Description
Technical field
The utility model is related to power plant air cooling system technical field of temperature measurement, especially a kind of to be used for air-cooled temperature field
The fixing bracket of the lossless installation sensor of monitoring system.
Background technology
In " three Norths " in China area, i.e. North China, northeast, the Northwest, rich coal resources, but water resource is very deficient
Weary, compared with traditional humid-cool system, the cooling capacity of Direct Air-Cooling Technology is much smaller than the cooling capacity of water, but Direct Air-Cooled skill
Art is very low to the consumption of water, and water resource can be saved every year more than 90% using humid-cool system using air cooling system ratio,
Direct Air-Cooling Technology is the exhaust steam in steam turbine cooling technology that rich coal water-deficient area thermal power generation unit mainly uses.Therefore, thermoelectricity
There are wide application prospects in these rich coal water-deficient areas for factory's Direct Air-Cooling Technology.
Large-scale power station direct air cooled condenser main function is that the steam exhaust that turbine low pressure cylinder comes is big by 1 or 2
Blow-off line is guided at the direct air cooled condenser on the air cooling platform outside steamer computer room, by carry the heat-exchanging tube bundle of fin with
The cold air that axial flow blower is sent carries out heat exchange, and the steam condensation Cheng Shui in heat-exchanging tube bundle is made to enter collector pipe, passes through condensation
Water pump returns to boiler feed system.
Research shows that during air cooling tubes condenser winter operation, since heat exchange initial temperature differences ITD values are very big, heat-exchanging tube bundle dissipates
Thermal energy power is remarkably reinforced than summer, easily occurs generating freezing phenomena because of supercooling.It is reduced in particular with load and environment temperature,
Distribution of steam inside air-cooled tube bank starts, in uneven state, heat-exchanging tube bundle temperature distributing disproportionation to be also resulted in, if condensation water
Supercooling is easy for freezing.The running solution of power plant at present：First, winter sends someone to carry out manual inspection, manual inspection
Working environment is severe, and labor intensity is big, and most importantly manual inspection cannot accomplish real-time online, and operations staff cannot timely root
It is adjusted in real time according to field condition.Second is that improving unit operation back pressure when running in winter, unit is in high back pressure run mode, passes through increasing
Add the throttle flow of air cooling tubes condenser to improve the antifreeze ability of heat-exchanging tube bundle, directly contribute generating set in this way and contribute and wind turbine consumption
Work(increases, and coal consumption increases, and the economy of unit operation and safety are substantially reduced.
At this stage for the monitoring of air-cooled radiating surface, on-line testing is used for by portioned product and restrains temperature, sensor is big
Mostly cable for measuring temperature is fixed by arranging steel wire rope or borrowing fixed band iron.Both methods all exists to be surveyed with actual needs
Warm face has the problem of a certain distance, testing temperature is inaccurate and sensor to contact the problem of bad with tube bank, measures temperature simultaneously
Inaccuracy so directly has an impact temperature monitoring, and indirectly the guidance given the judgement of operations staff and subsequently adjusted is produced
Raw great deviation.
