Gate valve 1, tensimeter 2, thermometer 3, two y-type filters that are installed in parallel 5, magnetic flow meter 7, ultra-fine filter 8 are installed on water-main 31 successively.The installation of gate valve 1 is in order to regulate the flow of nozzle 28.The installation of tensimeter 2 is whether the hydraulic pressure in order to observe in water-main 31 is normal.In order to guarantee atomizing effect, in anti-sealing, impurity is blocked nozzle 28, on water-main 31, filtration unit has been installed, and filtration unit is two y-type filters that are installed in parallel 5 and ultra-fine filter 8, and two sides of y-type filter 5 are respectively provided with a manual valve 4.In order to measure the flow of water in water pipe, in this programme, also adopted flow detector, in the present embodiment, flow detector is magnetic flow meter 7, two sides of magnetic flow meter 7 are respectively arranged with manual valve 6, on the manual valve 6 of magnetic flow meter 7 and two sides, be also parallel with bypass, in bypass, be provided with manual valve 6, flow measurement device also can adopt other known under meters certainly.
Manual valve 6, automatic switch valve 9, magnetic flow meter 10, high pressure plunger pump 11, tensimeter 12, collector 22 are installed on water pipe branch road 25 successively.Manual valve 6 on water pipe branch road 25 is connected with the ultra-fine filter 8 on water-main 31.In order to obtain good atomizing effect, need larger pressure, therefore adopted high pressure plunger pump 11, the working pressure of high pressure plunger pump 11 is greater than 5MPa (MPa).Working pressure table 12 is in order to determine whether hydraulic pressure meets the requirements prescribed.Use the object of automatic switch valve 9 to be: by automatic switch valve 9 and electrical control gear are linked together, thereby to control easily the Kai Heguan of water in water pipe branch road 25.
On a kind of agglomerate atomized water refrigerating unit, a kind of blow device that is applied to nozzle is also installed.A kind of blow device that is applied to nozzle comprises tracheae 26, four tracheae branch roads 27 in parallel.Tracheae branch road 27 one end are connected with tracheae 26; The other end is connected with water pipe branch road 25, and tie point is between high pressure plunger pump 11 and tensimeter 12.
Specific embodiment is as follows: thermal sintering ore bed on stone grate plate 40 needs when cooling, to open three gas blowers above, and tap water enters water-main 31, and whether the pressure and temperature of observing water by tensimeter 2 and thermometer 3 meets the requirements prescribed; Water filters through y-type filter 5 and ultra-fine filter 8, removes physical pollutant, during through magnetic flow meter 7, record flow, guarantee that discharge meets the requirements prescribed; After ultra-fine filter 8 ultrafiltration, four water pipe branch roads 25 of flow direction, open manual valve 6 and the automatic switch valve 9 of water pipe branch road 25, current enter high pressure plunger pump 11 by magnetic flow meter 10, by high pressure plunger pump 11, hydraulic pressure is brought up to 5MPa-20MPa, current are through tensimeter 12 and enter nozzle 28 by collector 22, by tensimeter 12, can check whether pressure meets the requirements prescribed; Wherein magnetic flow meter 10 records the discharge in water pipe branch road 25, and atomized water, from nozzle 28 ejections, produces the uniform atomized water of spatial distribution.The atomization water yield that regulates nozzle 28 to spray by the gate valve 1 regulating on water-main 31, can certainly be by regulating other valve on water pipe 31,25 carry out regulating pondage.In order to reach good cooling performance, the nozzle 28 ejection atomization water yields must be greater than 20g/m
3(gram/cubic metre), in every cubic metres of air, the content of water is greater than 20g, is generally 20-150g/m
3.Owing to requiring atomizing effect better in this programme, the spray orifice aperture of nozzle 28 is 0.05-0.3mm, and spray orifice aperture can be 0.1mm and bis-kinds of specifications of 0.15mm.The swiftly flowing airflow mixing that atomized water and gas blower blow out penetrates the thermal sintering layer on stone grate plate 40, and water becomes water vapour, takes away the heat of heat sinter, and its temperature is reduced, and realization is cooling to heat sinter.Water vapour is together discharged from chimney 30 with airflow.
When using atomized water refrigerating unit, high-pressure pneumatic switch valve 17 cuts out.When not using atomized water refrigerating unit, for preventing that spraying plant 19 from stopping up, close the automatic switch valve 9 on water pipe branch road 25, open the valve in gas circuit, start blow device.Source purge gas can be used air or nitrogen; air-flow is by the gate valve 13 on tracheae 26; through source of the gas strainer 14, remove after dust impurity; air-flow enters respectively four tracheae branch roads 27; through manual ball valve 15, high pressure check valve 16, high-pressure pneumatic switch valve 17, high pressure hand-operated ball valve 18 on tracheae branch road 27, enter water pipe branch road 25 successively; finally enter atomized water system branch; through tensimeter 12, arrive nozzle 28 places of spraying plant 19; form gas passage; nozzle 28 is formed to protection, stoped dust to enter nozzle 28.The high velocity air that the gas of nozzle 28 ejections produces with gas blower is together discharged from chimney 30.Due to the spray orifice aperture of nozzle 28 be in the present embodiment 0.1mm or or 0.15mm, do not have in the spray orifice that large dust enters nozzle 28, the pressure of source purge gas does not need too large, relatively saves.Also can be to use blow device before using atomized water refrigerating unit, the dust in nozzle 28 spray orifices is blown away.If the spray orifice of nozzle 28 is pushed down by larger dust, also can use larger air pressure that dust is blown open.
