Description

Technical Field

[0001] This invention relates to the field of VOCs removal technology, specifically to a VOCs removal device for VOCs waste gas treatment technology. Background Technology

[0002] Volatile organic compounds (VOCs) are a major source of air pollution, and their efficient treatment has become an urgent issue in the environmental protection field. Among the many treatment technologies, adsorption is widely used due to its high efficiency and relatively low cost, with activated carbon adsorption devices being one of the mainstream equipment.

[0003] Currently, the fixed-bed activated carbon adsorption towers commonly used in industry typically employ a batch operation mode with two or more towers connected in parallel. That is, when the activated carbon in one adsorption tower becomes saturated, a valve is used to switch the waste gas to another regenerating activated carbon tower for treatment, while the saturated tower enters the desorption and regeneration stage. While this operation method is effective, it has inherent drawbacks: First, the utilization efficiency of the activated carbon layer is low; logically, the utilization efficiency of the lower activated carbon layer cannot be higher than that of the upper activated carbon layer in the same amount of time. Second, the desorption of the activated carbon layer is also a centralized process, which leads to mutual obstruction between the activated carbon layers, resulting in low desorption efficiency.

[0004] To address the challenges of continuous operation, the industry has developed rotary adsorption technologies, such as rotary concentrators. This technology uses a honeycomb-shaped rotor as the adsorption medium. Through the slow rotation of the rotor, adsorption, desorption, and cooling processes occur simultaneously in different zones within the device. However, this technology also has drawbacks: First, the rotor itself is a monolithic structure, meaning any damage to any part requires replacement of the entire rotor, resulting in high maintenance costs. Second, its core dynamic and static seals typically use elastic material contact seals, which are prone to wear during long-term operation, leading to "cross-contamination" between the adsorption and desorption zones. This means that high-concentration desorbed waste gas leaks into the low-concentration adsorption zone, interfering with the adsorption process and affecting final emission compliance. Third, the filtration path of the rotary concentrator is fixed and cannot be adaptively adjusted according to changes in waste gas concentration or operating conditions, resulting in insufficient flexibility. Summary of the Invention

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-12 This invention provides a technical solution: a VOCs removal device for VOCs waste gas treatment technology, including an adsorption chamber 1, a shielding cover 2 provided on the front side of the adsorption chamber 1, a hollow fixing rod 3 fixedly installed inside the adsorption chamber 1, fixing side plates 4 fixedly installed on the front and rear sides of the hollow fixing rod 3, an array of mounting brackets 5 fixedly installed on the fixing side plates 4, the mounting brackets 5 fixedly installed inside the adsorption chamber 1, a rotating ring 6 rotatably installed on the hollow fixing rod 3, an array of mounting frames 7 installed on the rotating ring 6, an activated carbon plate 8 fixedly installed inside the mounting frame 7, a first solenoid valve 12 provided on the lower side of the adsorption chamber 1, a second solenoid valve 13 provided on the side of the adsorption chamber 1, and a second air inlet pipe 14 fixedly installed on the upper side of the adsorption chamber 1;

[0036] The sealing mechanism 9 includes a first sealing strip 903 and a second sealing strip 904. The first sealing strip 903 is movably disposed on the upper side of the mounting bracket 5, and the second sealing strip 904 is movably disposed on both sides of the mounting bracket 5. The first sealing strip 903 and the second sealing strip 904 abut against the outer side of the mounting frame 7.

[0037] The switching mechanism 10 includes a ring rack 1003, a gear 1004 and a rotary motor 1005. The ring rack 1003 is fixedly installed on one side of the rotating ring 6, and the rotary motor 1005 is fixedly installed on one side of the adsorption chamber 1. The gear 1004 is fixedly installed on the output shaft of the rotary motor 1005, and the gear 1004 meshes with the ring rack 1003.

[0038] The desorption mechanism 11 includes a loading chamber 1101 and a sealing plate 1103. The loading chamber 1101 is fixedly installed on one side of the cover 2. Two sets of sealing plates 1103 are movably inserted into the loading chamber 1101. The sealing plates 1103 are inserted on one side of the two sets of activated carbon plates 8 on the lower side.

