[0020] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0021] In this disclosure, unless otherwise indicated, the directional terms "inside" and "outside" refer to the "inside" and "outside" relative to the outline of the corresponding component itself. Furthermore, the use of terms such as "first" and "second" is intended to distinguish different components and does not imply order or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings represent the same elements. Those skilled in the art should understand that the above definitions are intended only to explain and illustrate this disclosure and should not be construed as limitations of this disclosure.

[0022] According to the specific embodiment of the present disclosure, Figure 1 As shown, a dust suppression and slag discharge device is provided, which includes: a slag bin 1, which is arranged at the bottom of the boiler of a power plant for storing slag, and the slag bin 1 is provided with a slag discharge port connected to the boiler; a dust cover 2, the dust cover 2 is provided at the slag discharge port, and is provided with a first opening connected to the slag discharge port; and a spray mechanism 3, the spray mechanism 3 includes a first spray assembly 31, the first spray assembly 31 includes a first spray pipe and a plurality of first spray parts, the first spray pipe is arranged on the inner circle of the dust cover 2, and the plurality of first spray parts are arranged at intervals in the first spray pipe.

[0023] Through the above technical solution, the dust cover 2 is arranged at the slag discharge port to reduce the escape of dust at the slag discharge port. By providing multiple first spraying members on the inner circle of the dust cover 2, the first spraying members can spray liquid into the dust cover 2 to reduce the dust concentration in the dust cover 2 and reduce the dust escaping to the external environment. Moreover, by providing multiple first spraying members, the dust cover 2 can be fully covered, ensuring the effect of preventing the escape of dust in the dust cover 2. Therefore, by providing the spraying mechanism 3, the impact of dust on the environment around the dust cover 2 can be reduced, and the safety of workers' work can be improved.

[0024] In some embodiments of the present disclosure, reference Figure 1As shown, the spray mechanism 3 also includes a second spray assembly 32, which includes a second spray pipe and multiple second spray elements. The second spray pipe is located on the outer ring of the dust cover 2, and the multiple second spray elements are spaced apart in the second spray pipe. In this way, the second spray elements can spray liquid toward the periphery of the dust cover 2 to reduce the dust concentration outside the dust cover 2 and reduce the escape of dust into the external environment. Therefore, the second spray assembly 32 can cooperate with the first spray assembly 31 to ensure the cleanliness of the dust cover 2. Thus, by providing multiple second spray elements, the periphery of the dust cover 2 can be fully covered, further improving the dust prevention effect on the dust cover 2. This improves the safety of workers.

[0025] In some embodiments of the present disclosure, reference Figure 1 As shown, the spray mechanism 3 also includes a third spray assembly 33, which includes a third spray pipe and multiple third spray elements. The third spray pipe is arranged on the inner wall surface of the slag bin 1, and the multiple third spray elements are arranged at intervals with the third spray pipe. In this way, the third spray elements can spray liquid into the slag bin 1 to further clean dust escaping from the dust cover 2. Therefore, the third spray assembly 33 can work together with the first and second spray elements to clean the slag bin 1, thereby improving the environment within the slag bin 1. In this way, by providing multiple third spray elements, the slag bin 1 can be fully covered, further improving the dust prevention effect on the internal area of ​​the slag bin 1. This improves the safety of workers.

[0026] In some embodiments of the present disclosure, reference Figure 1 As shown, some of the multiple third spray elements are located at the door of the slag bin 1 and spaced along a circular arc, with the center of the arc located on the side of the arc facing away from the dust cover 2. Another portion of the multiple third spray elements are spaced around the inner wall of the slag bin 1. The portion of the third spray pipe located at the door is constructed in a circular arc. This allows the third spray elements on the third spray pipe at the door to be positioned close to the dust cover 2. This allows the third spray elements to cooperate with the second and first spray elements to improve coverage of the dust cover 2 and ensure dust suppression around the dust cover 2. This also prevents dust from spreading widely outside the door, ensuring dust suppression at the door. Another portion of the third spray elements are arranged around the inner wall of the slag bin 1, cooperating with the third spray elements at the door to provide sufficient coverage within the slag bin 1. The third spray elements at the door are arranged in a denser to sparser pattern from the ends to the center, facilitating uniform liquid distribution within the arc-shaped coverage area.

