FIELD: machine building.
SUBSTANCE: invention relates to mass exchange processes performance devices in heterogeneous fluid-solids systems and can be used in chemical, petrochemical, pharmaceutical, food, biotechnical and other industries. Pulsating device comprises a housing with a bottom and a lid with a neck, a container for solid particles placed in the neck, with the formation of the annular cavity between the side wall of the container and the housing of the device, the upper part of the side wall of the container is impermeable, and the lower part is permeable, the pressure oscillation driver connected to the upper part of the annular cavity, the flange connector in which the grate is mounted, pipe with a union and a check valve installed above the grate, a union with a check valve connected to the annular cavity, and process branch pipes. At that, the space of the container between the bottom and the grate is filled with a solid phase by 0.5–0.8 of the volume of space. Bottom of the container has the form of a revolution ellipsoid with an axis coinciding with the axis of the container, one of whose axle is equal to the radius of the container, and the second axle is in 1 to 3 times smaller than the first, or the shape of a flow divider, similar to a curved cone formed by rotating a quarter of an ellipse about the axis of the container, one of whose semi-axes is equal to the radius of the container, and the second axle is in 1–3 times smaller than the first.
EFFECT: invention provides an increase in the efficiency and degree of use of the solid phase, especially when processing particles having different buoyancy and / or polydisperse composition.
