Abstract (en)
[origin: WO2014131771A1] The invention relates to a particle blasting device (11, 11') and a method for generating a mixed jet composed of frozen particles, in particular CO2 particles, and a carrier gas and for pressure blasting by means of the mixed jet composed of frozen gas particles and the carrier gas. The particle blasting device (11, 11') has a flow duct (3), an expansion space (2), a rotatable agglomeration wheel (6), a connecting duct (12) between the expansion space (2) and the flow duct (3), and an outlet (8). The flow duct (3) has an inlet (10) for introducing a carrier gas. The expansion space (2) serves to generate agglomerated frozen gas particles from a liquefied gas and has an inlet (4) for introducing the liquefied gas. The rotatable agglomeration wheel (6) serves to agglomerate gas particles and is connected downstream of the expansion space (2) and arranged between the expansion space (2) and the flow duct (3). The expansion space (2) is connected to the flow duct (3) via the connecting duct (12). The outlet (8) is arranged at a distal end (13) of the flow duct (3) and configured to accelerate a mixed jet comprising the gas particles and the carrier gas.
