Device for measuring flow of pulverized coal conveyed by wind

Abstract

The invention provides a device for measuring flow of pulverized coal conveyed by wind. The device comprises a measuring pipe, a measuring instrument and a linear drive mechanism, wherein the measuring pipe is connected onto the pulverized coal conveying pipeline, and a measuring branch pipe communicated with measuring pipe is arranged on the measuring pipe; the measuring instrument is slidably assembled in the measuring branch pipe, and the inner end of the measuring instrument is a measuring end; the outer end of the measuring instrument is a signal output end, and the measuring end of the measuring instrument extends to the inner side of the measuring pipe; the linear drive mechanism is fixedly arranged at the outer side of the measuring branch pipe, and the drive end of the linear drive mechanism is connected with the measuring instrument. The device for measuring the flow of pulverized coal conveyed by wind provided by the invention has the advantages that the sampling measurement positions of the measuring instrument are automatically changed under the control of a control system without manual adjustment, so that a large number of manpower is saved, and the multi-position sampling measurement can be simultaneously carried out on the devices for measuring the flow of pulverized coal conveyed by wind on all pulverized coal pipelines, and thus the burning of each pulverized coal furnaces can be precisely and timely controlled.

Description

technical field [0001] The invention belongs to the field of equipment related to thermal power generation, and in particular relates to a device for measuring the flow of pulverized coal by wind. Background technique [0002] At present, most thermal power plants mainly use pulverized coal furnaces to provide heat energy. Pulverized coal furnaces need to provide pulverized coal to them through pulverized coal transportation pipelines. Controlling the flow of pulverized coal in pulverized coal transportation pipelines is the main control method for the combustion of pulverized coal furnaces. Therefore, the pulverized coal flow measuring instrument can detect the pulverized coal flow in the pulverized coal conveying pipeline, which is very important for controlling the pulverized coal furnace. The existing pulverized coal flow measuring instrument is all slidingly assembled in the measuring branch pipe on the measuring pipeline , when the pulverized coal flow needs to be meas...

AI Technical Summary

Problems solved by technology

Due to the large number of pulverized coal furnaces in thermal power plants and related air-conveyed pulverized coal flow measurement devices, a large amount of manpower is required to measure the flow of each pulverized coal pipeline. The sampling and measuring position of the pulverized-coal flow measuring device is changed at the same time, so it is impossible to measure the pulverized-coal flow in each pulverized-coal conveying pipeline at the same time and measure at any time, and then it is impossible to realize accurate and timely control of the combustion of each pulverized-coal furnace
