The utility model is realized above-mentioned purpose through following technical scheme: a kind of screen collector; Be connected with dusting fan through dust removal pipe by dust absorption nozzle; Dusting fan is connected to the dedusting water tank through pipeline; The dedusting water tank is connected to discharge duct through pipeline, and the self-priming water circulating pump is connected to the spray head in the dedusting water tank through pipeline and water injector.
Be provided with baffle plate in the said dedusting water tank.
Said baffle plate is that alternatively up and down is installed S-shaped passage.
The operation principle of said screen collector is:
Screen collector adopts dust cleaning case as the main body purifying box, at self-priming water circulating pump, spray head; Make under the effect of turbulent flow drip washing and contain dusty gas and contact with baffle plate current and spray water mist fully; Make the weight of dust increase weight, dust is in water flows into the first deposition pond, again through the second sedimentation basin precipitation process; Flow to the 3rd sedimentation basin at last; The water of the 3rd sedimentation basin is evacuated to the water circulation in the dust cleaning case through self-priming centrifugal pump and recycles, and need not change water and only need moisturizing, and the gas after the processing can directly discharge.
Dedusting water tank internal structure and principle: inertia inertial dust collection
1, inertial dust collection mechanism:
Be provided with two baffle plates in the dedusting water tank, dust-contained airflow impacts on baffle plate, and air-flow and direction generation drastic shift by grit, make itself and flow separation.
2, wet dust collection technology, lector mechanism:
Behind self-priming centrifugal pump energising electricity, spray head can be sprayed water voluntarily in the dust cleaning case, the impact water surface downwards of turning after dusty gas is got into by air inlet behind the unlatching dusting fan, because section expansion is bigger, grit just leans on the gravity effect to fall in the water and is captured by water.The tiny grit that is not removed impacts the S shape passage that a large amount of water droplets of rolling get into two casing members along with gas carries, and air water fully contacts, and grit is that water droplet sticks.When S shape passage, because gas turns to suddenly, form centrifugal force, the grit that water droplet is sticked gets rid of to outer wall, and flows down along wall, thereby tiny grit is caught by water, and gas is purified.Gas gets into discharge duct after flowing out S shape passage, because the gravity effect, the tiny grit that water droplet and part are sticked for water returns in the water, and Purge gas is upwards flowed by the dust discharge pipeline, removes the fine liquid particles rear exhaust port once more through tall and big dust removing tube and discharges.The grit that is captured falls at the bottom of the sedimentation basin by deadweight.
