Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and in particular to a device for clearing and unblocking ash from a semi-dry desulfurization absorption tower. Background Technology

[0002] Desulfurization absorption towers are tower-type equipment used for desulfurization treatment of industrial waste gas. Initially, they were widely constructed using granite masonry, utilizing the principle of water film desulfurization and dust removal. Later, they were gradually developed into fiberglass reinforced plastic (FRP) structures due to their low cost and ease of processing. Spray towers are another widely used type, particularly suitable for power plant flue gas treatment. Large desulfurization towers need to withstand dynamic loads and are prone to vibration problems, requiring anti-corrosion and anti-wear measures. Wet flue gas desulfurization technology has become the dominant process in thermal power plants due to its high efficiency and wide applicability to various coal types, but it faces challenges such as strong corrosiveness and difficult maintenance, necessitating the selection of anti-corrosion materials that meet requirements for temperature resistance and wear resistance. Desulfurization slurry circulation pumps are prone to failure due to strong abrasiveness, corrosion, and cavitation, requiring repair using wear-resistant and corrosion-resistant materials. During operation, semi-dry desulfurization absorption towers are prone to ash accumulation at the bottom of the tower and within the flue, affecting system stability and desulfurization efficiency.

[0003] However, existing ash removal devices for desulfurization absorption towers can only remove a small amount of ash, and cannot effectively remove and clean large amounts of waste residue and dust. This leads to easy blockage inside the desulfurization absorption tower pipes, affecting the processing efficiency and quality of the desulfurization absorption tower. Utility Model Content

[0004] The main purpose of this utility model is to provide a device for clearing and unblocking ash from a semi-dry desulfurization absorption tower, which can effectively solve the problem of not being able to smoothly clear and clean large amounts of waste residue and dust.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A semi-dry desulfurization absorption tower ash removal and unblocking device includes a desulfurization absorption tower body and an L-shaped bearing shell. An L-shaped flue pipe is installed and fixed inside the L-shaped bearing shell. A bearing mechanism is fixedly connected to the lower left end of the outer surface of the L-shaped bearing shell. A servo motor is installed and fixedly mounted on the upper part of the bearing mechanism. A transmission mechanism is fixedly connected to the lower output end of the servo motor.

[0009] Preferably, the material conveying mechanism includes a drive shaft, the upper end of which is fixedly connected to a conical helical blade, and the lower end of the drive shaft is fixedly connected to the upper end of the outer surface of the driven wheel.

[0010] Preferably, the unblocking mechanism includes several support frames, the upper inner cavity of the several support frames is fixedly connected to a main pipe, the lower part of the main pipe is fixedly connected to several branch pipes at intervals, and the lower part of each of the several branch pipes is fixedly connected to a high-pressure nozzle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a supporting mechanism to support the servo motor, a transmission mechanism to drive the material conveying mechanism to rotate, and a material conveying mechanism to stir and transport impurities blocked in the left side of the L-shaped flue pipe, thus improving the device's practicality.

Furthermore, a sealing mechanism seals the discharge mechanism's inner cavity, enhancing the device's practicality and versatility.

[0015] This invention uses a clockwise rotating conical spiral blade to stir and break up the mixture and impurities blocking the left inner cavity of the L-shaped flue. The mixture and impurities are then transported along the inner cavity of the L-shaped flue to the right inner cavity. Simultaneously, under the high-pressure blowing force of several high-pressure nozzles, the broken impurities transported to the right inner cavity of the L-shaped flue continue to be blown to the right until the mixture and impurities are concentrated and discharged to the outside through the discharge pipe, thus improving the practicality and versatility of the device.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, a semi-dry desulfurization absorption tower ash removal device includes a desulfurization absorption tower body 1 and an L-shaped bearing sleeve 2. An L-shaped flue pipe 3 is installed and fixed inside the L-shaped bearing sleeve 2. A bearing mechanism 4 is fixedly connected to the lower left end of the outer surface of the L-shaped bearing sleeve 2, which can support a servo motor 5. The servo motor 5 is installed and fixedly mounted on the upper part of the bearing mechanism 4. A transmission mechanism 6 is fixedly connected to the lower output end of the servo motor 5, which can drive the material conveying mechanism 7 to rotate. A material conveying mechanism is fixedly connected to the upper right side of the transmission mechanism 6. Mechanism 7 can stir and transport impurities that are blocked in the left side of the L-shaped flue pipe 3. A clearing mechanism 8 is fixedly connected to the upper right side of the outer surface of the L-shaped bearing sleeve 2, which can blow the impurities transported to the right side of the L-shaped flue pipe 3. A discharge mechanism 9 is fixedly connected to the lower right side of the outer surface of the L-shaped bearing sleeve 2, which can facilitate the discharge of impurities blown to the right. A sealing mechanism 10 is threadedly connected to the inner cavity of the discharge mechanism 9, which can facilitate the sealing of the inner cavity of the discharge mechanism 9.

