Abstract
The on-line monitoring method for boiler expansion includes mounting displacement sensors to ends of boiler header to measure the expansion displacement of the header, transmitting the output signals of the displacement sensors to computer via cable, recording the displacement data in the computer with set program, monitoring the boiler expansion via display screen and sending warning signal in case of exceeding the set expansion limit. The present invention provides technological support and monitoring means for the safe running and analysis of boiler.
Description
Technical field:
The invention belongs to the safety monitoring technology field of boiler operatiopn, in particular a kind of on-line monitoring method for boiler expansion.
Background technology:
At present, in thermal power plant and industrial production, moving a large amount of high pressure, super-pressure and special boiler, a lot of boiler explosion accidents were also taking place, serious threat safety in production and personal safety.Aspect the boiler explosion precaution, though there are a lot of relevant rules and regulation in country, but boiler is whole owing to be heated or metal fatigue, distortion that produces under the HTHP situation and expansion detection technique are perfect not enough, safe operation state evaluation and the not enough science of analysis data to boiler are unfavorable in time analyzing and preventing accident.
Summary of the invention:
Technical problem to be solved by this invention is: provide that a kind of detection technique is perfect, safe operation state evaluation and analyze data science, the on-line monitoring method for boiler expansion timely of analyzing and prevent accident.
Method of the present invention comprises the following steps:
1. displacement transducer is installed in the two ends of boiler header respectively, measures the expansion displacement of header to two ends;
2. the output signal of displacement transducer is incorporated into computer by cable;
3. computer writes down the displacement situation of header automatically by the program of setting, and by computer display, monitors the boiler expansion state, when expansion overshoot value, reports to the police automatically.
Good effect of the present invention is: technical support and supervision means are provided, detection technique is perfect, safe operation state evaluation and analyze data science, analyze and prevent accident in time, embodied the safety in production policy of putting prevention first especially, also be the security of analyzing the boiler operatiopn state, boiler carried out the effective ways of safety evaluatio.
Description of drawings:
Fig. 1 is monitoring point position figure of the present invention;
Fig. 2 is the logic diagram that apparatus of the present invention constitute.
The specific embodiment:
See figures.1.and.2, displacement measurement element 2 is installed on the fixed support of each termination correspondence of boiler header 1 respectively, adjust the displacement transducer position in cold conditions, make it to contact with header expansion transmission bar 3 and sensor is fixed, when ignition of the boiler moves, temperature raises gradually, expansion displacement increases, then opposite during blowing out, the digital data transmission that header converts displacement variable (comprising abnormality) to through displacement transducer to the expansion at two ends is to automatic production record and in-service monitoring, overrun alarm system, the just computer in a distant place.On the picture of computer, just show boiler expansion picture and parameter, the actual measurement boiler in start-up course, by cold conditions to the nominal operation state, header expansion 85mm, with initial sum is consistent with the chi measurement result finally, and whole expansion process and variation tendency also are perfectly clear.If transfinite, then show and send voice suggestion with red numeral.General this computer centre control room.If it is undesired to find to expand, in time point out the person on duty to ascertain the reason, in time get but measure, the accident that prevents takes place.
