Description

Method of Obtaining Magnesiun And Apparatus System For Obtaining Magnesiun

The present invention relates to a magnesium manufacturing method and a magnesium manufacturing system, and more specifically, to forcibly suck out dust, high temperature heat, toxic gas and the like discharged from the slag discharge from the magnesium extraction furnace through the bogie and vacuum intake apparatus The present invention relates to a magnesium production method and a magnesium production system that can prevent the diffusion of dust, high temperature heat, toxic gases, etc. into the workplace.

Magnesium is an element that is present in the earth's crust as well as in seawater.In 1808, British chemist H. Davie reduced magnesia (MgO) to metal potassium and extracted a small amount of metal for the first time. B. Reducing agent for titanium production and used as an alloy source of aluminum material. However, since 2000, it has light weight, high thermal conductivity, specific strength, heat dissipation, and has 2/3 of aluminum and 1/5 of iron. According to various material characteristics such as electromagnetic shielding, as the utilization is gradually expanded to transport equipment such as automobiles or IT industry materials, production is also rapidly increasing.

In general, smelting of magnesium metal can be divided into electrolytic and metal thermal reduction. In the early days when magnesium was discovered, mass production has been carried out through magnesium electrolysis facilities built in countries such as Norway and Canada, where low-power electricity can be supplied through hydropower from seawater or magnesite.

Since then, the magnesium heat reduction method developed by Dr. Pigeon in Canada in 1941 has been transferred to China since the mid-1990s, with high-quality, rich dolomite minerals used as raw minerals, inexpensive human resources, and no environment. Due to the rapid quantitative growth of regulations, magnesium metal production by Western-based electrolysis was reduced to the loss of competitiveness, and magnesium production by China-based thermal reduction method rapidly increased, and as of the end of 2007, global production reached 810,000 tons. In China, more than 80% of these are produced by thermal reduction in China.

Magnesium is not naturally produced in the free state, but it is widely and largely present on earth as carbonates and silicates, and the amount in the crust is the eighth place after sodium and potassium. Major mineral resources are magnesite, canalite, dolomite, talc, serpentine, etc.Magnesite, dolomite, and canrite are mainly used as magnesium raw materials for electrolysis, and dolomite is used for thermal reduction. .

Magnesium smelting Pigeon heat reduction method developed in Canada, but developed in China, mainly used anthracite coal as a fuel and used it as a heat source for calcination of dolomite and heat reduction furnace. Sox, NOx and CO As a source of environmental pollution, it is generally recognized as an energy-consuming environmental pollution facility.

In addition, the horizontal retort of the Pigeon heat-reduction furnace is a magnesium manufacturing process through external heating, which is an intermittent operation facility requiring about 8 hours of reduction and 3 hours of cooling time. On the other hand, the production of opposing magnesium has a limitation in productivity, and the operation is performed by manual labor by a large amount of manpower under poor environmental conditions.

The existing Pigeon heat reduction method is basically a horizontal heat reduction reaction tube whose shape is closed at one end, and charges the raw material for manufacturing magnesium depending on manual labor and installs a condenser with a cooling jacket at the entrance of the reaction tube. While producing a magnesium crown by heat reduction while making the inside of the furnace (vacuum) into a vacuum, the loading of the raw material and the discharge of the product had a problem that is dependent on the manpower.

In addition, the heat reduction reaction tube is also mounted horizontally in a high-temperature atmosphere furnace, and has a limitation in multi-stage installation. The heat reduction reaction tube is limited to two installations in commercial facilities, and the limitation of the installation of the heat reduction reaction tube per unit volume is limited. Furnace has a limitation in productivity, and therefore has a limitation in mass production.

In addition, in the conventional heat reduction process, anthracite coal has been mainly used as a predetermined source or energy source of the heat reduction furnace, and as a result, many environments such as SOx, NOx, and CO are generated due to dust generation and combustion of anthracite coal. Emission of pollutants is inevitable.

Therefore, this also needs to be improved.

In order to improve the intermittent operation of the Pigeon thermal reduction method, charge magnesium oxide raw material continuously calcined ore into the upper part of the furnace body, and melt it at about 1500 ~ 1600 ℃ by using a high-temperature melting furnace, and melt the silicon metal in the molten state. The Magnesite method of reducing magnesium to produce magnesium was commercially developed and commercialized in France earlier, but after the operation of the heat reduction smelting facility in the Pecheney region of France, which was commercialized for the first time due to technical limitations due to the use of electricity, This was not done, and the facility also shut down in the early 1970s.

In South Africa in the early 2000s, a similar magnesium heat reduction and smelting plant was developed up to the scale of a pilot plant.In contrast, unlike the magnesite process in which the heat reduction reaction proceeds under vacuum conditions, Mintech (Metal Tech) is developed to dissolve and smelt under high temperature conditions.
