Description

Technical Field

[0001] This utility model relates to the field of flue gas desulfurization technology, specifically to a power plant system optimization device for improving desulfurization efficiency. Background Technology

[0002] There are generally three types of desulfurization methods: pre-combustion, during-combustion, and post-combustion desulfurization. With the development of industry and the improvement of people's living standards, the demand for energy is constantly increasing. Sulfur dioxide in coal-fired flue gas has become the main cause of air pollution. Reducing sulfur dioxide pollution has become the top priority for air pollution control. Many flue gas desulfurization processes have been widely used in industry, and they also have important practical significance for the treatment of exhaust gas from various boilers and incinerators.

[0003] Power plants generate electricity by burning coal. During combustion in coal-fired boilers, various organic and inorganic sulfur compounds in the coal are converted into sulfur oxides, primarily sulfur dioxide. Sulfur dioxide enters the atmosphere and combines with water to form acid rain, which not only severely impacts buildings and crops but also harms human health. Therefore, flue gas desulfurization is a crucial aspect of environmental protection. The main method of flue gas desulfurization is wet desulfurization, which uses limestone slurry as a scrubbing agent to spray and wash the flue gas in a reaction tower, thereby absorbing sulfur dioxide from the flue gas.

[0004] However, currently, there is a lack of structures to slow down the rising rate of flue gas when it enters the desulfurization reaction tower for spraying. This causes the flue gas to rise directly after being transported into the desulfurization tower, resulting in a short desulfurization time and difficulty in directly increasing the height of the desulfurization tower. Consequently, the reaction is prone to incomplete, leading to low desulfurization efficiency. Therefore, this utility model provides a power plant system optimization device for improving desulfurization efficiency to meet people's needs. Utility Model Content

[0005] This invention provides a power plant system optimization device for improving desulfurization efficiency. It can effectively solve the problem mentioned in the background art that there is no structure to slow down the rising rate of flue gas when it enters the desulfurization reaction tower for spraying. This causes the flue gas to rise directly after being transported into the desulfurization tower, resulting in a short desulfurization time and difficulty in directly increasing the height of the desulfurization tower, which in turn easily leads to incomplete reaction and low desulfurization efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power plant system optimization device for improving desulfurization efficiency, comprising a desulfurization tower, wherein an air inlet pipe is fixedly connected to one end of the surface wall of the desulfurization tower, and a waste discharge pipe is fixedly connected to one end of the bottom of the desulfurization tower;

[0007] A support frame is fixedly installed at the bottom of the desulfurization tower. A lower mounting circular plate is fixedly installed at the top of the support frame. A connecting frame is fixedly installed at the edge of the top of the lower mounting circular plate. An upper mounting circular plate is fixedly installed at the top of the connecting frame. Left-inclined guide holes are equidistantly opened in the middle of the lower mounting circular plate. Right-inclined guide holes are equidistantly opened in the middle of the upper mounting circular plate.

[0008] Preferably, the edges of the lower mounting plate and the upper mounting plate are in close contact with the inner wall of the desulfurization tower, and the bottom horizontal plane of the lower mounting plate is higher than the top horizontal plane of the air inlet pipe.

[0009] Preferably, a dust removal box is fixedly installed at one end of the air intake pipe, a positioning plate is fixedly installed at the bottom of the dust removal box, and a dust filter plate is embedded in the middle of the dust removal box.

[0010] The top of the dust filter plate is fixedly connected to a fitting long plate, and an operating handle is fixedly installed at the middle of the top of the fitting long plate. A sealing gasket is fixedly fitted at the top of the impurity removal box at the corresponding position of the dust filter plate. A connecting gas pipe is fixedly connected to the middle end of the impurity removal box away from the desulfurization tower.

[0011] Preferably, the positioning plate has a positioning groove at the top center, the bottom end of the dust filter plate is movably embedded in the positioning groove, the top of the dust filter plate is movably extended through the top of the dust removal box, and the bottom end of the fitting long plate is tightly pressed against the top of the sealing gasket.

[0012] Preferably, fixed boxes are symmetrically fixedly installed at both ends of the top of the impurity removal box, and a movable rod is movably installed through the middle of each of the two fixed boxes. A compression spring is sleeved in the middle of the movable rod, a trapezoidal limiting and pressing block is fixedly connected to one end of the movable rod, and a protrusion is fixedly connected to the other end of the movable rod.

