Description

Technical Field

[0001] The utility model relates to the technical field of purification towers, and specifically relates to a glass fiber reinforced plastic acid mist purification tower. Background Art

[0002] In some chemical production, electroplating, metallurgy and pharmaceutical industries, a large amount of acidic waste gas is generated during production, which will harm the environment and human health. The FRP acid mist purification tower absorbs and neutralizes the acidic waste gas through chemical principles, thereby reducing the pollution of acid mist waste gas to the environment.

[0003] The existing purification tower purification works as follows: an air inlet pipe is set at the bottom of the purification tower, and an air outlet pipe is set at the top of the purification tower. After the waste gas to be treated enters the purification tower from the air inlet pipe, it passes through the packing layer, spray area and adsorption area in turn, and is finally discharged from the air outlet pipe.

[0004] Although this can achieve the neutralization and purification of acid mist, the following problems still exist: when the acid mist passes through the packing layer, spray area and adsorption area in the purification tower, due to the lack of retention structure, the acid mist has a short retention time in the spray area, which may cause some of the acid mist to be not completely neutralized when discharged from the outlet pipe. Utility Model Content

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 2 to Figure 5 As shown, this embodiment proposes a glass fiber reinforced plastic acid mist purification tower, which includes a tower body 1, an air inlet pipe 11 is provided at the lower end of the tower body 1, and an air outlet pipe 12 is provided at the top of the tower body 1. In the tower body 1 in this embodiment, a first purification chamber 13 and a second purification chamber 14 are provided from bottom to top, respectively, and a retention mechanism for extending the retention time of the acid mist in the first purification chamber 13 by sealing and opening the first purification chamber 13 is provided between the first purification chamber 13 and the second purification chamber 14, a plurality of first spray heads 31 are fixed on the top of the first purification chamber 13, a plurality of second spray heads 32 are fixed on the top of the second purification chamber 14, a first packing layer 41 is provided between the first spray head 31 and the air inlet pipe 11, and a second packing layer 42 is provided on the upper end of the retention mechanism.

[0028] In this embodiment, a water storage tank 2 is still provided outside the tower body 1, and a water pipe 21 connected to the water outlet of the water storage tank 2 is fixed on the outer wall of the tower body 1, and each of the first spray head 31 and the second spray head 32 is connected to the water pipe 21. By controlling the water storage chamber, the water discharge of the first spray head 31 and the second spray head 32 can be synchronously controlled, and the control efficiency is higher.

[0029] In this embodiment, an adsorption layer 43 is provided between the second spray head 32 and the gas outlet pipe 12. The adsorption layer 43 is fixedly connected to the inner wall of the tower body 1 and is composed of activated carbon. The design of the adsorption layer 43 ensures that some gases that have not been neutralized are finally adsorbed by the activated carbon, thereby enhancing the purification effect.

[0030] The retention mechanism in this embodiment includes a retention plate 6, a first limiting plate 51 and a second limiting plate 52 parallel to the first limiting plate 51 are fixed on the inner wall of the tower body 1, and a first air guide hole 521 is provided at the center of the first limiting plate 51 and the second limiting plate 52. The retention plate 6 is arranged between the first limiting plate 51 and the second limiting plate 52, and is slidably connected to the inside of the tower body 1. A gas guide structure for introducing the gas in the first purification chamber 13 into the second purification chamber 14 is provided between the retention plate 6 and the inner wall of the tower body 1. The vertical projection of the first air guide hole 521 falls within the retention plate 6, which is used to prevent the retention plate 6 from detaching from the first limiting plate 51 or the second limiting plate 52. The retention plate 6 in this embodiment uses its own gravity to block the first air guide hole 521 on the first limiting plate 51, so that the gas to be purified will not enter the second purification chamber 14 immediately after entering the first purification chamber 13, and the gas stays in the first purification chamber 13 for a longer time, and the purification is more thorough. When the volume of the gas to be purified entering the first purification chamber 13 increases, the first retention plate 6 is pushed out, and the gas in the first purification chamber 13 flows from the first air guide hole 521 to the air guide structure and then enters the second purification chamber 14 for further purification.

[0031] In this embodiment, the first limit plate 51 is arranged at the lower end of the second limit plate 52, and the second limit plate 52 is provided with a plurality of limit members 522 near the first limit plate 51, which are used to prevent the retention plate 6 from contacting the second limit plate 52, so as to seal the first air guide hole 521 on the second limit plate 52, so that the gas in the first purification chamber 13 is blocked. A sliding groove 5221 is arranged in the limit member 522, and a plurality of sliding members 61 are arranged on the retention plate 6. The sliding members 61 correspond to the limit members 522 one by one, and the sliding members 61 are cylindrical structures, and the sliding members 61 are slidably connected with the sliding groove 5221. Such a design allows the retention plate 6 to slide between the first limit plate 51 and the second limit plate 52 without being deviated, and always slides along the direction of the sliding groove 5221.

[0032] The air guide structure in this embodiment includes an air guide member 7 fixedly arranged on the inner wall of the tower body 1, a sliding hole is provided in the center of the air guide member 7 to be slidably connected to the retention plate 6, and a plurality of second air guide holes 71 are provided on the outer wall of the sliding hole, and the projection surface of the second air guide hole 71 is a semicircular structure. The provision of multiple air guide holes disperses the gas entering the air guide member 7, so that the gas flows from the first purification chamber 13 to the second purification chamber 14 more quickly.

[0033] In this embodiment, a limit spring 523 is further provided at the bottom of the sliding groove 5221, one end of which is fixedly connected to the bottom of the sliding groove 5221, and the other end of which is fixedly connected to the limit member 522. The design of the limit spring 523 increases the pressure when the retention plate 6 abuts against the first limit plate 51, so that the time for the gas to be purified to stay in the first purification chamber 13 is extended, and the gas purification is more thorough.

[0034] The working process of this embodiment is as follows: when the acidic gas enters the tower body 1, the air pressures of the first purification chamber 13 and the second purification chamber 14 in the tower body 1 are the same, and the retention plate 6 abuts against the first air guide hole 521 on the first limit plate 51 under the elastic action of its own gravity and the limit spring 523 to seal. After the acidic gas to be purified enters the tower body 1 from the air inlet pipe 11, the first purification chamber 13 is in a sealed state, and the gas to be purified is fully neutralized and purified by the first spray head 31 in the first purification chamber 13. As the gas in the first purification chamber 13 increases, the air pressure rises, and the retention plate 6 is lifted up by the gas. At this time, the gas enters the second purification chamber 14 through the first air guide hole 521 and the second air guide hole 71, and is purified and adsorbed in turn, and finally discharged from the exhaust pipe.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
