Problems solved by technology

Although this invention is a gas-solid mixer, it is a gas-solid hybrid nano-refrigerant charging device in the field of refrigeration. It does not involve gas-solid mixing and two-phase flow mixing. It is a completely different technical field. It mainly uses diffusion effects and pressure differences. , but gas-exchange membranes are very expensive, resulting in reduced system economics

Abstract

The invention relates to a nanometer gas sol generator, and belongs to the technical field of efficient gas-solid mixing equipment. The nanometer gas sol generator comprises a Chaos cyclone mixer, a jet flow device, a support post and a base, wherein the Chaos cyclone mixer and the jet flow device are coaxially communicated; the Chaos cyclone mixer is fixedly arranged on the base through the support post; the Chaos cyclone mixer comprises a high-speed nitrogen gas spray pipe, a methanol steam flow inner cavity, an original gas-solid mixed flow inner cavity, a gradual reduction acceleration spray pipe, a dustproof dust suction cover, a nitrogen gas pipe, a methanol steam pipe, a mixing chamber and an original gas solid mixed flow input pipe. The nanometer gas sol generator provided by the invention can reduce the agglomeration and deposition of ultrafine particles, so that the gas-solid mixing is more uniform; the reaction efficiency is greatly improved; in addition, the structure of the generator is simple; the automation degree is high; the generator can be used for performing nanometer grade particulate multiphase mixed flow in an efficient clean simple convenient and low-cost modes.

Description

technical field [0001] The invention relates to a nano-aerosol generator, which belongs to the technical field of high-efficiency gas-solid mixing equipment. Background technique [0002] At present, the existing mixers are mainly aimed at gas-liquid mixers, there are few gas-solid mixers and three-phase flow generators, and there is no mixed multi-phase flow generator that is compatible with solar thermochemical reactors , the existing ones are only simple mixing similar to the three-way pipe, without considering the problem of particle agglomeration and agglomeration, and the uniformity of particle distribution is relatively poor, prone to explosion caused by overtemperature and overpressure, and the degree of automation is relatively low. [0003] When the existing gas-solid mixer is used in experiments or production, it will cause a lot of dust and agglomeration during transportation and mixing, and due to the compact structure, the mixing is often not very sufficient, r...
