Background technology
Ammonium vanadate comprises ammonium meta-vanadate (NH
4VO
3) or ammonium poly-vanadate (APV), produce Vanadium Pentoxide in FLAKES (V through the calcining deamination
2O
5) be an important procedure in the metallurgical whole process of vanadium.Obtain the powdery Vanadium Pentoxide in FLAKES from ammonium meta-vanadate or ammonium poly-vanadate and generally will pass through dehydration, deamination, three steps of oxidation insulation.In Vanadium Pentoxide in FLAKES Industrial processes in the past, what domestic vanadium factory adopted substantially is to build the box-type furnace of system with refractory brick or clay brick, well heater is the pure resistance silk, this tile stove distortion is big, poor sealing performance, cause the firing time long (general more than 72 hours), unit power consumption (is generally 1200～1400KWh/ ton V greatly
2O
5), ammonia leakage is serious, and neither environmental protection is also dangerous, and the rate of recovery is generally less than 99%, the product color instability.Utility model patent (CN201458771u) has designed the box deamination stove of stainless steel, adopts the heating of stainless steel electrothermal tube, the aluminium silicate wool insulation, solved the drawback of brick stove processed, heat insulation effect improves greatly, and the firing time shortens to 13～19 hours, and power consumption drops to 760KWh/ ton V
2O
5, set up the ammonia recovery tower simultaneously, solve ammonia effectively and reclaimed problem, reduced production cost, accomplished energy-conserving and environment-protective.But production process still is unrealized continuously, still is in the batch production state, and automatization level is low, and turnout very much not gets up, and does not still satisfy large-scale production.Though have three sections method of fusion to produce this kind equipment of Vanadium Pentoxide in FLAKES at present, have that facility investment is big, a complex structure, operation link is many, work production is low defective abroad.
Summary of the invention
So the purpose of this utility model is to provide, and a kind of structure is comparatively simple, easy to operate, production is continuous, ammonium vanadate energy-conserving and environment-protective are produced the full-automatic deamination stove of Vanadium Pentoxide in FLAKES.
In order to solve above-mentioned technological deficiency, a kind of ammonium vanadate provided by the utility model is produced the deamination stove of Vanadium Pentoxide in FLAKES, it is characterized in that it comprises: tunnel type furnace body, charging tray, charging tray driving chain, chain guide, heating tube, temperature conduction device, vapor pipe, resting support; Described tunnel type furnace body is divided into three districts: drying zone, deamination district, heat preservation zone, and the top evenly is provided with heating tube in described three districts, and subregion arranges the temperature conduction device; The diapire both sides are provided with chain guide in the tunnel type furnace body, and the charging tray driving chain places on the chain guide by the rotor wheel at two ends, and charging tray one side active card is between the charging tray driving chain; The outer top of each subregion of described tunnel type furnace body is equipped with vapor pipe; Described tunnel type furnace body is by the resting support fixed support.
Described heating tube is far-infrared heating tube or microwave device.
Described charging tray driving chain drive line speed is 5～12m/h.
Described tunnel type furnace body opening for feed one side is provided with an automatic charge device.
Described tunnel type furnace body burner hearth wall is equipped with the heat-resistant light insulating cotton.
The number of described each subregion vapor pipe, temperature conduction device is decided according to the design length of each subregion, and general interval arranges one for 5 meters.
Its basic functional principle is: ammonium meta-vanadate or ammonium poly-vanadate are in automatic charge device branch is packed the stainless steel charging tray into, charging tray slowly moves in tunnel type furnace body with the linear velocity of 5～13m/h by chain, dewater under 120～200 ℃ of temperature through drying zone earlier, water vapor is discharged by vapor pipe, about 2～3h of time; After the dehydration, charging tray has entered the deamination district, carries out deamination under 210～550 ℃ of temperature, and ammonia is sent into the ammonia retrieving arrangement of establishing in addition by vapor pipe and variable valve and reclaimed, and the deamination time is 5～6h; Ammonia enters the insulation oxidation zone after taking off and finishing, be arranged on 300～80 ℃ in this district's temperature, form gradually cold state, strengthen the inlet of air simultaneously, assurance oxygen abundance, oxidation is abundant, about 2～3h of time, at this moment charging tray has moved to discharge end, and the ammonium vanadate in the charging tray has been produced the powdery Vanadium Pentoxide in FLAKES of yellowish-orange; Finished product along with the upset of charging tray, is poured in the storage bunker in charging tray automatically in operational process, and empty charging tray continues to be circulated to loading area.Burner hearth adds thermal recovery far-infrared heating tube or microwave device and carries out the penetrating type heating, and temperature control is by circuit of SCR control, temperature error ± 3 ℃; Body of heater carries out the four sides insulation by aluminium silicate wool; Transmission system is dragged by variable-frequency motor, can realize the stepless change transmission.The length of each subregion is determined by the time according to the raw material that arranges in the tunnel type furnace body, and the length in general deamination district is greater than the length of drying zone and heat preservation zone.
Beneficial effect: the utility model structure is comparatively simple, efficient, high, the safety and environmental protection, energy-conservation, anticorrosion durable of level of automation.The time of coming out of the stove is 9～13h, ton V
2O
5Power consumption is 650～700kWh, produces continuously, and output is big, and full burner hearth carries out constant product quality in the aerobic atmosphere of abundance.
