Description

(54) СПОСОБ УТИЛИЗАЦИИ ОТХОДОВ ФОСФОРНОГО ПРОИЗВОДСТВА Изобретение относитс  к способам ути ( пизации твердых, жидких и газообразных отходов фосфорного производства, образую щихс  в процессе электротермического получени  фосфора из фосфорсодержащего сырь , в частности к способам переработ ки коттрельной пыли, фосшлама, осадков фосшламовой кислоты и неочищенных печных газов. Известен способ переработки фосшламов нагреванием с запыленными печными газами UlJ Однако способ не позвол ет вовлечь в переработку совместно коттрельную пыль, фосшлам. осадки фосшламовой кислоты , а также печные (очищенные и неочищенные ) газы. Наиболее близким по технической сущности и достигаемому эффекту к предлагаемому  вл етс  способ утилизации отходов фосфорного производства, включающий подачу в печь твердых отходов фосфорного производства (шламов), нагрев и плавление их при вводе топлива и отвод продуктов переработки. В качестве .тош1и ва используют природный газ l 2j . Недостатками способа  вл етс  плохоф качество получаемой фосфорной кисло.ты вследствие ее загр знени  сажистыми частицами и низщими соединени ми фосфора , что затрудн ет ее использование в качестве сырь  дл  производства фосфорных солей и удобрений. Кроме того, способ предусматривает переработку и утилизацию только одного вида отходов фос« форного производства. Другие виды отходов перерабатываютс  отдельно, что требует дополнительных затрат на сооружение ус тановок. Цель изобретени  - повыщение эффективности процесса путем совместной перй работки всех видов отходов фосфорного производства в одном аппарате с попуче нием качественных продуктов переработки (плавленных фосфатов и фосфорной кисло-f ты), пригодных дл  их дальнейшего использовани .(54) METHOD OF UTILIZATION OF Phosphate Production Waste The invention relates to methods of utilizing (powders, powders, powdered plastics, phosphorus waste, formed in the process of electrothermal phosphorus production from phosphorus-containing raw materials, in particular, to methods for processing ceramic dust, sweetener, phosphorus from phosphorus-containing raw materials, in particular to methods for the processing of ceramic dust, phosphorus from phosphorus-containing raw materials, in particular to methods for the processing of ceramic dust, phosphorus from a phosphorus-containing raw material, in particular to methods for processing ceramic dust, sweetener, phosphorus from phosphorus-containing raw materials, in particular to methods for the processing of ceramic dust, phosphorus from a phosphorus-containing raw material, in particular to methods for the processing of ceramic dust, phosphorus from phosphorus-containing raw materials, in particular, to the processing of ceramic dust, phosphorus from phosphorus-containing raw materials, in particular, to the methods of processing ceramic dust, foulshama, and phosphorus-containing materials. of uncleaned furnace gases. There is a known method of processing fosflams by heating with dusty furnace gases UlJ. However, the method does not allow to involve in the processing jointly sinter dust, sludge, precipitates of phoslamic acid, and furnace (purified and unpurified) gases. The closest to the technical essence and the achieved effect to the proposed is a method of recycling phosphorus production wastes, including feeding solid phosphoric production wastes (sludge) into the furnace, heating and melting them when introducing fuel and withdrawal of processed products. Natural gas is used as a trap l 2j. The disadvantages of the method are the poor quality of the phosphoric acid produced due to its contamination with soot particles Amy and lower phosphorus compounds, which makes it difficult to use as a raw material for the production of phosphate salts and fertilizers. In addition, the method involves the processing and disposal of only one type of waste from phosphate production. Other types of waste are treated separately, which requires additional costs for the construction of facilities. The purpose of the invention is to increase the efficiency of the process by jointly processing all types of phosphorus production wastes in one unit with the use of high-quality processed products (fused phosphates and phosphoric acid) suitable for their further use.
