Description
Technical field
The utility model relates to water treatment facilities, and particularly a kind of industrial circulating cooling water is processed rear recycling device.
Background technology
Water for industrial use mainly comprises boiler feed water, process water, water for cleaning and cooling water, sewage etc.Wherein water consumption maximum is cooling water, accounts for the more than 90 percent of industrial water consumption.Different industrial systems and different purposes are different to the requirement of water quality; But the cooling water that each industrial department uses is consistent to the requirement of water quality substantially, this just makes quality of cooling water be controlled in recent years and has obtained development rapidly as an application technology.In factory, cooling water is mainly used to condensed steam, and cooling products or equipment, if cooling effect is poor, will affect production efficiency, make the yield of product and the Quality Down of product, can cause production accident even.Therefore need to make corresponding processing to recirculated cooling water, to recover the conductivity of heat that recirculated cooling water is good.
Water is more satisfactory cooling medium.Because the existence of water is very general, to compare with other liquid, thermal capacitance or the specific heat of water are larger, and the latent heat of vaporization of water (evaporation latent heat) and the latent heat of fusion are also very high.Specific heat is the heat that the coolant-temperature gage of unit mass absorbs while once raising.Conventional unit is card/gram degree (Celsius) or British thermal unit (B.T.U.)/pound degree (Fahrenheit).While spending with these two unit representation specific heat of waters, its numerical value is identical.During thermal capacitance is large or specific heat is large material rising temperature, need to absorb a large amount of heats, and self-temperature not obvious rising, so glassware for drinking water has good heat retention characteristic.When latent heat is states of matter generation transformation, institute absorbs or liberated heat.1g molecular water evaporation becomes the heats that 1g molecular vapors need to absorb nearly 10,000 cards, so can absorb a large amount of heats during water evaporation, thereby makes water temperature decline, and the process that this dependence moisture evaporator strip is walked heat is called evaporative heat loss.
The same with water, air is also a kind of conventional cooling medium.The heat conductivility of water and air is all very poor, and in the time of 0 ℃, the thermal conductivity factor of water is 0.49 kilocalorie/meters per hour ℃, and the thermal conductivity factor of air is 0.021 kilocalorie/meters per hour ℃, but water compares with air, and the thermal conductivity factor of water is than the high 24 times of left and right of air.Therefore,, when cooling effect is identical, the air-cooled equipment of water cooling raio is much smaller.The factory that large size industrial enterprise and water consumption are large generally all adopts water cooling.Conventional water-cooling system can be divided into three classes, i.e. straight-flow system, closed system and unlimited vapo(u)rization system, and latter two cooling water all recycles, therefore be called again recirculating cooling water system.
Unlimited vapo(u)rization system is the maximum a kind of cooling system of most widely used, type at present.It is also to remove with water cooling the heat that processing medium or heat transmission equipment are distributed, while then utilizing hot water and air directly to contact, a part of hot water is evaporated away, and make most of hot water obtain cooling after, recirculation is used.Therefore, such system also claims to open wide recirculating cooling water system.How increasing the cooling effect of Open recirling cooling water system, is the problem receiving much concern at present.
