Method and apparatus of processing aqueous solution by hydrate method

Abstract

The invention involves a method for water treatment by using a reactor containing a hydrate formation element in the upper. The reactor is divided into a low pressure part in the upper area and a high pressure part in the lower area. The method comprises placing the water to be dealt in the reactor, wherein the water has non-contact surface with the hydrate formation element, compressing hydrate generation gas to a temperature higher than the hydrate generation temperature and then introducing the gas into the reactor through the water solution to be dealt, bringing out steam and forming hydrate on the hydrate formation element, decomposing the hydrate in the low pressure part of the reactor and separating, collecting separated water, and discharging the concentrated solution treated from the bottom of the reactor. The invention also provides a device for the method. The method and device can be used for seawater desalination, medicine solution concentration, and juice or solution fermentation, solve problems of mother liquid carried in hydrate crystal particles, and improve efficiency.

Description

technical field [0001] The present invention relates to the treatment technology of aqueous solution, especially relates to a kind of using hydrate technology to process the aqueous solution, so that the hydrate-generated gas and the entrained water vapor form hydrate and then decompose the hydrate to obtain purified aquatic products or the aqueous solution The technical method and device for thickening belong to the technical field of chemical industry. Background technique [0002] In many fields related to chemical industry, we often encounter the treatment technology of aqueous solution, and there are many objects and purposes of treatment, such as removing excess water in the solution to concentrate the aqueous solution; implementing separation operations for some special aqueous solutions to Access to high-quality water, such as desalination of seawater and production of pure water. At present, the most common methods are still such as evaporation, filtration (includi...