[0039] This equipment adjusts the filtration sequence of the activated carbon plates 8 by rotating them, allowing for efficient utilization of the activated carbon plates 8 and different surfaces of the plates, thus further increasing their utilization efficiency. The equipment is also equipped with a sealing mechanism 9 for sealing the activated carbon plates 8, and a desorption mechanism 11 for sealing and desorbing the activated carbon plates 8. Due to the unique characteristic of the activated carbon plates 8 being able to rotate, the equipment has the feature of simultaneous adsorption and desorption, which can significantly extend the service life of the activated carbon plates 8 and enhance the functionality of the equipment.

[0040] Furthermore, the sealing mechanism 9 also includes a first movable groove 901, a second movable groove 902, and a locking groove 905. The first movable groove 901 is provided on the upper side of the mounting bracket 5, and the second movable groove 902 is provided on the side of the mounting bracket 5. The first sealing strip 903 moves in the first movable groove 901, and the second sealing strip 904 moves in the second movable groove 902. The locking groove 905 is provided at the upper corner of the mounting frame 7. The shape of the first sealing strip 903 is adapted to the shape of the upper side of the mounting frame 7. This structure is a sealing structure between the activated carbon plate 8 and the adsorption chamber 1. The first sealing strip 903 and the second sealing strip 904 seal the activated carbon plate 8 by fitting together with the mounting frame 7. The shape of the second sealing strip 904 covers the corners of the mounting frame 7, and the second sealing strip 904 is superimposed on the first sealing strip 903 to achieve a superimposed seal. This gives the first sealing strip 903 and the second sealing strip 904 a good sealing effect on the activated carbon plate 8. In addition to sealing, the sealing of the mounting frame 7 by fitting together also has the effect of positioning the activated carbon plate 8, which can effectively increase the stability of the equipment during use.

[0041] Furthermore, the sealing mechanism 9 also includes a movable plate 906, a limiting groove 907, a limiting block 908, a guide rod 909, a first airbag 910, a second airbag 911, a connecting pipe 912, a venting ring 913, a venting pipe 914, and a first air inlet pipe 915. A movable plate 906 is fixedly installed on the first sealing strip 903 and the second sealing strip 904. Limiting grooves 907 are arrayed on the inner sides of both the first movable groove 901 and the second movable groove 902. A limiting block 908 is fixedly installed on the movable plate 906, and the limiting block 908 slides within the limiting groove 907. A guide rod 909 is fixedly installed within the limiting groove 907, and the limiting block 908 is movably sleeved on the guide rod 909. On the rod 909, a first airbag 910 is fixedly installed in the first movable groove 901, and a second airbag 911 is fixedly installed in the second movable groove 902. The first airbag 910 is fixedly installed on the movable plate 906 on the first sealing strip 903, and the second airbag 911 is fixedly installed on the movable plate 906 on the second sealing strip 904. The first airbag 910 and the second airbag 911 are connected by a connecting pipe 912. A ventilation ring 913 is fixedly installed on the outside of the adsorption chamber 1. A ventilation pipe 914 is fixedly installed in an array inside the ventilation ring 913. The ventilation pipe 914 is connected to the first airbag 910. A first air inlet pipe 915 is fixedly installed on one side of the ventilation ring 913. The function of this structure is to control the extension and retraction of the first sealing strip 903 and the second sealing strip 904 through air pressure, so that the first sealing strip 903 and the second sealing strip 904 can tightly press the mounting frame 7, or they can retract into the first movable groove 901 and the second movable groove 902 under the action of air pressure. This prevents the mounting frame 7 from contacting the first sealing strip 903 and the second sealing strip 904 when rotating, and prevents obstruction when the activated carbon plate 8 switches states. At the same time, it can also realize the synchronous movement of multiple sets of first sealing strips 903 and second sealing strips 904, increasing the stability of the equipment during use.

