Description
METHOD FOR GENERATING OXYGEN/HYDROGEN GAS
Technical Field
[1] The present invention relates to a method for generating oxygen/hydrogen gas, and in particular, relating to a method for generating oxygen/hydrogen gas using the discarded storage battery which is a kind of industrial waste. Background Art
[2] Generally, an equipment for generating oxygen/hydrogen gas is an equipment for generating oxygen and hydrogen by performing electrolysis of water; the equipment generates oxygen/hydrogen gas by providing water, to which small amount of electrolyzed material (electrolyte) is added, to an electrolyzer in which a positive electrode and a negative electrode are arranged, and applying direct current.
[3] Here, usually the oxygen/hydrogen gas is generated which oxygen and hydrogen is mixed at the ratio of 2: 1.
[4] Since this equipment for generating oxygen/hydrogen gas is considered as an energy source without generating any polluted materials, the importance of it is being stressed by the serious environment problems. Korean Laid-Open Patent Publication No. 2004-0083754 (an equipment for generating oxygen/hydrogen gas, and a control method thereof), and a registered Utility Model Publication No. 0252564 (an equipment for generating a mixed gas) can be enumerated as examples.
[5] On the other hand, the method for generating oxygen/hydrogen gas using a conventional generating equipment formed as above will be briefly explained as follows.
[6] If current is applied to an electrode plate arranged in an electrolyzer, the electrode plate performs electrolysis on the electrolyte accommodated in the electrolyzer, bubbles are generated on the surface of the electrode plates during this process, and the gas contained in the bubbles is the oxygen/hydrogen gas.
[7] That is, after the bubbles containing oxygen/hydrogen gas rise above the surface of electrolyte, and are burst out, then oxygen/hydrogen gas contained in the bubbles is discharged to outside and is charged to a filling tank, thereby it can be used as an energy source.
[8] However, as illustrated above, in a conventional equipment for generating oxygen/ hydrogen gas, and a method thereof, since additional electrode plates are stacked in an electrolyzer, and a space member such as a rubber material (or other material) is arranged between them, there are shortcomings that the cost of the equipment for generating oxygen/hydrogen gas increases and the manufacturing processes and time also increase.
Disclosure of Invention
Technical Problem
[9] Therefore, in order to solve the above problems, the object of the present invention is to provide a method for generating oxygen/hydrogen gas using a discarded storage battery. [10] Another object of the present invention is to provide a method for generating oxygen/hydrogen gas using a discarded storage battery for preventing an environment pollution created by a discarded storage battery. [11] In addition, still another object of the present invention is to provide a method for generating oxygen/hydrogen gas using a discarded storage battery for preventing loss of unnecessary resources. [12] In order to accomplish the above objects, the present invention suggests a method for generating oxygen/hydrogen gas by eliminating the sulphuric acid filled inside the discarded storage battery and then, filling the electrolyte including water of 70-90 weight% and potassium hydroxide of 10-30 weight% into the storage battery.
Technical Solution [13] After collecting the discarded storage battery and eliminating the sulphuric acid solution filled in discarded storage battery completely, electrolyte including H O of 80 weight% and potassium hydroxide (KOH) of 20 weight% is filled in the discarded storage battery (hereinafter, referred to as a discarded battery)
Advantageous Effects
[14] As illustrated above, according to the present invention, since the discarded battery is re-used for generating oxygen/hydrogen gas, it is not necessary to use an electrolyzer in which additional electrode plates are stacked, and thus, there are advantages that the cost of an equipment for generating oxygen/hydrogen gas can be reduced remarkably and the manufacturing processes and the time can also be reduced. Further, an environment pollution created by a discarded battery can be prevented in advance and loss of unnecessary resources can also be prevented. Best Mode for Carrying Out the Invention
[15] Below, the preferred embodiment of the present invention will be explained in detail
[16] In the detailed specification described later, a typical embodiment of the present invention will be suggested in order to solve the technological problems. Further, other embodiments which are suggested by the present invention will be explained in the structure description of the present invention.
[17] The present invention is a method for recycling the storage battery used in various kinds of industrial fields and automobiles, and preferably, the object of the present
invention is to implement a method for generating oxygen/hydrogen gas by using a discarded battery, and such a method is suggested in detail in the following embodiments.
[18] [Embodiment 1]
[19] After collecting the discarded battery and eliminating the sulphuric acid solution filled in discarded battery completely, electrolyte including H O of 80 weight% and potassium hydroxide (KOH) of 20 weight% is filled in the discarded battery (hereinafter, it is called as a discarded battery)
[20] Subsequently, oxygen/hydrogen gas is generated by using a discarded battery. Here, a plurality of discarded batteries can be used simultaneously.
Claims
[1] A method for generating oxygen/hydrogen gas using a discarded storage battery comprising: a step of eliminating sulphuric acid filled inside a storage battery; and a step of filling electrolyte into the storage battery for generating oxygen/hydrogen gas.
[2] The method for generating oxygen/hydrogen gas using a discarded storage battery as claimed in claim 1, wherein the electrolyte is composed of water of 70-90 weight% and potassium hydroxide of 10-30 weight%.
