Abstract

The invention relates to the field of iron and steel smelting, and provides a turbid circulating water treatment system for direct reduction iron-making of a gas-based shaft furnace. The system comprises a cold turbid circulating water tank, a hot turbid circulating water tank, a central driving thickener, a cooling tower, a platform device, a sludge tank, a platform liquid collecting tank and a sludge liquid collecting tank, wherein the cold turbid circulating water tank and the central driving thickener are connected with a tap water pipeline network; the cold turbid circulating water tank supplies water to the platform device by virtue of a first water pump; the platform device is connected with the platform liquid collecting tank; the platform liquid collecting tank is connected with the central driving thickener by virtue of a second water pump; the central driving thickener is connected with the cold turbid circulating water tank and the hot turbid circulating water tank; the central driving thickener is connected with the sludge tank by virtue of a bottom valve; the sludge tank is connected with the sludge liquid collecting tank; the sludge liquid collecting tank is connected with the central driving thickener by virtue of a submerged pump; the hot turbid circulating water tank is connected with the cooling tower by virtue of a third water pump; and the cooling tower is connected with the cold turbid circulating water tank.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, and provides a turbid ring water treatment system for direct reduction ironmaking in a gas-based shaft furnace. technical background [0002] In the process of the rapid development of my country's national economy, the bottleneck effect of resources has become more and more prominent, especially with the rapid development of my country's industrial and agricultural production and the intensification of people's living activities, the demand for water and the discharge of sewage have increased sharply, resulting in water pollution. Resources are extremely tight and water pollution is becoming more and more serious. The iron and steel industry is one of the most important raw material industries and plays a pivotal role in the metallurgical industry, but the water consumption of the iron and steel industry accounts for as much as 20% of the total water consumption in the country. The turbid ...
