Description

Technical Field

[0001] This utility model belongs to the field of desulfurization reactors, specifically relating to a desulfurization reactor that facilitates the replacement of desulfurizing agents. Background Technology

[0002] With the rapid development of industrial production, flue gas desulfurization technology has become increasingly important in the field of environmental protection. Dry desulfurization technology is widely used in the flue gas treatment of small and medium-sized boilers, kilns and other equipment due to its advantages such as simple operation and no wastewater generation. Desulfurization reactors are industrial equipment used to remove sulfides from gases or liquids and are widely used in petroleum refining, natural gas processing, chemical industry, environmental protection and other fields.

[0003] Traditional dry desulfurization reactors typically use a fixed desulfurizing agent packing layer. When the desulfurizing agent becomes ineffective, the reactor needs to be shut down and disassembled for replacement, resulting in reduced production efficiency and increased maintenance costs. Therefore, a desulfurization reactor that facilitates desulfurizing agent replacement needs to be designed to overcome these technical shortcomings. Utility Model Content

This reactor aims to solve the technical problem that under the existing technology, when the desulfurizing agent fails, it is necessary to shut down the machine and disassemble the reactor for replacement, which leads to reduced production efficiency and increased maintenance costs.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a desulfurization reactor that facilitates the replacement of desulfurizing agents. The reactor includes a liquid desulfurization tank, a horizontal solid desulfurization box at the top of the liquid desulfurization tank, two rectangular mounting boxes inside the horizontal solid desulfurization box, a detachable dry desulfurization component inside the rectangular mounting box, rotatable rectangular sealing plates at both ends of the rectangular mounting box, and a rotating mechanism for rotating the rectangular sealing plates on the outside of the horizontal solid desulfurization box.

[0025] This specific embodiment is a desulfurization reactor that facilitates the replacement of the desulfurizing agent, and its structural schematic diagram is shown below. Figures 1-8 As shown, the reactor includes a liquid desulfurization tank 1, a horizontal solid desulfurization box 2 is provided on the top of the liquid desulfurization tank 1, two rectangular mounting boxes 7 are provided inside the horizontal solid desulfurization box 2, a detachable dry desulfurization component is provided inside the rectangular mounting box 7, a rotatable rectangular sealing plate 8 is provided at both ends of the rectangular mounting box 7, and a rotating mechanism for rotating the rectangular sealing plate 8 is provided on the outside of the horizontal solid desulfurization box 2.

[0026] A vertical sealing plate 6 is provided at the bottom of the rectangular mounting box 7. The vertical sealing plate 6 is located inside the horizontal solid desulfurization box 2 and is slidably connected to the horizontal solid desulfurization box 2. An L-shaped mounting plate 3 is fixed at the bottom of the horizontal solid desulfurization box 2. Vertical hydraulic cylinders 5 are fixed on both sides inside the L-shaped mounting plate 3. The output end of the vertical hydraulic cylinder 5 is connected to the vertical sealing plate 6. Through the operation of the vertical hydraulic cylinder 5, the vertical sealing plate 6 can be vertically raised and lowered inside the horizontal solid desulfurization box 2. When the vertical sealing plate 6 is raised and lowered to the bottom surface of the rectangular mounting box 7, it can block the flow of gas, thereby causing the gas to have to pass through the inside of the rectangular mounting box 7 before it can flow inside the horizontal solid desulfurization box 2.

[0027] The dry desulfurization assembly includes a U-shaped mounting box 10, a rectangular mounting box 7 with the U-shaped mounting box 10 slidably connected inside, a plurality of rectangular desulfurization plates 11 evenly distributed inside the U-shaped mounting box 10, and a rectangular cover plate 4 bolted to one end of the U-shaped mounting box 10. The rectangular cover plate 4 penetrates the interior of the transverse solid desulfurization box 2 and is slidably connected to the transverse solid desulfurization box 2.

[0028] A vertical light rod 13 is slidably connected inside the rectangular cover plate 4. A vertical pull plate 12 is fixed to the top of the vertical light rod 13. A vertical rigid spring 14 is provided between the rectangular cover plate 4 and the vertical pull plate 12 and outside the vertical light rod 13. A dovetail fixing block 15 is also slidably connected inside the rectangular cover plate 4. A circular limiting hole is opened inside the dovetail fixing block 15 to fit the vertical light rod 13 with a clearance. The dovetail fixing block 15 is located on the side close to the horizontal solid desulfurization box 2 and is fixedly connected to the horizontal solid desulfurization box 2.

[0029] The rectangular cover plate 4 has a dovetail groove inside. The dovetail fixing block 15 is located inside the dovetail groove and is slidably connected to the rectangular cover plate 4 through the dovetail groove. The dovetail groove allows the rectangular cover plate 4 to be installed on the outside of the dovetail fixing block 15. After the vertical light rod 13 enters the inside of the dovetail fixing block 15, it can restrict the movement of the rectangular cover plate 4 on the outside of the dovetail fixing block 15.

