Definitions
- the present invention relates to a heavy metal removing apparatus and a cement manufacturing system, and more particularly to an apparatus for removing heavy metals contained in exhaust gas from a cement manufacturing system.
- wastes used as cement raw materials and calcined fuel contain heavy metals such as municipal waste incineration ash, various sludges, coal ash, and construction soil, so the amount of heavy metals brought into the cement production system There is concern about the increase.
- mercury, zinc, selenium, chlorides thereof and the like are volatilized in the high temperature part (for example, rotary kiln, preheater, etc.) of the cement manufacturing system and are contained in the exhaust gas. Thereafter, as the temperature of the exhaust gas decreases, these heavy metals are deposited on the surface of the dust contained in the exhaust gas, or become fine particles of the heavy metal or its compound itself.
- dusts and fine particles are collected by a dust collector (electric dust collector, bag filter, etc.) provided in the exhaust gas path of the cement manufacturing system and removed from the exhaust gas.
- a dust collector electric dust collector, bag filter, etc.
- mercury is highly volatile and easily gasified at high temperatures, so it is hardly contained in the clinker and is contained in the exhaust gas. It will circulate through the exhaust gas system. For this reason, if there is no means to remove the mercury in the exhaust gas, the concentration of mercury in the exhaust gas will gradually increase as the amount of mercury brought in from cement raw materials increases, increasing the amount of mercury discharged outside the system. Problem arises.
