Description
Technical field
The utility model relates to Vanadium Pentoxide in FLAKES production unit field, particularly relates to a kind of efficient yellow phosphorus burning still.
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.
Utility model content
In order to overcome above-mentioned technical problem of the prior art, the utility model provides a kind of efficient yellow phosphorus burning still, and this efficient yellow phosphorus burning still sprays with Sprayable after liquid phosphor being added to burning still, and long-pending large with air contact surfaces, reaction efficiency is high.
Concrete technical scheme of the present utility model is: a kind of efficient yellow phosphorus burning still, comprise burning kettle, the top of described burning kettle is provided with yellow phosphorus filling tube, burning kettle outer wall bottom is provided with intake ducting, the bottom of described yellow phosphorus filling tube is provided with humidifier, described intake ducting is coil-like, described intake ducting is evenly distributed with production well, described burning kettle inside is also provided with condensation pipe, the inlet mouth position of described condensation pipe is lower than the air outlet of condensation pipe, and described inlet mouth runs through the sidewall of burning kettle, the roof of burning kettle is run through in described air outlet, the bottom of burning kettle is also provided with material taking mouth.
In the utility model, after the yellow phosphorus of molten state enters yellow phosphorus filling tube, add in burning kettle through humidifier with Sprayable; On the other hand, after air enters intake ducting, because intake ducting is coil-like distribution, air enters burning kettle from production well and is uniformly distributed in burning kettle; So, in the yellow phosphorus of droplet shape and the contact area of air obtain and increase significantly, reaction efficiency is higher.
Simultaneously, due to the existence of condensation pipe, the freezing air in the burning kettle external world enters through inlet mouth, discharge from air outlet after flowing through condensation pipe, in the process, freezing air absorbs the amount of heat in burning kettle, continues to rising, and freezing air sucks from inlet mouth, define air cycle circulation.The heat of the Vanadium Pentoxide in FLAKES of the gaseous state of the generation in burning kettle is absorbed, and becomes solid, fall into burning autoclave body bottom after burning kettle top cools gradually.The material taking mouth of burning kettle can be opened, and carries out feeding.
Further, described humidifier position is higher than the inlet mouth position of described condensation pipe, and the inlet mouth position of condensation pipe is higher than the position of intake ducting.
Further, described condensation pipe inlet mouth place part is the pipeline of horizontal positioned, and air outlet parts is the pipeline vertically arranged, and the pipeline of horizontal positioned is communicated with the many pipelines vertically arranged.
Further, described condensation pipe is the helical pipe vertically placed.Helical pipe can extend the runner of freezing air in burning kettle, thus the more heats of absorption.
Further, the bottom of described burning kettle is inverted cone-shaped.Inverted cone-shaped is convenient to the collection of solid-state Vanadium Pentoxide in FLAKES.
Be compared with the prior art, the beneficial effects of the utility model are: efficient yellow phosphorus burning still of the present utility model sprays with Sprayable after liquid phosphor being added to burning still, and long-pending large with air contact surfaces, reaction efficiency is high.The Vanadium Pentoxide in FLAKES of generation can cool by the setting of condensation pipe fast, becomes solid-state.
