Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of flue gas treatment, in particular to a flue gas treatment equipment. BACKGROUND
[0002] In the context of aluminum ash treatment, the "pyrometallurgical" process refers to a treatment process that recovers aluminum metal and converts hazardous substances from aluminum ash through a series of physical and chemical reactions by using high-temperature heating methods.
[0003] The high-temperature smelting process produces a large amount of high-temperature flue gas, and the composition of the flue gas is complex, so the flue gas must be strictly treated before being discharged. The flue gas is first sucked into the gas collection pipeline from the outlet of the smelting furnace under negative pressure to ensure no leakage. The flue gas is cooled to about 200°C from 800-1000°C, and at the same time, large-particle impurities in the flue gas are discharged from the bottom of the equipment after cooling.
[0004] If the cooling equipment used cannot reduce the temperature of the flue gas to the expected temperature, resulting in the flue gas staying in the dangerous temperature range of 50-500°C for too long, or failing to reduce to the target temperature, it will cause a series of serious consequences, such as the generation of a large amount of dioxins. The purpose of rapid cooling is to make the flue gas pass through this temperature window quickly, so that the reaction does not have enough time to proceed. If the cooling fails, the slow cooling of the flue gas in this temperature range is equivalent to providing a perfect "reaction kettle" for the synthesis of dioxins, resulting in a thousand-fold increase in their concentration.
[0005] However, in the prior art, the equipment for cooling the flue gas cannot cool the flue gas to the expected temperature, and at the same time, the discharge port at the bottom of the equipment is prone to pressure relief.

[0038] The treatment box 21 is the core place for flue gas purification, and its structural design ensures smooth flue gas flow; the filter plate 73 added to the exhaust pipe 23 can effectively capture escaped fine particles, significantly improving the final purification effect of flue gas; the design of the discharge hopper 24 and the collecting pipe 25 realizes the collection and temporary storage of dust, laying a foundation for subsequent intermittent and sealed dust discharge.
[0039] As Figures 1-2As shown, the cooling treatment mechanism 3 includes a protective pipe 31 fixedly arranged at the top of the treatment box 21, the protective pipe 31 is sleeved on the smoke inlet pipe 22, a water pipe cavity 32 is arranged in the protective pipe 31, a water inlet pipe 33 is arranged on the outer wall of the protective pipe 31, a plurality of spray heads 34 are arranged on the inner wall of the protective pipe 31, the water inlet pipe 33 is in communication with the water pipe cavity 32, and the plurality of spray heads 34 are respectively in communication with the water pipe cavity 32.

[0043] The working principle and beneficial effects of the above technical solution are as follows: the water pipe cavity 32 spirally arranged in the protective pipe 31 significantly prolongs the flow path and residence time of the cooling water in the protective pipe 31, and the plurality of spray heads 34 are spirally arranged to ensure that the water mist can uniformly cover the entire outer surface of the smoke inlet pipe 22, the spiral flow channel greatly increases the heat exchange area and time of the cooling water and the outer wall of the smoke inlet pipe 22, avoids the occurrence of cooling dead angles, and significantly enhances the cooling effect of the smoke inlet pipe 22. Example 3
[0044] Based on example 1, as shown in Figures 1-3As shown, the switching mechanism 4 includes a first rotating shaft 41, which is rotatably disposed inside the collection pipe 25. The first rotating shaft 41 is fixedly connected to a first flap 42, which is disposed inside the collection pipe 25. A first abutting arm 43 is fixedly disposed at one end of the first rotating shaft 41 extending outside the collection pipe 25. A drive box 44 is disposed at the bottom of the drain pipe. The side wall of the drive box 44 is fixedly connected to the collection pipe 25 through a connecting column 45. A second drain pipe 46 is disposed at the bottom of the drive box 44. A rotating shaft 47 is rotatably disposed inside the drive box 44. A water wheel 48 is disposed on the rotating shaft 47. A second abutting arm 49 for actuating the first abutting arm 43 is disposed at one end of the rotating shaft 47 extending outside the drive box 44. The bottom of the second drain pipe 46 is connected to the water storage tank 50. like Figures 3-5 As shown, it includes a second rotating shaft 51, which is disposed below the first rotating shaft 41. The second rotating shaft 51 is rotatably disposed inside the collecting pipe 25. The second rotating shaft 51 is fixedly connected to a second flap 52, which is disposed inside the collecting pipe 25. A third abutting arm 53 is fixedly disposed at one end of the second rotating shaft 51 that extends out of the collecting pipe 25 for being pushed by the second abutting arm 49. like Figure 2 As shown, a sealing frame 72 is provided inside the collecting pipe 25, and the two sealing frames 72 are respectively attached to the top of the first flap 42 in a horizontal state and the top of the second flap 52 in a horizontal state.
