Abstract
The utility model discloses a fluidizing device which comprises a fluidizing device cavity connected with a coal feeding pipe, wherein a coal discharging pipe is arranged on the lower end of the fluidizing device cavity, the coal discharging pipe extends into the fluidizing device cavity, a ring-shaped filtering plate adapting to the coal discharging pipe and the fluidizing device cavity is arranged in the space between the outer wall of the coal discharging pipe and the inner wall of the fluidizing device cavity, and a gas feeding pipe is arranged on the fluidizing device cavity under the filtering plate. The fluidizing device of the utility model changes original point fluidizing modes into surface fluidizing modes, namely, the ring-shaped filtering plate is arranged in the fluidizing device, fluidized gas enters a hollow cavity under the filtering plate from the bottom of the fluidizing device cavity, and evenly acts on the filtering plate, thereby fully boiling coal powder above the filtering plate, the coal powder can be mixed with the gas evenly, and the fluidizing device further eliminates the phenomena that gas and coal mixing is not even, the coal feeding amount is little in the point fluidizing mode, thereby the coal power mixing is even, and the coal feeding amount is great.
Description
Technical field
The utility model relates to the fluidizer of winding-up jar in a kind of steel plant coal injection system, is a kind of device of fluidisation efficiently specifically.
Background technology
At present, the streaming mode that uses in steel plant's coal injection system is a fluidisation, promptly establishes 3～4 place's point fluidisation devices on the tapering of winding-up jar.Figure 1 shows that the streaming mode in existing winding-up jar tapering, it comprises winding-up jar tapering 11 and fluidisation device 12, the point streaming mode is that low-pressure gas enters the winding-up jar through several fluidisation devices 12 of winding-up jar tapering 11 annular spread, makes a winding-up jar interior coal dust be in fluidized state, and this helps coal smoothness down.But this mode is in real-world operation, owing to be that local several point has low-pressure air current to enter, so exist coal dust to mix uneven shortcoming, thus the following coal amount of coal dust also influenced.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of fluidisation device that improves coal dust mixture homogeneity and following coal amount is provided.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of fluidisation device, it comprises the fluidisation device cavity that links to each other with coal feeding pipe, coal output pipe is located at fluidisation device cavity lower end, and coal output pipe stretches in the fluidisation device cavity, space between the inwall of the outer wall of coal output pipe and fluidisation device cavity is provided with adaptive with it annular filter plate, is provided with air inlet pipe on the fluidisation device cavity below the screen plate.
Wherein, the outer wall of described coal output pipe is provided with annular boss, also is provided with annular boss with the annular boss corresponding position on the inwall of fluidisation device cavity; The inward flange of described screen plate and outward flange are respectively by being bolted on two boss.
Wherein, described screen plate is a corrosion-resistant steel sintering net, and filtering accuracy is 5 μ m.
Beneficial effect: a kind of fluidizer of the present utility model is improved to the surface current mode with original some streaming mode, promptly establish the annular filter plate in fluidisation device inside, fluidizing gas enters the screen plate lower cavity from the bottom of fluidisation device cavity, and stepless action is in screen plate, the coal dust of screen plate top is fully seethed with excitement, and coal dust and gas mix; And the bottle coal of having eliminated the some streaming mode mixes inhomogeneous, the following little phenomenon of coal amount, and coal dust is evenly mixed, the coal amount is big down.
Description of drawings
Fig. 1 is the structural representation of existing fluidisation device.
Fig. 2 is the integral structure scheme drawing of the utility model fluidisation device.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 2, a kind of fluidisation device of the present utility model comprises the fluidisation device cavity 1 that links to each other with coal feeding pipe, coal output pipe 2 is located at fluidisation device cavity 1 lower end, and coal output pipe 2 stretches in the fluidisation device cavity 1, space between the inwall of the outer wall of coal output pipe 2 and fluidisation device cavity 1 is provided with adaptive with it annular filter plate 3, is provided with air inlet pipe 4 on the fluidisation device cavity 1 below the screen plate 3.
The outer wall of described coal output pipe 2 is provided with a circle annular boss, also is provided with a circle annular boss with the annular boss corresponding position on the inwall of fluidisation device cavity 1; The inward flange of described screen plate 3 and outward flange are respectively by being bolted on two boss.Screen plate 3 is a corrosion-resistant steel sintering net, and filtering accuracy is 5 μ m.Low-pressure gas enters in fluidisation device cavity 1 lower cavity by air inlet pipe 4, and promptly in the space between screen plate 3 belows and the fluidisation device cavity 1, air-flow acts on screen plate 3; Thereby the coal dust that enters from screen plate 3 tops is fully seethed with excitement, be difficult for being attached on the screen plate 3, so that cause accumulation; And can make coal dust more even, flow out through coal unloading tube faster.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
