Description

Technical Field

[0001] This utility model relates to the field of yellow phosphorus tail gas technology, specifically a drainage device for a yellow phosphorus tail gas washing and conveying pipeline. Background Technology

[0002] Yellow phosphorus tail gas is the exhaust gas generated during the production of yellow phosphorus. It is mainly formed by the high-temperature reaction and incomplete combustion of raw materials. It contains harmful substances such as carbon monoxide, phosphine, and hydrogen sulfide, which pollute the atmospheric environment. Therefore, it is necessary to purify the yellow phosphorus tail gas. There are many types of processes for purifying yellow phosphorus tail gas in the existing technology, including washing treatment. After washing treatment, a large amount of wastewater will be generated. At this time, the wastewater needs to be further purified. A conveying pipeline drainage device is needed to discharge the wastewater between the two processes.

[0003] Existing wastewater discharge systems for conveying pipelines are inconvenient for storing wastewater during discharge. This leads to wastewater accumulation due to the different treatment efficiencies of the two processes, thus reducing wastewater treatment efficiency. Therefore, we propose a wastewater discharge system for yellow phosphorus tail gas scrubbing conveying pipelines. Utility Model Content

[0004] The purpose of this invention is to provide a drainage device for a yellow phosphorus tail gas scrubbing and conveying pipeline to solve the problems mentioned in the background art.

This avoids the situation where yellow phosphorus tail gas wastewater is easy to accumulate due to the different treatment efficiencies of different processes. During storage, the yellow phosphorus tail gas wastewater can be stirred to prevent the precipitation of residual impurities in the yellow phosphorus tail gas wastewater, which would affect the efficiency of further purification treatment.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: A drainage device for a yellow phosphorus tail gas scrubbing and conveying pipeline includes a drainage device housing 1. The drainage device housing 1 has an internal receiving groove 4. Two symmetrically distributed hinges 2 are fixedly connected to one side of the receiving groove 4. Inspection doors 3 are connected to the surfaces of the hinges 2 and are movably connected to the drainage device housing 1 via the hinges 2. A storage box 5 is fixedly connected to the inner wall of the receiving groove 4. A storage chamber 6 is formed inside the storage box 5. A drive motor 7 is fixedly connected to the top of the storage box 5. A drive shaft 8 is connected to the output shaft of the drive motor 7. The bottom of the drive shaft 8 extends into the storage chamber 6 and is fixedly connected to a stirring blade 9. A connecting groove 10 is formed on the surface of the storage box 5. A connecting pipe 11 is fixedly connected to the surface of the storage box 5 outside the connecting groove 10. The end of the connecting pipe 11 away from the storage box 5 penetrates the outer wall of the drainage device housing 1 and is fixedly connected to a connector 12.

[0027] The arrangement of the drainage device housing 1, hinge 2, inspection door 3, receiving tank 4, storage box 5, storage chamber 6, drive motor 7, drive shaft 8, and stirring blade 9 facilitates the storage of the washed yellow phosphorus tail gas wastewater before it enters the next stage of purification treatment. This avoids the situation where yellow phosphorus tail gas wastewater is prone to accumulation due to the different treatment efficiencies of different processes. Furthermore, the yellow phosphorus tail gas wastewater can be stirred during storage to prevent the precipitation of residual impurities in the yellow phosphorus tail gas wastewater, which would affect the efficiency of further purification treatment.

[0028] In this embodiment, there are two sets of connecting pipes 11 symmetrically distributed on both sides of the drainage device housing 1, and each set of connecting pipes 11 has several pipes at equal intervals, which facilitates connection with multiple washing towers and wastewater treatment equipment.

[0029] In this embodiment, the connecting pipe 11 is composed of a contraction section 1101, a throat 1102, and a diffusion section 1103. The throat 1102 penetrates the outer wall of the drainage device housing 1. The arrangement of the connecting channel 10, connecting pipe 11, contraction section 1101, throat 1102, and diffusion section 1103 helps to accelerate the efficiency of yellow phosphorus tail gas wastewater entering and exiting the storage chamber 6, thereby significantly improving the efficiency of secondary purification treatment.

[0030] In this embodiment, the contraction section 1101 is distributed in a conical structure, and the contraction section 1101 and the throat 1102 are an integrated structure. The diameter of the throat 1102 is equal to one-third to one-half the diameter of the contraction section 1101, which helps to accelerate the flow rate of wastewater.

[0031] In this embodiment, the throat 1102 and the diffuser section 1103 are an integrated structure, and the diffuser section 1103 is distributed in a conical structure with an inclination angle of 5-15°, which further accelerates the flow rate of wastewater.

[0032] In this embodiment, the stirring blades 9 form a rotating structure with the storage chamber 6 via the drive shaft 8, and several stirring blades 9 are evenly distributed on the surface of the drive shaft 8, which is beneficial for stirring the wastewater during storage and prevents the wastewater from settling, thus affecting the next step of purification treatment.

[0033] In this embodiment, the surface of the connector 12 is provided with a connecting through hole 13. Several connecting through holes 13 are distributed at equal angles along the axial center line of the connector 12. The connection 12 and the connecting through holes 13 facilitate the effective connection with the external pipe, thereby ensuring the storage and discharge of yellow phosphorus tail gas wastewater.

[0034] In this embodiment, the drainage device for the yellow phosphorus tail gas scrubbing and conveying pipeline first connects a set of connecting pipes 11 to the scrubbing tower via connecting parts 12 and connecting through holes 13. This allows the wastewater generated after the scrubbing tower treats the yellow phosphorus tail gas to flow into the storage chamber 6 through the connecting pipes 11 and connecting through holes 10. Then, another set of connecting pipes 11 connects to the wastewater treatment equipment via connecting parts 12 and connecting through holes 13. This allows the wastewater to be transported into the treatment equipment for further purification. During this process, the drive motor 7 is started, causing the drive motor 7 to drive the drive shaft 8 to rotate. The drive shaft 8 then drives the stirring blades 9 to rotate, causing the stirring blades 9 to stir the wastewater stored in the storage chamber 6. This effectively prevents the wastewater from settling during storage, which would affect the efficiency of the next purification process.

[0035] At the same time, when the wastewater flows inside the connecting pipe 11, it will contract when it enters the throat 1102 through the contraction section 1101 and diffuse when it enters the diffusion section 1103. This increases the flow velocity of the wastewater through the Venturi effect, thereby improving the efficiency of wastewater drainage.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
