Technical Field
[0001] This utility model relates to the technical field of flue gas desulfurization absorption towers, specifically a flue gas desulfurization absorption tower. Background Technology
[0002] As people have become aware of the serious pollution caused by sulfides to the atmosphere, large amounts of sulfide flue gas are easily generated during industrial production processes. Direct emissions cause serious environmental pollution, necessitating the use of desulfurization absorption towers to desulfurize the sulfides in the flue gas.
[0003] Most existing flue gas desulfurization absorption towers treat flue gas by spraying liquid through nozzles. However, there are often dead zones when spraying liquid through nozzles, which means that some flue gas cannot be desulfurized. This affects the desulfurization effect and efficiency, and makes it inconvenient for staff to use. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a flue gas desulfurization absorption tower, which solves the problem mentioned in the background art that most existing flue gas desulfurization absorption towers treat flue gas by spraying liquid through nozzles. However, when the nozzles spray liquid, there are often dead zones, which means that some flue gas cannot be desulfurized. This affects the desulfurization effect and efficiency of the flue gas, and makes it inconvenient for staff to use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a flue gas desulfurization absorption tower, comprising a reaction tower, an air inlet pipe fixedly connected to the lower left side of the reaction tower, support legs fixedly connected around the bottom of the reaction tower, a drain pipe fixedly connected to the bottom of the reaction tower, a drain valve provided on the surface of the drain pipe, an air outlet pipe fixedly connected to the top of the reaction tower, a suction pump fixedly connected to the right side of the reaction tower, a suction pipe fixedly connected to the bottom of the suction pump, a delivery pipe fixedly connected to the top of the suction pump, a distribution pipe fixedly connected to the left end of the delivery pipe, an atomizing nozzle fixedly connected to the bottom of the distribution pipe, a baffle plate fixedly connected to the upper interior of the reaction tower, a vent hole provided at the top of the baffle plate, a filter screen fixedly connected inside the vent hole, and a flow guide hood fixedly connected to the middle interior of the reaction tower.

This ensures that the flue gas is covered only by the liquid sprayed from the atomizing nozzles, allowing the liquid to fully contact the flue gas and avoiding dead zones. This improves the desulfurization effect of the flue gas, enhances the desulfurization efficiency, and makes it easier for staff to use.
[0008] Preferably, there are several atomizing nozzles, which are arranged in a ring array at the bottom of the liquid distribution tube, and the positions of the several atomizing nozzles are directly above the positions of the several vent holes.
[0009] Preferably, there are several filters, the diameter of which is the same as the inner wall diameter of the several vent holes, and the filters are located inside the several vent holes respectively.
[0010] Preferably, the inner wall of the fairing is a frustum shape that is narrower at the top and wider at the bottom, and the top of the fairing is in close contact with the bottom of the spoiler.
[0011] By adopting the above technical solution, and by setting up a flow guide hood, baffles, and other components in conjunction with a filter screen, the flow guide hood can gather the flue gas in the reaction tower and quickly guide the flue gas to the baffles, allowing it to pass through the baffles quickly and have particulate matter in the flue gas filtered out by the filter screen, thereby improving work efficiency and making it more convenient for staff to use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Referring to Figures 1-5, a flue gas desulfurization absorption tower includes a reaction tower 1. An inlet pipe 2 is fixedly connected to the lower left side of the reaction tower 1. Support legs 3 are fixedly connected to the bottom of the reaction tower 1 around its perimeter. A drain pipe 4 is fixedly connected to the bottom of the reaction tower 1, and a drain valve 5 is installed on the surface of the drain pipe 4. An outlet pipe 6 is fixedly connected to the top of the reaction tower 1. A suction pump 7 is fixedly connected to the right side of the reaction tower 1. A suction pipe 8 is fixedly connected to the bottom of the suction pump 7, and a delivery pipe 9 is fixedly connected to the top of the suction pump 7. The left end of the delivery pipe 9 penetrates the right wall of the reaction tower 1 and extends to the upper interior of the reaction tower 1. A distributor pipe 10 is fixedly connected to the left end of the delivery pipe 9, and an atomizing device is fixedly connected to the bottom of the distributor pipe 10. There are several atomizing nozzles 11 arranged in a ring array at the bottom of the liquid distribution pipe 10, and the positions of the several atomizing nozzles 11 are directly above the positions of several vent holes 13. A baffle plate 12 is fixedly connected to the upper side of the interior of the reaction tower 1. A vent hole 13 is opened on the top of the baffle plate 12. There are several vent holes 13 arranged in a ring array on the surface of the baffle plate 12. The vent holes 13 all penetrate the inner wall of the baffle plate 12, and the spacing between the vent holes 13 is the same. A filter screen 14 is fixedly connected inside the vent hole 13. A flow guide shroud 15 is fixedly connected to the middle side of the interior of the reaction tower 1.
