Description
Technical Field
The invention relates to the technical field of steelmaking auxiliary equipment, in particular to a steelmaking waste hot water circulating treatment device.
Background
In steel-making and related casting production enterprises, cooling water is used by a plurality of devices for cooling related products, but the water body of the cooling water has higher temperature after the cooling water is used up, and the manufacturers either directly discharge the cooling water out of the factory or store the cooling water by using a reservoir for recycling, but generally spend a longer time waiting for the waste heat water to be cooled for reuse when recycling; meanwhile, the use environment of the cooling water in the actual production environment of a factory is severe, a lot of sundries and oil stains are easily mixed in the cooling water in the use and operation process, and the obvious cooling effect is greatly reduced if the cooling water is directly reused.
Disclosure of Invention
The invention aims to provide a steelmaking waste hot water recycling device with simple structural design and good use effect, aiming at the problems of recycling the existing factory waste hot water.
The specific scheme of the invention is as follows: a steelmaking waste hot water circulation treatment device is provided with a first wastewater tank and a second wastewater tank which are arranged closely, wherein the height of the first wastewater tank is higher than that of the second wastewater tank, a truncated cone-shaped wastewater filtering structure is arranged on the first wastewater tank through a cross beam, a cavity is arranged in the wastewater filtering structure, two layers of filtering screens are arranged in the cavity from top to bottom, the aperture of the upper layer of filtering screen is larger than that of the lower layer of filtering screen, the lower layer of filtering screen is directly communicated with the first wastewater tank, and the top of the cavity is communicated with a waste hot water inlet pipe; a water distribution pipe is further arranged on the top edge of the first wastewater tank close to the second wastewater tank, a plurality of water mist spray nozzles are distributed on the water distribution pipe, all the water mist spray nozzles are distributed towards the second wastewater tank, one end of the water distribution pipe is closed, and the other end of the water distribution pipe is connected with a water pump a arranged at the bottom of the first wastewater tank through a hose; and a water inlet pipe at one end of the water pump b is communicated with the bottom of the second wastewater pool, and a water outlet pipe at the other end of the water pump b is communicated with the top of the first wastewater pool.
The waste water treatment device is also provided with a water pump c, a water inlet pipe of the water pump c is communicated with the bottom of the second waste water tank, and a water outlet pipe of the water pump c is communicated with external water using equipment.
The operation process of the device comprises the following steps: cooling water in a steel-making system is connected into a cavity of a waste water filtering structure through a waste hot water inlet pipe, impurities in the waste hot water can be basically filtered through two layers of filtering screens, and meanwhile, mixed oil stains can be adhered to the filtering screens due to the blocking effect of the filtering screens; filtered waste hot water enters the first wastewater tank, then the waste hot water is pumped into the water distribution pipe through the water pump a, and is sprayed into the second wastewater tank through the water mist spraying nozzle on the water distribution pipe, so that the waste hot water in the first wastewater tank can be rapidly and naturally cooled (due to the fact that the water mist is sprayed, the waste hot water is rapidly and naturally cooled in large-area contact with air), meanwhile, the water pump b pumps the waste water in the second wastewater tank into the first wastewater tank again, and the waste hot water is sprayed downwards again, so that circulation is realized, the original waste hot water can be rapidly cooled and cooled, and the waste hot water can be pumped into the steel-making system through the water pump c for cooling water again.
The device provided by the invention can rapidly recycle the original waste hot water after filtering and cooling the waste hot water discharged by the steelmaking system, and has good practical use and economic value.
