Abstract
The invention discloses a purification device and a purification method for flue gas during molybdenum concentrate drying. The purification device comprises a monitoring device, a first purification mechanism, a second purification mechanism and a third purification mechanism; the first purification mechanism comprises a spiral dust collector, a primary exhaust pipe and a primary dust collecting box; a first spray mechanism is arranged on the spiral dust collector; and a second spray mechanism is arranged on the primary exhaust pipe; the second purification mechanism comprises a centrifugal dust collector, a secondary dust collecting box and a cooler. The purification method comprises the following steps: 1, primary purification treatment of the flue gas during molybdenum concentrate drying; 2, secondary purification treatment and cooling; 3, tertiary purification treatment; and 4, flue gas emptying. The purification device and the purification method, disclosed by the invention, havethe benefits that the purification treatment of the flue gas during molybdenum concentrate drying can be simply, conveniently and quickly completed; and oily medicines and molybdenum concentrates in the flue gas are recycled, so that the molybdenum concentrate recovery rate is improved, and the ore-dressing cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of flue gas purification when molybdenum concentrate is dried, and in particular relates to a flue gas purification device and method for drying molybdenum concentrate. Background technique [0002] The production of high-purity molybdenum disulfide by molybdenum chemical industry has high requirements on the quality of molybdenum concentrate as raw material. It is required that the molybdenum grade in the molybdenum concentrate should not be less than 57%, and the carbon content should not exceed 0.5%. The produced 57% molybdenum concentrate has a carbon content of more than 2% after dehydration, which cannot meet the quality. Therefore, the molybdenum concentrate is dried at high temperature to reduce the carbon content in the molybdenum concentrate. The drying temperature is about 400°C. The flue gas produced in the process of concentrating contains some molybdenum concentrate and beneficiation oil partic...
