Description

Technical Field

[0001] This utility model relates to the technical field of advanced desulfurization wastewater treatment devices, specifically, to an environmentally friendly advanced desulfurization wastewater treatment device. Background Technology

[0002] Desulfurization wastewater refers to the wastewater generated during the flue gas desulfurization process. It generally comes from wet desulfurization processes and is wastewater containing a large number of impurities discharged from the bottom of the desulfurization absorption tower. Its composition is complex, containing a large amount of floating matter, heavy metals, sulfates, and small amounts of fluorides and chlorides. It is characterized by turbidity and acidity. If it is discharged directly without treatment, it will cause serious pollution to the surrounding environment and disrupt the ecological balance. Therefore, it is necessary to use advanced treatment devices to treat desulfurization wastewater.

[0003] When treating desulfurization wastewater, advanced treatment devices typically add alkaline substances such as lime and sodium hydroxide to the storage tank to adjust the pH value of the wastewater to a suitable range. This causes heavy metal ions in the wastewater, such as copper and zinc, to form hydroxide precipitates, thereby achieving a purification effect.

[0004] Traditional desulfurization wastewater deep treatment devices typically add a certain amount of powder, such as lime and sodium hydroxide, directly into the wastewater when adding it to the storage tank. When a large amount of lime powder is added, the remaining lime powder is likely to remain in the wastewater, resulting in significant material loss and increased alkalinity of the wastewater. Subsequently, the discharged wastewater can easily damage the surrounding environment and thus affect the ecological environment. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly deep treatment device for desulfurization wastewater, which solves the problem that existing deep treatment devices for desulfurization wastewater are inconvenient to quantitatively add lime powder, which easily leads to excessive lime powder addition, causing the wastewater to become alkaline, thereby increasing treatment costs and damaging the surrounding environment, which is not conducive to environmental protection.

[0006] This utility model provides the following technical solution: an environmentally friendly desulfurization wastewater deep treatment device, including a water storage tank, an inlet fixedly connected to one end of the water storage tank, and a control box fixedly connected to the outer side of the end of the water storage tank near the inlet.

[0012] As a preferred embodiment of the above technical solution, the lower end of the discharge pipe is rotatably connected to a rotating drum, and a storage trough is provided inside the upper end of the rotating drum.

[0013] The above technical solution allows the falling lime powder to enter the storage tank by rotating the drum.

[0014] As a preferred embodiment of the above technical solution, one end of the rotating drum is fixedly connected to a second motor, which is part of the power structure, through the output shaft and the guide cylinder. The end of the second motor away from the guide cylinder is fixedly connected to a fixing plate, and the lower end of the fixing plate is fixedly connected to the water storage tank.

[0016] As a preferred embodiment of the above technical solution, a plate is inserted inside the drain outlet, and a filter screen is fixedly connected to the middle of the plate, while a handle is fixedly connected to the upper end of the plate.

[0017] With the above technical solution, the insert plate and filter screen can be pulled out of the drain outlet for cleaning by pulling the handle.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 - Figure 5As shown, this utility model provides a technical solution: an environmentally friendly desulfurization wastewater deep treatment device, including a water storage tank 1, an inlet 11 fixedly connected to one end of the water storage tank 1, and a control box 12 fixedly connected to the outer side of the end of the water storage tank 1 near the inlet 11. A first cabinet door 13 is provided below the control box 12 and is rotatably connected to the water storage tank 1. A feeding assembly 2 is provided at the upper end of the water storage tank 1, and the feeding assembly 2 includes a storage box 21 provided at the upper end of the water storage tank 1. A support rod is fixedly connected to the lower outer end of the storage box 21. 22, and a feed inlet 23 is fixedly connected to one end of the upper side of the storage tank 21, a guide plate 24 is fixedly connected to the lower end of the water storage tank 1, and an anti-clogging structure 3 is provided in the middle of the upper side of the storage tank 21, a feeding structure 4 is provided in the middle of the lower side of the water storage tank 1, and a power structure 5 is provided on one side of the feeding structure 4. The lime powder can be quantitatively fed through the feeding component 2, thereby reducing the material loss caused by excessive feeding, improving the purification effect of wastewater, balancing the acidity and alkalinity of wastewater, and reducing the damage to the surrounding environment caused by subsequent discharge of wastewater.

