Abstract
The invention discloses a yellow phosphorus ore processing technology, which comprises the steps of: continuously adding yellow phosphorus ore and fuel into a heating device according to calculated proportions, controlling the temperature of the heating device to be within a range of 900-1100 DEG C for 60-90min, and finally transporting the yellow phosphorus ore to a storehouse for future use after the heated yellow phosphorus ore is cooled to be less than or equal to 80 DEG C. The yellow phosphorus ore processing technology has the advantages that the carbonate and the crystal water in the yellow phosphorus ore can be effectively removed; compared with the relevant economic indicators of the existing yellow phosphorus production method, the power consumption per unit product can be decreased by 15-18%, the coke consumption is decreased by approximate 15% and the yield is improved by approximate 8%; and the content of arsenic in yellow phosphorus can be decreased by approximate 30%.
Description
Technical field
The present invention relates to a kind of complete processing of yellow phosphorus ore, belong to chemical technology field.
Background technology
Rock Phosphate (72Min BPL) in current phosphorus production, just just puts into production after simple processing treatment.Objectionable in Rock Phosphate (72Min BPL) affects phosphorus production cost and production efficiency as carbonate, crystal water, arsenic etc.Impurity is more, and loss on ignition is larger, and the output of yellow phosphorus is lower, and the power consumption in technological process is also larger, therefore, for the yellow phosphorus ore deposit ore that loss on ignition is larger, designs a kind of working method can removed impurity, reduce power consumption, has great meaning.
Summary of the invention
The object of the invention is to solve in phosphorus production the problem that is high, that yield poorly that consumes energy, provide a kind of complete processing of yellow phosphorus ore.
The object of the invention is to be achieved through the following technical solutions:
A complete processing for yellow phosphorus ore, comprises the steps:
(1) the yellow phosphorus ore raw ore of loss on ignition >=5%, diameter≤300mm is got, or loss on ignition >=5%, after processing, diameter is the yellow phosphorus ore concentrate of 15 ~ 80mm, the yellow phosphorus ore calculating Board Lot through chemical examination is heated to heat needed for 1100 DEG C and fuel used thermal content, in institute's heat requirement with can heat supplied ratio be 1: 1.05, draw yellow phosphorus ore and fuel-weight ratio, and in this ratio, yellow phosphorus ore and fuel are joined in heating unit continuously;
(2) temperature in heating unit is controlled in the scope of 900 DEG C ~ 1100 DEG C, keep 60 ~ 90min;
(3) by the yellow phosphorus ore after heating, after being cooled to temperature≤80 DEG C; It is for subsequent use that raw ore is transported to storage bin after fragmentation, screening, and it is for subsequent use that yellow phosphorus ore concentrate is directly transported to storage bin.
Described fuel can be gas, solid or liquid.
Described heating unit can be vertical, horizontal, floated, the formula of falling cigarette or trolley type; Described heating unit adopts vertical, horizontal, trolley type or floated when fuel is gas; The formula of falling cigarette is adopted when fuel is solid; Horizontal, floated or trolley type can be adopted when fuel is liquid.
The invention has the beneficial effects as follows: effectively can remove the carbonate in yellow phosphorus ore and crystal water; Compared with the every relevant economic target of original phosphorus production, unit product power consumption 15% ~ 18% can be reduced, reduce consumption burnt about 15%, improve output about 8%; Also can reduce the arsenic content about 30% in yellow phosphorus product.