[0042] Furthermore, the sealing mechanism 9 also includes an air box 916 and an air-blocking block 917. Two sets of air boxes 916 are fixedly installed in the first movable groove 901, and the air boxes 916 are connected to the air connecting pipe 912. Two sets of air-blocking blocks 917 are fixedly installed on the movable plate 906 on the first sealing strip 903, and the air-blocking blocks 917 are movably inserted into the air boxes 916. This structure controls the expansion sequence of the first airbag 910 and the second airbag 911. When the first sealing strip 903 and the second sealing strip 904 retract into the first movable groove 901 and the second movable groove 902, the air-blocking block 917 is completely inserted into the air box 916, preventing the first airbag 910 and the second airbag 911 from communicating. Therefore, when air is injected into the first airbag 910 and the second airbag 911, the vent ring 913 can expand first, causing the first sealing strip 903 to descend first, thus completing the superimposed sealing of the first sealing strip 903 and the second sealing strip 904, increasing the stability of the equipment during use.

[0043] Furthermore, the switching mechanism 10 also includes an annular groove 1001 and a connecting column 1002. An annular groove 1001 is formed on one side of the hollow fixing rod 3, and a connecting column 1002 is fixedly installed at the annular groove 1001. The connecting column 1002 is fixedly installed on the fixed side plate 4, which is fixedly installed inside the adsorption chamber 1. An annular rack 1003 is rotatably installed inside the annular groove 1001 and on the fixed side plate 4. This structure drives the rotation of the rotating ring 6 and also ensures the sealing between the ventilation groove 1006 and the adsorption chamber 1, allowing the hollow fixing rod 3 to rotate the activated carbon plate 8 while fixed, thus providing conditions for subsequent airway switching.

[0044] Furthermore, the switching mechanism 10 also includes a ventilation groove 1006 and a guide groove 1007. The outer side of the hollow fixed rod 3 and the inner side of the rotating ring 6 are fitted together. The rotating ring 6 has an array of ventilation grooves 1006, and the hollow fixed rod 3 has two sets of guide grooves 1007. The size and position of the guide grooves 1007 are opposite to the size and position of the ventilation grooves 1006. Figure 4 For example, the activated carbon plate 8 divides the space inside the adsorption chamber 1 into six parts. The space at the bottom is the desorption area, the space at the bottom right is the discharge area, and the remaining spaces are all adsorption areas. The gas guide trough 1007 is connected to the space at the bottom left and the discharge area, so as to realize the function of the flue gas bypassing the desorption area and being discharged, which increases the functionality of the equipment when in use.

[0045] Furthermore, the switching mechanism 10 also includes a first insertion slot 1008, an insertion block 1009, a blocking block 1010, and a flange ring 1011. The first insertion slot 1008 is arrayed on the rotating ring 6 and the front fixed side plate 4. The insertion block 1009 is fixedly installed on the lower side of the mounting frame 7. The insertion block 1009 is inserted into the first insertion slot 1008. The shape and size of the insertion block 1009 are adapted to the first insertion slot 1008 opened on the rotating ring 6. The blocking block 1010 is arrayed and fixedly installed on the shielding cover 2. The blocking block 1010 is inserted into the first insertion slot 1008 opened on the fixed side plate 4. The flange ring 1011 is fixedly installed on both the shielding cover 2 and the adsorption chamber 1. The two sets of flange rings 1011 are fixed together by bolts and nuts. This structure is a disassembly structure for the mounting frame 7 and the activated carbon plate 8. When the mounting frame 7 and the activated carbon plate 8 are rotated to be misaligned with the mounting bracket 5, the mounting frame 7 and the activated carbon plate 8 can be directly pulled out after the cover 2 is removed, which makes the activated carbon plate 8 easy to replace and increases the convenience of using the equipment.

[0046] Furthermore, the desorption mechanism 11 also includes a movable shelf 1102, a second insertion slot 1104, a shielding strip 1105, and a telescopic motor 1106. The movable shelf 1102 is movably arranged inside the loading chamber 1101. Two sets of sealing plates 1103 are fixedly installed on the movable shelf 1102. Two sets of second insertion slots 1104 are opened on the shielding cover 2. The sealing plates 1103 are movably inserted into the second insertion slots 1104. The shielding strip 1105 is fixedly installed on the sealing plates 1103. Sealing gaskets are provided at the edges of the sealing plates 1103 and abut against the inner wall of the adsorption chamber 1 and the outer side of the rotating ring 6. The telescopic motor 1106 is fixedly installed on the loading chamber 1101. The output shaft of the telescopic motor 1106 is fixedly installed on the movable shelf 1102. The function of this structure is to use the space at the bottom of the adsorption chamber 1 as the desorption area. Therefore, the sealing plate 1103 is inserted into the adsorption chamber 1 to isolate the space. The sealing of the area is achieved by the sealing plate 1103 fitting with the adsorption chamber 1 and the outer side of the rotating ring 6. The shielding strip 1105 and the movable layer plate 1102 are used to seal the second insertion slot 1104 under different conditions, which increases the stability of the equipment during use.

