Embodiment Construction

[0020] FIG. 1 shows a sputtering layer arrangement, the arrangement cross section 9 of which is a rectangular cross section. FIG. 2 shows a perspective view of a part of the sprayed layer arrangement shown in FIG. 1 . The basic structure of the spray-level device comprises a supply air chamber 8 , an expansion zone 14 arranged thereon with an enlarged cross-section and a dedusting device 19 . In the housing 4 of the injection device, a delivery opening for the air supply 10 is arranged in the lower part of the air supply chamber 8, and an outlet opening for the exhaust gas 11 is arranged in the upper part of the injection layer device. The dedusting device 19 is provided with a filter cleaning device 18 known per se, which conducts the separated dust back into the reaction chamber 26 of the spray layer device.

[0021] Arranged in the axial direction in the housing 4 of the spray layer device in the region of the supply chamber 8 is at least one spray return wall 2 and one sp...

Abstract

The invention relates to a method for introducing liquids into a flow of solids of a spouted bed apparatus, and to a corresponding device. The invention is characterized by the formation of at least one near-circular flow of solids, which is situated in an axial direction of the reaction chamber of the spouted bed apparatus, during which the supply air necessary for forming the flow of solids, is supplied via a gap, which is located in the lower area an in the axial direction of the reaction chamber, and the liquid is introduced into the flow of solids at one or more locations by means of one or more single-component and / or multi-component nozzles. This enables the flow conditions in the nozzling area to be set whereby permitting the liquid to be introduced into the flow of solids in a specific and adjustable manner. The resulting final product is characterized by having a nearly homogeneous grain size with identical material properties. Different final products can be produced by spraying pure liquids, solutions, melts or the like into the flow of solids via one or more single-component and / or multi-component nozzles.

Description

technical field [0001] The invention relates to a method and a device for adding liquid to a solids flow of a spray bed arrangement. Background technique [0002] From DE 3117892 A1 a spray bed plant is known for the production of granulated products, in which a liquid is added to the solids flow of the spray bed granulator. The sprayed layer arrangement has a circular cross section, the lower part of which is conically tapered. In the conical part of the center of the spray layer granulator, a gas channel is opened, in which a nozzle is arranged for spraying liquid. A corresponding gas is supplied through the gas channel for maintaining the ejection layer. The centrally supplied gas entrains the liquid added via the nozzle along with a part of the material in the spray bed granulator, wherein the spray channels in which the material particles are formed are wetted by the liquid. Material ejected via the bottom surface of the cone is re-fed to the ejection channel, thereb...
