Description

Technical Field

[0001] This invention relates to the field of chemical waste gas treatment technology, and in particular to a safe treatment device for chemical waste gas filtration. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. Combustion is a method that uses thermal oxidation to convert the combustible and harmful components in waste gas into harmless substances or substances that are easily further treated and recovered. Industrial production processes easily generate volatile organic compounds (VOCs), requiring the use of combustion methods for treatment.

[0003] Some waste gas combustion treatment equipment, when treating organic waste gas, first passes the organic waste gas through a pretreatment device to absorb large particles and high-boiling-point substances in the waste gas. This involves passing the waste gas through a coarse particle filter, a fine particle filter, and an activated carbon layer in sequence to absorb large particulate impurities, small particulate impurities, and high-boiling-point organic waste gas. The waste gas then enters the zeolite rotor device. After the waste gas enters the zeolite rotor device, the air passes through the zeolite adsorption zone, enriching the organic waste gas on the zeolite surface. The purified gas is then discharged into the atmosphere. The zeolite that has adsorbed organic gas rotates to the desorption zone, where a small amount of hot air in the opposite direction desorbs and regenerates the organic gas from the zeolite, concentrating the low-concentration waste gas into a high-concentration waste gas, which is then burned in the combustion chamber.

[0004] The applicant has discovered that the existing technology has at least the following technical problems: After prolonged use, impurities may accumulate on the zeolite surface, including high-boiling-point organic and inorganic impurities. These impurities can clog the honeycomb-like filter pores on the zeolite surface, leading to a large pressure difference across the zeolite and making it difficult to treat industrial waste gas. The zeolite requires disassembly and cleaning or replacement, which necessitates the use of professional technicians from the manufacturer, resulting in high maintenance costs. Therefore, we propose a safe treatment device for chemical waste gas filtration. Summary of the Invention

[0005] The purpose of this invention is to provide a safe treatment device for filtering chemical waste gas, thereby solving the technical problems of existing technologies where zeolite adsorbs impurities and is difficult to clean, resulting in high maintenance costs.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0043] In the description of this invention, it should be understood that the terms "center," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0044] In existing technologies, after prolonged use, zeolite surfaces may accumulate impurities, including high-boiling-point organic and inorganic impurities. These impurities can clog the honeycomb-like filter pores on the zeolite surface, resulting in a large pressure difference across the zeolite and making it difficult to treat industrial waste gas. The zeolite casing needs to be disassembled for cleaning or replacement, which requires professional technicians from the manufacturer, resulting in high maintenance costs.

[0045] This invention provides a safe treatment device for filtering chemical waste gas. High-pressure hot gas is used for desorption at the bottom of the zeolite to desorb most high-boiling-point organic impurities and flush out inorganic impurities from the honeycomb pores. This allows the zeolite to work better, thereby extending the zeolite replacement and cleaning cycle and reducing equipment maintenance costs.

[0046] The following is combined Figures 1-11 The technical solution provided by this invention will be described in more detail below.

[0047] Example 1

[0048] like Figures 1-10 As shown, this embodiment provides a safety treatment device for filtering chemical waste gas, including: a housing 1, a support 2 rotatably connected inside the housing 1, and multiple zeolite rotor blocks 3 centrally symmetrically distributed on the support 2; see also Figure 5 , Figure 5 Several zeolite wheel blocks 3 are omitted from the support 2. The support 2 is divided into multiple fixed positions, and each fixed position is fixed with a zeolite wheel block 3. In this way, the zeolite wheel blocks 3 are set at intervals around the support 2.

[0049] Drive component 5 is connected to support 2 and is used to drive support 2 and zeolite rotor block 3 to rotate; see also Figure 4 The drive component 5, drive bracket 2 and zeolite wheel block 3 rotate. The drive component 5 includes a motor 51 fixedly connected to the outer shell 1. The free end of the output shaft of the motor 51 is fixedly connected to a gear 52. The outer side of the bracket 2 is fixedly connected to a gear ring 53. The gear 52 meshes with the gear ring 53.

