method for regeneration of dust from the outer surfaces of filter elements, and device for implementing the procedure

摘要

in the procedure for the regeneration of dust from the outside at least a hollow elongated element with a free space open end and a closed end, with the staubhaltiges gas is dedusted,the gas permeable filter element and from outside to inside of the gas flow and the dust to the outside of the element and the deposited dust is deposited on the inside of the element by a small gasimpuls one through the open en de element proposed treibgasstrahls abgereinigt,the one in the free space and treibstrahleinrichtung with the open end of the element oriented mouth carries, and based on treibgasstrahl free gas from the free space is sucked,is to improve the procedure for the regeneration is a sufficiently large uniformly distributed on the inside of the element druckgasimpuls providedthat the treibgasstrahl with the intake gas to enter the filter element dust by means of a in the open end of the element hineinragenden rohrartigen installed first on a predetermined route and then in a variety of led to the inside of the element a partial current is divided.
