Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a desulfurization device with a wastewater treatment mechanism. Background Technology

[0002] With the rapid development of industry, especially in industries such as thermal power generation, steel smelting, and chemicals, a large amount of sulfur-containing waste gas is generated during combustion. If this sulfur-containing waste gas is directly emitted into the atmosphere, it will lead to the formation of acid rain, which will cause serious damage to soil, water bodies, buildings, and vegetation.

[0003] Announcement No. CN218795044U discloses a desulfurization device with a wastewater treatment mechanism, including a desulfurization tank, a slurry pump, a first motor, and a separation box. A water injection pipe is fixedly installed on the top of the desulfurization tank, and a liquid outlet pipe is fixedly installed on the bottom. A cover plate is rotatably installed on the upper part of the separation box. The first motor is fixedly installed at the bottom of the separation box, and its output end extends into the interior of the separation box and is fixedly connected to a positioning seat. A water filter box is engaged with the positioning seat. In this invention, after the device completes the desulfurization treatment of sulfur-containing waste gas, the user can drive the positioning seat to rotate via the first motor. This centrifugal force causes the waste liquid in the water filter box to flow to the periphery of the water filter box, thereby separating some impurities from the waste liquid. This facilitates further treatment and utilization of the waste liquid and slag by the user, making it highly practical.

[0004] However, the above-mentioned device has some drawbacks in actual use: the device pre-fills the desulfurization tank with water through the water injection pipe, and then adds reagents into the desulfurization tank through the reagent chamber. At the same time, the stirring column rotates with the stirring shaft, which causes the liquid in the desulfurization tank to mix with the reagents quickly. This means that a large amount of fresh water must be added to mix with the chemical reagents each time desulfurization is carried out, which will undoubtedly greatly increase the consumption of water resources. Although the device performs purification and separation of wastewater, it fails to effectively guide the purified wastewater for recycling. As a result, whenever a new desulfurization operation is started, the staff has to add fresh water again, which greatly increases the overall cost. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a desulfurization device with a wastewater treatment mechanism.

[0006] This utility model is achieved using the following technical solution: a desulfurization device with a wastewater treatment mechanism, comprising a recovery water tank, a desulfurization treatment tank fixedly connected to the upper surface of the recovery water tank, a purification tank fixedly connected to the upper surface of the recovery water tank, a drain hole provided in the inner bottom wall of the purification tank, holes adapted to the drain hole provided in the surface of the recovery water tank, a first conveying pump fixedly connected to the inner bottom wall of the recovery water tank, a guide pipe fixedly connected to the output end of the first conveying pump, a pipe frame fixedly connected to the outer surface of the guide pipe, and the top end of the guide pipe fixedly connected to the inside of the desulfurization treatment tank.

[0007] By using the above technical solutions, the recycling and reuse of wastewater reduces the water consumption when mixing chemical reagents in subsequent desulfurization operations, improves water resource utilization, and reduces operating costs.

[0008] As a further improvement to the above scheme, an air inlet pipe is fixedly connected to the outer surface of the desulfurization treatment tank, and a material discharge funnel is fixedly connected to the upper surface of the desulfurization treatment tank.

[0009] As a further improvement to the above solution, an exhaust pipe is fixedly connected to the upper surface of the desulfurization treatment tank, and a servo motor is fixedly connected to the upper surface of the desulfurization treatment tank.

[0010] Through the above technical solution, the exhaust pipe ensures the discharge path of the desulfurized gas, and the servo motor provides a power source for the subsequent stirring operation to improve the desulfurization effect.

[0011] As a further improvement to the above solution, the output end of the servo motor is fixedly connected to a stirring rod, which is located inside the desulfurization treatment tank.

[0012] Through the above technical solution, the stirring action of the stirring rod ensures the full mixing of chemical reagents and water, improves the desulfurization effect, and makes the desulfurization reaction more thorough.

[0013] As a further improvement to the above solution, a second delivery pump is fixedly connected to the upper surface of the purification tank, and a suction pipe is fixedly connected to the input end of the second delivery pump. The suction pipe is located inside the desulfurization treatment tank.

[0014] The above technical solution can effectively extract wastewater from the desulfurization tank for subsequent purification treatment.

[0015] As a further improvement to the above solution, a water delivery pipe is fixedly connected to the output end of the second delivery pump, and the bottom end of the water delivery pipe is located inside the purification box.

[0016] The above technical solution ensures that wastewater can be accurately transported from the desulfurization tank to the purification tank for purification treatment.

[0017] As a further improvement to the above solution, the purification box is equipped with a fine filter screen, the water supply pipe is located above the fine filter screen, and the drain hole is located below the fine filter screen.

