Description

An apparatus for removing suspended particles from liquids by means of a constant electric current is known. However, during the electrolysis process in these devices, the chemical composition and some physical and technological parameters of the liquid may change, and this will impair its quality.

The proposed apparatus for clarifying a liquid with a constant electric current differs from the known ones in that the anode rods are inserted into tubes of electrically insulating material embedded in the internal septum of the vessel and the cathode is separated from the main mass of the clarified fluid with a wire mesh, so that the electrolysis process takes place without contact of the anode rods with the clarified liquid, and in this way its qualities are not impaired.

The scheme of the proposed apparatus is shown in the drawing.

The apparatus consists of three sections I, 2 and 3. In the first two sections the liquid is saturated with gas bubbles formed during electrolysis on the cathode surface. The bulk of the suspended particles rises to the surface as a result of flotation. The remaining suspended particles that adsorb gas bubbles, but did not manage to rise in the first two sections, rise to section 3. In each of the three sections, there are partitions 4 to change the direction of fluid flow.

Anodes 5 are located between sections I and 2 in the form of rods, each of which is enclosed in tube 6. The tubes are connected between each other and the side walls of the core 7 so that the cavity in which the anodes are located forms a continuous partition with an opening between the tubes at the bottom to transfer fluid from / to section 2.

Above the mesh cathode 5 there is a wire mesh 9 limiting the circulation of fluid into the space between the mesh and the cathode. The device 10 serves to ensure that before emptying the container at the end of the work, the liquid in the tubes and undergoing electrolysis and oxygenation is not mixed with the rest of the liquid.

The proposed apparatus can find wide application, first of all, for clarification of fruit juices and other food fluids.

Subject invention

An apparatus for clarifying a fluid with a constant electric current, made in the form of a vessel with sections and an internal lereborkoy equipped with an anode in the form of rods and a cathode in the form of a grid, characterized in that, in order to carry out the electrolysis process without contact with the clarified liquid, the anode rods are inserted into tubes of electrically insulating material, mounted in the inner septum of the vessel, and the cathode is separated from the main mass of the clarified liquid with a wire mesh.
