Compared to prior art, a kind of dust bonding power determinator provided by the invention and method thereof, wherein corona wire is applied in described dust bonding power determinator, has volt-ampere characteristic good, to the strong adaptability of dust specific resistance change, the advantage that cut-off voltage is high.It is simple that dust bonding power determinator provided by the invention has structure, and with low cost, simple to operate, result is advantage accurately.
[accompanying drawing explanation]
Fig. 1 is the structural representation of a kind of dust bonding power of the present invention determinator.
[embodiment]
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is described in more detail.
Refer to Fig. 1, the invention provides a kind of dust bonding power determinator, comprising:
The corona wire 1 set gradually up and down, disk 2, buncher 3;
Described corona wire 1 connects high-voltage power supply 4, and itself and disk 2 are horizontally disposed with, and form gap 5 between described corona wire 1 and disk 2;
Described disk 2 is steel plate, this disk 2 ground wire, this disk 2 is vertical in buncher 3 rotating shaft with motor, the end that the rotating shaft of described buncher 3 contacts with disk 2 is provided with insulating disc 6, this insulating disc 6 produces electric charge for avoiding between buncher 3 rotating shaft and disk, and it is charged to affect dust on disk 2, thus cause measurement result inaccurate;
Described buncher 3 is provided with the monitoring device (not illustrating in figure) for its rotational speed omega of Real-Time Monitoring.
Especially, also comprise: the speed control 7 arranged away from disk 2, it is located in buncher 3 rotating shaft.
Especially, the voltage of described high-voltage power supply 4 is 25 ~ 55KV, so arranges, and dust is produced charged, thus is conducive to the work of electrostatic precipitator.
The present invention also provides a kind of dust bonding power assay method, comprises the following steps:
S1: the installation of dust bonding power determinator;
S2: calculate the cohesive force F between dust
1 glues, computing formula is as follows:
Wherein, m is quality, the μ of dust
sfor maximum static friction force coefficient, ω be buncher rotating speed, r is the distance of dust apart from buncher spindle central; The maximum static friction force coefficient of various dust can be consulted relevant reference and obtain, and motor speed and dust are to spindle central apart from can directly measure, and dust quality by measuring its volume, then can be multiplied by its bulk density and draw;
S3: according to the F calculated in S2
1 gluescalculate unit area 1mm
2the size of dust layer cohesive force.
Especially, described step S1 specifically implements in accordance with the following methods:
Dust is placed on disk, then by dust bonding power apparatus and dust integrally fixed mount on buncher, dust and buncher are together rotated.
The course of work, in time working, is first placed on disk by dust; Then open high-voltage power supply, high-voltage power supply carry out from low to high regulating until produce spark discharge; Then buncher is started working, and now dust is under the effect of buncher rotating shaft, starts to rotate, and such dust is just subject to centrifugal force f (f=mr ω
2) effect, when the cohesive force of centrifugal force just greater than dust, dust will fly out from steel plate, now, measures the rotational speed omega of buncher and the dust distance r apart from buncher spindle central; Both the cohesive force size of dust layer can have been measured afterwards by formula (1).
Cohesive force F between dust and pole plate
stickyfollowing formulae discovery then can be utilized to draw:
F
sticky=2F
1 glues(2).
Should be understood that, in those skilled in the art, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
