Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing.
[0024] As shown in the figure, the outer cylinder 10 in the present invention is a fixed sealed hollow cylinder, the inner cylinder 9 is coaxial with the outer cylinder, and micro-channels of different sizes are distributed on the wall, the aperture is 0.01-1.0 mm, and the porosity 50% to 80%, the spiral blade 11 is fixed on the outer wall of the inner cylinder, leaving a small gap with the outer cylinder, similar to the structure of the blower wheel and the outer wall, the inner cylinder is fixedly connected with the transmission shaft 5 through the connecting rod 4, Driven by the drive shaft, the inner cylinder and the screw blades rotate together. The raw material gas enters the cavity 2 between the outer cylinder and the inner cylinder through the raw material gas inlet 7, and goes out from the raw material gas pipeline 1 and directly enters the electric stack 13. The ...
