Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology and relates to a device for preventing liquid interruption in turbulent towers. Background Technology

[0002] The smelting process of sulfide ore generates high-concentration and low-concentration sulfur dioxide flue gas. The high-concentration sulfur dioxide flue gas is used for acid production, while the low-concentration sulfur dioxide flue gas is mainly desulfurized by reacting sulfur dioxide with various desulfurizing agents. Generally, the high-temperature flue gas first enters the turbulent jet tower for cooling and dust removal before entering the next process. If a liquid interruption occurs when the flue gas enters the turbulent jet tower for cooling and dust removal, the high-temperature flue gas will directly enter the tower body without cooling treatment, which will damage the tower body and affect the equipment and facilities of the next process.

[0006] Furthermore, a first infusion pump is installed on the first infusion tube.

[0007] Furthermore, an overflow pipe is connected to the upper part of the elevated water tank, and the overflow pipe is connected to the side wall of the reverse spray pipe.

[0008] Furthermore, a spray pipe is provided inside the turbulent jet tower body. The spray pipe is located at the upper part of the turbulent jet tower body. One end of the spray pipe extends out from the side wall of the turbulent jet tower body. Multiple nozzles are provided on the spray pipe along the length of the spray pipe.

The washing pipe is located above the spray pipe, with one end of the washing pipe extending out from the side wall of the turbulent jet tower body. Multiple second nozzles are provided on the washing pipe along its length.

[0011] The beneficial effects of this utility model are as follows: a high-level water tank is set above the turbulent flushing tower body. During washing, the washing liquid in the first liquid delivery pipe is transported to the high-level water tank for storage. When a liquid interruption occurs, the washing liquid stored in the high-level water tank is input to the reverse spray pipe to cool the flue gas in time. This can effectively prevent high-temperature flue gas from being transported into the turbulent flushing tower body and eliminate the impact of liquid interruption.

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings:

[0016] like Figure 1 and 2As shown, a liquid interruption prevention device for a turbulent flushing tower includes a turbulent flushing tower body 1. A reverse nozzle 2 for inputting flue gas into the tower body 1 is connected to one side of the tower body 1. A first liquid delivery pipe 3 is connected to the bottom of the tower body 1 and is connected to the side wall of the reverse nozzle 2. The first liquid delivery pipe 3 can deliver washing liquid to the reverse nozzle 2 to cool the flue gas inside the reverse nozzle 2. A first liquid delivery pump 4 is installed on the first liquid delivery pipe 3. A return liquid pipe 5 is connected to the middle of the first liquid delivery pipe 3. The return liquid pipe 5 is connected to a high-level water tank 6, which is located above the tower body 1. The first liquid delivery pump 4 can deliver the washing liquid at the bottom of the tower body 1 to the reverse nozzle 2 and the high-level water tank 6 through the first liquid delivery pipe 3 and the return liquid pipe 5, respectively. A replenishment pipe 7 is connected to the bottom of the high-level water tank 6 and is connected to the side wall of the reverse nozzle 2. In the event of a liquid interruption, the device can... The washing liquid stored in the high-level water tank 6 can be transported to the reverse spray pipe 2 through the replenishment pipe 7 to cool the flue gas in the reverse spray pipe 2. The replenishment pipe 7 is also equipped with a replenishment valve 8. In addition, an overflow pipe 9 is connected to the upper part of the side wall of the high-level water tank 6. The overflow pipe 9 is connected to the side wall of the reverse spray pipe 2. During use, when the liquid level in the high-level water tank 6 reaches the upper limit, it can be returned to the reverse spray pipe 2 through the overflow pipe 9 to prevent waste. The first liquid delivery pipe 3 is equipped with a pressure detection sensor 10 for detecting the hydraulic pressure in the first liquid delivery pipe 3. The pressure detection sensor 10 is connected to a controller 11. The controller 11 is connected to the replenishment valve 8. When a liquid interruption occurs, such as when the first liquid delivery pipe 3 is damaged or the first liquid delivery pump 4 fails, the pressure detection sensor 10 can detect the interruption and transmit the signal to the controller 11. The controller 11 then controls the replenishment valve 8 to open.

[0017] The turbulent flushing tower body 1 is equipped with a spray pipe 12 located on the upper part of the turbulent flushing tower body 1. One end of the spray pipe 12 extends through the side wall of the turbulent flushing tower body 1. Multiple first nozzles 13 are provided on the spray pipe 12 along its length. A second infusion pipe 14 is connected to the bottom of the turbulent flushing tower body 1. The second infusion pipe 14 is connected to the outer end of the spray pipe 12. A second infusion pump 15 is provided on the second infusion pipe 14. The washing liquid at the bottom of the turbulent flushing tower body 1 can be transported to the spray pipe 12 and sprayed out through the second infusion pump 15. A washing pipe 16 is provided inside the turbulent flushing tower body 1. The washing pipe 16 is located above the spray pipe 12. One end of the washing pipe 16 extends through the side wall of the turbulent flushing tower body 1 and is connected to a water source. Multiple second nozzles 17 are provided on the washing pipe 16 along its length.

[0018] The method of using this utility model is as follows:

[0019] During sulfur dioxide flue gas treatment, the sulfur dioxide flue gas is input into the turbulent flushing tower body 1 through the reverse nozzle 2. The first liquid pump 4 is started to transport the washing liquid in the turbulent flushing tower body 1 to the reverse nozzle 2 through the first liquid pipe 3, cooling the sulfur dioxide flue gas in the reverse nozzle 2. At the same time, the washing liquid in the first liquid pipe 3 can also be transported to the high-level water tank 6 through the return liquid pipe 5 for storage. When the liquid level in the high-level water tank 6 reaches the upper limit, it can overflow into the reverse nozzle 2 through the overflow pipe 9 to prevent the washing liquid from overflowing and being wasted. Simultaneously, the second liquid pump 15 is started, and the washing liquid in the turbulent flushing tower body 1 is transported to the spray pipe 12 through the second liquid pipe 14 and sprayed out through the first nozzle 13 to spray the flue gas in the turbulent flushing tower body 1. Simultaneously, the washing pipe 16 sprays water through the second nozzle 17 to wash the flue gas. During operation, if the first liquid supply pipe 3 is damaged or the first liquid supply pump 4 malfunctions, causing a liquid interruption, and the first liquid supply pipe 3 cannot deliver washing liquid to the reverse spray pipe 2 to cool the sulfur dioxide flue gas, the pressure detection sensor 10 detects an abnormality in the hydraulic pressure in the first liquid supply pipe 3 and sends a signal to the controller 11. The controller 11 controls the liquid replenishment valve 8 to open, and the washing liquid stored in the high-level water tank 6 flows into the reverse spray pipe 2 through the liquid replenishment pipe 7 to cool the flue gas in the reverse spray pipe 2. This can effectively prevent the flue gas in the reverse spray pipe 2 from being unable to be cooled when a liquid interruption occurs, causing the high-temperature flue gas to directly enter the turbulent jet tower body 1 and damage the turbulent jet tower body 1.