[0027] In some embodiments of the present disclosure, reference Figure 1As shown, the first spray member is rotatably mounted on the first spray pipe. Thus, by rotatably mounting the first spray member on the first spray pipe, when the slag truck enters the slag bin 1, the first spray member sprays perpendicularly to the inside of the dust cover 2, thereby lowering the temperature at the dust cover 2 and reducing the dust and smoke generated during the slag discharge process. When the slag truck is in place and ready to begin slag discharge, the first spray member can be rotated toward the slag discharge port to spray the dust passing through the slag discharge port, thereby ensuring that the dust entering the dust cover 2 is fully covered.

[0028] In some embodiments of the present disclosure, reference Figure 1 As shown, the second spray member is rotatably mounted to the second spray pipe. By rotatably mounting the second spray member to the second spray pipe, when the slag truck is in position and ready to begin slag discharge, the second spray member sprays perpendicularly to the sidewall of the dust cover 2 toward the outside of the dust cover 2, thereby lowering the temperature outside the dust cover 2 and reducing dust and smoke entering the slag bin 1 through the dust cover 2. When slag discharge begins, the second spray member can rotate toward the first opening of the dust cover 2 to spray dust escaping through the first opening, ensuring sufficient coverage of dust outside the dust cover 2.

[0029] In some embodiments of the present disclosure, reference Figure 1 As shown, the third spray member is rotatably mounted on the third spray pipe. By rotatably mounting the third spray member on the third spray pipe, at the beginning of slag discharge, the third spray member on the arc line at the bin door can rotate a certain angle toward the opening of the dust cover 2 to spray the first opening of the dust cover 2, further reducing dust and smoke at the beginning of slag discharge. Then, the third spray member on the inner wall of the slag bin 1 can rotate to spray toward the first opening of the dust cover 2 to increase the coverage of dust and smoke around the dust cover 2. During the slag discharge process, the third spray member on the arc line of the bin door sprays toward the dust cover 2 to prevent dust from escaping outside the slag bin 1. The third spray member on the inner wall of the slag bin 1 can rotate to be perpendicular to the inner wall to reduce dust or smoke inside the slag bin 1 during the slag discharge process.

[0030] In this way, during the slag discharge process, any group of the first spray member, the second spray member, and the third spray member can be rotated toward the first opening of the dust cover 2 or the slag discharge port, so as to spray the dust and smoke that enter the slag bin 1 through the dust cover 2, thereby reducing the escape of dust during the slag discharge process. It is also possible to rotate two of the first spray member, the second spray member, and the third spray member toward the slag discharge port or the first opening of the dust cover 2 as needed, and the other one perpendicular to the side wall of the dust cover 2 or the inner wall of the slag bin 1, so as to ensure the spray coverage rate at the dust cover 2 while reducing the working steps when controlling the rotation. The present disclosure does not limit this. For example, the first spray member and the second spray member can be rotated toward the dust cover 2 or the slag discharge port, and the third spray member sprays perpendicular to the wall. In this way, while preventing the escape of dust and smoke from the dust cover 2, the interior of the slag bin 1 can be sprayed to prevent dust from escaping inside the slag bin 1.

[0031] In addition, the first, second, and third spray parts can all be rotatably arranged to cover a wider area to accommodate different spraying or cleaning needs. The first, second, and third spray parts can all be configured as nozzles. By precisely controlling the spraying angle and range of the nozzles, unnecessary water consumption can be reduced and water resource utilization efficiency can be improved. When the nozzles are rotatably arranged horizontally, the spray coverage can be ensured, thereby reducing the number of nozzles and saving costs. When the nozzles are rotatably arranged vertically, sufficient contact between the sprayed liquid and dust can be ensured, improving cleaning efficiency and quality.

[0032] Spiral mist nozzles can be used for all nozzles, and the dust shield 2 at the slag outlet is constructed as a square dust shield 2. A first spray pipe and first spray element are installed inside the dust shield 2, 200 mm from the edge of the shell, and around the dust shield 2. The spacing between the multiple first spray elements is controlled at 150-180 mm, achieving 150% coverage of the area inside the dust shield 2 and ensuring dust suppression within the dust shield 2. The vertical distance between the first spray pipe where the first spray element is installed and the slag outlet is controlled at -50-65 mm, thereby effectively preventing dust from escaping from the interior of the slag outlet dust shield 2.

