DETAILED DESCRIPTION

[0028] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] Example 1

[0030] A tail gas treatment device for preparing lithium carbonate from lepidolite, such as Figure 1-Figure 11 As shown, it includes a liquid storage frame 1, a liquid spray frame 2 is connected to the top of the liquid storage frame 1, a water pump 4 is connected to the right side of the liquid storage frame 1, a water pipe 3 is connected between the water pump 4 and the liquid spray frame 2, a nozzle 5 is connected to the upper end of the water pipe 3, and the nozzle 5 is located inside the liquid spray frame 2. Three mounting heads 6 are connected to the top of the liquid storage frame 1 and the bottom of the liquid spray frame 2, and a first downpipe 7 and a second downpipe 8 are clamped between the upper and lower corresponding mounting heads 6. A liquid spray mechanism is arranged on the liquid spray frame 2, and the liquid spray mechanism is used to adjust the flow state of water in the liquid spray frame 2. A connecting mechanism 10 is arranged on the mounting head 6, and the connecting mechanism 10 is used for quick-disconnection installation of the first downpipe 7 and the second downpipe 8.

[0031] It should be noted that, first, the first downcomer 7 and the second downcomer 8 are quickly installed by relying on the connecting mechanism 10. During operation, the liquid storage frame 1 is filled with liquid (such as water or other absorbents) for absorbing and treating harmful substances in the exhaust gas. The water pump 4 extracts the liquid from the liquid storage frame 1 and transports it to the nozzle 5 located inside the liquid spray frame 2 through the water pipe 3. When the liquid reaches the nozzle 5, it is evenly sprayed into the internal space of the liquid spray frame 2. As the exhaust gas moves, the exhaust gas will begin to move upward through the first downcomer 7 and the second downcomer 8. At this time, the flow state of the water flow in the liquid spray frame 2 is adjusted by relying on the liquid spray mechanism, so that the liquid flows slowly along the inner walls of the first downcomer 7 and the second downcomer 8, and contacts the rising exhaust gas in the reverse direction. In this process, the harmful components in the exhaust gas (such as acidic gases, heavy metals, etc.) will react chemically or physically adsorb with the liquid, thereby being removed, and the purified exhaust gas will continue to rise and be discharged through the discharge port.

[0032] The liquid discharge mechanism 9 includes a lifting rod 91, which is slidably and rotatably connected to the liquid spray frame 2. The lifting rod 91 is used to adjust and block the water outlet at the bottom of the liquid spray frame 2. A mounting plate 92 is rotatably connected between the tops of the lifting rods 91. A hydraulic cylinder 93 is installed on the upper part of the liquid spray frame 2. The telescopic end of the hydraulic cylinder 93 is connected to the middle part of the mounting plate 92. A drive motor 94 is installed on the mounting plate 92. The output shaft of the drive motor 94 is connected to the lifting rod 91 in the middle. A synchronization component 95 is connected between the lifting rods 91. A limit seat 96 is installed on the upper front side of the liquid spray frame 2. The limit seat 96 is used to limit and block the mounting plate 92.

[0033] It should be noted that the hydraulic cylinder 93 serves as a power source, and its telescopic end is connected to the middle part of the mounting plate 92. When it is necessary to adjust the water outlet at the lower part of the spray frame 2, the hydraulic cylinder 93 is actuated to lift or lower the position of the mounting plate 92 by extending or shortening its telescopic end. Since the mounting plate 92 is rotatably connected between the tops of the lifting and lowering rods 91, as the mounting plate 92 moves up and down, the lifting and lowering rods 91 also slide accordingly. At the same time, a driving motor 94 is installed on the mounting plate 92, and its output shaft is connected to the lifting and lowering rod 91 in the middle. When the driving motor 94 is started, it will drive the lifting and lowering rod 91 directly connected thereto to rotate, and the synchronization component 95 ensures that all the lifting and lowering rods 91 can rotate in a coordinated manner, thereby ensuring the consistency and stability of the entire device action. In this way, the water outlet at the lower part of the spray frame 2 can be accurately adjusted and blocked by the rotation of the lifting and lowering rods 91 to control the direction and flow rate of the liquid outflow.

[0034] The connecting mechanism 10 includes a fixing ring 102, and the mounting head 6 is provided with a fixing ring 102, and the fixing ring 102 is connected to a spring 103, and the end of the spring 103 is connected to a connecting pipe 101, and the connecting pipe 101 is used to clamp and assemble the first downcomer pipe 7 and the second downcomer pipe 8.

