METHOD AND DEVICE FOR DE-CLOGGING OF FILTER

摘要

FIELD: filtering. ^ SUBSTANCE: device comprises reactor for producing gas hydrofluoric acid that is discharged from the reactor through the filtering grid made of a cylinder and provided with filtering members secured to the top section of the reactor housing. The de-clogging of the filtering members is carried out by repeatable blowing them with an inert gas. The inert gas is blown along the axis of the cylindrical wall of the filtering member with a velocity of 300 m/s for a period of less than 1 s. ^ EFFECT: enhanced efficiency. ^ 13 cl, 9 dwg
