Abstract

SOLAR ELECTRICAL AND DESALINIZING PLANT AND WASTE TRACTOR. Comprised of three systems, one for desalination (solar distillation), one for electrical production, and one for sewage treatment, which can work individually or in combination, the principle of operation is the concentration of solar energy through mirrors (1) over a metal (2) that conducts heat and boils water from a reservoir (4a and 4b). The demineralized water vapor produced by the enclosed electrical generation system is conducted directly through a thermal pipe (6) to a steam turbine or locomotive (10), which coupled to a generator (11) produces electricity, and is condensed by passing through the supply channel (7) through a coil or laminar housing (8), returning the water to the demineralised water boiling reservoir (4a). The salt water vapor produced by the desalination system is condensed in the same way or with the aid of sprinklers (12), and the resulting water is reserved for consumption with salt as a byproduct. The sewage treatment is done by its simple cooking, generating as byproducts the fertilizer and the methane gas.

Description

"SOLAR ELECTRICAL AND DESALINIZER AND WASTE TRACTOR"

The present utility model patent relates to equipment which may have domestic or industrial use, having as its working principle the concentration of solar energy through mirrors, causing the boiling of an aqueous solution in a reservoir. The steam resulting from boiling demineralized water passes through a steam turbine, which coupled to a generator, produces electricity, and is cooled through the supply channel before returning to the boiling reservoir. The steam resulting from the boiling of saline water is condensed through the supply channel and the generated water is reserved for consumption with salt as a byproduct. And to treat the sewage just boil it and it will become sterilized, having as a byproduct organic fertilizer and methane gas that can be channeled.

The current state of solar energy utilization techniques for desalination, which involves distillation, electrodialysis and reverse osmosis, and for energy production, which goes through solar ovens, steam engines and photovoltaic energy, is represented in the utility model. of my own, filed as a patent application under number MU8500293-3, and which is being refined with the present recast of the invention with the sewage treatment part.

The improvements consist of using a sewage system to be boiled in a reservoir, from which it will be disinfected and ready to be used as fertilizer, generating methane gas that can be piped and stored for use. Another enhancement is the possibility of using flat mirrors instead of concave ones, as they are cheaper.

A desalination and sewage treatment solar power plant can contain several mirrors and turbines and its capacity for desalinated water production, energy and sewage treatment varies according to the size of the structures and the thermal conductivity of the materials involved in the thermodynamic processes, the systems being sized according to local or regional water and energy demands.

It is noteworthy that the systems can also work separately, in the case of direct use of seawater to cool the generated steam, and that the desalination plant will have salt as a byproduct. The following figures are only schematic drawings given by way of example. limiting.

Figure 1 shows the plan view of the general arrangement of the invention.

Figure 2 shows the cross section of the invention.

The replacement of the minimum quantities of mineral salts, recommended for human consumption, in the final water must be calculated and this increase can be done through sprinklers, introducing the supply water itself, after filtering and proper treatment, along the condenser. that would still accelerate condensation.

This equipment may consist of one or more reflectors (1) which may be concave (parabolic or semi-cylindrical) or flat and have external or submerged heat transmission rods (2) and their operation and dimensions may be They are adjusted for maximum efficiency by programming the mirror through a heliostat to monitor the movement of the sun during the day.

After reflection and concentration of solar energy, through a glass (13), directly on a submerged conductive metal plate (2), it will transmit the heat to the water, or, in the case of an external rod, passing it through a low conductivity material (3) which will permit the sealing and / or installation of a safety valve between the wall or slab of the boiling reservoirs (4a and 4b).

The conducting plates must be technically sized to maintain a certain design pressure in the boiling reservoirs (4a and 4b) and the level of the saline boiling reservoir (4b) is regulated by a metal float or sensor integrated with an injector. (5), installed in the piping (6) coming from the supply channel (7).

The different vapors produced in the systems are condensed by passing through the supply channel (7) inside a condensing coil or laminar box (8). In the case of the electric generation system, demineralized water returns to the demineralized water boiling reservoir (4a), and in the desalination system, a salt sprinkler system (12) may be introduced along the condenser (8). ), ending in the final water reservoir (9) which may have the sloping roof to facilitate concentration of the remaining steam and dripping of the possible formed droplets.

To generate power, it is sufficient to channel the steam from the electrical generation system through a thermal pipe (6) directly to a steam turbine or locomotive (10), and attach them to the generator (11), and then pass through the condenser (8). ) and return the resulting water to the demineralized water boiling reservoir (4a).

To treat the sewage just bring it to boiling and channel the gases produced.

The reservoir structures (4a and 4b), (7) and (9) may be of various shapes and be constructed of case-specific reinforced concrete and the coil or condensing laminar housing (8) may be constructed of metal. or reinforced concrete, with due technical dimensioning according to its dimensions and required thermal conductivity.