[0013] Preferably, the two ends of the compression spring are connected to the inner wall of the fixed box and the trapezoidal limiting and pressing block, respectively. The bottom end of the trapezoidal limiting and pressing block is in close contact with the top end of the fitting long plate, and the edge of the trapezoidal limiting and pressing block is in contact with the side wall of the fixed box.

[0014] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0015] 1. The system is equipped with a support frame, a lower mounting plate, a connecting frame, an upper mounting plate, a left-inclined guide hole, and a right-inclined guide hole. The support frame and connecting frame position the lower and upper mounting plates, intercepting them in the path of the rising flue gas. Simultaneously, the left and right-inclined guide holes guide the flue gas, causing it to travel at an angle during the rising spray desulfurization process. This angled flow slows down the flow rate of the flue gas, thus extending the desulfurization reaction time inside the desulfurization tower without needing to raise it. This ensures the flue gas reacts fully and effectively improves the overall desulfurization efficiency.

[0016] 2. Equipped with a dust removal box, positioning plate, dust filter plate, fitting plate, operating handle, and sealing gasket, the dust removal box and dust filter plate work together to pre-treat the flue gas entering the desulfurization tower, filtering and intercepting large particulate impurities in the flue gas. This prevents large particulate impurities from entering the desulfurization tower with the flue gas and causing blockage or damage to internal spray desulfurization equipment. At the same time, the positioning plate positions the dust filter plate, making its installation more convenient and quick, while the sealing gasket improves the sealing between the fitting plate and the dust removal box, preventing air leakage.

[0017] 3. Equipped with a fixed box, movable rod, compression spring, trapezoidal limiting clamping block, and protrusion, the trapezoidal limiting clamping block clamps the long plate to be attached, replacing bolts and other fixing structures, thus improving the stability of the dust filter plate. After pressurization, the long plate and sealing gasket are more tightly fitted. The movable rod and compression spring allow for quick adjustment of the position of the trapezoidal limiting clamping block, making operation convenient and greatly facilitating the installation and removal of the dust filter plate for the staff.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figure 1-4 As shown, this utility model provides a technical solution, a power plant system optimization device for improving desulfurization efficiency, including a desulfurization tower 1, an air inlet pipe 2 fixedly connected to one end of the surface wall of the desulfurization tower 1, and a waste discharge pipe 3 fixedly connected to one end of the bottom of the desulfurization tower 1.

[0027] A support frame 4 is fixedly installed at the bottom of the desulfurization tower 1. A lower mounting circular plate 5 is fixedly installed at the top of the support frame 4. A connecting frame 6 is fixedly installed at the edge of the top of the lower mounting circular plate 5. An upper mounting circular plate 7 is fixedly installed at the top of the connecting frame 6. The edges of the lower mounting circular plate 5 and the upper mounting circular plate 7 are tightly fitted to the inner wall of the desulfurization tower 1. The bottom horizontal plane of the lower mounting circular plate 5 is higher than the top horizontal plane of the air inlet pipe 2. Left-inclined guide holes 8 are equidistantly opened in the middle of the lower mounting circular plate 5, and right-inclined guide holes 9 are equidistantly opened in the middle of the upper mounting circular plate 7. The support frame 4 and the connecting frame 6 serve to position and install the lower mounting circular plate 5 and the upper mounting circular plate 7, intercepting them in the path of the rising flue gas. At the same time, the left inclined guide hole 8 and the right inclined guide hole 9 guide the flue gas, causing the flue gas to travel at an angle in the rising spray desulfurization path. The inclined guide slows down the flow rate of the flue gas, thereby extending the desulfurization reaction time of the flue gas inside the desulfurization tower 1 without increasing the height of the desulfurization tower 1, allowing the flue gas to react fully and effectively improving the overall desulfurization efficiency.

[0028] A dust removal box 10 is fixedly installed at one end of the air intake pipe 2. A positioning plate 11 is fixedly installed at the bottom of the dust removal box 10. A dust filter plate 12 is embedded in the middle of the dust removal box 10. A positioning groove is opened at the top center of the positioning plate 11. The bottom end of the dust filter plate 12 is movably embedded in the positioning groove.

