However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0041] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0042] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0043] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0044] like Figures 1 to 7 As shown, a liquid chemical extraction and tail gas absorption integrated extraction device includes a material tank 1, a reaction vessel 2, and a comprehensive tail gas absorption pipe 3. A liquid-gas separator 4 is connected to the material tank 1. The liquid-gas separator 4 includes an outer cylinder 41 and an inner cylinder 42 slidably connected to the outer cylinder 41. A spherical cover 43 is connected to the upper end of the inner cylinder 42. The spherical cover 43 has a spherical cover hole 431. The inner cylinder 42 has a gas flow channel 421 and a liquid flow channel 422. The gas flow channel 421 is connected to the spherical cover 43, and the liquid flow channel 422 is connected to the reaction vessel 2. The spherical cover 43 is connected to the comprehensive tail gas absorption pipe 3 through the spherical cover hole 431.

[0045] In this embodiment, the material tank 1 is used to store liquid chemicals. The liquid flow channel 422 transports the liquid chemicals from the material tank 1 to the reaction vessel 2, where the reaction vessel 2 receives the liquid chemicals from the material tank 1 for subsequent processing. The gas flow channel 421 transports the waste gas from the material tank 1 to the integrated tail gas absorption pipe 3, which collects and treats the waste gas from the material tank 1. The outer cylinder column 41 serves as the track for the inner cylinder column 42 to slide, allowing the inner cylinder column 42 to move to both a sealed and unsealed position during sliding. In the sealed position, the channel between the material tank 1 and the gas flow channel 421 is closed, preventing the waste gas from the material tank 1 from being transported to the integrated tail gas absorption pipe 3. In the unsealed position, the channel between the material tank 1 and the gas flow channel 421 is open, allowing the waste gas from the material tank 1 to be transported to the integrated tail gas absorption pipe 3. The gas flow channel 421 communicates with the interior of the spherical shroud 43, guiding the waste gas towards the spherical shroud 43. A spherical or near-spherical shroud 43 is connected to the top of the inner cylinder 42, and has a shroud hole 431 on its surface. Waste gas is transported to the spherical shroud 43 via the gas flow channel 421, and then flows out through the shroud hole 431 until it enters the integrated tail gas absorption pipe 3. During material extraction, liquid chemicals flow from the material tank 1 through a pipe into the liquid flow channel 422 of the inner cylinder 42, and are then transported to the reactor 2 through corresponding components. Waste gas in the material tank 1 enters the spherical shroud 43 via the gas flow channel 421, and then enters the integrated tail gas absorption pipe 3 through the shroud hole 431. During liquid-gas separation, the sliding of the inner cylinder 42 controls the gas flow. For example, when the liquid level in the material tank 1 is high or the gas content is low, the inner cylinder 42 is moved upwards until the gas flow channel 421 is closed to improve the transport efficiency of the liquid chemicals; when the liquid level decreases and the gas content increases, the inner cylinder 42 descends, and the gas flow channel 421 opens, thereby increasing the flow efficiency of the waste gas. It should be noted that both the reactor 2 and the integrated tail gas absorption pipe 3 are technical means well known to those skilled in the art, and their specific structures will not be described in detail here.

[0046] In some embodiments, the upper end of the material barrel 1 is provided with a first exhaust gas chamber 11, and the first exhaust gas chamber 11 is provided with an exhaust gas passage hole 111, which is used to introduce the exhaust gas in the material barrel 1 into the first exhaust gas chamber 11.

[0047] In this embodiment, the first exhaust gas chamber 11 is located at the upper end of the material barrel 1, and the exhaust gas passage 111 is opened at the bottom of the first exhaust gas chamber 11 to guide the exhaust gas volatilized in the material barrel 1 into the interior of the chamber.

