PROCESS FOR CONVEYING GRANULAR SOLIDS

摘要

A PROCESS OF CONTINUOUSLY CONVEYING GRANULAR SOLIDS FROM A FIRST ZONE WITH A PRESSURE OF 0.4 TO 1.6 MPA (4 TO 16 BAR) THROUGH A DESCENDING LINE AND VIA AN ASCENDING LINE TO A SECOND ZONE WITH A PRESSURE WHICH IS LOWER THAN IN THE FIRST ZONE BY 0.3 TO 1.5 MPA (3 TO 15 BAR) , BY MEANS OF A GASEOUS MEDIUM.TO ENSURE THAT THE PRESSURE BETWEEN TWO REGIONS CAN BE REDUCED AT LOW COST AND WITH LITTLE MAINTENANCE EFFORT WHEN CONTINUOUSLY CONVEYING GRANULAR SOLIDS, A GASEOUS MEDIUM (9) IS INJECTED INTO A TUBE THROUGH AN UPWARDLY DIRECTED NOZZLE (6) AT THE POINT WHERE THE GRANULAR SOLIDS ARE CONVEYED THROUGH A DESCENDING LINE (2) INTO AN ASCENDING LINE (3).FIGURE 1