[0029] The top of the dust filter plate 12 is fixedly connected to a fitting long plate 13, and an operating handle 14 is fixedly installed in the middle of the top of the fitting long plate 13. A sealing gasket 15 is fixedly fitted to the top of the impurity removal box 10 at the corresponding position of the dust filter plate 12. A connecting gas pipe 16 is fixedly connected to the middle of the impurity removal box 10 away from the desulfurization tower 1. The top of the dust filter plate 12 moves through the top of the impurity removal box 10, and the bottom of the fitting long plate 13 is pressed tightly against the top of the sealing gasket 15. The impurity removal box 10 and the dust filter plate 12 cooperate to pre-treat the flue gas entering the desulfurization tower 1, filter and intercept large particulate impurities in the flue gas, and prevent large particulate impurities from entering the desulfurization tower 1 with the flue gas and causing blockage and damage to the internal spray desulfurization equipment. At the same time, the positioning plate 11 is used to position the dust filter plate 12, making its installation more convenient and quick. The sealing gasket 15 improves the sealing between the fitting long plate 13 and the impurity removal box 10 to prevent air leakage.

[0030] Fixed boxes 17 are symmetrically fixed at both ends of the top of the impurity removal box 10. A movable rod 18 is movably installed through the middle of each fixed box 17. A compression spring 19 is sleeved in the middle of the movable rod 18. A trapezoidal limiting and clamping block 20 is fixedly connected to one end of the movable rod 18, and a protrusion 21 is fixedly connected to the other end. The two ends of the compression spring 19 are respectively connected to the inner wall of the fixed box 17 and the trapezoidal limiting and clamping block 20. The bottom end of the trapezoidal limiting and clamping block 20 is tightly attached to the top end of the fitting long plate 13. The edge is attached to the side wall of the fixed box 17. The trapezoidal limiting and pressing block 20 is used to press and fix the attached long plate 13, replacing bolts and other fixing structures, which improves the stability of the dust filter plate 12. After pressure is applied, the attached long plate 13 and the sealing gasket 15 are more tightly attached. The position of the trapezoidal limiting and pressing block 20 can be quickly adjusted by the movable rod 18 and the compression spring 19. The operation is convenient and provides great convenience for the staff to install and disassemble the dust filter plate 12, and facilitates the cleaning of the dust filter plate 12.

[0031] The working principle and usage process of this utility model are as follows: First, the lower mounting circular plate 5 and the upper mounting circular plate 7 are fixedly installed inside the desulfurization tower 1 using the support frame 4 and the connecting frame 6, so that the edges of the lower mounting circular plate 5 and the upper mounting circular plate 7 are in close contact with the inner wall of the desulfurization tower 1. The flue gas generated by the power plant enters the interior of the impurity removal box 10 through the connecting gas pipe 16. The dust filter plate 12 intercepts the flue gas in the path of flue gas flow, and plays a filtering role in the flue gas, intercepting large particulate impurities in the flue gas. The filtered flue gas enters the interior of the desulfurization tower 1 through the air inlet pipe 2 for spray desulfurization operation.

[0032] The flue gas flows upward inside the desulfurization tower 1. The lower circular plate 5 and the upper circular plate 7 intercept the rising flue gas in the path of the flue gas. The flue gas is guided by the left inclined guide hole 8 and the right inclined guide hole 9, so that the flue gas first flows to the left and then flows to the right. The inclined flow reduces the impact force of the rising flue gas, thereby reducing the rising rate of the flue gas. This allows the flue gas to be sprayed and reacted inside the desulfurization tower 1 for a longer time, preventing the flue gas from being discharged upward before it has fully reacted, and improving the overall desulfurization efficiency of the flue gas.

[0033] The dust filter plate 12 intercepts particulate impurities for a long time, and the particulate impurities gradually accumulate inside the impurity removal box 10, causing blockage. The staff needs to clean it regularly. During cleaning, the movable rod 18 is pulled outward by the protrusion 21, the compression spring 19 is compressed, and the trapezoidal limiting and pressing block 20 gradually moves away from the top of the bonding plate 13 and no longer limits and presses it. The staff uses the operating handle 14 to pull the bonding plate 13 and the dust filter plate 12 upward to clean the dust filter plate 12. After cleaning, the dust filter plate 12 is reinserted from the top of the impurity removal box 10, so that the bottom end of the dust filter plate 12 is inserted into the positioning groove at the top of the positioning plate 11. The bonding plate 13 is tightly fitted with the sealing gasket 15. The movable rod 18 is released, and under the action of the compression spring 19 returning to its original extension, the trapezoidal limiting and pressing block 20 is pushed back onto the top of the bonding plate 13, which plays a role in pressing and stabilizing the bonding plate 13 and the dust filter plate 12.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
