Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a multi-layer desulfurizer for waste gas. Background Technique

[0002] Waste gas refers to the toxic and harmful gases discharged by humans in the production and living processes. Especially in chemical plants, steel plants, pharmaceutical factories, coking plants, oil refineries, etc., the discharged waste gas has a strong smell, seriously polluting the environment and affecting human health.

[0003] Sulfur in waste gas is harmful to the air environment and human body. If desulfurization is not carried out before exhausting, it will lead to the formation of substances such as acid rain that harm the environment and human body. The existing desulfurization methods generally involve uniformly flowing the gas into the desulfurization device at the same time, and then making it reach the emission standard through multiple desulfurizations inside the desulfurization device before discharging. It is impossible to carry out the desulfurization operation by reducing the gas flow volume, which affects the efficiency of the device during desulfurization and increases too many desulfurization steps.

[0004] Therefore, we provide a multi-layer desulfurizer for waste gas. Content of the Utility Model

There are at least two centrifugal rotating cylinders, and the two centrifugal rotating cylinders are fixedly connected. An air inlet auxiliary pipe is fixedly connected to the side of the centrifugal rotating cylinder away from the air inlet pipe. A middle support ring is arranged between the air inlet auxiliary pipe and the air inlet pipe, and the middle support ring is fixedly connected to the centrifugal rotating cylinder. Sealing auxiliary rings are arranged on both sides corresponding to the middle support ring. A plurality of guiding cones are arranged between the sealing auxiliary ring and the middle support ring. A flow channel is arranged between the two guiding cones.

[0009] Preferably, a guiding support plate is arranged inside the first confluence cylinder. The guiding support plate is located between the circulation cylinder and the circulation auxiliary cylinder, and is fixedly connected to both the circulation cylinder and the circulation auxiliary cylinder at the same time.

[0013] Compared with the prior art, the utility model provides a multi-layer desulfurizer for waste gas, and has the following beneficial effects:

And by setting the circulation cylinder and the circulation groove in the same flow direction, the stability of the gas flow direction during air flow is ensured.

[0016] In the utility model, the dispersed gas is desulfurized simultaneously. By reducing the volume of the gas flow, the high efficiency of the adsorption plate desulfurization is improved, and the effect of efficiently removing sulfur from the waste gas by the device can be improved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Embodiment 1: A multi-layer desulfurizer for waste gas, as Figures 1-4As shown in the figure, it includes a centrifugal rotating cylinder 2 and an air inlet pipe 1 fixedly arranged on one side of the centrifugal rotating cylinder 2. There are at least two centrifugal rotating cylinders 2, and the two centrifugal rotating cylinders 2 are fixedly connected. A gas inlet auxiliary pipe 3 is fixedly connected to the side of the centrifugal rotating cylinder 2 away from the air inlet pipe 1. A middle support ring 13 is arranged between the gas inlet auxiliary pipe 3 and the air inlet pipe 1. The middle support ring 13 is fixedly connected to the centrifugal rotating cylinder 2. Sealing auxiliary rings 14 are arranged on both corresponding sides of the middle support ring 13. A number of guiding cones 4 are arranged between the sealing auxiliary ring 14 and the middle support ring 13. A flow-through groove 5 is arranged between two guiding cones 4. A flow-through cylinder 6 is arranged on one side of the flow-through groove 5. The flow-through cylinder 6 is fixedly connected to both guiding cones 4 at the same time. When the device operates, under the guidance of the air inlet pipes 1 and the gas inlet auxiliary pipes 3 on both sides, the gas flowing from both sides is respectively transferred into the two centrifugal rotating cylinders 2. Then, under the limitation of the middle support ring 13 and the sealing auxiliary rings 14 on both sides, and the diversion and support of a plurality of guiding cones 4, the gas inside the two centrifugal rotating cylinders 2 is dispersed and flows into a plurality of flow-through cylinders 6 through the diversion of the flow-through groove 5. And by placing the desulfurization adsorption plate inside the flow-through groove 5 under the support of the two guiding cones 4, and also placing an adsorption plate inside the flow-through cylinder 6, the first-step desulfurization operation can be carried out on the gas rotated out of the centrifugal rotating cylinder 2. And by setting the flow-through cylinder 6 and the flow-through groove 5 in the same flow direction, the stability of the gas flow direction is ensured when the air flows, so as to desulfurize the dispersed gas at the same time. By reducing the volume of the gas flow, the high efficiency of the adsorption plate desulfurization is improved, and the effect of the device for efficiently removing sulfur in the waste gas can be improved.

