Description
Technical Field
[0001] The utility model relates to the technical field of waste gas treatment, in particular to a Venturi swirl type waste gas spray tower. Background Art
[0002] The Venturi tower is a dust removal and washing equipment that uses the Venturi effect. The Venturi effect refers to the phenomenon that the flow velocity of the fluid increases when passing through a reduced flow cross-section. The flow velocity is inversely proportional to the flow cross-section. The Venturi tube refers to a pipe that first contracts and then gradually expands. The Venturi gas-liquid mixing method is used to aggregate particulate matter in the exhaust gas under pressure through "bonding", and large particles are formed from fine particles, which facilitates the separation of particulate matter in the exhaust gas.
[0003] The current Venturi tower is equipped with a water circulation structure to reduce the amount of water used in the device, but the current Venturi tower is not equipped with an automatic water replenishment structure.

[0030] See also Figure 1-6 The utility model provides a technical solution: a Venturi swirl exhaust gas spray tower, including a cylinder 1, a cone 2, a Venturi tube 3, an air inlet pipe 4, an air outlet pipe 5, a water storage tank 6, a circulating water pump 7, a water pipe 1 8, a sieve plate 9, an overflow pipe 10, a water supply tank 11, a float 12, a rack 13, a gear 14, a rack 2 15, a baffle 16, a water pipe 2 17, a spray rack 18, a partition 19, and a round tube 20.
[0031] This device has the effect of automatic water replenishment, specifically:
[0032] The cylinder 1 is a hollow structure, the lower end of the cylinder 1 is connected to the cone 2, the side surface of the cylinder 1 is provided with a venturi tube 3, the other end of the venturi tube 3 is connected to an air inlet pipe 4, the upper surface of the cylinder 1 is provided with an air outlet pipe 5, the outer surface of the cone 2 is provided with a water tank 6, and the lower end of the cone 2 penetrates the lower surface of the water tank 6, a circulating water pump 7 is provided on one side of the water tank 6, the circulating water pump 7 is fixed to the side surface of the water tank 6 through a bracket, one side of the circulating water pump 7 is connected to a water pipe 8, the other end of the water pipe 8 penetrates the surface of the venturi tube 3, and one side of the water tank 6 is provided with an automatic water replenishment structure, the automatic water replenishment structure uses the water replenishment tank 11 to automatically replenish the water tank 6 to prevent the circulating water pump 7 from When idling occurs, the automatic water replenishment structure includes a water replenishment tank 11, a water replenishment tank 11 is arranged on one side of the water storage tank 6, a water inlet is arranged on the surface of the water replenishment tank 11, a float 12 is arranged inside the water replenishment tank 11, a rack 13 is connected to the surface of the float 12, and the upper end of the rack 13 passes through the upper surface of the water replenishment tank 11, a gear 14 is rotatably arranged on the inner wall of the water replenishment tank 11, and one side of the gear 14 is meshed with the rack 13, a rack 2 15 is arranged on the other side of the gear 14, and the rack 2 15 is meshed with the gear 14, a baffle 16 is connected to one side of the rack 2 15, and the baffle 16 is slidably connected to the inner wall of the water replenishment tank 11, and the baffle 16 is aligned with the water inlet on the surface of the water replenishment tank 11;
[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the waste gas pipeline to be treated is connected to the upper end of the air inlet pipe 4, the external water pipe is connected to the water inlet on the surface of the water supply tank 11, and the circulating water pump 7 is started. The circulating water pump 7 drives the water in the water storage tank 6 to enter the venturi tube 3 from the water pipe 18, and the waste gas enters the venturi tube 3 from the air inlet pipe 4. Under the action of the venturi tube 3, the flow rate changes and is evenly mixed with the water mist in the water pipe 18, so that small particles in the waste gas gather to form large particles, so that the pollutants and the waste gas are better separated. The waste gas purified by the cylinder 1 is discharged from the air outlet pipe 5 at the upper end of the cylinder 1, and the water in the cylinder 1 is left along the inner wall of the cylinder 1.

When the water level rises, the float 12 rises, driving the rack 13 to rise, thereby driving the rack 2 15 and the baffle 16 to descend to block the water inlet again and stop water inlet.
[0034] This device has the effect of cyclone separation, specifically:
[0035] The cylinder 1 is provided with a swirl structure inside. The swirl structure uses the circular tube 20 to swirl the airflow entering the venturi tube 3, so that the pollutants in the exhaust gas can be separated more easily.
[0036] The swirl structure includes a circular tube 20, which is a cylindrical tube that penetrates from top to bottom. The circular tube 20 is installed on the lower surface of the partition 19, and the circular tube 20 is aligned with the outlet end of the venturi tube 3;
[0037] like Figure 1 and Figure 4 As shown, when the airflow enters the cylinder 1 from the venturi tube 3, the airflow impacts the outer wall of the circular tube 20. Under the action of the circular tube 20 and the inner wall of the cylinder 1, the airflow rotates in a spiral. Under the action of centrifugal force, the particles in the airflow are thrown to the inner wall of the cylinder 1, and slide down the cylinder 1 to the cone 2 for discharge, while the separated airflow rises along the cylinder 1 and is discharged.
[0038] This device has the effect of multi-layer spraying, specifically:
[0039] The inner wall of the cylinder 1 is provided with a partition 19, and a plurality of circular through holes are provided on the surface of the partition 19, and two of the partitions 19 are provided in parallel up and down. A spray structure is provided inside the cylinder 1, and the spray structure uses a spray rack 18 to perform secondary spraying on the exhaust gas to further remove pollutants in the exhaust gas. The spray structure includes a sieve plate 9, and the sieve plate 9 is provided on the outer surface of the cone 2. An overflow pipe 10 is provided on the surface of the water storage tank 6, and the height of the overflow pipe 10 is lower than the height of the sieve plate 9. The spray rack 18 is provided in an annular manner on the inner wall of the cylinder 1, and two of the spray racks 18 are provided in parallel. A water pipe 17 is provided on one side of the spray rack 18, and the other end of the water pipe 17 passes through the surface of the cylinder 1 and is connected to the water storage tank 6;
[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the airflow after cyclone separation rises and passes through the filler between the partitions 19. The airflow slowly rises in the filler. At this time, the spray rack 18 is started, and the spray rack 18 sprays the water drawn out from the water pipe 17 to spray the exhaust gas. The exhaust gas after spraying is discharged through the air outlet pipe 5 above, and the water after spraying flows along the inner wall of the cylinder 1 to the inner wall of the cone 2, passes through the sieve plate 9, and returns to the water storage tank 6 to complete the cycle.
[0041] Working principle: when using the Venturi swirl exhaust gas spray tower, a float 12 is set in the water supply tank 11 on one side of the water tank 6. As the water level moves, the float 12 moves to drive the rack 13 to move and drive the gear 14 to rotate. The rotation of the gear 14 drives the rack 2 15 to move. The rack 2 15 drives the baffle 16 to open the water inlet to automatically replenish the water tank 6. The airflow passes through the Venturi tube 3 and rotates in the cylinder 1 under the obstruction of the circular tube 20. The pollutants in the exhaust gas are separated from the airflow under the action of centrifugal force, and the particulate matter moves downward and is discharged. The airflow rises and passes through the filler between the partitions 19. The airflow passes evenly and slowly. The spray rack 18 sprays the exhaust gas evenly, further separates the pollutants in the exhaust gas, and increases the overall practicality.
