AI Technical Summary
The existing plastic waste gas filtration device has low filtration effect and cannot effectively remove particles in the waste gas.
A plastic waste gas filter device is designed. By setting a mist pipe in the filter box, the atomized flocculant is transferred to the inner cavity of the filter box, increasing the contact surface between the waste gas and the flocculant, and promoting particle aggregation. At the same time, a crushing plate is installed in the condensing box to crush the exhaust gas bubbles to further improve the filtration effect.
By increasing the contact surface between the waste gas and the flocculant and crushing the waste gas bubbles, the screening effect of the filter is significantly improved and the efficiency of waste gas filtration is enhanced.

[0025] A mounting block is installed on the inner wall of the flocculation box 4, and an atomizing sheet 14 is installed on the upper end of the mounting block. The mist delivery pipe 11 is connected to the inner cavity of the filter box 1, and the atomizing sheet 14 is close to the mist delivery pipe 11, so that the atomizing sheet 14 can atomize the flocculant in the flocculation box 4 and transfer it to the mist delivery pipe 11.
[0026] The upper end of the filter box 1 is threadedly connected with a side door via bolts. The side door, the side wall of the filter box 1 and the side wall of the filter screen 2 are all provided with threaded holes. The threaded holes are threadedly connected with the bolts to facilitate opening the side door to remove the particles screened at the filter screen 2.
[0027] A limit ring 10 is installed at one end of the transmission shaft 7 extending into the flocculant box 4. The rotating disk 9 rotatably connects the transmission shaft 7 and the exhaust pipe 12, and the rotating disk 9 is slidably connected to the limit ring 10, which facilitates the air pipe 8 to transfer the exhaust gas to the inner cavity of the rotating disk 9 and avoids affecting the rotation of the transmission shaft 7 and the exhaust pipe 12.
