Abstract
The present invention relates to a method for producing antimony white and its special-purpose equipment. Said method includes the following steps: firstly, heating and melting antimony; then stopping to heat, utilizing a spray gun positioned on the top of furnace body to spray oxygen-rich air or general compressed air upon the surface of antmony molten body, the oxygen volume concentration of oxygen-rich air is 21-80%, and spraying pressure is 0.1-0.4 MPa; finally condensing and collecting the gas-state antimony trioxide produced after oxidation of antimony by means of cooling flue duct and cloth bag chamber. It is characterized by adopting top-blowing oxidation with oxygen-rich air to raise oxidation speed of antimony and can raise production rate of equipment by 4-8 times.
Description
The present invention relates to a kind of production method and production equipment of antimony Chemicals.
Stibium trioxide is being commonly called as of antimonous oxide, is mainly used in plastics, rubber, coating and chemical fibre industry and makes retardant synergist.Existing stibium trioxide production method is at first antimony to be melted at the body of heater internal heating, then airduct is inserted and carry out air blast in the antimony solution, make the antimony oxidation generate the gaseous state antimonous oxide, the gaseous state antimonous oxide is introduced the cooling stack internal cooling, send into the cloth bag chamber at last and give condensation and collection.The advantage of this method is that technology is simple, pollution-free, and weak point is to use in the normal air blows, and causes equipment productivity low.In addition, because airduct directly inserts in the antimony melt, cause the airduct easy burn-out, loss is big, and brings the impurity effect quality product into.
The purpose of this invention is to provide a kind of novel method and isolated plant thereof of producing stibium trioxide, accomplish to improve equipment productivity and quality product.
The object of the present invention is achieved like this: improved generating gaseous state antimonous oxide production process before in the present stibium trioxide production method, promptly at first antimony is heated to melted state, stop heating then, spray into common pressurized air or oxygen-rich air by the spray gun that is positioned at the body of heater top is past apart from the antimony bath surface that is 30～300 millimeters, the oxysome volume concentrations of oxygen-rich air is 21～80%, ejection pressure is 0.1～0.4MPa, and temperature of reaction is controlled to be 700～1500 ℃.Subsequent handling repeats no more with production method is identical now herein.
Fig. 1 is for implementing the isolated plant structural representation of the production stibium trioxide that the method for the invention designs.
Isolated plant includes body of heater 3 and heating tube 7, and the cooling stack 2 on body of heater 3 tops links to each other with blower fan 4 imports Logical, blower fan 4 outlets are connected with 5 imports of cloth bag chamber, and the difference of it and common unit is oxygen enrichment unit 1 Outlet communicates with spray gun 6 on being positioned at body of heater 3 tops, and spray gun 6 exports apart from 30～300 millimeters on antimony solution surface. Spray Rifle 6 is seamless steel pipe or the high-temperature flame-proof pipe of 10～80 millimeters of diameters, and one or more can be installed.
Compared with the prior art, characteristics of the present invention are to adopt common compressed air or oxygen-enriched air top-blown oxidation, and are strong Changed the oxidation rate of antimony, made equipment productivity improve 4～8 times. In addition, because spray gun and antimony melt are not direct Therefore contact does not bring other impurity, good product quality into.
Embodiment one
In body of heater 3, add 3 tons of antimony regulus.At first connect the power supply of heating tube 7, make antimony regulus be heated to melted state, cut off heating tube 7 power supplys then, adjust oxygen enrichment unit 1, making oxygen concn is that 48% oxygen-rich air is sprayed onto on the antimony bath surface by the spray gun 6 that is positioned at the body of heater top.At this moment the rapid oxidation of antimony generates antimonous oxide steam, and the oxidizing reaction heat release is kept the interior temperature of body of heater more than antimon point, and between 700～1500 ℃, present embodiment is about 1300 ℃ by present all temps control techniques may command temperature of reaction.The gaseous state antimonous oxide enters cooling stack 2 coolings, is sent into cloth bag chamber 5 by blower fan 4 and carries out the condensation collection.Along with the carrying out of oxidizing reaction, if replenished 365 kilograms of antimony regulus every one hour in body of heater 3, diel can be produced 10 tons of stibium trioxides like this.The stibium trioxide quality index is as follows:
Composition: sb
2O
3〉=99.8% whiteness: 99 degree
Powder degree: 0.9～1.1 micron cubic content: 97%
Stain qualification rate: 100%
Embodiment two
This example and embodiment one are basic identical, and it is 21% common pressurized air that difference is to use oxygen concn, and the oxidation rate of antimony slows down to some extent, and output reduces, and other situation is constant.
Embodiment three
This example is basic identical with embodiment one, and difference is that the oxygen concn of oxygen-rich air is adjusted into 80%, and the oxidation rate of antimony is more rapid, and output is bigger.
Embodiment four
This example adopts laboratory installation shown in Figure 2.This device replaces oxygen enrichment unit 1 with the body of heater 3 of electric crucible furnace replacement isolated plant with oxygen cylinder, nitrogengas cylinder and threeway regulating mechanism.
Put into the crucible that 3000 gram star metals are housed in electric crucible furnace, heating up melts the antimony in the crucible, stops to heat up, and sprays into the oxygen-rich mixture of oxygen concn 35% and nitrogen concentration 65% to the antimony bath surface by the spray gun 6 that is positioned at furnace roof.The gaseous state antimonous oxide that the antimony oxidation generates gives the condensation collection through cooling stack 2 and cloth bag chamber 5.
Present embodiment can be collected stibium trioxide 3425 grams, and Chemical Composition meets 0
#The stibium trioxide standard, cubic content 98.5%, whiteness 99.8 degree.
Claims (3)
