Description

Technical Field

[0001] This utility model relates to the field of gas treatment technology, specifically to an activated carbon adsorption tower for gas treatment. Background Technology

[0002] Activated carbon adsorption towers are a common type of waste gas treatment equipment. Their principle is to use activated carbon to adsorb harmful substances in the gas. However, after the waste gas enters the adsorption tower, due to the uneven distribution of the airflow, the activated carbon in some areas may become saturated, while the activated carbon in other areas is not fully utilized, resulting in a decrease in adsorption efficiency. In addition, for some high-concentration harmful gases, direct contact with activated carbon may quickly occupy the adsorption sites of the activated carbon, making it impossible for subsequent gases to be effectively adsorbed and treated.

[0003] Therefore, in order to solve the problem of low waste gas treatment efficiency caused by uneven airflow distribution and high concentration in the adsorption tower, it is necessary to propose an activated carbon adsorption tower for gas treatment. Utility Model Content

[0004] The purpose of this invention is to provide an activated carbon adsorption tower for gas treatment. The tower can effectively guide the waste gas through the air guide plate, so that the airflow is evenly distributed and flows fully through the activated carbon layer. The gas is diluted by the dilution component before it comes into contact with the activated carbon layer, so as to prevent the waste gas from rapidly occupying the adsorption sites of the activated carbon and slow down the saturation rate of the activated carbon, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An activated carbon adsorption tower for gas treatment includes:

[0007] The enclosure has an air inlet on one side and an air outlet on the other side.

[0008] Several first and second sieve plates are available, both of which can be detached and installed inside the box, and the first and second sieve plates are distributed sequentially along the airflow direction;

[0009] The activated carbon layer is detachably installed inside the second sieve plate, and the activated carbon layer adopts a composite structure with a filler layer in the middle.

[0010] The air guide plate is fixedly installed inside the box and located between two adjacent screen plates;

[0011] The dilution component is fixedly installed on the air guide plate and includes several dilution plates. Each dilution plate has multiple air holes on its surface, and the diameter of the air holes gradually decreases along the airflow direction.

[0012] Preferably, both the air inlet and the air outlet are circular, and their edges are provided with flange structures.

[0013] Preferably, the air guide plate is also provided with air holes at the front end of the dilution component, and the diameter of the holes on the air guide plate is larger than that on the dilution plate.

[0014] Preferably, the air outlet of the dilution component is directly opposite the activated carbon layer, and the filtration area of ​​the activated carbon layer covers the entire air outlet.

[0015] Preferably, the first and second sieve plates are movably installed on the upper part of the box using a drawer-type structure, and both the first and second sieve plates are provided with a sealing plate on their tops.

[0016] Preferably, the first screen plate is located at the air inlet, and a filter material made of polyester synthetic fiber or glass fiber is installed inside it.

[0017] Preferably, the activated carbon layer is tightly engaged with the second sieve plate via a slot.

[0018] Preferably, a baffle is provided between the activated carbon layer and the filler layer to allow gas to pass through.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The activated carbon adsorption tower used for gas treatment can effectively guide the waste gas through the setting of the air guide plate, so that the airflow is evenly distributed in the adsorption tower. This avoids the situation where some activated carbon is saturated due to uneven airflow distribution while other areas are not fully utilized. This allows the entire activated carbon layer to fully participate in adsorption, significantly improving the adsorption efficiency.

[0021] 2. The activated carbon adsorption tower used for gas treatment dilutes the gas before it comes into contact with the activated carbon layer through a dilution component. This slows down the rapid occupation of the activated carbon adsorption sites by high-concentration harmful gases, allowing the activated carbon to more effectively adsorb subsequent gases, further improving adsorption efficiency and extending the effective service life of the activated carbon.

[0027] Please see Figures 1-4 An activated carbon adsorption tower for gas treatment, comprising:

[0028] The housing 1 has an air inlet 2 on one side and an air outlet 3 on the other side;

[0029] Several first sieve plates 4 and second sieve plates 5 can be detached and installed inside the housing 1, and the first sieve plates 4 and second sieve plates 5 are distributed sequentially along the airflow direction;

[0030] The activated carbon layer 51 is detachably installed inside the second sieve plate 5, and the activated carbon layer 51 adopts a composite structure, with a filler layer 52 in the middle.

[0031] The air guide plate 6 is fixedly installed inside the housing 1 and is located between two adjacent screen plates;

[0032] The dilution component 61 is fixedly installed on the air guide plate 6 and includes several dilution plates 611. Each dilution plate 611 has multiple air holes 612 on its surface, and the diameter of the air holes 612 gradually decreases along the airflow direction.

[0033] The first sieve plate 4 and the second sieve plate 5 can be detached and installed inside the housing 1, which facilitates maintenance, replacement or cleaning. The arrangement of the sieve plates along the airflow direction allows the gas to pass through each sieve plate in sequence, thereby achieving multi-layer adsorption and filtration effects and improving the efficiency of gas treatment.

[0034] The activated carbon layer 51 is detachably installed inside the second sieve plate 5, which facilitates the replacement of saturated activated carbon and ensures the continuity of adsorption effect. It adopts a composite structure, and the filler layer 52 set in the middle can further enhance the adsorption capacity and stability of the activated carbon layer 51. The filler in the filler layer 52 may be some materials with good adsorption performance or that can work synergistically with activated carbon, such as zeolite molecular sieves, activated alumina, etc. Through the combination of different materials, more efficient adsorption and removal of different pollutants can be achieved.

[0035] The air guide plate 6 is fixedly installed between two adjacent sieve plates inside the box 1, which plays the role of guiding the airflow direction and distribution, so that the gas can pass through the activated carbon layer 51 evenly, avoiding the situation that the local airflow speed is too fast or too slow, thereby improving the adsorption efficiency and uniformity of the entire adsorption tower.

[0036] The design of the dilution component 61 allows the gas to gradually diffuse and dilute as the airflow passes through, reducing the local gas concentration and preventing high-concentration pollutants from causing the activated carbon layer 51 to become saturated too quickly. It also helps to improve the adaptability of the entire adsorption tower to different concentrations of waste gas, allowing the gas to be more evenly distributed before entering the next stage of adsorption treatment, thereby further improving the adsorption effect.

[0037] Please see Figures 1-2 Both the air inlet 2 and the air outlet 3 are circular, and their edges are provided with flange structures.

[0038] The flange structure provides a solid connection base for the air inlet 2 and the air outlet 3. Through the bolt holes on the flange, bolts and nuts can be used to connect the adsorption tower to other pipelines or close equipment, ensuring the firmness and stability of the connection. It can withstand the pressure and vibration generated during gas flow, and prevent the connection from loosening or falling off, thereby ensuring the safe operation of the adsorption tower system.

[0039] Furthermore, flange edges are usually used in conjunction with sealing gaskets, such as rubber gaskets or asbestos gaskets. When the flange connection is tightened, the sealing gasket is compressed and fills the tiny gaps between the flanges, forming a reliable sealing barrier that effectively prevents gas leakage and ensures that all gas passes through the adsorption tower for treatment, thereby improving the effect and efficiency of gas treatment.

[0040] Please see Figure 4 The air guide plate 6 is located at the front end of the dilution component 61 and also has air holes 612. The diameter of the holes on the air guide plate 6 is larger than the diameter of the holes on the dilution plate 611.

[0041] The air guide plate 6 has large-diameter air holes 612 located at the front end of the dilution component 61, which can initially guide and divert the gas entering the adsorption tower. The air holes 612 on the dilution plate 611 have smaller diameters and more. After passing through the air guide plate 6, the gas is further diverted and dispersed by the dilution plate 611, which can distribute it more evenly in the adsorption tower and make full contact with the activated carbon layer 51. At the same time, it can also dilute high concentrations of harmful gases, reduce local gas concentrations, and avoid causing the activated carbon layer 51 to become saturated too quickly.

[0042] Please see Figure 4 The air outlet of the dilution component 61 is directly facing the activated carbon layer 51, and the filtration area of ​​the activated carbon layer 51 covers the entire air outlet.

[0043] This design allows the diluted gas to be evenly sprayed onto the surface of the activated carbon layer 51, ensuring that the gas sprayed from the air outlet can fully contact the activated carbon layer 51, and that no untreated gas passes through directly, thereby improving the uniformity and efficiency of gas treatment.

[0044] Please see Figures 1-2 The first sieve plate 4 and the second sieve plate 5 are movably installed on the upper part of the box body 1 using a drawer-type structure, and both the top of the first sieve plate 4 and the second sieve plate 5 are provided with a sealing plate.

[0045] Among them, the drawer-type structure allows the sieve plate to be easily pulled out and pushed in from the top of the box 1 like a drawer, without disassembling other parts, which facilitates the installation, maintenance or replacement of the sieve plate;

[0046] The sealing plate can effectively prevent gas from leaking from the gap between the screen plate and the box 1, ensuring that all gas passes through the screen plate for filtration and adsorption. The sealing plate is usually made of elastic material or sealing strip, which can fit tightly against the screen plate and the box 1 to improve the sealing effect.

[0047] Please see Figures 1-2 The first screen plate 4 is located at the air inlet 2, and a filter material made of polyester synthetic fiber or glass fiber is installed inside it.

[0048] Polyester synthetic fiber has good filtration performance, chemical stability and mechanical strength. It can effectively intercept particulate matter, dust and some harmful gases in the gas, play a preliminary filtration role, remove larger particulate impurities in the gas, reduce the burden on the subsequent activated carbon layer 51 and extend the service life of the activated carbon.

[0049] Please see Figure 4 The activated carbon layer 51 is tightly connected to the second sieve plate 5 through a slot, and a partition is provided between the activated carbon layer 51 and the packing layer 52 to allow gas to pass through.

[0050] The slot design allows the activated carbon layer 51 to be tightly engaged with the second sieve plate 5, ensuring that the activated carbon layer 51 will not shift or loosen during gas flow, thereby ensuring the consistency of adsorption effect. At the same time, the slot structure facilitates the installation and disassembly of the activated carbon layer 51.

[0051] The partition can prevent filler particles in the filler layer 52 from entering the activated carbon layer 51, thus avoiding blockage or contamination of the activated carbon layer 51 by the filler particles.

[0052] Working principle: In the operation of this activated carbon adsorption tower for gas treatment, the waste gas first enters the housing 1 from the air inlet 2, and then reaches the first screen plate 4. The first screen plate 4 effectively intercepts particulate matter, dust and some harmful gases in the gas, playing a preliminary filtration role.

[0053] After initial filtration, the gas continues to pass through multiple guide plates 6 and the second screen plate 5 in sequence along the airflow direction. The upper end of the guide plate 6 is provided with air holes 612, which can initially guide and divert the gas. The gas passing through the guide plate 6 then enters the dilution component 61 for further diversion and dispersion. This process can not only make the gas evenly distributed in the adsorption tower, but also dilute high concentrations of harmful gases.

[0054] The diluted waste gas is evenly sprayed onto the surface of the activated carbon layer 51, making full contact with the activated carbon layer 51. The activated carbon layer 51 is also equipped with a filler layer 52, which can further improve the adsorption effect.

[0055] The gas has been effectively purified after deep adsorption treatment by the activated carbon layer 51. Finally, the purified gas is discharged from the outlet 3 on the other side of the adsorption tower.