[0045] The working principle and beneficial effects of the above technical solution are as follows: The first rotating shaft 41 is rotatably installed inside the collection pipe 25. The first rotating shaft 41 is fixedly connected to the first flap 42 to control its opening and closing. The end of the first rotating shaft 41 extending out of the collection pipe 25 is fixedly provided with a first abutting arm 43. The wastewater discharged from the first drain pipe 37 flows into the drive box 44 at its bottom and impacts the water wheel 48 on the rotating shaft 47 to rotate, thereby driving the second abutting arm 49 extending out of the drive box 44 to rotate. The second abutting arm 49 periodically pushes the first abutting arm 43 during rotation, forcing the first rotating shaft 41 to rotate and open the first flap 42, realizing periodic dust discharge. The wastewater is finally discharged into the water storage tank 50 through the second drain pipe 46 at the bottom of the drive box 44 and then discharged away.
[0046] The design cleverly utilizes the kinetic energy recovery of wastewater as the sole power source to drive the dust removal action, eliminating the need for external motors or pneumatic devices and achieving "waste treatment with waste," thus saving energy and protecting the environment. This design ensures that the dust removal action is strictly synchronized with the discharge of cooling water, forming an automated logic of "dust removal action only occurs when cooling water is drained." The system is highly interconnected, reliable, and efficient.
[0047] The second rotating shaft 51 is arranged below the first rotating shaft 41, and the second rotating shaft 51 is arranged to rotate in the collecting pipe 25 and is fixedly connected with the second flap 52. The end of the second rotating shaft 51 extending out of the collecting pipe 25 is fixedly provided with a third abutting arm 53. The second abutting arm 49 on the rotating shaft 47 sequentially actuates the third abutting arm 53 and the first abutting arm 43 in the rotating process, thereby sequentially opening the second flap 52 and the first flap 42.
[0048] When the first flap 42 is opened for dust discharge, the second flap 52 is normally closed. When the second flap 52 is opened for dust discharge, the first flap 42 is normally closed. This can effectively prevent a large amount of external air from being sucked into the inside of the treatment box 21 during dust discharge, thereby maintaining the stability of the negative pressure and the smoke flow in the treatment box 21 and ensuring that the purification effect is not interrupted. The same set of water power driving devices is used to control the two flaps. The structure is compact, the action is coordinated and orderly, and the control is simple and reliable.
[0049] When the first flap 42 and the second flap 52 are rotated to the horizontal closed state, the top edges of the first flap 42 and the second flap 52 are tightly fitted with the two sealing frames 72, respectively.
