Description

Technical Field

[0001] This disclosure relates to the field of slag cooler technology, and more precisely, to a slag cooler. Background Technology

[0002] The slag cooler plays a crucial role in the boiler system. It can not only effectively control the differential pressure of the material bed, but also ensure the stable operation of the entire system by cooling and discharging the high-temperature slag generated during combustion.

[0003] However, in actual operation, especially when the boiler burns high-ash coal or is under high load, the combustion of high-ash coal produces a large amount of slag, which often has high viscosity and temperature. This slag requires the slag cooler to operate at higher speeds to process the slag in a timely manner. However, this high-speed operation can easily lead to slag flow accidents. A slag flow accident refers to slag failing to be sufficiently cooled or discharged in time, instead flowing inside the slag cooler, thus blocking the equipment outlet or damaging other components. This situation not only severely interferes with the normal function of the slag cooler and reduces its cooling efficiency, but may also cause greater safety hazards, such as equipment overheating or even a fire.

[0027] This disclosure provides a slag cooler, including a slag discharge pipe, a drum, and a motor. The slag discharge pipe includes a slag discharge port and is configured to transport coal slag. The drum is connected to the slag discharge pipe and has two opposite ends, one end of which is provided with a feed inlet and the other end with a discharge outlet. The slag discharge port of the slag discharge pipe is connected to the feed inlet. Blades are provided in the inner cavity of the drum. Coal slag enters the drum through the feed inlet and is spirally transported to the discharge outlet by the blades under the rotation of the drum. A baffle is provided at the end of the inner cavity of the drum near the slag discharge port, and the height of the baffle is lower than the height of the blades. The motor is configured to drive the drum to rotate.

[0028] The slag cooler provided in this disclosure has a baffle at one end of the inner cavity of the drum near the slag outlet, and the height of the baffle is lower than the height of the blades, so as to ensure that there is a certain material thickness at the discharge port of the slag cooler. The accumulated material can form resistance to the newly fed slag and avoid the occurrence of slag flow accidents.

[0029] For ease of understanding, please refer to the following: Figures 1 to 3 The specific structure and working principle of the slag cooler disclosed herein will be described in detail with reference to one embodiment.

[0030] like Figures 1 to 3 As shown, this disclosure provides a slag cooler, including a slag discharge pipe 1, a drum 2, and a motor 8. The slag discharge pipe 1 includes a slag discharge port 3 and is configured to transport coal slag. The drum 2 is connected to the slag discharge pipe 1 and has two opposite ends, one end of which is provided with a feed inlet and the other end with a discharge outlet. The slag discharge port 3 of the slag discharge pipe 1 is connected to the feed inlet. Blades 4 are provided in the inner cavity of the drum 2. The coal slag enters the drum 2 through the feed inlet and is spirally transported to the discharge outlet by the blades 4 under the rotation of the drum 2. A baffle 5 is provided at one end of the inner cavity of the drum 2 near the slag discharge port 3, and the height of the baffle 5 is lower than the height of the blades 4. The motor 8 is configured to drive the drum 2 to rotate.

[0031] Specifically, the slag cooler disclosed herein mainly comprises three parts: a slag discharge pipe 1, a drum 2, and a motor 8. The slag discharge pipe 1 is a channel connecting the upstream device and the slag cooler, conveying the high-temperature coal slag output from the upstream device to the inlet of the slag cooler. To ensure that the high-temperature coal slag can completely enter the slag cooler, the slag discharge pipe 1 includes at least a vertical section and an inclined section. The inclined section extends into the inner cavity of the drum 2 of the slag cooler, and a slag discharge port 3 is provided at the end of the inclined section. The high-temperature coal slag enters the inner cavity of the drum 2 of the slag cooler through the slag discharge port 3. A slag discharge valve 9 is also provided on the slag discharge pipe 1. The slag discharge valve 9 is used to isolate the high-temperature coal slag, and the conveying of the high-temperature coal slag can be controlled through the slag discharge valve 9.

[0032] The drum 2 is one of the core components of the slag cooler, effectively cooling and conveying the slag. The drum 2 has two opposite ends: an inlet at one end and a outlet at the other. High-temperature slag enters the drum 2 through the inlet and exits through the outlet. To improve the conveying efficiency of the slag within the drum 2, multiple blades 4 are installed inside. These blades push the slag along a spiral path to the outlet as the drum 2 rotates, ensuring continuous discharge. The blades 4 are typically spirally distributed on the inner wall of the drum 2, forming one or more spiral conveying paths. As the drum 2 rotates, the slag is pushed by these blades 4, moving forward along the spiral path until it reaches the outlet. This spiral conveying method not only ensures uniform distribution of the slag inside the drum 2 but also allows control of the slag conveying speed by adjusting the drum 2's rotation speed, thus achieving the desired cooling effect.

