Description
Technical field
The utility model relates to Vanadium Pentoxide in FLAKES production unit field, particularly relates to a kind of Vanadium Pentoxide in FLAKES production unit of efficient energy-saving.
Background technology
Vanadium Pentoxide in FLAKES is raw material conventional in chemical industry and reagent, is widely used in each field.The preparation of current industrial Vanadium Pentoxide in FLAKES is generally adopt oxidative combustion: take yellow phosphorus as starting material, roasting kiln is added by after yellow phosphorus heat fused, pass in roasting kiln and carry out reactive combustion through the air of drying treatment and yellow phosphorus, generate Vanadium Pentoxide in FLAKES flue gas, again Vanadium Pentoxide in FLAKES flue gas is cooled, make Vanadium Pentoxide in FLAKES finished product.
The weak point of existing production technique is, is reacted into Vanadium Pentoxide in FLAKES by adding to after yellow phosphorus heating and melting in burning still with air combustion again.The contact area of liquid phosphor and air in still of burning in prior art is less, causes reaction efficiency not high enough.
Meanwhile, after yellow phosphorus and air combustion, generate a large amount of heats, not only cause the Vanadium Pentoxide in FLAKES generated cannot rapid condensation, but also cause energy dissipation.
Utility model content
In order to overcome above-mentioned technical problem of the prior art, the utility model provides a kind of Vanadium Pentoxide in FLAKES production unit of efficient energy-saving, and the heat after this equipment can utilize Vanadium Pentoxide in FLAKES to generate, to heat yellow phosphorus, makes yellow phosphorus melting, energy-saving and emission-reduction; After liquid phosphor adds combustion reactions still to Sprayable simultaneously, long-pending large with air contact surfaces, reaction efficiency is high.
Concrete technical scheme of the present utility model is: a kind of Vanadium Pentoxide in FLAKES production unit of efficient energy-saving, comprises combustion reactions still, yellow phosphorus hold-up vessel.The bottom of described yellow phosphorus hold-up vessel is connected with feeding tube; Top in described combustion reactions still is provided with humidifier, and the upper end of described humidifier is communicated with described feeding tube; Combustion reactions still outer wall bottom is connected with air line, and described air line is coil-like, and air line is evenly distributed with air dispelling hole;
Combustion reactions still outer wall top is also provided with gas exhaust duct, and the outer wall of yellow phosphorus hold-up vessel is also provided with water back, and the lower end of described water back is communicated with described gas exhaust duct; The Vanadium Pentoxide in FLAKES production unit of described efficient energy-saving also comprises Vanadium Pentoxide in FLAKES hold-up vessel, and pipeline communication is passed through at the upper end of water back and the top of described Vanadium Pentoxide in FLAKES hold-up vessel.
In the utility model, yellow phosphorus enters into combustion reactions still in through humidifier with droplet form by feeding tube, after air enters air line, because air line is coil-like distribution, air enters burning kettle from air dispelling hole and is uniformly distributed in combustion reactions still.So, the contact area of droplet shape yellow phosphorus and air obtains and increases significantly, and after mixing, reaction efficiency is higher.
Simultaneously, the Vanadium Pentoxide in FLAKES of the gaseous state after generation is discharged from gas exhaust duct, enter water back, because water back and yellow phosphorus hold-up vessel are close to, in the process, yellow phosphorus absorbs the amount of heat of Vanadium Pentoxide in FLAKES and melted by heating, and the heat of the Vanadium Pentoxide in FLAKES of gaseous state is absorbed, solid is become after cooling after entering five heats of oxidation pouring hold-up vessels, thus obtained finished product.
As preferably, on described feeding tube, on gas exhaust duct, the pipeline at Vanadium Pentoxide in FLAKES hold-up vessel top is provided with pump and valve all separately.
As preferably, described water back is helical pipe.Helical pipe can extend Vanadium Pentoxide in FLAKES and yellow phosphorus hold-up vessel duration of contact, thus the more heats of release.
As preferably, in described yellow phosphorus hold-up vessel, be provided with whipping appts.
As preferably, described Vanadium Pentoxide in FLAKES hold-up vessel sidewall is provided with monitor window.
Be compared with the prior art, the beneficial effects of the utility model are: the heat after this equipment can utilize Vanadium Pentoxide in FLAKES to generate, to heat yellow phosphorus, makes yellow phosphorus melting, energy-saving and emission-reduction; After liquid phosphor adds combustion reactions still to Sprayable simultaneously, long-pending large with air contact surfaces, reaction efficiency is high.
