Description
Technical field
The present invention relates to a kind of carbide production field, specifically a kind of acetylene stones sensible heat is reclaimed and exempts from breaker.
Background technology
The operation of all carbide manufacturing enterprises is all at present；The molten state carbide come out of the stove from electric furnace is flowed into resistant to elevated temperatures electricity
Stone pot, molten state carbide carry out natural cooling where being pulled to car in calcium carbide pot necessarily, after carbide solidification, use overhead crane
Carbide stone roller is hung out, is placed on cast iron ground and is cooled down, carbide is crushed to into release mesh after being cooled to appropriateness, is then graded grading
Row packaging, sends into warehouse for finished product.Electric furnace flows into the molten state carbide temperature of calcium carbide pot more than 1600 degree, in natural cooling process
In, substantial amounts of heat energy (including sensible heat and the heat of transformation) will be released.By this partial heat energy is calculated, carbide about 700kWh per ton is produced,
224kg standard coals are closed, heat loss is, than larger, to account for more than the 24% of power consumption of calcium carbide.This partial heat energy is never utilized, electricity
Carbide is crushed to into release mesh after stone stone roller solidification, often stone roller carbide is nearly one ton heavy, and it is not easy that will be broken into certain small grain size
Thing, high labor intensive, dust atmosphere pollution, crushing mechanism device damage is serious.Consume a large amount of manpowers and material loss.
The content of the invention
It is an object of the present invention to provide one kind does not change carbide production technology, and simply from the beginning of electric furnace discharging, molten state electricity
After rock glacier enters calcium carbide pot, be transported to apparatus of the present invention and complete energy recovery and cool down carbide bag to be delivered directly to uniform temperature
The acetylene stones sensible heat of dress operation is reclaimed and exempts from breaker.
The present invention solves technical problem and provides following scheme：
A kind of acetylene stones sensible heat is reclaimed and exempts from breaker, including body of heater, it is characterised in that：The left and right two ends difference of the body of heater
Hot-blast outlet and cold air air inlet are provided with, the hot-blast outlet connects hot air duct, in the body of heater, are provided with chain-plate type conveying
Mechanism, the upper surface that the chain and pan conveyor structure has chain-plate type conveyer belt, the chain-plate type conveyer belt are provided with carbide molding
Mould, the top left end of the body of heater are provided with melting furnace of calcium carbide, and there is body of heater the lower section of the melting furnace of calcium carbide by channel connection
Inner chamber, the carbide of the melt are dropped in carbide mould downwards by passage, then along chain and pan conveyor structure to cold sky
One lateral movement of gas air inlet, is provided with splicing groove below the cold cavity air inlet end of the chain and pan conveyor structure.
The inside of the body of heater is divided into high-temperature region and low-temperature space from hot-blast outlet to inlet of cold air.
The melting furnace of calcium carbide outer layer spraying high temperature thermal insulation coatings.
Apparatus of the present invention are；In calcium carbide pot, molten state carbide pours the special feed arrangement of heat exchange furnace upper end into, according to a constant speed
Degree is flowed in the high-temperature resistance die in recuperative furnace, and the mould in recuperative furnace is slowly moved from high-temperature region to low-temperature space, while heat exchange
In stove, diverse location has air-cooled air-flow, move to certain position cooled and solidified, now mould reversed blanking, the electricity of high temperature coagulation
Stone is sent to next heat-exchanger rig, is delivered directly to packaging process when carbide temperature drops to a timing.Whole process can both be returned
Receive more than 50% sensible heat heat energy, again can in case arrive broken process.Reducing energy consumption, reduces production cost, reduces dust pollution, changes
Kind production environment.
Apparatus of the present invention do not change carbide production technology, and simply from the beginning of electric furnace discharging, molten state carbide flows into calcium carbide pot
Afterwards, it is transported to apparatus of the present invention to complete energy recovery and cool down carbide to be delivered directly to packaging process to uniform temperature.
One；The capacity of typically all one ton of the calcium carbide pot of present carbide manufacturer, application claims add calcium carbide pot
Greatly to more than 5 tons, concrete how many tons will be determined according to furnace power.Calcium carbide pot outer layer spraying high temperature thermal insulation coatings, reduce heat
The loss of energy.Carbide pot bottom has special feed opening.
Two；From calcium carbide pot feed opening by on-off control, molten state carbide is flowed in heat exchange furnace interior mould, and mould is adopted
With resistance to more than 1600 degree cast steel materials.Have inside recuperative furnace；Mould transmission device, mould can be with the adjustable conveyer belt of rotating speed
Move from high-temperature region to low-temperature space, the demoulding blanking by temperature is dropped to below 100 degree, then be transported to packaging process.
Annual carbide production capacity increased ten thousand tons of 250-300 compared with last year within 2013.As large-scale furnace of calcium carbide sustained production is stablized
Increase, and blow-on is still being stablized in little furnace of calcium carbide part, so carbide yield in 2013 continues to increase, it is contemplated that annual production will exceed
22000000 tons, create a high position since the dawn of human civilization.2013 annual production of ferroalloy reaches 35,000,000 tons of carbide yield 22,000,000 in 2013
Ton, 35,000,000 tons of ferroalloy yield add up to 57,000,000 tons.About 2000 degree of high-temperature fusion electricity that acetylene stones sensible heat per ton is flowed out from electric furnace
Stone, in the natural cooling process after coming out of the stove, will release substantial amounts of heat energy (including sensible heat and the heat of transformation).It is hot by this part is calculated
Can, carbide per ton about 700kWh closes 224kg standard coals, and heat loss is than larger.
The inventive technique is adopted according to national 50% enterprise, only sensible heat one can save electricity=57,000,000 ton X350 degree
（According to 50% sensible heat heat energy of recovery）=1,995,000 ten thousand degree of nearly 20,000,000,000 degree of electric energy.
In addition, due to crushing, dust pollution is reduced, saves a large amount of work personnel, improve production environment, dropped
Low labor intensity, substantially reduces carbide production cost.
The similarly suitable ferroalloy production of above invention device.
