Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas treatment devices, and in particular relates to an activated carbon adsorber for hazardous waste incineration flue gas. Background Technology

[0002] With the rapid pace of social development, the sources of hazardous waste are becoming increasingly diverse, and its output is on the rise. This type of waste is complex in composition, highly potentially toxic, and difficult to treat. Among various disposal methods, incineration, with its ability to reduce volume and contribute to harmlessness, has become one of the most widely used methods in the field of hazardous waste treatment. Activated carbon, with its porous structure and surface functional groups, can physically and chemically adsorb pollutants in flue gas. Specifically, it can efficiently capture dioxins and adsorb heavy metals (such as mercury and its compounds) from hazardous waste incineration flue gas, and can also assist in the removal of acidic gases, meeting environmental standards for ultra-low emissions of pollutants. Therefore, activated carbon adsorption has become one of the key links in the incineration process for treating hazardous waste.

[0003] Traditional activated carbon adsorption devices typically adsorb most of the toxic substances in flue gas generated from hazardous waste incineration by having the flue gas pass vertically through the adsorption plate. However, this vertical passage of the flue gas through the adsorption plate can cause the activated carbon at the flue gas inlet to become saturated prematurely, while the activated carbon at the edges remains far from saturated. This results in premature failure of the activated carbon in certain areas, significantly impacting the lifespan of the adsorption plate. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing an activated carbon adsorber for hazardous waste incineration flue gas, which improves the uniformity of flue gas adsorption by the activated carbon on the adsorption plate and extends the service life of the adsorption plate.

[0005] In view of this, the present invention provides an activated carbon adsorber for hazardous waste incineration flue gas, comprising:

[0006] The box has a first air inlet connected to an air inlet pipe and a first air outlet connected to an air outlet pipe at both ends, and multiple horizontally arranged adsorption plates are installed inside the box.

[0007] The bracket is installed inside the box and is used to support the installation of multiple adsorption plates. A second air inlet is formed on the upper end face of each adsorption plate, and a second air outlet is formed on the lower end face.

[0008] An inclined plate is installed on the bracket, and forms an air inlet chamber and an air outlet chamber between the upper and lower end faces of the adsorption plate, respectively.

[0009] The inclined plate is used to guide the flue gas to the adsorption plate at an angle, and the size of the air inlet chamber gradually decreases along the side away from the second air inlet, while the size of the air outlet chamber gradually increases along the side closer to the second air outlet.

[0010] In the above technical solution, further:

[0011] The adsorption plate includes an upper clamping plate and a lower clamping plate, and a plurality of equally spaced partitions are provided between the upper clamping plate and the lower clamping plate, and the partitions are honeycomb panels;

[0012] Each pair of adjacent partitions is equipped with an adsorption cylinder, which is filled with activated carbon and has multiple air vents.

[0013] In the above technical solution, further:

[0014] The two ends of the adsorption cylinder correspond to the second air inlet and the second air outlet, respectively.

[0015] In the above technical solution, further:

[0016] An adsorption cylinder is equipped with a winding body, which is used to keep the activated carbon located on the side of the winding body near the inner wall of the adsorption cylinder on the inner wall of the adsorption cylinder.

[0017] The wound body is filled with activated carbon on both sides of the adsorption cylinder radially.

[0018] In the above technical solution, further:

[0019] Honeycomb support plates are provided between the adsorption cylinder and the upper and lower clamping plates.

[0020] In the above technical solution, further:

[0021] A metal wire mesh is installed between the adsorption cylinder and the honeycomb support plate.

[0022] In the above technical solution, further:

[0023] The upper and lower clamping plates are respectively provided with ring-shaped support parts, which are connected by bolts, and the ring-shaped support parts are provided with reinforcing ribs for supporting the honeycomb support plate.

[0024] In the above technical solution, further:

[0025] The adsorption plate, the support, and the inclined plate are arranged symmetrically in two sets inside the box.

[0026] The beneficial effects of this utility model are as follows:

[0027] 1. By placing the adsorption plate horizontally and setting an inclined plate to guide the flue gas, the flue gas enters the adsorption plate at an angle. Due to the setting of the inclined plate, the size of the air inlet chamber gradually decreases along the side away from the second air inlet, which effectively improves the uniformity of activated carbon adsorption in various parts of the adsorption plate, avoids large deviations in the uniformity of activated carbon use in various parts of the adsorption plate, and prevents premature failure of local activated carbon, thus extending the service life of the adsorption plate and ensuring the adsorption effect of activated carbon on toxic substances in flue gas.