[0018] Through the above technical solution, the fine filter array purifies the wastewater, improving the purification quality and making the water returned to the recycling tank purer.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention utilizes a second pump to draw wastewater generated during the desulfurization process into a purification tank for purification. The purified water then flows back to the recovery tank through a drain hole, and is subsequently pumped back to the desulfurization treatment tank by the first pump via a guide pipe. This circular system effectively recycles and reuses water resources, reducing the amount of additional water required to ensure the reaction proceeds. What would normally require a large amount of fresh water to ensure the dilution of chemical reagents and the reaction can now be met with only a small amount of fresh water due to the internal circulating water supply. This not only saves water resources but also reduces treatment costs to some extent. Attached Figure Description

A first delivery pump 5 is fixedly connected to the inner bottom wall of the recovery water tank 1, and a guide pipe 6 is fixedly connected to the output end of the first delivery pump 5. A pipe support 7 is fixedly connected to the outer surface of the guide pipe 6, and the top end of the guide pipe 6 is fixedly connected to the inside of the desulfurization treatment tank 2. Sulfur-containing gas enters the desulfurization treatment tank 2 for desulfurization. Wastewater is generated during the desulfurization process and is transported to the purification tank 3. The purification tank 3 purifies the wastewater, and the purified water flows back to the recovery water tank 1 through the drain hole 4. The first delivery pump 5 in the recovery water tank 1 transports the recovered water back to the desulfurization treatment tank 2 through the guide pipe 6. During this process, the pipe support 7 supports the guide pipe 6.

[0031] An air inlet pipe 8 is fixedly connected to the outer surface of the desulfurization treatment tank 2, and a feeding funnel 9 is fixedly connected to the upper surface of the desulfurization treatment tank 2. Sulfur-containing gas enters the desulfurization treatment tank 2 through the air inlet pipe 8, and at the same time, chemical reagents are added into the desulfurization treatment tank 2 through the feeding funnel 9 to provide the necessary material conditions for the desulfurization reaction.

[0032] An exhaust pipe 10 is fixedly connected to the upper surface of the desulfurization treatment tank 2, and a servo motor 11 is fixedly connected to the upper surface of the desulfurization treatment tank 2. After the gas in the desulfurization treatment tank 2 undergoes the desulfurization reaction, it is discharged to the outside through the exhaust pipe 10. The servo motor 11 is installed on the upper surface of the desulfurization treatment tank 2 to provide power for the internal stirring device.

[0033] The output end of the servo motor 11 is fixedly connected to a stirring rod 12, which is located inside the desulfurization tank 2. The stirring rod 12 at the output end of the servo motor 11 rotates inside the desulfurization tank 2, so that the chemical reagents and water are fully mixed, thereby enhancing the efficiency of the desulfurization reaction.

[0034] A second delivery pump 13 is fixedly connected to the upper surface of the purification tank 3. A suction pipe 14 is fixedly connected to the input end of the second delivery pump 13. The suction pipe 14 is located inside the desulfurization treatment tank 2. The second delivery pump 13 draws the desulfurized wastewater from inside the desulfurization treatment tank 2 through the suction pipe 14.

[0035] The output end of the second delivery pump 13 is fixedly connected to a water delivery pipe 15. The bottom end of the water delivery pipe 15 is located inside the purification tank 3. The second delivery pump 13 pumps the wastewater it draws into the purification tank 3 through the water delivery pipe 15, providing a channel for the wastewater to enter the purification tank 3.

[0036] The purification chamber 3 is equipped with a fine filter group 16. The water supply pipe 15 is located above the fine filter group 16, and the drain hole 4 is located below the fine filter group 16. After the wastewater enters the purification chamber 3 through the water supply pipe 15, it first passes above the fine filter group 16. After the filtration and other purification operations of the filter, the purified water flows out from the drain hole 4 located below the fine filter group 16.

[0037] The implementation principle of a desulfurization device with a wastewater treatment mechanism in this embodiment is as follows: Personnel open the valve of the inlet pipe 8, allowing sulfur-containing gas to enter the desulfurization treatment tank 2 through the inlet pipe 8. Chemical reagents and water are then added to the desulfurization treatment tank 2 through the feeding funnel 9, providing the necessary material conditions for the desulfurization reaction. Stirring is then started: the servo motor 11 is activated, and its output drives the stirring rod 12 to rotate inside the desulfurization treatment tank 2, ensuring thorough mixing of the chemical reagents and water and enhancing the efficiency of the desulfurization reaction. When the desulfurization reaction reaches a certain stage and wastewater is generated, the second delivery pump 13 is started. The second delivery pump 13 uses a suction pipe 14 to... Wastewater from desulfurization is drawn up from inside the desulfurization treatment tank 2. The second transfer pump 13 transports the drawn wastewater through the water supply pipe 15 to the purification tank 3. After entering the purification tank 3 through the water supply pipe 15, the wastewater first passes above the fine filter screen group 16 and is filtered by the filter screen. The purified water in the purification tank 3 flows back to the recovery water tank 1 through the drain hole 4. The first transfer pump 5 in the recovery water tank 1 is started. The first transfer pump 5 transports the recovered water back to the desulfurization treatment tank 2 through the guide pipe 6. During this process, the pipe frame 7 supports the guide pipe 6. After the gas in the desulfurization treatment tank 2 undergoes the desulfurization reaction, it is discharged to the outside through the exhaust pipe 10.
