Description

Technical Field

[0001] This utility model relates to industrial demisters, and more particularly to a recyclable dry demister device. Background Technology

[0002] As is well known, the demister is an important component of the desulfurization tower. The function of the demister is to capture the mist particles and slurry droplets entrained in the flue gas during the spray absorption process.

[0003] The efficiency of a demister depends not only on its structure but also on the density and size of the mist particles. The atomized particle size of the nozzle is related to the viscosity of the absorbent, the spray force, and the nozzle structure.

[0004] Existing demisters include baffle demisters, swirl impeller demisters, and multi-stage demisters. None of these existing demisters can collect the liquid formed during the demistering process, and therefore cannot achieve the recovery and recycling of liquid droplets from the gas. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a recyclable dry demister that can collect mist droplets separated from the airflow during the demister process, thereby realizing the recovery and recycling of useful substances in the gas.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a recyclable dry demisting device, including a hollow cylindrical fixed cylinder; the cylindrical fixed cylinder is provided with wave plates distributed in a circle; the spacing between any two adjacent wave plates is the same;

[0007] The lower end of the corrugated plate is provided with a liquid guiding groove; the bottom of the cylindrical fixed cylinder is provided with an annular liquid collecting pipe; the liquid collecting pipe is fixedly connected to the lower end of the cylindrical fixed cylinder; the liquid collecting pipe is provided with a slot that matches the corrugated plate.

[0008] The liquid collection pipe is provided with a vertical liquid guide pipe that is connected to the liquid collection pipe.

[0009] Furthermore, the bottom of the liquid guiding groove is an inclined surface.

[0010] Furthermore, the corrugated plate is made of polymer material or stainless steel.

[0011] Furthermore, the corrugated plate has a first inclined surface on one side of the end with the liquid guiding groove and a second inclined surface on the other side.

[0012] Furthermore, the liquid collection tube is welded to the lower end of the cylindrical fixed tube.

[0013] Furthermore, the cylindrical fixing cylinder is made of stainless steel; a limit flange is provided at the upper end of the cylindrical fixing cylinder.

[0014] Furthermore, the upper end of the cylindrical fixed cylinder is provided with a limiting ring that defines the position of the waveform plate; the limiting ring is provided with a slot that matches the waveform plate; the lower end of the limiting ring is inserted into the cylindrical fixed cylinder and is detachably connected to the cylindrical fixed cylinder.

[0015] The beneficial effects of this utility model are: the recyclable dry demisting device described in this utility model has a liquid guiding groove at the lower end of the corrugated plate and an annular liquid collection pipe at the lower end of the cylindrical fixed cylinder.

[0016] During the demisting process, droplets are formed on the corrugated plate. Under the influence of gravity, these droplets flow along the corrugated plate into the liquid guiding tank, where they are collected and guided into the liquid collection pipe. Finally, the liquid is discharged through the vertical liquid guiding pipe, facilitating the recycling of the collected liquid. In summary, the recyclable dry demisting device described in this application is beneficial for collecting mist droplets in flue gas, is environmentally friendly, ensures the normal operation of the equipment, and extends its service life. Furthermore, it enables the collection of useful substances from the mist, achieving recycling and turning waste into treasure.

[0017] Finally, the liquid formed on the demister is discharged through the liquid guide groove, reducing the secondary contact time between the liquid and the flue gas and preventing the liquid from re-entering the flue gas and forming mist. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 9 As shown, the recyclable dry demisting device of this utility model includes a hollow cylindrical fixed cylinder 100; the cylindrical fixed cylinder 100 is provided with corrugated plates 300 arranged in a circular pattern; the spacing between any two adjacent corrugated plates 300 is the same.

[0031] The cylindrical fixing cylinder 100 is used to install and fix the corrugated plate 300; at the same time, by setting the spacing between any two adjacent corrugated plates 300 to be the same, the uniformity of airflow through the demister can be ensured, thus ensuring the demisting effect.

[0032] The cylindrical fixing tube 100 can be made of stainless steel or polymer materials such as polypropylene (PP) or FRP. Stainless steel has high strength and is easy to manufacture.

