Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a steel plant circulating water deep purification and reuse device. Background Art

[0002] In the steel production process, the circulating water system plays a vital role. It not only reduces production costs but also reduces the impact on the environment.

[0003] Traditional methods for purifying circulating water in steel mills rely primarily on physical filtration and chemical treatment. Physical filtration traps suspended solids through the filter media layer, but struggles to remove dissolved pollutants. While chemical treatment can remove some dissolved pollutants, it typically requires the addition of large amounts of chemicals. This uneven distribution of chemicals can lead to localized deterioration of water quality, compromising purification effectiveness. Therefore, we propose a device for deep purification and reuse of circulating water in steel mills. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a steel plant circulating water deep purification and reuse device, which can solve the problem that although chemical treatment can remove some soluble pollutants, it usually requires adding a large amount of reagents to the water, and the uneven distribution of the reagents can easily lead to local water quality deterioration, affecting the purification effect.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a steel plant circulating water deep purification and reuse device, comprising:

[0006] Cold water tank, cooling tower, dosing tank, sewage pump and filter. The top of the cold water tank is fixed with a mounting plate;

[0007] The chemical spraying structure is located on the cold water pool;

The water inlet end of the water pump is connected to the interior of the cold water pool. The water outlet end of the water pump is fixedly connected to the reinforced pipe. The reinforced pipe is fixedly installed on the cold water pool. The end of the reinforced pipe away from the water pump extends into the interior of the cold water pool.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1.
