Title:
ONLINE PULVERIZED-COAL CONCENTRATION REGULATOR AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/021511
Kind Code:
A1
Abstract:
Disclosed are an online pulverized-coal concentration regulator and a method therefor. The pulverized-coal concentration regulator is installed at the front end of a pulverized-coal pipe (8), a pulverized-coal concentration detector is arranged in the pulverized-coal pipe (8), a control system is comprised in the pulverized-coal pipe, and the pulverized-coal concentration detector is connected to a signal input end of the control system; a top plate (6), an adjusting rod (1) and a pulverized-coal baffle plate (5) are further comprised in the regulator, the top plate (6) is provided with a mounting hole for fixedly mounting the front end of the pulverized-coal pipe (8) and a through hole for the pulverized-coal baffle plate (5) to pass therethrough, and a connector (7) is arranged between the adjusting rod (1) and the pulverized-coal baffle plate (5) and is connected to both the adjusting rod (1) and the pulverized-coal baffle plate (5); and a guide device (3) is further comprised in the regulator, the guide device (3) is slidably connected to the pulverized-coal baffle plate (5) and fixedly connected to the top plate (6), the top plate (6) is provided with a flow guide plate (4), and the flow guide plate (4) is slidably connected to the pulverized-coal baffle plate (5). The pulverized-coal concentration regulator can control the pulverized coal concentration difference at about 5%, and can reduce the possibility of flow turbulence of upstream pulverized coal and prevent the accumulation of pulverized coal; the coal intake amount of the pulverized-coal pipe (8) is accurately controlled by means of the degree to which the pulverized-coal baffle plate (5) is opened; and the regulator has a simple apparatus structure, and is safe and reliable.