[0033] Furthermore, to further optimize the conveying process of coal slag, a baffle 5 is installed at the end of the inner cavity of the drum 2 near the slag outlet 3. The height of the baffle 5 is lower than the height of the blades 4. As mentioned before, since the blades 4 need to be set at a certain angle to the circumferential direction of the inner wall of the drum 2 in order to play a spiral conveying role, the baffle 5, in order to play a blocking role, has its extension surface set parallel to the circumferential direction of the inner wall of the drum 2. High-temperature coal slag enters the inner cavity of the drum 2 through the slag outlet 3. Under the blocking effect of the baffle 5, some of the high-temperature coal slag forms a certain accumulation. This ensures that there is a certain material thickness at the discharge port of the slag cooler. The accumulated coal slag can form a certain resistance to the newly entering coal slag, thereby avoiding the occurrence of slag flow accidents. In addition, the baffle 5 can also guide the coal slag to move forward along a predetermined spiral path, instead of sliding directly to the discharge port. This helps to prolong the residence time of the coal slag inside the drum 2, ensuring that the coal slag can be fully cooled. This not only effectively controls the differential pressure of the material layer, but also ensures that the slag cooler maintains good performance when processing high-ash coal or when the boiler is operating under high load, reducing the occurrence of slag flow accidents and thus improving the safe operation level of the equipment and boiler.

[0034] The motor 8 serves as the power source for driving the rotation of the drum 2, and its performance directly affects the working efficiency of the slag cooler. In this embodiment, the motor 8 is configured to drive the drum 2 to rotate, ensuring that the drum 2 can run smoothly at a preset speed, so that the slag can be uniformly cooled inside the drum 2 and smoothly conveyed to the discharge port.

[0035] In one embodiment of this disclosure, the conveying direction of the slag cooler is referred to as the front, and the baffle 5 is disposed in front of the slag outlet 3.

[0036] like Figures 1 to 2As shown, specifically, considering the conveying direction of the slag cooler (denoted as forward), the baffle 5 is positioned in front of the slag outlet 3. This ensures that the baffle 5 can block the movement of the high-temperature slag in the direction of movement, thus creating a certain material thickness at the slag cooler's discharge port. The accumulated material can provide resistance to newly entering slag, preventing slag spillage accidents. Furthermore, to further enhance the stability and reliability of the slag cooler, support structures are installed on both sides of the drum 2. These support structures not only ensure the stability of the drum 2 during high-speed rotation but also effectively disperse the centrifugal force generated during drum 2 rotation, reducing the impact of vibration on the equipment.

[0037] In one embodiment of this disclosure, a baffle 5 is disposed around two adjacent blades 4, and the baffle 5 is configured as a closed annular structure.

[0038] Specifically, such as Figures 1 to 2 As shown, since the inner cavity of drum 2 needs to rotate during the conveying of high-temperature coal slag, in order to ensure that the baffle 5 inside drum 2 can play an effective blocking role at any rotation angle, the baffle 5 is designed as a closed ring structure and installed between two adjacent spiral blades 4. When the high-temperature coal slag enters drum 2 from the slag outlet 3, it is first driven forward by the spiral blades 4 below and eventually reaches the position of baffle 5. Baffle 5 intercepts a portion of the coal slag, causing it to accumulate at baffle 5 to form a material pile of a certain height, which is usually equal to or slightly higher than the height of baffle 5. The remaining coal slag can pass over the top of baffle 5 and continue to be driven forward by the blades 4 in front of baffle 5, and finally discharged from drum 2 through the discharge port. This design can not only effectively control the distribution and flow of coal slag in drum 2, but also ensure that drum 2 maintains a good blocking effect at all times during rotation.

[0039] In one embodiment of this disclosure, the baffle 5 is a telescopic structure, including at least two nested first baffle segments and second baffle segments, which are movably connected and configured to adjust the height of the baffle 5.

[0040] To better adapt the slag cooler to various speed requirements in actual operation and improve its adaptability to different working conditions, the baffle 5 is designed as a telescopic structure. Specifically, the baffle 5 consists of at least two nested first and second baffle sections, which are connected by a movable connection. This movable connection allows the first and second baffle sections to move relative to each other as needed, thereby changing the overall height of the baffle 5.

[0041] When a higher baffle 5 is required, this can be achieved by reducing the overlap between the first and second baffle segments; conversely, if a lower baffle 5 is required, the overlap between the two baffle segments can be increased. The minimum height of baffle 5 is equal to the height of either the first or second baffle segment, while the maximum height is the sum of both. In other words, by simply adjusting the relative positions of the two baffle segments, the height of baffle 5 can be flexibly changed to meet different working requirements.

