Rainwater and sewage gravity potential energy collecting device

Abstract

The invention provides a rainwater and sewage gravity potential energy collecting device. The rainwater and sewage gravity potential energy collecting device comprises a water turbine, a roof drainagepipe, a second-floor drainage pipe and a first-floor drainage pipe, wherein the water turbine main shaft, the roof drainage pipe, the second-floor drainage pipe and the first-floor drainage pipe sequentially sleeve from inside to outside by taking the central axis of the water turbine main shaft as the center, a water turbine is sequentially provided with an upper impeller, a middle impeller anda lower impeller from top to bottom along the main shaft, and the distances of the positions of the highest points of the upper impeller, the middle impeller and the lower impeller lower than the bottom surfaces of an upper middle floor drain pipe and a lower middle floor drain pipe are 10-20 mm, the central axis of a sewage diversion pipe in one building is located on the same horizontal plane with the intersection point of the outer wall of the drainage pipe of the building and the highest point of the middle impeller, and the central axis of a second-floor sewage flow guide pipe is locatedon the same horizontal plane with the intersection point of the outer wall of the second-floor drainage pipe and the highest point of the upper impeller. Scattered distribution is collected in the rural and town energy-saving emission reduction resource recycling field, the gravity potential energy of the rain sewage and the small-power distributed energy station can be continuously discharged, and the device can be used. The rainwater and sewage gravity potential energy collecting device is little in investment, convenient to install, and compact in arrangement, and the converting efficiencyfrom the gravity potential energy to the rotating energy is 75%.

Description

technical field [0001] The invention belongs to the field of recycling and comprehensive utilization of energy-saving and emission-reducing resources in rural towns, and in particular relates to a rainwater and sewage gravity potential energy collection device suitable for efficiently converting rainwater and sewage gravity potential energy into rotational kinetic energy. Background technique [0002] National energy conservation and emission reduction, resource recycling and low-carbon life have become a subject of concern. [0003] A lot of rainwater sewage is usually collected and directly discharged into the sewage pipes. The sewage first flows into the vertical pipes, and then flows into the horizontal sewage pipes for discharge. When sewage falls from a high place, it contains abundant potential energy. Sewage enters from the upper end of the sewage pipe and accelerates down to the bottom. There is a lot of kinetic energy, but it is not further utilized in the current...
