Description
Technical field
The utility model relates to a kind of single phase ac calcium carbide stove, belongs to the equipment for preparing industrial calcium carbide.
Background technology
Furnace of calcium carbide is mainly used in the production of industrial calcium carbide, its primary structure comprises body of heater and is arranged at intravital three electrodes of stove, produces electric arc by after the electrifying electrodes during work, and the high temperature that forms by electric arc makes raw material generation reaction in the stove, generate calcium carbide, calcium carbide formation reaction equation is CaO+3C=CaC
2+ CO-111.3Kcal (1800 ℃～2200 ℃) is thermo-negative reaction, and in electrode was transferred to furnace of calcium carbide, electrode was converted into arc heat and resistance heat with electric energy by electric current for institute's heat requirement and temperature.Arc temperature reaches more than 3500 ℃, and temperature of reaction only needs 1800 ℃～2200 ℃, and unnecessary heat is taken away by the CO gas that produces.
Under the normal working of a furnace, material and liquid calcium carbide that electrode tip is melted state surround, in electric arc scope in one's power, a large amount of heat energy mainly are the forced convections by intensive thermal radiation, thermal conduction, liquid calcium carbide, and CO gas, C, Ca steam produces fierce the stirring etc. just in the molten bath of dissipation of heat below the electrode tip in the process of their effusion fusion phases, and some hear rate is in charge preheating simultaneously.At electrode tip, around center lines of electrodes about 1.5～2 times in the amplitude of electrode diameter, vertically expand to 2～4 times of degree of depth downwards from electrode end surface simultaneously to arc length, comprehensive this space forms highest temperature zone in the stove.The temperature distribution in stove Nei Ge district (giving the hot-zone, reaction zone, melting zone etc.) is uneven, and far away more along with leaving the center, temperature is also low more.
Traditional single phase ac calcium carbide stove, as shown in Figure 2, its structure formation is connected with a circular electrode for the circuit that whenever is coupled, it is every electrode that is mutually, be referred to as single-phase single electrode in the industry and exchange furnace of calcium carbide, three electrodes are equilateral triangle and are arranged in body of heater inside, and the body of heater shell is set to circle; Obviously, it is bigger that this single-phase single electrode exchanges the interior electrode power strength difference of furnace of calcium carbide, the thermal power skewness, cause body of heater internal temperature gradient bigger, thermosteresis is higher, in addition, conversion zone is also less relatively, comparatively speaking, also higher to the requirement of raw material, need raw material to have stronger adaptability; Easily produce branch current simultaneously, power consumption is more than 3300 degree/tons, and energy consumption is higher, and the exhaust temperature instability influences production operation in addition.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides a kind of heat distribution more even, and calcium carbide output is bigger, the furnace of calcium carbide that energy consumption is lower and reaction efficiency is higher.
The utility model has adopted following technical scheme:
A kind of single-phase multi-electrode exchanges furnace of calcium carbide, comprises body of heater and is positioned at the intravital three-phase electrode of stove, and described every phase electrode comprises the electrode more than two or two in parallel at least.
Wherein, the number of electrodes of described every phase electrode can equate or be unequal, the arrangement mode of every phase electrode can be identical or inequality, and the arrangement mode of every phase electrode is selected from rectangle, square, rhombus, circle or the trilateral arrangement mode of any one or any several combinations.
Preferred scheme is: the number of electrodes of every phase electrode equates, and the arrangement mode of every phase electrode is identical.
Most preferred scheme is: the quantity of every phase electrode is two in the described scheme, and the arrangement mode of three-phase electrode is equilateral triangle, and the arrangement mode of every phase electrode is rectangle.
The utility model has adopted the electrode of many parallel connections than prior art on the circuit that whenever is coupled, because number of electrodes increases, single electrode secondary current reduces, the zone, total molten bath of this electric furnace increases, and makes that the conversion zone in the furnace of calcium carbide increases greatly, thereby output is increased.Simultaneously because after adopting single-phase multi-electrode, the electric current of every electrode diminishes, the high-temperature zone tails off, the temperature distribution gradient diminishes, and heat distribution is more even, the corresponding minimizing of branch current, reduced thermosteresis, thereby reduced consumption, further improved the suitability of raw material, and then improved furnace of calcium carbide W-response efficient.
