[0027] Example 1

[0028] Due to the relatively limited applicability of existing activated carbon adsorption boxes and the lack of internal airflow dispersion, an activated carbon adsorption box with dispersed airflow and broader applicability was designed. The specific scheme is as follows:

[0029] like Figure 1As shown, a high-efficiency activated carbon adsorption box includes: a box structure 1, which contains multiple detachable placement boxes 2. The placement boxes 2 contain double layers of activated carbon of different specifications to ensure adsorption efficiency. The box structure 1 has an air inlet 101 and an air outlet 102 at both ends. The air inlet 101 is equipped with a heat exchange pipe 4, which can be used for heat exchange and cooling of waste gas. The top of the heat exchange pipe 4 is also equipped with a spray pipe 401. A honeycomb guide component is provided between the heat exchange pipe 4 and the placement box 2 to uniformly disperse the airflow.

[0030] The placement box 2 adopts a drawer-type structure, with a handle installed on the outer side for easy removal. Specifically, the main frame of the placement box 2 is made of high-quality cold-rolled steel plate after rust prevention treatment, and the surface of the placement box 2 is treated with electrostatic powder coating, which has excellent corrosion resistance to adapt to the environment of waste gas treatment. The exterior of the placement box 2 is equipped with an ergonomic curved handle 203 for easy gripping.

[0031] In this embodiment, the internal space of the placement box 2 is a double-layer structure, used to place activated carbon of different sizes. The upper layer is the first placement layer 201, and the lower layer is the second placement layer 202. Specifically, the first placement layer 201 is used to place activated carbon particles with a particle size of 4-8 mesh, and the second placement layer 202 is used to place columnar or honeycomb activated carbon with a size of 3cm-5cm. Through physical layering, a multi-level adsorption effect is achieved.

[0032] The front of the enclosure structure 1 has a viewing window, which is located on the layer facing the air intake of the placement box 2. It is made of thick tempered glass, which facilitates real-time observation of the internal activated carbon status. Each placement box 2 has a rotating latch 204 on both sides to ensure that the placement box 2 is installed securely.

[0033] The top of the enclosure structure 1 is equipped with a removable top plate, which, when removed, allows the enclosure structure 1 to be opened.

[0034] The box structure 1 has a support structure 6 inside, which is used to place the box 2, which is slidably connected to the support structure 6. The support structure 6 is a C-shaped slide, and multiple pulleys are installed in the slide, allowing the box 2 to be smoothly moved out or pushed in. The internal structure of the box adopts a reinforced support frame structure, and the main body is formed by bending cold-rolled steel plate, with an overall C-shaped cross-section. Multiple nylon pulleys are installed at equal intervals in each slide.

[0035] The placement box 2 has matching guide rails on both sides, and the end of the slide is equipped with a silicone shock-absorbing pad, which can effectively absorb the impact force when the drawer is in place, ensuring smooth and reliable operation and improving ease of operation.

[0036] A heat insulation plate 105 is provided between the heat exchange tube 4 and the honeycomb flow guide component to isolate the temperature and avoid affecting the adsorption of activated carbon. A vent 1051 is provided in the middle of the heat insulation plate 105 for the passage of exhaust gas. Specifically, the heat insulation plate 105 adopts a three-layer composite structure design: the outer layer is a stainless steel protective plate, the middle layer is filled with ceramic fiber heat insulation cotton, and the inner layer is a high temperature resistant aluminum plate, which can effectively block the conduction of high temperature above 300℃ and ensure that the temperature of the activated carbon adsorption zone at the rear end is stable below 50℃.

[0037] On the housing structure 1 corresponding to the heat exchange tube 4 and the honeycomb flow guide component, there is an openable cover plate 5. The cover plate 5 and the housing structure 1 are also provided with sealing gaskets 106 to prevent exhaust gas leakage. Opening the cover plate 5 can facilitate the disassembly and assembly of the heat exchange tube 4 and the honeycomb flow guide component.

