Description
Technical field
The present invention relates to the device for detecting temperature on a kind of air cooling island, particularly a kind of monitoring system that is used for the Direct Air-Cooled island surface temperature in thermal power plant.
Background technology
Cooling device is one of the important component part in thermal power plant, and the quality of cooling device operation is directly connected to the economy of power plant's operation.Because the thermal power plant water consumption is huge, brought bottleneck effect for the generating of rich coal water-deficient area.At present, the air cooling generation technology is generally adopted in the water-deficient area, has solved the problem of generating lack of water well.But air cooling generation technology ubiquity can not generate electricity summer at full capacity, needs antifreeze problem winter.Be the important season of its economy advantage of Direct Air-cooled Unit performance winter, but be in operation, and has performance driving economy and antifreeze conflicting problem.The operations staff generally is through the monitoring to the unit back pressure on air cooling island, condensing water temperature, each block adverse current section exhaust temperature, confirms the parameter that air cooling blower fan is adjusted.And prior art can only reflect monitoring result and the local conditions on air cooling island has had influence on its best economic performance of Direct Air-cooled Unit performance the limitation of these measuring point monitorings.
Summary of the invention
The invention provides a kind of monitoring system that is used for Direct Air-Cooled island surface temperature, solved the problem of winter the Direct Air-cooled Unit angles of science monitoring.
The present invention overcomes the above problems through following scheme:
A kind of monitoring system that is used for Direct Air-Cooled island surface temperature; Comprise air cooling island, boiler room and computer, be set with electronic thermal camera bracing frame on the top of boiler room, the thermal camera bracing frame is provided with incubator; In incubator, be provided with thermal camera; The camera lens of thermal camera is corresponding to the outer surface on air cooling island, and thermal camera is connected with computer-electrical, in computer, is provided with the extraction and the routine analyzer of infrared temperature signal; Electronic thermal camera bracing frame is connected with computer-electrical, with the automatic adjustment of the camera angle of the outer surface on the relative air cooling of the camera lens island of realizing thermal camera.
The adjustment angle of the adjustable angle of the camera lens of described thermal camera for can whole outer surfaces on air cooling island all being covered.
The present invention has intuitive and comprehensive; Improved accuracy and the specific aim of operations staff to air cooling apparatus adjustment in winter; Reduced the potential safety hazard of patrolling and examining intensity and night inspection of operations staff simultaneously to air cooling apparatus; Installation and easy to use, the air cooling island of applicable different capabilities unit.

Fig. 1 is a structural representation of the present invention.
Specific embodiment
A kind of monitoring system that is used for Direct Air-Cooled island surface temperature; Comprise air cooling island 1, boiler room 2 and computer 3,2 top is set with electronic thermal camera bracing frame 4 in the boiler room, and thermal camera bracing frame 4 is provided with incubator 5; In incubator 5, be provided with thermal camera 6; The camera lens of thermal camera 6 is corresponding to the outer surface on air cooling island 1, and thermal camera 6 is electrically connected with computer 3, in computer 3, is provided with the extraction and the routine analyzer of infrared temperature signal; Electronic thermal camera bracing frame 4 is electrically connected with computer 3, with the automatic adjustment of the camera angle of the outer surface on the relative air cooling of the camera lens island 1 of realizing thermal camera 6.
The adjustment angle of adjustable angle 7 for can whole outer surfaces on air cooling island 1 all being covered of the camera lens of described thermal camera 6.
Native system adopts infrared imaging sensor and powerful digital signal processor that the temperature signal of detected object is extracted; Be transferred on the PC computer through 100,000,000 network interfaces; And client software can accomplish measurand is carried out the shoot function with photo of recording of video, and to the accurate measurement of the temperature of measurand.This monitoring method is very directly perceived and effective, especially in the winter time infrared thermoviewer in the detection on air cooling island has been brought into play enormous function.Make the operation maintenance personnel more pointed to the adjustment of air cooling blower fan; Ensured the security of air cooling system operation effectively; And brought into play the advantage that direct air cooling system is moved in the winter time on this basis to greatest extent, improved the whole economic performance of unit.
