Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas desulfurization technology, specifically to an industrial waste gas desulfurization device. Background Technology

[0002] Flue gas desulfurization utilizes various alkaline absorbents or adsorbents to capture sulfur dioxide in flue gas and convert it into more stable and easily mechanically separable sulfur compounds or elemental sulfur, thereby achieving the purpose of desulfurization. The pollutants contained in flue gas mainly come from various material utilization and transformation processes such as combustion, including particulate matter, sulfur dioxide, nitrogen oxides and other pollutants. Among them, sulfur dioxide is one of the most important pollutants. Flue gas desulfurization is the most practical and feasible way to control sulfur dioxide pollution, and it can be divided into three categories: wet method, semi-dry method and dry method.

[0003] For example, patent document CN 222677692 U discloses an industrial waste gas desulfurization device, which relates to the field of waste gas treatment technology. This utility model includes a spray box, a cyclone separator component, and a reagent tank. A sealing cover is snapped and fixed to the top of the spray box, and an exhaust pipe is welded through the top of the sealing cover. A cyclone separator component is snapped and fixed inside the spray box, and a high-pressure air pump is set at one end of the cyclone separator component. A mixing box and a reagent tank are snapped and fixed from top to bottom at the bottom of the spray box. A liquid pump is snapped and fixed through one end of the outer circumference of the reagent tank. Multiple spray pipes are welded through the top edge of the mixing box. This utility model solves the problem that it is difficult for waste gas to come into efficient contact with the reagent by setting up a spray box, a cyclone separator component, and a reagent tank. It requires the waste gas to circulate to ensure the desulfurization efficiency of the waste gas. When the reagent is sprayed through the spray structure, some of the vaporized reagent will leave the device with the airflow, resulting in the waste of some reagent.

[0004] However, in actual use, due to its structural limitations, this structure can only perform linear flow desulfurization of industrial waste gas. The contact time between the waste gas and the vaporization desulfurization is short, making it impossible to obtain sufficient mixing conditions. At the same time, the equipment cannot perform rapid cooling, liquefaction, and recovery of desulfurization reagents, which cannot meet the needs of daily use. Therefore, it is urgent to design an industrial waste gas desulfurization device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an industrial waste gas desulfurization device to solve the problems mentioned in the background art. In actual use, due to the limitations of its own structure, the existing structure can only perform linear flow desulfurization operation of industrial waste gas. The contact time between waste gas and vaporization desulfurization is short, and sufficient mixing conditions cannot be obtained. At the same time, the equipment cannot perform rapid cooling, liquefaction and recovery of desulfurization reagents, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial waste gas desulfurization device, including a desulfurization outer tank, an inner liner seat inside the desulfurization outer tank, a flow annular groove between the desulfurization outer tank and the inner liner seat, cooling components at the upper and lower ends of the desulfurization outer tank, and material conveying components at the upper and lower ends of the cooling components.

[0007] The cooling assembly includes an exhaust top seat and an exhaust base, and the exhaust top seat and exhaust base are fixedly connected to the upper and lower ends of the desulfurization outer tank;

[0008] The material conveying assembly includes a gas collection hood and a gas conveying base. The top of the exhaust top seat is movably connected to the gas collection hood, and the bottom of the exhaust base is fixedly connected to the gas conveying base.

[0009] Preferably, an air inlet valve is provided on one side of the gas delivery seat, and an infusion valve is provided on the other side of the gas delivery seat.

[0010] Preferably, the top of the gas collecting hood is provided with a gas outlet valve, and the inside of the gas collecting hood is provided with a filter screen.

[0011] Preferably, a sealing ring is provided between the exhaust top seat and the gas collection hood.

[0012] Preferably, a gas supply side pipe is provided on all four sides between the exhaust top seat and the exhaust base, and a cooling circulation pipe is evenly provided on the side of the gas supply side pipe.

[0013] Preferably, a liquid control ring is provided at the edge between the exhaust top seat and the exhaust base, and an exhaust ring network groove is provided on the surface of the exhaust top seat and the inner wall of the exhaust base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This industrial waste gas desulfurization device, through its external desulfurization tank, inner liner, flow ring groove, exhaust top seat, exhaust base, gas collection hood, gas delivery seat, inlet valve, agent delivery valve, outlet valve, filter screen, and sealing ring, enables the equipment to perform more continuous and stable industrial waste gas desulfurization operations. In actual use, operators can introduce industrial waste gas and vaporized desulfurization reagent through the inlet valve and agent delivery valve on both sides of the gas delivery seat, respectively. The mixed gas flow first enters upwards into the inner liner inside the external desulfurization tank, and then enters the space between the external and inner liner from a fixed side point on the inner liner. The gas flows down into the exhaust base at the bottom of the desulfurization outer tank through the flow ring groove. After entering the exhaust base, it is then diverted along the four-sided gas supply pipes and transported upwards to the exhaust top seat. The exhaust ring groove of the exhaust top seat allows the gas to flow into the gas collection hood. The gas outlet valve of the gas collection hood can also be filtered by a filter screen, thereby achieving a longer and more uniform and thorough mixing of industrial waste gas and vaporized desulfurization reagent. At the same time, the entire gas collection hood can be quickly replaced at the exhaust top seat through the sealing ring, thereby realizing rapid maintenance of the equipment and demonstrating the practicality of the equipment design.

