A sintering energy-saving waste heat power generation flue gas valve is characterized by comprising a labyrinth seal ring, a valve body, a valve plate, a valve shaft and an ash blowing opening, wherein the labyrinth seal ring is connected with the valve body; the valve plate is vertically placed, and one end of the valve plate is connected with the labyrinth seal ring; and the ash blowing opening is formed in the bottom. The sintering energy-saving waste heat power generation flue gas valve is simple in structure, light in weight, good in sealing performance and low in cost, and has the advantage that pipeline deformation cannot be caused; meanwhile, the labyrinth metal sealing butterfly valve adopts an external self-lubricating bearing, the labyrinth sealing system cannot be abraded when used for a long time, and dust accumulated on the labyrinth wall is easy to clean, so that maintenance in the future is more convenient; as the ash blowing opening is formed in the bottom of the valve, dust accumulated at the bottom of the valve can be cleaned, and accordingly, the valve can be normally opened and closed; and the labyrinth metal sealing butterfly valve fully draws technological requirements into consideration and designed with respect to the working conditions and medium properties, is low in cost and is more suitable for being used for sintering waste heat power generation high-temperature flue gas.
Description
technical field [0001] The invention relates to mineral sintering equipment, in particular to a sintering energy-saving waste heat power generation flue gas valve, which belongs to the field of mineral equipment. Background technique [0002] The existing sintering process consumes a lot of energy, and the average energy consumption per ton of sintered ore is 20 kg higher than the standard butterfly, resulting in low efficiency. The energy consumption of the sintering process accounts for about 10% to 12% of the total energy consumption of metallurgy, and its emissions The waste heat accounts for about 49% of the total energy consumption. In the process of sinter production, especially when the sinter is cooled by the blast ring cooler, a large amount of low-temperature flue gas with a temperature of 250-400°C will be discharged, and its heat energy is about 30% of the heat consumption of the sinter. Realize the high efficiency and economic perspective analysis of energy ca...
