Description

Technical Field

[0001] The utility model relates to the technical field of calcium chloride tailings wastewater recovery, in particular to an ore wastewater recovery dryer. Background Art

[0002] Calcium chloride is a chemical substance composed of chlorine and calcium, with the chemical formula CaCl2, and is slightly bitter. It is a typical ionic halide, white, hard pieces or granules at room temperature. Its common applications include brine used in refrigeration equipment, road deicing agents and desiccants. Calcium chloride tailings need to be cleaned. Since calcium chloride is easily soluble in water, the wastewater it produces contains a large amount of calcium chloride, so we need to recycle and dry it to avoid resource waste;

[0003] In this regard, a Chinese invention patent with publication number CN113816445A discloses a method for treating wastewater containing calcium chloride formed by rare earth extraction and separation, comprising the following steps: firstly taking wastewater containing calcium chloride formed by rare earth extraction and separation, placing it in a reaction container, wherein the calcium chloride concentration of the wastewater containing calcium chloride formed by rare earth extraction and separation is greater than 2 mol / L, then adding 98% concentrated sulfuric acid to the reaction container to form a wastewater solution containing hydrogen chloride gas and calcium sulfate precipitation, wherein the ratio of the amount of calcium chloride to the amount of sulfuric acid is 0.8-0.95, the temperature of the solution during the reaction of the concentrated sulfuric acid and the wastewater containing calcium chloride formed by rare earth extraction and separation is 60-80°C, the reaction time is 30-150 minutes, and the pressure of the reaction container during the reaction is 0.03-0.05Mpa. The present invention has the characteristics of being able to directly recover hydrogen chloride gas that can be used to prepare pure high-concentration hydrochloric acid;

[0004] There is no detailed dryer for recycling calcium chloride wastewater. During the drying process, calcium chloride is easily adhered to the bottom of the dryer after drying, which is difficult to collect.
