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 invention relates to an aqueous solution treatment technology, in particular to a method and device for treating an aqueous solution by adopting a hydrate method. Background technique [0002] In many fields related to chemical industry, we often encounter the treatment technology of aqueous solution, and there are many kinds of objects and purposes of treatment. For example, the excess water in the solution is removed so that the aqueous solution is concentrated; the separation operation of some special aqueous solutions is implemented to Obtain high-quality water, such as the desalination of seawater and the production of pure water. At present, the most common methods used are evaporation, filtration (including the application of membrane technology), etc. Since the use of various technical means has certain limitations, it also encourages people to hope to find and develop more processing technologies to suit Different environments and requirements,...