[0050] See Figure 4 The outer shell 1 and the support 2 equipped with the zeolite rotor block 3 are separated into two independent cavities: a first cavity 11 and a fourth cavity 14. The support 2 equipped with the zeolite rotor block 3 is further separated into two independent cavities: a second cavity 12 and a third cavity 13. (See also...) Figure 4 The support 2 is provided with at least partially mutually fitted first partition 42 and second partition 43. The second cavity 12 is formed by the first partition 42 and the support 2 equipped with zeolite rotor blocks 3. The third cavity 13 is formed by the second partition 43 and the support 2 equipped with zeolite rotor blocks 3. Figures 2-4As shown, both the first partition 42 and the second plate include vertically arranged plates. Figure 4 (as shown) and horizontally arranged plates ( Figure 2 and Figure 3 As shown). Figure 4 In the first cavity 11, the second cavity 12, the third cavity 13, and the fourth cavity 14, adjacent cavities are connected by honeycomb-shaped holes on the zeolite rotor block 3; see also Figures 1-4 As shown, the tops of the first cavity 11, the second cavity 12, the third cavity 13, and the fourth cavity 14 are sequentially connected to an intake pipe 8, an exhaust pipe 9, an intake pipe 10, and an exhaust pipe 15; see also Figure 6 and Figure 7 The second intake pipe 10 is used to introduce high-pressure hot gas, and the outlet of the second intake pipe 10 is set towards the zeolite rotor block 3; the first intake pipe 8 pours the waste gas to be treated into the first chamber 11, and the waste gas enters the second chamber 12 through the honeycomb holes on the zeolite rotor block 3. The filtered gas is discharged from the first exhaust pipe 9, completing the adsorption of the waste gas; at this time, hot air is introduced into the second intake pipe 10 and the third chamber 13 to desorb the organic gas on the zeolite rotor block 3, so that the organic gas enters the fourth chamber 14 (entering through the honeycomb holes on the zeolite rotor block 3), and finally the organic gas is discharged into the subsequent process through the second exhaust pipe 15.

[0051] See Figure 4 and Figure 6 The moving mechanism 4, located within the third cavity 13, is connected to the support 2 via a transmission mechanism. It drives the second air inlet pipe 10 to move under the influence of the support 2, thereby desorbing the zeolite rotor block 3 with high-pressure hot gas. The high-pressure hot gas flowing out of the second air inlet pipe 10 desorbs the zeolite rotor block that has rotated to the third cavity 13. The moving mechanism 4 pushes the second air inlet pipe 10 along the surface of the zeolite rotor block 3, bringing the outlet of the second air inlet pipe 10 into contact with the surface of the zeolite rotor block 3. Through air pressure and localized high temperature, the high-boiling-point organic gas at the bottom of the zeolite rotor block 3 is more easily desorbed from the zeolite. Furthermore, most solid particulate impurities can be blown out of the zeolite.

[0052] In this embodiment, the chemical waste gas filtration and safety treatment device enters the first chamber 11 through the inlet pipe 8. Organic and inorganic impurities are adsorbed by the zeolite roller blocks 3 and then enter the second chamber 12 through the honeycomb holes on the zeolite roller blocks 3, and are discharged from the exhaust pipe 9. High-pressure hot gas enters the third chamber 13 through the inlet pipe 10. As the support 2 drives the zeolite roller blocks to rotate, the moving mechanism 4 drives the inlet pipe 10 to move, which can desorb high-boiling-point organic impurities on each zeolite roller block and flush out inorganic impurities from the honeycomb holes. The zeolite roller blocks 3 can work better, thereby extending the replacement and cleaning cycle of the zeolite roller blocks 3 and reducing the maintenance cost of the equipment.

[0053] As an optional implementation, the moving mechanism 4 of this embodiment includes a frame 41 and a pushing component, wherein: the frame 41 is fixed to the air outlet end of the second air inlet pipe 10, the frame 41 is connected to the pushing component, the support 2 can drive the pushing component to move vertically upward when it rotates, and the pushing component can descend to the bottom of the third cavity 13 when it moves to the set position.

[0054] When the push component moves upward, it is fixedly connected to the frame 41, thus driving the second air inlet pipe 10 to rise. As the support 2 and zeolite wheel blocks 3 rotate, the high-pressure hot air flowing out of the second air inlet pipe 10 continuously rises, desorbing all the zeolite wheel blocks 3 on the support 2. Furthermore, since the push component can descend to the bottom of the third chamber 13 when it reaches the set position, it facilitates further desorption of the zeolite wheel blocks 3, allowing the zeolite to work better, thereby extending the zeolite replacement and cleaning cycle and reducing equipment maintenance costs.

