Abstract
The invention discloses a single-cycle two-stage gas dissolving system and a gas dissolving method thereof. The single-cycle two-stage gas dissolving system comprises a main pipeline, as well as a circulation pump and a gas dissolver which are sequentially communicated with the main pipeline, wherein the gas dissolver comprises a primary gas dissolver and a secondary gas dissolver sequentially communicated with the main pipeline; a primary gas dissolver gas inlet pipe opening is formed in the bottom of the primary gas dissolver; the bottom of the secondary gas dissolver is communicated with an external gas supply pipe through a gas inlet pipe; a liquid inlet of the main pipeline is communicated with an external liquid supply pipe; a liquid outlet is communicated with a separation tank; a gas outlet pipe opening is formed in the top of the separation tank, a liquid inlet pipe opening is formed in the middle, a liquid outlet pipe opening is formed in one side of the bottom, and a detection pipe opening is formed in the other side of the bottom; the liquid inlet pipe opening is communicated with the main pipeline; a residual gas pipe is communicated between the gas pipe opening of the separation tank and the primary gas dissolver gas inlet pipe opening of the primary gas dissolver. The invention solves problems that the conventional gas dissolving equipment requires a large reaction container or a high operating pressure, only performs the gas dissolving operation process once, and has relatively low gas dissolving efficiency.
Description
technical field [0001] The invention relates to an air-dissolving process, in particular to an air-dissolving system and an air-dissolving method thereof. Background technique [0002] In industries such as chemical industry, food and water treatment, a large amount of dissolved gas process equipment is required, and various gas-liquid mixing reactors are most commonly used. The key to affecting the efficiency of dissolved gas is to dissipate the gas to be dissolved at the minimum energy cost. Microbubbles and fully turbulent liquid flow. Existing various types of air-dissolving equipment mostly use bubbling, spraying or pressure-dissolving air-dissolving methods, and air-dissolving equipment that uses bubbling, spraying or pressure-dissolving air usually requires a larger reaction vessel or higher working pressure, and The air-dissolving equipment using bubbling, spraying or pressure-dissolving air usually only has one working process of dissolving air, and the efficiency ...
