Description

Technical Field

[0001] This utility model relates to the field of exhaust gas dehumidification, and more specifically, to an exhaust gas dehumidification device for thermal power plants. Background Technology

[0002] A thermal power plant, or coal-fired power plant for short, is a factory that uses combustible materials as fuel to produce electricity. Its basic production process is as follows: fuel burns to heat water and generate steam, converting the chemical energy of the fuel into heat energy. The steam pressure drives a turbine to rotate, converting the heat energy into mechanical energy. The turbine then drives a generator to rotate, converting the mechanical energy into electrical energy. The prime mover is usually a steam engine or a gas turbine. During the exhaust gas treatment process, the exhaust gas carries a significant amount of moisture, which dilutes the waste gas treatment reaction solution, affecting the efficiency and quality of waste gas treatment.

[0003] Application CN 114345088 A discloses a waste gas dehumidification device for thermal power plants, comprising a filtration module including a dust filter assembly and a backflushing assembly, the backflushing assembly being disposed within the dust filter assembly; a heat absorption module movably connected to the filtration module, the heat absorption module including a water storage assembly, a heat absorption assembly, and a starting assembly, the heat absorption assembly and the starting assembly being movably connected to the water storage assembly; and a dehumidification module. This invention achieves dual dehumidification of the waste gas through a pre-dehumidification assembly and a moisture absorption assembly, preventing excessive moisture from entering the next process and affecting the waste gas treatment quality. The use of a transmission assembly effectively transmits the waste gas, ensuring stable transmission and preventing backflow.

[0004] In the above-disclosed structure, the exhaust gas is treated by connecting the backflushing component and the heat absorption module through the filter module, and then dehumidified by the moisture absorption component. However, the lack of a combined folded cylinder and adsorption pleated layer makes it difficult to efficiently dehumidify the filtered exhaust gas, and it is impossible to cool and exchange heat at the dehumidification location to improve the water vapor condensation efficiency. The dehumidification effect is poor and the adaptability is insufficient, which needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a tail gas dehumidification device for thermal power plants. Through the support ring and folded cylinder inside the treatment cylinder and the adsorption pleated layer, combined with the externally connected spiral cooling pipe, heat exchange can be directly performed inside to condense water vapor, and then direct multi-layer adsorption dehumidification is carried out. It is highly efficient and stable. Furthermore, by installing a telescopic rod and an extrusion plate at the top, it can be squeezed downwards to precipitate, which is convenient for long-term operation, highly adaptable, and easy to control and use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0009] Furthermore, a cover plate is fixedly installed on the upper surface of the processing cylinder, and a telescopic rod is fixedly installed on the upper surface of the cover plate.

[0010] Furthermore, the head of the telescopic rod is fixedly connected to a squeezing plate, which is slidably connected to the upper end of the folding cylinder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 , Figure 4 and Figure 5A dehumidification device for exhaust gas in thermal power plants includes a treatment cylinder 1. An inlet pipe 11 is fixedly connected to the lower surface of the treatment cylinder 1. Supports 12 are fixedly connected to both sides of the interior of the treatment cylinder 1. A support ring 13 is fixedly connected to one end of each support 12. Guide rods 14 are fixedly connected to both sides of the upper surface of the support ring 13. A folded cylinder 15 is slidably sleeved on the surface of the guide rods 14. An adsorption pleated layer 16 is fixedly connected to the inner surface of the folded cylinder 15. The folded cylinder 15 is formed by a multi-layered structure with fluffy fibers, and gaps exist between the multi-layered structures to increase the adsorption area, improve the moisture absorption effect, and facilitate positioning. A reserved gap 17 is provided at one end of the adsorption pleated layer 16. The adsorption pleated layer 16 is located directly above the inlet pipe 11. The support ring... A spiral cooling pipe 18 is fixedly connected to the upper surface of the 13. The spiral cooling pipe 18 is fixedly sleeved on the outside of the folded cylinder 15. Both ends of the spiral cooling pipe 18 are fixedly connected to circulation pipes 19. The circulation pipes 19 are fixedly connected to one side surface of the processing cylinder 1. The filtered exhaust gas is introduced into the folded cylinder 15 from the inlet pipe 11. During the upward flow, it comes into contact with the adsorption pleated layer 16. The circulating cooling medium is introduced through the circulation pipe 19, which can reduce the internal temperature of the processing cylinder 1, thereby accelerating the condensation of water vapor. This is especially noticeable when passing through the folded cylinder 15. This ensures that the multi-layer adsorption pleated layer 16 adsorbs water vapor, while the remaining exhaust gas can flow upward and be discharged. This is convenient, efficient, easy to install and use, and highly adaptable.

[0028] Please see Figure 1 and Figure 2 A drain pipe 2 is fixedly connected to the lower side of the outer surface of the treatment cylinder 1, and an exhaust pipe 21 is fixedly connected to the upper side of the outer surface of the treatment cylinder 1. By installing the drain pipe and the exhaust pipe on the treatment cylinder, water can be drained from the bottom and exhaust can be vented from the top, avoiding mutual interference and facilitating combined use. The dehumidified exhaust gas can be discharged from the exhaust pipe 21 at the top, while the squeezed-out water can be discharged from the drain pipe 2 at the bottom, avoiding interference and facilitating adjustment and use.

[0029] Please see Figure 2 and Figure 3 A cover plate 27 is fixedly installed on the upper surface of the treatment cylinder 1. A telescopic rod 22 is fixedly installed on the upper surface of the cover plate 27. A squeezing plate 23 is fixedly connected to the head of the telescopic rod 22. The squeezing plate 23 is slidably connected to the upper end of the folding cylinder 15. The telescopic rod and the squeezing plate are installed by the cover plate, which can be combined and positioned. The telescopic control can be used to squeeze and drain water, which is efficient, stable and highly adaptable.

[0030] The extrusion plate 23 is slidably connected to the upper surface of the guide rod 14 and located inside the processing cylinder 1. A conical guide block 24 is fixedly connected to the lower surface of the extrusion plate 23. The conical guide block 24 is located in the middle of the folding cylinder 15. Pull ropes 25 are fixedly connected to both sides of the lower surface of the extrusion plate 23. A connecting ring 26 is fixedly connected to the lower end of the pull rope 25. The connecting ring 26 is fixedly connected to the upper surface of the folding cylinder 15. The extrusion plate is connected to the conical guide block, which facilitates the dispersion and discharge of backflowing gas. The pull rope and the positioning connecting ring can be used to pull the folding cylinder to unfold and reset, making it convenient to control and use. It is stable and efficient. When a certain amount of water vapor is adsorbed... After a certain time, the telescopic rod 22 extends, pushing the extrusion plate 23 downwards. This allows the connecting ring 26 to press down on the folding cylinder 15, compressing the unfolded adsorption pleated layer 16 downwards. By reducing the internal gaps, the adsorbed moisture can be squeezed out and discharged to the bottom of the treatment cylinder 1, facilitating drainage from the drain pipe 2. Then, the telescopic rod 22 retracts, allowing the pull rope 25 to move upwards via the extension rod 23. This causes the folding cylinder 15 to slide along the guide rod 14, thus allowing the adsorption pleated layer 16 to move upwards and unfold, restoring the multi-layered gap structure. This facilitates repeated adsorption and dehumidification, ensuring high efficiency, stability, and ease of adjustment.

[0031] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
