In the application a spray dryer absorption apparatus for treating a stream of flue gas containing acidic components is disclosed. The apparatus comprises a chamber having vertical cylindrical walls, said chamber comprises (i) an inlet for a flue gas stream containing an acidic component, (ii) an atomizer for spraying droplets of an absorbent slurry into said flue gas stream to effect a chemical reaction between the droplets and the acidic component of the flue gas, thereby forming a particulate reaction product, and (iii) an outlet for the treated flue gas and entrained particulate reaction product, wherein the bottom of the chamber having vertical cylindrical walls is substantially horizontal and impervious to gases. The apparatus of the invention has the advantage of a simplified geometry accounting for lower building and maintenance costs.

The closure element (201) is adapted to be installed in a vessel wall provided with an aperture and has a peripheral flange (202, 222) and a central cover unit (203). The closure element (201) is provided with at least one light source (241) within a predefined zone (235) located in the central cover unit (203) and the light source is confined within the central cover unit.


The rotary atomizer is intended for a spray drying apparatus and comprises a feed supply pipe (104), a drive motor (102), a drive shaft (107), one or more bearings (111, 112, 113) supporting or guiding the drive shaft, and an atomizer wheel (106). At least one of the bearing or bearings (111, 112, 113) is a foil bearing. An additional supply device (114) for air or gas may be provided to be connected to the at least one foil bearing (111,112). Furthermore, the additional supply device (114) may be connected to further opening into a position nearby the atomizer wheel (106) by means of a branch connection (115).


In a spray drying apparatus, comprising in a usual manner a drying chamber, an air disperser, and at least one pressure nozzle arrangement (4), means are provided for emptying the feed in the nozzle arrangement(s) (4) after the supply of feed from a feed system (5) is halted and before the nozzle arrangement(s) (4) are removed from the drying chamber and positioned in a cleaning system (7). The emptying takes place while maintaining atomization in the nozzle arrangement (4). The feed emptying system (6) comprises a pump (60), a pressurized air/gas source (61) and a conduit (62), and the spray drying apparatus at least one valve (45, 53, 63, 64, 65, 66) allowing switching from the feed system (5) to the feed emptying system (6).

Disclosed herein is an external mixing pressurized two-fluid nozzle for atomising a liquid by means of liquid pressure and gas, comprising an inner feed liquid pipe (1) extending axially between an upstream end and a downstream end, having a feed liquid conduit (2), a feed liquid inlet (3) positioned at the upstream end and a feed orifice (4) positioned at the downstream end, and a co-axial first gas pipe (5) extending radially outside the inner feed liquid pipe (1) and forming a first gas conduit (6) between the first gas pipe (5) and the inner feed liquid pipe (1), the first gas pipe (5) having a gas outlet slit (7) positioned at the downstream end. Said external mixing two-fluid nozzle provides a swirling motion of the gas, which combined with a pressurized feed liquid enables the production of spray dried powder at industrially applicable capacities with low energy consumption and a small particle size.

A nozzle for cleaning-in-place of a vessel has a nozzle body to be connected to a wall of the vessel and defining an opening, a nozzle insert is contained within the nozzle body and is able to assume at least two distinct positions relative to the nozzle body, a first position in which the nozzle insert is retracted into the nozzle body and a second position in which the nozzle insert is advanced in the axial direction relative to the nozzle body and protrudes into the vessel. Apertures are exposed in the second position to allow distribution of a cleaning fluid. The nozzle insert has two nozzle insert parts, in mutual abutment in the first position and spaced from each other in a direction transverse to the axial direction in the second position to form a gap between adjacent nozzle insert parts, the apertures being exposed in the gap.

The insert (20) is adapted to be fitted into an atomizer wheel. Each insert (20) has a longitudinal axis and comprises an inner end face (21), an outer end face (22), an external surface (23) and an internal surface (24) defining a channel (35) having a centre axis (c) and extending between an inlet (25) at the inner end face (21) and an outlet (26) at the outer end face (22). At least the inlet (25) is offset from the longitudinal axis such that the centre axis of the channel (35) is offset from the longitudinal axis of the insert (20). The insert (20) is adapted to be utilized in an atomizer wheel for a spray dryer for atomizing slurries of abrasive material, for instance for spray drying absorption for flue gas cleaning.
