According to the device, the injection pipe is connected with compressed air, so that grains accumulating in the bottom discharging pipe are cleared when the discharging pipe is clogged during the operation; the characteristics of enabling powder to be conveyed more smoothly, preventing the pipeline being clogged and the like are realized; and the stability of pneumatic transmission can be greatly improved.
Description
Technical field
The utility model relates to a kind of Dual-Phrase Distribution of Gas olid feedway of material, relates in particular to a kind of winding-up pot bottom fluidizer.
Background technology
In commercial production, carry for the powder solid material being carried out continuous short distance, tend to make it become the fluidized solids with characteristic of fluid with falling the fluidised method of powder, with gas gas is carried then.In the existing desulfurizing iron injection system, when utilizing the mode conveying powder material of Dual-Phrase Distribution of Gas olid, usually in winding-up jar the employing fluidizer with desulfurization powder abundant fluidisation and sending in the Dual-Phrase Distribution of Gas olid pipeline.In order to increase solid-gas ratio, winding-up jar bottom is adopted up big and down small pyramidal structure usually, in its bottom fluid bed is set.Fluidizing gas upwards enters winding-up jar after by the fluid bed of bottom, makes the pulvis fluidisation in the winding-up jar, and the pulvis that is fluidized flows out from the discharging opening that is positioned at the winding-up pot bottom and enters the winding-up pipeline.In the winding-up jar working process, fluidizing gas upwards enters the winding-up jar, be folded to then with the discharging opening of pulvis from the streaming tank bottom and flow out, so fluidizing gas only has rheomorphism preferably to the pulvis of winding-up pot bottom, pulvis agitaion to winding-up jar top is poor, particularly, winding-up pot bottom tapering relatively poor when the powder stream dynamic characteristic of winding-up jar causes pulvis not fall into the bottom from winding-up jar top swimmingly easily when big, influences stability and continuity that pulvis is carried.For the stability that guarantees that pulvis is carried, the cone angle of jar conical section that must reduce to jet causes the height of whole winding-up jar to increase, for the layout of injection system is brought difficulty.
The utility model content
The purpose of this utility model is to provide a kind of can realize the stable winding-up pot bottom fluidizer of carrying of pulvis granule materials.
To achieve these goals, by the following technical solutions: a kind of winding-up pot bottom fluidizer, comprise housing, has the fluidized wind import on the housing, the fluidisation aerofoil that has taper in the housing, fluidisation aerofoil bottom links to each other with discharge nozzle, in the discharge nozzle of fluidisation aerofoil bottom the jet pipe coaxial with discharge nozzle is housed, described jet pipe top seal is provided with one or more nozzles in the jet pipe top-side.
Described nozzle distributes in the side equal angles.
The aperture of the nozzle of described jet pipe side is 1～3mm.
Carry fluidisation from a winding-up jar side fluidized wind import, at first enter winding-up tank shell and the formed fluidisation air compartment of fluidisation aerofoil, pressurized air enters supplies room by the fluidisation aerofoil then, under the mutual action of the pressed powder in supplies room and input gas, produce fluidized state, the material of supplies room fluidisation is under the effect of air-flow, constantly enter the discharge nozzle of winding-up pot bottom, material is transported in the pipeline by pipeline.When feed opening generation particle stopped up, the valve of opening on the jet pipe sprayed pressurized air from nozzle, and the pressure reduction that is centered around after the compressed air fluidisation of building up around the jet pipe of particle by winding-up jar and discharging opening pipeline drops down onto in the delivery duct.
The beneficial effects of the utility model are:
(1) the utility model has strengthened the agitaion of fluidizing gas to winding-up jar interior pulvis owing to adopted fluidisation jet pipe and fluidisation aerofoil to inflate simultaneously, is conducive to the fluidisation of pulvis.
(2) owing on the described fluidisation jet pipe nozzle is housed, strong to the agitation capability of pulvis, can solve discharging opening generation blocking problem, improve the stability of winding-up jar winding-up.
(3) because the utility model is strong to the agitation capability of pulvis, good stability, the winding-up amount of energy better controlled injection system.
In a word, the utility model can become the part of pulvis delivery system, by increasing winding-up pot bottom jet pipe, improves pulvis at the transportation performance of winding-up jar, optimizes the fluid effect of pulvis.Both be applicable to newly-built injection system, also be applicable to existing injection system.
Description of drawings
Fig. 1 is scheme drawing of the present utility model;
Scheme drawing when Fig. 2 uses for the utility model and winding-up jar combine.
Among the figure, 1 is that housing, 2 is that bottom bulkhead, 3 is that lower flange, 4 is that fluidisation aerofoil, 5 is that stay bearing plate, 6 is Circular Plate, and 7 is that fluidized wind import, 8 is that discharge nozzle, 9 is that jet pipe, 10 is the jet pipe nozzle, and 11 is valve, and 12 is valve, and 13 is differential pressure gauge.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing, but therefore the utility model is not limited in the concrete mode.
As illustrated in fig. 1 and 2, present embodiment comprises housing 1, fluidisation aerofoil 4, jet pipe 9, and wherein the fluidisation aerofoil is installed in the bottom of housing 1, is installed between Circular Plate 6 and the discharge nozzle 8, props up and forms the fluidisation air compartment with housing 1 through stay bearing plate 5.Be respectively equipped with valve 11 and valve 12 on fluidized wind import 7 and the jet pipe 9, and be provided with differential pressure gauge 13 between fluidized wind import 7 and the particle transport pipeline.
During the work of winding-up jar, pressure gas is by valve difference supply flow wind transmission plate 4 and jet pipe 9.The gas that enters winding-up jar by fluidisation aerofoil 4 mainly the be responsible for jet uniform particles fluidisation of pot bottom, with the mode of concentrated phase strength conveying carry pulvis through discharging opening to delivery duct; Check by observing differential pressure gauge 13 whether winding-up jar winding-up process is smooth and easy, when the discharge nozzle 8 generation dischargings of winding-up pot bottom are smooth, Open valve 12 makes pressurized air enter jet pipe to spray from nozzle, the pressurized air that enters jet pipe by jet pipe mainly is responsible for stirring the particle that is deposited in the discharging opening place, improves the conveying of spray in the winding-up jar.By evenly that winding-up pot bottom discharging opening outflow of particle of fluidisation, form a cover particle injection system.
The utility model can become the part of pulvis winding-up delivery system, by the agitaion improvement winding-up jar transportation performance to pulvis of fluidisation shower nozzle, optimizes the fluid effect of pulvis.The utility model is applicable to newly-built injection system, also is applicable to the transformation of existing injection system.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
