Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment environmental protection equipment, and particularly relates to an adsorption and regeneration box filled with granular activated carbon and an adsorption and regeneration system. Background Technique

[0002] Waste gas treatment is an essential link in industrial and commercial operations to ensure that the discharged gas meets environmental protection standards and reduces the impact on the environment. In this process, the adsorption box plays an important role. The adsorption box is filled with efficient adsorption materials, which can capture volatile organic compounds (VOCs) and other harmful substances in the waste gas to achieve the purification of the waste gas.

[0003] Currently, activated carbon and zeolite molecular sieves are the mainstream adsorption materials in the environmental protection field. Zeolite molecular sieves are favored for their small pressure loss, good adsorption performance, and easy regeneration characteristics. However, due to the high cost of zeolite molecular sieves, the overall material and equipment investment cost of the adsorption box increases. In contrast, activated carbon not only has good adsorption capacity, wide practicability, but also is more economical in price, meeting the national first-class emission standard for waste gas. The low cost of activated carbon makes it more valuable in the environmental protection market.

[0004] Activated carbon can be divided into honeycomb activated carbon and granular activated carbon according to its shape. Honeycomb activated carbon, with its unique honeycomb structure, provides uniform gas flow distribution, small pressure loss, large geometric surface area, and good abrasion resistance and regeneration ability. However, the binder added during the forming process of honeycomb activated carbon blocks some pores of the activated carbon, reducing its adsorption capacity and unable to meet the increasingly stringent requirements for waste gas treatment. Therefore, the adsorption effect of honeycomb activated carbon is far lower than that of zeolite molecular sieves, and it has no advantage in treating medium- and high-concentration waste gas. Granular activated carbon itself is a regenerable activated carbon, with advantages such as a large specific surface area, developed pore structure, high mechanical strength, acid and alkali resistance, and stable properties, and can provide good adsorption performance.

[0005] However, the application of granular activated carbon in the adsorption box has some limitations: when too much granular activated carbon accumulates, due to the uneven pore structure inside the fixed bed caused by its disordered accumulation, it will increase the resistance when air or fluid passes through the bed layer, resulting in significant pressure loss. This resistance not only affects the hydrodynamic characteristics, but also may cause local accumulation of volatile organic compounds (VOCs) during the regeneration process, thereby reducing the regeneration efficiency of the granular activated carbon, and even causing a fire, which in turn affects the recycling use of the adsorption box.

[0006] To overcome the above problems, it is necessary to optimize the distribution of the adsorption material and improve the structural design of the bed layer, so that the adsorption box can simultaneously ensure the adsorption performance and regeneration performance, and can realize the cyclic regeneration use of the adsorption box, thereby effectively saving costs. Summary of the Invention

[0007] In view of the above, the present utility model provides an adsorption and regeneration box and an adsorption and regeneration system for loading granular activated carbon. The adsorption and regeneration box uses granular activated carbon as an adsorption material. Through the granular activated carbon module, the granular activated carbon has the characteristics of good adsorption performance, small resistance of the bed layer, uniform air flow distribution, and recyclable regeneration, and can meet the functions of cyclic adsorption and regeneration of waste gas.

[0054] The present utility model will be described in detail below with reference to the accompanying drawings and by way of examples.

[0055] Example 1:

[0056] This example provides an adsorption and regeneration tank loaded with granular activated carbon, using granular activated carbon as the adsorption material.

[0057] The adsorption and regeneration tank 1 is used for adsorbing and desorbing volatile organic compounds (VOCs) in the waste gas.

[0058] As Figures 1 to 3 shown, the adsorption and regeneration tank 1 includes: a housing 101, a hatch 102, a sealing ring, a plurality of lug supports, a plurality of grille modules, a plurality of granular activated carbon modules, two gas distributors 105 and two tees 107.

[0059] The housing 101 is narrow at both the upper and lower ends and wide in the middle. The housing 101 includes: a rectangular parallelepiped shell with openings at both the upper and lower ends, two frustum-shaped bodies, and a thermal insulation layer. The large ends of the two frustum-shaped bodies are respectively butted against the two open ends of the rectangular parallelepiped shell. Each side wall of the rectangular parallelepiped shell is composed of two plate layers stacked in the thickness direction. There is a gap between the two plates, and the thermal insulation layer is placed in this gap. In this example, the thickness of the thermal insulation layer is preferably 5 cm. The thermal insulation layer is made of aluminum silicate fiber cotton or rock wool. The size of the housing 101 is determined according to the size and quantity of the encapsulated modules.

