摘要： A dehumidifying tower having a washing section, a flash-distilling section, and a condensing section. In the washing section, exhaust gas is washed with a cooling liquid to remove at least a portion of solid dust entrained in the exhaust gas, cool the exhaust gas, and condense at least a portion of moisture in the exhaust gas into liquid. The flash-distilling section flash-distills the cooling liquid used in the washing section to produce a cooled cooling liquid and a cooling liquid vapor. Cooling liquid produced by flash-distillation enters the washing section. The flash-distilling section is in gas-phase isolation from the washing section. The condensing section condenses the cooling liquid vapor produced by flash-distillation. The condensing section is configured to be in gas-phase communication with and liquid-phase isolation from the flash-distilling section, and be in both gas-phase and liquid-phase isolation from the washing section.

摘要： A system and method for improving the water quality of a dehydration tower in a purified terephthalic acid device includes a dehydration washing device, a tail gas condensation device communicating with the top of the dehydration washing device, and a water separation device communicating with the tail gas condensation device. The system reduces energy consumption. The tail gas condensation device uses low-pressure vapor of about 0.05 MPa generated by an Nm-th-stage condenser as a heating medium. Working media are water and the low-pressure vapor, and no organic phase is involved in a process, and a reaction is stable and intrinsically safe. The water in the water separation tower is purified water and concentrated water, the purified water is returned to the top of the dehydration tower, and the concentrated water is mixed with a mother liquor and then enters the dehydration tower.