[0029] like Figure 3 As shown, the anti-blocking structure 3 includes a first motor 25 fixedly connected to the middle of the upper side of the storage box 21, and a rotating rod 26 fixedly connected to the output shaft of the first motor 25 through the storage box 21. A threaded rod 27 is fixedly connected to the lower end of the rotating rod 26. After the first motor 25 is turned, the output shaft drives the rotating rod 26 and the threaded rod 27 to rotate, so that the threaded rod 27 stirs the lime powder at the upper end of the discharge pipe 28, causing it to fall quickly.

[0030] like Figure 3 As shown, the feeding structure 4 includes a discharge pipe 28 fixedly connected to the middle of the lower side of the storage box 21, and a guide tube 29 is sleeved on the outer side of the lower end of the discharge pipe 28. The lower end of the guide tube 29 is fixedly connected to the water storage tank 1. The discharge pipe 28 and the guide tube 29 guide the falling lime powder.

[0031] like Figure 3 As shown, a rotating drum 210 is rotatably connected to the lower end of the discharge pipe 28, and a storage trough 211 is provided inside the upper end of the rotating drum 210. When the rotating drum 210 drives the storage box 21 to rotate to the upper end, the falling lime powder enters the storage trough 211 for storage. When the rotating drum 210 drives the storage trough 211 to rotate to the lower end, the rotating drum 210 blocks the discharge pipe 28, and the lime powder in the storage trough 211 falls into the water storage tank 1.

[0032] like Figure 1 and Figure 4As shown, one end of the rotating drum 210 is fixedly connected to the second motor 212 of the power structure 5 through the output shaft through the guide tube 29, and the end of the second motor 212 away from the guide tube 29 is fixedly connected to the fixing plate 213. The lower end of the fixing plate 213 is fixedly connected to the water storage tank 1. The second motor 212 operates under the support of the fixing plate 213, thereby driving the rotating drum 210 and the storage tank 211 to rotate.

[0033] like Figure 2 As shown, a separation component 6 is provided at the end of the water storage tank 1 away from the water inlet 11, and the separation component 6 includes a drain outlet 31 fixedly connected to the end of the water storage tank 1 away from the water inlet 11. A second cabinet door 32 is rotatably connected to the end of the drain outlet 31 away from the water storage tank 1. The treated wastewater can be discharged by opening the second cabinet door 32.

[0034] like Figure 5 As shown, a plate 33 is inserted inside the drain outlet 31, and a filter screen 34 is fixedly connected to the middle of the plate 33. A handle 35 is fixedly connected to the upper end of the plate 33. The filter screen 34 filters the wastewater and the precipitated heavy metals. Afterwards, the handle 35 can be pulled to pull the plate 33 and the filter screen 34 out of the drain outlet 31 for cleaning.

[0035] Working principle: When performing deep treatment of desulfurization wastewater, the wastewater to be treated is first injected into the storage tank 1 through the inlet 11. Then, the first motor 25 and the second motor 212 are started according to the requirements. After the first motor 25 starts, the output shaft drives the rotating rod 26 and the threaded rod 27 to rotate, so that the lime powder in the storage tank 21 is guided by the guide plate 24 and collected at the discharge pipe 28 for dropping. After the second motor 212 starts, the output shaft drives the rotating drum 210 and the storage tank 211 to rotate. When the upper end of the storage tank 211 is on the same plane as the discharge pipe 28, the lime powder in the storage tank 21 enters the storage tank 211 through the discharge pipe 28 for storage. Subsequently, the rotating drum 210 continues to rotate. When the storage tank 211 rotates to the lower end, the rotating drum 210 discharges the lime powder at the discharge pipe 28. The lime powder in the storage tank 211 is blocked, and it falls into the water storage tank 1 through the guide tube 29 to mix with the desulfurization wastewater, thereby causing the heavy metals in the wastewater to precipitate. The precipitated heavy metals are deposited at the bottom of the water storage tank 1. Then the second cabinet door 32 can be opened to discharge the treated desulfurization wastewater inside the water storage tank 1, while the precipitated heavy metals are blocked by the filter screen 34 and remain in the water storage tank 1. Later, the first cabinet door 13 can be opened to clean out the deposited heavy metals. Alternatively, the insert plate 33 and filter screen 34 can be pulled out of the drain outlet 31 by pulling the handle 35 to clean the filter screen 34. After cleaning, the insert plate 33 and filter screen 34 can be inserted into the drain outlet 31 by using the handle 35. When the lime powder in the storage tank 21 is insufficient, lime powder is injected into the storage tank 21 through the feed port 23 for storage.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
