Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a modular adjustable activated carbon box. Background Technology

[0002] Activated carbon absorption is a method of air purification widely used in industrial waste gas treatment and air purification. Its core principle is to utilize the adsorption capacity of activated carbon to remove harmful substances from gases, such as volatile organic compounds (VOCs), odors, and acidic gases. The activated carbon housing is a key component in air purification equipment, used to adsorb harmful gases and odors from the air. Traditional square activated carbon housings are usually fixed structures; their size and shape are determined during manufacturing, making it impossible to adjust the size and shape according to different application scenarios and purification needs. Furthermore, when treating large volumes of exhaust gas, the housing needs to be enlarged to accommodate the increased filtration area, which in turn increases the weight of the activated carbon and increases manufacturing complexity. Simultaneously, the square housing occupies a large space during transportation and storage, increasing logistics costs. Utility Model Content

[0003] To address the above shortcomings, the purpose of this utility model is to provide a modular adjustable activated carbon box. This modular adjustable activated carbon box has a small footprint, is flexible in installation, can be adjusted according to site conditions, and can also be adjusted according to the amount of exhaust gas to be treated. It is easy to manufacture and has low logistics costs.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A modular adjustable activated carbon housing includes a housing with multiple filter units installed vertically and vertically within it. A gas inlet is located on the lower side of each filter unit on the housing, and each gas inlet is connected to a tail gas distribution pipe via a distribution valve. The tail gas distribution pipe has an air inlet. A gas outlet is located on the upper side of each filter unit on the housing, and each gas outlet is connected to a tail gas collection pipe via a collection valve. The tail gas collection pipe has an air outlet.

[0006] The exhaust gas distribution pipe is provided with a distribution branch pipe corresponding to each of the gas inlets, and the distribution valve is sealed between the distribution branch pipe and the gas inlet; the diameter of the connected distribution branch pipe and the gas inlet is the same, while the diameter of each gas inlet is different.

[0007] The exhaust gas collection pipe is equipped with a collection branch pipe corresponding to each gas outlet, and the collection valve is sealed between the collection branch pipe and the gas outlet; the diameter of the connected collection branch pipe and the gas outlet is the same, while the diameter of each gas outlet is different.

[0008] The filtration unit includes a support pipe connected to the housing at both ends, a support frame on the support pipe, a grid plate on the support frame, a filter screen on the grid plate, and activated carbon covering the filter screen.

[0009] The spacing between each filter unit is 1700-1900 mm, and the thickness of the activated carbon is 250-350 mm.

[0010] The filter unit is provided with a spray device on its lower side. The spray device includes a spray pipe fixed on the lower side of the support pipe, and multiple spray heads are installed on the lower side of the spray pipe.

[0011] The housing located on the upper and lower sides of each filter unit is provided with an inspection hole, and a temperature sensor is installed inside the inspection hole.

[0012] The bottom of the box is equipped with a drain port.

[0013] The air inlet is connected to an explosion-proof valve.

[0014] The box body is a cylindrical structure with sealed top and bottom, and the box body is made of fiberglass.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] The modular adjustable activated carbon box of this utility model includes a box body, in which multiple filter units are installed vertically at intervals; a gas inlet is provided on the box body located below each odd number of filter units, and each gas inlet is connected to a tail gas distribution pipe through a distribution valve, and the tail gas distribution pipe is provided with an air inlet; a gas outlet is provided on the box body located above each odd number of filter units, and each gas outlet is connected to a tail gas collection pipe through a collection valve, and the tail gas collection pipe is provided with an air outlet. The housing of this invention can be designed in a circular shape, occupying a small area. The exhaust gas distribution pipe and exhaust gas collection pipe are designed separately from the housing, allowing for flexible installation based on available space. The design incorporates multiple filter units, gas inlets, and outlets, enabling adjustment of the exhaust gas volume via valves. More valves are opened for larger volumes, and fewer for smaller volumes, providing flexible adjustment without altering the housing's dimensions or structure. Furthermore, the multiple filter units are distributed evenly with the activated carbon, and the number of filter units can be determined based on overall needs. Increasing or decreasing the number of filter units only requires adjusting the housing's height, without increasing its floor space. This significantly reduces the difficulty of manufacturing the housing, as well as production and transportation costs.

[0017] In summary, the modular adjustable activated carbon box of this utility model solves the technical problems of large footprint, poor installation and tail gas treatment capacity adjustment in the prior art. The modular adjustable activated carbon box of this utility model has a small footprint, flexible installation, can be adjusted according to the site conditions, and can be adjusted according to the tail gas volume to be treated. It is easy to manufacture and has low logistics costs. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The directions mentioned in this manual are based on the directions shown in the attached diagram and represent only relative positional relationships, not absolute positional relationships.

