[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figures 1 to 6 As shown, an embodiment of the present invention provides an exhaust gas absorption and treatment device, specifically comprising a storage box 1, on which is mounted a treatment mechanism 2. The treatment mechanism 2 includes an air inlet pipe 201. The air inlet pipe 201 is mounted at one end of the storage box 1, and one end of the air inlet pipe 201 extends into the interior of the storage box 1. An exhaust pipe 202 is mounted at the other end of the storage box 1. A plurality of equally spaced fixed pipes 205 are vertically connected to the bottom of one end of the air inlet pipe 201. The bottoms of the plurality of fixed pipes 205 are respectively connected to connecting pipes 206. The sidewalls of the plurality of connecting pipes 206 are provided with a plurality of exhaust holes 208. A plug 209 is mounted within the connecting pipe 206, which is slidably connected to the interior of the connecting pipe 206 via a compression spring 210. A feed pipe 204 is connected to the top of the storage box 1.
[0027] See also Figures 1 to 6As shown, the tops of multiple connecting tubes 206 are threadedly connected to the bottoms of multiple fixed tubes 205. The diameter of connecting tubes 206 is smaller than that of fixed tubes 205, which facilitates disassembly and maintenance of connecting tubes 206 and allows gas to accumulate and be discharged within connecting tubes 206. A drive rod 211 is vertically connected to the bottom of the plug 209. Drive rod 211 extends through compression spring 210 to the outside of the bottom of connecting tubes 206. Drive rod 211 is slidably connected to the bottom of connecting tubes 206. A push plate 207 is mounted on the bottom of drive rod 211. The installation of drive rod 211 facilitates the installation of push plate 207, and the movement of push plate 207 promotes the stirring of lime water.
[0028] See also Figures 1 to 6 As shown, a delivery pipe 203 is provided at the center of the top of the storage box 1. One end of the delivery pipe 203 is connected to the exhaust pipe 202. This allows the gas inside the storage box 1 to be better discharged and prevents the gas from accumulating inside the storage box 1. The bottom of the delivery pipe 203 is a "concave"-shaped structure, and the connection between the delivery pipe 203 and the storage box 1 is a funnel-shaped structure, which facilitates a good connection between the delivery pipe 203 and the exhaust pipe 202 and allows the gas at the top of the storage box 1 to be smoothly discharged. The bottom of the storage box 1 has a conical structure, and the bottom side of the storage box 1 has an arc-shaped structure, which helps to concentrate the lime water at the bottom of the storage box 1 and allows the sediment to accumulate at the bottom of the storage box 1.
[0029] Specifically in this embodiment, the storage box 1 is first fixed, and then the air intake pipe 201 is connected to the external exhaust pipe, and lime water is added to the storage box 1 through the feed pipe 204, so that the lime water floods the multiple connecting pipes 206, and the external exhaust gas enters the multiple connecting pipes 206 through the air intake pipe 201 and the multiple fixed pipes 205. With the cooperation of the compression spring 210, the leather plug 209 is pressed against the exhaust hole 208, so that the lime water does not enter and flow back. When the exhaust gas is discharged, when the air pressure reaches a certain pressure, the leather plug 209 is freed from the elastic force of the compression spring 210 and contracts, so that the exhaust hole 208 is opened, so that the exhaust gas is mixed with the lime water, thereby neutralizing the acidic substances in the exhaust gas. At the same time, the leather plug 209 drives the driving rod 211 to push the push plate 207 in the lime water. When the gas is discharged, the pressure decreases, the leather plug 209 is reset, and the push plate 207 is reset. The swing of the push plate 207 plays a role in stirring the lime water, preventing the lime water from settling and affecting the neutralization effect.
[0030] See also Figures 1 to 6As shown, a cleaning mechanism 3 is mounted at the bottom of the storage box 1. The cleaning mechanism 3 includes a collection tube 301, which is threadedly connected to one end of the bottom of the storage box 1. A push block 305 is slidably connected to the inside of the bottom of the storage box 1. One end of the push block 305 is connected to a pull rod 303, which extends to the outside of the storage box 1. The pull rod 303 is slidably connected to the storage box 1. The installation of the collection tube 301 facilitates the storage of sediment. The cooperation between the pull rod 303 and the push block 305 enables the removal of debris deposited at the bottom of the storage box 1. A sealing ring 302 is mounted at the bottom of the storage box 1. The pull rod 303 is slidably connected to the sealing ring 302. The installation of the sealing ring 302 ensures a good seal between the pull rod 303 and the storage box 1, preventing limewater from overflowing.
[0031] To further optimize this embodiment, a truncated cone-shaped pull tab 304 is mounted on one end of the pull rod 303. This allows for easy and slip-resistant operation of the pull rod 303. A connecting plate 306 is mounted on one end of the collection tube 301. The sidewall of the connecting plate 306 is provided with a plurality of annular grooves 307. The cooperation between the connecting plate 306 and the grooves 307 facilitates rotational control of the collection tube 301 and prevents slipping.
[0032] Specifically in this embodiment, by driving the pull rod 303, the pull rod 303 drives the push block 305 to push the debris settled at the bottom of the storage box 1, and the debris enters the collection tube 301 for storage. When a certain amount is stored, one end of the collection tube 301 is blocked by the push block 305, and then the collection tube 301 is taken out for cleaning. At the same time, the lime water inside the storage box 1 can be discharged and cleaned by moving the push block 305.
