Abstract

The energy accumulator is a highly insulated container to maintain a very high temperature of the molten material that we have deposited in it and this is achieved by transforming all the electrical energy produced by the various types of generation of surplus electric current and that can not have access to it. The network, transforming that surplus into heat, by means of an electric arc or resistances, until it fuses it. Later through a heat exchanger, we transform it again into electrical energy, when there is demand for it or we distribute it directly as heat for massive heating or industrial uses. We can also reach the melting point, receiving the sun's rays that we would deviate from solar towers or specific solar plants, following the same procedure.

Description

Energy accumulator

The big problem that has always been raised in the production of electrical energy is the discontinuity in its production, then on the one hand when the network does not need energy, this, has to be reduced or interrupted, or when the sources, if these are natural, do not provide enough energy for the system to work or, for providing much higher energy than required, and the system does not support it.

In a word, with the dead times, in the that we must stop producing, because the network does not require it, because lack in the source or due to excess energy provided by this and the network does not admit it, the actual production of electric power looks tremendously diminished with respect to what would have occurred without these interruptions, seeing how it is lost without possible Recovery. This is when the system is missing to save it, cover dead times and take advantage of surplus of it.

This is precisely my invention, which covers totally all these needs, giving the possibility of make the most of the sources that supply us with energy, transform it and then take it out when necessary covering this way all the dead times, taking advantage of the excesses of production that could have been produced.

The system is very simple, the electrical energy produced through our sources, we then transform it into heat, but at a very high temperature, making it can be transmitted to materials that have a very high degree of fusion. Already reached this point, these materials housed in a highly insulated container, can maintain a very high temperature, more than enough time to cover any lack of supply however long it may be and through a heat exchanger, when we need it, we would produce the steam necessary to move a turbine that generates energy through an alternator when the network requires it, or we can also distribute this heat directly for the massive supply of heating and hot water
etc.

Transforming initial energy into heat to very high temperature, has the advantage that with good insulation the keeps operating for much longer allowing cover any eventuality Yes, this process has losses, but they are compensated with a new energy production than before it was impossible.

Process

For this process, we will have a container or accumulator, large enough to meet the needs that they have. This container or accumulator will be perfectly insulated to maintain a very high temperature and for a long time time, there are systems good enough not to have Than make a description of him. In this container we will install a heat generator, such as a voltage arc or resistors high performance to generate high temperature heat capable of melting any material that we put. On the one hand, the arch voltaic or resistors, through the primary electric current that we have generated, will produce enough heat, so that it can melt this material that we have deposited, and the heat coming of this merger, it will be stored for use through a heat exchanger, when needed, producing steam from enough water to move a turbine and this, in turn a alternator that will generate electric current when consumption is require. The maintenance of this molten material, allows to cover without problems the faults that our source may have or cover also the excess energy that we can supply and we cannot admit, this heat accumulator is the ideal mattress for not waste any energy that comes to us and eliminate the peaks of the system.

We can use this same procedure to take advantage of the solar energy source that is now lost, it is that is, the heat source from which the accumulator is powered, in instead of coming from a voltaic arc or similar, it could come from the solar energy, for example, from solar towers (Figs. 3 and 4), already that in the solar towers, these receive the sun's rays through of some primary mirrors concentrating on it to take advantage of the heat as a source of energy and my proposal, is that mentioned solar rays hit a secondary mirror, simple or compound that would reflect and concentrate them on my energy store, entering through a gap left for this purpose and affecting the high temperature flux material, which is deposited in the accumulator. With my system we have an advantage, since this mirror secondary to needing a very large cooling that would be done by the usual procedures constantly used by industry and well known, having the advantage, that having consider the temperature so high that this mirror would reach secondary, it would be more than enough to take advantage of it by cooling and obtaining a first energy source. With my system of reflect these sun rays through the secondary mirror to accumulator we will be taking advantage of a calorific energy that in this moment is missing.

Also with my system, instead of producing electric power, we can send it directly as a source of massive heat, applicable to different purposes, such as heating or hot water installations for various purposes industrial, etc.

Drawings

As we had planned, all the production electrical we obtain from natural sources, (Fig. 1) the We send directly through a line (O), to a transformer (1) that will raise the voltage enough to power a calorific (2) as a voltaic arc or resistors, capable of generate a very high heat source, such as to transmit it to a appropriate flux material (4) and bring it to the melting point, whose high temperature heat will transmit part of it through of a heat exchanger (3) producing water vapor enough to move a turbine (6) connected to a electric current alternator (7), and this one, will be sent through of a transformer (8) with sufficient voltage for supply through the network (9).

In this way we close the entire circuit, which it will work only when the Network requires it, meanwhile, the initial electrical energy will be transformed into a great source of hot.

However we have a variant, according to the (Fig. 2) in the initial process of (O to 5), it is the same, but in this case, instead of producing electrical energy, that heat we would transmit as such, to use it massively through of a pump (7) as heat source for heating, water hot or any other destination (6).

Now, we can also use this system of high temperature accumulator, as we see in Figs. 3 and 4, with a variant, the energy input is not electric as we have described in Figs. 1 and 2, but this will come from the rays del Sol (1), which instead of being exploited in part through a tower where these fall, a system would be put in place divert them to this accumulator, and using the cooling that you need the reflection system, as the first source of energy such as now they are taking advantage of it and the rest, already diverted and very concentrated, which is currently lost, would enter the accumulator through a hole in the system (O) to reach the material willing to absorb this heat until it reaches the melting point (2) transmitting that heat through a heat exchanger (4) to produce enough steam from water and through a pump (5) drives a turbine which move an electric current generator as in Fig. 1 or a massive heat distribution described in Fig. 2. Of course, all enclosed in the insulating pile (3).
