摘要： The object of the invention is to provide a method of treating wash water resulting from the scrubbing of process gases in smelting plants, according to which method the wash water is brought into intimate contact with the process gas and is circulated when the solids have been deposited. The method according to the invention draws off a partial flow from the wash water, mixes it with fresh water and uses it for rewashing the process gas. According to the invention, the wash water necessary for the scrubbers is drawn from a wash water container. In the sedimentation tank the insoluble portions are removed from the substance-charged wash water which is then introduced into the wash water container. The wash water required for the rewashing stage is removed from the wash water container and mixed with fresh water via the fresh water pipe. Solids are likewise removed in the sedimentation tank from the wash water from the rewashing stage, this wash water then being, circulated after introduction into the wash water container.
摘要翻译：本发明的目的是提供一种处理由冶炼厂中的工艺气体洗涤产生的洗涤水的方法，根据该方法，洗涤水与工艺气体紧密接触并在固体沉积时循环。根据本发明的方法从洗涤水中排出部分流动，将其与淡水混合并将其用于对工艺气体进行再洗涤。根据本发明，洗涤器所需的洗涤水从洗涤水容器中抽出。在沉淀池中，将不溶部分从装有物质的洗涤水中除去，然后将其引入洗涤水容器中。冲洗阶段所需的洗涤水从洗涤水容器中取出，并通过淡水管与淡水混合。固体同样从沉淀池中从洗涤阶段的洗涤水中除去，然后洗涤水在引入洗涤水容器之后循环。

摘要： In a method for producing liquid pig iron or liquid steel pre-products from charging substances comprising iron ore, preferably in lumps or pellets, and optionally fluxes. The charging substances are directly reduced to sponge iron in a reduction zone (12) and the sponge iron is melted in a melt-down gasifying zone (8) under the supply of carbon carriers and oxygen-containing gas. CO-and H2-containing gas is introduced into the reduction zone (12) and is reacted there. An export gas is withdrawn and conducted to a consumer (20). The export gas is subjected to CO2 removal or partial combustion and the resulting gas with CO2 is introduced back into the reduction process. This is done to keep down the carbon carriers having high portion of Cfix as well as consumption of O2. A highly CO2-containing gas having a CO2 content far in excess of the CO2 content of the export gas, preferably exceeding 40%, and having a CO content that is far below the CO content of the export gas is introduced into the melt-down gasifying zone (8).
摘要翻译：在由含铁矿石，优选为块状或丸状物以及任选的助熔剂的填充物质生产液体生铁或液态钢预产品的方法中。充电物质在还原区（12）中直接还原成海绵铁，并且在碳载体和含氧气体的供应下，在熔融气化区（8）中将海绵铁熔化。将含CO和H 2的气体引入还原区（12）中并在其中反应。出口气体被撤回并传送给消费者（20）。出口气体经过二氧化碳去除或部分燃烧，所产生的带有二氧化碳的气体被引回还原过程。这样做是为了阻止具有高Cfix部分的碳载体以及O2的消耗。将CO 2含量远远超过出口气体的CO 2含量，优选超过40％，并且具有远低于出口气体的CO含量的CO含量的高含CO 2气体被引入熔体气化区（8）。