[0024] like Figure 1As shown, a modular adjustable activated carbon housing includes a housing 10. Multiple filter units 20 are installed vertically and vertically within the housing 10. A gas inlet is located on the lower side of each filter unit 20 within the housing 10. Each gas inlet is connected to a tail gas distribution pipe 40 via a distribution valve. The tail gas distribution pipe 40 has an inlet 42. A gas outlet is located on the upper side of each filter unit 20 within the housing 10. Each gas outlet is connected to a tail gas collection pipe 50 via a collection valve. The tail gas collection pipe 50 has an outlet 52. In use, the tail gas to be treated enters the tail gas distribution pipe 40 through the inlet 42, then enters the housing 10 through the gas inlet, is purified and filtered by the filter units 20, and then enters the tail gas collection pipe 50 through the gas outlet. Finally, it is discharged through the outlet 52. This utility model features a separate design for the exhaust gas distribution pipe 40 and the exhaust gas collection pipe 50 from the housing 10. During on-site installation, the orientation of the air inlet 42 and the air outlet 52 can be adjusted according to the available space (e.g., ...). Figure 2 and Figure 3 As shown in the figure, the installation is very flexible, and the opening and closing of each distribution valve and the main valve can be adjusted according to the amount of exhaust gas to be treated, making the adjustment more convenient and flexible.

[0025] like Figure 1 As shown, in this embodiment, the preferred housing 10 is a circular cylindrical structure, with a bottom plate sealed to the bottom and a top cover sealed to the top, i.e., the housing 10 is a cylindrical structure sealed from top to bottom. Further in this embodiment, the housing 10 is made of fiberglass. Fiberglass housings are easy to process because the cylindrical fiberglass housing is formed by winding it in concentric circles, so the height of the housing can be freely processed as needed without being limited by the size of the raw materials. Furthermore, fiberglass housings have strong corrosion resistance, effectively increasing the service life of the activated carbon housing.

[0026] like Figure 1 As shown, the modular adjustable activated carbon housing of this utility model can determine the height of the housing 10 and the number of filter units 20 installed inside it according to the amount of exhaust gas to be treated. The structure of the activated carbon housing is described in detail below using three filter units 20 as an example. In this embodiment, the spacing between the three filter units 20 is preferably 1700-1900mm, and further, the three filter units 20 are installed inside the housing 10 with a vertical spacing of about 1800mm.

[0027] like Figure 1As shown, the filter unit 20 includes multiple support pipes 24 connected to the housing 10 at both ends. Each support pipe 24 is located on the same plane, and each support pipe 24 is provided with a support frame 26. The support frame 26 is a circular structure adapted to the cross-section of the housing 10, and the support frame 26 is composed of multiple strips connected together horizontally and vertically. That is, the support frame 26 is a cross-shaped support frame or a grid-shaped support frame. The support frame 26 is provided with a grid plate 28. The shape and size of the grid plate 28 are consistent with the shape and size of the support frame 26. The grid plate 28 is provided with a filter screen. The shape and size of the filter screen are consistent with the shape and size of the grid plate 28 (not shown in the figure because the thickness of the filter screen is too small). The filter screen is covered with activated carbon 22. In order to ensure the filtration effect, the activated carbon 22 covers the entire filter screen. In this embodiment, the preferred thickness of the activated carbon 22 is 250-350 mm, and a further preferred thickness of 300 mm.

[0028] like Figure 1 As shown, a spray device is installed on the lower side of the filter unit 20. This spray device can be installed only below the uppermost filter unit 20, or one set can be installed below each filter unit 20. The spray device includes a spray pipe 30 fixed to the lower side of the support pipe 24, and multiple spray heads 32 are installed on the lower side of the spray pipe 30. When the composition of the exhaust gas is uneven, the absorption by activated carbon will generate a certain amount of adsorption heat, thus causing spontaneous combustion or flash explosion. The spray device can be activated when the temperature inside the housing 10 is too high to cool the housing 10, effectively preventing spontaneous combustion or flash explosion and improving the safety of equipment operation.

[0029] like Figure 1As shown, a gas inlet is provided on the housing 10 below the odd-numbered filter unit 20. In this embodiment, there are three filter units 20. Therefore, there is a gas inlet on the housing 10 below the bottommost and topmost filter units 20, respectively referred to as the first gas inlet 16 and the second gas inlet 17. The tail gas distribution pipe 40 is provided with a first distribution branch pipe 44 and a second distribution branch pipe 45 corresponding to the positions of the first gas inlet 16 and the second gas inlet 17. The first gas inlet 16 and the first distribution branch pipe 44 are sealed together by a first distribution valve 60, and the second gas inlet 17 and the second distribution branch pipe 45 are sealed together by a second distribution valve 61. In this embodiment, the diameters of the first gas inlet 16 and the first distribution branch pipe 44 are equal, both being DN600; the diameters of the second gas inlet 17 and the second distribution branch pipe 45 are equal, both being DN800. That is, the diameters of the first gas inlet 16 and the second gas inlet 17 are not equal. The reason for this difference is that the first gas inlet 16 is located between the bottommost filter unit 20 and the bottom of the housing 10, and the exhaust gas entering from it can only flow upwards. The second gas inlet 17, on the other hand, is located between the two filter units 20, and the exhaust gas entering from it can flow both upwards and downwards. Therefore, designing the diameter of the second gas inlet 17 to be larger than that of the first gas inlet 16 can increase the intake of exhaust gas while ensuring the filtration effect.

