Abstract
The present invention relates to a reflection type plasma antimony white furnace with double reaction chambers, which is a device for producing catalyst grade antimonous oxide for polyester by a plasma method. Metallic antimony is oxidized and evaporated in a first reaction chamber, and enters a second reaction chamber to react with plasma flows; the gaseous antimonous oxide is suddenly cooled by air during passing through water jacket at an outlet so that the catalyst grade antimonous oxide is obtained. When the device of the present invention is used, the manufactured catalyst grade antimonous oxide has high purity, activity and solubility, and meets the production requirement of the polyester. The present invention has the advantages of simple production technology, low energy consumption and low cost.
Description
The present invention relates to a kind of is that raw material is used the plasma technique production polyester production equipment of urging agent level antimonous oxide with the metallic antimony.
As polyester (PET) synthetic catalyst is the important use of antimonous oxide, the catalyst grade antimonous oxide except that require purity height, foreign matter content low, the most important thing is to have high catalytic activity and solvability, though and common ANTIMONY TRIOXIDE SB 203 99.8 PCT is of high grade, do not possess as desired activity of polyester catalyst and solvability.
Preparation catalyst grade three oxygen two antimony all adopt wet method at present, and what generally use is chlorinolysis, is raw material with high-grade common ANTIMONY TRIOXIDE SB 203 99.8 PCT mainly, through peroxidation, and hydrolysis, processes such as washing and filtering, oven dry.And adopt non-wet processing production, as traditional metallic antimony oxidation style, plasma method there is no report.
For comparative descriptions novelty of the present invention, the metallic antimony oxidation style of producing common ANTIMONY TRIOXIDE SB 203 99.8 PCT and the relevant devices of plasma method are done a summary here.Traditional metallic antimony oxidation style mainly adopts the stibium trioxide stove of reverberatory furnace structure, generally the type of furnace of Shi Yonging is exactly a kind of stibium trioxide stove with reaction chamber that Chinese patent application is announced for No. 85102489, its constitutional features is laterally to be hung with two identical reaction chambers by the reflection furnace roof in stove, the lower part outlet of each reaction chamber is facing to high temperature antimony melt, and top exports and air cooling flue UNICOM.Metallic antimony is oxidized to the antimonous oxide steam in a reaction chamber, acutely cooling in the air cooling flue again, 950～1000 ℃ of reaction chamber temperatures, what Chinese patent application was announced for No. 88103221.2 is that a kind of plasma method is produced antimonous oxide ultrafine powder technology.This invention is a raw material with stibium trioxide or antimony sulfide fine ore, adopting the direct-current plasma producer is thermal source, in a reactor, make powdered raw material and plasma jet effect, through a condensation or gasification oxidation one condensation process of gasifying, obtain common antimonous oxide ultrafine powder, U.S. Pat 437060 was also announced similar techniques.
The purpose of this invention is to provide a kind of is that raw material is used the production equipment of plasma technique production polyester with the catalyst grade antimonous oxide with the metallic antimony.
The present invention is a kind of plasma antimony oxide furnace with reflection type dual-reaction chamber, and its main feature is the dual-reaction chamber structure.The metallic antimony major part that high temperature evaporates down is oxidized at first reaction chamber, generates gasiform antimonous oxide and the not oxidized antimony steam of part, enters second reaction chamber through passage, and with the effect of high-temperature plasma stream, the antimony oxidation is complete, and gas temperature raises rapidly.The gaseous state antimonous oxide by poly-cold, promptly obtains qualified product in the exit then.
Fig. 1 is the sectional view of device of the present invention, and described plasma antimony oxide furnace with reflection type dual-reaction chamber is by nozzle (1), burner hearth (2), first reaction chamber (3), an airduct (9), secondary air channel (4), inferior oxygen discharge outlet (5), passage (6), high frequency plasma producer (7), second reaction chamber (8), clean-up port (10), watercooling jacket formations such as (11).
Contrast Fig. 1 further specifies the present invention, at jet hole (1) install combustion device, and the metallic antimony in the heat fused burner hearth (2), and furnace temperature risen to 1000 ℃, at this moment, flue gas can drain into time oxygen dust-precipitator through inferior oxygen discharge outlet.Stop heating, start plasma generator (7), change normal running over to.By blasting oxygen-rich air in the antimony liquid of an airduct (9) below first reaction chamber and blasting oxygen-rich air on the first reaction chamber top by secondary air channel (4), make the antimony vapor-phase oxidation become the gaseous state antimonous oxide, pass through passage (6) again and enter second reaction chamber (8), with the temperature plasma flow effect more than the K that sprays by high frequency plasma producer (7) from the top up to 4000 °, the antimony oxidation is complete, gas temperature raises rapidly, through water jacket (11) and add air quenchedly, can obtain polyester in reaction chamber outlet with urging agent level antimonous oxide to 200～300 ℃.
Second reaction chamber of the present invention (8) adopts L type structure, and plasma jet adds from the top, guarantees desired temperature, also is convenient to operation, and one time airduct system adopts steel pipe or high-temperature ceramic.
Device of the present invention has the following advantages: (1) first reaction chamber temperature can be controlled at more than 1100 ℃ and not influence quality product, and adapting to the metallic antimony is raw material; (2) utilize the high frequency plasma body heat source, avoid generating the high price weisspiessglanz, guarantee the catalytic activity and the solvability of product; (3) do not produce waste water,waste gas and industrial residue, technical process is short, good product quality.
Utilize generation device of the present invention, the product of gained has advantages of high catalytic activity and solvability, purity height, fine size, single cube of crystallization, and good light stability reaches the requirement of polyester with the catalyst grade antimonous oxide fully.
For example, be raw material with the metallic antimony, its Chemical Composition is (weight %) Sb 99.79, Pb 0.134 As 0.03 Fe 0.04, adopts device of the present invention, the quality of producing the catalyst grade antimonous oxide that obtains is as follows:
The single isometric system of crystal formation
Ethylene glycol dissolving transmitance (%) 97
Dissolving with hydrochloric acid transmitance (%) 98
Mean particle size (micron) 0.4
Chemical Composition (% weight)
