Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment, specifically a flue gas treatment device with dust removal function. Background Technology

[0002] In industrial production processes, many devices generate large amounts of dust-laden flue gas. If directly emitted, this will cause serious environmental pollution. Therefore, effective treatment of the flue gas is necessary. Flue gas treatment devices are equipment used to purify the flue gas generated during industrial production. Their main function is to remove or convert harmful substances (such as particulate matter, sulfur dioxide, nitrogen oxides, heavy metals, etc.) in the flue gas into harmless substances, so that they meet national or local environmental emission standards.

[0003] Traditional flue gas treatment devices are mostly fixed installations. Once installed, it is difficult to adjust their location according to actual needs. This fixed nature makes them particularly inconvenient in situations requiring flexible deployment, such as outdoor construction sites or temporary industrial work sites. For example, at construction sites or field work sites, the flue gas emission points may change frequently with the progress of construction. Fixed devices cannot adjust to these changes in a timely manner, resulting in low flue gas treatment efficiency or even ineffective treatment of flue gas. In addition, the operation process of traditional flue gas treatment devices is usually quite complex, requiring professional technicians for operation and maintenance. This not only increases labor costs but may also lead to difficulties in quickly starting the equipment in emergency situations. At the same time, these devices are often bulky and difficult to install and use in outdoor sites with limited space. Therefore, a flue gas treatment device with dust removal function is proposed to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] In the embodiments, by Figure 1-4 The present invention discloses a flue gas treatment device with dust removal function. The present invention includes a base 1, casters 2 are provided at the bottom of the base 1, a water tank 3 is fixedly connected to the top of the base 1, an air inlet pipe 4 is fixedly connected to the inner right wall of the water tank 3, an air inlet frame 5 is fixedly connected to the outer side of the air inlet pipe 4, a first fan 6 is provided inside the air inlet frame 5, a guide pipe 7 is fixedly connected to the inner left wall of the water tank 3, an absorption frame 8 is fixedly connected to the outer side of the guide pipe 7, a filter frame 9 is fixedly connected to the outer side of the absorption frame 8 through a pipe, a filter layer 10 is provided inside the filter frame 9, a baffle 11 is fixedly connected to the filter frame 9 through fasteners on the outer side of the filter layer 10, and an air outlet pipe 12 is fixedly connected to the outer side of the filter frame 9, a second fan 13 is provided inside the air outlet pipe 12.

[0028] Among them, the outer side of the base 1 is fixedly connected to the push frame 14, the air intake frame 5 is set with the outer width and the inner width, and the water tank 3 and the absorption frame 8 are both provided with observation windows.

[0029] In this embodiment, during actual use, the operator can easily push the entire device through the pusher 14 to quickly move it to the location where the flue gas needs to be treated. When the flue gas enters the air inlet frame 5, the design of being wider on the outside and narrower on the inside allows the airflow to gradually concentrate and distribute evenly before entering the water tank 3, enabling the airflow to fully contact the liquid in the water tank and improve the washing effect. The liquid inside the water tank 3 and the absorption frame 8 will gradually become turbid. The observation window can effectively observe the water level and quality, making it convenient to replace the liquid at regular intervals.

[0030] Both the water tank 3 and the absorption frame 8 have water inlets, and both have water outlets.

[0031] In this embodiment, during actual use, clean water or chemical absorbent is added to the water tank 3 and the absorption frame 8 through the water inlet. After the absorbent has been used for a period of time, it is discharged through the water outlet and replaced with a new absorbent to ensure that the absorption effect is always at its best.

[0032] Both the water tank 3 and the absorption frame 8 are fixedly connected to the inside of the porous distributor 15 located on the outside of the air inlet pipe 4 and the air guide pipe 7 respectively by fasteners, and both the water tank 3 and the absorption frame 8 are filled with filler.

