Description

one

The invention of: is carried out: to apparatus for processing fine materials in the fluidization mode and the combined action of gas and vibration, and can be used, for example, in the chemical industry.

In this area of technical fluidization, it is known to use apparatus ic rotating by a gas distribution grid, on which fine-dispersed material is placed, and processing gas is supplied below.

In addition, it is known that in a number of cases, the parameters of the fluidized bed can be improved by the combined action of gas and vibration, especially when processing materials aggregated for aggregation 2.

ON technical essence and constructively; The closest to the present invention is the well-known 3 apparatus, containing in the housing a rotating support grid for a solid material equipped with sector-shaped protrusions of triangular cross section, one side of which is inclined in the direction opposite to the direction of rotation. When the lattice rotates, the protrusions move under the material, raise it to loosen it. Such an implementation and such a lattice operation in a well-known apparatus is justified by the purposes of material discharge and does not correspond to the objectives of creating a vibratory boiling layer of material, the lower limit of the vibration frequency of which in world practice is 5 Hz. Therefore, the disadvantage of the known apparatus from the point of view of vibro-pulverization is that the protrusions are inclined to the walls of the apparatus body and when the lattice rotates and the material is pressed against them, it is difficult to fluidize and, consequently, to process the materials.

In order to improve the processing of materials in the fluidization mode by the combined action of gas and vibration in the proposed reactor, the sector-shaped protrusion is inclined to the axis of the apparatus casing.

FIG. 1 shows the proposed reactor in cross section; in fig. 2-reactor in the plan.

The grating rotation and gas supply are indicated by arrows.

The reactor consists of a housing 1, in the lower part of which a lattice 2 rotating with the gas distribution valve is installed, with a sector-shaped protrusion 3, the side of which 4 is inclined in the direction opposite to the direction of rotation, and the protrusion itself is inclined to the axis of the case. Gas is shed under the grate (ka-me, pa S, and the grate is filled with finely dispersed material b.

In this work, lattice 2 is rotated, and gas is fed under the lattice through the gas chamber 5. Sector-shaped protrusion 3 of the lattice, the raid of the aclonean side 4 on the particles of the bed, throws them up and dried, acts as a shaking action of the 1st layer. The optimum mode of operation, gas consumption, speed vrash; en. (the grids and vibration parameters are jointly selected for the material being processed according to known dependencies.

The effectiveness of the invention is expressed in improving the processing of materials that are especially prone to aggregation, due to the improved structure of the fluidized bed and an increase in the coefficients of heat and mass.

Isolation makes it possible to share the advantages of using a rotating gas distribution grid and means of vibration.
