Apparatus to continuously generate hydrates under action of electrostatic atomization

Abstract

The invention discloses an apparatus to continuously generate hydrates under the action of electrostatic atomization. The apparatus comprises a reactor with an outer water jacket, a gas supply unit, amist supply unit which supplies an ionic polymerization inhibitor and water mist to the reactor, a temperature control unit, a hydrate filtration and collection unit connected with the reactor and the mist supply unit, and a data acquisition and processing unit for acquiring and recording temperature and pressure of the rector. The mist supply unit includes a solution tank to hold an ionic surfactant solution, a solution tank valve, a solution pump, a solution incoming valve, a direct-current power source, an atomizing chamber and a loop wire tube; inclined filter plates in multiple tiers andhaving different porosity levels are arranged in the hydrate filtration and collection unit; efficient solid-liquid separation is achieved in bouncing and particle size modes. The defects are overcome that, for instance, hydrate generation in a conventional hydrate generator is incomplete, residue is left in mechanical stirring blades or magnetons, and the reaction process is discontinuous. The apparatus is capable of generating complete and uniform gas hydrates, so that gas storage and transport efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of continuous and rapid preparation of gas hydrates, in particular to a device for continuously generating hydrates under the action of electrostatic atomization. Background technique [0002] Gas hydrate is an ice-like cage compound formed by gas molecules (such as methane, carbon dioxide, hydrogen sulfide, etc.) and water molecules under low temperature and high pressure conditions. In recent years, with the deepening of gas hydrate research, it has been found that the use of gas hydrate for gas separation, storage and transportation can become a new and efficient industrial technology. [0003] In the research, it was found that various existing stirring technologies and solid-liquid separation technologies cannot effectively promote the continuous formation of hydrates. For example, internal mechanical stirring and magnetic stirring will not only cause the formation and agglomeration of hydrates at the ...

[0003] In the research, it was found that various existing stirring technologies and solid-liquid separation technologies cannot effectively promote the continuous generation of hydrates

For example, internal mechanical stirring and magnetic stirring will not only cause the formation and agglomeration of hydrates at the air-water interface and the interface of the stirring equipment, but cannot complete the task of stirring and mixing, hindering the continued formation of hydrates, and there is also the problem that the stirring equipment and the generated hydrates cannot be separated.
