Technical Research on Liquid Effluent Converted to Gas Discharge of Nuclear Facilities in the Area Lacking Receiving Water
Discharge control of liquid effluent is a crucial concern in the operation of nuclear facilities located in areas without access to receiving water.To achieve the objective of minimizing liquid effluent discharge from inland nuclear facilities,one approach involves converting the liquid effluent into gas and releasing it through atmospheric dilution.This study aims to investigate the emission regulation of an integrated belt-carrying tower for transporting liquid and converting it into a gaseous state.During the study,the process route of liquid effluent to gaseous state was designed and the liquid-to-gas experimental platform of the project was built to explore the process operation parameters.The research shows that different gas or liquid fluid flow,temperature and external natural conditions in the carrier tower have obvious effects on the processing capacity of liquid-to-gas conversion.Different operating parameters will change the evaporation rate,the effective contact area of the gas-liquid two-phase,the upper limit of the unit gas carrier band and the equipment carrier band rate,and then affect the equipment carrier band capacity.The engineering bench test shows that when the total area of multiple trays in the tower is about 60 m2,the maximum carrying capacity of liquid effluent is about 50 kg/h,and the annual processing capacity is more than 100 m3.
