Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization machines, and particularly relates to a flue gas desulfurization machine. Background Art

[0002] Desulfurization generally refers to the process of removing sulfur from fuel before combustion and removing sulfur from flue gas before emission, which is one of the important technical measures for preventing and controlling air pollution. Generally, there are three desulfurization methods: desulfurization before combustion, during combustion, and after combustion. With the development of industry and the improvement of people's living standards, the demand for energy is also increasing continuously. SO2 in coal-fired flue gas has become the main cause of air pollution. Reducing SO2 pollution has become the top priority of current air environment governance. Many flue gas desulfurization processes have been widely used in industry, and they also have important practical significance for the treatment of tail gas from various boilers and incinerators.

[0003] For example, the Chinese patent with the publication number CN218221841U proposes a flue gas desulfurization mechanism. This patent is equipped with a first spray pipe and three second spray pipes. The first nozzles on the first spray pipe are one-way countercurrent nozzles, and the second nozzles of the following three second spray pipes adopt two-way countercurrent and concurrent nozzles. In this way, the four-layer spray achieves the effect of seven layers, greatly improving the desulfurization efficiency. Thus, there is no need to increase the spray layer components in the desulfurization tower, and further ensure that the specific surface area of the slurry droplets will not decrease significantly to ensure the desulfurization effect of the spray layer. However, in this solution, since there may be spray dead angles when the spray head sprays water mist to desulfurize the flue gas, the reaction between the flue gas and the sprayed liquid medicine is not sufficient, affecting the purification effect of the flue gas.

On the outer circumferential wall surface of the first desulfurization chamber 3, a flue gas inlet pipe 4 is fixedly installed. On the outer circumferential wall surface of the first desulfurization chamber 3, two fixed ears 5 are fixedly installed. On the top surface of the fixed ear 5, a threaded groove 8 is opened. On the top surface of the first desulfurization chamber 3, a second desulfurization chamber 6 is arranged. On the outer circumferential wall surface of the second desulfurization chamber 6, an installation ear 7 is fixedly installed. On the top surface of the installation ear 7, a second threaded hole 32 is opened. Threadedly connected to the inner circumferential wall surface of the second threaded hole 32 is a bolt 9, and the outer circumferential wall surface of the bolt 9 is threadedly connected to the inner circumferential wall surface of the threaded groove 8. On the top surface of the second desulfurization chamber 6, a rotation hole 10 is opened. Rotatably sleeved on the inner circumferential wall surface of the rotation hole 10 is a water inlet pipe 11. Fixedly sleeved on the outer circumferential wall surface of the water inlet pipe 11 is a water delivery pipe 12, and the water delivery pipe 12 is a flexible pipe. On the top surface of the workbench 1, a liquid storage tank 13 is fixedly installed. On the top surface of the liquid storage tank 13, an installation hole 14 is opened. The inner circumferential wall surface of the installation hole 14 is fixedly sleeved with the outer circumferential wall surface of the water delivery pipe 12. Inside the liquid storage tank 13, a water pump 15 is arranged, and the water pump 15 is electrically connected to the PLC controller 2. The water outlet of the water pump 15 is fixedly sleeved with the inner circumferential wall surface of the water delivery pipe 12. On the outer circumferential wall surface of the water inlet pipe 11, two rotating rods 16 are fixedly installed. On the outer circumferential wall surface of the water inlet pipe 11, a plurality of spray holes 28 are opened. Fixedly installed on the inner circumferential wall surface of the spray hole 28 is a spray head 29. By providing the spray head 29, when the staff needs to desulfurize the flue gas, at this time, the staff rotates the bolt 9 to make the bolt 9 screw into the threaded groove 8 and the second threaded hole 32 to limit and install the first desulfurization chamber 3 and the second desulfurization chamber 6.

The inner ring of the sealing bearing 27 is fixedly sleeved on the outer circular wall surface of the water inlet pipe 11. By providing the sealing bearing 27, when the water inlet pipe 11 rotates back and forth, at this time, the sealing bearing 27 makes the water inlet pipe 11 more stable when rotating, avoiding shaking and falling off. A positioning hole 22 is opened on the top surface of the rotating rod 16. A sliding column 23 is movably sleeved on the inner circular wall surface of the positioning hole 22. Two limiting grooves 24 are opened on the top surface of the second desulfurization bin 6. The inside of the limiting grooves 24 is movably sleeved with the sliding column 23. When the staff swings the rotating rod 16 back and forth, at this time, the rotating rod 16 is limited by the sliding of the sliding column 23 in the limiting grooves 24, preventing the rotating rod 16 from swinging with a large amplitude and causing the water delivery pipe 12 to break free and fall off. A sealing groove 31 is opened on the top surface of the first desulfurization bin 3. A sealing ring 30 is fixedly installed on the bottom surface of the second desulfurization bin 6. The sealing ring 30 is movably sleeved in the inside of the sealing groove 31. When the staff installs the first desulfurization bin 3 and the second desulfurization bin 6, at this time, the installation effect of the first desulfurization bin 3 and the second desulfurization bin 6 is better by the sealing ring 30 being snapped into the sealing groove 31, avoiding gaps between the first desulfurization bin 3 and the second desulfurization bin 6 and causing flue gas to be discharged from the gaps.

