Dear everyone! Does anyone have a demister installed in their phosphate concentration evaporator? What type of demister is used, and what is its effectiveness?
In any evaporator, whether it is a concentration evaporator or a multi-effect evaporation crystallizer MVR, a demister that prevents crystallization-induced blockages, features high separation efficiency, high operational flexibility, and low operating and maintenance costs must be installed before the secondary steam outlet. It is recommended to use the G50 type air-liquid high-efficiency demisting and defoaming separation element; wire mesh should never be used. For reference: 1. Regarding the issue of excessive ammonia nitrogen levels caused by the secondary steam collected from the top of the sulfuric acid AN multi-effect evaporation crystallizer carrying ammonium liquid droplets, please visit http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1565169 to participate in the discussion. 2. For measures to evaporate and concentrate the mixed dilute acid produced by catalytic devices using mixed binary strong acids such as sulfuric acid/phosphoric acid/nitric acid or tertiary strong acids, please visit http://bbs.hcbbs.com/thread-1627353-1-1.html to participate in the discussion. 3. Regarding methods to prevent secondary steam from carrying foam droplets into the steam compressor in MVR evaporators for wastewater containing salts and organic high-boiling-point substances, please visit http://bbs.hcbbs.com/thread-1633997-1-1.html to participate in the discussion. 4. For a case study and discussion on the lack of design for the secondary steam baffle demister in MVR evaporators contracted by a certain university, please visit http://bbs.hcbbs.com/thread-1634858-1-1.html to participate in the discussion. 5. For measures to achieve efficient gas-liquid separation and foam removal of the secondary steam in the concentration, evaporation, and crystallization units used by salt and soda production enterprises, please visit http://bbs.hcbbs.com/thread-1636042-1-1.html to participate in the discussion.
