Abstract

PROBLEM TO BE SOLVED: To use brown gas which can be manufactured with high electric power with good profit in domestic as a result of consideration whether silicon can be manufactured in domestic rather than importation as a metal silicon currently.SOLUTION: Silicon dioxide can be reduced by mixing coal and silica rock or the like by brown gas and sublimating both and is divided into silicon and carbon dioxide. The brown gas which can provide super high temperature is used because they are burned by a sublimation temperature.SELECTED DRAWING: Figure 1

Description

本発明は、シリコン(ケイ素Si)を国内で生産する製造装置である。
日本国内の珪砂、硅石、シリカなどの埋蔵量は2億トンあるとされているが、現状は製造過程で大容量の電力が必要なため安価な外国製のシリコンを使用している。
The present invention is a manufacturing apparatus for producing silicon (silicon Si) in Japan.
The reserves of silica sand, meteorite, silica, etc. in Japan are estimated to be 200 million tons. Currently, cheap silicon is used because it requires a large amount of power during the manufacturing process.

シリコンは珪砂、硅石、シリカなど酸化ケイ素SiOが主原料の鉱物から還元して作られる。工業用ケイ素(シリコン)を作るにはアルミニウム同様、酸化物から還元するには大容量の電力を必要とする。
そのため、外国の安い電力の電気炉(アーク炉)で製造された金属シリコンを輸入するのが一般的である。 なぜ大容量の電気が必要になるのかと言うと、還元剤に炭素(カーボン)を使用して二酸化ケイ素SiOの脱酸を行うために、高温(3,642℃以上)が必要になる。そこで、外国ではアーク放電によって高温を出している。
日本では電気代が高く採算が合わないと言うことである。
なにも電気ばかりに頼らなくても、超高温を出せるガスがある。
本発明はそのガス(ブラウンガス)を使って二酸化ケイ素を還元し、金属シリコン(ケイ素)を製造するものである。
Silicon is made by reducing silicon oxide SiO 2 such as silica sand, aragonite, and silica from minerals as a main raw material. To produce industrial silicon (silicon), like aluminum, reduction from oxides requires a large amount of power.
For this reason, it is common to import metal silicon manufactured in an electric furnace (arc furnace) with a cheap electric power in foreign countries. The reason why large-capacity electricity is required is that high temperature (3,642 ° C. or higher) is required in order to deoxidize silicon dioxide SiO 2 using carbon as a reducing agent. Therefore, high temperatures are generated by arc discharge in foreign countries.
In Japan, electricity bills are high and not profitable.
There is a gas that can produce ultra-high temperatures without relying solely on electricity.
In the present invention, silicon dioxide is reduced by using the gas (Brown gas) to produce metal silicon (silicon).

ブラウンガスは現在溶接機(接断機)として多く用いられている。
用途はいくらでもあると考えられているが、以外と利用されていない。
したがって、このような超高温を出す燃料としての利用は現在研究中のようだ。
Brown gas is currently widely used as a welding machine.
It is considered to have many uses, but it is not used for anything else.
Therefore, it seems that research on the use of such a fuel as an ultra-high temperature is under study.

珪砂等二酸化珪素の融点は1,650℃、沸点は2,230℃である。
カーボン(炭素)の昇華点は3,642℃で、炭(木炭、竹炭等)の昇華点も3,642℃と考えられる。 二酸化珪素を還元するにはカーボンの昇華点3,642℃以上必要である。 日本の電気炉内で珪砂と炭をブラウンガスで燃焼し昇華温度3,642℃以上の温度にすれば良いことになる。 ただ排気ガスは多量の二酸化炭素を含んでおり、そのまま大気に放出することができない。地球温暖化対策にならない。
The melting point of silicon dioxide such as silica sand is 1,650 ° C. and the boiling point is 2,230 ° C.
The sublimation point of carbon (carbon) is 3,642 ° C., and the sublimation point of charcoal (charcoal, bamboo charcoal, etc.) is also considered to be 3,642 ° C. In order to reduce silicon dioxide, a sublimation point of carbon of 3,642 ° C. or higher is necessary. In a Japanese electric furnace, silica sand and charcoal are burned with brown gas to a sublimation temperature of 3,642 ° C. or higher. However, exhaust gas contains a large amount of carbon dioxide and cannot be released into the atmosphere as it is. It is not a measure against global warming.

