Description

"Separator Apparatus"
Field of the Invention
The present invention relates to a separator apparatus. More particularly, the separator apparatus of the present invention is able to be provided "in-line" in a process stream. The separator apparatus of the present invention has further particular application in circumstances requiring removal of solids entrained in process streams that are not suited to use of other forms of filtering.
Background Art
The most commonly utilised separation apparatus for dust collection, or the separation of solids entrained in a gas stream, is the cyclone separator. In a typical separator, gas with entrained solids, such as dust, is directed tangentially into the top of a conical chamber. Entrained dust particles move toward the outside of the separator and are funnelled downwardly into a receiver. The clean gas is removed from the chamber through an upper central opening. Importantly, cyclones are used to remove both solids and liquids from gases.
In many circumstances it is necessary to retro-fit a separator into an existing fluid-flow line. Due to the physical constraints of the existing flow-line, with regard to space and orientation, it may not be possible to utilise a typical cyclone separator. In such circumstances filters of various forms may be utilised. However, in circumstances requiring minimum heat loss, filters are often inappropriate.
The separator apparatus of the present invention has as one object thereof to overcome substantially the above mentioned problems associated with the prior art.
The preceding discussion of the background art is intended to facilitate an understanding of the present invention only. It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was part of the common general knowledge in Australia or any other country or region as at the priority date of the application.
Throughout the specification, unless the context requires otherwise, the word "comprise" or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
Disclosure of the Invention
In accordance with the present invention there is provided a separator apparatus characterised by a fluid inlet, a fluid outlet, a separated solids outlet and a swirl vane, the swirl vane being located down stream of the fluid inlet but upstream of the fluid outlet and separated solids outlet, the swirl vane further being arranged so as to impart to the fluid flow passing therethrough a flow such that entrained particles move radially outward due to inertia, the fluid outlet being arranged inline with the fluid inlet and swirl vane whereas the solids outlet is fed by a radially arranged collector.
Preferably, the fluid outlet is of the same gauge as the fluid inlet.
Still preferably, the swirl vain is provided in a helical arrangement arranged axially along the flow path of the fluid inlet and fluid outlet.
Still further preferably, the collector is offset with respect to the axial orientation of the fluid inlet and fluid outlet so as to enhance flow of entrained particles to the solids outlet.
In one form of the present invention the swirl vane is provided in the form of four individual vanes arranged in a helical manner about a central axis of the fluid- flow path.
In accordance with the present invention there is further provided a method for the introduction of a separator apparatus into an existing fluid flow line, the method characterised by the removal of a portion of the existing fluid flow line and the introduction of an in-line separator apparatus as defined hereinabove.
Brief Description of the Drawings
The separator apparatus of the present invention will now be described, by way of example only, with reference to one embodiment thereof and the accompanying drawings, in which:-
Figure 1 is a cross-sectional side view of a separator apparatus in accordance with the present invention;
Figure 2 is a cross-sectional side view of a swirl vane provided in the separator apparatus of Figure 1 ; and
Figure 3 is a cross-sectional axial view of the swirl vane taken at B-B of Figure 2.
Best Mode(s) for Carrying Out the Invention
In Figure 1 there is shown a separator apparatus 10 in accordance with the present invention. The separator apparatus 10 is provided in a form suitable for introduction into a fluid low line in circumstances requiring the removal of entrained solids therefrom.
The separator apparatus 10 comprises a fluid inlet 12 and a fluid outlet 14. Substantially adjacent the fluid inlet 12 is provided a temperature indicator 16 and a pressure indicator 18. A further pressure indicator 20 is provided adjacent the fluid outlet 14.
The separator apparatus 10 further comprises a fluid flow modulating portion or swirl vane 22. The swirl vane 22 is provided within the bore of a piping 24 that forms it and the remainder of the separator apparatus 10 in large part. - A -
Down stream of the swirl vane portion 22 is provided a collector, the collector comprising a radially flared portion 26 of the separator apparatus and an off-set collecting surface 28, which in turn feeds solids to a solids outlet 30. The fluid outlet 14 projects upstream through the collector surface 28 and terminates at a point generally mid-way between the up-stream radial flared portion 26 and the surface 28.
In Figures 2 and 3 there is shown the swirl vane portion 22 comprising a pipe 32 defining a bore 34, an inlet end 36 and an outlet end 38. Within the bore 34 is located a swirl vane 40 comprising 4 intersecting vanes 42, the intersection thereof is provided co-axially within the bore 34 of the pipe 32. The vanes 42 are arranged so as to describe a helical structure within the pipe 32.
In use, fluid flowing into the separator apparatus 10 has induced therein a swirling or rotational movement whereby entrained solids move radially outward due to inertia as they pass downstream of the swirl vane portion 22. The solid particles generally move into the flared portion 26 and are collected against the collector wall 28 and fed to the solids outlet 30, whilst fluid containing substantially less entrained solids pass into the piping comprising the fluid outlet 14 and which is arranged co-axially with the swirl vane portion 22 and fluid inlet 12.
The separator apparatus 10 of the present invention is arranged such that it is substantially in-line or co-axial with regard to existing fluid flow, thereby allowing it to be inserted into an existing fluid flow line with minimal re-engineering required.
Further, the separator apparatus 10 of the present invention will result in minimal heat loss from a fluid flow, particularly when compared with typical filter means that might otherwise be utilised. Largely for this reason the applicant considers the separator apparatus 10 to have particular application in the Bayer process when installed in vapour lines between flash tanks used for flashing hot pregnant liquor and shell and tube heat exchangers which utilise the hot vapour from flashing to heat spent liquor. These heat exchangers are subject to clogging and scale build up, which may result in inefficient heat exchange and require costly and difficult maintenance. The provision of separator apparatus' 10 in these vapour lines is expected to significantly improve the performance of the heat exchangers over time.
Modifications and variations such as would be apparent to the skilled addressee are considered to fall within the scope of the present invention.
