Abstract

A particle separator includes a particle separation member to separate particles from liquid; a particle collection member for collecting particles from the particle separation member; and a liquid guiding member for guiding liquid flowing from the particle separation member to an outlet. The particle separation member includes an inlet for receiving un-clean liquid, a first separation section configured for preliminarily separating particles from the liquid, and a second separation section for separating further particles from liquid flowing from the first separation section. The second separation section includes a plurality of cyclones each having a wide open end connected to the first separation section and a narrow open end connected to the particle collection member.

First claim

The invention claimed is:

1. A particle separator comprising:
a particle separation member configured for separating particles from a liquid;
a particle collection member in communication with the particle separation member configured for collecting particles from the particle separation member; and
a liquid guiding member in communication with the particle separation member for guiding liquid from the particle separation member to an outlet;
wherein the particle separation member comprises an inlet for receiving liquid, a first separation section configured to preliminarily separate particles from the liquid flowing from the inlet, and a second separation section configured to separate further particles from the liquid flowing from the first separation section, the first separation section comprising a precipitator connected directly to the inlet, the second separation section comprising a plurality of cyclones each having a wide open end in communication with the first separation section and a narrow open end in communication with the particle collection member, and the precipitator is connected to the particle collection member,
wherein the first separation section further comprises a conical cavity located between the precipitator and the second separation section, the conical cavity having a wide open end connected to the precipitator and a narrow open end remote from the precipitator, the wide open end being closer to the inlet than the narrow open end,
wherein when the liquid flows through the precipitator and the conical cavity the liquid flows in a helical path and relatively heavier/bigger particles fall to a bottom of the precipitator and then into the particle collection member to thereby preliminarily separate particles from the liquid.

2. The particle separator of claim 1 , further comprising a flow distribution member connected between the first separation section and the second separation section, wherein the flow distribution section comprises a first cylindrical cavity connected to the narrow open end of the conical cavity, a plurality of second cylindrical cavities each connected to the wide open end of a corresponding cyclone, and a plurality of connecting channels each connecting a corresponding second cylindrical cavity with the first cylindrical cavity.

3. The particle separator of claim 2 , wherein a vortex finder is disposed coaxially in each second cylindrical cavity and communicates the respective second cylindrical cavity with the liquid guiding member.

4. The particle separator of claim 3 , wherein the vortex finder comprises a skirt section, the outer diameter of which increases in a direction away from the liquid guiding member.

5. The particle separator of claim 2 , wherein the connecting channels are arranged such that liquid is directed tangentially to the second cylindrical cavity.

6. The particle separator of claim 1 , wherein the inlet directs liquid tangentially to the precipitator.

7. The particle separator of claim 3 , wherein the liquid guiding member includes a chamber in communication with the second cylindrical cavities via the vortex finders, an outlet, and a guiding hub with a curved guiding surface disposed in the center of the chamber, the guiding surface facing the outlet and configured to guide liquid from the particle separation member toward the outlet.

8. The particle separator of claim 1 , wherein the particle collection member defines a through opening connected to the precipitator, and a drain opening, the axis of the drain opening being parallel to the axis of the precipitator, two valves being respectively disposed at the through opening and the drain opening.

9. The particle separator of claim 8 , wherein the two valves are integrally formed as a single unit.

10. The particle separator of claim 1 , wherein the particle separation member is integrally formed as a single piece monolithic structure with a plurality of voids formed therein, the voids forming the conical cavity and the cyclones respectively.

11. The particle separator of claim 1 , wherein the particle separation member, liquid guiding member, and particle collection member are made from transparent or translucent materials.

12. The particle separator of claim 1 , wherein the particle separation member, liquid guiding member, and particle collection member are made from a thermally stable plastic material.

13. The particle separator of claim 12 , wherein surfaces of the thermally stable plastic are modified with polymers selected from group of fluorodecyl polyhedral oligomeric silsesquioxanes.

14. The particle separator of claim 12 , wherein the thermally stable plastic material are reinforced with mica particles, glass fibers or carbon micro- and nano-fibers.

15. The particle separator of claim 1 , wherein the outlet is located at a top end of the separator and a drain is located at a bottom end of the separator and connected to the particle collection member.

16. A particle separator comprising:
a particle separation member configured for separating particles from a liquid;
a particle collection member in communication with the particle separation member, configured for collecting particles from the particle separation member; and
a liquid guiding member in communication with the particle separation member for guiding liquid from the particle separation member to an outlet;
wherein the particle separation member comprises an inlet for receiving liquid, a first separation section configured to preliminarily separate particles from the liquid flowing from the inlet, and a second separation section configured to separate further particles from the liquid flowing from the first separation section, the first separation section comprising a precipitator connected directly to the inlet such that when the liquid coming from the inlet flows into the precipitator it forms a whirlpool or vortex, the precipitator being connected to the particle collection member via a valve such that particles are capable of falling to the particle collection member when the valve is open,
wherein the second separation section comprises a plurality of cyclones each having a wide open end in communication with the liquid guiding member via a vortex finder and a narrow open end in communication with the particle collection member, the inlet being located outside of the particle collection member without passing through the particle collection member.

17. The particle separator of claim 16 , wherein the particle separation member is integrally formed as a single monolithic structure with a plurality of voids formed therein, the voids forming the cyclones.

18. The particle separator of claim 16 , wherein a vortex hub is formed at the valve.
