Embodiment

[0027] The present invention is a reclaimed water reuse process for cooling systems in the metal industry, specifically passing the cooling water through a cooling tower 1, a bag filter 2, a manganese sand filter 3, a mixed bed 4, and a chelating resin bed 5 , step by step to remove the iron ions, calcium ions, and magnesium ions in the cooling water, and also filter out the suspended solids and particulate matter in the cooling water, so as to obtain the cooling water that meets the reuse standard.

[0028] Since the cooling water in the production area of ​​the metal industry passes through the production area and takes away the heat of the equipment and metal products, its own temperature is relatively high. The principle of water heat exchange, the heat in the cooling water is taken away through the air to realize the condition of cooling water for reuse. A cooling pool 6 can be set under the cooling tower 1, which can better hold the cooling water after cooling treatment ...

Abstract

The invention relates to a reclaimed water recycling technology used for a metal industrial cooling system. Raw water of the technology is cooling water containing various metal ions and impurities; the raw water passes through a cooling tower, a bag type filter, a manganese sand filter, a mixing bed and a chelating resin bed in sequence, and iron ions, calcium ions and magnesium ions in the cooling water are removed step by step; meanwhile, suspended matters and particulate matters in the cooling water also can be filtered, so that the cooling water reaching recycling standards is obtained; after a lot of metal ions in the cooling water are removed, the cooling water cannot react with a metal generation raw battery in a utilization process, so that damages to equipment and metal productsare reduced, the service life of the equipment is prolonged, and the quality of the metal products is improved; meanwhile, the effects of recycling water resources and reducing the cost are also realized, and certain guarantees are also provided for environment protection.

Description

technical field [0001] The invention relates to the field of reclaimed water reuse, in particular to the reclaimed water recycle field of cooling systems in the metal industry. Background technique [0002] With the continuous development of society, people's understanding of the metal industry continues to deepen, and at the same time, their dependence on the metal industry is becoming stronger and stronger. The development of the metal industry has repeatedly improved human living standards. [0003] The metal industry involves many categories and is also relatively complicated. It can be roughly divided into ferrous metal industry, non-ferrous metal industry and rare metal industry. In the field of metal industry, most of the processes involved require high-temperature and high-heat treatment. After the treatment, a corresponding cooling system is required to cool down the equipment and products. Since water has a good specific heat capacity, it can achieve a good cost pe...
