Abstract

The invention relates to the technical field of mixed gas separation, and particularly relates to a hydration reaction device and a method for separating mixed gas. The hydration reaction device comprises a reactor and a pressure control valve used for controlling the internal pressure of the reactor, wherein the reactor comprises a temperature control shell, a heat conduction partition plate andporous medium filler used for storing generated liquid, the temperature control shell comprises an inner shell connected with the heat conduction partition plate and a phase change heat storage shellattached to the outer side of the inner shell in a surrounding mode, the porous medium filler is arranged on the heat conduction partition plate in a contact manner, a gas inlet and a gas outlet are formed in the temperature control shell, and the pressure control valve is communicated with the gas outlet so as to control the pressure in the reactor. According to the hydration reaction device, theporous medium filler is connected with the phase change heat storage shell through the heat conduction partition plate and the inner shell, and the temperature of the phase change heat storage material can be kept in a stable state while the external temperature changes, so that the temperature of the porous medium filler is also in a stable state, and the hydration reaction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mixed gas separation, in particular to a hydration reaction device. Background technique [0002] With the development of the economy, the demand for various gases in industrial production and human life has increased sharply, and there are specific requirements for the purity of gases. However, most of the gas mixtures produced in nature and industrial production require the application of certain physical or chemical means to separate the desired gas from the impurity gas, which involves gas separation technology. [0003] Gas hydrate is a solid substance formed by gas and liquid under specific temperature and pressure conditions. The formation conditions of different gas hydrates are different. According to this difference, by controlling the temperature and pressure conditions, some components in the mixed gas can be fixed in the hydrate, so as to realize the separation of the mixed gas. Compared wi...