[0028] 2. By using multiple adsorption cylinders inside the adsorption plate and filling them with activated carbon, the structural stability of the activated carbon inside the adsorption plate is ensured. Furthermore, the upper clamping plate, lower clamping plate, and partition plate further enhance the structural stability of the adsorption cylinders, thereby improving the structural stability of the activated carbon inside the adsorption plate.

[0029] 3. By aligning the two ends of the adsorption cylinder with the second air inlet and the second air outlet respectively, and by setting a winding body inside the adsorption cylinder, the structural stability inside the adsorption cylinder of the activated carbon can be further improved, ensuring the adsorption effect and adsorption uniformity, and avoiding gaps that would result in some flue gas not being effectively adsorbed.

[0030] 4. The honeycomb support plate can improve the structural strength and stability of the adsorption plate, and together with the partition plate, it can effectively ensure the installation stability of the adsorption cylinder and the stability of activated carbon adsorption.

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] Example 1:

[0040] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, comprising:

[0041] The box 1 has a first air inlet 3 connected to an air inlet pipe 2 and a first air outlet 5 connected to an air outlet pipe 4 at both ends, and multiple horizontally arranged adsorption plates 6 are installed inside the box 1.

[0042] The bracket 7 is installed inside the housing 1 and is used to support the installation of multiple adsorption plates 6. A second air inlet 8 is formed on the upper end face of each adsorption plate 6, and a second air outlet 9 is formed on the lower end face.

[0043] Inclined plate 10 is mounted on bracket 7 and forms an air inlet chamber 11 and an air outlet chamber 12 between the upper end face and the lower end face of adsorption plate 6, respectively.

[0044] The inclined plate 10 is used to guide the flue gas to the adsorption plate 6 at an angle, and the size of the air inlet chamber 11 gradually decreases along the side away from the second air inlet 8, while the air outlet chamber 12 gradually increases along the side close to the second air outlet 9.

[0045] Meanwhile, the bracket 7 may include an L-shaped support portion 600, which is used to support both ends of the adsorption plate 6. The support portion 600 and the inclined plate 10 may be integrated, and bolts may be used to lock them to the inner wall of the box 1.

[0046] Furthermore, a switch door can be provided on the side of the box 1, and a sealing strip is provided between the switch door and the box 1, so as to facilitate the disassembly and replacement of the adsorption plate 6.

[0047] As can be seen from this embodiment, by placing the adsorption plate 6 horizontally and setting the inclined plate 10 to guide the flue gas, the flue gas enters the adsorption plate 6 at an angle. With the setting of the inclined plate 10, the size of the air inlet cavity 11 gradually decreases along the side away from the second air inlet 8, which effectively improves the uniformity of adsorption by the activated carbon 64 in various parts of the adsorption plate 6, avoids large deviations in the uniformity of the use of activated carbon 64 in various parts of the adsorption plate 6, which would lead to premature failure of local activated carbon 64, prolongs the service life of the adsorption plate 6, and can ensure the adsorption effect of activated carbon 64 on toxic substances in flue gas.

[0048] Specifically, the inclined plate 10 guides the flue gas so that it does not enter the adsorption plate 6 in a vertical direction, thereby making the flue gas move parallel to the surface of the adsorption plate 6, thus ensuring the uniformity of the flue gas entering the adsorption plate 6.

[0049] Meanwhile, the formation of the air inlet chamber 11 and the size of the air inlet chamber 11 gradually decrease along the side away from the second air inlet 8, thereby preventing too much flue gas from entering the adsorption plate 6 away from the second air inlet 8 due to the inertia of the flow. This can further improve the uniformity of flue gas entering the adsorption plate 6, ensure the uniformity of the use of activated carbon 64 in the adsorption plate 6, avoid premature local failure, and extend the service life.

[0050] The formation of the exhaust chamber 12 and the gradual increase in size of the exhaust chamber 12 along the side close to the second exhaust port 9 can ensure the exhaust efficiency of the flue gas after passing through the adsorption plate 6, thus ensuring the adsorption efficiency.

[0051] Example 2:

[0052] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0053] The adsorption plate 6 includes an upper clamping plate 60 and a lower clamping plate 61, and a plurality of equally spaced partitions 62 are provided between the upper clamping plate 60 and the lower clamping plate 61, and the partitions 62 are honeycomb panels.

[0054] Each pair of adjacent partitions 62 is equipped with an adsorption cylinder 63, and the adsorption cylinder 63 is filled with activated carbon 64. The adsorption cylinder 63 is provided with multiple air vents 65.

