Abstract

The invention discloses an online measuring method of the fineness of automatic sampling pulverized coal. The method comprises the following steps of driving a sampling gun to stretch into a pulverized coal pipeline by using a control mechanism, controlling the negative pressure and suction of an air extracting mechanism to realize sample pulverized coal particles, and enabling the pulverized coalparticles to be collected under the action of a cyclone separator; controlling the collected pulverized coal particles by using the control mechanism so as to be processed into dropping pulverized coal fluid with thin surfaces via using a pulverized coal particle processing mechanism, collecting pictures by using an image collecting mechanism, and analyzing the size and distribution of the pulverized coal particles from pictures by using an image processing unit; the control mechanism is used for controlling a pulverized coal recycling mechanism to recycle the pulverized coal particles collected by the image collecting mechanism to a raw pulverized coal pipeline; the measuring device comprises a sampling mechanism for collecting the pulverized coal particles, the suction mechanism, the pulverized coal particle processing mechanism, the image collecting mechanism for collecting the pictures of the pulverized coal particles and the pulverized coal recycling mechanism for recycling the pulverized coal particles. The measuring device can be used for online measurement of the fineness of the pulverized coal in real time, does not need people to participate in measurement, saves both time and labor, is high in measurement accuracy and resistant to pollution, and can be used for a long time.

Description

technical field [0001] The invention relates to the technical field of pulverized coal fineness measurement, in particular to an online measurement method and a measuring device for pulverized coal fineness by automatic sampling. Background technique [0002] Energy and the environment are the material basis for human survival. With the rapid development of science and technology and the improvement of living standards in human society, more energy must be consumed. This makes our energy industry, especially power generation companies, urgently need to improve combustion Efficiency, improve efficient and clean energy supply; at the same time, the global warming of the environment and the implementation of ultra-low emission standards require power generation companies to improve coal combustion efficiency and reduce emissions. [0003] The detection of pulverized coal particle size is a particularly important part of the detection of combustion parameters in thermal power ge...