[0030] like Figure 1 As shown, the housing 10 has a gas outlet located above the odd-numbered filter unit 20. In this embodiment, there is a gas outlet on the housing 10 above the bottommost and topmost filter units 20, respectively denoted as the first gas outlet 18 and the second gas outlet 19. The exhaust gas collection pipe 50 has a first collection branch pipe 54 and a second collection branch pipe 55 corresponding to the positions of the first gas outlet 18 and the second gas outlet 19. The first gas outlet 18 and the first collection branch pipe 54 are sealed together by a first collection valve 62, and the second gas outlet 19 and the second collection branch pipe 55 are sealed together by a second collection valve 63. In this embodiment, the diameters of the first gas outlet 18 and the first collection branch pipe 54 are equal, both DN800; the diameters of the second gas outlet 19 and the second collection branch pipe 55 are equal, both DN600. That is, the diameters of the first gas outlet 18 and the second gas outlet 19 are unequal. The reason for the unequal diameters is the same as the reason for the unequal diameters of the two gas inlets, so it will not be described in detail here.

[0031] like Figure 1As shown, the three filter units 20 divide the inner cavity of the overall housing 10 into four airflow chambers. For ease of description, these four airflow chambers are named, from bottom to top, the first airflow chamber 70, the second airflow chamber 72, the third airflow chamber 74, and the fourth airflow chamber 76. During operation, the opening of the first distribution valve 60 or the second distribution valve 61, or both distribution valves simultaneously, can be determined based on the volume of exhaust gas to be treated. The opening and closing of the corresponding first collection valve 62 and second collection valve 63 are also determined based on the exhaust gas volume. The exhaust gas to be treated enters the exhaust gas distribution pipe 40 through the inlet 42, and is then distributed by the opening and closing of the first distribution valve 60 and the second distribution valve 61: when the first distribution valve 60 is open, the gas enters the first airflow chamber 70 through the first gas inlet 16, flows upward, is filtered by the bottom filter unit 20, enters the second airflow chamber 72, and then enters the exhaust gas collection pipe 50 from the first gas outlet 18, and is discharged from the outlet 52. When the second distribution valve 61 is opened, the gas enters the third airflow chamber 74 through the second gas inlet 17. Part of the gas entering the third airflow chamber 74 flows upward and is filtered by the uppermost filter unit 20 before entering the fourth airflow chamber 76, and then enters the exhaust gas collection pipe 50 from the second gas outlet 19; the other part flows downward and is filtered by the middle filter unit 20 before entering the second airflow chamber 72, and then enters the exhaust gas collection pipe 50 from the first gas outlet 18, and finally is discharged from the outlet 52.

[0032] like Figure 1 As shown, inspection holes 12 are provided on the upper and lower sides of the housing 10 of the filter unit 20. That is, inspection holes 12 are provided on the housing 10 corresponding to the first airflow chamber 70, the second airflow chamber 72, the third airflow chamber 74, and the fourth airflow chamber 76. The inspection holes 12 can be used for workers to enter and exit to perform equipment maintenance, and can also be connected to the hopper for adding activated carbon 22. In this embodiment, it is preferable that each housing 10 corresponding to each airflow chamber is provided with three inspection holes 12, and the three inspection holes 12 are equally spaced around the circumference. The design of providing three inspection holes 12 for each airflow chamber facilitates maintenance. Even if the installation space of the housing 10 is small, and one or two inspection holes 12 are blocked, personnel can still enter and exit or add activated carbon through the other unblocked inspection hole 12. This makes the installation of the activated carbon housing of this utility model not limited by space, further improving its installation flexibility. Temperature sensors (not shown in the figure) are installed on the inside of each inspection hole 12. The temperature sensors can detect the temperature inside the box 10 at any time. When an abnormal temperature is detected, the air inlet 42 and the air outlet 52 can be closed in time, and the spray device can be activated to prevent the accident from happening immediately.

[0033] like Figure 1As shown, the bottom of the box 10 is provided with a drain port 14. When condensation occurs inside the box 10, the dew that drips to the bottom of the box 10 can be discharged from the box 10 through the drain port 14.

[0034] like Figure 1 As shown, an intake valve (not shown in the figure) is installed between the intake port 42 and the exhaust gas source pipe. In this embodiment, the intake valve is preferably an explosion-proof valve. When the explosion-proof valve detects abnormal exhaust gas pressure, it can automatically close the valve to prevent abnormal gas from entering the housing 10, thereby protecting the equipment and preventing accidents.

[0035] In summary, the modular adjustable activated carbon box of this utility model has a small footprint, is flexible in installation, can be adjusted according to the site conditions, and can be adjusted according to the amount of exhaust gas to be treated. It is easy to manufacture and has low logistics costs.

[0036] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