[0050] The sealing performance of the first flap 42 and the second flap 52 in the closed state is greatly enhanced, dust leakage from the shaft gap and the edge of the first flap 42 and the second flap 52 is effectively prevented, and gas interflow through the collecting pipe 25 is completely eliminated. Good sealing performance ensures that the collecting pipe 25 can effectively temporarily store smoke dust, which is a prerequisite for the effective work of the locking mechanism 6. Example 4
[0051] On the basis of example 2, as Figure 1 , Figure 3 and Figure 4As shown, the locking mechanism 6 is arranged on the aggregate pipe 25, the locking mechanism 6 is in transmission connection with the switch mechanism 4, the locking mechanism 6 comprises a first sliding block 61 and a second sliding block 62, the first sliding block 61 is slidingly arranged at the bottom of the first flap 42, a first through hole 63 and a second through hole 64 are arranged on the side wall of the aggregate pipe 25, a first sliding rod 65 is limitingly inserted into the first through hole 63 through a clamping assembly 66, one end of the first sliding rod 65 is hinged to the first sliding block 61, the other end of the first sliding rod 65 is outside the aggregate pipe 25, a guide sleeve 67 is fixedly arranged outside the aggregate pipe 25, a blocking block 68 is vertically inserted into the guide sleeve 67, the top of the blocking block 68 is connected with the other end of the first sliding rod 65 through a soft rope 69, a guide bracket 70 for receiving the blocking block 68 is fixedly arranged outside the aggregate pipe 25, the second sliding block 62 is slidingly arranged at the bottom of the second flap 52, a second sliding rod 71 is limitingly inserted into the second through hole 64 through the clamping assembly 66, one end of the second sliding rod 71 is hinged to the second sliding block 62, the other end of the second sliding rod 71 is outside the aggregate pipe 25. As Figure 3 shown, the clamping assembly 66 comprises a first clamping ring 661, two first clamping rings 661 are arranged on the first sliding rod 65 at intervals, and two second clamping rings 662 are arranged on the second sliding rod 71 at intervals.
[0052] The working principle and beneficial effects of the above technical solution are as follows: the first sliding block 61 is slidingly arranged at the bottom of the first flap 42, and the second sliding block 62 is slidingly arranged at the bottom of the second flap 52; when the first flap 42 and the second flap 52 are in a horizontal closed state, the first sliding block 61 is located on the first flap 42 away from the blocking block 68, and the second sliding block 62 is located on the second flap 52 away from the blocking block 68; the first perforation 63 and the second perforation 64 are arranged on the sidewall of the aggregate pipe 25, the first sliding rod 65 is inserted into the first perforation 63 through the clamping assembly 66, one end of the first sliding rod 65 is hingedly connected with the first sliding block 61, and the other end is located outside the aggregate pipe 25 and is connected with the blocking block 68 inserted into the guide sleeve 67 through the soft rope 69; when the first flap 42 is turned downward, the second flap 52 remains horizontal, the large-particle impurities on the first flap 42 fall onto the second flap 52, and the first sliding rod 65 slides obliquely downward in the first perforation 63, so that the blocking block 68 descends along the guide sleeve 67 to the guide bracket 70, at this time, the blocking block 68 abuts against the other end of the second sliding rod 71 to prevent the second flap 52 from being accidentally opened due to the large-particle impurities being too heavy, thereby achieving mechanical locking of the second flap 52; when the first flap 42 is turned upward to be horizontal to close the aggregate pipe 25, the first sliding rod 65 slides obliquely upward in the first perforation 63, the first sliding rod 65 pulls the blocking block 68 to ascend along the guide sleeve 67 and away from the guide bracket 70, at this time, the blocking block 68 does not abut against the other end of the second sliding rod 71, the second flap 52 is turned downward after the first flap 42 remains horizontal, and the second sliding rod 71 slides obliquely downward in the second perforation 64, thereby ensuring that the first flap 42 and the second flap 52 are opened in turn rather than simultaneously.
[0053] A purely mechanical and absolutely reliable locking mode is provided, which ensures that the flap of the device cannot be accidentally opened due to internal pressure fluctuations or the gravity of large-particle impurities during operation, thereby greatly improving the safety and stability of the device in operation.
[0054] When the first sliding rod 65 and the second sliding rod 71 slide in the first perforation 63 and the second perforation 64 respectively, the first clamping ring 661 is clamped in the first perforation 63, and the second clamping ring 662 is clamped in the second perforation 64.
[0055] The arrangement of the first clamping ring 661 and the second clamping ring 662 further strengthens the locking effect, so that the first sliding rod 65 and the second sliding rod 71 stably move in the first perforation 63 and the second perforation 64 respectively when moving, and are difficult to slide off by themselves due to vibration and the like, the structure is simple, easy to process and manufacture, and durable and reliable.

Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be enumerated and it is impossible to enumerate all the embodiments. The changes or variations derived from the above are still within the protection scope of the present application.
