Solid-liquid separating device and separating method

Abstract

The invention discloses a solid-liquid separating device and a separating method. The solid-liquid separating device at least comprises a solid-liquid mixture holding component, an elastic porous adsorption component, an extruding component and a support component, wherein the solid-liquid mixture holding component is used for storing or conveying an unseparated solid-liquid mixture; the elastic porous adsorption component is made of a plurality of capillary tubes, is arranged on the solid-liquid mixture holding component, and is in contact with the mixture; the extruding component is used for extruding the elastic porous adsorption component; and the support component is used for supporting the elastic porous adsorption component when the elastic porous adsorption component is extruded by the extruding component, and is a porous component. By adopting the solid-liquid separating device and the separating method, solid-liquid separation can be realized without adding a large quantity of substances such as flocculating agents or introducing a large amount of mechanical energy, so that the energy consumption is low, and the treatment cost is low.

Description

technical field [0001] The present invention relates to the concentration, separation and collection of solid-liquid mixtures, in particular to a solid-liquid separation method and device powered by capillary force. The capillary force is used as the main force to realize the concentration and solid-liquid separation of the continuous process of solid-liquid mixture. Background technique [0002] The process of separating solid and liquid from a solid-liquid mixture is called solid-liquid separation. There are many methods of solid-liquid separation, such as sieve, sedimentation, flotation, filtration, membrane filtration, pressure filtration, vacuum, centrifugation and other means. The principle is to use the density difference between solid particles and liquid or use mechanical force to let the liquid phase pass through the filter medium and the solid phase material is retained by the filter medium. In order to achieve or increase the above effects, it is necessary to i...
