The invention concerns a hydrogen and oxygen generation device, which is composed of two adjacent liquid tanks that are connected to each other, and where one of the tanks contains an anode and the other tank contains a cathode, and where a current is supplied to the anode and cathode in order to separate hydrogen and oxygen from the liquid.

Hydrogen and oxygen generation devices such as this, where water molecules are disintegrated into hydrogen and oxygen, can be found in various configurations and types even in physics textbooks. The purpose of this invention is to accomplish a new type of a hydrogen and oxygen generation device, which is efficient and which can also process waste water, from which waste sludge is separated. It is characteristic of the hydrogen and oxygen generation device according to the invention that the anode and cathode are composed of plates placed on top of each other, with liquid-absorbent sheets between the plates, and that liquid, from which hydrogen and oxygen are separated, can be led into the tanks. The solution according to the invention accomplishes a very large surface area both for the anode and cathode, and hence a very high efficiency. While hydrogen and oxygen are separated from the waste water, waste in a compacted form can be separated from the waste water. The various embodiments of the invention are presented in the non-independent patent claims.

In what follows, the invention is described by means of an example by making reference to the enclosed drawing, which presents a section of one embodiment of the hydrogen and oxygen generation device. A hydrogen and oxygen generation device, which is composed of two adjacent liquid tanks (1, 2) that are connected to each other, and where one of the tanks contains an anode (3) and the other tank contains a cathode (4), and where a current (5) is supplied to the anode (3) and cathode (4) in order to separate hydrogen and oxygen from the liquid. The anode (3) and cathode (4) are composed of plates (6) placed on top of each other, with liquid-absorbent sheets (7), such as blotting paper, pulp sheets or corresponding liquid-absorbent sheets, between the plates. This gives a very large surface area for the anode (3) and cathode (4). Liquid (8), such as waste water, can be led into the tanks (1, 2), and hydrogen, oxygen and waste are separated from the liquid. The plates (6) are perforated so that the liquid can better absorb into the anode (3) and cathode (4). On top of the anode (3) and cathode (4), there are electromagnets (9), with which magnetic particles can be removed from the waste water. The magnets (9) also serve as weights, which compress the anode and cathode packs together. At the bottom part of the tanks (1, 2), there are waste removal funnels (10), through which the waste sludge removed from the waste water can be removed. The edges of the anode and cathode packs (3, 4) are supported by means of angle irons (11), which also serve as support legs.
