Description
Technical field
The present invention relates to a kind of all-sealed dreg removing system of coal pulverizer, the motor hermetically sealed dreg removing system of overhead coal pulverizer of a kind of all-sealed discharge of coal pulverizer pebble coal being applied in field of thermal power.
Background technology
At present,Medium-speed pulverizer in the pulverized coal preparation system of thermal power plant, in the running of coal-grinding, always has some to be difficult to the granular material ground, and these granular materials are referred to as pebble coal.During medium-speed pulverizer coal-grinding, pebble coal can be separated, enter the pebbles coal slag box on the downside of medium-speed pulverizer, there is oblique tubular pebble coal outlet down the lower end of pebbles coal slag box, pebble coal outlet is connected with residual cake valve, closing in medium-speed pulverizer when residual cake valve is for keeping not discharge, medium-speed pulverizer to be opened blow-off valve in running off and on and discharge the pebble coal in pebbles coal slag box from pebble coal outlet, and the pebble coal of discharge needs to deliver to outdoor coal cinder yard in the Factory Building at medium-speed pulverizer scene.
In the Mill Systems of existing operation, most employing buffers box dreg removing system on the spot, i.e. the slag notch order at coal pulverizer arranges residual cake valve, buffering dreg-storing box, lower dreg discharging valve, opened type slag discharging vehicle, and its deslagging mode, for discharge on the spot, is manually cleared；Due to pebble coal finally slagging tap, in transfer process airborne dust serious, cause working condition very severe in Factory Building, have a strong impact on power plant environment health and safe and civilized production, additionally, coal pulverizer longtime running and residual cake valve are frequently opened, cause common residual cake valve heavy wear, internal hemorrhage due to trauma and the phenomenon that leaks outside are universal, the a large amount of dust leaked out, severe contamination surrounding, reduce safety and the service life of equipment.The defect of the box dreg removing system on the spot of buffering of the prior art specifically has:
1, due to coal pulverizer longtime running, buffering dreg-storing box volume is smaller, and coal pulverizer needs to open and close continually residual cake valve in running, and common slag-discharging valve is easy to internal hemorrhage due to trauma and leaks outside.Dust is caused to be directly leaked to outside valve when leaking outside；And during internal hemorrhage due to trauma, also stone cannot be stoped when i.e. turning off valve to continue discharge in coal, if slag discharging vehicle splicing may result in part pebble coal not in time and is directly discharged on ground, the dust not only affecting follow-up work but also kick up because of valve leaks also can serious environment pollution, this is the major reason that existing working site is polluted.
2, the pebble coal discharged from buffering dreg-storing box slag notch open discharges on the spot, and emission also can carry substantial amounts of high-temperature dust, causes tapping process dust from flying, causes environmental pollution and potential safety hazard.This is the main cause that existing working site is polluted.
3, from coal pulverizer slag-drip opening to slag case, having valve, Flange joint, internal Non-smooth surface is continuously coupled, therefore, when there being foreign body in tapping process, will block Residue extraction pipeline, finds " to flood mill " not in time, is likely to result in more major accident.Remove the foreign body in scum pipe, need coal pulverizer out of service.Have a strong impact on coal pulverizer properly functioning, increase operation costs.
Due to the existence of above-mentioned phenomenon, the equipment in Factory Building is chronically in severe dust atmosphere, electrical apparatus control system, all kinds of operated pneumatic valve, and electromagnetic valve, hydraulic valve are easy to damage, and causes maintenance, safeguards and replacement cost increase.The more important thing is, such working environment severely compromises the health of human body of staff in Factory Building.Thus, it is desirable to provide a kind of can fundamentally solve the brand-new all-sealed dreg removing system of coal pulverizer that pebble coal discharges on the spot.
