Description

Technical Field

[0001] This application relates to the field of dust removal technology, and in particular to a flue gas emission duct with a dust settling structure. Background Technology

[0002] In industrial production processes, flue gas emission ducts are common components of dust collection equipment, used to transport and treat dust-laden gases. However, existing flue gas emission ducts often suffer from incomplete separation of dust and moisture when handling dust-laden gases, leading to dust accumulation inside the duct and affecting dust collection efficiency and normal duct operation. Simultaneously, the settled impurities are difficult to effectively remove, requiring frequent cleaning and increasing maintenance costs and workload. Therefore, there is an urgent need for a flue gas emission duct that can effectively separate gas and water, settle impurities, and facilitate wastewater discharge. Utility Model Content

The sedimentation hole of the duct sedimentation tank is connected to the bottom of the side wall of the flue gas emission duct.

[0004] In one possible implementation, the pipeline sedimentation tank has a conical structure, and the cross-sectional area of ​​the pipeline sedimentation tank gradually decreases along the opening direction of the sedimentation holes.

[0005] In one possible implementation, the pipeline sedimentation tank is provided with a drain hole, which is located on the opposite side of the sedimentation hole.

[0006] One possible implementation also includes: a sewage tank; The sewage tank has a hollow box structure; The wastewater tank is located below the sedimentation tank in the pipeline and is connected to the drain hole.

[0010] In one possible implementation, the partition plate separates the pipeline sedimentation tank into a first sedimentation tank and a second sedimentation tank.

[0011] In one possible implementation, the partition plate extends toward the flue gas emission duct and is flush with the sedimentation hole.

[0012] In one possible implementation, the duct sedimentation tank is horizontally spaced at a predetermined distance from the port of the flue gas emission duct.

[0013] The beneficial effects of the flue gas emission pipe with dust settling structure in this application embodiment are as follows: through the cooperation of the gas-water separation chamber and the flue gas emission pipe, effective separation of gas and water is achieved, reducing the interference of water on dust settling.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0022] Figure 1 A schematic diagram of the main structure according to an embodiment of this application is shown. Figure 1 As shown, the flue gas emission pipe with a dust settling structure in this embodiment includes: a flue gas emission pipe 10 and a pipe settling box 30. The gas-water separation chamber 20 is a hollow structure, and the interior is suitable for installing a gas-water separation device. The flue gas emission pipe 10 is connected to the interior of the gas-water separator chamber, and the flue gas emission pipe 10 is inclined downwards. The pipe settling box 30 is a hollow structure and has a settling hole 31 at the bottom. The settling hole 31 of the pipe settling box 30 is connected to the bottom of the side wall of the flue gas emission pipe 10. The pipe settling box 30 is a square hollow structure and has a settling hole at the top. The settling hole is connected to the bottom of the side wall of the flue gas emission pipe 10.

[0023] In this specific embodiment, the effective separation of gas and water is achieved through the cooperation of the gas-water separation chamber 20 and the flue gas emission pipe 10, reducing the interference of water on dust sedimentation. The connection between the pipe sedimentation box 30 and the flue gas emission pipe 10 allows dust to settle smoothly into the pipe sedimentation box 30, avoiding dust accumulation in the flue gas emission pipe 10, improving dust removal efficiency. At the same time, the structure is simple and reasonable, and easy to manufacture and install.

[0024] The gas-water separation device can be a common centrifugal or filter type, used to separate gas and moisture in dust-laden gas, ensuring that the gas entering the subsequent flue gas emission duct 10 is relatively dry, reducing the impact of moisture on dust sedimentation and duct operation. Further details are omitted here. The flue gas emission duct 10 connects to the interior of the gas-water separation chamber 20, and is inclined downwards. This downward inclination facilitates stable gas and water flow, providing suitable space and flow field conditions for dust sedimentation. The duct sedimentation box 30 has a hollow structure with sedimentation holes 31 at the bottom. The sedimentation holes 31 of the duct sedimentation box 30 are connected to the bottom of the side wall of the flue gas emission duct 10. Heavier dust particles will settle under gravity and enter the duct sedimentation box 30 through the sedimentation holes 31 for sedimentation and collection.

