Device and a method for ion-induced regulation and control of industrial circulating water treatment

Abstract

The invention discloses a device and a method for ion-induced regulation and control of industrial circulating water treatment, and relates to the technical field of water treatment, a dosing system is connected with a medicament distributor at the lower part of an ion-induced regulation and control reactor through a pipeline, and a raw water tank is connected with a water distributor at the lowerpart of the ion-induced regulation and control reactor through a pipeline; a water outlet is formed in the upper part of the ion-induced regulation reactor, an exhaust port is formed in the top of the ion-induced regulation reactor and used for exhausting residual CO2 gas, and a crystallization outlet is formed in the bottom of the ion-induced regulation reactor. The method and device have the beneficial effects that metal ions in water are enriched to the surface of the catalyst through the ion-induced catalyst to generate water-insoluble precipitates which are attached to inner holes and the surface of the catalyst and continuously grow to form spherical particles to be discharged out of a system, so that the metal ions in the water are removed, circulating water is purified, the evaporation rate of the circulating water is improved, and scaling and corrosion damage of harmful ions in the water to a circulating system are reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an ion-induced regulation and control industrial circulating water treatment method and device. Background technique [0002] During the operation of large-scale metallurgy, petrochemical and chemical production, it is necessary to use a large amount of industrial circulating water to exchange the heat generated in the production process to ensure the normal operation of production. There is a certain amount of Ca in industrial circulating water 2+ , Mg 2+ , Fe 2+ , Mn 2+ 、As 3+ and F - Plasma, in the process of operation, will cause great scale, corrosion and other hazards to equipment pipelines. In order to prevent and reduce Ca in circulating water 2+ , Mg 2+ , Fe 2+ , Mn 2+ 、As 3+ and F - The harm caused by plasma to production equipment, the traditional method is to add a sufficient amount of anti-scaling agent and corrosion inhibitor in the circulating wa...

There is a certain amount of Ca in industrial circulating water 2+ , Mg 2+ , Fe 2+ , Mn 2+ 、As 3+ and F - Plasma, in the process of operation, will cause great scale, corrosion and other hazards to equipment pipelines. In order to prevent and reduce Ca in circulating water 2+ , Mg 2+ , Fe 2+ , Mn 2+ 、As 3+ and F - The harm caused by plasma to production equipment, the traditional method is to add a sufficient amount of anti-scaling agent and corrosion inhibitor in the circulating water. The disadvantages are that a large amount of chemicals need to be added, resulting in waste and increased operating costs. On the other hand, due to the evaporation loss of water during the operation of the circulating water, the Ca in the circulating water will 2+ , Mg 2+ , Fe 2+ , Mn 2+ 、As 3+ and F - Plasma is continuously enriched and the concentration is increased. It is necessary to discharge a large amount of concentrated salt wastewater and continuously replenish fresh water to ensure the normal operation of production, resulting in a great waste of water resources. At the same time, the discharge of concentrated salt water also puts pressure on the subsequent high-salt wastewater treatment.
