Steelmaking waste hot water circulation treatment device

Abstract

The invention relates to a steelmaking waste hot water circulation treatment device, which is provided with a first wastewater pool and a second wastewater pool which are arranged adjacently, whereina cone-frustum-shaped wastewater filtering structure is erected on the first wastewater pool through a cross beam, two layers of filtering screens are installed in a cavity from top to bottom, the filtering screen on the lower layer is directly communicated with the first wastewater pool, a water distribution pipe is further arranged on the first wastewater pool and close to the edge of the top ofthe second wastewater pool, a plurality of water mist spray nozzles are distributed on the water distribution pipe, one end of the water distribution pipe is closed, the other end of the water distribution pipe is connected with a water pump a arranged at the bottom of the first wastewater pool through a hose, a water pump b is arranged, a water inlet pipe at one end of the water pump b is communicated to the bottom of the second wastewater pool, and a water outlet pipe at the other end of the water pump b is communicated to the top of the first wastewater pool. According to the device, the waste hot water discharged from the steelmaking system is filtered and cooled, the original waste hot water can be quickly recycled, and the device has good actual use and economic value.

Description

Technical field [0001] The invention relates to the technical field of steelmaking auxiliary equipment, in particular to a steelmaking waste hot water circulating treatment device. Background technique [0002] In steelmaking and related foundry production enterprises, many equipment will use cooling water to cool related products, but the water itself has a higher temperature after the cooling water is used up, and the manufacturer either directly discharges it outside the factory or uses The reservoir is stored for reuse, but when it is reused, it usually takes a long time to wait for the waste hot water to cool before it can be used again; at the same time, the cooling water is used in the actual production environment of the factory because the environment is relatively harsh. A lot of debris and oil stains are easily mixed in the cooling water during operation, and the cooling effect will be greatly reduced if it is used directly again. Summary of the invention [0003] The ...

Problems solved by technology

[0002] In steelmaking and related foundry production enterprises, many equipments use cooling water to cool related products, but the water body itself has a relatively high temperature after the cooling water is used up, and the manufacturer either directly discharges it out of the factory, or uses The storage tank is stored for reuse, but it usually takes a long time to wait for the waste hot water to cool before it can be used again; at the same time, the cooling water is used in a harsh environment in the actual production environment of the factory. During the operation, a lot of sundries and oil stains are easily mixed in the cooling water. If it is directly used again, it is obvious that the cooling effect will be greatly reduced.
