown below. Figure 1 As shown, an embodiment of this application provides a dry adsorption device including a filter media bed 1, a receiving mechanism 201, and a bag-in / bag-out unloading unit 2. The filter media bed 1 is filled with filter media 100 and includes a discharge pipe 101 and a separator plate 202. The separator plate 202 is electrically connected to an external controller (not shown) and is slidably mounted on the discharge pipe 101. The receiving mechanism 201 is detachably connected to the discharge pipe 101. Changing the position of the separator plate 202 via the controller connects or disconnects the discharge pipe 101 from the receiving mechanism 201. When replacing the filter media 100, waste material is discharged from the filter media bed 1 through the discharge pipe 101 under gravity. The receiving mechanism 201 has a deformable component 2011, which is used to change the volume of the receiving mechanism 201, thereby changing the position of the filter media 100 within the receiving mechanism 201. The bag inlet and bag outlet unloading unit 2 is installed outside the receiving mechanism 201 and the discharge pipe 101, and the isolation plate 202 is also located inside the bag inlet and bag outlet unloading unit 2.

[0033] Harmful gases enter the filter media bed 1, where the filter media 100 adsorbs them. When the filter media 100 becomes saturated, it becomes waste material, which needs to be discharged from the filter media bed 1 and replaced with new filter media 100. Bag-in / bag-out unloading refers to the "bag-in / bag-out" operating principle used in the filter media processing process, meaning that the replacement or unloading of the filter media is completed in a closed environment to ensure operational safety and reduce dust leakage and environmental pollution.

[0034] In the above embodiment, when the isolation plate 202 is closed, its radial cross-section completely overlaps with that of the discharge pipe 101, effectively blocking the discharge pipe 101 and preventing the waste material 100 from continuing to fall into the receiving mechanism 201. The isolation plate 202 serves two purposes: firstly, when open, it allows the waste material 100 to enter the receiving mechanism 201; secondly, when closed, it isolates the bag-in-bag-out unloading unit from the filter media filling bed 1, preventing the waste material 100 from continuing to fall into the receiving mechanism 201. The deformable component 2011 changes the volume of the receiving mechanism 201, thereby changing the position of the waste material 100 within the receiving mechanism 201. For example, when the volume of the receiving mechanism 201 is small, the waste material is located at the opening of the receiving mechanism 201; when the volume of the receiving mechanism 201 is large, an equal amount of waste material moves downwards under gravity and falls to the bottom of the receiving mechanism 201. The bag-in / bag-out unloading unit 2 can specifically be a plastic bag. Its main function is to isolate contaminated components from the external environment. The contaminated components are the receiving mechanism 201 and the isolation plate 202. Since the isolation plate 202 is inserted into the discharge pipe 101, it comes into contact with the waste material, and its surface will be contaminated with dust. If the isolation plate 202 is exposed to the external environment when it slides out of the discharge pipe 101, it will cause environmental pollution and pose a safety hazard to the operators. Therefore, the isolation plate 202 is also installed in the bag-in / bag-out unloading unit 2 to improve the safety of unloading. In addition, the bag-in / bag-out unloading unit 2 plays a secondary protection role, preventing exhaust gas or harmful dust from escaping to the outside during unloading, thus preventing environmental pollution and threats to personnel safety.

[0035] Because the bag-in-bag-out unloading unit 2 is flexible, operators can perform unloading operations through it. The specific filter media replacement process is as follows: First, the volume of the receiving mechanism 201 is reduced by the deformation component 2011, and then the isolation plate 202 is opened by the controller. The isolation plate 202 slides outward from the discharge pipe 101, thereby connecting the discharge pipe 101 with the receiving mechanism 201. Waste material 100 enters the receiving mechanism 201 from the filter media filling bed 1 under the action of gravity. Due to the small volume of the receiving mechanism 201, waste material 100 is present at the opening of the receiving mechanism 201, which is not conducive to closing the receiving mechanism 201. At this time, the isolation plate 202 is closed by the controller, isolating the filter media filling bed 1 from the receiving mechanism 201. Then, the volume of the receiving mechanism 201 is increased by the deformation component 2011. The waste material 100 in the receiving mechanism 201 moves downward under the action of gravity, falling from the opening of the receiving mechanism 201 to the bottom, thus making the space at the opening of the receiving mechanism 201 larger, which facilitates the sealing operation. After the worker seals the receiving mechanism 201, the receiving mechanism 201 is separated from the discharge pipe 101, and then the bag-in-bag-out unloading unit 2 is separated from the discharge pipe 101 and tied. Finally, the bag-in-bag-out unloading unit 2 and the sealed receiving mechanism 201 are removed as a whole, and the waste material 100 is processed. Then, new filter material 100 is loaded from the top of the filter material filling bed 1, and the receiving mechanism 201 is connected to the discharge pipe 101. The bag-in-bag-out unloading unit 2 is fitted over the outside of the receiving mechanism 201 and connected to the discharge pipe 101. Then, the volume of the receiving mechanism 201 is reduced by the deformable component 2011, completing the material replacement operation. The entire unloading and loading process is conducted in a closed environment, minimizing the contact between waste 100 and the outside air, and preventing dust from flying. Personnel do not have direct contact with waste 100, thus reducing safety risks. Furthermore, the double-sealed and integrally movable containment mechanism 201 and bag-in-bag-out unloading unit 2 further reduce the exposure of waste 100 to the external environment, minimizing secondary pollution. The deformable component 2011 spatially displaces waste 100, moving it from the top to the bottom of the containment mechanism 201, resulting in a larger opening at the top of the containment mechanism 201, facilitating sealing operations and improving unloading safety.

