Description

Technical Field

[0001] This utility model relates to the technical field of desulfurization towers, specifically to a support structure for an adjustable spray layer height in a desulfurization tower. Background Technology

[0002] Desulfurization towers are key pieces of equipment widely used in industrial flue gas treatment. Their core function is to efficiently remove sulfur dioxide (SO2) from flue gas, thereby significantly reducing industrial emissions' pollution of the atmospheric environment. In existing technologies, desulfurization towers primarily rely on spray devices to generate a large number of fine droplets. These droplets come into full contact with the rising flue gas, achieving the absorption and removal of sulfur dioxide through a gas-liquid mass transfer process. This process involves not only complex physicochemical reactions but is also affected by various operating parameters, such as droplet size, spray density, flue gas flow rate, temperature, and the chemical properties of the absorbent.

[0003] According to Chinese Patent CN120268188A, a desulfurization tower is disclosed, comprising a tower body with an inlet and an outlet, both connected to the interior of the tower body. Inside the tower body are a storage tank, a packing layer, and a first spray pipe with a first nozzle. The outlet is located above the first spray pipe, and the inlet is located between the storage tank and the packing layer. A supply pipe is fixed to the tower body, and the first spray pipe is connected to the supply pipe. A circulation pump is installed on the supply pipe or the first spray pipe. The packing layer includes a first packing layer, a second packing layer, and a third packing layer. The outer edge of the first packing layer is connected to the tower body, and a first central hole is located in its center. The second packing layer has a second central hole in its center. The inner edge of the second packing layer is integrally connected to the inner edge of the first packing layer, and the outer edge of the second packing layer is integrally connected to the edge of the third packing layer. This desulfurization tower adapts to changes in flue gas emissions.

[0004] However, in the operation of existing desulfurization towers, the spray layer height cannot be adjusted, which makes it impossible to flexibly adjust the gas-liquid contact time and absorption efficiency according to changes in operating conditions such as flue gas flow rate and sulfur dioxide concentration, causing inconvenience to users. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problem that, in the process of using existing desulfurization towers, the spray layer of the existing desulfurization towers cannot be adjusted in height, which makes it impossible to flexibly adjust the gas-liquid contact time and absorption efficiency according to changes in operating conditions such as flue gas flow rate and sulfur dioxide concentration, causing inconvenience to users.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] An adjustable support structure for the spray layer of a desulfurization tower includes a desulfurization tower body. An air inlet is fixed to the lower side of the desulfurization tower body, and an air outlet is fixed to the upper side of the desulfurization tower body. A first pipe is fixed to the upper side of the desulfurization tower body. A second pipe is slidably connected to the lower side of the first pipe, and a third pipe is slidably connected to the lower side of the second pipe. A spray plate is fixed to the lower side of the third pipe. The spray plate consists of an mounting plate and an atomizing nozzle. An adjusting threaded rod is movably connected to the spray plate. A sealing threaded seat is fixed to the desulfurization tower body. The adjusting threaded rod is threadedly connected to the sealing threaded seat, forming a spiral lifting mechanism. The height of the spray plate can be adjusted online without stopping the tower. The three layers of telescopic pipes slide synchronously with the spray plate, maintaining a sealed connection at all times.

[0008] As a preferred embodiment of this utility model, a snap-fit ​​plate is fixed to the lower side of the first pipe, snap-fit ​​plates are fixed to both the upper and lower sides of the second pipe, and a snap-fit ​​plate is fixed to the upper side of the third pipe.

[0009] As a preferred technical solution of this utility model, the snap-fit ​​plate of the first pipe slides inside the second pipe, the snap-fit ​​plate of the second pipe slides inside the third pipe, and an assist rod is fixed on the adjusting threaded rod. The snap-fit ​​plate slides inside the adjacent pipe, realizing the extension and retraction of the "pipe in pipe" without the need for an additional guide rail.

[0010] As a preferred embodiment of this utility model, a support plate is fixed to the lower side of the desulfurization tower body, and a control panel is fixed to the side of the desulfurization tower body.

[0011] As a preferred technical solution of this utility model, a heating coil is fixed at the bottom of the desulfurization tower body, and a storage tank is fixed at the back of the desulfurization tower body. A water pump is installed in the storage tank. The heating coil can heat the slurry at the bottom of the tower at a constant temperature to prevent low-temperature crystallization in winter, and can also regulate the internal temperature of the desulfurization tower body. The storage tank integrates a water pump to form a closed-loop circulation. When the machine stops, the slurry in the pipeline is automatically pumped back to avoid freezing and blockage, and to ensure stable operation of the system throughout the year.

