Abstract
A quickly loaded separation system for powdered coal ash is composed of electric flapper, draught fan, classifier, cyclon separator, cloth bag duster, fine ash hopper, coarse ash hopper, spiral conveyer for fine ash and screw conveyer for coarse ash. Its advantages include less possessed ground area and low cost.
Description
The present invention is a kind of quickly loaded separating system of powdered coal ash.
At present, the thermal power plant coal ash separation system generally has two kinds of open system and closed systems, former ash enters airflow separator through conveying pipeline by electronic flapper, cinder after the sorting flows into the cinder storehouse by the outlet of separator cinder, thin ash enters cyclone separator from the thin ash outlet of separator by pipeline, thin ash enters thin grey storehouse from the thin ash outlet of cyclone separator, cyclone separator is connected with electric cleaner by the road, ultra-fine ash is discharged from the outlet of electric cleaner, the pipeline of air-flow through being connected with electric cleaner enters blower fan, for open system, blast pipe directly enters atmosphere with tail gas, for closed system, backwind tube is sent tail gas back to primary air nozzle, wherein, also be connected to a secondary air channel that cinder is carried out secondary separation on separator, this secondary air channel inserts backwind tube and is communicated with backwind tube.The cinder storehouse of this type of separation system and thin grey storehouse are generally steel design, volume is all bigger, is generally the 100-300 ton, and the thin ash in the thin grey storehouse is after long storage time, thin ash is very easy to thin tide and hardens, long-time storage must be installed gasification installation or electric heating system additional, to send into hot gas to thin grey storehouse, solves the problem that the thin tide of thin ash hardens, system's floor space is big, conveyance conduit reaches 150 meters, and scale of investment is big, and utilization rate of equipment and installations is low.
The object of the present invention is to provide low, the reliable quickly loaded separating system of powdered coal ash of a kind of cost.
The present invention is achieved in that quickly loaded separating system of powdered coal ash comprises electronic flapper, air-introduced machine, grader, cyclone separator, at the charging aperture place electronic flapper is set, flyash enters grader by conveying pipeline, the air inlet pipe of air-introduced machine is communicated with conveying pipeline, the cinder outlet of grader is provided with electronic flapper, the thin ash of grader is sent into cyclone separator by the road, the thin ash outlet of cyclone separator is provided with electronic flapper, the outlet below of the electronic flapper of grader is provided with the cinder bucket, the cinder that comes out from the cinder bucket transports through the transmission of cinder conveying worm, the outlet below of the electronic flapper of cyclone separator is provided with thin ash bucket, send through thin grey conveying worm from the thin ash that thin ash bucket comes out, the air inlet pipeline of cyclone dust collectors connects air-introduced machine, the return line of the thin grey exhaust sack cleaner of setting up inserts the air inlet pipe of air-introduced machine, the outlet of exhaust sack cleaner inserts thin ash bucket, and is provided with electronic flapper in the exit.
The present invention is owing to change steel cinder storehouse and thin grey storehouse into cinder bucket and thin ash bucket, and cinder and thin ash are transported by conveying worm, floor space is little, cost is low, can produce at any time as required and instant transportation, because not in stock, the problem that does not exist thin ash to harden, and saved electric cleaner, shortened system's transfer pipeline, improved the service ability of equipment.
Below in conjunction with embodiment the present invention is described in detail:
Fig. 1 is coal ash separation system figure of the present invention.
Quickly loaded separating system of powdered coal ash comprises electronic flapper 2; 4; 9; air-introduced machine 1; grader 3; cyclone separator 8; electronic flapper 2 is set in the feed hopper exit; flyash enters grader 3 by conveying pipeline; the air inlet pipe of air-introduced machine 1 is communicated with conveying pipeline; the cinder outlet of grader 3 is provided with electronic flapper 4; the outlet below of this electronic flapper 4 is provided with cinder bucket 5; the cinder that comes out from cinder bucket 5 sends wet mixer 7 to through cinder conveying worm 6 and transports; the thin ash of grader 3 is sent into cyclone separator 8 by the road; the thin ash outlet of cyclone separator 8 is provided with electronic flapper 9; the outlet below of this electronic flapper 9 is provided with thin ash bucket 12; the volume of thin ash bucket 12 is the fully loaded volume of existing grey tank car; the volume of cinder bucket is 1/3rd of a thin ash bucket 12; the thin ash that comes out from thin ash bucket 12 is sent into dry type through thin grey conveying worm 13 and is unloaded stub bar 14; can directly adorn grey tank car transports; the air inlet pipeline of cyclone dust collectors 8 connects air-introduced machine 1; the return line of the thin grey exhaust sack cleaner of setting up 10 inserts the air inlet pipe of air-introduced machine 1; the outlet of exhaust sack cleaner 10 is provided with electronic flapper 11; the outlet of electronic flapper 11 inserts thin ash bucket 12; another sack cleaner 15 unloads stub bar 14 with dry type and cooperates operation; see on the whole; system's transfer pipeline only is about 45 meters; can make system equipment reach the operation designing requirement on the one hand; in addition because resistance is little; system energy consumption is low; reduced operating cost; system control office 16 adopts industrial procedure controller (PLC) control; after once debugging is finished; system can adopt single key stroke; after once adjustment is passed through; generally do not need again row to adjust; system stops transport can autostop; also can manual shut-down; that is to say; the operations staff is as long as aim at the outlet that dry type is unloaded stub bar 14 with grey tank car; truck is aimed at the outlet of wet mixer 7; then by a button; system just brings into operation; after grey tank car is filled; the level-sensing device that dry type is unloaded stub bar 14 will send the full signal of material, the operation of interrupt system automatically.
