Intelligent blowing type wind speed measuring system for primary powder pipe, and blowing method of system

The invention relates to an intelligent blowing type wind speed measuring system for a primary powder pipe and a blowing method of the system, and aims to solve the problems existing in an existing reverse blowing type primary powder pipe wind speed measuring technical scheme. Intelligent blowing type wind speed measuring equipment installed on the single primary powder pipe comprises a wind speedmeasuring device, a first pressure leading pipe, a second pressure leading pipe, a first manual valve, a second manual valve, a third manual valve, a pressure transmitter, a terminal plate, a differential pressure transmitter, an electromagnetic adjusting valve, a fourth manual valve, an instrument compressed air pipeline, a power supply, an analog quantity output clamping piece, an analog quantity input clamping piece, a DCS processor and an operation device. In a DCS control mode, a blowing point position can be judged automatically according to a wind speed deviation of each primary powderpipe of each coal mill, a