[0033] The second spray pipe is set at 280mm outside the dust cover 2 and surrounds the outside of the dust cover 2. The height is 180mm from the bottom of the dust cover 2 and 80~100mm from the outer edge of the conventional slag truck. The intervals between multiple second spray parts are controlled at 240-320mm, which can achieve a 150% coverage rate of the area within 1000mm outside the dust cover 2, ensuring the dust suppression effect in the area within 500mm outside the dust cover 2. The distance between the second spray pipe where the second spray part is installed and the bottom of the dust cover 2 can be set to -80mm to prevent dust from spreading to the slag discharge room outlet on a large scale.

[0034] The third spray elements, located on both sides of the arc away from the bin door, are spaced 100-120mm apart. The third spray elements located between the arc and the quarter semicircle are spaced 180-200mm apart. This achieves 150% coverage from 1000mm outside the dust cover 2 to 1000mm inside the bin door, ensuring effective dust suppression within this area. The third spray elements on the inner wall of slag bin 1 are spaced 80-100mm apart, achieving 150% coverage of the bin door area, ensuring effective dust suppression at the bin door and preventing widespread dust spread outside the slag compartment door.

[0035] Among them, the intervals between the first spray member, the second spray member and the third spray member, and the heights of the first spray pipe, the second spray pipe and the third spray pipe can be set according to actual work needs, and the present disclosure does not limit this.

[0036] In some embodiments of the present disclosure, reference Figure 1 As shown, the dust suppression and slag discharge device includes a first pipeline 41 and a filter element 5. The first pipeline 41 is connected to the spray mechanism 3, and the filter element 5 is installed in the first pipeline 41 to filter the medium passing through the first pipeline 41. In this way, the filter element 5 can filter the medium passing through the first pipeline 41 to remove impurities such as suspended particles in the water, ensure the cleanliness of the water and improve the water quality. As a result, the risk of nozzle clogging and wear during spraying can be reduced, the flushing effect can be improved, maintenance costs can be reduced, and the service life of the spray mechanism 3 can be extended.

[0037] In some embodiments of the present disclosure, reference Figure 1 As shown, the dust suppression and slag discharge device further includes a second pipeline 42 and a dosing pump 6. One end of the second pipeline 42 is connected to the dosing pump 6, and the other end is connected to the spray mechanism 3. The dosing pump 6 can be used to add a descaling agent to the second pipeline 42 to regularly flush the pipeline and nozzles in the spray mechanism 3, thereby unblocking the spray mechanism 3 and reducing scaling or blockage that affects the spraying effect, thereby ensuring long-term stable operation of the dust suppression and slag discharge device.

[0038] In some embodiments of the present disclosure, reference Figure 1 As shown, one of the first pipe 41 and the second pipe 42 is connected to the spray mechanism 3. Thus, when the first pipe 41 is connected to the spray mechanism 3, the slag bin 1 can be sprayed to reduce the dust concentration in the slag bin 1 and the impact of the dust on the surrounding environment. When spraying is not required, the first pipe 41 is disconnected from the spray mechanism 3, and the second pipe 42 is connected to the spray mechanism 3 to allow the descaling agent added to the second pipe 42 to flow through the spray mechanism 3, thereby clearing the spray mechanism 3 and reducing blockage or wear of the pipes and nozzles in the spray mechanism 3.

[0039] In some embodiments, the dust suppression and slag discharge device also includes a recovery pipeline, which is connected to the spray mechanism 3. Thus, the water after flushing the first pipeline 41 in the spray mechanism 3 and the water after descaling and cleaning the second pipeline 42 can be recovered and pumped into the wastewater treatment system of the power plant through a sedimentation tank and a vertical pump for purification and recovery to achieve recycling.

