Embodiment 1
[0044] This example provides a plurality of test samples, all test samples 1, 2 and 3 are respectively taken from different chlorinated blocks produced by de-F and CI of sub-zinc oxide, and each temperature test is that the samples are heated from room temperature to After drying the moisture at 200 °C, continue to heat up to the required temperature and calcinate at a constant temperature for 30 minutes. The slag rate test is completed in a muffle furnace, and the flue gas receiving test is completed in a tubular electric furnace equipped with a flue gas receiving device.
[0045] Among them, the quantitative test of zinc chloride is detected by EDTA titration method, AAS method or icp method;
[0046] The quantitative test of ammonium chloride is detected by NaOH titration;

The invention discloses a pyrogenic separation method of chloride, which comprises the following steps: step 1, placing a material containing ammonium chloride, zinc chloride, potassium chloride and sodium chloride in a rotary kiln, heating at a temperature higher than the boiling point of ammonium chloride but lower than the boiling point of zinc chloride, volatilizing ammonium chloride in the material to form smoke, cooling and collecting ammonium chloride in the smoke; 2, continuously heating the solid substance calcined in the step 1 at a heating temperature higher than the boiling point of zinc chloride but lower than the boiling point of potassium chloride, volatilizing zinc chloride in the material to form smoke, cooling and collecting zinc chloride in the smoke; and 3, feeding the solid substance calcined in the step 2 into a potassium chloride and sodium chloride wet separation system to separate potassium chloride, sodium chloride and other components in the solid substance. The pyrogenic separation method of the chloride aims to solve the problems of high production cost and incomplete separation in the existing wet separation of the chloride in industrial byproducts.
Description
technical field [0001] The invention relates to the technical field of industrial waste recycling, in particular to a pyrolysis method for chlorides. Background technique [0002] During the smelting process in the non-ferrous industry, by-products containing certain components of zinc chloride, ammonium chloride, sodium chloride, potassium chloride and other soluble salts will be produced. At present, this part of chlorides can only be separated by wet separation. The properties of soluble salts such as zinc chloride, ammonium chloride, sodium chloride, and potassium chloride in solution are relatively similar. It is difficult to completely separate them by wet separation, and multiple component conversions are required. The problem of producing industrial-grade (battery-grade) zinc chloride is that only products with lower purity can be obtained, and the actual income is relatively low. Therefore, most of the by-products containing chlorides are finally treated as industri...
