[0027] The working principle and usage process of this utility model are as follows: Firstly, during operation, the waste gas generated during the polymer photovoltaic frame fabrication process is input into the spray tower 1 through the waste gas inlet 2.

Water mist is then sprayed from the five nozzles 11 at the bottom of the spray pipe 10, thereby filtering the waste gas. The relatively clean waste gas after filtration by the spray tower 1 is then transported to the waste gas filtration chamber 14 via the gas supply pipe 4.
