The tubular organic membrane 3 is arranged only in the horizontal or vertical separation pipe 1, and is not arranged in the connecting elbow 2. When the organic membrane is polluted by complex components in water during water treatment and separation in the production process of coal-based materials, the flux is reduced, and the separation efficiency is affected. The tubular organic membrane 3 in the separation pipe 1 can be conveniently taken out and replaced, and the separation pipe 1 and the connecting elbow 2 do not need to be replaced as a whole, so that the operation is simple, and maintenance is convenient.

[0025] The outer side of the connecting threaded pipe 4 can be hexagonal in shape, so that the connecting threaded pipe 4 is conveniently disassembled and screwed off, so that the separation pipe 1 and the connecting elbow 2 are separated, and the tubular organic membrane 3 is replaced.

[0026] When the tubular organic membrane 3 is replaced, only the connecting elbow 2 on the same side can be taken off, so that the tubular organic membrane 3 in each separation pipe 1 can be replaced.