[0026] Working principle: During use, the operator places the suction pipe 8 into the pre-prepared treatment liquid and starts the suction pump 7. The suction pump 7 delivers the reaction liquid to the distribution pipe 10 through the delivery pipe 9. The distribution pipe 10 then atomizes and sprays the reaction liquid towards the vent 13 through the atomizing nozzle 11. At this time, the operator introduces the flue gas to be treated into the reaction tower 1 through the air inlet pipe 2. The flue gas entering the reaction tower 1 is gathered by the guide hood 15 and quickly guided to the baffle plate 12. The baffle plate 12 can block and gather the flue gas entering the reaction tower 1, so that it can only be discharged through the vent 13 and can only be covered by the liquid sprayed by the atomizing nozzle 11, so that the liquid and flue gas can fully contact each other and avoid dead zones. The operator can discharge the waste liquid inside the reaction tower 1 through the drain pipe 4 by opening the drain valve 5, thereby improving the desulfurization effect of the flue gas, enhancing the desulfurization efficiency, and making it convenient for the operator to use.
[0027] Compared with related technologies, the flue gas desulfurization absorption tower provided by this utility model has the following beneficial effects: by setting up baffles 12, vents 13 and other components in conjunction with atomizing nozzles 11, the baffles 12 can block and gather the flue gas entering the reaction tower 1, so that it can only be discharged through the vents 13 and thus can only be covered by the liquid sprayed by the atomizing nozzles 11, so that the liquid and flue gas can fully contact each other, avoiding dead zones, thereby improving the desulfurization effect of the flue gas, enhancing the desulfurization efficiency, and making it convenient for staff to use.
[0028] Example 2:
[0029] Please refer to Figures 1-6. An air inlet pipe 2 is fixedly connected to the lower left side of the reaction tower 1. Support legs 3 are fixedly connected to the bottom of the reaction tower 1 around its perimeter. A drain pipe 4 is fixedly connected to the bottom of the reaction tower 1. A drain valve 5 is installed on the surface of the drain pipe 4. An air outlet pipe 6 is fixedly connected to the top of the reaction tower 1.

A filter screen 14 is fixedly connected inside the vent hole 13. A flow guide shroud 15 is fixedly connected to the middle inside of the reaction tower 1. The inner wall of the flow guide shroud 15 is shaped like a frustum, narrow at the top and wide at the bottom. The top of the flow guide shroud 15 is in close contact with the bottom of the baffle plate 12.
[0030] Working principle: When the staff introduces the flue gas to be processed into the reaction tower 1 through the air inlet pipe 2, the flue gas entering the reaction tower 1 will be gathered by the guide hood 15. The guide hood 15 will quickly guide the flue gas upward to the baffle plate 12. The baffle plate 12 can block and gather the flue gas entering the reaction tower 1, so that it can only be discharged through the vent 13. The vent 13 is equipped with a filter screen 14, which can filter the particulate matter in the flue gas, thereby improving work efficiency and making it convenient for staff to use.
