Abstract

The set is equipped with at least two pieces of generators, power inverter, which is composed of frequency generator and power switch, separator tank, filter tank and the cooling / heating heat exchanger, which cools the gas generators and may use their heat in the heating system at the same time. The mixture of water and gas is driven from the generators through cooling / heating heat exchanger into a separator tank where the gas is separated from the water, that gas is then driven into the filter tank where the gas is separated from the residual humidity, the gas is then ready at the output of the system for terminal device. Water from the separator tank is returned to the generators.

Description

Set of even number of generators for the production of gas with higher hydrogen and oxygen content by electrolysis of water and the supply inverter for more efficient production of gas and process of gas production
Technology area
The invention relates to construction of set of generators for production of gas with higher hydrogen and oxygen content (hereinafter referred to as gas) by electrolysis of water.
Present condition of technology
Currently, the gas production systems are mainly from fossil resources, gas production by electrolysis holds about 4 % of total production in the world, because it is known that electrolysis is ineffective. Another disadvantage of electrolysis is that electrical energy is still more expensive, so also the resulting gas produced by electrolysis is more expensive. Set of even number of generators for the production of gas by electrolysis of water solves more efficient and cheaper decomposition of water onto gas by rotation of power in the frequency at which the decomposition of water onto gas reaches the highest production.
Principle of technical solution
The above deficiencies are largely solved by a set of even number of generators for the production of gas by electrolysis of water according to this invention which uses for producion of gas the rotation of power in the frequency at which it achieves both the highest production and the lowest current offtake. Set design is based on other sets for gas production, but it is equipped with at least two pieces of generators, power inverter, separator tank , filter tank and the cooling / heating heat exchanger, which cools the gas generators and may use their heat in the heating system at the same time. Residual water is then returned back by the closed-circuit into generator. The mixture of water and gas is driven from the generators through cooling / heating heat exchanger into a separator tank where the gas is separated from the water, that gas is then driven into the filter tank where the gas is separated from the residual humidity, the gas is then ready at the output of the system for terminal device. Water from the separator tank is returned to the generators.
Set according to this invention is equipped with a power inverter which is composed of a frequency generator and power switch. The frequency generator generates pulses for the power switch that switches the power for two or more generators of the set. Thus it is achieved that the power is not brought to all generators in the set simultaneously, but only to the part, which alternates with the other parts of the set.
List of pictures on the drawings
Technical solutions will be further illustrated by a drawing in which Figure 1 shows a block diagram of the set of even number of generators for the production of gas, Figure 2 shows the construction of generators and Figure 3 shows a diagram of inverter power connection.
Example of technical solution conduct
Set of even number of generators for the production of gas by electrolysis of water (Fig. 1) consists of a main water tank \ , separator tank 2, set of two or more gas generators 3, gas filter tank 4, gas appliance 5, the cooling / heating exchanger 6, the appliance heat 7, circulation pump 8 and power inverter 9. Generator 3, the cooling / heating exchanger 6 and separator tank 2 are connected in a closed circuit, where the pump 8 provides the flow of water, from the main water tank 1 the water is released into the separator tank 2 in the way to prevent the leakage of gas. From the gas generator 3 a mixture of water and gas is going through the circulation pump 8 to the cooling / heating exhanger 6 and to the separation tank 2 where the gas is separated from the water, goes into the gas filter tank 4, where the rest of particles of water is filtered. At the output of the filter tank 4_the gas is ready to supply to the gas appliance 5. In the cooling / heating exchanger the replaced heat is ready to supply to the heat appliance. The generator 3 is connected to the power inverter 9.
Gas generator 3 (Fig. 2) is composed of electrodes 10, seal JJ., setting bars 12 and fronts 13. The generator is composed of a certain number of electrodes 10 and seal ϋ in order to achieve such a voltage on the electrode which is effective for decomposition of water into gas. The power inverter 9 (Fig. 3) consists of a frequency generator G, the switch 14 and the two halves of generator set 15 and 16. Frequency generator G generates a frequency for the switch 14 which switches power between the two halves of an even number of generators 1_5 and 16. Frequency generator G generates a certain frequency to provide the decomposition of water in the two halves of an even number of generators 15 and 16 the most effective, ie. at the lowest power the highest production of gas.
Industrial efficiency
This technical solution is especially designed for more efficient gas production, it reduces costs associated with the production and increases gas production.
