Abstract
The invention discloses a device for eliminating a settled layer at the furnace bottom of a submerged arc furnace. The device comprises a metal pipe, a pressure-resisting leather pipe and a high-pressure gas cylinder. The outer portion of one end of the metal pipe is coated with a high-temperature-resisting coating, and the other end of the metal pipe is used for being connected with one end of the pressure-resisting leather pipe. The other end of the pressure-resisting leather pipe is used for being connected with a gas outlet of the high-pressure gas cylinder. The invention further discloses a method for eliminating the settled layer at the furnace bottom of the submerged arc furnace. By means of cooperation of the high-temperature-resisting metal pipe, the pressure-resisting leather pipe and the high-pressure gas cylinder, water can be fast injected into the submerged arc furnace; and due to the fact that production does not need to be halted in the method, the furnace bottom of the submerged arc furnace can burst when meeting water at the high temperature, the furnace bottom settled layer is eliminated in time when just formed at the furnace bottom, or the formed settled layer is broken, and therefore the furnace bottom rising condition is avoided. The device and method are simple in structure, convenient to operate and beneficial to popularization.
Description
Technical field
The present invention relates to ore smelting technical field, more particularly to a kind of device for removing mineral hot furnace furnace bottom sedimentary and
Method.
Background technology
Smelting industrial silicon is swift and violent in China's development, and only the industrial silicon yield in 1 year 2016 whole nation is 2,400,000 tons.Industrial silicon
Manufacturing enterprise mainly uses mineral hot furnace.After mineral hot furnace is run through a period of time, often because feed particles size is improper, match somebody with somebody
Material composition proportion is improper, and secondary voltage is too high, the reason such as improper of smashing stove feeding operation, and accident, failure heating blowing-out number of times mistake
The factors such as many cause furnace bottom rising.Furnace bottom rising is primarily referred to as the non-fused mass in molten bath bottom and semi-molten thing sedimentary increases, and makes
Rise into melt silicon and reaction zone, melt silicon water can not unobstructedly flow out mineral hot furnace when going out silicon, while having a strong impact on stove inner capacities
Yield is caused to decline, power consumption increases.When using measures such as adjustment charge ratio, deep intercalative electrode depth furnace bottom rising can not be eliminated,
It is accomplished by stopping charging, carborundum in treatment furnace carries out the operations such as mineral hot furnace light maintenance, dry combustion method, prepurging.
For the phenomenon of furnace bottom rising, generally use blow furnace burdening up with dynamite at present, and this method high cost,
Consume big, have a strong impact on the production of enterprise.A fried stove needs the cycle of 1 to 2 months.So lasting high investment, causes enterprise
The production cost of industry can be in any more, or even because continual fryer results in a loss.It is stove by taking 6300KVA mineral hot furnaces as an example
Interior accumulation 50-60T furnace charges all dig out blow-on normally, need the time of 30 days, and stop production the loss of income for causing in addition, two phases
Plus up to more than 500,000 yuan.Simultaneously huge industrial silicon waste residue can be produced, because waste residue is to produce work caused by body of heater rise fryer
The main path of industry silicon waste residue, it is annual because the waste residue that fryer is produced is according to incompletely statistics more than 80 ten thousand tons.Industrial silicon waste residue
Solid waste is stored up do not only take up a large amount of soils for a long time, and can cause severe contamination and harm to water system and air.Greatly
The result that amount waste mining rock is piled up, has damaged the farmland and backwoods of sheet；The harmful slag of industrial silicon is stored up for a long time, through sleet
Leaching, soluble ingredient permeates downwards with water from earth's surface, to soil mobility conversion, is enriched with harmful substance, makes stockyard soil property acid nearby
Change, alkalize, harden. or even there is metal mold pollution.
As can be seen here, the above-mentioned existing method for removing mineral hot furnace furnace bottom sedimentary has obviously still suffered from inconvenience, and
Urgently it is further improved.How a kind of device and method of new removing mineral hot furnace furnace bottom sedimentary is founded so as to no
Produced with blowing out, simply and easily realize preventing the rising of mineral hot furnace furnace bottom sedimentary.
The content of the invention

Used as a modification of the present invention, the metal tube is iron pipe.
Further improve, a diameter of 0.2～1cm of the iron pipe.
Further improve, the gas cylinder is oxygen cylinder.
Further improve, the pressure of the oxygen cylinder is 1.2～1.5MPa.
Further improve, the length of the compression resistance leather hose is 0.5～1.0m.
Further improve, the mineral hot furnace is industrial silicon mineral hot furnace.
Present invention also offers a kind of method of the removing mineral hot furnace furnace bottom sedimentary of application said apparatus, methods described bag
Include following steps：
(1) one end that the metal tube is had high-temperaure coating puts in the ore deposit heat from the liquid outlet of mineral hot furnace furnace bottom
Furnace interior, its other end connects the compression resistance leather hose；
(2) gas outlet that its other end is connected to the gas cylinder after water is injected in the compression resistance leather hose；
(3) air outlet valve of the gas cylinder is opened, the air pressure of the gas cylinder is by the water in the compression resistance leather hose
In injecting the mineral hot furnace rapidly, then burst after furnace bottom high temperature chance water in the mineral hot furnace, realize to the mineral hot furnace stove
The removing of bottom sediments layer.
Further improve, sedimentary of the water injection rate of compression resistance leather hose according to the mineral hot furnace furnace bottom in the step (2)
Thickness is determined.
After such design, the present invention at least has advantages below：
The cooperation that the present invention passes through refractory metal pipe, compression resistance leather hose and gas cylinder, can realize quickly noting moisture content
Enter mineral hot furnace, due to the method and without stopping production, the mineral hot furnace furnace bottom has high temperature silicon liquid, and high temperature silicon liquid meets water can be occurred
Explosion so as to removed in time when furnace bottom just will form furnace bottom silicon, or the sedimentary to having been formed ruptures,
So as to the situation for preventing furnace bottom rising occurs.
Present configuration is simple and convenient to operate, beneficial to popularization.
