Definitions
- the present invention relates to the field of the physical separation of solid particles suspended in a liquid and / or liquids of different densities.
- It relates more particularly to a mechanical separation device that uses the effect of the centripetal force and therefore implements a means for creating and maintaining vortex to achieve the desired separation of solid particles from a liquid or a liquid more dense than another liquid with which it is mixed.
- Centrifugal centrifugation can separate two liquid phases, a solid phase suspended in a liquid phase, or even two liquid phases containing a solid phase.
- this technique consists in accelerating the liquid containing solid particles by a mechanically driven rotor, in order to project the heavier particles outwards and to concentrate the liquid freed from the particles or the least dense liquid in the central part of the centrifuge.
- the patent application US2016 / 0236208 discloses an example of a centrifugal separator dedicated to the separation of solid particles from a liquid phase in which they are mixed.
- the denser liquid is ejected outwards, that is to say toward the peripheral wall of the centrifuge while the less dense liquid is collected in the center.
- Such a separation by centrifugation is for example implemented for the extraction of water present in petroleum or else plasma present in human blood.
- patent US8182408B2 which relates to a centrifugal separator for the separation of liquids of different densities. While known centrifugal force mechanical separators are generally satisfactory in terms of separation efficiency, they have a number of disadvantages which can be enumerated as follows.
- Centrifugation requires rotating the rotor at high rotational speeds. Indeed, the separation efficiency depends directly on the speed of rotation. This leads firstly to a significant electrical energy consumption and also abrasion wear of the rotor materials and the fixed envelope around (stator), as well as a rise in temperature. This wear therefore requires the use of materials more resistant to abrasion and therefore expensive.
- the rotational speed defines quite precisely the size and / or the mass of the solid particles to be separated, which may be an advantage but which requires the implementation of several speeds of rotation when it is desired to extract particles of sizes. and / or different masses.
- the temperature rise induced by the rotation at high speed of the rotor can be detrimental for certain solid products that it is desired to separate. This can for example degrade organic products or heat-sensitive products.
- centrifugal separation Another disadvantage of the centrifugal separation is that the projection of the solid particles outwards on the stator wall can cause a harmful deposition up to clogging. Regular maintenance is required.
- the operation of the rotor may be impeded if the proportion of the liquid at the same time the more dense and the more viscous is too important compared to the lighter liquid. Indeed, the energy required to rotate the mixture is important and remains high if the rotor remains in contact with the most viscous liquid.
- the content of the oily phase obtained (bio-crude) in the aqueous effluents at the outlet of the reactor is of the order of 10 to 15%.
- the inventor believes that it can not reasonably be considered on an industrial scale a centrifugal separation for this application due in particular to the high energy consumption that would be required and the aforementioned drawbacks centrifugal separators.
- the object of the invention is to respond at least in part to this need.
- the invention relates, in one of its aspects, to a device for separating solid particles suspended in a liquid and / or liquids of different densities, comprising:
- a buffer tank of symmetry of revolution about a vertical axis, the reservoir comprising at least one injection orifice in liquid charged with solid particles or in at least two liquids of different densities, and an outlet orifice arranged in part lower around the axis of revolution of the tank;
- At least one means for creating and maintaining a vortex generating a centripetal movement of (the) liquid (s) from the periphery of the reservoir to its center on at least a portion of the height of the latter; the shape and / or the ratio between the dimensions of the reservoir and / or the means for creating and maintaining the vortex is (are) determined from the number of gold ⁇ ;
- a collection tube arranged below the outlet orifice of the reservoir, for collecting by gravity at least the solid particles, and / or the more dense liquid (s) concentrated towards inside the vortex.
- the solution according to the invention consists in using the centripetal motion to concentrate the solid particles or the densest liquid inwards.
- centripetal movement is meant here and in the context of the invention, the definition given by the author of reference [1], namely a convergent movement, contracting, consolidating, creative, favorable to integration , constructive and friction reduction.
- the radius of rotation gradually decreases, generating a acceleration that intensifies suction suction and decreases friction (centripetal acceleration).
- the device of the invention consists of a combination of the following means:
- a central collector along the axis of the reservoir to collect the concentrated solid particles at the bottom of the vortex.
- patent application CN 103537211 which relates to the activation and purification of water containing toxic chemical molecules.
- the patent application CN 103537220 discloses the generation of homogeneous emulsion.
- the respect of the golden ratio for the shape and / or the ratio of the dimensions of the reservoir will contribute to maintaining the centripetal movement optimally over the height of the reservoir.
- the density of the liquid makes the speed of rotation of the liquid will be close to zero at the inner wall of the buffer tank. A surface current is created which pushes the liquid towards this inner wall.
- This current will continue down the wall. Then, towards the bottom of the tank, that is to say near the outlet, the current returns to the center and goes down around the central axis of the tank. This current thus causes the solid particles or the densest liquid towards the center downwards, that is to say towards the outlet orifice and thus towards the inside of the collection tube.
