Description

technical field [0001] The invention relates to the technical fields of energy power and chemical production, and specifically relates to a multi-field cooperative microwave liquid phase constant temperature desorption integrated system. Background technique [0002] In industrial production, especially in the fields of energy power and chemical engineering technology, it is necessary to desorb liquid objects (liquid phase) to obtain gas products, and to discharge or utilize the obtained gases according to the purpose of their production. For example, the wine making industry needs to desorb light liquor to extract ethanol; the thermal power production industry needs to desorb and deoxygenate boiler feed water; the wet regeneration flue gas desulfurization industry needs to desorb desulfurized rich liquid to obtain SO 2 And regenerate the desulfurization liquid. In order to improve the desorption yield and optimize the desorption performance, it is necessary to solve the de...

Problems solved by technology

[0003] The liquid-phase desorption method in the prior art mainly strengthens desorption through pure heat or supplemented by steam stripping. Although the desorption system is relatively mature, the desorption performance is limited by chemical dissociation and mass transfer capacity, so there is a problem of unsatisfactory desorption performance. ; In view of the fact that the existing technology promotes chemical dissociation through microwave special effects, ultrasonic cavitation gas entrainment, negative pressure promotes gas detachment and liquid phase boiling evaporation stripping, microwave, ultrasonic, negative pressure and liquid phase boiling evaporation multi-field Synergistic promotion of desorption performance is an effective approach

After searching, although independent microwave, ultrasonic, negative pressure and liquid phase boiling evaporation process systems are all applied, there is no public publication on the process system of multi-field synergy and application in liquid phase desorption, especially the solution to meet the desorption requirements. There are not many methods for microwave liquid phase constant temperature desorption process system
