Title: Methods of removing a deposit from a surface of a solid body
IPC: B08B5/02
Filed: 1973-12-03
Abstract: 1447250 Blasting SIEMENS AG 3 Dec 1973 [4 Dec 1972] 56003/73 Addition to 1364205 Heading B3D A method of removing a deposit from a surface of a solid body comprises projecting a stream of blasting particles which have a hardness less than 7 on Mohs' scale of hardness and less than the surface and which are entrained in a flow of pressurized gas to impringe on the deposit, and using a tornado flow dust collector to remove blasting particles and particles of deposit material from the blasting zone by suction. The surface may be a collecting chamber of a steam generator of a nuclear power station and the blasting particles may be boron trioxide. The tornado flow suction is produced by at least one vacuum pump or fan and removes the particles, the extraction capacity of the collector being such that as the main quantity of particles descends to the bottom of the blasting zone it is displaced towards the collector. The exhaust air is returned to a sealed chamber to form a closed circuit. In the collector, a stream of particle carrying gas passes through a tubular tower into which at least one gas jet is directed transversely of the incoming gas streams to produce a helically-rotating gas flow in opposition to the gas stream whereby particles are precipitated at a site near the entry of the incoming gas stream to the tower.
