Device for physically treating industrial circulating water

Abstract

The invention relates to a device for physically treating industrial circulating water. In the device, a water pipeline is sequentially provided with a water-supplementing electromagnetic valve, a media filter, an electronic descaling instrument, a conductivity real-time analyzer, a front pollution-discharging electromagnetic valve, a copper / silver ion generator and a back pollution-discharging electromagnetic valve, wherein a solenoid coil of the electronic descaling instrument is wound around the pipeline, a conductivity sensor is arranged in the pipeline, the media filter is in series connected to the pipeline, the copper / silver ion generator is in parallel connected to the pipeline, and the conductivity real-time analyzer is provided with output ends which are respectively connected with the water-supplementing electromagnetic valve, the front pollution-discharging electromagnetic valve, the back pollution-discharging electromagnetic valve, the copper / silver ion generator and the electronic descaling instrument. The device physically removes suspended solid impurities in the circulating cooling water, kills alga, bacteria and viruses in the water, prevents water from scaling on the device, eliminates the scale layer arranged on the device, detects the conductivity of water on line, discharges cooling water with higher cycles of concentration, supplements new cooling water, enables the cooling water to be under duty-cycle operation for a long time, has the advantages of simple operation and lower cost, and does not generate environmental pollution.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an industrial circulating cooling water treatment device. Background technique [0002] Industrial circulating water has open circulating cooling water. The circulating cooling water is used to cool and recycle the cooling water through the cooling tower, such as the circulating cooling water used by the steam turbine condenser in the thermal power plant. During the circulation of cooling water, the water quality of cooling water will have the following changes and effects: [0003] 1. Calcium and magnesium ions in the cooling water will precipitate, and the precipitated calcium and magnesium ions will scale on the surface of the heat exchanger; [0004] 2. During the cooling water circulation process, part of the water in the cooling water will evaporate, which will increase the content of soluble solids in the cooling water and concentrate the cooling water; [0005] 3. The cooling...

Problems solved by technology

[0006] 4. When the circulating cooling water is in an open environment, dust and debris will enter the cooling water, which will increase the suspended solid impurities in the cooling water

In order to prevent calcium and magnesium ions in the cooling water from scaling on the surface of the equipment and multiplying algae, bacteria and viruses in the cooling water, in the prior art, it is judged whether the quality of the cooling water exceeds the standard by experience or testing methods, and the circulating cooling water is added including There are chemical agents combined with scale inhibitors, corrosion inhibitors, biocides, surfactants, dispersants and defoamers. This kind of chemical treatment of industrial circulating cooling water is not only troublesome in operation and high in cost, but also will pollute the environment