[0035] It should be noted that the connecting mechanism 10 is designed for quick installation and removal of the first down pipe 7 and the second down pipe 8 to ensure the convenience of maintenance and cleaning work. A fixing ring 102 is provided on each mounting head 6, which provides a stable base for the entire connecting mechanism 10. A spring 103 is connected to the fixing ring 102. The design of the spring 103 allows the connecting pipe 101 to have a certain range of motion and provides the necessary elastic restoring force. When the first down pipe 7 or the second down pipe 8 needs to be installed in place, the operator only needs to align one end of the down pipe with the connecting pipe 101 and apply appropriate pressure. Under the action of pressure, the spring 103 is compressed, so that the connecting pipe 101 can temporarily make room for the down pipe to be smoothly inserted. Once the first down pipe 7 and the second down pipe 8 reach the correct position, the spring 103 will return to its original state, pushing the connecting pipe 101 close to the outer wall of the down pipe, achieving safe and reliable clamping. This not only ensures good sealing, but also due to the presence of spring 103, can adapt to dimensional changes within a certain range, thereby increasing the compatibility and stability of the system. When the sewer pipe needs to be removed, the operator can manually press the connecting pipe 101 to separate from the first sewer pipe 7 and the second sewer pipe 8. At this time, the spring 103 plays an auxiliary role again, helping the connecting pipe 101 to quickly reset and prepare for the next connection.

[0036] Example 2

[0037] It also includes a dehumidification mechanism 11, which includes a dehumidification chamber 111. The dehumidification chamber 111 is connected to the right side of the spray frame 2, and a cover plate 112 is clamped on the top of the dehumidification chamber 111. A blocking screen frame 113 is slidably connected to the right side of the dehumidification chamber 111. The blocking screen frame 113 is used to place the adsorption material, and the blocking screen frame 113 and the dehumidification chamber 111 are a detachable connection structure.

[0038] It should be noted that when the exhaust gas that has undergone preliminary treatment enters the dehumidification chamber 111 from the right side of the spray frame 2, it will first contact the blocking screen frame 113 located on the right side of the dehumidification chamber 111. Adsorption materials (such as silica gel, activated carbon or other desiccant) are placed in the blocking screen frame 113. These materials have strong water absorption properties and can effectively absorb moisture and other possible pollutants carried in the exhaust gas. The blocking screen frame 113 and the dehumidification chamber 111 are connected by a sliding connection and have a detachable structure. The blocking screen frame 113 can be easily removed from the dehumidification chamber 111 when needed, which is convenient for regular replacement or regeneration of the adsorption material, thereby ensuring the continuity and reliability of the dehumidification effect. At the same time, the detachable connection also facilitates the cleaning and maintenance of the blocking screen frame 113 and the interior of the dehumidification chamber 111.

[0039] The pressing mechanism 12 also includes a pressing mechanism 12, which includes a fixing seat 122. Three fixing seats 122 are connected to the upper rear side of the liquid storage frame 1. Holes are drilled on the fixing seats 122 to connect connecting rods 123. The front sides of the connecting rods 123 are rotatably connected to first connecting members 121. The first connecting members 121 are connected to adjacent connecting pipes 101. Three guide rods 124 are connected between the liquid storage frame 1 and the rear of the liquid spraying frame 2. Lifting frames 125 are slidably connected to the guide rods 124. The bottoms of the lifting frames 125 are rotatably connected to adjacent connecting rods 123. The upper front sides of the lifting frames 125 are connected to connecting frames 127. The front sides of the connecting frames 127 are connected to second connecting members 126. The second connecting members 126 are connected to adjacent connecting pipes 101.

[0040] It should be noted that three fixing seats 122 are connected to the upper side of the rear portion of the liquid storage frame 1. Holes are drilled on each fixing seat 122 and connecting rods 123 are connected through the holes. These connecting rods 123 are responsible for transmitting force. The front side of the connecting rod 123 is rotatably connected to a first connecting member 121. These first connecting members 121 are respectively connected to adjacent connecting pipes 101, ensuring that when the connecting rod 123 moves, the adjacent connecting pipes 101 can be driven to move synchronously through the first connecting member 121. When working, the operator can directly Then, the connecting pipe fitting 101 on the lower side is pressed down. At this time, the force will act on the adjacent connecting rod 123, causing the connecting rod 123 to rotate. As the connecting rod 123 rotates, the lifting frame 125 will slide down along the guide rod 124. As the lifting frame 125 descends, it will act on the connecting pipe fitting 101 on the upper side again through the connecting frame 127 and the second connecting piece 126, further ensuring the consistency of the movements of all the connecting pipe fittings 101, and then quickly removing the first downcomer pipe 7 and the second downcomer pipe 8, thereby improving the disassembly and assembly efficiency.

[0041] The anti-splash mechanism 13 is also included, and the anti-splash mechanism 13 includes an anti-splash cover 131. The anti-splash cover 131 is connected to the right side of the liquid spray frame 2. The anti-splash cover 131 is provided with a liquid outlet 132, and the liquid outlet 132 is used to guide the liquid accidentally splashed to the smoke exhaust port back to the liquid spray frame 2.

[0042] The liquid storage frame 1 further includes an air intake mechanism 14 , which includes an air intake pipe 141 . The air intake pipe 141 is disposed in the liquid storage frame 1 , and three air outlets 142 are disposed on the air intake pipe 141 .

[0043] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention.
