Description
Technical field
The utility model relates to a kind of ventilating systems, and in particular to a kind of acheson furnace furnace bottom ventilating system.
Background technique
Acheson furnace is the furnace body of electric heating engineering method heating purification graphite products, first has to produce in a furnace in production
Product are discharged the impurity in product in furnace, so that the phosphorus content of product is reached 99.98% or more, adding to 2800-3000 degrees Celsius
After the completion of heat, needs to cool down to furnace body and product, take out finished product in furnace.
Furnace bottom is built into for high-alumina brick, and high-alumina brick can be 1700 degrees Celsius with high temperature resistant, but in-furnace temperature can achieve 3000 and take the photograph
Family name's degree, although furnace bottom high-alumina brick and furnace high-temperature area have 70 centimeters of carbon black thermal insulation layer, in-furnace temperature can gradually pass to furnace bottom height
Aluminium brick, high-alumina brick temperature can be gradually more than 1700 degrees Celsius, and high temperature can be such that the conductivity of carbon black thermal insulation layer increases, and on the one hand waste
Electric energy, on the other hand will be greatly reduced the service life of furnace bottom high-alumina brick, therefore will be greatly reduced making for acheson furnace
Use the service life.
In process of production, sulfur dioxide can be discharged, coal gas etc. is flammable in acheson graphite high temperature furnace during high temperature impurities removal
In property gas to furnace bottom space, temperature can achieve 1000 degrees Celsius or more in furnace bottom, therefore can be imflammable gas in furnace bottom
It ignites, after the oxygen mix in furnace bottom in imflammable gas and its air reaches a certain concentration, can also explode under high temperature action,
Therefore totally unfavorable to production and safety.
Utility model content
Sulfur dioxide can be discharged in order to solve acheson graphite high temperature furnace furnace bottom during high temperature impurities removal in the utility model
With the imflammable gas such as coal gas, it can explode under high temperature action and furnace bottom high temperature can reduce acheson furnace and use the longevity
The problem of life, and a kind of acheson furnace furnace bottom ventilating system is provided.
The utility model adopts the technical scheme that solve above-mentioned technical problem：
It includes inert gas air accumulator, regulating valve, purifying column and multiple channels；
The bottom of furnace body is arranged in multiple channels, and the entrance in each channel is connected to by pipeline with inert gas air accumulator,
And the inlet in each channel is equipped with regulating valve, the outlet in each channel is connected by pipeline with purifying column.
The utility model has the advantages that compared with prior art：
One, inert gas air accumulator is arranged in the utility model to be connected to multiple channels, is released by inert gas air accumulator
It puts inert gas to take away the heat of furnace bottom, reduces the temperature of furnace bottom, reduce furnace bottom carbon black thermal insulation layer conductivity, save big
Electric energy is measured, the turnover rate of furnace bottom carbon black thermal insulation layer is reduced, the fuel gas of furnace bottom is discharged, last fuel gas passes through purifying column
It collects, prevents pollution air.
Two, the utility model is passed through the use longevity that inert gas improves acheson furnace to furnace bottom cooling in furnace bottom
Life, makes the service life of acheson furnace increase 10-15 furnace.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
Specific embodiment one：Illustrate present embodiment in conjunction with Fig. 1, present embodiment it include inert gas air accumulator
1, regulating valve 2, purifying column 4 and multiple channels 5；
The bottom of furnace body is arranged in multiple channels 5, and the entrance in each channel is connected by pipeline and inert gas air accumulator 1
It is logical, and the inlet in each channel is equipped with regulating valve 2, the outlet in each channel is connected by pipeline with purifying column 4.
Filled with nitrogen in the inert gas air accumulator 1, cannot be followed using air when heat is discharged using protective gas
Ring discharge, it is necessary to be filled with inert gas in the channel, and the 75% of nitrogen duty gas, i.e., good acquisition environmental sound again reduces
Cost.
Specific embodiment two：Illustrate present embodiment in conjunction with Fig. 1, regulating valve 2 described in present embodiment is temperature control tune
Air valve.
Other compositions and connection relationship are same as the specific embodiment one.
Specific embodiment three：Illustrate present embodiment in conjunction with Fig. 1, each channel 5 of present embodiment it is neighbouring enter
The position of mouth and neighbouring outlet is equipped with temperature sensor 3, and the temperature control Air-regulating valves are connect by conducting wire with temperature sensor 3.
The position of each 5 neighboring entry of the channel and neighbouring outlet is equipped with the air output that temperature sensor 3 controls furnace bottom
With the time of supplying gas, when bottom temperature is low, regulating valve 2 corresponding with each channel 5 controls inert gas air accumulator 1 and is passed into
The air output in corresponding channel 5 keeps the air output in corresponding channel 5 smaller；When bottom temperature is high, with each channel 5
Corresponding regulating valve 2 controls the air output that inert gas air accumulator 1 is passed into corresponding channel 5, makes corresponding channel 5
Air output it is larger, not only reduced the temperature of furnace bottom in this way, but also effectively eliminate the inflammable gas of furnace bottom.
Specific embodiment four：Illustrate present embodiment in conjunction with Fig. 1, each channel of present embodiment 5 is by furnace body
The wall 6 of internal multiple interlaced arrangements forms folding shape or S-shaped channel.
Present embodiment makes pernicious gas that the bottom of furnace body more effectively be discharged.
Specific embodiment five：Illustrate present embodiment in conjunction with Fig. 1, each wall 6 of present embodiment it is a height of
120mm。
