Abstract
The invention discloses a method for producing an anode butt by adopting energy saving and environment protection technologies. A roasted anode butt blank block is conveyed into a ring-type roasting furnace, coal gas serves as fuel, and through slow temperature rise, heating to high temperature, cooling and discharging, a fired anode butt green-pressing block is obtained and is made into a polyhedral cracked block (namely the anode butt). In the roasting process, smoke discharged out of the roasting furnace enters a purifying system to be subjected to purifying treatment. Heat generated when the anode butt blank block is roasted in the ring-type roasting furnace is fully utilized, thermal efficiency is high, continuous production is achieved, the yield is high, and product quality is stable. The smoke discharged to the atmosphere is fully purified, and the environment is protected. In a word, the method saves energy, is environmentally friendly, and caters to the current national industry and enterprise development guidelines of energy saving and emission reduction, consumption reduction and efficiency increasing and environment protection.
Description
One, technical field
What the present invention relates to is a kind of broken method of anode of producing, and especially a kind of applicating energy-saving green technology is produced the broken method of anode.
Two, background technology
Anode is broken as metallurgy industry blast furnace ironmaking raw material, the deep processing raw material of carbon goods industry, the reducing agent of chemical industry etc., and existing market is in great demand.Current, China produces the broken enterprise of anode, and the stove majority of the baked article of application is downward flame calcining kiln.Downward flame calcining kiln be take fire coal as thermal source through cooking stove fire jetting hole to kiln top quirk flame, flame flows along quirk from top to bottom, by quirk, pass to goods and the inserts in firing chamber, through furnace bottom, be communicated with quirk and enter branch flue, by flue collector, enter chimney and enter atmosphere.Downward flame calcining kiln belongs to gap production operation equipment, be each independently firing chamber from goods shove charge, all to adopt independently direct combustion coal mode to heat up, be heated to high temperature, insulation, and then lower the temperature lentamente, when furnace temperature drops to 60 ℃, goods can be come out of the stove, and after normal temperature, to obtain anode broken for broken clamp dog.Apply this kind of method production anode broken, consume energy high, the thermal efficiency is low, single kiln production capacity is low, labour intensity is large, severe operational environment, contains the pernicious gases such as carbon dioxide, pitch coal tar, sulfur dioxide in flue gas, directly from chimney, enter atmosphere serious environment pollution.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the object of this invention is to provide a kind of applicating energy-saving green technology and produce the broken method of anode.
The technical scheme that realizes object employing of the present invention is: a kind of applicating energy-saving green technology is produced the broken method of anode, its production process is: the broken green briquette of the baked anode of making piece is sent into ring-form calcining furnace, with coal gas as fuel, through heating up lentamente, heating, high temperature, cooling, obtain Anode briquet after coming out of the stove; In baked anode green briquette process, the baking flue gas that contains tar and dust of discharging from roaster enters cleaning system and carries out purified treatment; Anode briquet passed through to machinery or manually makes the irregular polyhedron fragment of all kinds of specifications, can obtain anode broken, through test package, just can sell to client.
Described ring-form calcining furnace, is comprised of 26 identical roasting furnace chambers of structure, and each furnace chamber has 3 roasting hoppers; Adjacent two furnace chambers are end to end, and the flue gas that high temperature furnace chamber is discharged enters the adjacent furnace chamber broken green briquette of baked anode of heating, and combustion flame is together in series and forms ring type heating at full stove.
Described baking flue gas enters cleaning system and processes, that flue gas is pooled to after flue collector, introduce automatic spray humid cabinet flue gas is cooling, make again flue gas enter electrical tar precipitator, electrical tar precipitator gathers dust the tar in flue gas, dust catching on precipitation pole plate to electricity, and the tar trapping on pole plate focuses in oil pooling dipper and regularly reclaims by the vertical underflow of deadweight.
The invention has the beneficial effects as follows: the one, ring-form calcining furnace be applied in the broken green briquette of baked anode time, calory burning is fully used, the thermal efficiency is high, production is continuous, output is high, sintering temperature regulate with control convenient, constant product quality.The 2nd, by the application of flue gas purification system, baking flue gas is carried out to purified treatment, the flue gas that makes to enter in atmosphere is purified fully, has protected environment.In a word, application production efficiency of the present invention is high, and good work environment is both energy-conservation, and environmental protection again meets that current national Energy Saving in Industrial Enterprises reduces discharging, the developing policy of consumption reduction synergy, protection of the environment.
Four, the specific embodiment
A kind of applicating energy-saving green technology is produced the broken method of anode, its production process is: the broken green briquette of the baked anode of making piece is sent into ring-form calcining furnace, with coal gas as fuel, through heating up lentamente, heating, high temperature, cooling, obtain Anode briquet after coming out of the stove; In baked anode green briquette process, the baking flue gas that contains tar and dust of discharging from roaster enters cleaning system and carries out purified treatment; Anode briquet passed through to machinery or manually makes the irregular polyhedron fragment of all kinds of specifications, can obtain anode broken, through test package, just can sell to client.
Described ring-form calcining furnace, is comprised of 26 identical roasting furnace chambers of structure, and each furnace chamber has 3 roasting hoppers; Adjacent two furnace chambers are end to end, and the flue gas that high temperature furnace chamber is discharged enters the adjacent furnace chamber baked anode green briquette of heating, and combustion flame is together in series and forms ring type heating at full stove.Calory burning is fully used, and the thermal efficiency is high, and production is continuous, and output is high, and sintering temperature regulates and controls conveniently constant product quality.
Described baking flue gas enters cleaning system and processes, and is flue gas is pooled to after flue collector, introduces automatic spray humid cabinet flue gas is cooling, guarantees that flue-gas temperature is all the time between 80 ℃～135 ℃, can Yin Wendu superelevation and cause that inner flue gas catches fire.Flue gas enters in electrical tar precipitator, and electrical tar precipitator gathers dust the tar in flue gas, dust catching on precipitation pole plate to electricity, and the tar trapping on pole plate focuses in oil pooling dipper and regularly reclaims by the vertical underflow of deadweight.The flue gas that makes to enter in atmosphere is purified fully, has protected environment.
Adopt new, old production technology to produce the broken technical-economic index of anode according to table