[0048] In some embodiments, one end of the inner cylinder column 42 is located at the bottom of the material tank 1, and the liquid flow channel 422 is located at the bottom of the material tank 1. The liquid flow channel 422 is used to introduce liquid chemicals into the material tank 1. The gas flow channel 421 is located in the middle of the inner cylinder column 42, and the middle of the inner cylinder column 42 is connected to an inner cylinder vent hole 423. The inner cylinder vent hole 423 is located in the first waste gas chamber 11, and the inner cylinder vent hole 423 is used to introduce waste gas from the first waste gas chamber 11 into the gas flow channel 421 of the inner cylinder column 42.

[0049] In this embodiment, the inner cylinder 42 is hollow in the middle, and its bottom is located at the bottom of the material tank 1, allowing the liquid chemicals to flow in the liquid flow channel 422. Utilizing the negative pressure difference during material extraction, the liquid is drawn from the bottom of the material tank 1 into the liquid flow channel 422. Additionally, the gas flow channel 421 is located in the upper part of the inner cylinder 42 and is annularly formed in the middle of the inner cylinder 42. The gas flow channel 421 and the liquid flow channel 422 are independent channels. A spherical shroud 43 is connected to the upper end of the inner cylinder 42, and the spherical shroud 43 is hollow. The gas flow channel 421 communicates with the spherical shroud 43, meaning that exhaust gas directly enters the spherical shroud 43 through the gas flow channel 421. The liquid flow channel 422 carries the liquid chemicals through the spherical shroud 43 and out.

[0050] In some embodiments, a telescopic block 44 is connected to the middle of the inner cylinder 42. The telescopic block 44 is connected to the first exhaust gas chamber 11. The telescopic block 44 is used to seal the outer cylinder 41 in a sealed position to prevent the exhaust gas of the first exhaust gas chamber 11 from entering the gas flow channel 421 of the inner cylinder 42.

[0051] In this embodiment, the telescopic block 44 is connected to the bottom of the first exhaust gas chamber 11. After the inner cylinder 42 moves upward to the point of being closed, the telescopic block 44 is driven to block the outer cylinder 41, so as to block the gas flow channel 421 of the inner cylinder 42 and the material bucket 1, so as to prevent the exhaust gas of the first exhaust gas chamber 11 from entering the gas flow channel 421 of the inner cylinder 42.

[0052] In some embodiments, a sealing gasket 45 is connected to the outer cylinder 41, and the sealing gasket 45 is used to seal the telescopic block 44 and the outer cylinder 41 at the sealing position.

[0053] In this embodiment, the sealing gasket 45 is located at the contact surface between the telescopic plug 44 and the outer cylinder 41. This enhances the sealing effect and reduces the instantaneous force when the telescopic plug and the outer cylinder 41 come into contact.

[0054] In some embodiments, a limiting groove 411 is provided on the outer cylinder 41, and a limiting protrusion 424 is connected to the inner cylinder 42, wherein the limiting protrusion 424 is slidably connected to the limiting groove 411.

[0055] In this embodiment, the limiting groove 411 is provided on the outer cylinder 41, and the limiting protrusion 424 is provided on the inner cylinder 42. The limiting protrusion 424 is slidably connected to the limiting groove 411, thereby ensuring the sliding direction of the inner cylinder 42 on the outer cylinder 41.

[0056] In some embodiments, the upper end of the material barrel 1 is provided with a drive cavity 12, a drive motor 5 is connected inside the drive cavity 12, a drive gear 6 is connected to the drive motor 5, an inner cylinder gear 7 is meshed with the drive gear 6, a thread is provided on the limiting protrusion 424, and the inner cylinder gear 7 is threadedly connected to the inner cylinder column 42 through the thread on the limiting protrusion 424. The drive motor 5 is used to drive the inner cylinder column 42 to achieve the action of rising or falling.

