Coal dust classifier is one of most important parts in mill coal pulverizer system, and the quality of its structure and performance has significant impact to life-span, power consumption and the boiler combustion efficiency etc. of coal pulverizer.On the one hand one coal dust classifier reasonable in design is wanted timely qualified coal dust to be delivered to boiler, on the other hand undesirable for fineness pulverized coal sieve is elected so that it is continue to mill in returning coal pulverizer.Coal dust classifier primary structure is: centered by coal spout, is externally provided with outer conical shell, inner conical housing, and the top of inner conical housing is respectively arranged with to be had the coal powder distributor case of discharge, be folded to door.During use, between wind coal dust to outer conical shell, inner conical housing, then through being folded to door, around the inner chamber rotating centrifugal of inner conical housing after, discharge on coal powder distributor case is discharged；Granule bigger in coal dust then falls within the bottom of inner conical housing, is then discharged out.But this equipment exists major defect at present is that coal dust rotates the centrifugal force produced not quite around inner conical inner walls, and therefore coal dust separation granule is thin, and uniformity is the poorest.
Power Plant in China coal varitation is frequent at present, and a lot of power plant are all that coal blending ginseng is burnt, and in order to meet the requirement of peak load regulation, coal pulverizer must have the ability adjusting fineness of pulverized coal in time；And along with more and more higher to power plant for energy conservation environmental requirement of countries in the world, many units are all using low NOxDraining technology, in order to reduce NOxOperating cost is not the most increased, it is necessary to making fineness of pulverized coal and uniformity reach higher requirement, traditional coal dust classifier cannot meet above-mentioned use requirement with fly ash emission amount.
Utility model content
The purpose of this utility model is to provide a kind of coal dust disconnecting gear for efficient hot water boiler, and the fineness of pulverized coal that this device is separated is higher, uniformity preferable, and separation efficiency is high, speed is fast.
The purpose of this utility model is achieved through the following technical solutions:
A kind of coal dust disconnecting gear for efficient hot water boiler, including cylinder, coal dust powder inlet pipe, fine breeze flour extraction pipe, rough coal powder powder-returning funnel, rough coal powder row's tube cell, described cylinder bottom device coal dust powder inlet pipe, top device fine breeze flour extraction pipe；Three pieces of sloping baffles being tilted to the right of end device under the internal left wall face of described cylinder, two pieces of sloping baffles being tilted to the left of end device under internal right wall；Separation chamber in described cylinder inner upper end device, two ends, left and right, described interior separation chamber are respectively fixed on cylinder inwall by one piece of fixed metal plate, and upper end, described interior separation chamber is by row's tube cell attachment means fine breeze flour extraction pipe on cylinder top.
Described cylinder bottom returning apparatus rough coal powder powder-returning funnel, described rough coal powder powder-returning funnel bottom device rough coal powder row's tube cell.
Described sloping baffle is the stainless steel metal screen plate with intensive hollow out mouth.
Under the internal left wall face of described cylinder, under three pieces of sloping baffles being tilted to the right wall right with inside of end device, two pieces of sloping baffles being tilted to the left of end device are arranged separately, and described two pieces of sloping baffle devices being tilted to the left are between three pieces of sloping baffles being tilted to the right.
Described interior separation chamber is a miniature cyclone separator, and top connects row's tube cell, and bottom arranges coarse powder and returns powder mouth.
Described coal dust powder inlet pipe is made up of straight tube pipe, conical pipe, and described straight spool upper end connects conical pipe, and described conical pipe upper end connects cylinder.
The beneficial effects of the utility model: a kind of coal dust disconnecting gear for efficient hot water boiler of the present utility model, the fineness of pulverized coal that this device is separated is higher, uniformity preferable, and separation efficiency is high, speed is fast.
A kind of coal dust disconnecting gear for efficient hot water boiler of the present utility model, in use, the coal dust ground through coal pulverizer first passes through coal dust powder inlet pipe and enters in cylinder, first bigger in sloping baffle gear coal breakage powder granule, bigger pulverized coal particle is along the incline direction landing of sloping baffle, eventually fall in rough coal powder powder-returning funnel, discharge through rough coal powder row's tube cell, and through sloping baffle, the coal dust not being blocked then goes successively to miniature cyclone separator, after cyclonic separation, the trickle coal dust of composite demand is discharged from fine breeze flour extraction pipe and is used, isolated undesirable coal dust, return powder mouth through coarse powder to discharge, fall on sloping baffle, incline direction landing along sloping baffle, eventually fall in rough coal powder powder-returning funnel, discharge through rough coal powder row's tube cell.
