Principle of work: the present invention is by transforming the stibium trioxide stove, and adds a certain amount of oxygen in pressurized air, stablize pyritous simultaneously, keeps certain strong oxidizing atmosphere in the reaction chamber, with the quality of assurance product utilizing reaction heat to keep.
Because in the process of producing common weisspiessglanz, simultaneously can't guarantee enough strong oxidizing atmospheres keeping pyritous, therefore, in order to realize enough strong oxidizing atmospheres, we just add the part pure oxygen in the air that blasts, the content of oxygen improves about 0.5～1 percentage point in the feasible air that blasts, the speed of response of antimony in the control stibium trioxide stove, thus reach the purpose that keeps high temperature and enough strong oxidizing atmospheres.
The present invention is a kind of method of new production catalyst grade weisspiessglanz, its adopts, and liquid antimony surface blasts the compressed-air actuated method of oxygen enrichment in the stibium trioxide stove two side direction stoves, make and reach a high temperature in the stove between 1050～1150 ℃, and the strong oxidizing atmosphere in the maintenance stove, high temperature oxidation antimony flue gas is drawn from furnace roof, through obtaining product by the bagroom collection after the poly-deepfreeze.The stibium trioxide stove that present method adopts is transformed through simple, compare with common stibium trioxide stove, do not need to increase any new affiliated facility and can produce qualified product, the output of every bar oven can reach 10 tons/day, compares with the at present known production method that other produce the catalyst grade weisspiessglanz, has less investment, simple in structure, easy care, it is low to consume energy, output is big, advantages such as constant product quality.
The stibium trioxide stove is a kind of reflective stibium trioxide stove, and it mainly is made up of body of heater, reaction chamber and blast pipe.Because top temperature can reach 1200 degrees centigrade in the stove, and antimony liquid has erosion action to general refractory brick, so adopt antistripping refractory brick with antimony liquid contact part in the stove.Want in the production process, the air that antimony liquid in the burner hearth and blast pipe are gone into carries out fierce reaction and generates weisspiessglanz, and oxygen and responseless antimony steam more than needed are finished reaction process in reaction chamber, and reaction generation thing weisspiessglanz is drawn from top by reaction chamber at last and entered cooling system.In order to make the weisspiessglanz product can reach the catalyzer standard, the applicant has done following improvement:
A. blast pipe is directly blown to change into from the side from the top and tiltedly blow,, and be convenient to control response intensity with increase gas-to-liquid contact face;
B. change the reaction chamber internal diameter into 250MM from 350MM, reduce calorific loss, make under lower response intensity and still can keep stable response intensity;
C. will move 600MM backward from middle position in the reaction chamber, make, reduce the temperature fluctuation of reaction zone away from material charging region.
Output and product matter index:
Production method of the present invention has been tried out the time more than a year at our company's production plant, and mean yield reaches 10 tons/day, and accumulative total has been produced about 1000 tons of catalyst grade weisspiessglanz product.Raw materials for production are 0# antimony slabs, and the transmittance that obtains the weisspiessglanz product reaches more than 99%, can satisfy the requirement of production of polyester fully, and the specific product quality index is as follows:
