Description

Technical Field

[0001] This utility model belongs to the technical field of activated carbon adsorption towers, and relates to an adsorption tower, and more particularly to an assembled corrosion-resistant adsorption tower. Background Technology

[0002] Factory workshops and other production operations generate irritating and harmful gases and pollutants, which can pollute the natural ecosystem, especially the air environment within the factory area, posing a significant threat to human health. Activated carbon adsorption towers are environmental protection devices used to treat organic waste gases and odors, primarily utilizing the adsorption properties of activated carbon to remove organic pollutants and odors from industrial waste gases.

[0003] Traditional activated carbon adsorption towers typically use stainless steel or carbon steel for the tower body, and stainless steel perforated plates or wire mesh for the activated carbon bed. When activated carbon adsorbs a large amount of pollutants, it develops a corrosive effect, causing corrosion to objects it comes into contact with, most notably the bed itself. Corrosion of the bed reduces the overall structural strength, potentially leading to material leakage and affecting deodorization efficiency. In severe cases, it can even cause equipment collapse, resulting in safety accidents. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an assembled corrosion-resistant adsorption tower. It solves the technical problem of existing adsorption towers being susceptible to corrosion, resulting in a short service life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An assembled corrosion-resistant adsorption tower includes a tower shell with adsorption chambers. The tower shell has a waste gas inlet and a waste gas outlet on opposite sides. The adsorption chamber is characterized by having several supporting frames arranged at intervals between the waste gas inlet and the waste gas outlet. Corrosion-resistant bed plates are fixed on the sides of adjacent frames. A bed for accommodating activated carbon is formed between two corrosion-resistant bed plates between adjacent frames. The corrosion-resistant bed plate includes fiberglass grating and PP wire mesh. The PP wire mesh covers one side surface of the fiberglass grating and is located on the surface of the fiberglass grating closest to the bed.

[0007] The adsorption tower of this application has several supporting frames arranged at intervals inside the adsorption chambers. The supporting frames are used to install and fix the corrosion-resistant bed plate to strengthen the structural strength of the activated carbon separating the corrosion-resistant bed plate, prevent the corrosion-resistant bed plate from collapsing, and thus increase the service life of the adsorption tower.

[0008] This adsorption tower uses a new type of corrosion-resistant bed plate to separate the activated carbon. The corrosion-resistant bed plate is composed of fiberglass grating and PP wire mesh. Fiberglass grating and PP wire mesh have high corrosion resistance and good material stability. They are difficult to corrode when in direct contact with activated carbon, thus greatly extending the service life of this adsorption tower.

[0009] In this application, the PP wire mesh in the corrosion-resistant bed plate is located on the side where the activated carbon is located and is in direct contact with the activated carbon. The fiberglass grating on the back of the PP wire mesh can play a supporting role for the PP wire mesh. The small pore size of the PP wire mesh can effectively block the activated carbon and prevent it from leaking into the interior of the tower shell and causing corrosion. This design further extends the service life of the adsorption tower.

[0010] In the above-mentioned assembled anti-corrosion adsorption tower, the sides of the supporting frame are all bolted with pressure strips, and the outer edges of the corrosion-resistant bed plate are located between the pressure strips and the supporting frame, and the corrosion-resistant bed plate is pressed and fixed by bolts.

[0011] In this application, the outer edge of the corrosion-resistant bed plate is pressed and fixed to the support frame by pressure strips. The pressure strips are distributed at the outer edge to avoid contact with activated carbon and thus prevent corrosion. This fixing method can further improve the service life of the adsorption tower.

[0012] In the aforementioned assembled anti-corrosion adsorption tower, the pressure strip is made of fiberglass.

[0013] The pressure strip of this application is made of corrosion-resistant fiberglass. This design ensures that even if it comes into contact with the surrounding activated carbon, it will not cause corrosion. This effectively guarantees the fixing strength of the corrosion-resistant bed plate, thereby further improving the service life of the adsorption tower.

[0014] In the aforementioned assembled anti-corrosion adsorption tower, the supporting frame is arranged with several assembled profiles at intervals in the vertical direction. The assembled profiles are horizontally arranged and their two ends abut against adjacent corrosion-resistant bed plates to form support.

[0015] Assembled profiles are fixed vertically to the support frame. The two ends of the assembled profiles abut against the corrosion-resistant bed plate, which can support the middle position of the corrosion-resistant bed plate. This compensates for the weakness of the middle position due to the outer edge being clamped by the pressure strip, effectively reducing the risk of collapse and further improving the service life of the adsorption tower.

[0016] In the aforementioned assembled anti-corrosion adsorption tower, at least two ends of the assembled profile are made of fiberglass.

[0017] At least two ends of the aforementioned assembled profiles are made of fiberglass. This design effectively prevents corrosion from contact with activated carbon, thus reducing the support strength.

[0018] In the aforementioned assembled anti-corrosion adsorption tower, the corrosion-resistant bed plates are all vertically arranged, and an activated carbon filling port is provided at the top of the tower shell corresponding to each bed, and an activated carbon discharge port is provided at the bottom of the tower shell corresponding to each bed.

[0019] All corrosion-resistant bed plates in this application are vertically arranged with activated carbon filling and unloading ports in the vertical direction. This design makes it very convenient to fill and replace activated carbon.

[0020] In the aforementioned assembled anti-corrosion adsorption tower, the supporting frame comprises several square tubular fiberglass profiles, which are used to construct a frame.

[0021] The support frame of this application is also made of fiberglass profile. If there is corrosive gas or liquid, or if the activated carbon that has absorbed the corrosive gas comes into contact with it, it will not cause corrosion. The overall adsorption tower has excellent corrosion resistance, thus resulting in a longer service life.

[0022] In the aforementioned assembled corrosion-resistant adsorption tower, the tower shell includes multiple exterior facades, each of which is formed by splicing together SMC plates.

[0023] The entire tower shell of this application is made of high-strength SMC plates, which have strong corrosion resistance and can prevent the tower shell from being corroded by the inside or outside of the tower, thus greatly extending the service life of the adsorption tower.

[0024] In the aforementioned assembled anti-corrosion adsorption tower, at least two layers of PP wire mesh are laid on one side surface of the fiberglass grating.

[0025] The multi-layered PP wire mesh design can better block activated carbon particles, and the mesh size of the PP wire mesh can be selected according to the particle size of the activated carbon, thus better blocking the activated carbon and greatly extending the service life of this adsorption tower.

[0026] In the aforementioned assembled corrosion-resistant adsorption tower, the bottom of the adsorption tower is equipped with support legs to facilitate unloading from the activated carbon discharge port.

[0027] The beneficial effects of this utility model are:

[0028] 1. This adsorption tower uses a new type of corrosion-resistant bed plate to separate the activated carbon. The corrosion-resistant bed plate is composed of fiberglass grating and PP wire mesh. Fiberglass grating and PP wire mesh have high corrosion resistance and good material stability. They are difficult to corrode when in direct contact with activated carbon, thus greatly extending the service life of this adsorption tower.

[0029] 2. In the corrosion-resistant bed plate of this application, the PP wire mesh is located on the side where the activated carbon is located and is in direct contact with the activated carbon. The fiberglass grating on the back of the PP wire mesh can play a supporting role for the PP wire mesh. The small pore size of the PP wire mesh can effectively block the activated carbon and prevent leakage. This design further extends the service life of the adsorption tower.

[0030] 3. The support frame of this application is also made of fiberglass profile. If there is corrosive gas or liquid, or if the activated carbon that has absorbed the corrosive gas comes into contact with it, it will not cause corrosion. The overall adsorption tower has excellent corrosion resistance, thus resulting in a longer service life. Attached Figure Description

[0035] like Figures 1-3 The illustrated prefabricated corrosion-resistant adsorption tower includes a tower shell 1 with an adsorption chamber 11. The tower shell 1 comprises four main exterior surfaces, each formed by splicing together SMC (Silicone Molding Compound) panels. Constructed from high-strength SMC panels, the tower shell 1 exhibits strong corrosion resistance, preventing corrosion from both internal and external sources and significantly extending its service life. Support legs 5 are installed at the bottom of the adsorption tower to elevate the entire tower. This elevation, a certain distance above the ground, prevents ground moisture from corroding the bottom of the tower shell 1, effectively extending its service life.