[0016] This industrial waste gas desulfurization device, through its desulfurization outer tank, exhaust top seat, exhaust base, gas delivery side pipe, cooling circulation pipe, liquid control ring pipe, and exhaust ring network trough, further improves the overall performance of the equipment. During daily use, operators can introduce circulating cooling water between the exhaust top seat and the exhaust base through the liquid control ring pipe. At this time, the cooling water can evenly enter the four sides of the gas delivery side pipe from the liquid control ring pipe. The cooling circulation pipe on the side of the gas delivery side pipe can achieve the annular winding flow of cooling water, which will more evenly cool the industrial waste gas and vaporized desulfurization reagent that are diverted into the gas delivery side pipe. This allows the desulfurized reagent to be re-liquefied for more thorough recovery, demonstrating the comprehensiveness of the equipment design. Attached Figure Description

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.

[0023] Please see Figure 1-4 One embodiment provided by this utility model:

[0024] An industrial waste gas desulfurization device includes a desulfurization outer tank 1, an inner liner seat 2 inside the desulfurization outer tank 1, a flow ring groove 3 between the desulfurization outer tank 1 and the inner liner seat 2, cooling components at the upper and lower ends of the desulfurization outer tank 1, material conveying components at the upper and lower ends of the cooling components, gas conveying side pipes 13 arranged on the four sides between the exhaust top seat 4 and the exhaust base 5, cooling circulation pipes 14 evenly arranged on the side of the gas conveying side pipes 13, liquid control ring pipes 15 arranged on the edge between the exhaust top seat 4 and the exhaust base 5, and exhaust ring mesh grooves 16 arranged on the surface of the exhaust top seat 4 and the inner wall of the exhaust base 5. Cooling water can enter evenly from the liquid control ring pipes 15 into the four-sided gas conveying side pipes 13. The cooling circulation pipes 14 on the side of the gas conveying side pipes 13 can realize the annular winding flow of cooling water, so as to perform a more uniform cooling operation on the industrial waste gas and vaporized desulfurization reagent that are diverted into the gas conveying side pipes 13.

[0025] The cooling assembly includes an exhaust top seat 4 and an exhaust base 5. The exhaust top seat 4 and the exhaust base 5 are fixedly connected to the upper and lower ends of the desulfurization outer tank 1. The conveying assembly includes a gas collecting hood 6 and a gas conveying seat 7. The top of the exhaust top seat 4 is movably connected to the gas collecting hood 6, and the bottom of the exhaust base 5 is fixedly connected to the gas conveying seat 7. An inlet valve 8 is provided on one side of the gas conveying seat 7, and a delivery valve 9 is provided on the other side. An outlet valve 10 is provided at the top of the gas collecting hood 6. A filter screen 11 is provided inside the gas collecting hood 6. A sealing ring 12 is provided between the exhaust top seat 4 and the gas collecting hood 6. Gas can flow into the gas collecting hood 6 through the exhaust ring groove 16 of the exhaust top seat 4, and the gas can also be filtered through the filter screen 11 at the outlet valve 10 of the gas collecting hood 6, thereby achieving a longer and more uniform and thorough mixing of industrial waste gas and vaporized desulfurization reagent.

[0026] Working principle: During use, the operator first introduces the industrial waste gas and the vaporized desulfurization reagent into the inlet valve 8 and the agent delivery valve 9 on both sides of the gas delivery seat 7, respectively. The mixed gas flow first enters upward into the inner liner seat 2 inside the outer desulfurization tank 1, then enters the flow ring groove 3 between the outer desulfurization tank 1 and the inner liner seat 2 from a fixed side, and then enters downward into the exhaust base 5 at the bottom of the outer desulfurization tank 1. After entering the exhaust base 5, the gas is then diverted along the four-sided gas delivery side pipes 13 and transported upward to the exhaust top seat 4. The exhaust ring mesh groove 16 of the exhaust top seat 4 allows the gas to flow into the gas collection hood 6, and the outlet valve 10 of the gas collection hood 6 can also filter the gas through the filter screen 11, thereby achieving a longer-term uniform flow of industrial waste gas and vaporized desulfurization reagent. The gas collection hood 6 can be quickly replaced at the exhaust top seat 4 via the sealing ring 12, enabling rapid maintenance of the equipment. During daily use, the operator can introduce circulating cooling water between the exhaust top seat 4 and the exhaust base 5 through the liquid control ring pipe 15. The cooling water can then evenly enter the four-sided gas delivery pipe 13 from the liquid control ring pipe 15. The cooling circulation pipe 14 on the side of the gas delivery pipe 13 can achieve annular winding flow of cooling water, which will cool the industrial waste gas and vaporized desulfurization reagent that are diverted into the gas delivery pipe 13 more evenly, so that the desulfurized reagent can be re-liquefied for more thorough recovery. The above is the complete working principle of this utility model.
