SU478167A1 - Kambinirovannaya installation for drying dispersed materials - Google Patents

Description

drying, for example, it can be made telescopic.

The installation has a gas-conducting device for creating a peripheral swirling flow of the secondary heating medium. It can be implemented in the form of a block, for example, nozzles 8 or louvers 9, which ensure the flow is curled.

The secondary coolant is supplied through the nozzle 10 to the block 11 or to the block 12 of the Nozzles 8 may have openings for adjusting the jet injection angle. The fitting 13 serves to exit the heat-treated and dust-free heat carrier, and the fitting 14; for dry, material through

cyclone 15; A screw 16 can be connected to the fitting 14 for removal of the mother - ala or another valve. To supply the source material, a feeder is connected to the fitting 3, for example, the screw 17, or the material is fed through fitting 3 into a venturi tube 8. The installation may have one or more fittings 19 for under; | primary heat carrier water, which: can also be used to supply the heat transfer medium with the material.

Into the flow of the primary coolant, by: stepping through the nozzle 2, is supplied through the nozzle 3 the initial wet material

The gas suspension enters the vortex pre-chamber 5, where the material is dried in a swirling flow. Fresh coolant j can be fed into the pre-chamber 5 through the nozzle 19. Next, the gas mixture re-interferes with the sub-commutator 4 and can

; be further twisted in the swirler 6. The divider 7 flow primary; The heat transfer medium with the material is displaced from the central zone and, rotating in the form of a hollow cylinder, is mixed to the outlet end of the dryer (housing 1).

Secondary fresh heat transfer fluid through connection 1O using nozzles 8 or 9 enters housing 1 and rotates along the periphery in the same direction as the flow of the primary coolant, but with a large radius of the spiral, moves towards the primary heat carrier, washing out the heat carrier material, dries it and mixes to the fitting 14 for unloading. All waste and dust-free coolant is removed through fitting 13.

Claims (2)

1. Combined installation for drying dispersed materials, for example chemical products, containing a vortex dryer with a pre-chamber with a tangential gas inlet, a final finishing box of larger diameter, equipped with a gas supply device for a hot-water carrier located on the opposite side gas suspension and discharge cycle, characterized in that, in order to intensify heat and mass transfer, the gas supply device is made in the form of tan entsialno mounted adjustable nozzle block for flow of secondary coolant twist in one direction with gas suspensions and the cyclone is directly connected to the largest cross section of the chamber. 2. The installation according to claim 1, wherein the dryer has an adjustable length, for example, is made telescopic. ig.2 g j