[0023] To achieve the purpose of supporting servo motor 5, please refer to... Figure 2The bearing mechanism 4 includes a bearing plate 41. Tripods 42 are symmetrically fixedly connected to the upper end of the outer surface of the bearing plate 41. This facilitates the connection and fixation of the bearing plate 41 to the left side of the L-shaped bearing housing 2. Both tripods 42 are fixedly connected to the lower left side of the outer surface of the L-shaped bearing housing 2.

[0024] To achieve the purpose of driving the material conveying mechanism 7 to rotate, refer to... Figure 3 The transmission mechanism 6 includes a drive wheel 61, a belt 62 is sleeved on the outside of the drive wheel 61, a driven wheel 63 is sleeved on the right side of the belt 62, and the upper middle part of the outer surface of the drive wheel 61 is fixedly connected to the lower output end of the servo motor 5.

[0025] By driving the servo motor 5, the drive wheel 61 can be started to rotate, which in turn will drive the driven wheel 63 to rotate through the belt 62. This will cause the drive shaft 71 and the conical spiral blade 72 to rotate clockwise, transporting the mixed impurities blocked in the left inner cavity of the L-shaped flue pipe 3 to the right inner cavity of the L-shaped flue pipe 3.

[0026] To achieve the purpose of stirring and conveying the impurities blocking the left side of the L-shaped flue pipe 3, please refer to... Figure 3 The material conveying mechanism 7 includes a drive shaft 71, with a conical spiral blade 72 fixedly connected to the upper end of the drive shaft 71. This blade can easily crush the mixture and impurities that are blocked in the left inner cavity of the L-shaped flue pipe 3 and convey them to the right. The lower end of the drive shaft 71 is fixedly connected to the upper end of the outer surface of the driven wheel 63.

[0027] To achieve the purpose of blowing away impurities delivered to the right inner cavity of the L-shaped flue pipe 3, refer to... Figure 4 The unblocking mechanism 8 includes several support frames 81. The upper inner cavity of the several support frames 81 is fixedly connected to a main flow pipe 82, which can realize the function of conveying high-pressure airflow. The lower part of the main flow pipe 82 is fixedly connected to several branch pipes 83 at intervals. The lower part of each branch pipe 83 is fixedly connected to a high-pressure nozzle 84, which can cooperate with the conical spiral blade 72 to blow and convey the mixed impurities in the right inner cavity of the L-shaped flue pipe 3.

[0028] To facilitate the discharge of impurities blown to the right, see [reference needed]. Figure 4 The discharge mechanism 9 includes a discharge pipe 91. An internally threaded sleeve 92 is fixedly connected to the lower end of the outer surface of the discharge pipe 91, which can realize the threaded transmission with the external thread 103 so that the sealing plug 102 is locked in the inner cavity of the discharge pipe 91.

[0029] To facilitate sealing of the inner cavity of the discharge mechanism 9, please refer to... Figure 4The sealing mechanism 10 includes a limiting cover 101. A sealing plug 102 is fixedly connected to the upper end of the outer surface of the limiting cover 101, which can achieve the function of sealing the inner cavity of the discharge pipe 91. An external thread 103 is provided on the lower part of the outer surface of the sealing plug 102, and the external thread 103 is threadedly connected to the inner cavity of the internal thread sleeve 92.

[0030] It should be noted that the servo motor 5 in this utility model is a Siemens 1FT7. The specific installation method, circuit connection method and control method of the servo motor 5 are all conventional designs, and this utility model will not elaborate on them in detail.

[0031] The working principle of this utility model is as follows: When a bed collapse occurs in the desulfurization absorption tower body 1 during operation, producing mixed substances, impurities will fall downwards along the left inner cavity of the L-shaped flue pipe 3. When impurities accumulate in the left inner cavity of the L-shaped flue pipe 3, the drive servo motor 5 drives the drive wheel 61 to start rotating, which in turn drives the driven wheel 63 to start rotating via the belt 62. This, in turn, drives the conical spiral blade 72 to start rotating clockwise via the transmission shaft 71, thereby stirring the accumulated impurities and conveying them to the right inner cavity of the L-shaped flue pipe 3. At this time, the main flow... The upper left input end of pipe 82 is connected to the output end of a high-pressure blower set up in the outside, so that the impurities transported to the inner cavity of the right side of the L-shaped flue pipe 3 are blown to the right by the high-pressure pulses of several high-pressure nozzles 84. At the same time, by rotating the limit cover 101, the sealing plug 102 is driven to have a threaded drive with the inner cavity of the internal threaded sleeve 92, thereby pulling the sealing plug 102 out of the inner cavity of the discharge pipe 91. At this time, when the impurities blown to the right are transported along the inner cavity of the right side of the L-shaped flue pipe 3, the impurities will be concentrated and discharged to the outside for collection along the inner cavity of the discharge pipe 91.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
