ABSTRACT:
A method and apparatus for removing solid material from a process system pressurized by a process gas, especially process gases having a high content of solid material. The method operates cyclically. In a first cycle, the solid material is separated, via filter cartridges of sintered material, and accompanied by pressure-relief, practically completely from pressure-relieved gas in a pressurized receiving tank. In a second cycle, the solid material is removed from the receiving tank. In a third cycle, while simultaneously cleaning the filter cartridges of solid material adhering thereto, the receiving tank is pressurized. Finally, in a fourth cycle, solid material is removed from the process system. The apparatus includes a receiving tank, with at least two filter cartridges being provided on the gas outlet side thereof. The filter cartridges, alone or together with a prior connected cyclone for separating-out large-grained particles of solid material, can be disposed in the receiving tank or a tank is separate therefrom.