[0055] To facilitate the stable raising or lowering of the second intake pipe 10, as an optional implementation, see [link to implementation details]. Figure 6 A rod 47 is fixed on one side of the frame 41, and a groove 44 is provided on the side wall of the third cavity 13. The rod 47 is inserted into the groove 44 and slidably connected to the groove 44. A guide ring 45 is fixed on the other side of the frame 41, and a slide rod 46 is fixed in the third cavity 13 (in this embodiment, the slide rod 46 is fixed on the horizontal plate of the second partition 43). The slide rod 46 is inserted into the guide ring 45 and the two are slidably connected.

[0056] One side of the frame 41 is slidably connected to the side wall of the third cavity 13 through the cooperation structure of the sliding groove 44 and the insertion rod 47, and the other side of the frame 41 is slidably connected to the side wall of the third cavity 13 through the cooperation mechanism of the guide ring 45 and the sliding rod 46. With this configuration, the frame 41 and the second air intake pipe 10 can rise and fall stably.

[0057] After the exhaust gas enters the device, the organic impurities inside are mainly deposited at the bottom of the zeolite rotor block 3 due to gravity. Usually, the bottom of the zeolite rotor block 3 adsorbs more organic and inorganic impurities.

[0058] Considering the above issues, see Figure 6 As shown, both the slide groove 44 and the slide rod 46 are inclined. When the second air inlet pipe 10 moves upward, the frame 41 moves along the length direction of the slide groove 44 and the slide rod 46, and the air outlet of the second air inlet pipe 10 gradually moves away from the surface of the zeolite rotor block 3.

[0059] With this configuration, when frame 41 is at the bottom, the outlet of inlet pipe 2 10 is in contact with the surface of zeolite rotor block 3, which facilitates heating the bottom of zeolite rotor block 3. Secondly, it allows for greater air pressure from the bottom-mounted zeolite rotor block 3, thus facilitating the desorption of particles and high-boiling-point organic gases at the bottom of the zeolite rotor block 3. (See also...) Figure 6 and Figure 7 During the upward movement of the second air inlet pipe 10, the outlet of the second air inlet pipe 10 gradually moves away from the surface of the zeolite rotor block 3, thereby providing heat preservation for the fourth chamber 14. This facilitates the heating and desorption of the entire zeolite rotor block 3 (the upper part of the zeolite rotor block 3 has fewer organic and inorganic impurities compared to the lower part, so the outlet of the second air inlet pipe 10 does not need to be attached to the zeolite rotor block 3 that has rotated to the third chamber 13). This allows for convenient heating and desorption of the bottom zeolite rotor block 3, as well as heating and desorption of the entire zeolite rotor block 3, making the equipment easier to use.

[0060] As the air outlet of the second air inlet pipe 10 gradually moves away from the surface of the zeolite rotor block 3 during its ascent, in order to improve the heating effect on the zeolite rotor block 3 that moves into the third cavity 13, as an optional implementation method, see [link to implementation details]. Figure 4 The third cavity 13 is divided into an independent heat storage area 16, and the second air inlet pipe 10 is located outside the heat storage area 16. The aforementioned heat storage area 16 is enclosed by the third partition 29 and the second partition 43.

[0061] Specifically, the second partition 43 is fixedly connected to the third partition 29, and the aforementioned heat storage area 16 is enclosed by the third partition 29 and the second partition 43. The third partition 29 is located at the clockwise position of the support 2, and the slide groove 44 is located on the third partition 29. The third partition 29 and the second partition 43 form a small area, which is the aforementioned heat storage area 16. The heat storage area 16 makes it easier to heat the zeolite rotor block 3 that moves into the third cavity 13, reducing some heat loss. Secondly, it facilitates timely heat dissipation of the zeolite rotor block 3 after desorption, which is convenient for the subsequent adsorption of organic gases, thereby facilitating the desorption of the zeolite rotor block 3 by the second air inlet pipe 10.

[0062] In this embodiment, the chemical waste gas filtration and safety treatment device also includes a transmission mechanism 6, which is located inside the second cavity 12. The transmission mechanism 6 connects the support 2 and the pushing component. The transmission mechanism 6 can drive the pushing component to rise and lower.

