The specific embodiment
In the accompanying drawings, the efficient energy-saving deduster of this preventing gas flow short-circuit comprises the air inlet 1, I section accelerating cavity 2, I section sedimentation chamber 3, II section accelerating cavity 4, II section sedimentation chamber 5, water curtain dedusting chamber 10 and the exhaust outlet 14 that connect in turn; Be respectively equipped with six air channels in described I section accelerating cavity 2 and II section accelerating cavity 4; The bottom of I section sedimentation chamber 3 and II section sedimentation chamber 5 is respectively equipped with cinder-discharging port 6, and the cinder-discharging port 6 of described II section sedimentation chamber 5 doubles as the discharge outlet in water curtain dedusting chamber 10; Described water curtain dedusting chamber 10 is provided with water inlet 7, and described water inlet 7 places are provided with the cinder-discharging port 6 that a ramp extends to II section sedimentation chamber 5, and water tilts and lower and dust-contained airflow formation convection current from ramp by gravity; The choke block 13 that it is arc that described II section sedimentation chamber 5 has a top, it is parabola shaped deflector 11 that described water curtain dedusting chamber 10 is provided with a longitudinal section; Bottom that described choke block 13 is connected with deflector connects, and and the deduster bottom surface between leave restriction 8; Described restriction 8 places are provided with a flexible adjustment valve 9; The top in described water curtain dedusting chamber 10 is provided with water proof grid 12, and described exhaust outlet 14 places are equipped with air-introduced machine.
Described flexible adjustment valve 9 comprises a valve plate that is articulated in choke block 13 bottoms, and the upper end of described valve plate is connected with choke block 13 by spring.The effect of flexible adjustment valve 9 in the utility model is: when restriction 8 too small, or the air-introduced machine frequency is when excessive, can produce very large throttling intensity, after throttling intensity reached certain value, dusty gas made the 9 structure rotations of flexible adjustment valve to the percussion of this device, increases restriction 8, automatically reduce throttling intensity, prevent that the liquid layer in II section sedimentation chamber 5 from all being taken up by dust-contained airflow, cause dust-contained airflow directly by restriction 8, form short circuit phenomenon.
By finding out in accompanying drawing 1, I section accelerating cavity 2 horizontally sets, I section sedimentation chamber 3, II section accelerating cavity 4, II section sedimentation chamber 5 and water curtain dedusting chamber 10 all vertically settings, the bottom of described I section sedimentation chamber 3 and II section accelerating cavity 4 communicates, the top of described II section accelerating cavity 4 and II section sedimentation chamber 5 communicates, the gas outlet, top of the corresponding II section of the arc part of described choke block 13 sedimentation chamber 5.
Dust removal process of the present utility model is:
Dedusting for the first time: under the air-introduced machine effect at exhaust outlet 14 places, air inlet 1 place formation negative pressure, dust-contained airflow is inhaled into deduster, through I section accelerating cavity 2, air-flow enters I section sedimentation chamber 3, and because duct cross-section suddenly becomes greatly, the dust of large particle diameter deposits due to gravity and effect of inertia;
Dedusting for the second time: dust-contained airflow enters II section sedimentation chamber 5 through II section accelerating cavity 4, and large particle diameter dust continues sedimentation;
Dedusting for the third time: dust-contained airflow is at restriction 8 places impact liquid layer, and the dust of another particle size range is directly captured by liquid layer due to inertia in impact process;
The 4th dedusting: dust-contained airflow evokes a large amount of drops, rushes in water curtain dedusting chamber 10, forms the water curtain of parabolic, and drop continues dust is captured;
The 5th dedusting: dust-contained airflow can carry a part of drop through after water curtain, at water proof grid 12 places, because the air-flow streamline sharply changes, capture the drop of dust because effect of inertia collides on the grid page of water proof grid 12, the air-flow after dedusting is discharged from exhaust outlet 14.
