Description
Technical field
The present invention relates to a kind of coal dust and regulate separator, be particularly applicable to thermal power plant axial meal separator system.
Background technology
The coal dust that thermal power plant coal pulverizer grinds need to carry out sorting according to granularity, coarse granule is separated and returned to coal pulverizer, and being sent to boiler of feeding burning, the coal dust that meets fineness requirement uses, mill separator is exactly the key equipment of realizing this sorting, what now conventionally select is radial blade type or two kinds of structures of axial blade type, no matter axial-radial all needs to exist a secondary separation district, this district be realize separator separating effect critical component.
Summary of the invention
The present invention has developed a kind of coal dust and has regulated separator, its objective is provide a kind of simple and reasonable, wear-resisting durable, separative efficiency is high, coal dust is even, simple to operation, good work environment, safe and reliable coal dust regulate separator.
For achieving the above object, apparatus of the present invention are achieved through the following technical solutions, coal dust regulates separator, comprise adjusting footstalk, position pointer, stiff end fixture, steady brace, adjustable side fixture, outer cylinder body, middle cylinder body, inner barrel, help and revolve cone, controllable register, fixed dam, fixing lacing wire, regulate footstalk to be connected with adjustable side fixture, controllable register is connected with adjustable side fixture, controllable register is connected with stiff end fixture, adjustable side fixture is connected with outer cylinder body, stiff end fixture is connected with middle cylinder body, fixing lacing wire is connected with outer cylinder body, fixing lacing wire is connected with middle cylinder body, steady brace is connected with outer cylinder body, steady brace is connected with middle cylinder body, position pointer is connected with outer cylinder body, inner barrel with help revolve cone be connected, inner barrel is connected with fixed dam, middle cylinder body is connected with fixed dam, 36 of fixed dams are fixed on the subchannel inside of inner barrel and middle cylinder body formation with 40 ° of lift angles, help to revolve to bore and separate in secondary separation region aids with 50 ° of lift angles, 34 of controllable registers are evenly arranged between outer cylinder body and the main channel of middle cylinder body formation, by the adjusting to main channel fender plate, can effectively isolate the bulky grain coal dust through main channel, and can control from the swirl strength of effluent stream between subchannel fixed dam, isolate underproof coal dust, the coal dust of separating therefrom cylinder inboard wall fall time, can be again carried into centrifugation region by the ascending air of main channel again, make the wherein qualified fine silt of part be sent separator, " oneself cleans and separates " effect that coarse granule is separated again, thereby improve separative efficiency, improve the uniformity of outlet coal dust.
The invention has the beneficial effects as follows and utilize the modulability of controllable register to make wind powder mixture all can realize acceleration sorting in Disengagement zone in conjunction with the cone combination of different angles, make Whole Equipment possess efficient sorting feature.
