Yellow phosphorus mud ash recycling device with impurity removing function

Abstract

The invention discloses a yellow phosphorus mud ash recycling device with an impurity removing function. The yellow phosphorus mud ash recycling device with the impurity removing function comprises animpurity removing filter chamber and a heating furnace, wherein a slurry pump is arranged above the impurity removing filter chamber; a water inlet is formed in the right side of the slurry pump; a stirring motor is arranged on the right side of a vacuum pump; a stirring propeller is arranged below the stirring motor; a residue discharging port is formed in the left side of the impurity removingfilter chamber; a filtering plate is arranged on the right side of the impurity removing filter chamber; the heating furnace is positioned below the impurity removing filter chamber; a yellow phosphorus tail gas connecting pipe is arranged on the side surface of the heating furnace; a phosphorus steaming boiler is arranged above the heating furnace; a yellow phosphorus steam pipe is arranged abovethe phosphorus steaming boiler; a cooling spray tower is arranged on the right side of the yellow phosphorus steam pipe. The yellow phosphorus mud ash recycling device with the impurity removing function is provided with the filtering plate, and during using, the filtering plate can filter liquid yellow phosphorus and impurities so as to reduce the impurities, so that increase in the purity of aproduct is facilitated.

Description

technical field [0001] The invention relates to the related technical field of yellow phosphorus recovery, in particular to a recovery device for yellow phosphorus and phosphorus marl with the function of removing impurities. Background technique [0002] Phosphorus sludge is one of the main by-products produced in the industrial production of yellow phosphorus. Phosphorus sludge contains about 30% of yellow phosphorus. Yellow phosphorus is a toxic chemical. If it is directly discharged as industrial waste, it will not only cause waste of resources, Moreover, it pollutes the environment, and some existing physical recovery methods usually contain a large amount of impurities, and the recovery rate is low, while the chemical recovery method not only has high costs, but also easily causes secondary pollution. [0003] In view of the above problems, an innovative design is carried out on the basis of the original recovery device for yellow phosphorus and phosphorus marl. Cont...
