Embodiment Construction

[0018] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0019] The output high voltage U of the power supply device used for electrostatic dust removal 0 and the output high voltage current I 0 , constructed as attached figure 1 shown in rectangular form. According to the site conditions, the high-voltage voltage line 1 is set at the required horizontal position to limit the maximum value of 36 (U 0M ), the maximum value is used to ensure that the emission reaches the standard, and the electrostatic precipitator electric field does not have a breakdown discharge. When it is necessary to automatically track and control the dust concentration, it is only necessary to adjust the control current 37 (I 0M ) to the left and right of the vertical line 2, it is enough to set the working point 3 of normal dust removal at the proper position on the vertical line 2.

[0020] Horizontal line 1 is the ...

Abstract

This invention discloses a controlling method for automatic following dust concentration in electrostatic dust collection, in addition to the mating electric power unit. In the electrostatic dust collection system, it has no special dust concentration testing apparatus or special controlling apparatus, but through adjusting high voltage power output to automatic follow the dust concentration, which can ensure or improve the dust discharge concentration index. The controlling process is prompt and has good quality, and it can decrease the amount of labor greatly; in addition, the automatic following process is an electricity and energy saving process.

Description

technical field [0001] The invention relates to a control method for automatically tracking the concentration of discharged dust in electrostatic dust removal for environmental protection, and a matching power supply device. Background technique [0002] At present, due to the cumbersome detection and control of dust concentration, the cost of manpower and material resources, the complexity of the system, and poor reliability, most of the actual electrostatic dust removal process does not detect and control the dust concentration in real time, but The operator controls the dust emission concentration by manually controlling the size of the high-voltage power supply of the dust removal system based on visual inspection and experience. The specific method is: since the emission of smoke and dust can only be observed at a distance outside the workshop, it is estimated that the high pressure should be adjusted to a certain value, and then returned to the workshop, and the concen...
