<P>PROBLEM TO BE SOLVED: To utilize sewage that is generated from a high-rise building or a super-high tower, for power generation since, when attention is paid to fall energy of the sewage, there is no recycle plan for the sewage at present and the sewage only uselessly flows into an underground sewer. <P>SOLUTION: Sewers of a high-rise building can be roughly separated into two kinds of a sewer for each floor and a main sewer in which the sewage of all the floors from the rooftop to the underground flow. In the high-rise building, there are installed a floor power generator which performs small power generation for each floor and a main power generator which utilizes the sewage flowing down in the main sewer of the whole. Practical power is secured from useless sewage and 50% or more in power used for the high-rise building can be generated independently, thereby dealing with the lack of electric power. In the floor power generator, power is generated by a screw type hydraulic turbine and in the main sewer, power is generated and obtained by a propeller hydraulic turbine type power generator which is capable of also dealing with dirt in sewage. <P>COPYRIGHT: (C)2013,JPO&INPIT |
