Embodiment 1
[0056] A method for purifying lime-flue gas brine, comprising the following steps:
[0057] 1) Primary reaction clarification: Sampling and analyzing the original halogen, measuring Ca in the original halogen 2+ , Mg 2+ Concentration, according to the amount of original halogen in the primary reaction barrel and the Ca in the original halogen 2+ , Mg 2+ Concentration value calculates the amount of required lime and soda ash, calculates the used reaction reaction equation as follows:
[0058] CaO+H 2 O→Ca(OH) 2
[0059] Ca(OH) 2 +Mg 2+ → Ca 2+ +Mg(OH) 2 ↓
[0060] Ca 2+ +Na 2 CO 3 →CaCO 3 ↓+2Na +
[0061] First, pump the original halogen into the primary reaction barrel, and at the same time, use 60% of the calculated lime amount to pre-feed lime into the primary reaction barrel. During the pre-feeding process, start the agitator in the primary reaction barrel to Stir so that the original brine and lime mix more evenly, stop feeding the original brine when the ...

[0074]A method for purifying lime-flue gas brine, comprising the following steps:
[0075] 1) Primary reaction clarification: Sampling and analyzing the original halogen, measuring Ca in the original halogen 2+ , Mg 2+ Concentration, according to the amount of original halogen in the primary reaction barrel and the Ca in the original halogen 2+ , Mg 2+ Calculating the amount of lime and soda ash required by the concentration value, first pump the original brine into the primary reaction tank, and at the same time use 70% of the calculated lime amount to pre-feed the lime into the primary reaction tank, and start during the pre-feeding process The agitator in the primary reaction tank stirs the original brine so that the original brine and lime can be mixed more evenly. When the liquid level of the original brine reaches the specified liquid level scale, stop feeding the original brine; then add the calculated amount of soda ash to the original brine Adding soda ash, the tim...

[0088] A method for purifying lime-flue gas brine, comprising the following steps:
[0089] 1) Primary reaction clarification: Sampling and analyzing the original halogen, measuring Ca in the original halogen 2+ , Mg 2+ Concentration, according to the amount of original halogen in the primary reaction barrel and the Ca in the original halogen 2+ , Mg 2+ Calculating the amount of lime and soda ash required by the concentration value, first pump the original brine into the primary reaction tank, and at the same time use 80% of the calculated lime amount to pre-feed the lime into the primary reaction tank, and start during the pre-feeding process The agitator in the primary reaction tank stirs the original brine so that the original brine and lime can be mixed more evenly. When the liquid level of the original brine reaches the specified liquid level scale, stop feeding the original brine; then add the calculated amount of soda ash to the original brine Adding soda ash, the ti...
