Description
Technical Field
The utility model belongs to the technical field of industrial water treatment, and relates to a high-concentration fine particle rapid precipitation device.
Background
The steel can generate oxidation reaction with air in the hot forming process, a layer of iron scale is generated on the surface of the steel, and the iron scale can influence the next-stage rolling. In order to remove the oxide scale layer, the rolling process is usually treated by an acid washing or acid-washing-free mode, and the acid washing mode cannot avoid generating acid-containing wastewater and the influence of acid mist on the environment. In recent years, with the call for environmental protection, the pickling-free treatment process has attracted much attention. One suitable acid-washing-free treatment process is that mortar with certain pressure is thrown to the upper surface and the lower surface of a steel plate in an acid-washing-free treatment unit so as to achieve the purpose of removing iron oxide scales. The mortar used in the process flows into a steel sand pool at the lower part, wherein large-particle steel sand sinks into the steel sand pool, and water overflows to the next stage for treatment. The overflowed water slag contains a large amount of solid particles, the concentration of suspended matters is as high as more than 1200mg/L, and the water quality can not meet the requirement of circular production. The traditional circulating water treatment process is characterized in that an iron sheet ditch is built in a main plant and led out of the plant, and a plurality of communicated water treatment structures are built outside the plant for treatment, so that the treatment mode is more suitable for the process with large circulating water consumption.