[0033] A liquid guiding groove 310 is provided at the lower end of the corrugated plate 300; the liquid guiding groove 310 and the corrugated plate 300 can be integrally formed. The corrugated plate 300 can be made of polymer material or stainless steel. When the corrugated plate 300 is made of polymer material, the liquid guiding groove 310 and the corrugated plate 300 are integrally formed. When the corrugated plate 300 is made of stainless steel, the liquid guiding groove 310 can be welded to the lower end of the corrugated plate 300, or the liquid guiding groove 310 can be formed by bending at the lower end of the corrugated plate 300. The main function of the liquid guiding groove 310 is to collect liquid and facilitate the guidance of liquid to one side of the demister.

[0034] The cylindrical fixed cylinder 100 has an annular liquid collection pipe 200 at its bottom; the liquid collection pipe 200 is fixedly connected to the lower end of the cylindrical fixed cylinder 100; the liquid collection pipe 200 has a slot 210 that matches the corrugated plate 300; the main function of the liquid collection pipe 200 is to collect the liquid. The liquid collection pipe 200 can be made of stainless steel.

[0035] The liquid collection pipe 200 is provided with a vertical liquid guide pipe 400 that communicates with the liquid collection pipe 200. The main function of the vertical liquid guide pipe 400 is to guide the collected liquid and discharge it.

[0036] In the operation of the recyclable dry demister described in this utility model, the recyclable dry demister is installed on the top of the desulfurization tower, and the vertical liquid guide pipe 400 is connected to the outflow pipe on the desulfurization tower.

[0037] When the flue gas passes through the demister, the flue gas containing mist droplets flows over the corrugated plate 300 at a certain speed. Since the corrugated plate 300 is wavy, the gas impacts the corrugated plate under the action of gas inertia, which causes the mist droplets to accumulate. When the accumulated droplets become so large that their own gravity exceeds the resultant force of the gas's upward force and the liquid's surface tension, the droplets are separated from the surface of the corrugated plate.

[0038] The separated droplets are guided into the liquid collection pipe 200 through the liquid guide groove 310 at the lower end of the corrugated plate 300, and finally discharged through the vertical liquid guide pipe, which is conducive to realizing the recycling of the collected liquid.

[0039] In summary, the recyclable dry demister described in this application is beneficial for collecting mist droplets in flue gas, is environmentally friendly, ensures normal operation of the equipment, and extends its service life. Secondly, it can collect useful substances in the mist, enabling recycling and turning waste into treasure. Finally, the liquid formed on the demister is discharged through the liquid guide tank, reducing the secondary contact time between the liquid and the flue gas and preventing the liquid from re-entering the flue gas and forming mist.

[0040] In one feasible embodiment, to facilitate the flow of the collected liquid, the bottom of the liquid guide trough 310 is further inclined surface 340.

[0041] In one feasible embodiment, the corrugated plate 300 is made of a polymer material or stainless steel. Specifically, the polymer material is polypropylene (PP) or FRP; the stainless steel is 316L or 317L.

[0042] In a feasible embodiment, in order to avoid the flow of airflow by the liquid guide groove 310 at the bottom of the corrugated plate 300, a first inclined surface 320 is provided on one side of the end of the corrugated plate 300 where the liquid guide groove 310 is provided, and a second inclined surface 330 is provided on the other side.

[0043] In one feasible embodiment, for ease of manufacturing, the liquid collection tube 200 is welded to the lower end of the cylindrical fixed tube 100.

[0044] In one feasible embodiment, to facilitate the installation of the demister in the desulfurization tower, the cylindrical fixing cylinder 100 is further made of stainless steel; a limit flange is provided at the upper end of the cylindrical fixing cylinder 100.

[0045] In one feasible embodiment, to facilitate fixing the waveform plate 300, a limiting ring 500 is further provided at the upper end of the cylindrical fixing cylinder 100 to limit the position of the waveform plate 300; the limiting ring 500 is provided with a slot that matches the waveform plate 300; the lower end of the limiting ring 500 is inserted into the cylindrical fixing cylinder 100 and is detachably connected to the cylindrical fixing cylinder 100.
