Abstract
The invention relates to a method for recycling yellow phosphorus from phosphorus mud by using centrifugal separation method. The invention includes the following steps: the phosphorus mud is thrown into a phosphorus mud pot to be water sealed and evenly stirred; temperature is controlled at 70-80 DEG C and heat is preserved for 1-2 hours; then the yellow phosphorus is thrown into a centrifuge with filter cloth through a pipeline; separation factor of the centrifuge is controlled at 900-1,000; the yellow phosphorus is separated by the method of centrifuging in a melting state; the yellow phosphorus product is obtained after cooling and solidifying. By adopting the method of the invention, recycling rate of the yellow phosphorus from the phosphorus is above 99 percent; contents of the recycled yellow phosphorus is above 99.99 percent with high purity, meeting the industry-grade demand of national standard. The invention also has the advantages of simple equipment, little investment, immediate effect, simple technique, being conducive to industrialization, no pollution, recycling use of the waste water and capability of the residue for producing phosphate fertilizer.
Description
Technical field
The present invention relates to a kind of method that from phosphorus mud, reclaims yellow phosphorus, particularly a kind of method that from phosphorus mud, reclaims yellow phosphorus with centrifugal separation.
Background technology
Phosphorus mud is the by product that certainly leads in the electric furnace process phosphorus production, and the yellow phosphorus that is contained in the phosphorus mud must reclaim, with the productive rate that improves yellow phosphorus, prevent its pollution to environment.The method of handling phosphorus mud at present is a lot, useful chemical method and physics method reclaim yellow phosphorus from phosphorus mud, clay phosphoric acid of phosphorus and phosphoric acid salt etc., each tool pros and cons of these methods, chemical method and physics method are handled phosphorus mud finite capacity, and be dangerous and big to equipment corrosion, the rate of recovery is low, and the energy consumption height is uneconomical, the product acrobatics content height that clay phosphoric acid of phosphorus and phosphatizing phosphorus mud are produced does not have a satisfied treatment process as yet.For a long time, reclaim yellow phosphorus from phosphorus mud is a difficult problem in the phosphorus production always.
Summary of the invention
Purpose of the present invention is exactly will provide a kind of to reclaim the method for yellow phosphorus with centrifugal separation from phosphorus mud, and it has overcome above-mentioned the deficiencies in the prior art, and technology is simple, yellow phosphorus rate of recovery height.
The object of the present invention is achieved like this: a kind of method that reclaims yellow phosphorus with centrifugal separation from phosphorus mud, phosphorus mud squeezed into water seal stirs in the phosphorus mud pot, temperature is controlled at 70 ℃-80 ℃, be incubated 1 hour-2 hours, by pipeline it is squeezed in the whizzer of band filter cloth then, the separation factor of control whizzer is 900-1000, and yellow phosphorus is separated it by centrifugation method under molten state, obtains the yellow phosphorus product after the cooled and solidified.
Adopt method of the present invention, the yellow phosphorus rate of recovery is more than 99% in the phosphorus mud, and the yellow phosphorus content of recovery is more than 99.99%, and the product purity height meets the requirement of GB technical grade.The present invention has also that equipment is simple, investment is little, instant effect, technology are simple, be beneficial to industrialization, pollution-free, waste water can be recycled, and recrement is used to produce characteristics such as phosphate fertilizer.
Embodiment
A kind of method that from phosphorus mud, reclaims yellow phosphorus with centrifugal separation, phosphorus mud squeezed into water seal stirs in the phosphorus mud pot, temperature is controlled at 70 ℃-80 ℃, be incubated 1 hour-2 hours, by pipeline it is squeezed in the whizzer of band filter cloth then, the separation factor of control whizzer is 900-1000, and yellow phosphorus is separated it by centrifugation method under molten state, obtains the yellow phosphorus product after the cooled and solidified.Yellow phosphorus content is more than 99.99%, and the yellow phosphorus rate of recovery is more than 99% in the phosphorus mud, and filter residue is collected and produced fertilizer, so finishes a technological process.
Claims (1)
1. method that from phosphorus mud, reclaims yellow phosphorus with centrifugal separation, it is characterized in that: phosphorus mud is squeezed into water seal stirs in the phosphorus mud pot, temperature is controlled at 70 ℃-80 ℃, be incubated 1 hour-2 hours, by pipeline it is squeezed in the whizzer of band filter cloth then, the separation factor of control whizzer is 900-1000, and yellow phosphorus is separated it by centrifugation method under molten state, obtains the yellow phosphorus product after the cooled and solidified.