[0038] The honeycomb airflow guiding components are arranged in an upper, middle, and lower configuration, specifically including a first honeycomb airflow guiding plate 301, a second honeycomb airflow guiding plate 302, and a third honeycomb airflow guiding plate 303. The airflow outlet directions of the first honeycomb airflow guiding plate 301 and the third honeycomb airflow guiding plate 303 are tilted in corresponding directions, allowing the exhaust gas to flow in the upper, middle, and lower directions respectively. Specifically, the first airflow guiding plate is designed with a 15° upward tilt angle, which can guide approximately 35% of the airflow to the upper space of the housing; the second airflow guiding plate is kept horizontally, ensuring that approximately 30% of the airflow remains horizontal; and the third airflow guiding plate is designed with a 15° downward tilt angle, guiding the remaining 35% of the airflow to the lower part of the housing. This unique three-dimensional airflow guiding design, combined with precise tilt angle control, can achieve a three-dimensional and uniform distribution of airflow, with airflow velocity differences controlled within ±5%.

[0039] A temperature sensor is installed inside the housing structure 1 at the location of the heat exchange tube 4 to sense the internal temperature. Specifically, the temperature sensor detects the temperature, and when the temperature exceeds a preset value, the temperature sensor sends a signal to the control unit. The control unit then controls the flow rate of the heat exchange medium in the heat exchange tube 4 to improve heat exchange efficiency. In addition, the spray pipe 401 can be opened for coordinated cooling, which can not only cool the exhaust gas but also cool the outside of the heat exchange tube 4, ensuring heat exchange efficiency.

[0040] The spray pipe 401 is connected to a water pump 1032, which can transport cooling water. Specifically, a V-shaped water collection tank 103 is provided at the bottom of the heat exchange section. The water pump 1032 is connected to the water collection tank 103. An inverted L-shaped baffle is provided on the inner wall of the water collection tank 103 near the water pump 1032, so that the water drawn by the water pump 1032 is relatively clean and can be reused for spray cooling. A drain outlet 104 is also provided at the bottom of the water collection tank 103, which can periodically discharge sewage.

[0041] A sealing gasket 106 is provided at the closed position of the placement box 2 and the box structure 1 to prevent the leakage of exhaust gas. The sealing gasket 106 fits snugly with the box structure 1. After the placement box 2 is installed, the front edge of the placement box 2 is precision machined to form a flat sealing strip covering the position of the sealing gasket 106. The front edge of the placement box 2 can fit tightly with the front side of the sealing gasket 106 to achieve the sealing function.

[0042] Working principle:

[0043] The exhaust gas enters the housing structure 1 through the air inlet 101. The heat exchange medium in the heat exchange tube 4 flows and exchanges heat with the hot exhaust gas, thereby cooling the hot exhaust gas. The cooled exhaust gas flows through the heat insulation plate 105 to the honeycomb guide plate. The exhaust gas is divided into three airflows, which flow to the upper, middle and lower parts of the housing structure 1 respectively. After being adsorbed by activated carbon, it flows towards the air outlet 102.

[0044] When the temperature sensor detects that the temperature of the heat exchange part is high, the external control unit automatically controls the flow of the heat exchange medium to accelerate. The spray pipe 401 can also be turned on to spray the heat exchange part, which cools the hot exhaust gas and the outside of the heat exchange pipe 4. The heat insulation plate 105 can isolate the temperature at this location and prevent the activated carbon from being too hot and causing desorption problems.

[0045] In summary, the adsorption box of this solution improves the efficiency of waste gas treatment, extends the activated carbon replacement cycle, and enhances its applicability. It can be used for the treatment of high-temperature waste gas without the need to reconstruct the entire adsorption box, resulting in relatively lower modification costs and facilitating enterprise development.

[0046] Example 2

[0047] In this embodiment, the structure of the activated carbon adsorption box is basically the same as that in Embodiment 1. The difference is that the middle structure of the adsorption box is composed of multiple square tubular structures fixedly connected. The square tubular structures can be added or removed as needed to increase or decrease the length of the adsorption box. Increasing the length can provide more space inside for the installation of the box 2, eliminating the need to manufacture a larger adsorption box. This can save equipment costs to a certain extent in terms of usage costs.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
