Accompanying drawing explanation
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, wherein:
Fig. 1 illustrates the structure iron of the Water Treatment in Circulating Cooling System of the utility model one embodiment.
Embodiment
Fig. 1 illustrates the structure iron of the Water Treatment in Circulating Cooling System of the utility model one embodiment.Shown in figure 1, a typical recirculating cooling water system 10 comprises cooling tower 11, heat exchanging apparatus 12 and water circulating pump 13, and three forms a closed circulation.
The present embodiment uses the Water Treatment in Circulating Cooling System 20 of By Ozone to carry out cycle for the treatment of water coolant, plays the effect of scale inhibitor sterilization.Water Treatment in Circulating Cooling System 20 comprises ozonizer 21, pressure air-dissolving tank 22, mixing wastewater with air element 23, microvesicle generating device 24, first outlet valve 25 and the second outlet valve 26.The water-in of mixing wastewater with air element 23 connects the molten gas intake 14 on recirculating cooling water system 10 by pipeline, the inlet mouth of mixing wastewater with air element 23 connects ozonizer 21 by pipeline.It is inner that microvesicle generating device 24 is located at pressure air-dissolving tank 22, and it connects the water outlet of mixing wastewater with air element 23.Pressure air-dissolving tank 22 has the first water outlet 22a and the second water outlet 22b.First water outlet 22a connects the ozone water inlet 15 on recirculating cooling water system 10 by pipeline.At this, ozone water inlet 15 is between the cooling tower 11 and water circulating pump 13 of recirculating cooling water system 10.First outlet valve 25 is located between the first water outlet 22a and ozone water inlet 15.Second water outlet 22b is connected in the water accumulating disc 11a of the cooling tower 11 on recirculating cooling water system by pipeline.Second outlet valve 26 is located between the second water outlet 22b and ozone air-water water distributor 17.The position of the first water outlet 22a is lower than the second water outlet 22b.The sidewall of the pressure air-dissolving tank 22 that such as the first water outlet 22a is positioned at, the second water outlet 22b is positioned at the top of pressure air-dissolving tank 22.
During work, the water of recirculating cooling water system enters the water-in of mixing wastewater with air element 23 through molten gas intake 14, the ozone gas simultaneously produced by ozonizer 21, enter the inlet mouth of mixing wastewater with air element 23, ozone gas and water enter microvesicle generating device 24, under the effect of high-speed rotary shear force, air pocket is cut into microvesicle, and fully mix with water, form the air-water mixture of high density, discharge in pressure air-dissolving tank 22.
Contain in the air-water mixture of microvesicle what discharge, bubble-free dissolved ozone water can by the first water outlet 22a being in low level, through the first outlet valve 25, be injected into ozone water inlet 15, after mixing with the water in pipeline before water circulating pump 13, input heat exchanging apparatus 12 through water circulating pump 13, the process of inhibition descaling, and blocking scaling is carried out to heat exchanging apparatus 12.The low level of the first water outlet 22a can make the liquid of outflow be the dissolved ozone water having removed bubble as much as possible, therefore avoids the harm of cavitation erosion to water circulating pump 13.In addition, the tail gas such as the oxygen after undissolved ozone gas Sum decomposition can be assembled at the top of pressure air-dissolving tank 22, through the second water outlet 22b by the second outlet valve 16 control discharge, during discharge, the release with no pressure in the water accumulating disc 11a being arranged on cooling tower 11 of tail gas mixing portion dissolved ozone water, makes full use of tail gas and carries out sterilization algae removal to cooling tower 11.
Ozone air-water water distributor 11b can be arranged in the water accumulating disc 11a of cooling tower 11, make the second water outlet 22b be connected to ozone air-water water distributor 11b, complete tail gas release.
Preferably, take out that the water yield is piping flow after water circulating pump 3 from molten gas intake 14 5% is controlled.At this, water intaking valve 27 can be arranged between molten gas intake 14 and the water-in of air water hybrid element 23, thus control flow.
Topping-up pump 28 can be arranged before mixing wastewater with air element 23, be used for ozone gas supercharging.
Pressure air-dissolving tank 22 can adopt stainless steel, prevents the corrosion of high-concentrated ozone.Pressure air-dissolving tank 22 aspect ratio can be arranged on the scope of 1.5-3.The pressure of more than 0.1MPa is kept, the residence time 15-30 second of water in pressure air-dissolving tank 22.
In order to guarantee that the liquid of outflow first water outlet 22a is the dissolved ozone water having removed bubble further, in the middle of pressure air-dissolving tank 22, a dividing plate 22c is set, the bottom space of pressure air-dissolving tank 22 to be divided into first area, second area two regions.Microvesicle generating device 24 is arranged on the first area bottom dissolving, and the first water outlet 22a is arranged on the second area bottom dissolving.The height that can arrange dividing plate 22c is about the half of the diameter of pressure air-dissolving tank 22, enough to stop bubble.
Rely on the control to the first outlet valve 25, second outlet valve 26, the Water Treatment in Circulating Cooling System of the present embodiment can work in different modes.For example, in a first mode, recirculating cooling water system 10 24 littlely often to open, and so the first outlet valve 25 of Water Treatment in Circulating Cooling System 20 also keeps often opening, and is only injected into the position of ozone water inlet 15.When the undissolved gas of pressure air-dissolving tank 22 acquires a certain degree, when needing release, just periodically open the second outlet valve 26, by ozone gas and a small amount of ozone water, be injected into ozone air-water water distributor 11b, carry out waste gas utilization.That is, in the flrst mode, the first outlet valve 25 is configured to be held open, and the second outlet valve 26 is configured to time opening.For example, the open frequency of the second outlet valve 26 is set to every 4 hours once, each 15 minutes.Open frequency and each opening time of the second outlet valve 26 are all configurable.
According to different operating modes in engineering, Water Treatment in Circulating Cooling System 20 can be allowed to run under other pattern.Such as local at some, as subway station, night, heat exchanging apparatus 12 was do not run or underrun, without the risk of fouling, can close the first outlet valve 25 like this at night, whole ozone water is by the second outlet valve 26, enter cooling tower 11, carry out sterilizing and algae-removing.Also under some extreme case, heat exchanging apparatus 12 runs always, but when algae increases fast in cooling tower 11, also can close the first outlet valve 25 short period of time, makes ozone water all enter the second outlet valve 26, concentrates algae removal.That is, under one second pattern, the first outlet valve 25 is configured to close, and the second outlet valve 26 is configured to open.The working time of the second pattern can be determined as required.
Above-mentioned employing ozone ultra micro rill technology of the present utility model carries out the process of recirculated cooling water, takes into account the treatment effect of recirculated cooling water scale inhibitor sterilization simultaneously.Through overtesting, adopt said system, substantially effectively utilizing of ozonizer generates ozone can be realized, water quality is limpid, and on heat exchanging apparatus, Non-scale and corrosion thing, present metalluster, total plate count is less than 1000cfu/ml, and without legionella, biological sludge in industrial is less than 2ml/m
