[0019] Please refer to Figures 1-3 , this embodiment provides a technical solution: a tail gas purification device for chemical production, including a purification cylinder 1;
[0020] Purification cylinder 1: Ash discharge holes 2 are provided at both the left and right ends of its outer arc surface. A first inclined plate 3 is provided at the left end of the inner arc surface of the purification cylinder 1, and the first inclined plate 3 gradually slopes downward from right to left. A second inclined plate 4 is provided at the right end of the inner arc surface of the purification cylinder 1, and the second inclined plate 4 gradually slopes downward from left to right. The first inclined plate 3 and the second inclined plate 4 are vertically offset. The first inclined plate 3 and the second inclined plate 4 are respectively installed in cooperation with the ash discharge holes 2. A collection cylinder 5 is provided on the outer arc surface of the purification cylinder 1. A circular ring 6 is provided at the upper end of the inner arc surface of the purification cylinder 1. A filter screen 7 is provided on the inner arc surface of the circular ring 6. The filter screen 7 is used to filter the dust particles in the tail gas and purify the tail gas. The dust generated during the purification process will, under the guidance of the first inclined plate 3 and the second inclined plate 4, enter the interior of the collection cylinder 5 through the ash discharge holes 2 for centralized collection of the dust. A guiding inclined ring 8 is provided at the lower end of the inner arc surface of the purification cylinder 1, and the guiding inclined ring 8 gradually slopes downward from right to left. Under the guidance of the guiding inclined ring 8, the dust in the collection cylinder 5 is concentrated towards the ash discharge pipe 9. An ash discharge pipe 9 is provided at the discharge port at the left end of the purification cylinder 1. A plug is inserted into the interior of the ash discharge pipe 9. By simply pulling out the plug inside the ash discharge pipe 9, the dust inside the tail gas purification device can be cleaned. Guide posts 10 are vertically slidably connected to the guide holes on the surface of the circular ring 6. Connection rings 11 are provided between the ends of the guide posts 10. A horizontal plate is provided in the middle of the lower connection ring 11. Convex columns 13 are respectively provided on the upper surface of the horizontal plate. By sliding the guide posts 10 in the guide holes on the surface of the circular ring 6, the lower connection ring 11 drives the convex columns 13 to move up and down, knocking on the surface of the filter screen 7 to make the dust accumulated on the surface of the filter screen 7 fall downward. Spring sleeves 12 are movably sleeved on the outer arc surfaces of the guide posts 10. The upper ends of the spring sleeves 12 are fixedly connected to the circular ring 6, and the lower ends of the spring sleeves 12 are fixedly connected to the lower connection ring 11, making the up and down reciprocating movement of the guide posts 10 more stable. It also includes a vibration motor 14, which is arranged on the surface of the upper connection ring 11. The input end of the vibration motor 14 is electrically connected to the output end of an external control switch, providing power for the up and down reciprocating movement of the guide posts 10. A tail gas outlet pipe 15 is provided at the exhaust port at the upper end of the purification cylinder 1, and a tail gas inlet pipe 16 is provided at the air inlet at the lower end of the purification cylinder 1, facilitating the entry and exit of the tail gas from the interior of the purification cylinder 1.
[0021] The working principle of an exhaust gas purification device for chemical production provided by the utility model is as follows: During the chemical production process, the exhaust gas generated in the production process enters the purification cylinder 1 through the exhaust gas inlet pipe 16. During the upward flow of the exhaust gas inside the purification cylinder 1, the dust particles in the exhaust gas are filtered by the filter net 7 to purify the exhaust gas. The purified exhaust gas is discharged from the exhaust gas outlet pipe 15. During the exhaust gas purification process, the vibration motor 14 is started by using an external control switch. The vibration motor 14 drives the upper connecting ring 11 to move up and down, causing the guide post 10 to slide in the guide hole on the surface of the circular ring 6, overcoming the elastic force of the spring 12, so that the convex post 13 moves up and down reciprocally to strike the surface of the filter net 7, causing the dust accumulated on the surface of the filter net 7 to fall downward. During the falling process of the dust, under the guidance of the first inclined plate 3 and the second inclined plate 4, the dust enters the collection cylinder 5 through the ash outlet hole 2. At the same time, under the guidance of the guiding inclined ring 8, the dust in the collection cylinder 5 is concentrated towards the ash outlet pipe 9. Just pull out the plug inside the ash outlet pipe 9 to clean the dust inside the exhaust gas purification device.
[0022] It should be noted that the vibration motor 14 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended to select a vibration motor of model 1027. The external control switch is provided with a switch button corresponding to the vibration motor 14 for controlling its switch operation.
