Liquid degassing device and method capable of automatically and continuously providing degassed liquid

Abstract

The invention discloses an automatically-operated liquid degassing device for continuously providing degassed liquid. The automatically-operated liquid degassing device is composed of a vacuum system,a protective gas system, a degassing system, a liquid storage and transfer system and a control system; the control system drives the liquid storage and transfer system through a preset procedure toinject pretreated liquid into degassing tanks, a vacuum tank of the vacuum system communicates with the degassing tanks of the degassing system, the temperature and the pressure in the degassing tanksare adjusted to enable gas to escape quickly, and the gas is discharged by the vacuum system; the protective gas system can input protective gas into the degassing tanks; and the degassing system isprovided with the two or more degassing tanks which work by turns, and it is ensured that the device can output the degassed liquid sufficiently, stably and continuously. The automatically-operated liquid degassing device can be widely applied to the processes such as steam boiler water-supplying deoxygenation and degassing before filling of liquid beverage, the larger the treatment amount is, themore prominent the effects of low energy consumption, high removal rate and high degassing speed are, the operation automation degree is high, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of liquid treatment equipment, and relates to the link of liquid degassing, in particular to a device for physically degassing liquid containing gas. Background technique [0002] Although the current liquid degassing technology and equipment have various names and appearances, except for chemical methods, they are basically related improvements around pressure and temperature, and the principle is Henry's law. For example, boiler feed water deaerators are widely used. The traditional thermal deaerator is to send softened water into the deaerator head of the deaerator and form a film or spray shape, and at the same time pass steam into the deaerator head. Make the demineralized water fully contact with the steam in the deaerator head and heat it up to near boiling point, so that the gas in the demineralized water escapes to complete the deoxidation. This kind of deaerator must supply steam continuously durin...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the defects of the degassing device in the prior art that the vacuum pump needs to run continuously during the degassing process, and requires a high-power vacuum pump, and provide an automatic and continuous vacuum pump that does not need to run continuously during the degassing process. Provide liquid degassing device and method for degassing liquid
