Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A lower movable plate fiber filter is shown in figures 2 and 3 and comprises a tank body 13, a fiber bundle filtering assembly and a gas distributor 16, wherein the fiber bundle filtering assembly and the gas distributor are installed in the tank body, the fiber bundle filtering assembly comprises an upper fixed orifice plate 12, a lower movable orifice plate 14 and a fiber bundle 20, the upper fixed orifice plate is fixed in the tank body through four fixed pipes 11 which are uniformly arranged, the top ends of the four fixed pipes are welded with the inner wall of the top of the tank body, the bottom ends of the four fixed pipes are welded with the top surface of the upper fixed orifice plate, the fiber bundle is uniformly hung between the upper fixed orifice plate and the lower movable orifice plate, and the lower movable orifice plate is not fixed and is.
A circle of supporting plate 15 is arranged below the lower movable pore plate around the inner wall of the tank body, so that the lower movable pore plate is prevented from accidentally falling.
The structure of the gas distributor is the prior art and will not be described here.
