Automatic measurement device for cold aerodynamic field of boiler

Abstract

The invention relates to an automatic measurement device for a cold aerodynamic field of a boiler. The automatic measurement device comprises a wind speed probe, a data acquisition device connected with the wind speed probe, a main control unit connected with the data acquisition device and a support fixing device for fixing the wind speed probe, wherein the support fixing device comprises a support, a vertical supporting rod arranged on the support and a transverse supporting rod connected with the vertical supporting rod via a fixing clip; the wind speed probe is arranged on the transverse supporting rod; the wind speed probe, the data acquisition device and the main control unit are connected, and the wind speed probe is fixed by the support fixing device at the same time; the automatic measurement device is simple and convenient to install, accurate in measurement, smooth in data transmission and high in working stability, avoids measurement of testers, brings great convenience to field test, shortens the experimental time, and greatly improves the working condition of experimenters.

Description

technical field [0001] The invention relates to an automatic measuring device for the cold air dynamic field of a boiler. Background technique [0002] Boiler cold test is an important test item for power plant boilers. There are many shortcomings in traditional testing methods: a. The working environment is poor. The noise in the furnace is loud, the dust is flying, the summer is extremely hot, and the winter is cold, which has caused great harm to the health of the test personnel. b. High labor intensity. The test personnel climbed up the ladder in the harsh environment, and faced the wind speed of 30-50m / s to measure the wind speed at high altitude, which was not only labor-intensive, but also dangerous. c. The test takes a long time. There are a lot of boiler burner nozzles, and it is necessary to manually measure each nozzle at multiple points in each working condition. In order to obtain a complete damper characteristic curve, it is necessary to measure multiple wo...

Problems solved by technology

There are many shortcomings in traditional testing methods: a. Poor working environment

c. The test takes a long time

There are a lot of boiler burner nozzles, and it is necessary to manually measure each nozzle at multiple points in each working condition. In order to obtain a complete damper characteristic curve, it is necessary to measure multiple working conditions, so it takes a long time. In order to ensure The quality of the test and the safety of the test personnel. During the test, proper rest is required, which not only increases the test time, but also increases the power consumption of the fan.

d. Low test accuracy

The hand-held instrument measures the wind speed of tens of meters per second, the arm shaking is unavoidable, and naturally the stability of the instrument and the correct angle cannot be guaranteed, and the test accuracy is greatly affected
