Abstract
The utility model provides a pulverized fuel ash on-line automatic magnetic separation device, which comprises an ash falling tube which is arranged on an electrical precipitator and is used for a thermal power plant boiler, wherein the ash falling pipe is a magnetic separation pipe, one side of the bottom end of the magnetic separation pipe is connected with an iron grains collector, the magnetic separation pipe comprises an inner and an outer layer cylinders, the wall of the inner cylinder is in a grid structure, the top end of the inner cylinder is provided with an umbrella-shaped hat, and the outer cylinder is sleeved with a ring-shaped electromagnet. The pulverized fuel ash on-line automatic magnetic separation device fully uses the working principle of a power plant electrostatic precipitator, fully uses the characteristics in an ash falling pipe that the moisture content of dry ash is small, the granularity is small and the fluidity is excellent, does not affect normal operation of a power plant boiler original ash conveying and discharging system, and achieving automation sorting collection.
Description
Technical field
The utility model relates to a kind of concentration equipment.
Background technology
Flyash is that coal dust burns the back from the flue discharge in coal-fired boiler in power plant, by the fine particle that deduster is collected, comprises SiO in its main chemical compositions
2, Al
2O
3, ferriferous oxide and other metal oxide and do not burn the carbon of cinder, wherein part irony component can be by the magnetic force sticking.In the flyash can be by magnetic force sticking composition mainly with Fe
2O
3, Fe
3O
4Exist with the form of ferrosilite, content is relevant with ature of coal, and is also relevant with the boiler type of furnace.
Recycle the iron in the flyash, generally adopt magnetic method.Magnetic separation process generally is divided into two kinds of dry method magnet choosing and wet magnetic separations.Magnetic plant commonly used comprises single roller dry-type magnetic extractor, permanent magnetism skeleton symbol magnetic separator, half counter-flow water magnetic cylinder formula magnetic separator etc.Facility is more, input is big, take up an area of deficiencies such as big, that environment is relatively poor, can not realize automatic sorting and separating effect is not good enough, dissemination is little but all exist.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes existing magnetic method, and a kind of device of online magnetic separation coal ash is provided, by the ferromagnetic material that contains in this device recycling flyash.
Structure of the present utility model is: it comprises the ash tube on the electric cleaner that thermal power plant boiler uses, and it is characterized in that described ash tube is the magnetic separation pipe, and one side is connected with the abrasive grit receptacle in the bottom of magnetic separation pipe; Described magnetic separation pipe is made of inside and outside two layered cylinder, and inner tube wall is a lattice structure, and the inner core top is provided with pileus, and the flyash that falls from electric dust collector is disperseed to urceolus; Urceolus is the urceolus of magnetic permeability material, is set with ring electromagnet on the urceolus.
This utility model fully combines the operation principle of electric dust collector, a work period of electric dust collector is divided into circulation timei and rapping time, form highfield between each battery lead plate in circulation timei, a large amount of grits in the flue gas are attracted on the pole plate, then by periodicity rapping pole plate, make bisque loosening, fall along ash tube.The magnetic separation pipe adopts calutron, work period is opposite with the electric precipitation work period, when the electric precipitation rapping falls ash, the magnetic field that this magnetic separation pipe racks electric forming intensity is adjustable, flyash is through the dispersion and the guide functions of interior pipe top end cap, by the tube of magnetic force, magnetic-particle wherein under the effect in magnetic field, by sticking on outer tube wall.When electric dust collector is in adsorption time, tube of magnetic force solenoid outage loss of excitation, the particle of sticking on outer tube fallen in the chute, along sliding to returnable under the chute.
Electromagnet in the utility model, the transformer that is carried by electric precipitation provides dc source, and increases regulating current device, the intensity of regulating magnetic field.Leak along the systematic pipeline transmission for the magnetic field that prevents the magnetic separation pipe, influence other electromagnetic equipments, take the soft iron mode of leading, magnetic separation pipe two ends are connected, act on position, magnetic separation pipe place with making magnetic separation pipe magnetic field TV university limit.
The utility model can realize that investment is little, simple to operate, magnetic separation process automatic blanking, automatic purpose of collecting, make full use of the operation principle of power plant's electrostatic precipitator, make full use of that the dry ash water capacity is little in the ash tube, granularity is little and the characteristics of good fluidity, and do not influence the normal operation that the former defeated row of boiler of power plant comes system, realize the automation separation and collection.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Among the figure: 1-pileus, 2-inner core, 3-urceolus, 4-ring electromagnet, 5-receptacle.
The specific embodiment
As shown in Figure 1, the utility model comprises the ash tube on the electric cleaner that thermal power plant boiler uses, and described ash tube is the magnetic separation pipe, and one side is connected with abrasive grit receptacle 5 in the bottom of magnetic separation pipe; Described magnetic separation pipe is made of inside and outside two layered cylinder, and inner core 2 walls are lattice structure, and the top is provided with pileus 1; Urceolus 3 is the magnetic permeability material, is set with ring electromagnet 4 above it.
