Abstract
A system and method for the removal of volatile components from a liquid or a slurry containing solids and liquids and using a screw conveyor or auger system that transfers solid/liquid slurries through an elongated tube heated by solar energy from a parabolic solar trough. The system flashes off the volatile component then counter-currently flows that vapor back into the hollow pipe inside of the augur creating a Multi-effect or Multi Flash device which greatly improves the overall efficiency of removal of the volatile material.
Claims15
A solar powered device for efficient removal of volatile liquids from industrial solid-liquid slurries comprising:
- a. a screw conveyor inside an elongated tube, with the conveying flights of the screw conveyor mounted onto a hollow pipe within the elongated tube;
- b. a first end of the elongated tube comprising a feed port for a solid-liquid slurry;
- c. a second end of the elongated tube comprising a waste drop for removal of the solids material after its liquids have been removed;
- d. wherein the elongated tube is centered in a parabolic solar trough that impinges solar energy onto the elongated tube to volatilize the volatile liquid from the contained slurry;
- e. wherein the elongated tube is not perfectly round but is topped with an enclosed vertical U-shaped or V-shaped top that provides a pathway for the volatile vapor removed from the solid-liquid slurry;
- f. wherein a hollow pipe recycles the volatile vapor removed from the solid-liquid slurry counter-currently back through the hollow pipe within the elongated tube to remove the resulting liquid.
A method for utilizing solar power for efficient removal of volatile materials such as water from industrial slurries comprising:
- a. providing a screw conveyor inside an elongated tube, with the conveying flights of the screw conveyor mounted onto a hollow pipe within the elongated tube;
- b. providing a first end of the elongated tube with a feed port for a solid-liquid slurry;
- c. providing a second end of the elongated tube with a waste drop for removal of solids material;
- d. positioning the elongated tube in a parabolic solar trough that impinges solar energy onto the elongated tube to volatilize the volatile liquid from the contained slurry;
- e. providing an enclosed vertical U shaped or V-shaped top to the elongated tube that provides a pathway for the volatile vapor removed from the solid-liquid slurry;
- f. providing a vacuum at the first end of the elongated tube to pull the flow of volatized vapor from the second end of the elongated tube in a counter-current flow in the hollow pipe of the elongated tube;
- g. providing an exit from the hollow pipe of the elongated tube for removing the liquid of the solid-liquid slurry.
