摘要： A filter equipment containing a number of filter units of conventional design, connected directly to process equipment, in which dust laden vapors are evolved under vacuum. Means are used to back wash, dry and heat the individual filter bags during continuous operation. The backwashing, drying and heating is performed with superheated vapor having the same composition as the vapor evolved in the main process. After condensation, part of the vapor evolved in the main process may be diverted into an evaporator, superheated in the vapor phase and then used for the backwashing, drying and heating. If lines are too long resulting in vapor near the dew point, the effect of double expansion with partial condensation may be used to bring back the vapor to the superheated phase before backwashing a filter bag.

摘要： Apparatus and method for drying suspensions, solutions and free flowing materials in a drying chamber in a cylindrical housing wherein the material is fed directly into the inlet against a rotating impeller and a scraping means is used against a rotating drum surrounding the impeller which limits the size of the drying chamber, the dried material moving past a displacement element within the drum which curves out conically from the impeller toward the end of the cylindrical housing.

摘要： A process for continuously drying dusty, powdery and granular materials by means of the sensible heat of gas serving simultaneously as the heating medium and the carrier gas for the materials to be treated. A gas stream containing the material to be treated is introduced tangentially into a circular path of motion and the stream so introduced moves a number of revolutions in this path to create a revolving ring of particles. The revolving ring of particles if formed while the gas is continuously drawn off below the inlet level of the gas stream with the formation of a potential vortex sink. The untreated particles flowing in from the outside displace the already revolving particles until the revolving particles, after progressive treatment, are picked up by the suction of the exiting gas stream which carries them out of the circular path. The apparatus for carrying out this proces comprises a treating chamber in the form of a ring chamber with an inlet which opens up tangentially to an outer wall of the chamber and an outlet in the form of a container which is arranged axially and at least partially under the bottom of the ring chamber, the container having a tangential takeoff duct. The ring chamber is provided with a bottom which has a slightly rising radial slope toward the center of the ring chamber. The process and apparatus may also be used for cooling the materials and for reactions carried out by exchange between gaseous and solid-phase materials.
