What is the role of hydraulic coupling in the application of all kinds of fans in the coal preparation plant?
The coal preparation plant has many fans and pumps, and according to the requirements of the process, most of these fans and pumps need to be adjusted.
According to the different regulation condition, the energy saving rate is about 15%~ 25%.
Since it is not intermittent operation, the energy saving rate is not very high, but compared with the regulation of throttling and release regulation, the energy saving is significant.
Fan of furnace to produce hot flue gas after the sedimentation chamber to remove Mars, due to the lower part of the main fan to dry desiccant, wet material from the raw coal from the top drying machine, belt conveyor, is expected to be evenly most from the bottom of the dryer after drying comprised output belt conveyor, a small part of the department of materials with the air into the bag filter, filter material recycling products as isolated.
The gas after purification is expelled by the exhaust pipe.
After drying, the coal belt conveyor is used to select the coal belt conveyor, and the output of the coal and gangue is respectively carried out by belt conveyor.
In the above joint process system, there are seven hydraulic coupling drives and speed adjustment.
The purpose is to adjust the energy saving, to adapt to the process requirement and the condition of belt conveyor type choose limited moment more around hydraulic coupling, the purpose is to solve the problem of light load starting and overload protection, prolong the service life of belt conveyor.
Some of the coal preparation plant will dry box dry separation, but the use of the hydraulic coupler is similar to this.
