Waste heat boiler leakage detection method and device

Abstract

The invention relates to the technical field of production equipment operation and maintenance, in particular to a waste heat boiler leakage detection method and device. The waste heat boiler leakagedetection device comprises a sampling tank and a liquid separation tank, wherein the top of the sampling tank fixedly communicates with a waste heat boiler steam production sampling pipeline, and theupper portion of the liquid separation tank fixedly communicates with a liquid drainage pipeline; and when waste heat boiler leakage detection is carried out, the sampling tank and the liquid separation tank are connected through a discharging pipeline, the non-condensable gas in the liquid separation tank is sampled at a gas sampling valve, it is further judged that leakage exists in a waste heatboiler, and the accumulation amount of the non-condensable gas in the liquid separation tank and the leakage amount of the non-condensable gas in steam generated by the waste heat boiler are calculated. According to the method and the device, the leakage condition of the waste heat boiler can be monitored in real time, whether the waste heat boiler leaks or not can be effectively detected, the leakage amount can be roughly calculated, the purpose of effective monitoring is achieved, a basis is provided for judgment of leakage of the waste heat boiler, and the method has the advantages of being convenient to operate and simple and efficient.

Description

technical field [0001] The invention relates to the technical field of production equipment operation and maintenance, and relates to a waste heat boiler leakage detection method and device. Background technique [0002] Waste heat boilers are also called waste heat boilers, which use various high-temperature waste gases to heat water to generate steam or hot water, namely steam waste heat boilers and hot water waste heat boilers, and then use the generated steam or hot water to achieve the purpose of waste heat reuse. The authorized patent "Judgment Method for Water Leakage of Built-in Waste Heat Boiler in Large Flue of Sintering Machine" (CN 106224931 B) collects the temperature value data information in the upper and lower walls of the large flue of sintering machine behind each group of heat exchangers in real time through the acquisition unit, and will The data information is processed and accumulated, and by observing the variation trend of the temperature value deviat...
