The invention discloses an air volume measuring device and method for a complex air channel arrangement environment. The air volume measuring device comprises a measuring device shell arranged in a measured air channel, wherein a partition air channel wall used for dividing the air channel into a plurality of partition air channels is arranged in the shell, an air volume measuring pipe is arranged in the partition air channel wall, and an air volume measuring element is arranged at an end of the air volume measuring pipe, a plurality of separated air duct walls are arranged in the shell, the measured air duct is divided into a plurality of separated air ducts, the air volume of each separated air duct after rectification of the separated air ducts is accurately measured, and then summation is performed to obtain the accurate air volume of the total air duct, so a problem of inaccurate air volume measurement in a complex air duct arrangement environment is solved; accurate adjustment of combustion and operation of the coal mill and investment of related automatic control systems such as an automatic control system of the coal mill can be achieved.
Description
technical field [0001] The invention belongs to the field of thermal power generation, and relates to an air volume measurement device and method for complex air duct layout environments. [0002] technical background [0003] The problem of accurate air volume measurement in complex air duct layout environments has always plagued the measurement of flue air volume in power plant flue air systems. In particular, the problem of measuring the secondary air at the entrance of the coal mill and the furnace is particularly prominent. The air volume cannot be accurately measured, which not only affects the operation adjustment, but also affects the input of the air volume and the automatic control system of the coal mill. The reason for the problem is: limited by the space layout, the air duct layout is complicated, there is not enough space to arrange the straight pipe section that can meet the measurement conditions, there are many elbows at the entrance and exit, the flow field...
