The invention relates to the field of electricity and can be used for the production of clean energy by converting energy waste water falling from a height of multi-storey buildings.

The closest to the technical nature of the claimed invention is a device for receiving energy from sewage (EN 84474 U1) including: pipes and generator shaft, the housing, which is installed inside the rotor blades, shaft, output, the end of which is connected to the shaft of the generator, the housing includes an inclined placed the comb and these pipes for sewage.

The disadvantages of the existing devices for energy generation from sewage, is that it does not fully use the energy of falling water, as the blade is only partially overlap the riser pipe, and the curved shape of the blades facilitates the engagement of garbage and as a consequence pollution and stop the generator. No flushing device without opening the case.

The task and the technical result to create a device energy conversion waste water into electrical energy this design, which will allow to increase the operational reliability and stability, rational way of conversion is that the energy moving on the vertical risers of the water into electricity.

The technical result is achieved in that the device energy conversion waste water into electrical energy, includes a vertical flow channel, in the form of a tube with a hydro generator connected to the load at the bottom, in which is located a screw hydro generator with blades, inputs, expansion tank with flush valves, upper and lower air nozzles, which provide, respectively, the flow of the upward air flow, additionally the rotating blades of the screw, and drain, shoulder screws have a tapered cross-section, thus preventing the accumulation in the joints with shaft sediments. The control system allows you to monitor the health of all nodes of the device and redistribute the received power between consumers load and its accumulation.

The invention is illustrated by drawings, where figure 1 shows a diagram of the movement of water and air in the riser pipe, and figure 2 presents the variant of the device energy conversion waste water into electrical energy:

1-trumpet;

2 - upper air outlet;

3 - the flush valve;

4 - hydrogenerator;

5 - expansion capacity;

6 is a bottom air outlet;

8 - battery;

9 - load.

To solve this problem would be optimal reuse of waste water for hot and cold water high-rise buildings. Water (as an example, we will choose the model 22 storey building, having fulfilled its main purpose, which required the cost of electricity paid by consumers, falls from a 60 meters high with a huge kinetic energy spent in idle.

Existing Sewerage systems sewage is provided by a closed gravity pipelines. Sections of the sewer network are laid straight. The change in direction of the sewer piping and connection of the devices is done using the connection details.

Water demand characterizes the optimal amount of water that provides drinking water, sanitation, economic human need in modern comfortable apartment, the basic qualitative characteristics corresponding to the purpose of water as life-support systems. Water demand should be determined by medical specialists in hygiene, however, a formal, systematic national studies on this issue are lacking. On the basis of domestic and foreign who studies water directly from consumers this value is estimated at 50-130 l/person day., when this lower limit corresponds to the minimum landscaping of the home, and the top - optimal (standard). Given the technically required (minimum) water losses, social need accepted at a rate of 140 l/person day.

Considering that in a typical 22-storey building of 6 apartments on each floor in the house received 132 apartments. The average number of residents in a typical apartment will take is equal to 3 people respectively received approximately 396 tenants in the house. By simple calculations, the volume of water consumed by the residents of a typical 22-storey building peer - to-55440 l/person day.

Generated by the electric generator, the electric power management system is supplied to the load or accumulate in the battery. The control system performs the function of monitoring the status of monitorina and redistribution of power to the load.

It should be noted that in normal use the sewers, the possibility of clogging is also not excluded. For work it is necessary that the flow rate has not been below the critical. For sanitation this speed flow in a horizontal pipe should be not less than 0.7 m/s, and filling the cross section of the pipe water is not less than the third diameter. Therefore, the distance between the generators, when creating a cascade of devices energy conversion waste water into electrical energy, ve the vertical riser should take into account this condition.

When sanitation is necessary to apply various technical devices that prevent completely or partially impaired patency of the system and allowing to monitor the condition and cleaning. For this purpose, the pipeline is provided by the so-called "revision" (sealed box) and "clean" (holes in the wall of the pipe, closed tube). They put where the flow of water dramatically changes the character of the movement, for example, to place the annexation of several pipes, sharp turn, inset (a small kink in the riser), and also on the issue.

It should be noted that the configuration of the pipe has a certain impact on the process of two-phase flow (water+air) fluid in a vertical pipeline. In accordance with the terminology hydraulic gas-liquid systems and lowering movement of the two-phase fluid is called "pivotal movement of water in the form of an annular layer moves along the walls of the tower, and inside the flow of water in the form of a rod moving air. The water separates from the wall of the riser and creates resistance of the moving air. Air speed drops, which is accompanied by increasing its static pressure. As a result, the pressure in the riser is higher. In order to prevent clogging of the riser counter flows of water and air on the blades of the screw, air pressure straw is foreseen through the lower air outlet, expansion tank with a screw, where the upward air flow produces work by rotation of the screw, and through the upper air nozzle into the stack.

The device operates as follows: after draining the waste water in the riser pipe (1) is the motion of two-phase liquid - water in the form of an annular layer moves along the walls of the riser down, and inside the flow of water in the form of the rising of the rod moves the air. If water on the blades of the rotor, the hydro generator (4) connected to the shaft with the rotor is driven, i.e. it produces electricity supplied to the control system (7) nakaplivaya on the battery (8), or distributes electricity to the load (9). The rotor blades thicker in mounting the blades to the shaft and is significantly narrower at the tip of the blade, i.e. have a cone-shaped section (4). This form of the blades prevents the accumulation in the joints with shaft sediments and form the shape of the cross section of the pipe riser, allows maximum use of the energy of the falling stream of liquid. The upward flow of air through the lower air pipe (6) comes into the expansion tank (5) and rotates the rotor blades in the opposite direction, and is discharged into the riser through the upper air outlet (2). The expansion tank has the flush valve (3) in case of clogging, the water under pressure is eat clears the rotor blades. The control system allows you to monitor the health of all nodes of the device and redistribute the received power between consumers load and its accumulation.

Device energy conversion waste water into electrical energy, comprising a vertical flow channel in the form of a pipe with a hydro generator connected to the load at the bottom, in which is located a screw hydro generator with blades, characterized in that it additionally introduced expansion tank with flush valves, upper and lower air nozzles, which provide, respectively, the flow of the upward air flow, additionally the rotating blades of the screw, and drain, shoulder screws have a tapered cross-section, thus preventing the accumulation in the joints with the shaft of the sediments, and a control system, nakaplivaya and distributes the received energy.