[0063] As an alternative implementation, see [link to implementation details]. Figure 6 , Figure 7 and Figure 8As shown, the transmission mechanism 6 includes a rubber roller 61 (which can be a silicone rubber roller), a transmission shaft 63, a collar 18, a high-temperature magnet 65, and a limiting groove 66. Specifically: the rubber roller 61 is rotatably connected to the outer shell 1, and the rubber roller 61 is attached to the bracket 2 equipped with the zeolite wheel block 3. Rotation of the bracket 2 can push the rubber roller 61 to rotate. The transmission shaft 63 is rotatably connected to the outer shell 1. A gear 62 is connected to the bottom of the rubber roller 61, and a gear 64 is connected to the bottom of the transmission shaft 63. The gear 64 meshes with the gear 62. The collar 18 is sleeved on the transmission shaft 63, and the high-temperature magnet 65 is fixedly connected to the collar 18. The limiting groove 66 is fixed to the side wall of the second cavity 12. For details, see [link to documentation]. Figure 6 and Figure 7 The limiting groove 66 is located on the first partition plate 42 and is set vertically. The high-temperature magnet 65 is located in the limiting groove 66 and is slidably connected to the limiting groove 66. The high-temperature magnet 65 is magnetically attracted to the pushing component. The collar 18 can move up and down along the transmission shaft 63 when the transmission shaft 63 rotates, thereby driving the high-temperature magnet 65 and the pushing component to move up and down.

[0064] In the above structure, when the bracket 2 rotates, it uses friction to drive the rubber roller 61 to rotate. The winch roller drives the transmission shaft 63 to rotate through the cooperation structure of gear 1 62 and gear 2 64. When the transmission shaft 63 rotates, the collar 18 moves up and down along the transmission shaft 63. When the collar 18 moves upward along the transmission shaft 63, it drives the high-temperature magnet 65 to move upward, causing the push assembly to move upward, thereby causing the second air intake pipe 10 to move upward. The same applies when the collar 18 moves downward along the transmission shaft 63.

[0065] In addition, after being squeezed by the rubber roller 61, the zeolite rotor block 3 can vibrate relative to the support 2, which makes it easier to separate the high-boiling-point organic gases and particles on the surface of the zeolite rotor block 3 from the zeolite rotor block 3, and makes subsequent desorption easier.

[0066] As an alternative implementation, see [link to implementation details]. Figure 7 The driving assembly includes an iron block 69, a guide rod 67, and a guide cylinder 68. The guide rod 67 is fixedly connected to the frame 41, slidably connected to the guide cylinder 68, and fixedly connected to the iron block 69. The iron block 69 is magnetically attracted to the high-temperature magnet 65. When the collar 18 moves upward along the drive shaft 63, it drives the high-temperature magnet 65 upward, causing the iron block 69, guide cylinder 68, guide rod 67, frame 41, and intake pipe 10 to move upward. Because the intake pipe 10 and frame 41 move upward at an angle, and the guide rod 67 and guide cylinder 68 are slidably connected, the movement of the intake pipe 10 and the power transmission are not affected.

[0067] This embodiment provides a specific implementation method in which the collar 18 can move up and down along the drive shaft 63 when the drive shaft 63 rotates:

[0068] See Figures 6-9 A connecting block 19 and an electromagnet 22 are fixed on the collar 18. The drive shaft 63 has a spiral groove 17, and a pin 191 (e.g., ...) is fixed to the side of the connecting block 19 facing the drive shaft 63. Figure 9 Electromagnet 22 is located on the side of connecting block 19 opposite to drive shaft 63 (e.g.) Figure 9 The electromagnet 22 has an energized state and an de-energized state. In the de-energized state, the insert 191 is inserted into the spiral groove 17, and the collar 18 is connected to the drive shaft 63, causing the collar 18 to rise when the drive shaft 63 rotates. In the energized state, the electromagnet 22 and the connecting block 19 are magnetically attracted, the insert 191 separates from the spiral groove 17, and the collar 18 separates from the drive shaft 63, causing the collar 18 to descend under gravity. For details, see [link to details]. Figure 9 The upper surface of the collar 18 is provided with a switch 23, see [reference]. Figure 10 A switch 24 is provided on the lower surface of the collar 18, see [reference]. Figure 8 A trigger ring 25 is provided on the upper part of the drive shaft 63; when the collar 18 rises to the position where the trigger ring 25 presses the switch 23, the electromagnet 22 is energized; when the collar 18 descends under the action of gravity to the position where the outer casing 1 presses the switch 24, the electromagnet 22 is de-energized; see also Figure 9 A first spring 20 is provided between the connecting block 19 and the electromagnet 22. When the electromagnet 22 is de-energized, the first spring 20 pushes the insert 191 on the connecting block 19 into the spiral groove 17. See also Figure 9 The connecting block 19 and the electromagnet 22 are slidably connected by the limiting rod 21 to ensure the stability of the structure.

