The upper ends of the first washing liquid pipeline 9 and the second washing liquid pipeline 10 both extend out of the industrial waste gas cleaning tower 1.

[0030] The waste gas treatment device includes a magnetic pump 4, which is arranged on the outside of the industrial waste gas cleaning tower 1. The input end of the magnetic pump 4 is fixedly connected to a washing liquid input pipe 5, and the output end of the magnetic pump 4 is fixedly connected to a washing liquid output pipe 6. The washing liquid input pipe 5 is fixedly connected to the surface of the industrial waste gas cleaning tower 1, and the washing liquid input pipe 5 is connected to the interior of the industrial waste gas cleaning tower 1.