[0033] In this embodiment, during actual use, the porous distributor 15 on the outside of the air inlet pipe 4 and the air guide pipe 7 disperses the flue gas into fine bubbles. When these bubbles rise in the liquid, they come into full contact with the liquid, increasing the gas-liquid contact area and thus improving the efficiency of water washing and chemical absorption. The filler material, such as ceramic rings or plastic balls, inside the water tank 3 and the absorption frame 8 further increases the gas-liquid contact area. When the bubbles pass through the filler layer, the harmful substances in the flue gas have more opportunities to react with the liquid, thereby improving the absorption effect.

[0034] The filter frame 9 has a groove inside, and the filter layer mesh 10 has a slide plate 16 that is slidably connected to the outside of the groove. A sealing gasket is provided on the outside of the slide plate 16.

[0035] In this embodiment, during actual use, the filter layer 10 is slidably connected to the slide groove in the filter frame 9 via the slide plate 16. This design makes the installation and replacement of the filter layer very convenient. When the filter layer needs to be replaced, simply pull out the slide plate, which greatly improves the convenience of maintenance. The sealing gasket on the outside of the slide plate 16 ensures the sealing between the filter layer and the filter frame, preventing unfiltered gas from passing through directly, thereby ensuring the filtration effect.

[0036] Each baffle 11 has a threaded connection to a bolt knob 17 that is threaded to the filter frame 9. Each baffle 11 has a sealing gasket on its inner side and a handle fixedly connected to its outer side.

[0037] In this embodiment, during actual use, the baffle 11 is threadedly connected to the filter frame 9 via bolts and knobs 17. This design ensures the stability of the baffle and prevents it from loosening due to airflow impact during processing, thereby ensuring the stability and sealing of the filter layer. The sealing gasket on the inner side of the baffle 11 further ensures the sealing, preventing unfiltered gas from passing directly, thus ensuring the filtration effect. The handle on the outer side of the baffle 11 facilitates the disassembly and installation of the baffle by the operator, improving the convenience of maintenance. When replacing the filter layer 10, the operator can easily disassemble the baffle 11 through the handle, and after replacement, reinstall the baffle 11 through the handle and fix it with bolts and knobs 17. Furthermore, the baffle 11 and the filter layer 10 can also be fixed and disassembled with bolts, so that the baffle 11 can be reused, and only the filter layer 10 needs to be replaced.

[0038] Working principle:

[0039] When absorbing flue gas, the inside of water tank 3 can be filled with clean water to filter large dust particles. The inside of absorption frame 8 can be filled with substances such as alkaline solution to absorb acidic gases and oxidant to absorb reducing gases. It is mainly used to remove acidic gases in flue gas, such as sulfur dioxide (SO2), hydrogen chloride (HCl), sulfur trioxide (SO3), etc. The filter mesh 10 can be made of activated carbon. Activated carbon adsorbs and removes volatile organic compounds (VOCs) and other harmful gases (such as nitrogen oxides, heavy metals, etc.) in flue gas. Before flue gas treatment, the device is first moved to a suitable flue gas absorption position by casters 2. Casters 2 are self-locking casters for easy movement or stopping.

[0040] During the intake stage: flue gas enters the intake frame 5 through the intake pipe 4, and the first fan 6 provides power to introduce the flue gas into the water tank 3.

[0041] Water washing stage: Flue gas enters the water through the porous distributor 15 in the water tank 3, forming fine bubbles, which initially remove particulate matter and soluble gases.

[0042] Chemical absorption stage: The flue gas washed with water enters the absorption frame 8 through the gas guide pipe 7, and enters the chemical absorbent through the porous distributor 15 in the absorption frame 8 to further remove acidic gases.

[0043] Filtration stage: The flue gas that has undergone chemical absorption enters the filter frame 9 through the pipe and undergoes deep filtration and adsorption through the filter layer mesh 10 to remove volatile organic compounds and other harmful gases.

[0044] Gas discharge stage: The treated flue gas is discharged from the device through the exhaust pipe 12, powered by the second fan 13.

[0045] Through the above design and improvements, this flue gas treatment device can efficiently remove harmful substances from flue gas, while also possessing good mobility and ease of maintenance, making it suitable for use at outdoor construction sites and temporary industrial operation sites.
