Description

Technical Field

[0001] This application relates to the technical field of cement raw material slag removal equipment, and in particular to a vibration-type raw material slag removal equipment for cement preparation. Background Technology

[0002] With the acceleration of industrialization, the amount of hazardous waste generated is increasing daily, posing a serious threat to the environment. Cement kiln co-processing of hazardous waste, as an effective treatment method, has been widely used in recent years due to its characteristics of high temperature, alkaline environment, and long material residence time, enabling the harmless, reduced-volume, and resource-based treatment of hazardous waste. However, the vibratory cement production process generates a large amount of waste gas containing various pollutants, such as acidic gases, heavy metals, and dioxins. If directly emitted without effective treatment, it will cause serious harm to the atmospheric environment and human health.

[0003] Existing waste gas treatment devices typically employ raw material processing components to treat waste gas. These components rapidly cool the waste gas, avoiding the temperature range where dioxins are easily generated, thus ensuring effective treatment. However, traditional raw material processing components use fixed nozzles, resulting in uneven spraying of the dust-suppressing liquid and uneven cooling of the waste gas, failing to meet the process requirements for waste gas treatment. Furthermore, fixed nozzles are prone to clogging during long-term use, making maintenance and replacement difficult, increasing operating costs and downtime. Summary of the Invention

The raw material processing component has a shell with an exhaust gas inlet and an exhaust gas outlet. Both the exhaust gas inlet and the exhaust gas outlet are located on the side wall of the shell, with the exhaust gas inlet being higher than the exhaust gas outlet. A rotating shaft is rotatably arranged inside the shell, and the rotating shaft has a plurality of atomizing nozzles for spraying dust-suppressing liquid. The rotating shaft is a hollow structure, and the dust-suppressing liquid flows through the interior of the rotating shaft to the atomizing nozzles for spraying.

[0009] Preferably, the spiral support is conical in shape, and the diameter of the spiral support gradually increases from top to bottom.

[0010] Preferably, the rapid cooling section and the uniform cooling section of the rotating shaft are detachable structures. The rapid cooling section has a mounting block at the bottom and a mounting slot at the top. The mounting block is installed in conjunction with the mounting slot. A mating sleeve is slidably provided at the bottom of the rapid cooling section. After sliding, the mating sleeve moves closer to or further away from the mounting block.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a vibration-type raw material slag removal device for cement preparation. (Refer to...) Figure 1 After the cement slag removal equipment performs vibration slag removal, it generates a large amount of waste gas. The waste gas enters the raw material processing component 1 through the waste gas inlet, where it is rapidly cooled to below 200°C, thus removing it from the dioxin formation range and preventing the re-synthesis of dioxins, thereby ensuring the quality of waste gas treatment. After being rapidly cooled, the waste gas passes through the raw material processing component 1, where its temperature is rapidly reduced, and acidic gases, dust, or impurity particles are also adsorbed. Finally, the treated gas enters the cyclone separator 2 through the outlet 420 for further processing, where water mist and untreated impurity particles are further removed, ensuring the cleanliness of the discharged waste gas. The water adsorbed in the raw material processing component 1 enters the flue gas treatment device 3 for further treatment, preventing its continuous accumulation in the raw material processing component 1.

[0026] Reference Figure 2 Furthermore, traditional raw material processing components use fixed nozzles, resulting in uneven spraying of the dust-suppressing liquid and uneven cooling of the exhaust gas. In contrast, this system uses a rotating shaft 430 to drive the atomizing nozzle 440, allowing the dust-suppressing liquid to be sprayed evenly and comprehensively within the housing 4, ensuring full contact with the exhaust gas and achieving uniform cooling. The design of the exhaust gas inlet 410 being higher than the outlet 420 creates a natural downward flow path for the exhaust gas within the housing 4, increasing the contact time between the exhaust gas and the dust-suppressing liquid, further improving cooling efficiency and ensuring that the exhaust gas can be rapidly cooled to a safe temperature. Traditional fixed nozzles are prone to clogging due to impurities in the exhaust gas; however, the atomizing nozzle 440 in this system, during rotation, utilizes centrifugal force to dislodge impurities near the nozzle, reducing the possibility of clogging and significantly lowering maintenance frequency.

