Description
Technical field
The utility model relates to a kind of circulatory system, relates in particular to a kind of cooling water recirculation system.
Background technology
Recirculated cooling water is the water sport in water for industrial use, and in industries such as petrochemical industry, electric power, iron and steel, metallurgy, the consumption of recirculated cooling water accounts for the 50-90% of enterprise water use total amount.Owing in former water, having different salt content, recirculated cooling water to be concentrated to certain multiple, must discharge certain dense water, and supplement new water.300,000 KW condensation units, the circulating cooling water yield to reach 3.3 ten thousand tons/time about, suppose that in former water, salt content is 1000mg/L, cycles of concentration is 3, the concentrated water discharge of recirculated cooling water is about 6-8 ‰ left and right, i.e. 198-264m so
3/ h, need the new water that supplements to equal draining and evaporation loss etc. simultaneously, and amount of makeup water is approximately 2-2.6% of quantity of circulating water, will be 660-860m
3/ h left and right, the quantity of water resources consumption and sewage discharge is very large.
Recirculated cooling water is by pumping toward each user in cooling system, and temperature raises after heat exchange, is sent to cooling tower and carries out cooling.Hot water sprays into water droplet or moisture film shape downwards from tower top in cooling tower, and air reverse or level interchange flows, and in the air water contact process, carries out heat exchange.Water temperature is down to while meeting the cooling water requirement, continues to recycle.
When air is overflowed by tower top, take away steam, make the increase of recirculated water ions content, therefore must supplement fresh water, discharge condensed water, to remain salt content at finite concentration, thereby the assurance whole system is normally moved.The amount of supplementing water should make up the water yield of system evaporation, wind (comprise and splashing and entrainment) and blowdown loss.The ratio of salt content in recirculated water and supplementing water, be the cycles of concentration of this circulation.In certain recirculating cooling water system, as long as change the salt content of supplementing water, just can change the cycles of concentration of circulation, and improve cycles of concentration, be the key that guarantees whole recirculating cooling water system economical operation.
Cooling water constantly recycles in the circulatory system, due to concentrating of water temperature rising, change in flow, evaporation, various inorganic ions and organic substance, cooling tower and cooling pond are subject to entering of solar radiation, wind and weather, dust foreign material outdoor, and the comprehensive function of the many factors such as structure and material of equipment, can produce a lot of problems.
1, incrustation scale adheres to
In recirculating cooling water system, the concentration of bicarbonate increases with evaporation and concentration.When its concentration reaches hypersaturated state, or while through the heating surface water temperature, raising, can decompose the Formed hydrochlorate and be deposited on heating surface, form fine and close microsolubility salt incrustation scale, its heat conductivility very poor (≤1.16W/ (m.K), steel are generally 45W/ (m.K)).Therefore, incrustation scale adheres to, and gently reduces heat exchanger heat transfer efficiency, when serious, heat exchanger is stopped up, and SR increases, and water pump and efficiency of cooling tower descend, and energy consumption increases, and production declining is accelerated local corrosion, even causes improper stopping production.
2, equipment corrosion
In recirculating cooling water system, large number quipments is by the metal manufacture, uses for a long time recirculated cooling water, can the corrosion perforation.This is caused by many factors, mainly contains: the electrochemical corrosion that cooling oxygen in water causes; Harmful ion (Cl
-And SO
4 2-) corrosion that causes; The corrosion that microorganism (anaerobic bacteria, iron bacteria) causes etc.Equipment wall erosion perforation, can form seepage, or processing medium is released in cooling water, loss material, polluted-water; Or cooling water infiltration processing medium, affect product quality, economic loss, impact safety in production.
3, microorganism grows and foundry loam
In recirculated water, due to concentrating of nutrient, water temperature raises and solar radiation, has created condition for the rapid breeding of bacterium and algae.The mucus of bacterium secretion is attached on together the dust impurity of water float and chemical precipitates etc., forms deposit and is attached to heating surface, be i.e. biological clay or soft dirt.Foundry loam adheres to can cause corrosion, and cooling water flow reduces, and then reduces cooling effectiveness; When serious, can block pipeline, forcing stops production cleans.
In sum, after cooling water recycles for a long time, will inevitably bring fouling, corrosion and microorganism algae to grow problem, make in recirculated water and have a large amount of solid waste, thus regularly discharging, contaminated environment not only, but also caused water resource waste.
Summary of the invention
For after solving cooling water and recycling for a long time, the recirculated water that discharging contains solid waste causes the problem of environmental pollution and water resource waste, and the utility model provides a kind of cooling water recirculation system that can substantially realize zero-emission.
The technical solution of the utility model is as follows:
