In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of circulation-type deduster, comprise deduster staving, deduster staving top is provided with gas vent, deduster staving bottom is provided with particle outlet, described deduster staving upper portion side wall front is provided with gas-solid fluid inlet, deduster inner wall of barrel is provided with to the inner baffle plate extending of this deduster staving, and on this baffle plate, attaching has arc-shaped partition, the annular flow-guiding channel that between arc-shaped partition and deduster inner wall of barrel, formation is communicated with gas-solid fluid inlet.
Upper side and the downside of the annular flow-guiding channel forming between described arc-shaped partition and deduster inner wall of barrel are respectively equipped with upper plate and lower shoe.
In described deduster staving, be equiped with straight tube, this straight tube upper end extends to deduster staving top, lower end extends to deduster bottom, and the two sides of this straight tube sidewall symmetry is respectively arranged with air inlet.
Air inlet on described straight tube is downward-sloping shape.
The rectangular shape of air inlet on described straight tube.
Described deduster staving sidewall front is provided with solid flow-guiding channel, and this solid flow-guiding channel upper end is communicated with gas-solid fluid inlet, lower end is communicated with deduster staving inner space.
Described gas-solid fluid inlet is horizontal.
Described gas-solid fluid inlet is downward-sloping shape.
The utlity model has three-stage filtration separation, and three grades of separating mechanisms all arrange in a staving, separated better dust removal effect, is used in conjunction with successful, long service life with fluidized bed coal gasification device.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model cross-sectional view;
Accompanying drawing 2 is the plan structure schematic diagram of this accompanying drawing 1;
Accompanying drawing 3 is the cross-sectional view of another embodiment of the utility model;
Accompanying drawing 4 is the structural representation of the utility model straight tube.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in accompanying drawing 1,2,3 and 4, the utility model has disclosed a kind of circulation-type deduster, comprise deduster staving 1, described deduster staving 1 upper portion side wall front is provided with gas-solid fluid inlet 3, deduster staving 1 top is provided with gas vent 5, deduster staving 1 bottom is provided with particle outlet 12, at deduster staving 1 inwall, be provided with to the inner baffle plate 10 extending of this deduster staving 1, on this baffle plate 10, attaching has arc-shaped partition 11, between arc-shaped partition 11 and deduster staving 1 inwall, forms annular flow-guiding channel 4.Upper side and the downside of annular flow-guiding channel 4 are respectively equipped with upper plate 6 and lower shoe 7, be that annular flow-guiding channel 4 has two ports, one of them port is communicated with gas-solid fluid inlet, another port is communicated with deduster staving inner space, and first the gas-solid mixture that makes to be entered by gas-solid fluid inlet enters in annular flow-guiding channel and rotate.In deduster staving 1 sidewall, be filled with high-abrasive material, make it not fragile.
In deduster staving 1, be equiped with straight tube 8, these straight tube 8 upper ends extend to deduster staving 1 top, lower end extends to deduster staving 1 bottom, the two sides of these straight tube 8 sidewall symmetries is respectively arranged with air inlet 9, and because being is symmetrical arranged, being equivalent to two angles between air inlet is 180 degree.Air inlet is downward-sloping setting, and two air inlets are all arranged to rectangular-shaped.Generally, on the two sides of straight tube 8 sidewall symmetries, an air inlet 9 is respectively set, but is not that the setting quantity of air inlet is limited herein, according to actual needs, air inlet can arrange three, and four, five, or other quantity.In addition, air inlet and the tangent setting of straight tube inwall, enter in straight tube gas more smoothly.The direction of rotation of the air inlet on the two sides of straight tube symmetry is identical, and the direction of rotation after gas enters in straight tube is consistent, makes can form bumpy flow in straight tube, effectively separation gas solid mixture.
In addition, gas-solid fluid inlet can be arranged to horizontal, is connected in a horizontal manner, as shown in Figure 1 with deduster staving.Or as shown in Figure 3, gas-solid fluid inlet is arranged to downward-sloping shape, angle of inclination need not be too large, is downward-slopingly a little connected with deduster staving.Deduster staving 1 sidewall front is provided with one-level solid flow-guiding channel 2, and these one-level solid flow-guiding channel 2 upper ends are communicated with gas-solid fluid inlet 3, lower end is communicated with deduster staving 1 inner space.
In the utility model, one-level solid flow-guiding channel is that one-level is separated, and the annular flow-guiding channel that baffle plate and arc-shaped partition form is the second-order separation, and the straight tube in deduster staving is three grades of separation, is all integrated in deduster staving compact conformation.The gas-solid mixture being entered by gas-solid fluid inlet, part mixture enters into deduster staving bottom through one-level solid flow-guiding channel, realizes one-level gas solid separation.Part mixture enters in annular flow-guiding channel, therefore because mixture has certain speed, in annular flow-guiding channel, be rotated, when mixture is when throwing away in deduster staving in annular flow-guiding channel, mixture is carried out to gas solid separation, realize the second-order separation.Enter in deduster staving containing the mixture of fine powder again the air inlet on straight tube enter into straight tube, by the downward rotary-cut of downward-sloping air inlet, enter, carry out three grades of separation, dedusting good separating effect.