[0060] The two tees 107 are respectively and correspondingly installed at the small-mouth ends of the two frustum-shaped bodies of the housing 101. Each tee 107 is of a T-shaped structure, with the vertically penetrating pipe as the main pipe and the pipe extending laterally along the main pipe as the side pipe. In each tee 107, one end of the main pipe serves as the adsorption interface, and the other end of the main pipe serves as the connection interface. In each tee 107, the end of the side pipe serves as the desorption interface. Let the adsorption interface and desorption interface of the tee 107 located above be the adsorption interface a and the desorption interface a respectively, and let the adsorption interface and desorption interface of the tee 107 located below be the adsorption interface b and the desorption interface b respectively.

[0061] The two gas distributors 105 are respectively fixedly connected to the inner wall surfaces of the two frustum-shaped bodies. The plane where each gas distributor 105 is located is perpendicular to the flow direction of the gas. As Figure 7As shown, the gas distributor 105 includes a windward surface and a leeward surface. A number of convex structures are machined on the leeward surface. In the gas distributor 105, gas flows in through the windward surface and out through the leeward surface. The gas is evenly distributed through the number of convex structures on the leeward surface. Among the two gas distributors 105, the windward surface of the upper gas distributor 105 faces upward, and the windward surface of the lower gas distributor 105 faces downward. That is, the upper gas distributor 105 is used to evenly distribute the airflow flowing into the adsorption regeneration tank 1 from the adsorption interface a, and the lower gas distributor 105 is used to evenly distribute the airflow flowing into the adsorption regeneration tank 1 from the desorption interface b.

[0062] A number of grille modules are stacked at intervals along the gas flow direction inside the cuboid shell to form a multi-layer structure. The number of grille modules is evenly arranged at intervals along the airflow direction, that is, the grille surface of each grille module is perpendicular to the airflow direction.

[0063] As an example, each grille module is supported in the cuboid shell by an ear-type support. There is no fixed connection between the grille module and the ear-type support (that is, the grille module can be directly placed on the ear-type support), which can prevent the outer shell 101 or the grille module from being damaged due to thermal expansion.

[0064] The grille module is composed of a number of grilles 106 spliced together. As Figure 8 and Figure 9 shown, the grille 106 includes a grid-shaped skeleton and a mesh surface. The skeleton is composed of a number of flat irons connected together. The mesh surface is installed on the mesh surface of the skeleton. The mesh surface is a wire mesh. In this embodiment, the diameter of the wire is preferably 1 mm, and the size of the wire mesh grid is preferably 30 mm to 80 mm.

[0065] In the grille module, one or more granular activated carbon modules 104 are placed on each grille 106; the granular activated carbon modules 104 on each layer form a granular activated carbon module group; as Figures 4 to 6 shown, each granular activated carbon module 104 includes granular activated carbon and a packaging module. The packaging module includes a frame 1041 and two filter meshes 1042. The frame 1041 is a grid-shaped structure, and the upper and lower end faces of the frame 1041 are open. The height range of the frame 1041 is preferably 50 mm to 150 mm, and the length and width of each grid are preferably 50 mm to 200 mm. The length, width and thickness of the frame 1041 (the thickness of the plate used to make the frame 1041) are set in combination with mechanical requirements. The two filter meshes 1042 are respectively installed on the two open end faces of the frame 1041.

[0066] In this embodiment, the mesh number of the filter screen 1042 is preferably 16 meshes, and the diameter of the filter screen 1042 (the diameter of the iron wire used to make the filter screen 1042) is preferably 1 mm to 3 mm. Each grid of the frame 1041 is filled with granular activated carbon. In this embodiment, the granular activated carbon is preferably columnar granular activated carbon or amorphous granular activated carbon with good adsorption performance and regeneration performance. In this embodiment, the particle size of the columnar granular activated carbon (this particle size is the equivalent particle size) is preferably 1.5 mm to 4 mm, and the particle size of the amorphous granular activated carbon (this particle size is the equivalent particle size) is preferably 1.5 mm to 5 mm. The ash on the granular activated carbon needs to be removed before the granular activated carbon is loaded into the encapsulation module to avoid the ash affecting the adsorption effect of the granular activated carbon. The open end of the encapsulation module of each granular activated carbon module 104 is perpendicular to the flow direction of the air flow. The distance between every two adjacent granular activated carbon modules 104 up and down is 30 mm to 80 mm.

[0067] The hatch 102 is installed on the cuboid shell or the frustum of a pyramid located above. The hatch 102 is used for the staff to enter and exit and for the setting of the granular activated carbon module 104.

[0068] The sealing ring is installed on the edge of the hatch 102, and the sealing ring is used to prevent the gas inside the outer shell 101 from flowing out.

[0069] Working principle:

[0070] The adsorption and regeneration box in this embodiment is used for the adsorption and desorption of volatile organic compounds (VOCs) in the waste gas.

