摘要

The system is used for disposal of rubbish in large building complexes. Use is made of suction pipes and the pipes are connected to traps in floors, for disposal of various types of rubbish and waste material. The air for conveyance of material is not sucked from outside and then discharged to the outside, but carried round in a closed circuit in a horizontal conveyor pipe. This system has the outlet opening joined together with the intake opening and there are considerable reductions in energy wastage.
