[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. During the operation of a boiler, ash will inevitably accumulate on the heating surface, affecting the boiler's thermal efficiency and service life.

[0003] Therefore, boiler soot blowers can be used to remove ash from boilers. Existing boiler soot blowers mainly use high-pressure gas to blow the heating surface to remove ash. However, such soot blowers generate a lot of dust during the soot blowing process. When the soot blower stops working, the dust will enter the soot blower and damage it. Utility Model Content

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] The following reference Figures 1 to 4 Description of an anti-clogging structure and an array-type emission stream soot blower according to some embodiments of the present invention.

[0019] like Figures 1 to 4 As shown, an embodiment of this utility model provides an anti-clogging structure, comprising: The connector 1 has a through hole 2 inside. The through hole 2 is divided into two sections. One section has a circular cross-section, i.e., a circular through hole 2. The purpose of the circular through hole 2 is to facilitate the threaded connection between the connector 1 and the nozzle 12 and to facilitate the rotation of the connector 1. The other section has a rectangular cross-section, i.e., a rectangular through hole 2. The purpose of the rectangular through hole 2 is to match the dustproof component 6. The shape of the dustproof component 6 matches the rectangular through hole 2. When the dustproof component 6 blocks the through hole 2, the edge of the dustproof component 6 fits against the inner wall of the through hole 2. The inner wall of the circular through hole 2 is provided with a first thread. An anti-clogging component is disposed within the through hole 2.

[0020] The anti-blocking component includes: The first groove 3 is formed in the top of the connector 1. Two fasteners are fixedly connected to the top of the first groove 3. A rotating shaft is provided between the two fasteners, and the two ends of the rotating shaft are rotatably connected to the two fasteners respectively. The dustproof component 6 is located at its upper end within the first groove 3, and its upper end is fixedly connected to the fixing component.

[0021] Also includes: The limiting member 7 is fixedly connected to the first groove 3.

[0022] Also includes: The first magnet 8 is fixedly connected to the lower end of the dustproof component 6; The second magnet 9 is fixedly connected to the bottom of the connector 1, and the second magnet 9 corresponds to the first magnet 8.

[0023] like Figures 1 to 4 As shown, an embodiment of this utility model provides an array-type emission stream soot blower, comprising: The soot blower body 10 has a high-pressure air chamber 11 on its lower surface. Multiple nozzles 12 are spaced at different heights on the side wall of the soot blower body 10. All nozzles 12 are connected to the high-pressure air chamber 11. The nozzles 12 are variable diameter nozzles, also known as Laval nozzles. Each nozzle 12 has a second thread on its exterior.

[0024] The anti-clogging structure described above is connected to the nozzle 12. The first thread inside the connector 1 engages with the second thread outside the nozzle 12, thereby achieving a threaded connection between the connector 1 and the nozzle 12. The air inlet pipe 13 is connected at one end to the high-pressure air chamber 11.

[0025] Also includes: The second groove 4 is formed on the lower surface of the soot blower body 10. The second groove 4 is U-shaped. The high-pressure air chamber 11 is located inside the second groove 4. The second groove 4 is connected to the high-pressure air chamber 11. The depth of the second groove 4 gradually increases from the direction away from the high-pressure air chamber 11 to the direction closer to the high-pressure air chamber 11. Also includes: The third groove 5 is formed on the lower surface of the soot blower body 10. The second groove 4 is U-shaped and is located inside the third groove 5. The third groove 5 is connected to the second groove 4 and cooperates with the air inlet pipe 13.

[0026] When soot blowing is required inside the boiler, the entire device is placed inside the boiler. An external air source is then connected to the end of the air inlet pipe 13 furthest from the soot blower body 10. Air is then introduced into the air inlet pipe 13. The gas in the air inlet pipe 13 first enters the second groove 4. Because the depth of the second groove 4 gradually increases horizontally from the direction away from the high-pressure air chamber 11 towards the direction closer to the high-pressure air chamber 11, the space for gas passage is reduced, thereby increasing the internal pressure of the gas and increasing the gas flow rate. The gas passes through the second groove 4 and enters the high-pressure air chamber 11. Subsequently, the gas passes through the soot blower body. The nozzles 12 on the side wall of the sootblower body 10 are arranged in multiple intervals at the same height. This patent takes eight as an example. If the side wall of the sootblower body 10 is cylindrical, then eight nozzles 12 are arranged at the same height of the sootblower body 10. The spacing between two adjacent nozzles 12 is the same, which can ensure that the gas ejected by each nozzle 12 blows soot onto the boiler at different angles, thereby improving the sootblowing efficiency. At the same time, a single nozzle 12 will generate force when working. Therefore, the nozzles 12 are designed in a circumferential array to counteract the force generated by the air jet on the sootblower body 10.

[0027] When the gas is not ejected from the nozzle 12, the first magnet 8 on the dustproof component 6 engages with the second magnet 9 at the bottom of the connector 1. The first magnet 8 and the second magnet 9 have different magnetic properties and attract each other. The attraction between the first magnet 8 and the second magnet 9 can prevent the dustproof component 6 from shaking when the blower is not in use, and prevent external dust from passing through the connector 1 and entering the nozzle 12. When the gas is ejected from the nozzle 12, the gas exerts a thrust on the dustproof component 6, and the lower end of the dustproof component 6 rotates upward until the dustproof component 6 is completely inserted into the groove. The gas passes through the connector 1 and is ejected outward, and the ejected gas blows away the dust.

