Description

A kind of electric heating rotary renewable stove

The utility model relates to the Industrial Stoves class, particularly a kind of electric heating rotary renewable stove.

China introduces the eighties and has digested carbon slurry process, development along with the gold industry, the carbon pulp factory of building also increases gradually, the gac that carbon pulp factory is used is behind the running certain hour, its adsorptive power will descend, and influence is to the recovery of gold, when wet reclamation is invalid, then need pyrogenic process regeneration, electric heating rotary renewable stove is pyrogenic process regenerated equipment; The electrothermic type activated carbon regeneration furnace can be divided into two kinds of external-heat and internal heat types by type of heating, at present, the internal heat type regeneratory furnace of industrial use, the position of its heating electrode and the mode of motion of charcoal are different, so its performance also has bigger difference; Regeneratory furnace according to the manufacturing of Chinese patent ZL8510061.9 technology, its heating electrode is installed in intravital two sides of cone shape process furnace, belong to the intermittent type regeneratory furnace, in the cone of earlier charcoal being packed into before each regeneration, with vibrating motor the intravital charcoal layer of awl is vibrated then, the direct current that between two electrodes of its both sides, adds 135V-220V, charcoal layer as conductor produces heat under the effect of electric current, in more than 10 minutes time self is being heated to about 800 ℃, reach the regenerated purpose, the regenerated charcoal draws off from the cone bottom, prepares to regenerate next time again; Activated carbon regeneration furnace by the manufacturing of ZL9620904.6 patented technology is a kind of horizontal chamber oven, furnace chamber is the rectangular body that certain inclination angle is arranged, charcoal adds the furnace chamber from the higher end of furnace chamber continuously, the paired heating electrode of many groups is vertically mounted on the both sides of body of heater, vibrating motor is established in the body of heater bottom, charcoal is evenly distributed in the furnace chamber also constantly to move to the furnace chamber rear portion, the charcoal layer bears the voltage of 60V-110V between each counter electrode, electric current produces heat by the charcoal layer, therefore when charcoal moves to the furnace chamber rear portion, be heated to about 800 ℃, reach the regenerated purpose, from stove, discharge; Vertical regeneratory furnace is a vertical rectangle cavity, and many counter electrode are installed in the cavity both sides, is equivalent to horizontal regeneratory furnace erected install, and charcoal adds from top, discharges the regenerated charcoal in the furnace chamber bottom by the discharge machine; More than three kinds of regeneratory furnaces all have certain shortcoming, it at first is the intermittent type regeneratory furnace, because heat can not reuse, power consumption is big, generally reaches per kilogram gac 1.5-2.0Kw.h, because vibration and repeated start-stop constantly, unit failure rate height because charcoal layer temperature constantly raises, requires power supply that stronger automatic adjusting electric power function is arranged again, therefore higher to power requirement, the power unit cost is also high accordingly; Horizontal regeneratory furnace owing to can utilize regenerate back charcoal with a part of heat, power consumption drops to per kilogram gac 1Kw.h, but have the high and automatically controlled part functional defect of failure rate of machinery too, especially electrode distance is too small, because the resistance of charcoal layer increases with carbon layer, electrode distance is too small, easily cause the excessive problem such as electrode erosion that causes of electric current, equipment manufacturing cost is also high, because vibration row charcoal place powdered carbon dirt is big, severe operational environment, the charcoal wearing and tearing are big; Though vertical regeneratory furnace power consumption decreases, be about per kilogram gac 0.8Kw.h, failure rate of machinery is few, because the electrically heated form is with horizontal identical, the control panel complexity, the cost height, the electrical equipment problem still influences it and applies.

The purpose of this utility model is exactly the shortcomings that exist at above-mentioned three kinds of internal heat type activated carbon regeneration furnaces commonly used, and a kind of electric heating rotary renewable stove is provided, and makes it have quick heating, the body of heater volume is little, at the bottom of the cost, the life-span advantages of higher.

The technical solution of the utility model:

According to the purpose of this utility model, a kind of electric heating rotary renewable stove is provided, its furnace main body adopts the charcoal outer steel shell, built-in refractory materials, go out the charcoal passage a little less than advancing the charcoal passage, go out the charcoal passage and advance the charcoal passage and all adopt lagging material insulation, the furnace main body bottom adopts four beaming rollers to support, and realizes the body of heater rotation with chain gear; Adopt the refractory brick module into and out of the charcoal passage, its attitude is adjustable, puts Graphite Electrodes in module, goes out the charcoal passage and adopts tubular structure, and going out charcoal passage adding water vapour, and water vapour also plays cooling effect simultaneously, the whole adjustable angle of body of heater; Adopt packing seal between the lagging material of charcoal passage and body of heater, filler is high temperature materials such as graphite, asbestos; Gac add the thermal recovery silicon controlled rectifier, the Current Negative Three-Point Capacitance triggering circuit, this kind circuit can guarantee that heating power does not reduce to increase too fast because of gac resistance, output rating can be regulated, adopt temperature to control out charcoal, be that gac is when being heated to 700-800 ℃, begin charcoal, go out the charcoal amount and adopt the control of many group time relays, water vapour adding is simultaneously controlled by temperature also, after promptly arriving design temperature, water vapour begins to add in the gac, and body of heater rotation is and begins to add gac and carry out synchronously.