[0071] In the granular activated carbon module 104, the granular activated carbon is evenly distributed in each grid, reducing the accumulation amount of the granular activated carbon and alleviating the disordered accumulation of the granular activated carbon, thereby reducing the pressure loss in the granular activated carbon. During adsorption, the waste gas can be in full contact with the granular activated carbon, thereby improving the adsorption performance. During desorption, the accumulation density of volatile organic compounds (VOCs) can be reduced, facilitating the desorbed gas to carry away the volatile organic compounds (VOCs), preventing local temperature rise in the granular activated carbon module 104 from causing a fire, and thus improving the desorption performance.

[0072] The gas distributor 105 can make the gas entering the adsorption and regeneration box 1 evenly distributed in the outer shell 101, so that the gas can be in full contact with all the granular activated carbon modules 104, further improving the adsorption performance and desorption performance of the adsorption and regeneration box 1.

[0073] Embodiment 2:

[0074] On the basis of Embodiment 1, this embodiment provides an adsorption and regeneration box loaded with granular activated carbon, and the adsorption and regeneration box device further includes: a seal 103.

[0075] The seal 103 is arranged between two adjacent granular activated carbon modules 104 in each layer, and between the granular activated carbon module 104 at the end and the inner wall surface of the cuboid shell of the outer shell 101.

[0076] The seal 103 is used to prevent air flow from flowing out of the gaps between the granular activated carbon modules 104 and the gaps between the granular activated carbon module 104 and the inner wall surface of the cuboid shell, thereby improving the adsorption performance and desorption performance of the adsorption and regeneration tank 1.

[0077] In this embodiment, the seal 103 is made of aluminosilicate fiber cotton.

[0078] Embodiment 3:

[0079] This embodiment provides an adsorption and regeneration tank loaded with granular activated carbon, based on the adsorption and regeneration tank in Embodiment 1.

[0080] In this embodiment, several lug supports in Embodiment 1 are replaced by several guide rails.

[0081] Each layer of grille module is spliced by several grilles 106 arranged in parallel. The grille 106 is slidably connected to the inner wall surface of the outer shell 101 through a guide rail. The guide rail is used for the arrangement and movement of the grille 106 with the granular activated carbon module 104 placed thereon.

[0082] Embodiment 4:

[0083] As Figure 10 shown, based on the adsorption and regeneration tank 1 in Embodiments 1 - 3, this embodiment provides an adsorption and regeneration system, including: an adsorption and regeneration tank 1 and a regeneration device 2;

[0084] The regeneration device 2 is used to generate desorption gas and treat the desorbed volatile organic compounds (VOCs). In this embodiment, the regeneration device 2 is preferably a CO furnace or an RTO furnace.

[0085] In the adsorption and regeneration tank 1, the adsorption interface a of the three-way joint 107 located above is connected to the waste gas pipe, and the adsorption interface b is directly connected to the atmosphere. The desorption interface a is connected to the inlet of the regeneration device 2 through a ventilation pipe, and the desorption interface b is connected to the outlet of the regeneration device 2 through a ventilation pipe.

[0086] Working principle:

[0087] The adsorption and regeneration system in this embodiment can have the working modes of online desorption or offline desorption of the honeycomb activated carbon desorption and regeneration system.

[0088] When the adsorption regeneration system performs adsorption, the air flow (waste gas) enters the adsorption regeneration tank 1 through the adsorption interface a above the adsorption regeneration tank 1. The waste gas entering the adsorption regeneration tank 1 passes through each layer of granular activated carbon module 104 in the adsorption regeneration tank 1 and then flows into the atmosphere through the adsorption interface b below the adsorption regeneration tank 1 to complete adsorption.

[0089] When the adsorption regeneration system performs desorption, the air flow (the high-temperature desorption gas generated by the regeneration device 2) enters the adsorption regeneration tank 1 through the desorption interface b below the adsorption regeneration tank 1. The desorption gas entering the adsorption regeneration tank 1 raises the temperature inside the adsorption regeneration tank 1, thereby reducing the adsorption force between the volatile organic compounds (VOCs) adsorbed by the granular activated carbon and the granular activated carbon. At the same time, the air flow formed by the desorption gas can carry away the volatile organic compounds (VOCs) on the surface of the granular activated carbon, causing the volatile organic compounds (VOCs) to detach from the surface of the granular activated carbon. The desorbed volatile organic compounds (VOCs) flow into the regeneration device 2 through the desorption interface a above the adsorption regeneration tank 1, and the volatile organic compounds (VOCs) are processed by the regeneration device 2 to complete desorption.

[0090] In summary, the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
