(1) energy-saving effect
Main energy consumption of the present utility model is blower motor, and the energy consumption of blower fan is relevant with the rotating speed of unit, and the air quantity Q of blower fan is directly proportional to rotating speed n, blast H is directly proportional to rotating speed n2, shaft power N is directly proportional to rotating speed n3, and when rotating speed n reduces, its actual power reduces in the ratio of rotating speed n3.Adopt the mode of motor variable-frequency speed-regulating, the rotating speed of blower fan changes with the change of flow system flow or pressure, and power savings is fairly obvious.After tested, frequency conversion fan runs under 43HZ, and after machine, pressure remains on 23KPa, and rotating speed declines 23%, and energy-conservation is 30%.Be 200 tons/hour for the FBN-200S(process water yield) type product: 1 Fans power of motor is for 15KW/ hour, 2 feeding spraying pump power are 7.4KW, annual running time calculated by 8000 hours, 1. after adopting motor variable-frequency speed-regulating, can save electricity be that 15KW/ overlaps × 8000 hours × 30%=3.6 ten thousand degree/cover every year, producing 600 covers per year can save electricity be 2,160 ten thousand degree, and electricity price, by 1.3 yuan of/hour calculating, can power cost saving be 2,808 ten thousand yuan every year; When 2. wherein having that temperature was on the low side in about 80 days an annual winter, the automatic start-up temperature control system of unit, can to stop using spray pump, can save electricity be × 80 days × 24 hours/day=1.42 ten thousand degree, 7.4KW/ cover/cover every year, producing 600 covers per year can save electricity be 8,520,000 degree, can power cost saving be 1107.6 ten thousand yuan every year.Above 2 totals and whole project can save electricity be 3,012 ten thousand degree every year, can power cost saving be 3915.6 ten thousand yuan.
(2) water-saving result
According to Liquid-Vapor Phase Transition principle, in cooling tower, use water as condensing agent, by condensing unit, condensing agent is injected into fine liquid particles equably, directly condensation is carried out to the thermogenetic steam of cooling procedure Evapotranspiration, make steam be transformed into condensate water, thus reduce evaporation loss, realize cooling tower water saving.Adopt high-efficient water-recovering device and automatic control condensing unit that 75%-90% steam of enclosed cooling unit shower water evaporated water can be made to change condensate water into.
It is 200 tons/hour with the FBN-200S(process water yield, spray pump flow is 100 tons/hour) type product is example: traditional open cooling tower recirculated water consumption per hour is 2%, vaporation-type enclosed cooling unit water consumption per hour is 0.8% × (1-80%)=0.16%, and water of saving per hour consumes 2% × 200 ton-0.16% × 100 tons=3.84 tons/cover.
600 water-saving amounts overlapping products annual reach: 600 cover × 8000 hours/annual × 3.84=1843.2 ten thousand tons.Amounting to RMB is: 1843.2 ten thousand tons × 2.5 yuan/ton=4,608 ten thousand yuan.