[0025] In one specific embodiment, the pipe sedimentation tank 30 has a conical structure, and the cross-sectional area of ​​the pipe sedimentation tank 30 gradually decreases along the opening direction of the sedimentation holes 31. Utilizing the principle of gravity, the inverted conical structure of the pipe sedimentation tank 30 reduces the resistance encountered by dust particles during their descent as the cross-sectional area gradually decreases, allowing them to settle more quickly towards the sedimentation holes 31. Simultaneously, the conical structure makes the space at the bottom of the sedimentation tank relatively concentrated, facilitating dust collection and accumulation. In this specific embodiment, the conical structure of the pipe sedimentation box 30 enhances the dust sedimentation effect and improves the sedimentation efficiency, allowing more dust to quickly settle to the bottom of the sedimentation box, reducing the residence time of dust in the pipe sedimentation box 30, and further ensuring the smooth operation of the flue gas emission pipe 10.

[0026] In one specific embodiment, the pipeline sedimentation tank 30 is provided with a drain hole 32, which is located on the opposite side of the sedimentation hole 31. The drain hole 32 allows for the periodic discharge of settled dust and impurities, preventing the accumulation of impurities in the sedimentation tank, ensuring the continuous and effective operation of the pipeline sedimentation tank 30, and reducing the frequency and difficulty of manual cleaning.

[0027] In one specific embodiment, the system further includes a wastewater tank 40, which is a hollow box structure. The wastewater tank 40 is located below the pipe sedimentation tank 30 and connected to the drain hole 32. The wastewater tank 40 integrates the entire flue gas emission pipe 10 system into a complete sewage discharge and treatment system, facilitating unified management and disposal of wastewater and impurities, meeting environmental protection requirements, and improving the practicality and environmental friendliness of the equipment. In one specific embodiment, it also includes: a pipeline drain valve 33, which is installed on the drain hole 32 and can flexibly control the drain process according to actual needs. For example, when draining is required, the valve is opened to discharge the impurities in the sedimentation tank into the sewage tank 40, and the valve is closed during normal operation to prevent gas or dust from leaking from the drain hole 32. In this specific embodiment, the installation of the pipeline drain valve 33 facilitates the operator's control of the draining process, improves the convenience and flexibility of equipment use, and also ensures the sealing and stability of the system during operation.

[0028] In one specific embodiment, the inner wall of the pipeline settling tank 30 is a smooth plane. The smooth inner wall reduces dust residue, decreases the frequency of manual cleaning of the inner wall, improves the efficiency and convenience of the settling tank, and also helps to maintain the stability of the flow field inside the settling tank, promoting dust settling.

[0029] In one specific embodiment, the system further includes a partition plate 34. The partition plate 34 is a plate-shaped structure and is disposed inside the pipe sedimentation tank 30. The partition plate 34 is disposed on the inner wall of the pipe sedimentation tank 30 and is perpendicular to the inner wall of the pipe sedimentation tank 30. The partition plate 34 divides the internal space of the pipe sedimentation tank 30 into different areas, forming a multi-level sedimentation space. This allows dust particles to undergo sedimentation in multiple areas after entering the pipe sedimentation tank 30, enabling more thorough separation from the gas and improving the sedimentation effect. Among them, the partition plate 34 separates the sedimentation tank 30 into a first sedimentation tank and a second sedimentation tank.

[0030] In one specific embodiment, the partition plate 34 extends toward the flue gas emission pipe 10 and is flush with the sedimentation hole 31. This allows the dust particles to be better guided from the sedimentation hole 31 into the pipe sedimentation box 30. Under the action of the partition plate 34, the particles first enter the first sedimentation box and then the second sedimentation box, thus prolonging the time that the sludge liquid containing dust is in the pipe sedimentation box 30 and thereby improving the sedimentation effect. In one specific embodiment, the pipeline sedimentation tank 30 is positioned at a predetermined distance from the port of the flue gas emission pipe 10 in the horizontal direction to avoid mutual interference between the pipeline sedimentation tank 30 and the gas-water separation chamber 20.

[0031] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
