Energy-saving and environment-friendly mercury metallurgy electromagnetic induction roasting rotary kiln with size of phi 2000*18 meters

Abstract

The invention relates to an energy-saving and environment-friendly mercury metallurgy electromagnetic induction roasting rotary kiln with the size of phi 2000*18 meters. The energy-saving and environment-friendly mercury metallurgy electromagnetic induction roasting rotary kiln comprises a kiln head cover, a mercury ore feeding hopper, a high-temperature alloy steel inner container kiln barrel, a wheel belt, a movable carrier wheel group, a transmission device, a gear pair, a fixed carrier wheel group, a track and cement piles. The energy-saving and environment-friendly mercury metallurgy electromagnetic induction roasting rotary kiln has the advantages that the energy is clean, and the problems that a mercury metallurgy rotary kiln roasted by a coal furnace is low in production efficiency, severe in environmental pollution, high in energy consumption and the like is solved. The energy is used and distributed conveniently. Compared with a mode of heating by fuel, gas and the like, the heating mode of the energy-saving and environment-friendly mercury metallurgy electromagnetic induction roasting rotary kiln has the characteristics that heat efficiency is high, sensible heat is not taken out by smoke or ash, and a kiln body is simple and compact in structure, small in heat dissipation area, low in heat dissipation loss, easy to control and regulate automatically and high in kiln temperature control precision, and meets requirements of a narrow calcining temperature process. The production efficiency is high, energy consumption is reduced, and emission of environmental pollutants is reduced. The energy-saving and environment-friendly mercury metallurgy electromagnetic induction roasting rotary kiln is an innovation of energy conservation, environmental protection and an equipment technology of a mercury metallurgy kiln.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly electromagnetic induction roasting rotary kiln for mercury smelting, in particular to an energy-saving and environment-friendly mercury smelting electromagnetic induction roasting rotary kiln with a diameter of φ2000×18 meters, which belongs to the technical field of mercury metal smelting equipment. Background technique [0002] Mercury mines in China are mainly distributed in eastern Guizhou and western Hunan. The proven resources of mercury mines are second only to Spain, ranking second in the world. "Ming History Shihuo Zhi" records that there is a mercury cinnabar site in Dawanshan, Guizhou. Based on this, it can be deduced that mercury mining in this area has a history of at least 600 years. Modern mercury mining began at the end of the 19th century. In 1899, British and French businessmen established the "Anglo-French Mercury Company" in the name of running a mine with a loan, and...
