Example Embodiment
[0016] The embodiment of the present invention: such as figure 1 As shown, a method for recycling industrial waste salt includes the following steps: (1) Compatibility of waste salt containing higher ammonium chloride and waste organic salt, and the ratio of the two is determined by pyrolysis test to make it The pyrolysis temperature is 300-350℃, the ratio of ammonium chloride waste salt and organic waste salt in this example is 3:2; (2) Take 300KG ammonium chloride waste salt and 200KG organic waste salt and mix them In the incinerator, pyrolyze at 350℃ for 2 hours to remove organic matter; (3) Cool down, weigh 300KG of waste salt after pyrolysis, add 1200L of water, stir and dissolve to prepare a solution; (4) Filter the solution , Get the clear liquid, evaporate to obtain the mixed salt solid 270KG; (5), prepare 5 cans of 500L saturated sodium chloride solution, the serial numbers are 1, 2, 3, 4, 5, weigh the same batch of mixed salt 100KG and add to the first Stir in 1 tank...