[0040] In some embodiments of the present disclosure, reference Figure 1 As shown, the dust suppression and slag discharge device also includes a detector 8 and an alarm 7. The detector 8 is electrically connected to the alarm 7 and is used to detect the height of the slag truck. Thus, when the truck enters the slag bin 1, the detector 8 can detect whether the height of the slag truck is lower than the height of the spray mechanism 3. When the height of the slag truck is 150 mm lower than the bottom of the third spray pipe, the slag truck can pass through. When the height of the slag truck exceeds 150 mm from the bottom of the third spray pipe, the slag truck may rub against the third spray pipe or the third spray member. The alarm 7 can issue a warning to remind the slag truck to stop entering, thereby ensuring the safety of the spray mechanism 3. The height between the slag truck and the third spray pipe can be set as needed, and this is not limited by the present disclosure.

[0041] In some embodiments of the present disclosure, reference Figure 1 As shown, the dust suppression and slag discharge device also includes a lifting mechanism. The spray mechanism 3 includes a third spray assembly 33, which includes multiple third spray elements and a third spray pipe. The lifting mechanism is connected to the third spray pipe to drive the third spray pipe up and down. In this way, when the height of the slag truck exceeds the bottom of the third spray pipe by 150 mm and the alarm 7 sounds, the lifting mechanism can drive the third spray pipe to rise to avoid the slag truck, allowing the slag truck to continue to enter the slag bin 1 without colliding with the third spray assembly 33.

[0042] In some embodiments of the present disclosure, the slag discharge dust suppression device can also optimize the logic of the existing negative pressure dust collection system. Specifically, the slag discharge door opening permission condition is set to the negative pressure system electric valve fully open signal to ensure that the negative pressure dust suppression system is normally activated before slag discharge. The negative pressure electric valve interlock closing condition is set to close 150 seconds after receiving the slag discharge door fully closed signal. In this way, the negative pressure dust suppression system can be reliably exited to absorb residual dust, reduce furnace air leakage, and achieve energy conservation. This disclosure is not limited to this.

[0043] Below, reference Figure 1As shown, the present disclosure will provide a detailed introduction to the specific use of the dust suppression and slag discharge device in conjunction with the above-mentioned specific embodiments. When the slag truck needs to enter the slag bin 1 to discharge slag, 30 seconds before the slag bin door is opened, the first spray assembly 31 is opened, and the angle of the first spray component remains unchanged in the vertical direction. 15 seconds before the slag truck is in position and the slag door is opened, the first spray component is rotated 45 degrees toward the inner slag discharge port (the rotation process takes 5 seconds) to continue spraying. At the same time, the second spray assembly 32 outside the dust cover 2 is opened, and the angle of the second spray component remains unchanged in the initial vertical direction to continue spraying. Slag discharge begins. 15 seconds after the slag discharge door opens, the second spray element rotates 45 degrees toward the dust suppression hood to continue spraying. 60 seconds after the slag discharge door opens, the third spray element of the arc portion of the third spray assembly 33 opens to spray, and the third spray element rotates 30 degrees toward the dust cover 2 to spray. After spraying for 60 seconds, the third spray element of the arc portion returns to the vertical position to continue spraying. At the same time, the third spray element on the inner wall of the slag bin 1 is opened and rotated 30 degrees toward the dust suppression hood to spray. At this time, all three spray assemblies are open and continue spraying. The nozzle angles of each spray assembly remain unchanged until the slag at the rear of the slag discharge vehicle is full.

[0044] After the tail of the slag truck is fully loaded with slag, the slag discharge door is closed. Ten seconds after the door is closed, all nozzles of the spray mechanism 3 return to their vertical orientation and continue spraying. The slag truck then reverses to the appropriate position to prepare for further slag loading. The previous logic repeats, adjusting the angles of the corresponding nozzles at different time intervals to spray and suppress dust. (Note that the spray system on each layer does not close after opening; only the corresponding nozzle angles are adjusted.) When the second slag truck is fully loaded, 10 seconds before the slag truck starts, all nozzles of the spray mechanism 3 return to their vertical orientation and continue spraying. Ten seconds after the slag truck exits the slag discharge room, the first spray assembly 31 is closed. After 30 seconds, the second spray assembly 32 is closed. After 120 seconds, the arc portion of the third spray assembly 33 is closed. After 180 seconds, the other portion of the third spray assembly 33 is closed. At this point, the entire spray mechanism 3 is closed.

[0045] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0047] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
