Embodiment Construction
[0037] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0038] A kind of sewage sludge separation method, its concrete steps are:
[0039] (1) Use superheated steam boiler 13 to heat water steam to superheated steam above 500°C; mainly use superheated steam (500°C-700°C), and all processing energy in the treatment process is obtained from superheated steam.
[0040] (2) Spray onto the sludge through the nozzle 12, and the steam ejected from the outlet 19 of the nozzle reaches Mach 2, collides with the sludge in an instant, and the sludge is pulverized into fine particles;
[0041] (3) Instant evaporation and sublimation of water and oil in sludge;
[0042] (4) moisture and oil are separated from solid particles by cyclone separator 4;
[0043] (5) Water and oil are cooled and liquefied by water spraying;
[0044] (6) The liquefied water and oil a...