[0027] Furthermore, this solution divides the internal space of the casing 4 into different functional sections, making the rapid cooling process more precise. At the exhaust gas inlet 410, in the emergency cooling section 432, as soon as the exhaust gas enters the raw material processing component 1, a dense spray of dust-suppressing liquid is applied through the atomizing nozzles 440 on the cross-shaped spray frame 4321 of the rapid cooling section 432. This achieves rapid cooling in the area with the highest exhaust gas temperature, effectively avoiding the temperature range where dioxins are easily generated. Since the exhaust gas has just entered the casing 4, the direct application of a large number of dense atomizing nozzles 440 ensures a very rapid temperature reduction, significantly reducing the amount of dioxins generated. The uniform cooling section 433 is designed to optimize the temperature uniformity of the exhaust gas. After rapid cooling in the rapid cooling section 432, the exhaust gas is sprayed with an appropriate amount of dust-suppressing liquid in the uniform cooling section 433, effectively adjusting the temperature differences within the exhaust gas and making the temperature more uniform when the exhaust gas exits the raw material processing component 1, providing better conditions for subsequent exhaust gas treatment.

[0028] Furthermore, the downward-facing atomizing nozzles 440 on the cross-shaped spray frame 4321 can form a fully covered cooling area the moment the exhaust gas enters. Because the nozzles are positioned higher than the exhaust gas inlet 410, the dust-suppressing liquid, under the combined effect of gravity and the nozzle's spray force, can more fully contact the high-temperature exhaust gas. The internal connection between the rotating shaft 430 and the internal connection of the cross-shaped spray frame 4321 ensures that the dust-suppressing liquid can be smoothly delivered to all positions of the cross-shaped spray frame 4321, improving the stability and reliability of the cooling effect.

[0029] Reference Figure 2 and Figure 5Furthermore, the equalization cooling section 433 is located below the rapid cooling section 432. The rapid cooling section 432 itself is relatively short and has densely arranged atomizing nozzles 440, enabling rapid cooling of the exhaust gas. The equalization cooling section 433 has a different function from the rapid cooling section 432. The equalization cooling section 433 is relatively longer, and the arrangement of atomizing nozzles 440 is relatively sparser than that of the rapid cooling section 432. Through its unique spiral support 4331, when the rotating shaft 430 rotates, it can not only mix the exhaust gas and dust-suppressing liquid more evenly, but also change the flow direction of the exhaust gas itself, further improving the uniformity of cooling. The spiral support 4331 itself has a spiral and conical structure. Compared with the traditional planar arrangement, the unique structure of the spiral support 4331 causes the dust-suppressing liquid to form a spiral liquid curtain after being sprayed, resulting in more thorough mixing with the exhaust gas. This thorough mixing accelerates the heat transfer process and improves cooling efficiency. Due to the disturbance effect of the spiral liquid curtain, when the rotating shaft 430 rotates, the atomizing nozzles 440 are more evenly distributed in space, improving the treatment effect of exhaust gas.

[0030] Reference Figure 1 Furthermore, due to the complex composition of the exhaust gas, and the fact that the rapid cooling section 432 and the uniform cooling section 433 are key components that withstand varying degrees of thermal shock during the exhaust gas treatment process, various problems inevitably arise requiring maintenance or replacement. Their detachable structure allows maintenance personnel to perform targeted maintenance on specific parts, reducing the possibility of replacing the entire rotating shaft 430 due to damage to local components, thus lowering equipment maintenance costs. When the atomizing nozzle 440 of the rapid cooling section 432 becomes severely clogged or damaged, only the rapid cooling section 432 needs to be disassembled for repair, without replacing the entire rotating shaft 430, saving significant maintenance time. This solution, through the cooperation of the mounting block 451 and the mounting slot 452, and the reinforcing connection of the mating sleeve 460, makes the connection between the rapid cooling section 432 and the uniform cooling section 433 tighter and more stable; during the rotation of the rotating shaft 430, it can effectively resist vibrations and displacements caused by centrifugal force, thermal stress, and the impact force of exhaust gas flow, ensuring the overall stability of the rotating shaft 430. To ensure a tight connection, the mounting block 451 is a rectangular protrusion, and the mounting slot 452 is a matching rectangular groove. The outer side of the mating sleeve 460 is hexagonal, and the inner side of the mating sleeve 460 is provided with internal threads. The bottom outer side of the rapid cooling section 432 is provided with external threads. The mating sleeve 460 slides by screwing on the threads. When the mating sleeve 460 is screwed to completely cover the connection between the mounting block 451 and the mounting slot 452, it is locked by thread self-locking. At this time, the mounting block 451 and the mounting slot 452 cannot be disassembled. Rotating the mating sleeve 460 in the opposite direction will unlock the lock and allow the rapid cooling section 432 and the cooling section 433 to be disassembled.