[0036] The tower shell 1 has waste gas inlets 12 and waste gas outlets 13 on opposite sides. Adsorption chambers 11 are located between the waste gas inlets 12 and outlets 13, with several supporting frames 2 arranged at intervals. Corrosion-resistant bed plates 3 are fixed to the sides of adjacent frames. Two corrosion-resistant bed plates 3 between adjacent frames enclose a bed 21 for accommodating activated carbon. The corrosion-resistant bed plate 3 includes fiberglass grating 31 and PP wire mesh 32. The PP wire mesh 32 covers one side of the fiberglass grating 31 and is located on the side of the fiberglass grating 31 closest to the bed 21. In this application, the adsorption chambers 11 inside the adsorption tower have several supporting frames 2 arranged at intervals. The supporting frames 2 are used to install and fix the corrosion-resistant bed plates 3 to strengthen the structural strength of the corrosion-resistant bed plates 3 in separating the activated carbon, preventing the corrosion-resistant bed plates 3 from collapsing, thereby increasing the service life of the adsorption tower. This adsorption tower uses a novel corrosion-resistant bed plate 3 to separate the activated carbon. The corrosion-resistant bed plate 3 is composed of fiberglass grating 31 and PP wire mesh 32. Both the fiberglass grating 31 and PP wire mesh 32 have high corrosion resistance and good material stability, making them difficult to corrode when in direct contact with activated carbon, thus greatly extending the service life of the adsorption tower. In this application, the PP wire mesh 32 in the corrosion-resistant bed plate 3 is located on the side containing the activated carbon, directly contacting it. The fiberglass grating 31, located on the back of the PP wire mesh 32, provides support for it. The small pore size of the PP wire mesh 32 effectively blocks the activated carbon, preventing leakage into the tower shell 1 and causing corrosion. This design further extends the service life of the adsorption tower. Preferably, a design with 2-3 layers of PP wire mesh better blocks activated carbon particles, and the mesh size of the PP wire mesh can be selected according to the particle size of the activated carbon, further enhancing the blocking effect and significantly extending the service life of the adsorption tower.

[0037] Furthermore, the sides of the support frame 2 are bolted with pressure strips 4, and the outer edges of the corrosion-resistant bed plate 3 are located between the pressure strips 4 and the support frame 2, and are pressed and fixed by bolts. In this application, the outer edges of the corrosion-resistant bed plate 3 are pressed and fixed to the support frame 2 by the pressure strips 4. The distribution of the pressure strips 4 at the outer edges avoids contact with the activated carbon, thus preventing corrosion. This fixing method further improves the service life of the adsorption tower. Preferably, the pressure strips 4 are made of fiberglass. The pressure strips 4 in this application are made of corrosion-resistant fiberglass, so this design will not cause corrosion even if they come into contact with the surrounding activated carbon, effectively ensuring the fixing strength of the corrosion-resistant bed plate 3, thereby further improving the service life of the adsorption tower.

[0038] Furthermore, the support frame 2 has several assembled profiles 22 arranged at intervals in the vertical direction. These assembled profiles 22 are horizontally positioned, with their two ends abutting against adjacent corrosion-resistant bed plates 3 to form supports. The assembled profiles 22 are fixed vertically in the support frame 2, with their two ends abutting against the corrosion-resistant bed plates 3. This provides support to the middle section of the corrosion-resistant bed plates 3, compensating for the weakness in the middle section due to the outer edges being clamped by the pressure strips 4. This effectively reduces the risk of collapse, thereby further extending the service life of the adsorption tower. Preferably, the assembled profiles 22 are entirely made of fiberglass. The use of fiberglass for the assembled profiles 22 effectively prevents corrosion from contact with activated carbon, thus preventing a reduction in support strength.

[0039] Furthermore, all corrosion-resistant bed plates 3 are vertically arranged, and each bed 21 at the top of the tower shell 1 is provided with an activated carbon filling port 14, and each bed 21 at the bottom of the tower shell 1 is provided with an activated carbon discharge port 15. All corrosion-resistant bed plates 3 in this application are vertically arranged with activated carbon filling ports 14 and discharge ports 15 in the vertical direction. This design facilitates the filling and replacement of activated carbon. In particular, the vertical arrangement allows corrosive liquids to flow vertically out through the activated carbon discharge ports 15, effectively preventing accumulation inside the tower shell 1 and causing corrosion. It also allows observers to visually observe when the activated carbon reaches saturation and needs replacement. This design further extends the service life of the adsorption tower.

[0040] Furthermore, the support frame 2 comprises several square tubular fiberglass profiles, which are used to construct a simple square frame shape. The support frame 2 of this application is also entirely made of fiberglass profiles. Even if corrosive liquids or corrosive activated carbon come into contact with it, it will not cause corrosion. The overall adsorption tower has excellent corrosion resistance, resulting in a longer service life.
