Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 , figure 2 , image 3 As shown, a circulating fluidized bed degassing device for preparing hydrogen fluoride is characterized in that it includes a multi-stage cyclone separation condenser I1, a circulating fluidized bed degassing tower body 2, a feed liquid connecting pipe 3, a thermostat 4, and a multi-stage cyclone Separation condenser II7, U-shaped liquid sealer 8, feeder 9, liquid receiving tray 10.
[0023] The circulating fluidized bed degassing tower body 2 is divided into upper and lower sections, the upper part is the rectification section, and the lower part is the stripping section. The rectification section is designed with multi-stage cyclone separation condenser I1 and multi-stage cyclone separation condenser II7. The stripping section is designed with a thermostat 4, and the crude hydrofluoric acid li...
