In addition the flue dust detection device can be with the concentration of flue dust in real-time detection to operating room 2, when flue dust in operating room 2
When the fast speed of generation, the dust concentration that flue dust detection device detects can be higher, otherwise the dust concentration that detects can be compared with
Low, the synchronizing information that flue dust detection device can will test feeds back the then control system meeting into the control system of main dust removal machine 1
Blower is controlled according to the information of Real-time Feedback reaches corresponding required revolving speed, when the dust concentration of detection is higher, blower
Revolving speed is higher, so that the flue dust in operating room 2 be made quickly to remove；When concentration is lower, the revolving speed of blower is accordingly lower, avoids making
At energy dissipation.Thus it is not only able to satisfy pick-up performance, but also energy saving intelligent control can be reached.
Finally, it is stated that the above embodiments are merely illustrative of the technical solutions of the present invention rather than is limited, to the greatest extent
Pipe is described the invention in detail referring to preferred embodiment, it should be appreciated by those of ordinary skill in the art that can be right
Technical solution of the present invention is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be contained
It covers in scope of the presently claimed invention.
