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

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...