電気炉内は高温でも耐火性能が可能だと考えているが、排気ガスの処理(二酸化炭素)をするのに工夫をした。 本発明者が以前特許申請した(現在申請中)ように排気ガスを水洗ブースにぶつけて、二酸化炭素を水中に溶け込ます。 この工程を経由して大気に放出する。そうすることで地球温暖化防止が図られる。
SiO + C → Si + CO
(イ)電気炉内に炭(木炭、竹炭、オガ炭)と珪石(珪砂、シリカ)を入れ、上部、サイド数か所からブラウンガスバーナーで燃焼する。
(ロ)珪石等は1,650℃で溶融するが、炭の一部は燃えてガスになるが残っている炭はまだ固体のままである。
(ハ)さらにブラウンガスを数か所から燃焼して炉内の温度を3,642℃以上にする。 ただし炉壁は3,642℃にはならない。これはエンジンの内壁とピストンの関係のように内部温度が超高温でも接触する面は温度がドロップする。
(ニ)電気炉上部から外気を取り入れ排気ガス温度を2,000℃位に落として気化しているケイ素(シリコン)を沸点以下にして液状で取り出す。
(ホ)2,000℃以下になっている排気ガスを、排風機を用いて、水洗ブースに当てて、COを取り除いてから大気に放出する。
(ヘ)その後の排気ガスは発明者が既に特許申請しているように行う。
(ト)ケイ素(シリコン)は液状のまま、電気炉から取出し冷却固化する。 固化後容器から取り出す。
Although the electric furnace is considered to be capable of fire resistance even at high temperatures, it has been devised to treat exhaust gas (carbon dioxide). As the inventor previously applied for a patent (currently pending), exhaust gas is struck into the washing booth and carbon dioxide is dissolved in water. It releases to the atmosphere via this process. By doing so, global warming can be prevented.
SiO 2 + C → Si + CO 2
(B) Put charcoal (charcoal, bamboo charcoal, oga charcoal) and silica (silica sand, silica) in the electric furnace, and burn with a brown gas burner from the top and several sides.
(B) Silica and the like melt at 1,650 ° C., but some of the charcoal burns into gas, but the remaining charcoal remains solid.
(C) Further, brown gas is burned from several places to raise the temperature in the furnace to 3,642 ° C. or higher. However, the furnace wall does not reach 3,642 ° C. This is because the temperature of the contact surface drops even if the internal temperature is very high, such as the relationship between the inner wall of the engine and the piston.
(D) Taking outside air from the upper part of the electric furnace, lowering the exhaust gas temperature to about 2,000 ° C. and taking vaporized silicon (silicon) below the boiling point and taking it out in liquid form.
(E) Exhaust gas at 2,000 ° C. or lower is applied to a water washing booth using an exhaust fan to remove CO 2 and then released to the atmosphere.
(F) Subsequent exhaust gas is performed as if the inventor has already applied for a patent.
(G) Silicon (silicon) is taken out from the electric furnace in a liquid state and solidified by cooling. Remove from container after solidification.

ケイ素(シリコン)は外国から金属シリコンとして輸入しているが、この装置が完成すれば国内で製造ができ安くて便利になる。
(イ)他国に頼らなくても良い。安定して供給できる。
(ロ)輸入コストよりも安くつく。
(ハ)他国の影響を受けにくい。
(ニ)金属シリコンを輸入した後の工程も同時に行える可能性がある。
(ホ)珪砂、硅石、シリカ等から純度の高いシリコンを製造するのに、また加工するのにワンステップで出来る可能性がある。
Silicon (silicon) is imported from foreign countries as metallic silicon, but once this device is completed, it can be manufactured domestically and becomes cheap and convenient.
(B) There is no need to rely on other countries. It can be supplied stably.
(B) It is cheaper than the import cost.
(C) Not easily affected by other countries.
(D) There is a possibility that the process after importing metallic silicon can be performed at the same time.
(E) Production of high-purity silicon from silica sand, meteorite, silica, etc. may be possible in one step for processing.

構造Construction

本発明を使用するときは以下の手順で行うWhen using the present invention, the following procedure is used.

(イ)電気炉(電気炉と言っても電気で加熱するものではない。)に炭(木炭、竹炭、オガ炭等)と珪砂、硅石、シリカ等を混ぜて入れる。
(ロ)可動式のバーナーで上部からブラウンガスで燃焼すると同時に、固定式のバーナー数か所(炉壁内に埋め込み式)からもブラウンガスで燃焼する。
(ハ)珪石等は1,650℃で液状化し、2,230℃位で気化するので、炭素の昇華温度の3,642℃以上に急速に燃焼する。
(ニ)燃焼したガスを電気炉上部のホッパーで捕集して、そのガスを電気炉壁の横の混合気室に導き外気を取り入れて温度を下げる。
(ホ)混合気が2,230℃以下になるとシリコンが液状化して混合気室下部の受け皿に溜まる。もし液状化しても下部に落ちない場合は混合気室に液体が落ちやすいように格子状の棒を数か所設置すれば良い。
(ヘ)混合気を出たガスは二酸化炭素が多く含まれているので、この二酸化炭素を取り除くために水洗ブースへと導く。
(本発明は水洗ブースまでで、水洗ブース以降は別途特許申請している。)
(ト)シリコンが液状化して受け皿に溜まり、原料(炭、硅石等)がなくなり燃焼も終わると一工程が終わったことになり、受け皿が冷えて(1,650℃以下で固化)からシリコンを取り出す。
(B) Mix charcoal (charcoal, bamboo charcoal, oga charcoal, etc.) with silica sand, meteorite, silica, etc. into an electric furnace (even if it is called an electric furnace, it is not heated by electricity).
(B) Burning with brown gas from the top with a movable burner, and burning with brown gas from several fixed burners (embedded in the furnace wall).
(C) Silica stone liquefies at 1,650 ° C. and vaporizes at around 2,230 ° C., so it rapidly burns to a carbon sublimation temperature of 3,642 ° C. or higher.
(D) The burned gas is collected by a hopper at the top of the electric furnace, and the gas is introduced into the gas mixture chamber beside the electric furnace wall to take in outside air and lower the temperature.
(E) When the air-fuel mixture reaches 2230 ° C. or lower, the silicon liquefies and accumulates in a tray at the lower part of the air-fuel mixture chamber. If the liquid does not fall to the bottom even if liquefied, several grid-like bars may be installed so that the liquid can easily fall into the gas mixture chamber.
(F) Since the gas out of the air-fuel mixture contains a large amount of carbon dioxide, it is led to the washing booth to remove this carbon dioxide.
(The present invention extends to the washing booth, and patents have been filed separately after the washing booth.)
(G) The silicon liquefies and accumulates in the saucer, and when the raw material (charcoal, meteorite, etc.) runs out and combustion ends, one process is complete. Take out.
