By the utility model that above technical scheme constituted, its operation principle is following:
In the heat exchanger tube of the utility model vaporation-type heat-exchanger rig is closed circulating water system, and heat exchanger tube is outside for spraying shower water, and the shower water quantity of circulating water is about 1/4 of the closed circulating water system water yield.Shower water can circulate cooling and need not set up and independently spray the pond at vaporation-type heat-exchanger rig equipment itself, therefore takes up an area of for a short time, has saved investment and operating cost.
After equipment injected shower water, shower water was from the intrinsic spray equipment ejection of cooler, from heat exchanger tube outer flow mistake; Reduce the water temperature of the inner recirculated water of heat exchanger tube; Shower water continues to drop in the process of water-collecting tray, through air inlet, contacts with the air of the lower temperature that from cooling blower, blows out; The temperature of shower water decreases; After water-collecting tray was collected shower water, water pump was extracted the shower water of water-collecting tray out, and the spray equipment place that delivers to the vaporation-type heat-exchanger rig through the spray header pressurization proceeds spray.
And the frequency conversion scale inhibition appearance of the utility model can produce the signal of telecommunication of a variation; Act on the spray header through coil; Coil-induced generating an electromagnetic field makes that the shower water hydrone in the spray header produces judder, becomes single polar water molecules to the water clusters of hydrogen bond association; These atomic little hydrones can permeate, dissolve the zwitterion that is easy to generate incrustation scale, like Ca
2+, Mg
2+, CO
3 2, make it to form soft aragonite crystal, thereby stop its outside wall surface that is attached to spray header tube wall, spray equipment and heat exchanger tube, reached the purpose of scale inhibition.
Through operation test after a while; For conventional water quality (not comprising abominable water quality such as extreme hardness water); The operating frequency of the frequency conversion scale inhibition appearance of the utility model more should remain in the scope of 1kHz～18kHz; Under this frequency state, this frequency conversion antiscaling device is best to the scale inhibition effect of zwitterion.
The above act is merely the schematic part embodiment of the utility model; It is not scope in order to restriction the utility model; Any those skilled in the art; Equivalent variations of under the prerequisite of design that does not break away from the utility model and principle, having done and modification all should be included within this patent protection domain.
