Description

A kind of sound Assembled rotary segregation apparatus
Technical field
This utility model relates to coal dust separation technology field, a kind of sound Assembled rotary segregation apparatus.
Background technology
After carrying out denitration and low NO transformation, boiler fly ash combustible content increases, though carrying out firing optimization and coal mixing combustion through various means, unburned combustible in fly ash is still between 6-8%, because low NO belongs to anoxycausis, if unburned combustible in fly ash to be reduced is necessary for improving fineness of pulverized coal so that the burn-off rate of coal dust.
In prior art in boiler milling system, the performance of mill separator directly affects economy and the safe operation of boiler, for a long time mill separator also exist that comprehensive separation efficiency is low, go out powder fineness always and do not reach requirement, go out powder fineness lack of homogeneity, return that powder fineness is little, lack of homogeneity, return powder amount (many qualified coal dusts cannot be separated) on the high side because of inferior separating effect, fineness of pulverized coal can not carry out the problems such as regular regulation along with Coal rank.In recent years, some manufacturing firms and scientific research department develop, have developed some novel mill separators, its performance makes moderate progress, but these novel mill separators still use traditional static separation technology, and the main adjustment manually being still dependent on angle of flap of the regulation of fineness of pulverized coal realizes.
Structure restriction due to the static blade that traditional coal pulverizer segregation apparatus exports at coal pulverizer, so aisle spare can only be controlled by the aperture adjusting folding rear blade, change fineness of pulverized coal, the most qualified coal dust is made repeatedly to grind in coal pulverizer, add interior circulating load, reduce separation efficiency.The inertia force simultaneously relying on coal dust carries out thickness separation, and separation efficiency is low, and fineness and uniformity are difficult to meet the requirement of boiler combustion high-efficiency environment friendly.
MPS-200 type medium-speed pulverizer, coal dust classifier is static separation device, and design fineness of pulverized coal is R90≤25%, and unevenness is up to 30%, and this fineness of pulverized coal can not meet the most far away the complete combustion needs of low NO.
Utility model content
For above-mentioned existing coal pulverizer segregation apparatus separation efficiency, low, fineness and uniformity are difficult to meet the problems such as the requirement of boiler combustion high-efficiency environment friendly, and this utility model provides a kind of sound Assembled rotary segregation apparatus.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of sound Assembled rotary segregation apparatus, including housing, stator blade, rotor, allotter and drive mechanism, stator blade, rotor and allotter are arranged in housing, rotor is by fixing the trunnion axis being connected with rotating shaft and the moving vane with Horizontal-shaft vertical forms, described stator blade and Horizontal-shaft vertical, and be arranged between moving vane and housing, stator blade is coaxial with moving vane, allotter is arranged on the top of rotor, and the top of allotter is provided with meal outlet, described drive mechanism is provided with frequency conversion motor, and rotor is driven by frequency conversion motor;
Described stator blade is for guiding shutter or static baffle plate.
The beneficial effects of the utility model:
The sound Assembled rotary segregation apparatus that this utility model provides, circulating ratio can be effectively reduced, it is possible to increase pulverizer capacity, owing to dynamic separator grinding efficiency is high, avoiding the grinding times again that fine particle is unnecessary, the most qualified coal dust can discharge coal pulverizer faster;Therefore, pulverizer capacity can be improved under identical ature of coal and fineness requirement;Or fineness of pulverized coal can be improved under identical ature of coal and requirement of exerting oneself;
Sound Assembled rotary separation energy is according to the change of coal-fired ature of coal, timely and conveniently adjust separator rotating speed so that fineness of pulverized coal to be adjusted, its range of accommodation is at R90=5% ~ 30%, the raising of fineness of pulverized coal reduces the mechanical incomplete combustion loss of boiler, be conducive to the utilization of colm, rotary separator separation efficiency is high, reduces and mills granule less than the mistake of 75 μm, thus improves exerting oneself and reducing the power consumption of pulverized coal preparation system of pulverized coal preparation system;
Rotary separator rotor blade than former static baffle plate life 50000 little time, save spare part expense, reduce maintenance labor intensity;The sound Assembled rotary segregation apparatus that this utility model provides, coal pulverizer fineness of pulverized coal can be adjusted with the change of coal-grinding machine-made egg-shaped or honey-comb coal briquets amount, unburned combustible in fly ash reduces about 3%, 6 overhaul lifes of rotary separator rotor blade life simultaneously, reduce the cost of repairs, raising equipment operational reliability, improves overall operation benefit and the profit of coal pulverizer.
Accompanying drawing explanation
Fig. 1 this utility model structural representation;
Reference: 1, housing, 2, stator blade, 3, rotor, 4, allotter, 5, meal outlet, 6, drive mechanism.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is further elaborated.
As shown in the figure: a kind of sound Assembled rotary segregation apparatus, including housing 1, stator blade 2, rotor 3, allotter 4 and drive mechanism 6, stator blade 2, rotor 3 and allotter 4 are arranged in housing 1, rotor 3 is by fixing the trunnion axis being connected with rotating shaft and the moving vane with Horizontal-shaft vertical forms, described stator blade 2 and Horizontal-shaft vertical, and be arranged between moving vane and housing 1, stator blade 2 is coaxial with moving vane, allotter 4 is arranged on the top of rotor 3, and the top of allotter 4 is provided with meal outlet, described drive mechanism 6 is provided with frequency conversion motor, rotor 3 is driven by frequency conversion motor;Described stator blade 2 is for guiding shutter.