[0042] In this embodiment, the first and second baffle sections can be designed to be the same height, or they can be set to different heights according to the needs of different working conditions. The arrangement of the first and second baffle sections not only simplifies the operation of the slag cooler but also improves its ability to handle various working conditions. Through this retractable baffle 5, the slag cooler can better control the flow and distribution of high-temperature coal slag while ensuring efficient operation, thus improving the reliability and efficiency of the equipment.

[0043] In one embodiment of this disclosure, a slide gate valve 6 is provided in the inner cavity of the slag discharge pipe 1. The slide gate valve 6 includes: a valve body, the valve body having a channel and an interface that mates with a slide gate seal; a slide gate seal located within the valve body; and a transmission device configured to drive the slide gate seal to move.

[0044] To further improve the stability and controllability of the conveying process, such as Figure 1 and Figure 3 As shown, a slide gate valve 6 is specially installed inside the slag discharge pipe 1. The slide gate valve 6 runs through the entire cross-section of the slag discharge pipe 1 and is mainly composed of three key components: a valve body, a slide gate seal, and a transmission device. Specifically, the valve body has a channel inside for accommodating the slide gate seal. Driven by the transmission device, the slide gate seal can move back and forth horizontally within the channel inside the valve body.

[0045] When it is necessary to close the slag discharge pipe 1, the slide gate seal moves through the valve body interface to a position where it is in complete contact with the inner wall of the slag discharge pipe 1, thereby effectively sealing the slag discharge pipe 1 and preventing the high-temperature slag from continuing to flow out. Conversely, when the slide gate seal separates from the inner wall of the slag discharge pipe 1, the slag discharge pipe 1 can continue to transport high-temperature slag normally.

[0046] By incorporating the slide gate valve 6, the amount of slag discharged can be controlled more flexibly and efficiently, and the amount of slag discharged at a time can be significantly increased, thereby preventing slag spillage accidents caused by poor slag discharge. Furthermore, especially when frequent adjustments to the slag discharge rate are required, the slide gate valve 6 helps improve the overall system efficiency and reliability, thus enhancing the overall operating efficiency and safety of the slag cooler system.

[0047] In one embodiment of this disclosure, the transmission device is a manually operated mechanism, including a handwheel or handle configured to drive the insert seal to move horizontally.

[0048] Specifically, the transmission device includes a central shaft, with a handwheel or handle fixed to one end and the other end connected to the slide gate seal. When the operator pulls the handwheel or handle, the central shaft rotates, and this rotation is converted into linear motion in the horizontal direction via the transmission mechanism. This allows the slide gate seal to move back and forth horizontally, thereby opening and closing the slag discharge pipe 1. Setting the transmission device as a manual operation mechanism makes operation simpler and maintenance easier. The handwheel or handle is typically large enough for the operator to easily grip and apply sufficient force to drive the slide gate seal. Furthermore, to improve operational safety and stability, the handwheel or handle is equipped with anti-slip textures or other anti-slip measures. The transmission device in this embodiment is not only simple in structure and easy to maintain, but also provides reliable control in situations of unstable power supply or emergencies, ensuring the normal operation of the slag discharge pipe 1.

[0049] In one embodiment of this disclosure, a cooling pipe 10 is provided in the inner cavity of the drum 2. The cooling pipe 10 is evenly distributed in the inner cavity of the drum 2 and extends out from the other end of the drum 2.

[0050] To further improve the cooling efficiency of the slag cooler, cooling pipes 10 are specially installed inside the drum 2. These cooling pipes 10 are evenly distributed inside the drum 2. When high-temperature coal slag enters the drum 2 and is conveyed forward by the spiral blades 4, the cooling pipes 10 are indirectly cooled by the high-temperature coal slag. This design effectively utilizes the heat of the high-temperature coal slag and helps to improve energy efficiency.

[0051] Specifically, the cooling pipe 10 is made of high-temperature resistant material and can withstand the heat of high-temperature coal slag without damage. For example... Figure 1 As shown, the cooling pipe 10 extends from the other end of the drum 2, i.e., the discharge port, and connects to an external cold source. In this way, when cooling water or other cooling media circulates through the cooling pipe 10, it can remove the heat transferred to the pipe by the high-temperature coal slag, thereby reducing the temperature of the coal slag. To ensure cooling effectiveness, the cooling pipe 10 is typically evenly distributed along the length of the drum 2 and arranged in a spiral pattern within the drum 2's inner cavity to increase the contact area and time with the coal slag. Through this configuration, the cooling pipe 10 not only effectively reduces the temperature of the high-temperature coal slag but also improves the overall thermal efficiency of the slag cooler and reduces energy waste.

[0052] like Figure 1As shown, in one embodiment of this disclosure, a metal expansion joint 7 is provided on the slag discharge pipe 1. The metal expansion joint 7 includes: a bellows; and flange connectors located at both ends of the bellows and configured to connect both ends of the bellows to the slag discharge pipe 1 respectively.

