Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to dust removal equipment for a flue gas desulfurization tower. Background Art

[0002] The desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. The desulfurization tower was originally built with granite and was most widely used. It uses the principle of water film desulfurization and dust removal, and is also known as granite water film desulfurization dust collector, or granite water film desulfurization dust collector.

[0003] The flue gas in a traditional desulfurization tower usually flows directly upward, causing the flue gas to stay in the desulfurization tower for too short a time, resulting in insufficient reaction between the desulfurization liquid sprayed from the nozzle and the flue gas, resulting in poor flue gas desulfurization effect.

[0004] Therefore, we proposed a dust removal equipment for a flue gas desulfurization tower in order to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to solve the problem that the reaction effect between smoke and smoke removal solution is relatively poor.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dust removal device for a flue gas desulfurization tower, comprising a tower body, wherein a processing chamber and a liquid storage chamber are sequentially arranged inside the tower body from top to bottom, a cylinder is installed inside the processing chamber, a spiral sheet is installed on the outer surface of the cylinder, a water pump is installed inside the cylinder, a liquid suction pipe extending into the liquid storage chamber is installed at the water pumping end of the water pump, a spiral liquid spray pipe is installed at the water outlet end of the water pump, and a plurality of nozzles extending to the outside of the cylinder are installed on the outer surface of the liquid spray pipe.

[0007] Furthermore: a partition is arranged between the processing chamber and the liquid storage chamber, and a plurality of liquid flow holes are opened on the partition, and a plurality of liquid flow holes are located outside the cylinder.

[0008] Furthermore: a smoke inlet pipe communicating with the processing chamber is installed on the outer surface of the tower body, and one end of the smoke inlet pipe is fixedly connected to the outer surface of the tower body in a tangent form.

[0009] Furthermore: the outer surface of the tower body is also provided with a liquid inlet connected to the liquid storage chamber, and the liquid inlet is provided with a sealable sealing cover.

[0010] Furthermore: an exhaust port connected to the processing chamber is opened on the top of the tower body.

[0011] Furthermore: a liquid discharge port connected to the liquid storage chamber is installed at the bottom of the tower body, and a valve is installed on the liquid discharge port.

[0012] Beneficial effects of the utility model:

[0013] The utility model has spiral blades installed on the cylinder body, which play a role of blocking the flue gas, so that the flue gas in the treatment chamber can only flow upward in a spiral manner along the spiral blades, which can increase the residence time of the flue gas in the tower body, so that the desulfurization liquid sprayed by the nozzle can fully contact the flue gas, thereby improving the reaction effect between the flue gas and the desulfurization liquid, and improving the effect of flue gas desulfurization.

[0014] The utility model is provided with a plurality of air holes on the partition, and the desulfurization liquid sprayed from the nozzle can flow downward along the spiral sheet to the partition, and the desulfurization liquid on the partition can pass through the liquid flow holes and flow into the liquid storage chamber again for secondary utilization, thereby reducing the waste of desulfurization liquid.

[0021] Embodiments of the present utility model:

[0022] A dust removal device for a flue gas desulfurization tower comprises a tower body 1. A plurality of supporting legs 17 are fixed to the bottom of the tower body 1 at equal intervals in a circumferential direction. The supporting legs 17 are arranged to support the tower body 1. A partition 10 is fixed to the lower part of the tower body 1. The partition 10 divides the interior of the tower body 1 into a processing chamber 2 and a liquid storage chamber 3. The liquid storage chamber 3 is located at the lower part of the processing chamber 2. The flue gas can be desulfurized by the arrangement of the processing chamber 2. The desulfurization liquid can be stored by the arrangement of the liquid storage chamber 3. It should be noted that a desulfurizer is mixed with water to form a desulfurization liquid. A plurality of liquid flow holes 11 are provided on the partition 10. The desulfurization liquid after spraying can fall into the liquid storage chamber 3 again by the arrangement of the liquid flow holes 11. The desulfurization liquid can be used twice or multiple times, thereby reducing the waste of the desulfurization liquid.

[0023] A smoke inlet pipe 12 is fixed on the outer surface of the tower body 1 in a tangential manner, and the entrance end of the smoke inlet pipe 12 is connected to the interior of the processing chamber 2, so that after the smoke enters the processing chamber 2, it can flow along the inner wall of the tower body 1 to the position of the spiral sheet 5. An exhaust port 14 connected to the processing chamber 2 is fixed on the top of the tower body 1. Through the setting of the exhaust port 14, the treated smoke in the tower body 1 can be discharged.

[0024] A liquid inlet 13 is fixed at the lower part of the outer surface of the tower body 1, and one end of the liquid inlet 13 is connected to the interior of the liquid storage chamber 3. Through the setting of the liquid inlet 13, desulfurization liquid can be added to the liquid storage chamber 3. A liquid discharge port 15 is fixed at the center of the bottom of the tower body 1, and the top of the liquid discharge port 15 is connected to the liquid storage chamber 3. Through the setting of the liquid discharge port 15, the used desulfurization liquid in the liquid storage chamber 3 can be discharged. A valve 16 is installed on the liquid discharge port 15. Through the setting of the valve 16, the liquid discharge port 15 is closed or opened.

[0025] A cylinder 4 is fixed at the center of the top of the partition 10, and a water pump 6 is installed inside the cylinder 4. The water pump 6 is arranged to extract the desulfurized liquid. A liquid extraction pipe 7 is installed at the water extraction end of the water pump 6, and the bottom end of the liquid extraction pipe 7 passes through the partition 10 and extends to the lower part of the liquid storage chamber 3.

Several nozzles 9 are fixed at equal intervals on the outer surface of the liquid injection pipe 8, and the spraying end of the nozzle 9 extends to the outside of the cylinder 4 and is located inside the tower body 1.

[0026] When desulfurizing flue gas, first connect the external flue gas pipeline with the smoke inlet pipe 12, and the untreated flue gas enters the tower body 1 through the smoke inlet pipe 12. After the untreated flue gas enters the tower body 1, it can flow upward in a spiral manner along the spiral blade 5.

[0027] Then start the water pump 6, and the output end of the water pump 6 extracts the desulfurization liquid in the liquid storage chamber 3 through the liquid extraction pipe 7. The extracted desulfurization liquid enters the liquid spray pipe 8 through the water pump 6. The desulfurization liquid in the liquid spray pipe 8 is sprayed to the outside of the cylinder 4 and located inside the tower body 1 through a plurality of nozzles 9. The desulfurization liquid after spraying is fully in contact with the untreated flue gas, thereby generating a chemical reaction, and desulfurizing the untreated flue gas. The treated flue gas is discharged through the exhaust port 14, and the desulfurization liquid after spraying can flow downward along the spiral sheet 5 to the partition 10, so that the desulfurization liquid on the partition 10 flows again to the liquid storage chamber 3 through the liquid flow hole 11 for multiple utilization.
