Abstract
The utility model discloses a powder fluidistor used in an industrial furnace powder fuel delivery system. The fluidistor comprises a machine body (1), a feed opening (2), a discharge opening (3) and an air inlet (4), wherein, the feed opening (2), the discharge opening (3) and the air inlet (4) are formed on the machine body (1); a fluidization plate (5) is arranged in the machine body (1) in such a manner that the fluidization plate (5) corresponds to the feed opening (2) so as to block the entire air inlet (4); and a plurality of small holes (6) are formed on the fluidization plate (5). The fluidization plate (5) provided by the utility model is used in the industrial furnace powder fuel delivery system, and has the advantages of good fluidization effect of gas and powder materials, uniform gas-ash mixture, simple structure, convenient manufacture and reliable performance.
Description
Technical field
The utility model relates to a kind of being used in the Industrial Stoves field, adopts the low pressure Pneumatic Conveying Technology to carry and jets pulverized fuel, in order to carry out the powder fluidisation device of mixing gasifying with low-pressure gas.
Background technology
In the Industrial Stoves field, utilize air-flow to carry in the powder material equipment, present employed gas ash mixing arrangement (powder fluidisation device), its structure is to form a vaporizer in the body, the body top is provided with material inlet, the middle part is provided with corresponding defeated material outlet, after powder material entered vaporizer from material inlet, the low-pressure gas that air inlet sprays into carried out mixing gasifying to powder material at vaporizer, and powder material is transferred out from defeated material outlet.The shortcoming that this gas ash mixing arrangement exists: because the fluidisation plate is not set in vaporizer, gas and mixing of materials are that nature forms, material can not form whole atomized flow entering conveyance conduit, might form rope form stream or bolt shape stream, if form the latter two logistics, to make a big impact to flow velocity in the conveyance conduit and pressure, in addition uncontrollable accurately to the length of flame in the kiln and temperature, have a strong impact on the result of use of conveying equipment.
The utility model content
Technical problem to be solved in the utility model provides a kind of gas and the powder material fluid effect is good, the powder fluidisation device that is used for Industrial Stoves pulverized fuel induction system that the gas ash mixes.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the powder fluidisation device that is used for Industrial Stoves pulverized fuel induction system, comprise body, be located at charging aperture, discharging opening and air inlet on the body, in described body, be provided with the fluidisation plate, described fluidisation plate is corresponding with described charging aperture and block whole air inlet, is provided with some apertures on described fluidisation plate.
Described fluidisation plate tiltedly is located in the described body, and its upper end contacts with described charging aperture, and its lower end is in described organism bottom and closes on the center line of described charging aperture.
Adopt the powder fluidisation device that is used for Industrial Stoves pulverized fuel induction system of technique scheme, pulverized fuel gets off from the charging aperture on the body, with the low-pressure gas of air inlet under the abundant gasification of fluidisation plate, the material gas mixture burns until burner hearth after discharging opening enters conveyance conduit.The fluidisation plate is the air inlet front on body, and tiltedly block whole air inlet, numerous aperture is arranged on the fluidisation plate, the low-pressure gas that air inlet is come in penetrates from the numerous aperture on the fluidisation plate, the low-pressure gas that air inlet is come in becomes the uniform gas curtain of shape that looses, contact the back with material and form uniform gas fogged stream, the gas ash thing that comes out from discharging opening very easily forms atomized flow, helping pulverized fuel greatly flows from the atomizing attitude that suspends in conveyance conduit, go out interruption-forming stabilized uniform flame at conveyance conduit terminal spray gun, thereby more can guarantee the constancy and the adjustability of pressure in the burner hearth and temperature.
In sum, the utility model is that a kind of gas and powder material fluid effect are good, and the gas ash mixes and the powder fluidisation device that is used for Industrial Stoves pulverized fuel induction system simple in structure, easily manufactured, dependable performance.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure vertical view;
Fig. 3 is the utility model structure right view.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2 and Fig. 3, body 1 is provided with charging aperture 2, discharging opening 3 and air inlet 4, in body 1, tiltedly be provided with fluidisation plate 5, its upper end contacts with described charging aperture 2, its lower end is in body 1 bottom and closes on the center line of charging aperture 2, fluidisation plate 5 blocks whole air inlet 4, is provided with some apertures 6 on fluidisation plate 5.
Referring to Fig. 1, Fig. 2 and Fig. 3, pulverized fuel from the charging aperture 2 on the body 1 get off and the low-pressure gas of air inlet 4 under the abundant gasification of fluidisation plate 5, the material gas mixture burns until burner hearth after discharging opening 3 enters conveyance conduit.Fluidisation plate 5 is air inlet 4 fronts on body 1, and tiltedly block whole air inlet 4, numerous aperture 6 is arranged on fluidisation plate 5, the low-pressure gas that air inlet 4 is come in penetrates from the numerous aperture 6 on the fluidisation plate 5, the low-pressure gas that air inlet 4 is come in becomes the uniform gas curtain of shape that looses, contact the back with material and form uniform gas fogged stream, the gas ash thing that comes out from discharging opening 3 very easily forms atomized flow, helping pulverized fuel greatly flows from the atomizing attitude that suspends in conveyance conduit, go out interruption-forming stabilized uniform flame at conveyance conduit terminal spray gun, thereby more can guarantee the constancy and the adjustability of pressure in the burner hearth and temperature.
Because fluidisation plate 5 tiltedly keeps off in air inlet 4 fronts, and form a slanted angle with air inlet 4, after the low-pressure gas that air inlet 4 is come in penetrates from the numerous aperture 6 on the fluidisation plate 5, to make low-pressure gas change direction, become little sideling direction towards the top, the little air-flow towards the top of this strand has stronger cleaning effect to the impeller that is installed in the powder flow controller on the charging aperture 2, the material of being convenient in the impeller lattice wheel is thoroughly drained clean, make the flow-control of powder flow controller more accurate, it is lighter to load, and prolongs the service life of powder flow controller.
