Embodiment 1

[0025] Using 300g metal antimony as raw material, raise the temperature of antimony white furnace 1 to 1000°C, put metal antimony into the front chamber 2 of antimony white furnace 1 to melt it, and blow air to the top blowing pipe a4 and side of the front chamber 2 The pipe a5 blows into a top blower and a side blower respectively to oxidize and volatilize the antimony to form antimony trioxide furnace gas; guide the antimony trioxide furnace gas into the breech 3, and blow it to the top blower pipe b6 and the side of the breech 3 The blowing pipe b7 blows into the secondary top blowing and the secondary side blowing respectively, so that the furnace gas continues to contact oxygen; after the temperature of the antimony white furnace 1 gas is further raised to 1200 ° C, the antimony trioxide furnace gas is introduced into the reactor 8, And keep the temperature of the reactor 8 stable; Finally, the high-temperature antimony oxide furnace gas is introduced into the annular jet ...

Embodiment 2

[0027] Using 50 kilograms of metal antimony as raw material, raise the temperature of the antimony white furnace 1 to 1000°C, put metal antimony into the front chamber 2 of the antimony white furnace 1 to melt it, and blow the top blowing pipe a4 and the side of the front chamber 2 Blowing pipe a5 blows into a top blowing and a side blowing respectively to oxidize and volatilize the antimony to form antimony trioxide furnace gas; guide the antimony trioxide furnace gas into the breech 3 and send it to the top blowing pipe b6 and the breech 3 The side blowing pipe b7 blows into the secondary top blowing and secondary side blowing respectively, so that the furnace gas continues to contact oxygen; after the temperature of the antimony white furnace 1 gas is further raised to 1300 ° C, the antimony trioxide furnace gas is introduced into the reactor 8 , and keep the temperature of the reactor 8 stable; finally, the high-temperature antimony oxide furnace gas is introduced into the ...

Embodiment 3

[0029] Using 20 kg of metal antimony as raw material, raise the temperature of antimony white furnace 1 to 1000°C, put metal antimony into the front chamber 2 of antimony white furnace 1 to melt it, and blow the top blowing pipe a4 and the side of the front chamber 2 Blowing pipe a5 blows into a top blowing and a side blowing respectively to oxidize and volatilize the antimony to form antimony trioxide furnace gas; guide the antimony trioxide furnace gas into the breech 3 and send it to the top blowing pipe b6 and the breech 3 The side blowing pipe b7 blows into the secondary top blowing and the secondary side blowing respectively, so that the furnace gas continues to contact oxygen; after the temperature of the antimony white furnace 1 gas is further raised to 1250 ° C, the antimony trioxide furnace gas is introduced into the reactor 8 , and keep the temperature of the reactor 8 stable; finally, the high-temperature antimony oxide furnace gas is introduced into the annular jet...

Abstract

The invention discloses a preparation device for catalyst-grade antimonous oxide, which comprises an antimony white furnace (1) and a reactor (8). The preparation device for the catalyst-grade antimonous oxide has the characteristics that the inner chamber of the antimony white furnace (1) is provided with a front chamber (2) and a rear chamber (3) which are communicated; the front chamber (2) and the rear chamber (3) are respectively provided with a blowpipe; one end of the blowpipe passes through the antimony white furnace wall to extend into the chamber; the other end of the blowpipe is arranged out of the antimony white furnace (1); the top of the rear chamber (3) is connected with the reactor (8); and the top of the reactor (8) is provided with a crystallizer. The preparation device for the catalyst-grade antimonous oxide has the advantages of simple structure and low manufacture cost. When the preparation device for the catalyst-grade antimonous oxide is used for preparing the antimonous oxide, only air needs to be compressed, and pure oxygen is omitted.

Description

technical field [0001] The invention relates to an equipment and method for producing antimony trioxide by a fire method, in particular to a catalyst-grade antimony trioxide preparation device. Background technique [0002] Catalyst-grade antimony trioxide is an important chemical raw material. When it is used as a catalyst in the polyester polycondensation reaction process, it is required that the catalyst not only have high purity, but also does not contain high-priced antimony tetroxide. At the same time, it is required to have High catalytic activity. At present, catalyst grade antimony trioxide is mainly prepared by fire method and wet method. [0003] In recent years, some published documents have reported methods for preparing antimony trioxide, such as: [0004] 1. Chinese patent, application number: CN200510031323.8, application date: 2005.03.11 Name: Catalyst-grade ultra-high-purity antimony trioxide production method and its device, abstract: A production of cat...