[0026] As Figures 1-4 shown, a flow-through auxiliary cylinder 7 is arranged on one side of the flow-through cylinder 6. The middle support ring 13 is located between the flow-through cylinder 6 and the flow-through auxiliary cylinder 7. The connection methods of the flow-through cylinder 6 and the flow-through auxiliary cylinder 7 are the same. The sides of the flow-through cylinder 6 and the flow-through auxiliary cylinder 7 away from the guiding cone 4 are fixedly connected to a first confluence cylinder 8 at the same time. The first confluence cylinder 8 is used for the combined flow of the gas inside the flow-through cylinder 6 and the flow-through auxiliary cylinder 7. Under the simultaneous flow guidance and desulfurization support of the flow-through auxiliary cylinder 7, the same desulfurization operation can be carried out on the gas on the other side. And through the connection of the first confluence cylinder 8, the gas flowing into the flow-through cylinder 6 and the flow-through auxiliary cylinder 7 is combined. And by arranging an adsorption plate inside the guiding support plate 9, the combined gas can be desulfurized again. By combining the flow-through cylinder 6 and the flow-through auxiliary cylinder 7 for combined flow, the volume of the residual sulfur in the mixed gas can be increased, so that the overall desulfurization operation can be carried out on it, and the reliability of the device during adsorption can be improved.

[0027] As Figures 1-4As shown in the figure, a guiding support plate 9 is arranged inside the first confluence cylinder 8. The guiding support plate 9 is located between the circulation cylinder 6 and the circulation auxiliary cylinder 7. The guiding support plate 9 is fixedly connected to both the circulation cylinder 6 and the circulation auxiliary cylinder 7. Through the inclined diversion of the guiding support plate 9, the flow direction of the gas inside the circulation cylinder 6 and the circulation auxiliary cylinder 7 can be adjusted, thereby adjusting the flow direction of sulfur in the gas and further improving the comprehensiveness of desulfurization.

[0028] Embodiment 2: A multi-layer desulfurizer for waste gas, as Figures 1-4 shown, on one side of the first confluence cylinder 8 away from the circulation cylinder 6, an inclined desulfurization pipe 10 is fixedly connected. The inclined desulfurization pipe 10 is used for further filtration of the gas. By setting the inclined desulfurization pipe 10 as an inclined structure, the gas flowing out of the first confluence cylinder 8 can flow obliquely, so as to improve the comprehensive multi-angle contact between the gas and the adsorption plate installed inside the inclined desulfurization pipe 10, and thus further improve the desulfurization effect.

[0029] As Figures 1-4 shown, an inclined auxiliary pipe 12 is arranged below the inclined desulfurization pipe 10. The inclined auxiliary pipe 12 is fixedly connected to the first confluence cylinder 8. The inclined desulfurization pipe 10 and the inclined auxiliary pipe 12 are internally connected. The inclined desulfurization pipe 10 and the inclined auxiliary pipe 12 are both fixedly connected to a second confluence cylinder 11. The second confluence cylinder 11 is used for the combined flow of the gas inside the inclined desulfurization pipe 10 and the inclined auxiliary pipe 12. By making the desulfurized gas in the inclined desulfurization pipe 10 and the inclined auxiliary pipe 12 flow towards the second confluence cylinder 11, and by setting the second confluence cylinder 11 in a relatively long horizontal state, the stability and slowness of the combined gas flow are ensured, and the stability of the last step of desulfurization of the device is improved.

[0030] Working principle: Under the guidance of the two side inlet pipes 1 and the inlet auxiliary pipe 3, the gas flowing from both sides is respectively diverted into the two centrifugal rotating cylinders 2. Then, under the limitation of the middle support ring 13 and the two side sealing auxiliary rings 14, and with the diversion support of a plurality of guiding cones 4, the gas inside the two centrifugal rotating cylinders 2 is dispersed and flows into a plurality of circulation cylinders 6 through the diversion of the circulation grooves 5. And by placing the desulfurization adsorption plate inside the circulation grooves 5 supported by the two guiding cones 4, and also placing adsorption plates inside the circulation cylinders 6, the first-step desulfurization operation can be carried out on the gas rotated out of the centrifugal rotating cylinders 2. And by setting the circulation cylinders 6 and the circulation grooves 5 in the same flow direction, the stability of the gas flow direction is ensured, so as to desulfurize the dispersed gas simultaneously. By reducing the volume of the gas flow, the high efficiency of the adsorption plate desulfurization is improved, and the effect of efficiently removing sulfur in the waste gas by the device can be improved.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
