Description
TECHNICAL FIELD
[0001] The utility model belongs to the yellow phosphorus preparation technical field, concretely relates to a backflushing device of slag flushing pool. BACKGROUND
[0002] Yellow phosphorus is an important basic industrial raw material, and is widely used in chemical industry, pesticide, military and other fields. Yellow phosphorus is also called white phosphorus, which is a polymorph of phosphorus, white or light yellow crystal, soft, brittle when cold, color darkens when exposed to light, produces green phosphorescence and white smoke in dark place, ignites at about 40 DEG C in wet air, and ignites slightly higher in dry air. In the field of chemical industry, yellow phosphorus has wide application, including oil exploitation, printing and dyeing, papermaking, leather making, alloy manufacturing and other fields. In these industries, yellow phosphorus can be used as catalyst, reducing agent or raw material. In the field of agriculture, yellow phosphorus is an important raw material for pesticide production, such as herbicide and insecticide. In addition, yellow phosphorus can react with acid to generate phosphoric acid, which is the main raw material for manufacturing phosphate fertilizer, and plays an important role in improving crop growth and yield. In the military and special fields, yellow phosphorus can be used to manufacture smoke bomb, signal bomb and the like. In short, yellow phosphorus has very wide and important application.
[0003] At present, yellow phosphorus is produced by electric furnace smelting method. In the process of producing yellow phosphorus by this method, yellow phosphorus slag is generated, which is mainly composed of silicon, calcium, iron and other elements, and has high potential utilization value. The existing yellow phosphorus slag is in molten state after coming out of the electric furnace, and its temperature reaches 1300-1400 DEG C. It needs to be fully contacted with cold water to form granulated slag and realize water quenching. Then the yellow phosphorus slag flows into the quenching slag pool with water flow, and the water and yellow phosphorus slag are pumped into the slag bin for filtration and separation. The slag is discharged through the valve, and the water is led to the slag flushing pool through the pipeline.
[0004] At present, when the yellow phosphorus slag and water are separated in the slag bin, small particles of yellow phosphorus slag are easy to leak out of the filter screen and flow into the slag flushing pool with water. Over a long period of time, yellow phosphorus slag will accumulate at the bottom of the slag flushing pool, which seriously affects the use space of the slag flushing pool and also makes the subsequent cleaning very troublesome.
