Reciprocating plate water film desulfurization dust collector

technical field

The utility model relates to a desulfurization dust remover, in particular to a reciprocating plate type water film desulfurization dust remover.

Background technique

Common flue gas desulfurization and dust removal devices for coal-fired boilers include spray type, Venturi tube type, impact purification type, etc. In order to improve the dust removal efficiency, people usually use them in series, or modify them, but often make the floor area or production The cost is greatly increased. This is not conducive to production, nor can it coordinate and maintain various desulfurization and dust collector equipment well. In actual production, the shutdown rate is very high, and the actual promotion and application value of this type of equipment is not great.

Fig. 1 is the structural representation of the utility model.

In the figure, 1. Air inlet 2. Impact mixing and purification pipeline 3. Reciprocating plate 4. Partition plate 5. Spray dust removal chamber 6. Dehydration chamber 7. Air outlet 8. Mud cleaning cover 9. Water level control gate valve 10. Liquid port 11, sprinkler head 12, ash sink.

Detailed ways

As shown in Figure 1, the utility model is realized in this way, it comprises air inlet 1, impact mixing purification pipe 2, reciprocating plate 3, dividing plate 4, spray dedusting chamber 5, dehydration chamber 6, air outlet 7, The mud cleaning cover 8, the water level control gate valve 9, the liquid inlet 10, the spray head 11 and the ash settling tank 12 are characterized in that the top of the impact mixing purification pipeline 2 is connected with the air inlet 1 and the liquid inlet 10, and the impact mixing The inner wall of the purification pipeline 2 is connected with a number of inclined downward reciprocating plates 3, the bottom of the impact mixing purification pipeline 2 is connected with the bottom of the spray dust removal chamber 5, and the top of the spray dust removal chamber 5 is connected with a spray head 11. The side wall of the spray dust removal chamber 5 located below the shower head 11 is provided with several staggered partitions 4 inclined downward. The upper part of the spray dust removal chamber 5 communicates with the upper part of the dehydration chamber 6, and the dehydration chamber 6 The lower part of the tank is provided with an air outlet 7, and just below the impact mixing and purification pipeline 2 and the spray dedusting chamber 5 is an ash sink 12, the side of which is connected with a water level control gate valve 9, and the top of the ash sink 12 is also connected with a cleaning Mud cover8.

The implementation and working principle of the present utility model are such that water and gas enter from the air inlet 1 and the liquid inlet 10 respectively, and enter the impact mixing and purification pipeline 2 together at a high speed, which is better than the effect of the reciprocating plate 3, so that the gas and water are parallel Adequate exposure is conducive to the absorption of dust and sulfur dioxide. Impact the ash sink 12 water surfaces again, then enter the spray dedusting chamber 5 from below. After reverse spraying by the shower head 11 , the gas enters the dehydration chamber 6 from above the spray dedusting chamber 5 and is discharged from the gas outlet 7 . Among them, impacting mixed purification pipeline: the gas and liquid impact the reciprocating plate 3 on the left at 45 degrees from directly above, and rebound to the reciprocating plate 3 on the right. In this way, the gas changes direction rapidly, and the dust collides with the inclined plate with dust removal liquid and is absorbed. Sulfur dioxide is also absorbed by the liquid gas. The pipeline should not be too thick, depending on the gas flow rate; spray area: the liquid is sprayed from above and passes through the partition 4 to form a water film. The gas is fully in contact with the water film from bottom to top to remove impurities.
