Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
With reference to Fig. 1, a kind of fouling of circulating-water in thermal power plant system, corrosive equipment of preventing of the present utility model, the water collecting basin 2 of water cooling tower 1 and its underpart is equipped with Scale inhibitors agitator tank 4 in water cooling tower one side, and it links to each other with the circulating water system pipeline by pipeline and a Scale inhibitors volume pump 13.In addition a sulfuric acid basin 3 and the coupled sulfuric acid volume pump 5 arranged side by side with above-mentioned Scale inhibitors adding set, the two links to each other with the circulating water system pipeline equally by the road.Be provided with filtration unit in the water collecting basin outlet, the water that is come out by filtration unit links to each other with recycle pump 6 by pipeline and valve six.The effluent pipe mouth of recycle pump 6 links to each other with the suction culvert of condenser 12 hydrophone 7 backs after filtration.On the inlet and outlet pipe of condenser 12, also be connected to glueballs divider 8, Rubber ball pump 9, ball collector 10 and ball screen 11.
In order to reduce suspension content in the whole water circulating system, at the water circulating pump suction culvert, the condenser inlet, filtration unit is installed at outlet position, water cooling tower pond respectively.
Shown in the accompanying drawing 2, install back-purge system additional in the water cooling system of motor air cooler, described back-purge system is but to connect a back flush valves 22 on system's outlet pipeline 23 in level, and this back flush valves connects service water water-in/pump.Connect a wash water valve 25 on air cooler water cooling system suction culvert, the sewage of back flushing is discharged through wash water valve.In order to reduce suspended substance in the air cooler water cooling system, a strainer 28 is set at inlet valve 29 rear portions.
System work process is as follows:
1, the prevention of fouling in water circulation system and on-line cleaning
Circulating water system employing corrosion inhibiting and descaling agent is auxiliary to add the sulfuric acid combined treatment process, and the Control Circulation total hardness of water is below 25mmoL/L.
The normal control about 8.3 ± 0.2 of recirculated water PH, it is poor to strengthen the heat-exchange equipment end in actual production, the statistical study work of economic targets such as the recirculated water import and export temperature difference.When judging that the heat-exchange equipment tube bank has fouling tendency, in sulphuric acid tank 3, quantitatively in system, add sulfuric acid through sulfuric acid volume pump 5, recirculated water PH is transferred to about 6.5 ~ 7, about operation 10 ~ 24h, the on-line cleaning of realization system (also can regularly reduce system's pH value operation in the actually operating, reach the purpose of pre-good antiscale property, general every month once, each run 6 ~ 8h).
Utilize the chance of shutting down maintenance, strengthen the visual inspection of condenser copper tube and take out pipe inspection work, adjust Scale inhibitors consumption and operation scheme according to the water quality situation.
2, the backwash operation of air cooler cooling water system
Height according to envrionment temperature is suitably adjusted unit load, and arranges the special messenger to monitor the changing conditions of generator import and export wind-warm syndrome between flush period at the scene, finds should in time stop backwash operation when wind-warm syndrome comparatively fast increases.
Slowly open back flushing control valve 21, behind the wash water valve 25, close air cooler water coolant outlet valve 24 and a water intaking valve 29 and a secondary water intaking valve 27 and begin flushing.
Flushing finishes, and opens air cooler water coolant import and export valve successively, checks and closes back flushing control valve and wash water valve tight.