[0036] In one specific embodiment, the receiving mechanism 201 includes a discharge bucket 2012, and a deformable component 2011 is disposed at the bottom of the discharge bucket 2012. Specifically, the deformable component 2011 can be an air bladder with an air supply pipe. The bottom of the discharge bucket 2012 has a through hole through which the air supply pipe passes. The dry adsorption device also includes a pressure regulating unit 205, which can be an air pump capable of regulating the air pressure of the air bladder. The air supply pipe is connected to the pressure regulating unit 205. The pressure regulating unit 205 is disposed outside the bag-in-bag-out discharge unit 2. The bottom of the bag-in-bag-out discharge unit 2 also has a through hole, and the air supply pipe passes sequentially through the through hole at the bottom of the discharge bucket 2012 and the through hole at the bottom of the bag-in-bag-out discharge unit 2, connecting to the pressure regulating unit. The through hole of the bag-in-bag-out discharge unit 2 is tightly sealed to the air supply pipe to prevent leakage of internal dust and harmful gases. During unloading, the air pressure regulating unit 205 first inflates the airbag. At this time, the bottom of the unloading bucket 2012 is occupied by the airbag, while the upper middle part of the unloading bucket 2012 is empty, resulting in a smaller volume for the unloading bucket 2012. The partition plate 202 is then opened, allowing waste to fall into the unloading bucket 2012. Because the airbag is inflated, all the waste accumulates in the upper middle part of the unloading bucket 2012. The partition plate 202 is then closed, separating the filter media bed 1 from the receiving mechanism 201. Waste 100 will no longer enter the receiving mechanism, thus the amount of waste 100 in the receiving mechanism remains fixed. Then, the air pressure regulating unit 205 deflates the airbag. The bottom of the unloading bucket 2012 is empty (the thickness of the airbag is negligible), and the waste 100 in the upper middle part of the unloading bucket 2012 moves downward under gravity, occupying the position of the previously inflated airbag. This leaves a larger space at the opening of the unloading bucket 2012, facilitating sealing operations and reducing the risk of waste leakage, thus lowering the safety risks for operators. After the unloading bucket 2012 is sealed, the airbag is separated from the air pressure regulating unit 205, and the through hole at the bottom of the bag-in-bag-out unloading unit 2 is tightened. After the opening of the bag-in-bag-out unloading unit 2 is tightened and separated from the discharge pipe 101, the sealed unloading bucket 2012 and the bag-in-bag-out unloading unit 2 are removed as a whole for waste disposal.

[0037] Figure 2 This is a schematic diagram of the unloading bucket and deformable assembly provided in one embodiment of this application. In one embodiment, the airbag can be a balloon or an accordion-type airbag (e.g., Figure 2 (as shown), or other shapes of airbags. This application does not impose specific limitations on the form of the airbag. The airbag is preferably an accordion-type airbag. When the accordion-type airbag contracts and expands, the deformation direction is more regular, and the deformation direction is roughly perpendicular to the bottom of the unloading barrel 2012. The waste 100 is less likely to fall between the airbag and the bottom wall of the unloading barrel 2012, thus affecting the removal of the waste 100.

[0038] Figure 3An assembly diagram of the unloading bucket and the first connecting assembly provided for one embodiment of this application is shown below. Figure 1 and Figure 3 As shown, in a further embodiment, the receiving mechanism 201 further includes a first connecting component, which is disposed at the opening of the unloading barrel 2012. The first connecting component is used to fix the unloading barrel 2012 to the discharge pipe 101. Specifically, the first connecting component includes a connecting body 203, a first sealing ring 2031, and a buckle 2032. One end of the connecting body 203 is fixedly connected to the discharge pipe 101, and the other end is detachably connected to the unloading barrel 2012. Since the diameter of the discharge pipe 101 is smaller than the diameter of the unloading barrel, the connecting body 203 can be funnel-shaped, with the smaller diameter end connected to the discharge pipe 101 and the larger diameter end connected to the unloading barrel 2012. The first sealing ring 2031 is disposed between the unloading barrel 2012 and the connecting body 203 to improve sealing. The clip 2032 is installed on the edge of the connector body 203 facing the unloading bucket 2012. The clip 2032 is used to fix the connector body 203 to the unloading bucket 2012.

