Drawings

Fig. 1 is a schematic structural diagram of a dust removing device according to an embodiment of the present invention.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the dust removal device comprises a dust removal tower 1, a sedimentation tank 2, a clean water tank 3 and a water inlet pipe 7, wherein the dust removal tower 1 is sequentially provided with a first filter layer 4, an overflow plate 5 and a second filter layer 9 from bottom to top.

The 1 lateral wall of gas wash tower is connected with air-supply line 11 of taking the fan, air-supply line 11 is located the below of first filter layer 4, and under the work of fan, the outer dusty gas of gas wash tower 1 can be sent into gas wash tower 1 inside through air-supply line 11 to rise along gas wash tower 1, after filtering the dust removal purification through first filter layer 4, overflow plate 5, second filter layer 9 in proper order, discharge to the atmosphere.

First filter layer 4 includes the multilayer filter screen, and the aperture of each layer filter screen reduces from supreme down gradually, can reach the multilayer filter effect.

Be formed with a plurality of even dense and vertically set up overflow pipe 6 on overflow plate 5, and 6 upper end openings of overflow pipe all in same horizontal plane, 7 one end of inlet tube extends to clean water basin 3, and the other end stretches into in dust removal tower 1, inlet tube 7 is located overflow plate 5's below to be connected with 5 bottom centers of overflow plate, can send into 5 tops of overflow plate with the clear water in clean water basin 3 through the water pump on inlet tube 7, when 5 water levels of overflow plate were higher than the overflow pipe, the clear water on overflow plate 5 just can be through 6 overflows of each overflow pipe and go out.

Wherein, still be connected with the drain pipe 8 of taking the valve on the overflow plate 5, outside 8 other ends of drain pipe extended to the gas wash tower 1, when out of work, open the valve on the drain pipe 8, can discharge the remaining clear water in 4 tops of overflow plate, be convenient for wash the maintenance.

Because be provided with many overflow pipes 6 on the overflow plate 5, and overflow pipe 6 is even intensive and arranges, consequently when clear water flows along each overflow pipe, can reach the effect that similar sprinkler head sprayed, thereby can reach the effect that sprays the dust removal, the clear water can spray on first filter layer 4 simultaneously, can drench first filter layer 4 completely, not only can realize effectively purifying dusty gas with first filter layer 4 cooperation, and realized rinsing to first filter layer 4 and washd and wash, improve life. Further, overflow plate 5 still separates dust removal tower 1 and is two-layer about, and gas can only be through overflow pipe 6 circulation that makes progress, and it can be in the overflow pipe further fully contact with the clear water to dust removal purifying effect has been improved greatly.

The second filter layer 9 is made of filter cotton and arranged above the inner part of the dust removal tower 1, and can absorb water vapor and residual fine particle dust, so that the filtering and dust removing effect is further improved.

1 bottom of gas wash tower is equipped with outlet pipe 12, outlet pipe 12 intercommunication sedimentation tank 2, the export intercommunication clean water basin 3 of sedimentation tank 2, the clear water on the overflow plate can contact with dirty gas after flowing down from the overflow pipe, and the dust is dissolved in after the water, just can send into sedimentation tank 2 through outlet pipe 12, and through the sedimentation tank sediment, the dust can deposit and stay at the sedimentation tank bottom of the pool, and the clear water then flows into the clean water basin, and the water in the clean water basin is sent into the overflow plate top once more through the inlet tube to realize cyclic utilization, resources are saved.

Above-mentioned dust collector during operation, the water pump can work, sends into the overflow board with the water in the clean water basin through the inlet tube on, when the water level on the overflow board exceeds the overflow pipe, the overflow pipe downward outflow can be followed to the clear water, and the water that flows down can drench first filter layer to drip downwards behind first filter layer.

Dusty gas enters into the gas wash tower inside back through the air-supply line, can rise along the gas wash tower, and at the in-process that dusty gas rises, partial dust can be directly taken away by the water absorption of drippage, then dusty gas enters into first filter layer, and at this moment, most dust granule can be blockked by first filter layer to dissolve in the aquatic of first filter layer and drip downwards, then send into through the outlet pipe and deposit in the sedimentation pond.

Gas after first filter layer filters can continue to rise, because be provided with many overflow pipes on the overflow plate, along the same formation of the water that each overflow pipe flows and spray the effect, it is before dripping first filter layer, also can form certain purifying effect to gas, and gas can just continue to rise through the overflow pipe simultaneously, and in the overflow pipe, gas can fully contact with the clear water, further improves purifying effect.

After the overflow pipe, gaseous can continue to rise through the second filter layer, and moisture and the remaining tiny granule in the gaseous at this moment can be absorbed by the second filter layer, through the filtration of second filter layer, guarantee through the gas drying and the no granule of fan, guarantee to reach emission standard, safety ring protects by the combustion gas.

According to the dust removal device, the overflow mode formed by the overflow plate and the overflow pipe is adopted to replace the spraying purpose of a conventional spraying head, so that the dust removal and purification effects are greatly improved.
