Description
Technical field
The utility model relates to a kind of stibium trioxide furnace gas phase equipment of crystallisation by cooling, particularly a kind of stibium trioxide furnace gas phase equipment of crystallisation by cooling.
Background technology
Because Antimony Trioxide: 99.5Min is of many uses, relate to industries such as enamel, pigment, paint, plastics, glass, papermaking, fire retardant, and every profession and trade is different to the performance requriements of weisspiessglanz.Under the more and more thinner trend of specialization, the downstream client is to the also more and more refinement of demand of Antimony Trioxide: 99.5Min, particularly require aspect the granularity of Antimony Trioxide: 99.5Min and the whiteness strict more.
At present, the production of Antimony Trioxide: 99.5Min mainly contains two kinds of wet method and pyrogenic processes, owing to pyrogenic process is compared with wet method and had that production technique is simple, output is high, low cost and other advantages receives widespread use.The antimony trioxide production technique is divided into pyrogenic process direct method and pyrogenic process indirect method again.The pyrogenic process indirect method uses star metal as raw material, obtains purified Antimony Trioxide: 99.5Min product through fusing, voloxidation, step such as sharply cool off, gather dust.During antimony trioxide was produced, the type of furnace, voloxidation technology and quench crystallization device etc. were the principal elements that influences quality product, and wherein, the quench crystallization device has key influence to performance index such as the whiteness of Antimony Trioxide: 99.5Min product, granularity, acid non-soluble substances.
Some open source literatures have been reported some equipment of crystallisation by cooling of preparation in recent years, but for example all have certain defective:
1, Chinese patent, application number: CN201010291833.X, the applying date: 2010.09.26 title: sodium aluminate solution crystallization reaction device, summary: a kind of sodium aluminate solution crystallization reaction device belongs to decomposition crystallization reaction device; Aim to provide a kind of being convenient to and make, can improve the supersaturated sodium aluminate solution crystallization reaction device of crystalline aluminum hydroxide granularity.It comprises extraction line, the stir shaft that is connected with speed reduction that the top is fixed with the decomposer of phonomoter and speed reduction, is located at discharging chute in the decomposer, is communicated with this discharging chute, be located at and carry the material airduct in the extraction line; The aggregate tube and the extraction line that are fixed on the stir shaft flexibly connect, and there is paddle the bottom of aggregate tube, and there is the feed-pipe that is communicated with aggregate tube the top of this paddle, is distributed with some feed ports on this feed-pipe; Be provided with sealing element between aggregate tube and the extraction line.But the structure relative complex that should invent is not easy volume production and is used in the middle of the enterprise.
2, Chinese patent; Application number: the CN201110197038.9 applying date: 2011.07.14 title: a kind of absorption chemical energy storage equipment of crystalline that contains; Summary: a kind of absorption chemical energy storage equipment of crystalline that contains comprises producer, resorber, vaporizer, condensing surface, throttling valve, solution pump, strong solution storage tank, dilute solution storage tank, gas-liquid heat exchanger and refrigeration agent storage tank etc.The inside of said strong solution storage tank is provided with solution heat transfer tube and spiral coil cooling tube, and outer bypass one anti-crystallinic pipe of described solution heat transfer tube is used to dissolve crystal.The energy storage equipment that the present invention proposes; Being about to sun power, industrial exhaust heat, plentiful electric weight etc. is converted into chemical energy and stores; Improve the space of source and user side, the not matching property of T/A; But the device that this application needs is too complicated, and cost of manufacture is higher, can't understand crystallisation stage crystalline temperature simultaneously.
This just needs a kind of cost of manufacture low, and Antimony Trioxide: 99.5Min that simultaneously can the crystallization control temperature prepares equipment, to solve the above problems.
Summary of the invention
The order of the utility model provides a kind of stibium trioxide furnace gas phase equipment of crystallisation by cooling, overcomes capacity consumption height in the prior art, the insufficient shortcoming of producing of Antimony Trioxide: 99.5Min purity; Reach the reduction equipment cost; Increase equipment life, it is high to improve product purity, and low purpose reduces production costs.
The scheme of the utility model is through such realization: a kind of stibium trioxide furnace gas phase equipment of crystallisation by cooling; Comprise stibium trioxide stove, reactor drum, mold and crystal transport pipe; Said stibium trioxide stove, reactor drum, mold and crystal transport pipe are connected successively; Wherein an end of reactor drum stretches in the stibium trioxide stove, it is characterized in that: but said mold interior wall is provided with horizontal folding round mouth.
The principle of work of the utility model is following: Antimony Metal 99.65& 99.96 is after the stibium trioxide stove becomes the Antimony Trioxide: 99.5Min furnace gas through voloxidation; It is imported continuation reaction in the reaction chamber; Subsequently, the Antimony Trioxide: 99.5Min furnace gas is imported in the mold, but through in the folding round mouth, blasting cold wind; Make Antimony Trioxide: 99.5Min furnace gas crystallisation by cooling gradually, collect the Antimony Trioxide: 99.5Min crystal through the crystal transport pipe at last.
Also be provided with the choked flow baffle plate in the above mold; Said choked flow baffle plate is staggered on the mold interior wall; The effect of choked flow baffle plate is to prevent that the cold air that the crystal transport pipe flows into from directly pouring on the stibium trioxide stove through mold; Make the Antimony Trioxide: 99.5Min furnace gas shift to an earlier date crystallization, surging force and impact velocity that the choked flow baffle plate is staggered and can relaxes cold air.
Also vertically be provided with equidistant sensor for measuring temperature on the above mold interior wall, can recognize the temperature variation of Antimony Trioxide: 99.5Min furnace gas when the crystallization through sensor for measuring temperature, thus the size of the cold blast rate that control blasts.
But the above folding round mouth is arranged between the sensor for measuring temperature and/or on the horn-like interface A, but is setting up the folding round mouth can better make things convenient for the cold wind amount of blasting of regulating different steps between the transmitter and/or on the horn-like interface A.
Two ends of the above mold are connected with the crystal transport pipe with reactor drum with horn-like interface B through horn-like interface A respectively; Trumpet-shaped interface can provide a buffer zone so that the importing of Antimony Trioxide: 99.5Min furnace gas and Antimony Trioxide: 99.5Min crystal are derived, and makes can access better difference between the different devices.
The utlity model has following beneficial effect:
1. the Antimony Trioxide: 99.5Min purity that adopts the utility model to collect is high, and particle is thin, and is active high; Can obtain Fei Shi median size 0.80 ~ 1.8 μ m, whiteness L value>=98.0; Chemical Composition is Sb2O3>=99.6%, Pb≤0.06%, the senior Antimony Trioxide: 99.5Min product of As≤0.03%.
2. the utility model is simple in structure, only needs existing mold is added sensor for measuring temperature, gets final product but at the mold different positions some folding round mouths are set simultaneously.
3. the utility model is air to the wind that blasts, and does not need outer oxygen, thereby has practiced thrift manufacturing cost.
