The invention is herein described, by way of example only, with reference to the accompanying drawings, wherein:
The principles and operation of a solid/liquid separating generating system according to the present invention may be better understood with reference to the drawings and the accompanying description.
Referring now to the drawings,
An option is a non-stick inner surface to the cupped blades, such as Teflon, that prevents the solids from sticking to the turbine. Ideally, the turbine will be a slow rpm, high-torque machine. The method of adjusting the speed of revolution of the turbine to the nature of the solids is included.
In summary, the steps are: (1) separation of solids from liquids by at least one rotating turbine, (2) separate solid and liquid receptacles, (3) optional repetition of the process operating from the receptacles.
Another option is control of the outflow to work with the speed of the turbine and the nature of the mixture. For example, a thicker mixture would require a slower revolution.
The low-revolution shaft would ideally be attached to an adjustable gear, whether automatically adjustable or replaceable, that can accommodate changes in revolution speed easily. In particular, a gear that increases the rpm will enable a choice of higher rpm generators.
It is a given that this system will attach to a generator or other method of transferring the mechanical energy of rotation into another form of usable energy.
While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications and other applications of the invention may be made.
The present invention successfully addresses the shortcomings of the presently known configurations by providing a system and method to separate solids and liquids.
It is now disclosed for the first time a system for separating a mixture of liquids and solids, comprising:
In one embodiment, the system further comprises
According to another embodiment, the axis of the turbine is at a lower elevation than the outlet.
According to another embodiment, the mixture is sewage.
According to another embodiment, the revolutions per minute (rpm) of the central shaft are less than 30 per minute.
According to another embodiment, the revolutions per minute (rpm) of the central shaft are less than 10 per minute.
In one embodiment, the system further comprises:
In one embodiment, the system further comprises:
According to another embodiment, the blades have a non-stick coating.
In one embodiment, the system further comprises:
According to another embodiment, the gear increases the rpm. According to another embodiment, the turbine's shaft is attached directly to a generator.
In one embodiment, the system further comprises:
It is now disclosed for the first time a method of at least partially separating solids and liquids by means of a turbine.
According to another embodiment, the solid/liquid mixture is sewage.
According to another embodiment, the turbine blades comprise a filter.
According to another embodiment, the turbine has an rpm of less than 30.
According to another embodiment, the turbine's shaft is attached to an adjustable gear and then optionally to a generator.
According to another embodiment, the turbine's shaft is attached directly to a generator.
It is now disclosed for the first time a method of adapting the characteristics of a solid/liquid separating turbine system to the thickness of the mixture so that so that at least 10% of the liquid is separated with each revolution.
According to another embodiment, the result is obtained by adjusting the rpm of the turbine.
This patent application claims the benefit of U.S. Provisional Patent Application No. 61/037,011, entitled Provisional 3-08 Slanted roof wind turbine Sewage turbine system and buoys, filed Mar. 17, 2008. The present invention relates to a device and method for separating liquids from solids while simultaneously producing electricity. This is of particular value in sewage treatment, where recovery of water is of increasing importance.
