Description of Embodiments
[0027] Broadly, the present invention provides a cross-flow plate micro filter 10 including a plurality of titanium membrane plates 18 formed via supersonic particle deposition.
[0028] Although the present invention will be described as a cross-flow plate microfilter, the skilled addressee will recognise that the present invention equally applies to a cross-flow tubular filter where the tubular element is comprises the titanium membrane plate 18 formed into a tubular structure.
[0029] Referring to Figure 1 , Feed stream 24 of a mixture of fluid and particulates is fed into the cross-flow plate micro filter 10 from pump 26. The feed stream is then directed tangentially across titanium membrane plates 18 on the fluted surface 20 through tangential flow 14. Retentate collects and flows on the fluted surface 20 to be collected distal to the feed stream 24 and pumped out as retentate outflow 22.
[0030] In one embodiment the tangential flow 14 causes scrubbing of plates to minimize the collection of retentate on the surface of the titanium membrane plates 18.
[0031 ] In one embodiment the retentate is fed back into the cross-flow plate micro filter 10 as part of the feed stream 24.
[0032] Filtrate 12 passes through the titanium membrane plates 18 and is removed from the system through filtrate stream 16.
[0033] The titanium membrane plates 18 are formed as follows.
[0034] A template is coated in a resin or comparable material and allowed to dry. After the resin has dried it is removed from the template. In a chamber, the dried resin is coated with fine particles of titanium powder by way of Supersonic Particle Deposition which bonds the titanium powder particles together to form the titanium membrane plate 18 by entraining particles in a supersonic gas velocity stream. The formed titanium membrane plate includes pores to allow fluid to flow through it.
[0035] Following Supersonic Particle Deposition, when the titanium powder has fused to form the titanium membrane plate 18, the plate is submerged in a chemical bath where the resin is dissolved leaving only the titanium membrane plate.
[0036] The titanium membrane plates 18 serve as filtration plates. This can be rectangular, square, circular or any other shape as understood by the skilled addressee.
[0037] The resin can be formed into any shape that the titanium membrane plate 18 is intended to take. In one embodiment shape of the template defines the shape of the
resin. In an alternative embodiment the resin is 3D printed to define the shape of the resin.
[0038] In one embodiment the resin includes glass or metal elements blended into it to increase the hardness of the resin when it has set. In one embodiment the metal or glass.
[0039] In one embodiment, the resin is a UV set or quick set resin.
[0040] As one side of the resin is flat from its formation on a template, one side of the titanium membrane plates 18 is smooth and the surface of the other side depends on the Supersonic Particle Deposition.
[0041 ] The chamber within which the resin is placed for Supersonic Particle Deposition is sealed and treated under pressure and temperature within to provide an open area of the titanium membrane plate 18 of 20 to 60%. In one embodiment the pressure within the chamber is between 7 bar and 30 bar. In one embodiment the temperature within the chamber is between 300 and 900^3.
[0042] The Supersonic Particle Deposition of titanium powder provides a thickness of between 0.1 mm and 3mm to the titanium membrane plates 18. In one embodiment a thickness of 0.5mm is achieved for the titanium membrane plates 18.
[0043] In one embodiment, the Supersonic Particle Deposition is robotically controlled to form the fluting of the fluted surface 20. The fluting is formed by depositing thicker layers of titanium powder.
[0044] In one embodiment, after the titanium membrane plate 18 is removed from the chemical bath it is coated to ensure that the desired pore range on the titanium membrane plate 18 is achieved.
