Patent number: 7232504Abstract: A distilling apparatus and method use a two step distillation and purification process for processing a waste liquid, such as an impure sulfuric acid solution, to form a highly concentrated sulfuric acid solution. First, the waste liquid is stored in a concentrating column, where it is heated. A condenser, which uses the waste liquid as a cooling medium, condenses the vapor generated by the heater. The condensed vapor is passed through a filter, which separates impurities out of the waste liquid, prior to feeding the waste liquid back into the concentrating column. Water is then removed from the waste liquid via a distilling process. The resulting concentrated liquid is then fed to a purifying column, where it is again heated, to remove residue, and condensed, resulting in a highly pure waste liquid.Type: GrantFiled: November 22, 2002Date of Patent: June 19, 2007Assignee: Fujitsu LimitedInventors: Hiroshi Osuda, Toru Matoba, Daisuke Adachi, Masataka Fukuizumi

Patent number: 5271810Abstract: A distillation device for separating a liquid mixture from contaminants contained therein. The device partially cools, using an air radiator or equivalent passive heat-exchange device, a fluid of that contains at least one component of the mixture to be separated; the temperature of the fluid does not fall the ambient air temperature, thus preventing condensation on the heat exchanger. The partially cooled fluid is introduced into an aspirator and combined therein with a gaseous stream produced by heating the mixture to boiling in a separate chamber. Because of the high surface area of contact between vapor and aspirated liquid, the heat transfer is completely effective to condense the gaseous mixture, which settles into a pool. The components can then be separated mechanically or by gravity.Type: GrantFiled: June 19, 1992Date of Patent: December 21, 1993Assignee: Environmental Solvents CorporationInventors: Gene E. Keyser, Robert L. Klopfenstein

Patent number: 4957200Abstract: A water distillation apparatus has an outer chamber and an inner chamber suspended within the outer chamber by support arms. The inner chamber suspends a heating element to create steam. Heat is transferred from the inner chamber to the outer chamber, wherein the heated water in the outer chamber is allowed to degassify. Degassification removes unpleasant tasting chemicals from the water before distillation. Openings are provided for air circulation to remove the gasses. A condenser is also suspended by the support arms. The stem exits the inner chamber and goes into the condenser. A fan provides air circulation through the condenser. The outer chamber is not penetrated by any openings, thereby precluding the possibility of any leaks. The support arms bear on the outer chamber walls; the inner chamber is removed from the outer chamber for cleaning simply by lifting up. In one embodiment the outer and inner chambers are made of a ceramic material to better regulate heat transfer.Type: GrantFiled: December 28, 1989Date of Patent: September 18, 1990Inventors: William F.

Patent number: 4561940Abstract: The overcharge prevention device is installed in a solvent processing plant in a vacuum evaporator of a heat exchanger. It assures that the level of the cleaning solution in the vacuum evaporator cannot randomly rise when a feed valve malfunctions. A float body of an overcharge valve extending into the vacuum evaporator exerts a pressure through a double-arm lever and a valve plunger upon a ball valve and a valve seat in normal operation and holds the overcharge valve in a closed position. As the level of the cleaning solution undesirably rises, the buoyant action of the cleaning solution acts on the float body, causing the pressure on the valve seat to diminish, and the overcharge valve opens. This permits air to enter into the vacuum evaporator through the overcharge valve. The generated vacuum collapses and the suction force employed to ingest the cleaning solution disappears.Type: GrantFiled: July 9, 1984Date of Patent: December 31, 1985Assignee: Mentec AgInventor: Rene Meier
