More particularly, the present invention relates to a brown gas generating system capable of stabilizing power supply to a system by storing electricity generated by self-power generation, and using a large-capacity electrolytic cell, The present invention relates to a large-capacity brown gas generation system having a self-power generation and back-burning automatic prevention function that can be easily fabricated and assembled by changing the shape and structure of an electrode plate, and can reduce fabrication and operation costs.

In many industrial fields, gas combustion equipment using LPG, LNG, acetylene or brown gas as a combustion source is installed and operated.

In such a gas combustion facility, when the gas is ignited, abnormalities occur in the equipment or when the gas torch or the gas cutter tip is clogged or overheated, the flame is backed into the main body of the equipment and back flushing occurs, It erupts instantly and leads to serious disaster. Because of this, most of the gas combustion facilities are equipped with anti-backfire to prevent flame backlash to prevent explosion.

In particular, brown gas is a gas obtained by electrolysis of water, and is a mixed gas of hydrogen and oxygen at a ratio of 2: 1. When water is electrolyzed, hydrogen is obtained from the cathode and oxygen is obtained from the anode. It is Brown gas that collects these gases at once without collecting them separately.

Unlike general gas, Brown gas has a property of causing an implosion phenomenon in combustion. It does not show an explosion phenomenon during combustion, but instead forms a focal point and evacuates the surroundings, As a result, when brown gas is burned, an ultra high temperature which can sublimate tungsten having the highest melting point can be obtained. In addition, since the heat ray is not emitted to the outside and there is no energy loss due to radiant heat, it has an excellent energy efficiency, and it contains oxygen itself, so that no oxygen supply is required at the time of combustion, Do not.

1A, the conventional backfire prevention device includes an upper valve provided on a main supply pipe 20 provided between a gas generator 10 and a burner 50 for burning a gas, A flame adjusting tank 40 provided on the auxiliary supply pipe 30 and a lower valve provided on the upstream side of the flame adjusting tank 40. When the ignition or the fire is extinguished, And the lower valve is opened to allow the gas generated in the gas generator 10 to flow through the flame adjusting tank 40 to the burner 50 to prevent flame backing by mixing the gas and the flame adjusting agent.

However, since the organic solvent is burned and discharged as a pollutant, the gas is burnt in water, so backflushing can not be surely prevented, and when the gas has a large capacity, the problem becomes more serious.

1B, the electrolytic bath 60 of the brown gas generator is provided with a plurality of inner cylinders 62 inside the outer cylinder 61 together with the central rod 63, and upper and lower fixing plates 64 and 65 ). At this time, the outer cylinder 61 is formed into an upright cylindrical shape, and the inner cylinder 62 is formed into an upright cylindrical shape and functions as an electrode. Thus, when an electric current is applied to the outer cylinder 61 and the center rod 63, alternating inductive currents are generated in the plurality of inner cylinders 62, and a large number of positive and negative power sources are simultaneously operated, so that a large amount of oxygen and hydrogen are generated, will be. Such a conventional technique is also disclosed in Patent Document 1.

However, the electrolytic bath used in the above-described prior art is a small capacity that generates Brown gas at a maximum of about 5 m 3 / h. The shape of the inner cylinder (electrode plate) is an upright cylindrical plate having a circular planar section, The lower end portion is fastened to a plurality of grooves formed on the inner surface of the upper and lower fixing plates.

However, in the above-described prior art, an electrode plate having a circular section with a flat surface is difficult to obtain an accurate source, and is easily deformed into an elliptical shape or the like, whereby the surface area of the electrode plate becomes different, The generation of brown gas becomes uneven and unstable. In addition, since the electrode plate is made of a metal mold and the cost is greatly increased, it is difficult to manufacture the electrode plate because it needs to fabricate about 18 pieces at a small capacity, and a plurality of circular electrode plates must be inserted into the upper and lower fixing plates to be fastened. There is a problem. However, if the electrolytic cell is manufactured in a large capacity, it is impossible to surely prevent the overheating and the backflow of the flame, and the safety is not ensured.

Also, in order to generate brown gas with a large capacity, a large amount of electric power must be continuously supplied. However, the above-mentioned conventional technology has a problem that it is difficult to supply a stable power to the system when the power supply for power supply is stopped have.

And the frictional heat-resistant Teflon tube 912f is made of a glass teflon material doped with 10 to 20% by weight of glass, so that heat resistance and abrasion resistance are excellent and durability is increased.

In addition, the inverted branch pipe 912 is connected to the front end of the pipe so as to cover the end portion of the pipe, and a cover pipe 912g mounted on the pipe inner surface between the pipe 912f and the cover pipe 912g The rotation of the retainer R and the bearing B and the rotation of the rotation shaft 913 with the rotation shaft 913 while being in contact with the retainer R and the bearing B is connected to the outer end of the blade 913a, Sleeve 914 as shown in FIG.