[0057] In this embodiment, the drive chamber 12 is located at the upper end of the material container 1, and also at the upper end of the first exhaust gas chamber 11, providing support and a relatively enclosed space for the drive motor 5 and related components. The drive motor 5 drives the drive gear 6 to rotate, the drive gear 6 drives the inner cylinder gear 7 to rotate, and the inner cylinder gear 7 drives the inner cylinder column 42 to move up and down. Simultaneously, the limiting protrusion 424 is threaded to fit with the inner cylinder gear 7. Furthermore, it should be noted that the limiting protrusion 424 in this application includes, but is not limited to, six protrusions, and can be increased according to actual conditions to better fit with the inner cylinder gear 7.

[0058] In some embodiments, the material tank 1 is provided with a second exhaust gas chamber 13 at its upper end. The second exhaust gas chamber 13 is located at the upper end of the drive chamber 12. The spherical cover 43 is disposed in the second exhaust gas chamber 13. An exhaust gas conduit is connected to the upper end of the second exhaust gas chamber 13. The exhaust gas conduit is used to collect the exhaust gas released by the spherical cover 43 through the spherical cover hole 431 from the second exhaust gas chamber 13 and introduce it into the integrated exhaust gas absorption pipe 3.

[0059] In this embodiment, the second exhaust gas chamber 13 is located above the drive chamber 12, and the second exhaust gas chamber 13 is fitted onto the spherical cover 43. Therefore, the exhaust gas inside the spherical cover 43 diffuses into the second exhaust gas chamber 13. An exhaust gas conduit is connected to the upper end of the second exhaust gas chamber 13, and the exhaust gas conduit communicates with the integrated exhaust gas absorption pipe 3. The spherical cover 43 is provided with a spherical cover hole 431. This allows the exhaust gas inside the spherical cover 43 to be transported to the second exhaust gas chamber 13 and then to the integrated exhaust gas absorption pipe 3.

[0060] In some embodiments, a liquid conduit 8 is connected to the inner cylinder column 42, one end of the liquid conduit 8 is connected to the liquid flow channel 422, and the other end of the liquid conduit 8 is connected to the reaction vessel 2; a chemical pump 9 is connected to the liquid conduit 8.

[0061] In this embodiment, a chemical pump 9 is connected to the liquid conduit 8, which can transport the liquid chemicals in the material tank 1 to the reaction vessel 2. In addition, the chemical pump 9 is a special pump specifically designed for transporting corrosive, highly toxic, high-purity, volatile, or high-viscosity chemical liquids. It is a well-known technology in the art and will not be described in detail here.

[0062] In some embodiments, a one-way air inlet valve 14 is connected to the material tank 1, which is used to input air into the material tank 1 so that the gas in the material tank 1 enters the integrated exhaust gas absorption pipe 3; an air pump 15 is connected to the material tank 1, which is used to input air into the material tank 1 when it is necessary to increase the exhaust gas, so as to further accelerate the gas in the material tank 1 into the integrated exhaust gas absorption pipe 3.

[0063] In this embodiment, a one-way air inlet valve 14 and an air pump 15 are connected to the material tank 1. The one-way air inlet valve 14 is used to input air into the material tank 1 so that the gas inside the material tank 1 enters the integrated exhaust gas absorption pipe 3. The air pump 15 can pump external air into the material tank 1 to increase the speed at which the exhaust gas enters the integrated exhaust gas absorption pipe 3. At the same time, a control valve is connected to the air pump 15 to prevent air leakage, which should also fall within the protection scope of this application.

[0064] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0065] During material extraction, liquid chemicals flow from the material tank into the liquid flow channel of the inner cylinder through pipes, and are then transported to the reactor via corresponding components. Waste gas from the material tank enters the spherical hood through the gas flow channel, and then enters the integrated tail gas absorption pipe through the spherical hood's openings. This application improves the conveying efficiency of liquid chemicals, increases the flow efficiency of waste gas, and provides excellent sealing. It solves the problem in existing technologies where leakage into the atmosphere during material extraction not only causes serious air pollution but also poses a threat to the ecological environment and human health.
