Description

Technical Field

[0001] This utility model relates to the field of negative electrode material production technology, and in particular to a spray purification tank. Background Technology

[0002] During the production of anode materials, the coating reactor generates high-temperature asphalt fumes containing graphite dust and tar. These fumes require effective treatment to meet environmental protection requirements. Currently, commonly used exhaust gas treatment systems have two spray and flushing devices. While these can treat the fumes to some extent, they also have some problems. For example, when the water pressure is unstable, the spray nozzles can easily create blind spots, resulting in incomplete treatment of the fumes. Dust and tar in the untreated fumes will continue to rise, and long-term accumulation can lead to blockage of the exhaust pipes, increasing the workload and maintenance costs of manually cleaning the circulating water pipes and exhaust pipes. Utility Model Content

[0003] The purpose of this utility model is to provide a spray purification tank that can form a uniform water curtain and more water mist through the spray mechanism, thereby increasing the contact area between water and flue gas and improving the uniformity and stability of the water flow.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model discloses a spray purification tank, including a tank body and a spray mechanism disposed in the tank body. The spray mechanism includes a water inlet pipe disposed at the top of the tank body and a flow guiding component for forming a water curtain disposed below the water outlet end of the water inlet pipe.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Please see Figure 1 and 2 In this embodiment, a spray purification tank includes a tank body 1 and a spray mechanism 2 disposed inside the tank body 1. The spray mechanism includes a water inlet pipe 21 disposed at the top of the tank body 1 and a flow guiding component 22 disposed below the water outlet end of the water inlet pipe 21 for forming a water curtain.

[0024] Furthermore, the flow guiding component 22 includes an upward-opening bowl-shaped structure 221 with a water outlet hole (not shown in the figure) at its bottom. Circulating water is introduced into the tank 1 from the inlet pipe 21 and flows towards the bowl-shaped structure 221. A small amount of water flows downward from the water outlet hole of the bowl-shaped structure 221, while most of the water accumulates in the center of the bowl-shaped structure 221 and overflows from its edge, forming a uniform water curtain.

[0025] Furthermore, there are multiple water outlets, which are evenly distributed outward from the outlet end of the inlet pipe 21. The water outlets have a small diameter, and the slow water flow forms a fine stream without affecting the water storage of the bowl-shaped structure 221.

[0026] Furthermore, the flow guiding assembly 22 also includes a baffle cover 222 disposed below the bowl-shaped structure 221. The outer periphery of the baffle cover 222 is connected to the inner wall of the tank body 1, and its center is concentrically arranged with the bowl-shaped structure 221. The water curtain flows towards the baffle cover 222 and then flows downward from the center of the baffle cover 222, forming a secondary water curtain, increasing the water atomization, and better washing away impurities in the smoke and dust.

[0027] Furthermore, a smoke inlet 11 is provided on the side wall of the tank body 1, and the flue gas to be treated enters the tank body 1 through the smoke inlet 11.

[0028] Furthermore, an inspection port 12 is provided on the side wall of the tank body 1, which is located below the smoke inlet 11.

[0029] Furthermore, the bottom of the tank body 1 is provided with a slag receiving plate 3, which is used to collect non-gaseous impurities such as tar and dust in the flue gas. The edge of the slag receiving plate 3 forms a certain gap with the inner wall of the tank body 1 to facilitate water overflow.

[0030] Furthermore, the end of the slag receiving plate 3 near the inspection port 12 is inclined downwards, so that impurities roll down to the position near the inspection port 12 by gravity, making it easy for manual cleaning.

[0031] Furthermore, a baffle 4 is provided at the downward-sloping end of the slag receiving plate 3 to block non-gaseous impurities. The downward-flowing water overflows from the slag receiving plate 3 and the baffle 4 and eventually enters the drain outlet 14 at the bottom, where it is recycled and reused.

[0032] Furthermore, the tank body 1 is provided with a smoke exhaust port 13 at the top and a drain outlet 14 at the bottom. The drain outlet 14 is connected to the water inlet pipe 14 through a circulation pipe. A power pump and a purifier are connected to the circulation pipe for regular secondary cleaning. The circulating water is introduced into the water inlet pipe 21 for reuse through the circulation pipe.

[0033] In operation, flue gas enters the tank 1 through the inlet 11, while circulating water enters the tank 1 through the inlet pipe 21. The flue gas rises, and the circulating water flows downwards. When the flue gas and circulating water meet, impurities in the flue gas are captured by the circulating water and fall down. The purified flue gas flows out through the exhaust port 13. The downward-flowing circulating water forms a water curtain under the action of the bowl-shaped structure 221 (a small portion of the water flows directly downwards from the outlet hole, forming a fine stream), and flows towards the baffle cover 222. Under the action of the baffle cover 222, the secondary water curtain flows downwards, creating more water mist. This increases the contact area between the flue gas and water, improving the efficiency of capturing particulate matter and tar. The water that captures impurities falls to the slag receiving plate 3. As impurities accumulate, heavier oily sludge impurities deposit on the lower part of one side of the baffle 4, while the water overflows from the edge of the baffle 4 or the slag receiving plate 3 and flows to the drain port 14 at the bottom for collection. The treated circulating water is then reintroduced into the inlet pipe 21 for continued recycling.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