[0047] Furthermore, the desorption mechanism 11 also includes a long pipe 1107, a trigger air port 1108, and a one-way valve 1109. The long pipe 1107 is fixedly installed on the movable shelf 1102 and inserted into the loading chamber 1101. The trigger air port 1108 is fixedly installed on the movable shelf 1102 and the long pipe 1107 and the trigger air port 1108 are connected. The one-way valve 1109 is fixedly installed on the lower side of the shielding cover 2 and the trigger air port 1108 and the one-way valve 1109 are opposite each other. The function of this structure is to perform desorption by injecting steam and inert gas, which is a conventional desorption process and will not be described in detail here. The one-way valve 1109 can close the adsorption chamber 1. The one-way valve 1109 can only be opened after the trigger gas port 1108 and the one-way valve 1109 come into contact. This is a mature technology. At the same time, when the adsorption chamber 1 is connected to the long pipe 1107, the sealing plate 1103 has already closed the lower space of the adsorption chamber 1, which increases the stability of the equipment during use.

[0048] Furthermore, the space between the first solenoid valve 12 and the two sets of activated carbon plates 8 on the bottom side is opposite, and the space between the second solenoid valve 13 and the two sets of activated carbon plates 8 on the lower right side is opposite. The first solenoid valve 12 is used to discharge the desorbed flue gas, the second solenoid valve 13 is used to discharge the filtered air, and the second air inlet pipe 14 is used to inject flue gas, so that the flue gas can be discharged in different categories, increasing the functionality of the equipment during use.

[0049] Working principle: When this invention is used, flue gas is introduced through the second air inlet pipe 14 and filtered by the activated carbon plate 8. The flue gas is divided into two streams and filtered by the activated carbon plates 8 on the left and right sides. The flue gas on the right side is filtered by the activated carbon plate 8 and then discharged from the second solenoid valve 13. The flue gas on the left side is filtered by the activated carbon plate 8 and then passes through the ventilation groove 1006 and the air guide groove 1007 and is discharged from the second solenoid valve 13. At this time, the two sets of activated carbon plates 8 on the lower side are covered by the sealing plate 1103. The space between the long pipe 1107 and the sealing plate 1103 is connected. Steam is injected for cleaning and discharged from the first solenoid valve 12.

[0050] When switching the activated carbon plate 8, the air pump connected to the first air inlet pipe 915 draws air, causing the first airbag 910 and the second airbag 911 to contract. This causes the first sealing strip 903 and the second sealing strip 904 to be respectively housed in the first movable groove 901 and the second movable groove 902, so that the activated carbon plate 8 is no longer stabilized and sealed. The telescopic motor 1106 drives the movable shelf 1102 to retract into the loading chamber 1101. At this time, the sealing plate 1103 is pulled out, causing the shielding strip 1105 to abut against the second insertion groove 1104, allowing the activated carbon plate 8 to rotate normally. Conversely, it can complete the sealing. The rotary motor 1005 starts, driving the gear 1004 to rotate, which in turn drives the annular rack 1003 to rotate. The rotation of the annular rack 1003 drives the rotating ring 6 to rotate. This causes the activated carbon plate 8 to rotate. After rotating to the appropriate position, the air pump starts and injects air into the first air inlet pipe 915. The gas fills the ventilation ring 913 and is injected into the first air bag 910 through the ventilation pipe 914. Since the air blocking block 917 is inserted in the air box 916 to seal the connecting pipe 912, the first air bag 910 will expand first, causing the first sealing strip 903 to drop and press down on the upper side of the mounting frame 7. The air blocking block 917 is no longer inserted in the air box 916, so the connecting pipe 912 is connected. Then the second air bag 911 expands, causing the second sealing strip 904 to abut against the side of the mounting frame 7 and the first sealing strip 903, completing the sealing of the outside of the mounting frame 7.
