Technical field
The utility model relates to a kind of temperature monitoring system, the temperature-visualized monitoring system of concrete a kind of Electric Factory Air-Cooling system.
Background technology
The thermal power plant air cooling system comprises the direct air cooled system indirect air cooling system of unifying, the effect of power station air cooling system is to use air rather than water-cooled condensing system as the cold junction of thermal power plant steam turbine, exhaust steam condensation after doing work in the steam turbine low pressure (LP) cylinder is become condensate water, circulate thereby finish an acting circulation and enter next acting.
Because adopting air cooling system compares with conventional humid-cool system, can economize on water more than 3/4, some rich coal water-deficient areas are that air cooling system has been put in the large turbo-type generator assembly of 30,60,1,000,000 multikilowatts in succession in the world, and air cooling system is also extensively adopted in the areas such as three Norths at home (northwest, northeast, North China) and Xinjiang.One of link that air cooling system circulates as the thermal power plant acting, stability and the security of its operation directly affect the operational efficiency of unit and the security of unit.Because the main cooling medium of air cooling system is air; therefore environment temperature is very large for the performance impact of air cooling system; the other area of dissipation of air cooling system very large (area of dissipation take the 300MW unit as the example air cooling system is about 900,000 square metres); the challenge of the maximum of air cooling system operation in winter is exactly antifreeze problem; if situation appears freezing in air cooling system; little tube bundle deformation or the bursting by freezing of air cooling then can make the time; large-area tube bank greatly then occurs and freeze situation, the heavy losses that will cause generating set accident to be shut down.The antifreeze problem of simple consideration air cooling system, raising that just need to the operation back pressure of unit is suitable, this will cause the coal consumption of unit to increase, therefore air cooling system preventing freeze in winter problem is the problem that each power plant's overriding concern solves, need to take various measures to guarantee the safe and stable operation of air cooling system, in this case, the conventional way that adopts is that the Current Temperatures of air cooling system is monitored, when low temperature occurring, can in time process, the concrete practice that adopts is to arrange a large amount of monitoring temperature points on the surface of tube bank, be used for monitoring the Temperature Distribution situation of tube bank, and by signal acquiring system the temperature monitoring signal delivered to Control Room.But this monitoring means can not satisfy air cooling system tube bank temperature comprehensively to be monitored, and there is following shortcoming in it:
(1) because the area of dissipation of monitoring is larger, the temperature spot of the monitoring that needs more (needing about 1800 measuring points as an example of the 300MW unit example), construction and repair and maintenance workload are larger;
(2) system of this monitoring is the tube bank temperature of supervision part also, can not accomplish the comprehensive monitoring temperature of air cooling system tube bank, and the amount of measuring point is larger simultaneously, freezes the position to operations staff's maintenance, maintenance and accurate location and brings very large difficulty;
(3) temperature point that lays is laid in and restrains the surface, will increase windage, can the heat exchange property of tube bank be affected;
(4) temperature point that lays brings certain obstruction when tube bank being carried out the water flushing.
The utility model content
Can not comprehensive monitoring and the larger problem of monitoring amount for the monitoring of the Electric Factory Air-Cooling system temperature that exists in the prior art, the utility model provides a kind of camera system of utilizing to realize air cooling system visual temperature monitoring system.Concrete scheme is as follows: the visual temperature monitoring system of power station air cooling system, it is characterized in that, comprise and be arranged on the air cooling system double vision monitoring thermal infrared imager that can realize visible light and two kinds of functions of thermal imaging everywhere, be connected and analyze the control system of its data with double vision monitoring thermal infrared imager, be connected and show the acoustic-optic alarm the when display device of current air cooling system real-time status and air cooling system temperature reach critical point with control system.
In order to make things convenient for transfer of data: described double vision monitoring thermal infrared imager is sent to control system by network with data.
Check for making things convenient for data: described control system also is connected with print-out device.
For convenient tube bank is removed contamination: described control system also is connected with the system that removes contamination of cleaning air cooling system surface dirt.
The utility model utilizes based on the special-purpose monitoring temperature of infrared thermal imaging technique uses thermal imaging and the two monitoring camera-shooting equipment of visible light, communication network device, thermal imaging server and thermal imaging monitoring and programming software to form temperature control system.Realize round-the-clock, real-time, the visual temperature monitoring of air cooling system tube bank temperature and the function that possesses automatic detecting, warning and monitoring picture is analyzed.Control system of the present utility model has the function of the good demonstration of HMI operation interface real time data, warning and data analysis.