[0031] Reference Figure 2Furthermore, the water tank 5 is located at the top of the raw material processing component 1 and is close to the exhaust gas inlet 410. In actual use, the dust-suppressing liquid in the water tank 5 will not directly absorb the temperature of the high-heat exhaust gas, thus preventing a rise in temperature and reducing the quenching effect. Simultaneously, the water tank 5 is also close to the quenching section 432, maximizing the cooling effect of the quenching section 432. The water tank 5 is fixed to the top of the housing 4 by welding or bolting, ensuring a secure installation capable of withstanding its own weight and the gravity of the dust-suppressing liquid. The connection is sealed to prevent leakage of the dust-suppressing liquid. Additionally, the bottom of the water tank 5 has an outlet corresponding to the inlet 4311 on the active section 431, ensuring smooth flow of the dust-suppressing liquid into the active section 431. A water pump is connected to the inlet of the water tank 5, pumping the dust-suppressing liquid into the water tank 5. The pressure applied by the water pump effectively ensures the uniformity of the water sprayed from the atomizing nozzle 440.

[0032] Furthermore, in this design, the active section 431 is driven to rotate through the meshing of the active gear 630 and the driven gear 610. The gear transmission ensures that the rotating shaft 430 operates at a stable speed, effectively guaranteeing the uniformity of the dust-suppressing liquid sprayed by the atomizing nozzles 440. Simultaneously, the gear transmission has a high load-bearing capacity, capable of withstanding the large torque generated during the rotation of the rotating shaft 430. Since multiple atomizing nozzles 440 are mounted on the rotating shaft 430, and it is subject to multiple influences during rapid cooling and uniform cooling, including resistance from exhaust gas flow and the reaction force of the dust-suppressing liquid, a reliable power drive is required. The drive component 620 is located at the top of the housing 4, making the entire drive structure relatively easy to access. When maintenance, repair, or replacement of the drive component 620, the active gear 630, or the driven gear 610 is required, operators can perform the operation directly without disassembling numerous other components. Compared to designs that place the drive device in complex locations inside the equipment, this significantly saves maintenance time and labor costs.

[0033] Furthermore, the conical design at the bottom of the casing 4 allows the wastewater generated during the rapid cooling process to flow naturally to the wastewater outlet 470 under gravity, eliminating the need for additional power equipment to collect the wastewater. This saves energy and reduces the complexity and cost of the equipment. Compared to using pumping equipment to collect wastewater, this not only avoids potential pumping equipment failures but also reduces energy consumption. The wastewater can be discharged promptly from the wastewater outlet 470 and connected to the ash treatment device 3, preventing secondary pollution that might occur if the wastewater remains in the raw material processing component 1 for an extended period. The direct connection between the wastewater outlet 470 and the ash treatment device 3 makes the entire waste gas treatment system more seamless. From the generation of wastewater during rapid cooling of the waste gas to the timely delivery of the wastewater to the treatment device for processing, a tightly integrated process is formed, effectively treating the wastewater while also reducing the load on the overall structure of the raw material processing component 1. In particular, for the raw material processing component 1 of a large cement kiln co-processing hazardous waste center, the accumulation of a large amount of wastewater may put great pressure on the tower structure and affect its stability. By designing an efficient wastewater discharge system, the stability of the tower structure can be maintained, reducing equipment failures caused by structural deformation or damage, and further ensuring the long-term stable operation of the equipment.

[0034] Furthermore, the housing 4 of this device is also provided with a dedicated installation door 490 and an installation port 480. The installation port 480 includes two sets, respectively for the emergency cooling section 432 and the uniform cooling section 433. The size of each installation port 480 is adapted to the maximum outer diameter of the cross spray frame 4321 and the spiral support 4331, ensuring that the rotating shaft 430 can be removed or installed through the installation port 480 during maintenance. When the atomizing nozzle 440 is blocked or the rotating shaft 430 malfunctions internally, it can be quickly inspected or replaced through the installation door 490 and the installation port 480, effectively improving the quality and efficiency of the treatment.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
