Abstract

The invention discloses a sound wave temperature-measuring sounding device and a receiving device. The sound wave temperature-measuring sounding device comprises a sounding chamber and a nozzle arranged in the sounding chamber, wherein an air inlet end of the nozzle extends out of the sounding chamber; a reed is arranged in the sounding chamber; the reed has a cantilever structure with one end being fixed; and the tail end of the reed is opposite to an air outlet end of the nozzle. A sound wave temperature-measuring receiving device comprises at least one receiving tube front section and one receiving tube rear section, wherein the receiving tube front section and the receiving tube rear section both have a drum-shaped structure. According to the invention, the nozzle, the reed and the sounding chamber are cooperated for generating a high-decibel and high-frequency sound source, and then the receiving device is used for receiving the temperature for monitoring a boiler furnace; the device has the advantages of simple structure, low failure rate and high measurement accuracy; and the device can be widely applied to the field of temperature measurement of the high temperature furnace.

Description

technical field [0001] The invention relates to the field of boiler furnace temperature measurement, in particular to an acoustic temperature measurement and sound emitting device and a receiving device. Background technique [0002] The principle of furnace acoustic temperature measurement is mainly to solve the temperature field by using the speed change caused by the action of sound wave in the gas medium and the gas temperature. There are two types of traditional furnace temperature measurement devices: contact type and non-contact type: contact type belongs to the traditional measurement method, such as telescopic thermometer, the probe penetrates into the furnace for a long time, is heavy, easily deformed and jammed, has a high failure rate, and cannot be continuously When put into use, the measured temperature is discontinuous. The furnace wall measurement is only for the water wall. These traditional measurement methods are difficult to truly reflect the temperatur...
