Embodiment
With reference to the accompanying drawings and examples, the present invention will be described in detail.
A kind of ecological circulation water-cooling system, as shown in figure 1, including multiple water storage units 2 being sequentially connected in series by valve, store Water unit 2 forms water storage module 1, and the quantity of water storage unit 2 is odd number, it is preferable that water storage unit 2 is 5, and valve is slide valve 3.The top of the side wall of water storage unit 2 is integrally disposed upon positioned at the slide valve 3 of head end, and other slide valves 3 are along the side of series connection of water storage unit 2 To both sides be staggered.
The top of the water storage unit 2 of head end is provided with water inlet module 4, water inlet module 4 includes parallel with one another and identical First spray module 5 with it is standby spray module 6, first spray module 5 with it is standby spray module 6 is separately positioned on water storage unit 2 along its connect direction both sides.As shown in Figure 2 and Figure 3, the first spray module 5 includes multiple water inlet pipes 7 in parallel, water inlet pipe 7 Surface offer multiple equally distributed apopores 8.Vertical branch is wholely set positioned at the side of the water storage unit 2 of head end Frame, water inlet pipe 7 is bolted on support and level is horizontal in the top of water storage unit 2.Apopore 8 is distributed in water inlet pipe On 7 other sides in addition to the one side away from water storage unit 2, and it is uniformly distributed along the length direction of water inlet pipe 7.Work as water temperature , it is necessary to which standby spray module 6 assists the first spray module 5 to be radiated during higher than design temperature, increase dissipating for hot water and air Hot area, improve radiating efficiency.Apopore 8 can be from the water in the both sides of water inlet pipe 7 and lower end water outlet, different apopores 8 Stream is not interfere with each other, if the upper end of water inlet pipe 7 also can water outlet, upper end outflow current can offset its spray under gravity Kinetic energy when going out apopore 8 and fall, the current of whereabouts can then interfere with other apopores 8 on water inlet pipe 7, it is not sprayed Current are projected, the contact area between current and air can not be increased, then reduce the radiating efficiency of current.
The removal of impurities module 9 for removing the impurity in the water storage unit 2 is provided with water storage unit 2.Cooling water is storing Cooled down in water unit 2 and produce algae impurity, these algae impurity enter in the circulatory system can blocking pipeline and damage equipment. Fish of the module 9 that cleans for cultivation in the water storage unit 2, fish can eat up these algae impurity so as to reach in water storage unit 2 To the effect of removal of impurities, without toward water treatment agent is added in water storage unit 2, increasing aesthetic measure again.Meanwhile fish is in water storage unit 2 In move about, the liquidity and heat exchange degree of the regional area reclaimed water of increase water storage unit 2, destroy what is occurred in water storage unit 2 It is unfavorable for the local circulation vortex of radiating, improves radiating effect
The pumping module 10 to extracardiac pumping is communicated with by slide valve 3 positioned at the side wall upper part of the water storage unit 2 of tail end.Draw water mould Block 10 includes multiple water pumps 11 in parallel, and the valve close to pumping module 10 is fixedly connected with filter screen 12.Water pump 11 in parallel with Series connection improves its draw water efficiency and power compared to having big load, and filter screen 12 can then prevent debris in water storage unit 2 and Fish is entered in pumping module 10.Water is entered from water inlet pipe 7 in the water storage unit 2 connected by slide valve 3, and current are being gone here and there Baffling is carried out in the water storage unit 2 of connection, is finally extracted out from outlet pipe 7 by pumping module 10.The flow path of current is maximized, is carried Gao Shui cooling effectiveness.
As shown in Fig. 2 being arranged in series heat exchange module 13 between water storage module 1 and pumping module 10, heat exchange module 13 wraps Heat exchange unit 14 and emptying unit 15 are included, heat exchange unit 14 is fixed by pipeline with pumping module 10 and connected, and emptying unit 15 is solid Connect calmly between heat exchange unit 14 and water inlet module 4, for discharging the vapor in water.Heat exchange unit 14 exchanges heat for spiral plate Device, spiral heat exchanger have the advantages of small volume, facility compact, heat transfer efficiency are high, metal consumption is few, applicable liquid and liquid Convection heat transfer' heat-transfer by convection between body, and produced without incrustation scale.Being vented unit 15 includes hot water storgae 16 and vent chamber 17, and hot water storgae 16 is connected Between heat exchange unit 14 and water inlet module 4, vent chamber 17 is fixed with hot water storgae 16 and connected.Hot water, heat are flowed into hot water storgae 16 The vapor of water is expelled directly out from vent chamber 17, and the hot water after being then vented enters water storage unit 2 by water inlet module 4.Heat exchange The height of unit 14 is higher than water storage unit 2, and the height of emptying unit 15 is higher than heat exchange unit 14, and heat exchange unit 14 is higher than water storage list The height of member 2 is 6m.Water in heat exchange unit 14 enters water storage unit 2 by water inlet module 4, without adding in water inlet module 4 Drive device is filled, the spray of water can be only completed with gravity, 6m height is beneficial to the construction of heat exchange unit 14, while has foot again Enough gravitional force.
When ecological circulation water-cooling system works, water is sprayed into water storage unit 2, current from water inlet pipe 7 by apopore 8 Divided by apopore 8 for the very thin current of multiply, and exchanged heat in atmosphere, add the area of dissipation of water, improve radiating Efficiency, and current carry out baffling in the water storage unit 2 of series connection, maximize the flow path of current, improve the cooling effectiveness of water. Fish in water storage unit 2 had both eliminated the algae impurity in water, was not in the situation of fouling in system, without using scale removal Agent, reduce production cost, while fish can also eat up biological impurities, hard water is changed into soft water, will not corruption, avoid line clogging with And prevent equipment from producing failure, moreover it is possible to increase the liquidity of the reclaimed water of water storage unit 2, and the part destroyed in water storage unit 2 is certainly Circulation vortex.It can make water that there is long flow path and radiation processes using 5 water storage units 2, while provide foot to fish again Enough activity spaces, when needing to clear up the mud in water storage unit 2, closing slide valve 3 disconnects adjacent water storage unit 2, Open slide valve 3 after the completion of for clearance again, whole cooling procedure goes to carry out heat exchange without the extra energy, energy-conserving and environment-protective, together Shi Shuiliu has big heat exchange area with air, and current have the flowing road of broken line type in the water storage unit 2 being staggered Footpath, there is high radiating efficiency.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications It should be regarded as protection scope of the present invention.
