Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar-based gas production device that uses a solar cell and uses its electromotive force to electrolyze an electrolyte to generate gas.

Conventionally, sludge production has been carried out by electrolyzing electrolyte (e.g., salt water, etc.) to generate and collect sludge (e.g., chlorine scum, hydrogen gas, etc.). High voltage alternating current generated in a remote location from
Currently, it is used by directly replacing it with 1fL at the factory. In addition, the power loss lost during the equipment and power transmission is completely wasted, resulting in energy loss, and also increases equipment costs.

This invention is completely different from the conventional use of commercial power, and aims to generate and collect gas easily and inexpensively in a semi-permanent continuous manner by utilizing the infinite and infinite solar energy as it is. The purpose is to provide appropriate equipment for this purpose.

The gist of this invention is that solar cells with opposite polarities are placed adjacent to each other in an insulated manner on the bottom surface, and an electrolyte is applied to each of the solar cells through a dust-impermeable and conductive diaphragm between the two solar cells. Put it on,
Moreover, the upper part is a gas production equipment using solar power generation, which has a sealed structure as a translucent wall. Specifically, the upper wall, side wall,
It is a box with a sealed structure that includes a bottom wall and a partition wall that extends from the bottom wall to the top wall and divides it into two left and right units, and on the upper surface of the two bottom walls, there are solar cells each having a pn layer upside down relative to each other. The upper wall is made of a translucent material, the side wall is made of an electrically insulating material, and the bottom wall is made of a highly conductive material, and the partition wall is made of an impermeable electrolytic diaphragm or an ion exchange membrane. This is a solar scum production device that can generate scum by electrolysis using the electromotive force of a solar cell by filling two units with a specified electrolytic solution.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The gas production apparatus 1 shown in FIG. 1 includes an earthen wall 2, a surrounding side wall 3, a bottom wall 4, and a wall extending from the bottom wall 4 to the top wall 2 and dividing it into left and right rooms A and B. It is a box with a rich 1,1 structure equipped with Xt5.

Solar cells 8A and 8B having pn layers opposite to each other are disposed on the bottom wall 4-1 of the left and right sides, respectively.

The 1-wall 2 is made of a transparent material such as glass that allows sunlight to pass through, and the side wall 3 is made of an electrically insulating material and-
1- It is made of crow etc. so that the sunlight can pass through not only the wall 2 but also the side wall 3.

The lower part 7 of the partition 5 in contact with the solar cells 8A and 8B is made of an electrically insulating material such as a synthetic resin, and the upper part 6 of the partition 5 is made of an electrolytic diaphragm such as a porous ceramic thin film or a polyethylene thin film without air permeability, or an ion-containing electrolytic diaphragm such as a porous ceramic thin film or a polyethylene thin film. It is made up of an exchange membrane.

In addition, gas pipes 10 connected to gas suction means are separately installed in the left and right royal houses A and B. Therefore, A
For example, if easily available seawater is filled in both chambers of B and the gas production equipment 1 is exposed to sunlight, the large sunlight will pass through 1-wall 2, side wall 3, and seawater 9 and illuminate solar type-&8 A and 8B. In turn, the p layer of the pn layer of the solar cell 8A in room A acts as an anode, and the n layer of npR of the solar cell 8B in room B acts as a cathode to generate an electromotive force.

Here, the generally known electrolytic reaction is NaCl +
)I 0-4y2CI + 4 )12 + /N
aD)12, and the electrolytic voltage required for this electrolytic reaction (mar, 36■
Therefore, if an amorphous solar cell is used in the solar cells 8A and 8B4, an electromotive force of 1.5 to 1.6V can be obtained, and if a potassium arsenic solar cell is used, an electromotive force of 2.5V can be obtained.
An electromotive force of 15% is obtained, and the electrolyte level is sufficiently increased to 15%.

Then, the electrolytic current flows from the second layer of the solar cell 8A in room A to the seawater 9 in room A, the upper part of the partition wall 6, the seawater 9 in room B, and the n layer of solar cell 8B in room B, and the seawater 9 is electrolyzed. Chlorine gas is generated in chamber A, and hydrogen gas is generated in chamber B. In addition, seawater 9
The amount of water that can be put into both rooms A and B is a lomf that creates space in the two parts and does not reduce the sunlight transmittance too much.
Appropriately, it should be about fl or less, preferably about 5 to 6 mm. Of course, this (f4) will depend on the flow rate when 1IIJ water is left standing, the flow rate when flowing water, the amount of sunlight when irradiated, etc.

The gases generated in both chambers A and B are not mixed by the impermeable partition wall 6, but are sucked through the gas %l'lO, and can be stored separately in a storage tank.

In addition, as another example, if a zinc sulfate aqueous solution is used as the electrolyte, as is well known, 2ZnSO4+ 2)
120 → 2Zn + 2H2So4+ Oxygen scum is obtained based on 02.

The gas production device 11 shown in FIG. 2 is constructed by arranging the gas production devices 1 shown in FIG. The gas pipe 10 is located on the upper side, and the opposite side is located on the lower side. It is configured with numbers so that it flows smoothly.

By the way, the electromotive force 1 of gas production equipment No. 11 shown in Fig. 2
．． If a 5V amorphous solar cell is used and seawater with a salinity of 34 g is poured into it during sunlight irradiation, a solar cell 8A with the p layer of the pn layer located on the surface, and a solar cell with the n layer of the np layer located on the surface For each 1 m' of 8B, approximately 4 g/m'h of chlorine gas and 0.11 g/m'h of hydrogen force can be generated.

In both Examples, readily available seawater was used as the electrolyte to produce chlorine gas and hydrogen scum; however,
Of course, it is also possible to obtain the desired gas by using an electrolytic solution such as a zinc sulfate aqueous solution or a lithium fluoride aqueous solution.

In both embodiments, the side wall 3 is made of transparent electrically insulating material such as glass to increase the amount of sunlight irradiated to the solar cell 8. The side wall 3 does not necessarily need to be made of transparent wood 1 as long as sufficient normal incidence of sunlight can be made to the battery 8.

The dregs production device according to the present invention has the above-described configuration and operation, and uses a solar cell that generates an electromotive force from sunlight as the electrode itself, which is completely different from the conventional use of commercial power. , unlimited and free solar energy can be utilized, electrolysis of electrolyte can be carried out continuously, easily and inexpensively, and the desired gas can be produced. In particular, when producing hydrogen gas, chlorine gas can be produced extremely energy-savingly and at low cost because it uses seawater, which is extremely easy to enter, and also utilizes inexhaustible sunlight.
