Abstract

A cyclone separator for use in separating a solid particulate from the gas or liquid medium. The separator is provided with a housing (H), an outlet (4) for discharging the solid particulate separated from the medium, a pipe (13) for evacuating the clean fluid from the housing (H) and a swirling means capable to impart verticals motion to the medium. The swirling means is formed with a plurality of slit-like openings (16) arranged on the periphery thereof. The openings (16) are dimensioned so as to provide for the total open area sufficient for imparting to the medium intensive vortical motion.

Claims

AMENDED CLAIMS[received by the International Bureau on 23 November 1998 (23.11.98); original claim 1 amended; remaining claims unchanged (3 pages)]

1. A cy41one separator generally for separation of paniculate matter from solid taden fluid by virtue of vortical motion thereof, said separator comprising - a housing defined by a cylindrical peripheral wall thereof and by upper and lower extremities, said housing having a longitudinal axis and being provided with at least one inlet opening for entering said solid laden fluid thereinto, said inlet opening being formed within said peripheral wall and being directed preferably tangentially with respect thereto, - an outlet means for discharging separated solid paniculate from said housing, said øutlet means being formed preferably as a hollow truncated cone, the large base thereof being in communication with the lower extremity of said housing and the small base thereof being in communication with appropriate collecting receptacle, - a pipe means for evacuating the clean fluid from said housing, said pipe means being placed within said housing preferably coaxially with the longitudinal axis, an uppermost extremity of the pipe means being located outside of the housing and a lowermost extremity of the pipe means being located within the housing,

- at least one swirling means for imparting vonical motion to said fluid, said swirling means being formed as a tubular member, mounted within said housing coaxially with longitudinal axis of said housing so as to provide for annular space therebetween, said tubular member being provided with a plurality of slit-like openings, formed in the periphery thereof so as to enable communication between said annular space and the interior of said tubular member, characterized in that said pipe means extends along the swirling means and said openings are arranged regularly on periphery of said member so as to extend substantially tangentially with respect to the interior thereof, wherein said openings are defined by a length and width dimension being chosen so as to provide for the total open area which is sufficient for imparting to the fluid entering the interior of said swirling means of intensive vortical motion, said vortical motion being defined by a linear velocity 60-100 m sec, being preferably 60-70 m/sec.

2. A cyclone separator as defined in claim 1, characterized in that the length dimension of said openings is parallel to said longitudinal axis.

3. A cyclone separator as defined in claim 1, characterized in that said tubular member is assembled from at least two modular units, each of said units being defined by a cylindrical peripheral wall thereof and by opposing upper and lower annular extremities thereof, wherein said slit-like openings are formed in peripheral wall of said modular units and their upper and lower extremities are provided with a mating means enabling the assembling of said modular units together.

4. A cyclone separator as defined in claim 3, characterized in that said mating means are formed as a protrusion and depression arranged respectively on said upper and lower opposite extremities of said modular units, wherein annular protrusion of one modular unit is insertable within the corresponding annular depression of the adjacent modular unit.

5. A cyclone separator as defined in claim 3, characterized in that the openings of each modular unit are formed in two opposite regions of said periphery wall and are separated therebetween by an intermediate region, one of said opposite regions being adjacent to the upper extremity of said modular unit and the other opposite region being adjacent to the opposite lower extremity thereof

6. A cyclone separator as defined in claim 2, characterized in that said swirling means is formed with plurality of vanes, said vanes being arranged regularly along a circular path, preferably tangeiuialiy with respect thereto and said openings are formed by open spaces between the adjacent vanes.

7. A cyclone separator as defined in claim 1 , characterized in that said housing is provided with a baffle means for evacuating of fine and medium paniculate separated from said fluid, said baffle means being formed as a cylindrical chamber having a diameter exceeding the diameter of said swirling means, said baffle means being mountable on the upper extremity of said housing so as to be in communication with the interior of said swirling means.

8. A cyclone separator as defined in claim 1, characterized in that said pipe means is provided with a baffle chamber for evacuating fine paniculate separated from said fluid, said baffle chamber having a diameter exceeding the diameter of said pipe means.

9. A cyclone separator as defined in claim 8, characterized in that said pipe means is provided with a retardation means for retardation of the vortical motion of said fluid, said retardation means preferably being mounted above said baffle chamber and provided with guiding vanes directed oppositely to the direction of the vortical motion of said fluid.

10. A cyclone separator as defined in claim 1, characterized in that it is provided with a liquid distributing means for wet cleaning of said fluid, said liquid distributing means being formed as a cylindrical chamber mountable on the upper extremity of said housing and being in communication with the interior of said housing, said cylidndrical chamber being provided with liquid supplying inlets for supplying said liquid thereinto.

STATEMENT UNDER ARTICLE 19

Claim 1 (the main claim) of the above application has been amended to include the features referring to the "pipe means", e.g. the disposition thereof with respect to the housing and extending thereof along the "twirling means".

The features referring to the introduced amendments can be found in the specification on p.9, line 13, p.11 , lines 29-3 l,p.14, line 3.

The introduced amendments do not go beyond the disclosure in the above referred-to application as filed, they do not introduce any new matter and there is no impact on the description and the drawings.

None of the above features referring to the pipe means can be found in the references cited in the Search Report issued in the above application and therefore the Applicant respectfully requests reconsideration of the characterization of the references during Chapter II examination.
