Door and related thermal technology's measuring point etc..
The major function of thermal power plant's industry cooling water system provided in an embodiment of the present invention is mentioned to the Important Auxiliary equipment of thermal power plant
For continuously, the cooling water of high-quality, take away the heat generated during subsidiary engine equipment operation, and as recirculated water tower basin
Moisturizing, make up a part because recirculated water evaporates the water taken away.Water source of the industrial pond 46 as industrial cooling circulating water system,
Processed water of the moisturizing from chemical potassium permanganate composites.Industry cooling water pump 43 (or industry cooling water pump 44, industry cooling water pump
45) industrial colling is boosted, supplies each subsidiary engine user as cooling water via water main pipe, the cooling water for carrying heat returns
Water is back to recirculated water return water main pipe via return water main pipe, finally flows into recirculated water tower basin.Industry cooling in the embodiment of the present invention
Cooler in water system specifically includes that 3 solidifying pump coolers, 1 sealing oil vacuum pump cooler, 1 air compressor are cold
But device, 2 pre feedwater pump coolers, 2 starting furnace feed pump coolers and 1 boiler water circulating pump cooler.It is cold in industry
But the initial start stage of water pump when not yet establishing system pressure, needs to close water main pipe electrically operated gate 7, walks recirculating line,
The excessive motor supercurrent for causing industry cooling water pump of flow can be prevented in this way.Recirculating line is being walked just in industry cooling water pump
Chang Hou, it is pico- to open water main pipe electrically operated gate 7, and water main pipe exhaust electrically operated gate 9 is opened, it fills the water and is vented to system, wait be vented
Pipe flow out solid stream of water and there is no air discharge when, can standard-sized sheet water main pipe electrically operated gate 7, built to entire industrial cooling circulating water system
Vertical pressure.The return water of industrial cooling circulating water system enters recirculated water return pipe, enters recirculated water tower basin as a part of moisturizing, belongs to
Open-loop design.Therefore, it is necessary to constantly carry out moisturizing to industrial pond 46, water level in water pool is automatically adjusted by moisturizing tune valve.
In one embodiment, the water all the way in industrial pond 46 successively passes through the first industry cooling water pump 43 (or the second work
Industry cooling water pump 44 or third industry cooling water pump 45), that water main pipe electrically operated gate 7 enters the first solidifying pump cooler 32, second is solidifying
Pump the solidifying pump cooler 34 of cooler 33, third, sealing oil vacuum pump cooler 35, air compressor chillers 36, the first water supply
Pump fore pump cooler 37, the second feed pump fore pump cooler 38, first starting furnace feed pump cooler 39, second starts furnace
Feed pump cooler 40 and boiler water circulating pump cooler 41, the water flowed out from each cooler successively pass through return water main pipe, return water
Main pipe electrically operated gate 42 enters recirculated water return pipe.First industry cooling water pump 43, the second industry cooling water pump 44 and third industry
The usually interlocking of cooling water pump 45 uses, for example, if industry cooling water system can be guaranteed by only opening the first industry cooling water pump 43
System operates normally, then other two industry cooling water pump is then used as spare, in the first industry cooling 43 failure of water pump or is
System power output comes into operation when increasing.
Water all the way in industrial pond 46 successively pass through the first industry cooling water pump 43 (or the second industry cooling water pump 44,
Or third industry cooling water pump 45), recycling regulating valve 8 return to industrial pond 46.
In addition, the water all the way in industrial pond 46 successively passes through the first industry cooling water pump 43 (or the second industrial colling
Pump 44 or third industry cooling water pump 45), water main pipe electrically operated gate 7, from water main pipe exhaust electrically operated gate 9 be discharged, by system
In gas discharge.When carrying out water filling exhaust, keep starting current excessive to prevent from only starting an industrial colling, it can also be with
Start two industry cooling water pumps simultaneously, or also can star all three industry cooling water pumps.
Above-mentioned thermal power plant's industrial cooling circulating water system further includes four buttons: industrial cooling circulating water system programed logic behaviour
Make button A1, industry cooling water pump block push button A2, manual confirmation system exhaust completing button A3 and manual confirmation industry cooling
Water system can be with stop button A4.
Using industry cooling water pump block push button A2 can by the first industry cooling water pump 43, the second industry cooling water pump 44 and
The interlocking of third industry cooling water pump 45 is got up, this three industry cooling water pump mutual backup are made.For example, if only putting into operation
Two industry cooling water pumps 44 can be such that system operates normally, and the first industry cooling water pump 43 is spare as first, third industry
Cooling water pump 45 is spare as second.So when system is run, if cooling water needed for each cooler increases and only leans on the second work
When industry cooling water pump 44 is unable to satisfy, the first industry cooling water pump 43 and third industry cooling water pump 45 are according to pre-set
Logic is locked, the first industry cooling water pump 43 is first put into, if system operation can be met after the first industry cooling water pump 43 of investment
It is required that then third industry cooling water pump 45 is not required to come into operation；If still can not after the first industry cooling water pump 43 of investment
Meet system service requirement, then just needing to put into third industry cooling water pump 45.