[0028] When dust blowing is no longer needed, the dust cover 6 will return to its original position under gravity. At this time, the limiting component 7 comes into contact with the dust cover 6, and the limiting component 7 limits the movement of the dust cover 6, further preventing it from shaking. Through the cooperation of the first magnet 8 and the second magnet 9, as well as the limiting component 7, the stability of the dust cover 6 is improved, preventing external dust from entering the nozzle and reducing damage to the dust blower. The dust cover 6 is made of low-density and high-temperature resistant materials, such as aerogel and titanium alloy.

[0029] Alternatively, eight nozzles 12 can be provided at different heights of the sootblower body 10. For example, eight nozzles 12 can be spaced 20 mm away from the lower surface of the sootblower body 10, eight nozzles 12 can be spaced 37 mm away from the lower surface of the sootblower body 10, and one nozzle 12 can be provided 43 mm away from the lower surface of the sootblower body 10. This allows air to be blown simultaneously from multiple rows of nozzles 12, thus improving the sootblowing efficiency by blowing air onto the boiler at different heights at the same time.

[0030] The nozzle 12 is a variable diameter nozzle 12, so when the gas passes through the nozzle 12, the gas flow rate can be increased, making the gas reach supersonic speed, increasing the impact force of the gas, and improving the soot blowing effect. Through the acceleration of the second groove 4 and the acceleration of the nozzle 12, the gas is accelerated three times, which greatly improves the soot blowing effect of the gas.

[0031] It should be noted that the side wall of the sootblower body 10 can also be a polygonal prism. Taking an octagonal prism as an example, multiple nozzles 12 are provided on each side of the octagonal prism. Each nozzle 12 is at a different height, which can also achieve the sootblowing effect on the boiler. The sootblowing principle is the same as the side wall shape of the sootblower body 101 being cylindrical. The specific working process will not be described in detail here.

[0032] The gas flow rate can be increased to supersonic speed with only the blower body 10 and the air inlet pipe 13. The structure is simple and the manufacturing cost is low.

[0033] A high-pressure gas chamber 11 is formed on the lower surface of the sootblower body 10. The high-pressure gas chamber 11 is cylindrical in shape with a rectangular cross-section. A second groove 4 is formed on the lower surface of the sootblower body 10 and is connected to the high-pressure gas chamber 11. The depth of the second groove 4 gradually increases from the direction away from the high-pressure gas chamber 11 to the direction closer to the high-pressure gas chamber 11. The depth of the second groove 4 at the end closer to the high-pressure gas chamber 11 is less than the depth of the high-pressure gas chamber 11, thus making the cross-sectional shape of the second groove 4 a right-angled triangle. High-pressure gas enters the high-pressure gas chamber 11. Since a nozzle 12 connected to the high-pressure gas chamber 11 is provided on the side wall of the sootblower body 10, after the gas enters the high-pressure gas chamber 11, the gas velocity increases to supersonic speed through the nozzle 12 and then is ejected from the nozzle 12. The ejected gas cleans the boiler.

[0034] A third groove 5 is provided on the lower surface of the sootblower body 10. The third groove 5 is connected to the second groove 4. The cross-sectional shape of the third groove 5 is rectangular, and the outer diameter of the third groove 5 matches the outer diameter of the air inlet pipe 13. Therefore, the third groove 5 facilitates the installation of the air inlet pipe 13. In addition, the depth of the third groove 5 is less than the depth of the second groove 4 near the high-pressure air chamber 11. Therefore, when the air inlet pipe 13 is inserted into the third groove 5, it cannot be pushed upward after contacting the second groove 4, thus achieving a positioning effect for the air inlet pipe 13.

[0035] Because the temperature inside the boiler is too high, the soot blower body 10, nozzle 12 and air inlet pipe 13 are all made of high temperature resistant materials to avoid damage to the entire device caused by the excessive boiler temperature.

[0036] This utility model has the following advantages: 1. By accelerating the gas and increasing its flow rate to supersonic speed, the gas impact force is increased, thus improving the soot blowing effect.

[0037] 2. By providing multiple nozzles 12 at intervals at different heights on the sootblower body 10, soot blowing can be performed on the boiler at different heights simultaneously, thus improving soot blowing efficiency.

[0038] 3. By aligning multiple nozzles 12 at the same height with different directions, and ensuring that the number of nozzles 12 is even, the forces generated by the relatively arranged nozzles 12 can be mutually canceled, thereby reducing the damage to the sootblower body 10 caused by the forces generated by the nozzles 12.

[0039] 4. Only the soot blower body 10 and the air inlet pipe 13 are needed to increase the gas flow rate to supersonic speed. The structure is simple and the manufacturing cost is low.

[0040] 5. The anti-clogging structure can prevent external dust from entering the sootblower, reducing damage to the sootblower.
