Description
Technical field:
The invention belongs to the strength transportation art, particularly a kind of small-sized normal pressure Pulverized Coal Bin that has the fluidisation function.
Background technology:
Generally speaking, the breeze blowing system all be equipped with winding-up jar or small-sized in the middle of the powder storehouse, the coal supply operation when being used for the interim storage of coal dust and winding-up.The winding-up jar generally can bear higher pressure, and charges into high pressure gas when system's coal powder injection, and pressure is higher than the pressure in the coal feeder in the feasible winding-up jar, guarantees that coal dust can flow into coal feeder smoothly; Middle powder storehouse is generally as interim coal storage under the normal pressure and coal supply operation, for guaranteeing smooth and easy discharge coal dust, generally be the method that adopts mechanical agitation or the loosening coal seam of fluidisation plate, the adjusting of coal-supplying amount then can only be controlled by the variable frequency adjustment that increases the mechanical coal feeder device.This mode will certainly increase the consumption of power and the equipment input of system, is unreasonable and uneconomic to the injection system of miniaturization.
Summary of the invention:
The objective of the invention is to design a kind of small-sized normal pressure Pulverized Coal Bin that has the fluidisation function, adopt the mesolow air to carry out the loosening and local fluidization of coal dust layer, be convenient to the smooth eliminating of coal dust, match with the coal feeder of appropriate configuration simultaneously, be used for the adjusting of the amount of air realization system injecting coal quantity of local fluidization coal dust by change.
A kind of small-sized normal pressure Pulverized Coal Bin that has the fluidisation function, mainly constitute by coal dust feeding mouth 1, powder storehouse cylinder 4, powder storehouse cone 5, coal dust discharge orifice 9, it is characterized in that cone 5 places, powder storehouse have set up fluidisation cone 6, fluidizing gas pipeline 7, above coal dust discharge orifice 9, be provided with fluidisation ring 8, be used for the loosening and local fluidization of coal dust layer.Be provided with gas at coal dust feeding mouth 1 and diffuse mouth 2, the gas that is used for the loosening and local fluidization of coal dust layer can diffuse a mouthful discharge from gas.For the surplus of coal dust in coal dust amount in the weighing powder storehouse and the monitoring winding-up process storehouse, Pulverized Coal Bin the being provided with carriage 3 of weighing, the carriage of weighing is installed LOAD CELLS 3 times.
It is 0.2～0.8 times of powder storehouse cylinder diameter D that coal dust feeding mouth and gas diffuse between mouth apart from L, and the angle b of powder storehouse cone is about 40 °.The angle a of the fluidisation cone of establishing in the cone of powder storehouse is 90 °～120 °.Fluidisation cone upper surface is that wire gauze is welded, and cone base is cavity for connecting the metal sheet of tracheae in the fluidisation cone 6.Fluidisation cone and powder storehouse cone coaxial arrangement, installation site height H 1 are 0.2～0.5 times of cone height H, and the diameter D2 of fluidisation cone is 0.5～0.7 times of the diameter of section D1 of this place of powder storehouse cone.The diameter d 2 of fluidisation ring 8 is about 1.1 times of discharge diameter d, and cone lower surface, powder storehouse diameter d 1 is 0.90～0.95 times of the discharge diameter d, the distance h of cone lower surface, powder storehouse and discharge upper surface is-5～5mm, and fluidisation ring air inlet pipe is 15mm apart from cone lower surface, powder storehouse distance h 1.
Coal dust feeding mouth 1 is connected with controlled valve, the operation of packing into of control coal dust; Gas diffuses mouthfuls 2 and links to each other by the powder collector of pipeline with the breeze blowing system; Coal dust discharge orifice 9 is connected with ball valve, the coal supply operation during the control system coal powder injection; Fluidizing gas pipeline 7 links to each other with mesolow air or inert gas source with fluidisation ring 8, is used for the loosening and local fluidization of coal dust layer, is beneficial to the smooth discharge of coal dust.

The specific embodiment
Coal dust feeding mouth 1 is connected with controlled valve, the operation of packing into of control coal dust; Gas diffuses mouthfuls 2 and links to each other by the powder collector of pipeline with the breeze blowing system; Coal dust discharge orifice 9 is connected with ball valve, the coal supply operation during the control system coal powder injection; Fluidizing gas pipeline 7 links to each other with mesolow air or inert gas source with fluidisation ring 8, is used for the loosening and local fluidization of coal dust layer, is beneficial to the smooth discharge of coal dust.
Under loading coal powdery attitude, opening installation is at the valve on this top, powder storehouse, and from this coal dust container above powder storehouse coal dust of packing into, the gas in the Pulverized Coal Bin enters in the receipts powder device of system by pipeline by diffusing mouthfuls 2; Under system's coal injection state, at first in Pulverized Coal Bin fluidisation cone 6, feed mesolow air or unreactable gas, loosening coal dust layer; Open the valve that is connected in below the coal dust discharge orifice 9 then, the coal feeder to it under provides coal dust, feeds mesolow air or unreactable gas simultaneously in the fluidisation ring 8 of coal dust discharge orifice 9 tops, and the coal dust that local fluidization should be located is beneficial to the smooth discharge of coal dust; Weigh carriage 3 times of Pulverized Coal Bin is installed four LOAD CELLS, is used for the surplus of coal dust in the coal dust amount in weighing powder storehouse and the monitoring winding-up process storehouse; With condition that the coal supply device of appropriate configuration matches under, can be by changing the gas flow that feeds in the fluidisation ring 8, the coal powder blowing amount of control system.