[0069] During equipment operation, motor 51 first drives gear 3 52 to rotate, gear 3 52 drives gear ring 53 to rotate, gear ring 53 drives bracket 2 to rotate, bracket 2 drives zeolite rotor block 3 to rotate, and inlet pipe 8 discharges exhaust gas into the first chamber 11. After passing through zeolite rotor block 3, the organic waste gas adheres to zeolite rotor block 3, thus the filtered exhaust gas enters the second chamber 12. Simultaneously with the rotation of bracket 2, bracket 2 squeezes rubber roller 61, thereby driving rubber roller 61 to rotate through friction. The rotation of gear 62 drives gear 64, which in turn drives gear 64. Drive shaft 63 rotates synchronously. Insert post 191 is located in the guide groove. Collar 18 is connected to drive shaft 63. Under the limiting action of limiting groove 66, high-temperature magnet 65 causes collar 18 to rise along spiral groove 17. This causes iron block 69 to rise, which in turn causes guide rod 67, guide cylinder 68, and frame 41 to rise, thus causing intake pipe 10 to rise. Hot air is blown onto the zeolite rotor block 3, filling the third chamber 13 with hot air. This desorbs the zeolite rotor block 3 between the third chamber 13 and the fourth chamber 14, causing the organic gas to concentrate and enter the fourth chamber 14, then exiting through the exhaust pipe 15. When the collar 18 moves to the trigger ring 25, the switch 23 touches the trigger ring 25, energizing the electromagnet 22. The electromagnet 22 attracts the connecting block 19. The high-temperature magnet 65, being too far from the electromagnet 22 and the connecting block 19, cannot attract the magnet. Connecting block 19 drives insert 191 to disengage from guide groove. At this time, drive shaft 63 and collar 18 separate, and first spring 20 is squeezed. At this time, high temperature magnet 65, guide ring 45, iron block 69 and frame 41 fall directly onto the surface of gear 2 64 under the action of gravity. Gear 2 64 contacts switch 24, electromagnet 22 is de-energized, and then first spring 20 pushes connecting block 19 and insert 191 to re-insert into spiral groove 17 of drive shaft 63, so that it can continue to rise.

[0070] See Figure 8 The pitch of the spiral groove 17 gradually increases from bottom to top.

[0071] Since most of the high-boiling-point organic gases and plastic particles are located at the bottom of the zeolite rotor block 3, the bottom pitch of the spiral groove 17 is small, and the rising speed of the collar 18 at the bottom is slow. This allows for better desorption of the high-boiling-point organic matter and plastic particles from the zeolite rotor block 3, extending the zeolite cleaning or replacement time and facilitating cost savings.

[0072] See Figure 5 A second spring 26 is provided between the zeolite wheel block 3 and the support 2. The two ends of the second spring 26 are fixedly connected to the zeolite wheel block 3 and the support 2 respectively, which facilitates the assembly and disassembly of the zeolite wheel block 3 on the support 2.

[0073] Example 2

[0074] This embodiment provides another specific implementation method in which the collar 18 can move up and down along the drive shaft 63 when the drive shaft 63 rotates:

[0075] Unlike Example 1, see [link to example]. Figure 11 In this embodiment, the drive shaft 63 is a bidirectional lead screw 27, the collar 18 is a threaded sleeve 28 with internal threads, the threaded sleeve 28 is threadedly connected to the bidirectional lead screw 27, and the high-temperature magnet 65 is fixedly connected to the threaded sleeve 28.

[0076] Since the drive shaft 63 is a double-acting lead screw 27, and the threaded sleeve 28 is threadedly connected to the double-acting lead screw 27, the threaded sleeve 28 can rise along the drive shaft 63. When it rises to the top of the threaded groove of the double-acting lead screw 27, the threaded sleeve 28 reverses direction and descends. The above structure can also realize that the collar 18 can move up and down along the drive shaft 63 when the drive shaft 63 rotates.