[0030] Here, the vertical pull plate 12 is pulled upwards. The pulling of the vertical pull plate 12 allows the vertical smooth rod 13 to slide vertically inside the L-shaped mounting plate 3. The pulling of the vertical pull plate 12 causes the vertical rigid spring 14 to deform under force. After the vertical smooth rod 13 moves out of the dovetail fixing block 15, the position restriction of the vertical smooth rod 13 on the rectangular cover plate 4 is released, allowing the rectangular cover plate 4 to slide on the outside of the dovetail fixing block 15. This allows the U-shaped mounting box 10 and the rectangular desulfurization plate 11 to move out of the interior of the transverse solid desulfurization box 2, so as to facilitate the subsequent replacement of the rectangular desulfurization plate 11.

[0031] The rotating mechanism includes a double-output shaft cylinder 18, which is fixed to the outside of the transverse solid desulfurization box 2. The output end of the double-output shaft cylinder 18 is rotatably connected to a rectangular rotating column 16 via a pin. The end of the rectangular rotating column 16 away from the double-output shaft cylinder 18 is rotatably connected to a rectangular transmission column 17 via a pin. The interior of the end of the rectangular transmission column 17 away from the rectangular rotating column 16 is fixed with a longitudinal rotating shaft 9. The longitudinal rotating shaft 9 passes through the interior of the rectangular sealing plate 8 and is fixedly connected to the rectangular sealing plate 8.

[0032] The longitudinal rotating shaft 9 passes through the interior of the transverse solid desulfurization box 2 and is rotatably connected to the transverse solid desulfurization box 2 through a bearing, thereby enabling the longitudinal rotating shaft 9 to rotate inside the transverse solid desulfurization box 2. The rotation of the longitudinal rotating shaft 9 enables the rectangular sealing plate 8 to rotate.

[0033] Here, the operation of the dual-output cylinder 18 enables the two rectangular rotating columns 16 to move. Through the setting of the rectangular transmission column 17, the longitudinal rotating shaft 9 can rotate inside the transverse solid desulfurization box 2. The rotation of the longitudinal rotating shaft 9 causes the rectangular sealing plate 8 to rotate, thereby allowing the two rectangular sealing plates 8 to fit against the two ends of the rectangular mounting box 7, thus restricting the flow of gas inside the rectangular mounting box 7. When the rectangular mounting box 7 is isolated from the gas inside the transverse solid desulfurization box 2, the dry desulfurization component inside the rectangular mounting box 7 can be disassembled from the transverse solid desulfurization box 2. The vertical hydraulic cylinder 5 at the bottom of the corresponding rectangular mounting box 7 is operated, allowing the vertical sealing plate 6 to slide inside the transverse solid desulfurization box 2, and creating a gap between the vertical sealing plate 6 and the rectangular mounting box 7 to facilitate the flow of gas inside the transverse solid desulfurization box 2, so that the rectangular desulfurization plate 11 can be replaced and maintained without stopping the machine.

[0034] By setting up two sets of switchable dry desulfurization components, along with a rotatable rectangular sealing plate 8, the other set can continue to work normally when one set of dry desulfurization components is replaced, ensuring uninterrupted desulfurization process and improving production efficiency. The design of the rectangular sealing plate 8 ensures that the gas passage inside the rectangular mounting box 7 remains closed during the switching process, preventing the leakage of untreated flue gas and ensuring desulfurization efficiency and environmental compliance.

[0035] Working principle: When the rectangular desulfurization plate 11 needs to be disassembled, the operation of the double-outlet cylinder 18 enables the two rectangular rotating columns 16 to move. Through the setting of the rectangular transmission column 17, the longitudinal rotating shaft 9 can rotate inside the transverse solid desulfurization box 2. The rotation of the longitudinal rotating shaft 9 enables the rectangular sealing plate 8 to rotate, thereby allowing the two rectangular sealing plates 8 to fit against the two ends of the rectangular mounting box 7, thus restricting the flow of gas inside the rectangular mounting box 7. When the rectangular mounting box 7 is isolated from the gas inside the transverse solid desulfurization box 2, the dry desulfurization component inside the rectangular mounting box 7 can be disassembled from the transverse solid desulfurization box 2. The vertical hydraulic cylinder 5 at the bottom of the rectangular mounting box 7 operates, allowing the vertical sealing plate 6 to slide inside the transverse solid desulfurization box 2, creating a gap between the vertical sealing plate 6 and the rectangular mounting box 7 to facilitate the flow of gas inside the transverse solid desulfurization box 2, so that the rectangular desulfurization plate 11 can be replaced and maintained without stopping the machine.

[0036] Pulling the vertical pull plate 12 upwards allows the vertical smooth rod 13 to slide vertically inside the L-shaped mounting plate 3. Pulling the vertical pull plate 12 causes the vertical rigid spring 14 to deform under force. When the vertical smooth rod 13 moves out of the dovetail fixing block 15, the position restriction of the vertical smooth rod 13 on the rectangular cover plate 4 is released, allowing the rectangular cover plate 4 to slide on the outside of the dovetail fixing block 15. This allows the U-shaped mounting box 10 and the rectangular desulfurization plate 11 to move out of the interior of the transverse solid desulfurization box 2, facilitating the subsequent replacement of the rectangular desulfurization plate 11.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
