Abstract
The invention relates to a method of purifying pyrolysis gases preferably containing hydrogen halides and/or acidic gaseous sulfur compounds by simultaneous neutralization and dust separation in which the gas entraining large amounts of dusty solid particles is led through a bulk bed for the purpose of binding the gaseous pollutants, and an apparatus for carrying out said method. The problem of clogging and plugging of the bulk bed is solved in that the grains of the bulk bed are set in shocklike movement and are thus subjected to a minimum wear by mechanical abrasion, the clogging of the bulk bed filter thus being avoided and the purification of the gas improved.
