摘要： The invention relates to a distributor bottom (1), particularly a nozzle-type distributor bottom, for steadily introducing process gas, especially process gas loaded with solid particles, into a process chamber (3), optionally to create a fluidized bed, said process chamber (3) being disposed above the distributor bottom and being formed by walls (4) of a reactor used for metallurgically, particularly thermally, treating feedstock. The inventive distributor bottom is provided with a plurality of holes. Holes are arranged near the walls to prevent substances from attaching to the reactor walls. Special arrangements relate to nozzles and ducts.

摘要： The present invention relates to a method and device for removing dust particles from reducing gas. The method of the present invention comprises a step of providing reducing gas, a step of injecting the reducing gas into a chamber including a sacrificial nozzle therein, and a step of discharging the reducing gas from the chamber. According to the present invention, since low-melting alkali chloride contained in the reducing gas is removed before being blown into a fluidized reducing furnace, the operation rate of the fluidized reducing furnace is improved due to the reduced clogging of the distribution nozzle in the fluidized reducing furnace, and the ore reduction rate is increased and fuel costs are reduced as the temperature of the reducing gas is increased.
摘要翻译：本发明涉及从还原气体除去灰尘颗粒的方法和装置。本发明的方法包括提供还原气体的步骤，将还原气体注入到其中包括牺牲喷嘴的室中的步骤以及从所述室排出还原气体的步骤。根据本发明，由于在吹入流化还原炉之前将包含在还原气体中的低熔点碱金属氯化物除去，所以流化还原炉的运行速率由于流化床中分配喷嘴的堵塞减少而得到改善并且随着还原气体的温度升高，矿石的还原率提高，燃料成本降低。
