Industrial circulating cooling water system

Abstract

The invention relates to the technical field of water treating equipment, in particular to an industrial circulating cooling water system. The technical scheme is as follows: the industrial circulating cooling water system comprises a cooling tower, a water supply line leading to a water consuming point, a filtered water circulating line connecting the water consuming point and the cooling tower and a raw water supply line supplementing water to the cooling tower, wherein the water supply line is connected with a water outlet of the cooling tower and comprises and a start-stop control valve which is used for controlling connection and disconnection of the water supply line and is connected in the line in series; the filtered water circulating line comprises a throttle valve, a bypass filter device, a water circulating line shutoff valve, a bamboo charcoal filter tank, a sludge sedimentation tank, a line shutoff control valve group and a filter which are connected sequentially in the water flow direction, and bamboo charcoal filter tank takes bamboo charcoal as a filter material. The industrial circulating cooling water system has the advantages of good water purification treatment effect, energy saving, environmental protection, safe, stable and lasting operation and convenience in maintenance.

Description

technical field [0001] The invention relates to the technical field of industrial water treatment equipment, in particular to an industrial circulating cooling water system. Background technique [0002] At present, there are common problems in the daily operation of industrial circulating cooling water, such as corrosion of pipes and heat exchange equipment, and gradual deterioration of heat exchange effect. The main reasons are: [0003] 1. The scale circulating cooling water evaporates continuously during the cooling process, so that the salinity concentration in the water increases continuously, exceeding the solubility of some salts and depositing. The common ones are calcium carbonate, calcium phosphate, magnesium silicate and other scales. The dense texture of scale can prevent corrosion of metal surfaces, but it greatly reduces heat transfer efficiency. [0004] 2. Dirt is mainly composed of organic matter in water, microbial colonies and secretions, dust and othe...

AI Technical Summary

Problems solved by technology

It is easy to breed harmful components such as hydrogen sulfide, and the texture of the scale is soft, which not only reduces the heat transfer efficiency but also causes corrosion under the scale

[0005] 3. The cause of dirt generated by sufficient oxygen in water, corrosion ions Cl-, Fe2+, Cu2+ in water and mucus secreted by microorganisms, the consequences of corrosion are quite serious

[0006] 4. Sufficient oxygen, suitable temperature, and rich nutrients in circulating water are more suitable for the growth and reproduction of microorganisms. If not controlled in time, it will lead to deterioration of water quality, odor, a large amount of slime scale deposition, and equipment corrosion will increase.

As a result, the cost of raw water production has risen, and serious waste of water resources cannot be done accordingly.
