摘要： PURPOSE:To provide a novel in-furnace suspended matter discharging device free from problems in the sealing parts, etc., of the in-furnace suspended matter discharging device for which a screw conveyor is used for the purpose of discharging the suspended matter on the in-furnace melt of a zinc smelting device to outside the furnace. CONSTITUTION:This in-furnace suspended matter discharging device consists of a scraping section which scrapes the suspended matter to a pump sump section and a discharge section which discharges the suspended matter outside from this pump sump section. This scraping section consists of a scraping plate which is put into and out of the melt via the condenser side wall aperture in the pump sump section, a guide for determining the operation locus of the scraping plate and a driving mechanism 4 for moving the scraping plate. The discharging section consists of a discharge plate, a guide for determining the operation locus of the discharge plate and driving mechanisms 12, 14 for moving the discharge plate.

摘要： PURPOSE:To operate a reducing furnace using a flash furnace as a reducing furnace without any danger of carbon monoxide explosion when the furnace is started or stopped. CONSTITUTION:The carbon monoxide concn. in the waste gas at the outlet of a condenser is controlled to a desired value between 0 and 13%, a raw material is charged into a reducing furnace in the amt. necessary to keep the heat balance of the furnace, and operation is started. The operation is shifted to the normal operation condition after the concn. in the waste gas at the condenser outlet is stabilized. When the operation is stopped, the carbon monoxide concn. in the waste gas at the condenser outlet is stabilized at a desired value between 0 and 13%, and the operation is stopped. Since the infiltration of the atmosphere into the system due to the fluctuation of the gas pressure in the system is prevented when the operation is started or stopped, the explosive combustion of carbon monoxide is surely prevented.

摘要： PURPOSE:To recover the valuable metals in electric furnace dust at a high grade and low cost. CONSTITUTION:The valuable metals are reduced by mixing 5 to 20% fluorite and 3 to 30% carbonaceous reducing agent with the electric furnace dust and indirectly heating the dust at 1400 to 1500 deg.C in a nonoxidative reduction treating furnace 20 in which hermeticity is maintained. After molten iron and slag are recovered, the evaporated metal vapor is introduced to a filter 30 where the iron and lead are recovered. Further the metal vapor is introduced to a condensor 34 and zinc is condensed and recovered at 490 to 520 deg.C; in succession, the metal vapor from this condenser 34 is introduced to a trap 60 and cadmium is condensed and recovered. The efficient reduction of the valuable metals by the indirect heating at 1400 to 1500 deg.C in the reduction treating furnace 20 is enabled by the combined addition of the fluorite with the graphite. The molten iron recovered in such a manner has the high grade. Since the iron and the lead are recovered from the metal vapor in the filter 30, the zinc having the excellent grade is recovered in the condenser 34.

摘要： PURPOSE:To provide a metal vapor condenser with its heat loss reduced by passing a metal bath in a splash chamber through a skimming tank, a cooling tank and a casting tank and then returning the bath to the splash chamber. CONSTITUTION:A reduced medium-boiling-point metal vapor is introduced into a splash chamber 11 from a gas inlet 16 along with a reducing gas, and a rotor 30 is arranged at the center of the chamber 11, partly dipped in a metal bath and rotated in direction of the arrow C by a motor 31 to form a metal bath flow. Consequently, the metal bath in the chamber 11 is splashed, and the introduced medium-boiling-point metal vapor is brought into contact with the splash, absorbed and condensed in the metal bath as the molten metal. The bath is passed successively through the skimming tank 12, cooling tank 13 and casting tank 14 via communicating ports 21, 22 and 23 and then returned to the chamber 11 from a communicating port 24 to recover the medium-boiling-point metal with high heat efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a lead splash condenser facility that can enhance the efficiency of a condenser, which is the efficiency in collecting zinc, while inhibiting the space from being blocked and splashed lead from being carried to the outside of the system to be lost.
SOLUTION: The lead splash condenser facility has double row and plural stages of double-throw type rotors (9a to 9d) and at least two stages of baffle plates (11 and 12) arranged in the gas space in which molten lead droplets fly. The first baffle plate (11) is arranged in an upstream side of the lead splash rotor (9d) of the last stage, which is placed in the gas duct side of a main body of the condenser (3), and is formed so that the gas can flow between the sidewall and itself. The second baffle plate (12) is arranged in a downstream side of the lead splash rotor (9d) of the last stage, and forms an opening in a central part in the width direction of the main body of the condenser (3), by extending two members from the sidewall in a vertical direction to the sidewall.
