Process and device for atomising liquid and/or pasty and/or pulverulent media, in particular liquids with particles, for example abrasive particles

摘要

Atomisation of media, for example liquid suspensions, have hitherto been achieved, for example, by means of, for example, plate-shaped baffle bodies disposed opposite feed nozzles for the medium. If the suspension contains abrasive particles, even baffle bodies made of extremely hard materials are subject to high wear. By means of the new process and the new device, atomisation with extremely fine degrees of atomisation is to be made possible without wear phenomena and/or damage to components, for example baffle bodies. At least two streams consisting of one or more media are merged with one another such that a baffle region for atomisation is generated in their impact region and an automatic atomisation effect occurs. The atomisation device (1) has at least two feedlines (5, 6) for the media flows to be merged with one another, which lines are arranged such that the flows impact on one another in a predetermined impact region (10).
