As shown in the above table, the most serious equipment used in the field, the oil jet burner, has been pointed out as a serious noise pollution problem. Moreover, when oil prices soar in the high oil price era, it is more a problem because the price is not correct due to the fuel cost to be paid tens of millions of won per month.

Therefore, the present invention is to solve the noise pollution problem by providing a brown gas rock cutting equipment and to solve the fuel cost problem at the same time by using brown gas as a fuel instead of oil.

Brown gas is a completely pollution-free fuel produced by electrolysis of water and is a mixed gas in which hydrogen and oxygen are mixed in a chemical equivalence ratio of 2: 1 as the composition of water. Brown gas is an ideal new fuel that does not require combustion air during combustion. It is a new concept of new energy that is completely burned by its own oxygen.

The flame of New Energy Brown Gas forms a pinpoint flame that gathers toward one point without spreading the flame. This shows that the phenomenon of continuity is continuous and there is almost no side heat, but it has tremendous energy at the pinpoint, so that the refractory brick can be drilled as it is.

Brown's flame has a unique characteristic of reacting hydrogen and oxygen in atomic and molecular states. Hydrogen atoms and oxygen atoms penetrate between the nuclei of the material to be heated. Hence, materials heated by thermonuclear reaction by hydrogen and oxygen are heated by heat that is much hotter than the flame when the gas burns alone in the air. Brown gas, which exhibits different thermonuclear properties depending on the material to be heated, Iron can be welded as it is.

As described above, the present invention applies the brown gas rock cutting equipment including the brown gas burner for rock cutting by applying the characteristics of the brown gas which emits high heat according to the material to be heated and the flame to go straight while making the pinpoint flame. It is to provide.

The conventional oil jet burner is a tool for cutting granite by using a hot flame, and is mainly used in opening a quarry. The pressure is 5 ~ 6kg / cm² of compressed air and fuel (kerosene or diesel) and is ejected from the nozzle. The flame spraying speed is 1200m / sec. Due to its light weight, it is free to transport, which contributes to the working conditions. The depth of cut is usually 5m but can be up to 8 ~ 10m. However, since high-temperature and high-speed flames are ejected to the nozzle, a very loud noise is generated, and since dust is blown badly by the hot air ejected from the nozzle, dust is also generated and pollution problems are raised.

In this case, kerosene or light oil requires a lot of combustion air, so it is forced to inject excessive compressed air, resulting in violent noise, which is up to 160db, which is higher than jet noise (120db).

However, because Brown's gas is an ideal fuel that is completely burned by its own oxygen, compressed air is only used to blow out rock fragments, so about one quarter of the oil jet burner is sufficient. Therefore, the noise is greatly reduced and there is no pollution problem.

The water fuel automatic supplying device of the present invention is a brown gas mass generator and a brown gas incorporating a brown gas gas and a brown gas mass generation device having a 96% electrolytic efficiency and an automatic water supply device for supplying tap water to a brown gas generator. It consists of a gas compressor for sending up to and a NO.1, NO.2 fresh bag arrester installed before and after the gas compressor, and a brown gas burner for rock cutting.

The gas compressor repeatedly starts and stops with the NO.1 and NO.2 pressure switches mounted on the NO.1 and NO.2 fresh bag arresters, for example, the upper limit setting value of the NO.2 pressure switch. Stop operation above 2kg / cm² and stop operation below 0.5kg / cm² lower limit setting value of NO.1 pressure switch.No.1 freshbag arrester while the pressure of NO.2 freshbag arrester is below 2kg / cm² It is configured to operate only at pressure of 0.5kg / cm² or more.

Brown gas burner, which is a key element of the present invention, has a burner body made of a pipe of a predetermined length, and a brown gas supply pipe is installed inside the body, and compressed air is supplied to the surrounding space, and the burner head and burner head connected to the brown gas supply pipe are formed. A certain number of nozzle necks and nozzle tips are assembled on the upper part of the burner head cap assembled with the O-ring between them, and the nozzle tip is configured to be detachable.

In addition, the compressed air nozzle is assembled on the center line of the burner head, and the nozzle end forms a nozzle hole to face the front of the burner at an angle with the center line. In relation to the direction of the compressed air nozzle hole, the Brown gas nozzle has a predetermined number toward the back of the burner based on the burner center line. The nozzle tip protective cover that is finally assembled is configured to protect the nozzle tip by showing a shape that is open toward the front of the burner.

In this way, the brown gas supplied from the brown gas supply pipe is supplied to a plurality of nozzles formed at the upper part of the burner cap along the brown gas passage so that it can be ignited at the burner tip, and the compressed air passes through the compressed air hole to the compressed air nozzle. The nozzle hole at the end of the nozzle is formed so as to form a predetermined angle with the nozzle center line so as to blow off the stone powder or rock fragments effectively when the compressed air is ejected.

As described above, an object of the present invention is to provide a brown gas rock cutting equipment that can solve the fuel cost problem and noise pollution problem of the existing oil jet burner at the same time.

In order to achieve the above object, the present invention applies the combustion characteristics of brown gas only that does not require combustion air to create a brown gas burner for rock cutting, and to construct a water fuel automatic supply facility for stably supplying brown gas to the burner. You must do it.

Water fuel automatic supply facility, that is, Brown gas plant has patent body No. 0050835, "Brown gas mass generator including column type electrolyzer", which is registered and applied by the inventor, and installed supplementary water automatic supply device and automatic flashback prevention device. I'm doing it.

The Brown gas plant has a gas operating pressure of 1 kg / cm² or less. However, in order to supply Brown gas from the quarry to the distant work place, the gas supply hose has to be long, so the gas pressure must be increased.

Therefore, the present invention is to increase the gas supply pressure to more than 2kg / cm² by using a gas compressor so that the problem of the gas length of more than 100m Brown gas. The gas compressor is installed between the NO.1 fresh bag arrester and the NO.2 fresh bag arrester and the pressure switch is installed on the top of the NO.1, NO.2 fresh bag arrester so that the gas compressor operates automatically according to the set pressure. do. According to the experiment of the present inventors, the gas compressor confirmed that the small model 80324 was sufficient in the gas booster manufactured by Haskell, USA.

Therefore, the automatic water fuel supply system of the present invention is configured to supply brown gas at a pressure of 2 kg / cm² when the gas valve is opened when using the brown gas burner, and the brown gas burner connected to the hose has a predetermined number of brown parts at the burner head. After the gas nozzles are ignited, the hot rocks are blown out by the high temperature Brown Gas flames emitted from each nozzle tip, causing them to intercept according to the temperature difference.

In addition, by forming a compressed air nozzle in the center to blow the stone powder and fragments crushed by the brown gas flame with compressed air to achieve the objective by effectively cutting the rock.

Hereinafter, the brown gas rock cutting equipment according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
