Power-assisted degassing system, and vacuum degassing tower and pure water system with power-assisted degassing system

Abstract

The invention provides a power-assisted degassing system, and a vacuum degassing tower and a pure water system with the same. The power-assisted degassing system comprises a water seal pump, a gas-liquid separation circulating barrel and a power-assisted pump, wherein the water seal pump is communicated with the upper portion of the degassing tower through a main pipeline and is used for pumping out mixed water gas in the degassing tower, the gas-liquid separation circulating barrel is circularly communicated with the water seal pump through a circulating pipeline and is used for carrying outgas-liquid separation treatment on the mixed water gas pumped by the water seal pump, and the power-assisted pump is arranged on the main pipeline, located between the water seal pump and the degassing tower and used for providing assistance when the water seal pump pumps out mixed water and gas. The water seal pump and the power-assisted pump form two-section type pumping equipment based on mechanical vacuum assistance, the circulating water amount of the water seal pump is small, the needed motor power is small, and the mixed water gas pumped out by the vacuum tower only needs to be treatedby one water seal pump, so that the equipment load is small, and the blade operation efficiency loss degree of the water seal pump is low.

Description

technical field [0001] The present disclosure relates to the technical field of pure water treatment equipment, in particular to a power-assisted degassing system, a vacuum degassing tower having the system, and a pure water system. Background technique [0002] During the middle stage of the pure water system (reverse osmosis to the primary pure water system), it is necessary to remove carbon dioxide (CO 2 ) gas, avoid carbonate (CO 3 2- ) Subsequent process water quality will be affected. Existing pure water systems usually use a vacuum degassing tower system to achieve the above functions, which can isolate external air factors from interfering with water quality. The vacuum degassing tower system must be equipped with a liquid-sealed vacuum pump (the vacuum degree is about 25 Torr to 35 Torr, where Torr is Torr, 1Torr≈1.316×10 -3 standard atmospheric pressure, or 1Torr≈133.322Pa), so that the water quality in the degassing tower system will not be polluted by the out...

Problems solved by technology

Accordingly, all the mixed water gas extracted from the vacuum tower is processed by multiple single-stage water-sealed vacuum pumps, resulting in excessive load and serious loss of operating efficiency of the pump blades.