[0012] As a preferred embodiment of this utility model, the pipe on the lower side of the storage tank is installed at the bottom of the desulfurization tower body, and the pipe on the upper side of the storage tank is connected to the first pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] Because this utility model has a sliding pipe on the spray plate, the sliding pipe can adapt to the height of the spray plate by extending and retracting up and down, and the spray plate is threaded with an adjusting screw. The user can adjust the height of the spray plate by rotating the adjusting screw, which is convenient for the user. Attached Figure Description

[0025] Example 1

[0026] exist Figure 1-4 This utility model provides a technical solution: an adjustable support structure for the spray layer of a desulfurization tower, including a desulfurization tower body 1, an air inlet 2 fixed to the lower side of the desulfurization tower body 1, an air outlet 3 fixed to the upper side of the desulfurization tower body 1, a first pipe 4 fixed to the upper side of the desulfurization tower body 1, a second pipe 5 slidably connected to the lower side of the first pipe 4, a third pipe 6 slidably connected to the lower side of the second pipe 5, a spray plate 7 fixed to the lower side of the third pipe 6, the spray plate 7 consisting of an mounting plate and an atomizing nozzle, an adjusting threaded rod 8 movably connected to the spray plate 7, a sealing threaded seat 9 fixed to the desulfurization tower body 1, the adjusting threaded rod 8 threadedly connected to the sealing threaded seat 9, rotating the adjusting threaded rod 8, the spray plate 7 moves up and down within the sealing threaded seat 9 along with the third pipe 6, the first pipe 4, the second pipe 5 and the third pipe 6 slide and extend sequentially, realizing stepless adjustment of the spray layer height.

[0027] In one aspect of this embodiment, a snap-fit ​​plate 10 is fixed to the lower side of the first pipe 4, snap-fit ​​plates 10 are fixed to both the upper and lower sides of the second pipe 5, and a snap-fit ​​plate 10 is fixed to the upper side of the third pipe 6. The snap-fit ​​plate 10 of the first pipe 4 slides inside the second pipe 5, and the snap-fit ​​plate 10 of the second pipe 5 slides inside the third pipe 6. An assist rod 11 is fixed to the adjusting threaded rod 8. The snap-fit ​​plates 10 are nested and slide together to provide radial limit for the telescopic section, preventing the pipe from swaying or disengaging during adjustment. The assist rod 11 increases the rotational torque, making the height adjustment operation easier and more accurate.

[0028] In one aspect of this embodiment, a support plate 12 is fixed to the lower side of the desulfurization tower body 1, and a control panel 13 is fixed to the side of the desulfurization tower body 1.

[0029] In one aspect of this embodiment, a heating coil 14 is fixed to the bottom of the desulfurization tower body 1, and a storage tank 15 is fixed to the back of the desulfurization tower body 1. A water pump is installed inside the storage tank 15. The pipe on the lower side of the storage tank 15 is installed at the bottom of the desulfurization tower body 1, and the pipe on the upper side of the storage tank 15 is connected to the first pipe 4. The heating coil 14 heats the liquid accumulated at the bottom of the tower and can control the temperature inside the desulfurization tower body 1 to prevent the slurry from crystallizing and clogging. After being pressurized by the water pump, the absorbent liquid in the storage tank 15 passes through the upper pipe, the first pipe 4, the second pipe 5 and the third pipe 6 in sequence, and is finally sprayed out by the atomizing nozzle of the spray plate 7 to form a circulating spray. When the height is adjusted, the pipes extend and retract synchronously to ensure a continuous supply of absorbent liquid and maintain stable system operation.

[0030] The working principle of this utility model is as follows: The rotating assist rod 11 drives the adjusting threaded rod 8 to rotate within the sealing threaded seat 9, causing the spray plate 7 to rise and fall synchronously with the third pipe 6. The first pipe 4, the second pipe 5, and the third pipe 6 slide and extend through the nested snap-fit ​​plates 10 to adjust the height of the spray layer. The snap-fit ​​plates 10 provide radial limiting to prevent the pipes from swaying or disengaging during adjustment. The heating coil 14 heats the liquid accumulated at the bottom of the tower and controls the temperature inside the desulfurization tower body 1 to prevent slurry crystallization and blockage. The absorbent liquid in the storage tank 15 is pressurized by a water pump and flows sequentially through the upper pipe, the first pipe 4, the second pipe 5, and the third pipe 6, finally being sprayed out by the atomizing nozzles of the spray plate 7 to form a circulating spray. The synchronous extension and retraction of the pipes during height adjustment ensures a continuous supply of absorbent liquid, maintains stable system operation, adapts to different flue gas loads, and improves desulfurization efficiency.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
