Anti-corrosion air pipe structure in kiln tail dust collection chamber

The utility model discloses an anti-corrosion air pipe structure in a kiln tail dust collection chamber, which comprises a shell, the right side wall of the shell is communicated with a transmission pipe, and a fan is fixedly connected inside the outlet of the transmission pipe. By arranging the filtering and recycling mechanism, dust can sequentially pass through the biological nano-membrane and the filter screen curtain after entering the shell, the biological nano-membrane can adsorb dust in tail gas to the surface to enable the dust to be clustered and then automatically break away from the surface of the biological nano-membrane, and a semiconductor chilling plate can reduce clean water in the water tank to a low-temperature state; then, a submersible pump conveys clean water into a water inlet pipe, a filter screen curtain is sprayed through a spraying head, so that the filter screen curtain is in a water curtain state, dust in tail gas is conveniently captured, and then waste water falls into a separat