[0055] As can be seen from this embodiment, by using multiple adsorption cylinders 63 inside the adsorption plate 6 and filling the adsorption cylinders 63 with activated carbon 64, the structural stability of the activated carbon 64 inside the adsorption plate 6 is ensured. Furthermore, the arrangement of the upper clamping plate 60, the lower clamping plate 61, and the partition plate 62 improves the structural stability of the adsorption cylinders 63, thereby further improving the structural stability of the activated carbon 64 inside the adsorption plate 6.

[0056] By using a honeycomb plate for the baffle 62, the flue gas can flow horizontally in multiple directions after entering the adsorption plate 6, further improving the uniformity of adsorption by the activated carbon 64 inside the adsorption plate 6.

[0057] Example 3:

[0058] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0059] The two ends of the adsorption cylinder 63 correspond to the second air inlet 8 and the second air outlet 9, respectively.

[0060] As can be seen from this embodiment, the inertial direction of the horizontal flow of flue gas is the same as the axial direction of the adsorption cylinder 63, which allows the flue gas to come into more contact with the activated carbon 64 inside the adsorption cylinder 63, thereby effectively improving the adsorption effect.

[0061] Example 4:

[0062] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0063] An adsorption cylinder 63 is equipped with a winding body 66, which is used to hold the activated carbon 64 located on the side of the winding body 66 near the inner wall of the adsorption cylinder 63 on the inner wall of the adsorption cylinder 63.

[0064] The wound body 66 is filled with activated carbon 64 on both sides of the adsorption cylinder 63 radially, and multiple through holes 67 are opened on the wound body 66.

[0065] Meanwhile, the winding body 66 can be a metal sheet with multiple through holes 67, and the activated carbon 64 cannot pass through the through holes 67.

[0066] As can be seen from this embodiment, by setting the winding body 66, a layer of activated carbon 64 can always be maintained on the inner wall of the adsorption cylinder 63, thereby avoiding the generation of gaps and causing the flue gas to pass through the adsorption plate 6 upon contact with the activated carbon 64, which can effectively ensure the adsorption effect.

[0067] Example 5:

[0068] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0069] A honeycomb support plate 68 is provided between the adsorption cylinder 63 and the upper clamping plate 60 and the lower clamping plate 61.

[0070] As can be seen from this embodiment, the installation stability and structural strength of the adsorption cylinder 63 inside the adsorption plate 6 are effectively improved by setting the honeycomb support plate 68.

[0071] Example 6:

[0072] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0073] A metal wire mesh 69 is provided between the adsorption cylinder 63 and the honeycomb support plate 68.

[0074] As can be seen from this embodiment, the installation stability of the adsorption cylinder 63 can be further improved by setting the metal wire mesh 69, and it can also play a certain role in intercepting particles in the flue gas. At the same time, it can ensure that even if the activated carbon 64 particles fall out of the adsorption cylinder 63, they can be confined between two adjacent partitions 62, providing double protection.

[0075] Example 7:

[0076] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0077] The upper clamping plate 60 and the lower clamping plate 61 are respectively provided with annular support portions 600, which are connected by bolts, and the annular support portions 600 are provided with reinforcing ribs 601 for supporting the honeycomb support plate 68.

[0078] As can be seen from this embodiment, the ring-shaped support 600 and the bolt connection can improve the ease of installation and disassembly between the upper clamping plate 60 and the lower clamping plate 61, thereby improving the ease of replacement of the adsorption cylinder 63 and the ease of replacement of the internal activated carbon 64.

[0079] The reinforcing ribs 601 on the support 600 can further improve the structural strength of the honeycomb support plate 68 and ensure the structural stability of the adsorption plate 6.

[0080] Example 8:

[0081] This embodiment provides an activated carbon adsorber for hazardous waste incineration flue gas, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0082] The adsorption plate 6, the support 7, and the inclined plate 10 are arranged symmetrically in two sets inside the box 1.

[0083] As can be seen from this embodiment, by setting two sets, the flue gas can be adsorbed twice, ensuring the overall adsorption rate of harmful substances in the flue gas, reducing the leakage rate of harmful substances, and the two sets are symmetrically arranged, that is, the second air outlet 9 of the first set can correspond to the second air inlet 8 of the second set, ensuring the movement inertia of the flue gas in the horizontal direction of the second set of adsorption plates 6, and ensuring the adsorption effect and uniformity of the second set of activated carbon 64.

[0084] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