[0053] Specifically, since the slag discharge pipe 1 is mainly used to transport high-temperature coal slag to the slag cooler, a metal expansion joint 7 is installed on the slag discharge pipe 1 to prevent excessive pressure caused by high temperature, which could easily damage the slag discharge pipe 1. After the high-temperature coal slag enters the slag discharge pipe 1, the pressure inside the slag discharge pipe 1 increases. At this time, the metal expansion joint 7 balances the pressure inside the slag discharge pipe 1 through its own expansion, thereby protecting the slag discharge pipe 1 from damage.

[0054] Specifically, the metal expansion joint 7 mainly consists of a bellows and flange connections. The bellows is a special type of pipe capable of withstanding high temperatures and pressures. Its structure allows for axial or radial expansion and contraction when subjected to temperature changes, thus absorbing displacement caused by thermal expansion and contraction. Flange connections are located at both ends of the bellows, tightly connecting it to the slag discharge pipe 1 to ensure the sealing and stability of the entire system. When high-temperature coal slag enters the slag discharge pipe 1, the temperature and pressure inside the pipe rise accordingly. At this time, the metal expansion joint 7 balances the pressure inside the slag discharge pipe 1 through its own expansion, effectively protecting the slag discharge pipe 1 from damage.

[0055] To ensure the effective functioning of the metal expansion joint 7, the bellows is typically made of high-temperature and corrosion-resistant metal materials, capable of withstanding the extreme conditions posed by high-temperature coal slag. The flange connections require excellent sealing performance to prevent coal slag leakage and must withstand high-temperature and high-pressure environments. Furthermore, for ease of installation and maintenance, the flange connections may also include corresponding positioning holes and fasteners for convenient on-site assembly and adjustment. By installing the metal expansion joint 7 on the slag discharge pipe 1, not only can the stress changes in the pipeline caused by temperature differences be effectively mitigated, but the safety and service life of the entire system can also be improved. In addition, the design of the metal expansion joint 7 can reduce downtime and maintenance costs due to pipeline damage, further improving the reliability and economic efficiency of the system.

[0056] In one embodiment of this disclosure, a temperature sensor is provided inside the drum 2, and the temperature sensor is configured to monitor the temperature inside the drum 2.

[0057] Specifically, temperature sensors typically employ high-precision thermocouples or resistance temperature detectors (RTDs) to monitor the temperature inside the drum 2 cavity in real time and transmit the temperature data to the control system. Based on the received temperature signal, the control system automatically adjusts the flow rate or temperature of the cooling medium to ensure that the slag inside the drum 2 cavity achieves the desired cooling effect. To improve the accuracy of temperature monitoring, the temperature sensors are designed to withstand high-temperature environments and possess good anti-interference capabilities. Furthermore, to ensure long-term stable operation of the temperature sensors, they may also be equipped with waterproof and dustproof protective measures.

[0058] By installing a temperature sensor inside the drum 2 cavity, the temperature inside the drum 2 cavity can be monitored in real time and fed back to the control system in a timely manner for better temperature adjustment. This ensures that the slag cooler maintains optimal operating conditions throughout the cooling process, improving cooling efficiency and safety, and also helps extend the equipment's service life.

[0059] In one embodiment of this disclosure, a pressure sensor is provided inside the slag discharge pipe 1, and the pressure sensor is configured to monitor the pressure inside the slag discharge pipe 1.

[0060] Specifically, the pressure sensor is typically made of high-temperature and corrosion-resistant materials, capable of withstanding the extreme conditions posed by high-temperature coal slag. It accurately measures the pressure within the slag discharge pipe 1 and transmits the pressure data to the control system. Based on the received pressure signal, the control system automatically adjusts the operating state of the slag discharge pipe 1, for example, by adjusting the opening of the slide valve 6 to control the flow rate of coal slag, or by activating the metal expansion joint 7 to relieve pressure within the pipe. Furthermore, the pressure sensor is equipped with remote monitoring capabilities, allowing operators to monitor the pressure status of the slag discharge pipe 1 in real time from the control room.

[0061] By installing a pressure sensor inside the slag discharge pipe 1, the pressure inside the pipe can be monitored in real time, and feedback can be promptly sent to the control system for better pressure adjustment. This ensures that the slag discharge pipe 1 maintains a safe operating condition throughout the entire conveying process, preventing accidents caused by excessive pressure and extending the equipment's service life.

[0062] The slag cooler provided in this disclosure has a baffle 5 at one end of the inner cavity of the drum 2 near the slag outlet 3, and the height of the baffle 5 is lower than the height of the blade 4, so as to ensure that there is a certain material thickness at the discharge port of the slag cooler. The accumulated material can form resistance to the newly fed slag and avoid the occurrence of slag flow accidents.