[0039] In a further embodiment, the connector body 203 is provided with an insertion port 2033, and the insertion port 2033 is detachably provided with a cover plate 206. The cover plate 206 is used to close the unloading barrel 2012. The cover plate 206 can be inserted into the connector body 203 through the insertion port 2033 and cover the unloading barrel 2012. Specifically, the cover plate 206 is placed inside the bag inlet / outlet unloading unit 2. A boss 20121 can be provided on the inner wall of the unloading barrel 2012 near the outlet. The boss 20121 is arranged circumferentially around the unloading barrel 2012. After the cover plate 206 is inserted into the connector body 203, it can be mounted on the boss 20121 to close the unloading barrel 2012. A second sealing ring 2061 may be provided on the side of the boss 20121 facing the opening of the unloading hopper 2012. When the cover plate 206 is closed on the unloading hopper 2012, the second sealing ring 2061 is located between the boss 20121 and the cover plate 206. The operation of inserting the cover plate 206 into the connector body 203 is a bag-separation operation to prevent harmful gases and dust from leaking out of the bag.

[0040] Continue to refer to Figure 3 In one embodiment, the insertion port 2033 may be provided with a sealing element 2034. This sealing element 2034 can be a plastic sheet, which is flexible yet possesses a certain degree of rigidity, capable of deforming under external force and rebounding when no external force is applied. When the cover plate 206 is not inserted, the sealing element 2034 covers the insertion port 2033, sealing it. When the sealing element 2034 is inserted, it deforms, opening the insertion port 2033. When the sealing element 2034 enters the connector body 203, it returns to its initial shape, resealing the insertion port 2033.

[0041] In the above embodiments, the first connecting component is made of a rigid material. Figure 4 A structural diagram of a dry adsorption device provided for another embodiment of this application is shown below. Figure 4 As shown, to facilitate the closure of the receiving mechanism 201, in another embodiment, the receiving mechanism 201 further includes a second connecting component. The second connecting component includes a flexible sleeve 204 and a cable tie (not shown in the figure). One end of the flexible sleeve 204 is fixedly connected to the unloading bucket 2012, and the other end is sleeved on the discharge pipe 101. The cable tie is fixedly connected to the outer wall of the flexible sleeve 204 for tightening the flexible sleeve 204. After the deformable component shrinks and the waste material 100 falls into the bottom of the unloading bucket 2012, the flexible sleeve 204 is tightened with the cable tie, and then the flexible sleeve 204 is separated from the discharge pipe 101, so that the waste material 100 is completely sealed in the unloading bucket 2012, with good sealing performance. Then the opening of the bag-in-bag-out unloading unit 2 is tightened and separated from the discharge pipe 101 to achieve double sealing. In other embodiments, the cable tie can also be detachably connected to the flexible sleeve 204.

[0042] Continue to refer to Figure 3 In one embodiment, the dry adsorption device further includes a base 3 for supporting the unloading bucket 2012. The base 3 may have a groove, and the bottom of the unloading bucket 2012 is embedded in the groove to reduce the possibility of the bucket 2012 tipping over due to shaking under the impact of the waste material 100 during unloading. It is worth noting that the bag-in / bag-out unloading unit 2 ( Figure 3 (Not shown) Together with the unloading bucket 2012, it is placed in the groove of the base 3 for unloading operation. Since the unloading unit 2 of the bag in and bag out unloading unit is flexible, it does not affect the embedding of the unloading bucket 2012 in the groove.

[0043] In other embodiments, the base 3 may further include a base body 301 and an adjustable fixing component 302 disposed on the base body. The fixing component 302 is disposed around the unloading barrel 2012 and includes a connecting seat 3021 connected to the base body 301 and a screw 3022. When the unloading barrel 2012 is placed on the base 3, the unloading barrel 2012 and the bag in / out unloading unit 2 outside it are clamped by adjusting the screw 3022.

[0044] Figure 5 A structural diagram of a dry adsorption device provided for another embodiment of this application. Figure 6 A structural diagram of the dry adsorption device provided in one embodiment of this application when waste falls into the bottom of the flexible discharge bag, as shown. Figure 5 and Figure 6As shown, in another embodiment, the receiving mechanism 201 includes a flexible discharge bag, the opening of which is detachably connected to the discharge pipe 101. Specifically, in this embodiment, the flexible discharge bag replaces the rigid discharge bucket 2012. The flexible discharge bag is filled with air. Since the flexible discharge bag can deform, the air content in the bag changes by changing its shape; the air in the bag can be considered as a deformable component 2011. In the initial state, the lower middle part of the flexible discharge bag, together with the external bag-in-bag-out discharge unit 2, is tied together with a cable tie to expel some air, thereby reducing the volume of the flexible discharge bag. The partition plate 202 is opened, allowing the waste 100 to fall into the flexible discharge bag under gravity, at which point the waste 100 accumulates in the upper middle part of the flexible discharge bag. Then the partition plate 202 is closed, and the cable tie is removed, at which point the waste moves towards the bottom of the flexible discharge bag under gravity. At this point, there is no waste at the opening of the flexible discharge bag. This provides sufficient space to tie the opening tightly. After tying the opening of the flexible discharge bag together with the external bag inlet / outlet discharge unit 2, separate the flexible discharge bag from the discharge pipe 101 and remove the whole bag. During filling, load new filter media 100 from the top of the filter media filling bed 1, and then tie the lower middle part of the flexible discharge bag to complete the material replacement.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
