Half-dead-end filter

The invention discloses a half-dead-end filter which includes a membrane shell (101) and a filter core (102). The filter core (102) is sealed and fixed inside the membrane shell (101) via sealing rings (103) arranged on two ends of the filter core (102). A material inlet (105) is arranged on one end of the membrane shell (101). A material outlet (106) is arranged on the other end of the membrane shell (101). A membrane element of the filter core (102) has a porous structure, wherein pore channels include water inlet pore channels and water outlet pore channels, of which one ends are opened while the other ends are closed. The openings of the water inlet pore channels are communicated with the material inlet (105). The openings of the water outlet pore channels are communicated with the material outlet (106). The two adjacent water inlet pore channels are separated via one or more water outlet pore channels. The filter is small in occupied area and has extensive application range, highprocessing efficiency and
