Retrieve phosphoric pentoxide's device in three formicester liquid waste incinerator of follow emission flue gas

The utility model provides a retrieve phosphoric pentoxide's device in three formicester liquid waste incinerator of follow emission flue gas, includes rapid cooling scrubbing tower (1), clear water scrubbing tower (2), first circulating pump (17), second circulating pump (25) and ejection of compact governing valve (15), flue gas inlet (18) are burned at the top of rapid cooling scrubbing tower, and there is rapid cooling washing liquid shower head (11) on upper portion, and there is circulation cleaning liquid shower (12) at the middle part, the top of clear water scrubbing tower has surplus exhanst gas outlet (26), and upper portion has clear water shower (21), and there is circulation cleaning liquid shower (22) at the middle part, exhanst gas outlet (19) of rapid cooling scrubbing tower feed through with flue gas inlet (27) of clear water scrubbing tower mutually. In this kind of when operation device, the high -temperature exhaust gas that three formicester liquid waste incinerator discharged absorbs through rapid cooling scrubbing tower, the washing of clear water scrubbing tower, retrieves the phosphoric acid liquid of the higher concentration of phosphoric pentoxide production, and remaining flue gas subsequent processing device such as available neutralizing treatment tower is again handled the back and is discharged.