[0026] Embodiment 3

[0027] Based on the above Embodiment 1 or 2, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a sliding groove 17 is opened on the outer circular wall surface of the first desulfurization bin 3. An installation cover 19 is movably sleeved on the inner circular wall surface of the sliding groove 17. A discharge hole 18 is opened at one end inside the sliding groove 17. One end of the installation cover 19 is fixedly installed with a rubber block 20. The outer circular wall surface of the rubber block 20 is movably sleeved in the inner circular wall surface of the discharge hole 18. When the staff finishes spray desulfurization of the flue gas input into the first desulfurization bin 3, at this time, the staff slides the installation cover 19 out of the sliding groove 17 and pulls out the rubber block 20 from the discharge hole 18 to discharge the desulfurized gas in the first desulfurization bin 3 and the second desulfurization bin 6. One end of the installation cover 19 is fixedly installed with a handle 33. The handle 33 facilitates the staff to place and take out the installation cover 19. A storage battery 21 is fixedly installed on one side of the workbench 1. The storage battery 21 is electrically connected to the PLC controller 2. The storage battery 21 is electrically connected to the water pump 15.

[0028] Working principle: Please refer to Figures 1 - 5As shown, through the provided spray nozzles 29, when the staff needs to desulfurize the flue gas, at this time, the staff turns the bolt 9 so that the bolt 9 is screwed into the thread groove 8 and the second threaded hole 32 to limit the installation of the first desulfurization chamber 3 and the second desulfurization chamber 6. Then, the staff inputs the flue gas into the first desulfurization chamber 3 through the smoke inlet pipe 4. At this time, the staff turns on the water pump 15 through the PLC controller 2. After the water pump 15 pumps water, the liquid medicine in the liquid storage tank 13 is pumped into the water delivery pipe 12. Then, the liquid medicine passes through the water delivery pipe 12 and is input into the water inlet pipe 11. Thus, the liquid medicine entering the water inlet pipe 11 is sprayed out from multiple spray nozzles 29 to spray the flue gas in the first desulfurization chamber 3 and the second desulfurization chamber 6. At this time, the staff swings the rotating rod 16 back and forth to make the water inlet pipe 11 rotate back and forth. Then, the spray nozzles 29 swing back and forth to fully spray the inside of the first desulfurization chamber 3 and the second desulfurization chamber 6, thereby achieving the effect of spraying and desulfurizing the flue gas and avoiding the existence of spraying dead corners, which may cause insufficient reaction between the flue gas and the sprayed liquid medicine and affect the purification effect of the flue gas.

[0029] Through the provided sealing bearing 27, when the water inlet pipe 11 rotates back and forth, at this time, the sealing bearing 27 makes the water inlet pipe 11 more stable during rotation, avoiding shaking and falling off. When the staff swings the rotating rod 16 back and forth, at this time, the sliding column 23 slides in the limit groove 24 to limit the rotating rod 16, preventing the rotating rod 16 from swinging with a large amplitude and causing the water delivery pipe 12 to break free and fall off. When the staff installs the first desulfurization chamber 3 and the second desulfurization chamber 6, at this time, the sealing ring 30 is snapped into the sealing groove 31 to make the installation effect of the first desulfurization chamber 3 and the second desulfurization chamber 6 better, avoiding the existence of gaps between the first desulfurization chamber 3 and the second desulfurization chamber 6 and causing the flue gas to escape from the gaps. When the staff finishes spraying and desulfurizing the flue gas input into the first desulfurization chamber 3, at this time, the installation cover 19 slides out from the sliding groove 17 and the rubber block 20 is pulled out from the discharge hole 18 to discharge the desulfurized gas in the first desulfurization chamber 3 and the second desulfurization chamber 6. The handle 33 facilitates the staff to place and remove the installation cover 19.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
