Description of the drawings
Fig. 1 is overall structure diagram of the present utility model;
Wherein:
The upper cover of 1 gas outlet 2
The outer cylinder body of 3 air inlet 4
The sewage draining exit of 5 low head 6
7 baffles of inner conical-tube 8 times
The exhaustor of 9 inner barrel 10
Baffle in 11 overflow walls 12.
Specific embodiment
Hereinafter, with embodiment this utility model is described in detail referring to the drawings:
As shown in figure 1, a kind of gas-solid separating device, including outer cylinder body 4, the outer cylinder body 4 is internally provided with coaxial line
Inner barrel 9, the upper end of the outer cylinder body 4 is provided with the cone-shaped upper cover 2 connected with gas outlet 1, and lower end is provided with and sewage draining exit 6
The cone-shaped low head 5 of connection, the upper head plate center of the inner barrel 9 forms pilot hole, and lower end is provided with and is connected with sewage draining exit 6
Inner conical-tube 7, exhaustor 10 is provided with the pilot hole, be provided with baffle 12 at the inwall of the upper cover 2, it is described on
Baffle 12 forms No. I passage, the inner conical-tube 7 in addendum cone planar is gone between the side wall of upper baffle 12 and the inwall of exhaustor 10
Lower baffle 8 is provided with inwall, the lower baffle 8 is located under exhaustor 10 in band addendum cone planar, the vertex of a cone of lower baffle 8
Side, forms No. II passage between the side wall and the inwall of inner conical-tube 7 of lower baffle 8, the side wall of the inner barrel 9 is connected with air inlet 3,
The air inlet 3 passes through the side wall of outer cylinder body 4.
The upper end of the exhaustor 10 leans out the upper head plate of inner barrel 9, between the top of the inner barrel 9 and the outer wall of exhaustor 10
By the welded closure of overflow wall 11.
The upper end of the inner barrel 9 is welded seal with the connected mode of upper head plate.
The top edge of the air inlet 3 height is highly identical with the top seal of inner barrel 9.
The gas outlet 1, upper baffle 12, exhaustor 10, lower baffle 8, sewage draining exit 6 are coaxial.
Described upper baffle 12 is inversion state, that is, the lower end for going up baffle 12 is the vertex of a cone.
The upper end of described lower baffle 8 is the vertex of a cone.
This practical course of work is as follows:
The gas-solid mixture of industrial equipment discharge is tangentially entered in inner barrel 9 by air inlet 3, and gas-solid mixture is in inner barrel
Downwards, under the influence of centrifugal force, the larger granule of density to the wall of inner barrel 9 is moved 9 internal rotatings, and is caught at wall
Collection, because the effect of gravity is fallen along wall, by inner conical-tube 7, is discharged by sewage draining exit 6, realizes that granule is separated.
Unsegregated gas-solid mixture Jing inner barrels 9 are downward, into inner conical-tube 7, because the flowing space reduces, the radius of gyration
Reduce, gas-solid mixing fluid is rapidly turned round between inner conical-tube 7 and lower baffle 8, and streams reality from bottom to top along lower baffle 8
It is now reverse.Reversely fluid-mixing enters the spiral of exhaustor 10 upwards, and due to the effect of centrifugal force, solid particle is transported at wall
It is dynamic, in the exit of exhaustor 10, by the gap between upper baffle 12 and exhaustor 10, into inner barrel 9, outer cylinder body 4
Between, move downward under gravity, collect through low head 5, and discharged by sewage draining exit 6.
In the exit of exhaustor 10, most of gas carries the perforate that a small amount of solid particle enters upper baffle 12 secretly, leads to
Cross upper cover 2 and gas outlet 1 is discharged.
This utility model realizes the first separation of gas-solid mixing fluid by inner barrel inwall, inner conical-tube inwall, by interior
Cylinder, outer cylinder body realize the secondary separation of gas-solid mixing fluid, and this utility model can realize the high efficiency separation of solid particulate matter,
Purification gas.
