Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to an activated carbon fiber adsorption and desorption device. Background Art

[0002] Activated carbon fiber adsorption and desorption device is widely used in organic waste gas treatment; it can first adsorb and concentrate the organic waste gas, and then introduce the desorbed high-concentration organic waste gas into the subsequent purification treatment device to remove pollutants; the concentration multiple can reach 5-20 times, which effectively reduces the processing load of subsequent purification equipment.

[0003] The activated carbon fiber adsorption and desorption device in the prior art is internally loaded with a large number of activated carbon particles. During the desorption process of the activated carbon particles, hot steam needs to be introduced to desorb the pollutants adsorbed on the activated carbon. The activated carbon particles are generally accumulated in the inner cavity of the adsorption box. During desorption, the pollutants desorbed from the uppermost layer of activated carbon particles will flow along the top of the activated carbon to the bottom of the adsorption box and finally flow out from the bottom. The desorbed activated carbon particles will need to be desorbed again due to the re-flow of pollutants. This process takes a long time and the desorption efficiency is not high. Therefore, an activated carbon fiber adsorption and desorption device is proposed. Utility Model Content

[0004] The utility model aims to provide an activated carbon fiber adsorption and desorption device in order to solve the problem that the existing activated carbon fiber adsorption and desorption device has low desorption efficiency and takes a long time during desorption.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an activated carbon fiber adsorption and desorption device, comprising an adsorption box, the bottom input end of the adsorption box is connected to an air inlet pipe, the output end of the adsorption box is connected to an air outlet pipe, a plurality of desorption plates are installed on the inner wall of the adsorption box, the top of the desorption plate is used to place activated carbon, the plurality of desorption plates are equidistantly arranged in the vertical direction, the interior of the desorption plate is a cavity structure, a desorption mechanism is arranged on the desorption plate, the desorption mechanism is used to remove pollutants generated after desorption of multiple groups of activated carbon in layers, and the desorption mechanism includes a ventilation component and a decontamination component.

[0006] As a further solution of the utility model: the ventilation assembly includes a ventilation pipe, a ventilation convex block, and a ventilation groove;

[0007] The ventilation pipe is fixedly connected to the upper and lower ends of the inner cavity of the desorption plate, and a plurality of the ventilation pipes are equidistantly arranged. The ventilation groove is opened on the ventilation pipe and passes through the ventilation pipe. The ventilation protrusion is arranged at the top of the desorption plate, and the air inlet of the ventilation protrusion corresponds to the ventilation groove.

[0008] As a further solution of the utility model: the decontamination assembly includes a sewage collection hole and a sewage discharge pipe;

[0009] The sewage collecting holes are opened at the top of the desorption plate and directly pass through the inner cavity of the desorption plate. The sewage collecting holes are arranged in multiple groups and equidistantly. The sewage collecting holes are adjacent to the positions of the ventilation protrusions. The sewage discharge pipe is arranged at the center of one side of the desorption plate and extends to the outer wall of the adsorption box.

[0010] As a further solution of the utility model: the desorption plate is arranged in a "V" shape, and the plurality of sewage pipes are collected in a sewage collecting pipe, and the output end of the sewage collecting pipe is connected to a sewage collecting box.

[0011] As a further solution of the utility model: a steam pipe is connected to the other side of the adsorption box, the steam pipe runs through the inner cavity of the adsorption box, and the input end of the steam pipe is connected to a steam generator.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting a desorption mechanism, when using this arrangement for desorption after adsorption, hot steam is introduced into the adsorption box through the steam generator, and the hot steam flows through each layer of desorption plate through the ventilation groove to desorb the activated carbon placed on the desorption plate, and the pollutants on the activated carbon are desorbed into liquid, which flows from the sewage collecting hole to the inner cavity of the desorption plate. Due to the "V" shape of the desorption plate, the liquid pollutants flow from the inner cavity of the desorption plate to the sewage pipe and finally flow into the sewage collecting box to complete the desorption. This design ensures that the pollutants generated by the desorption of the activated carbon on each layer of the desorption plate are processed layer by layer, and the pollutants will not flow through the activated carbon that has been desorbed again, requiring secondary desorption, thereby effectively improving the efficiency of desorption.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 In the embodiment of the utility model, the activated carbon fiber adsorption and desorption device includes an adsorption box 2, the bottom input end of the adsorption box 2 is connected to the air inlet pipe 1, the output end of the adsorption box 2 is connected to the air outlet pipe 3, and the inner wall of the adsorption box 2 is installed with multiple desorption plates 6. The top of the desorption plate 6 is used to place activated carbon. The multiple desorption plates 6 are equidistantly arranged in the vertical direction. The interior of the desorption plate 6 is a cavity structure. A desorption mechanism 7 is arranged on the desorption plate 6. The desorption mechanism 7 is used to remove pollutants generated after desorption of multiple groups of activated carbon in layers. The desorption mechanism 7 includes a ventilation component and a decontamination component.

[0022] In this embodiment: when the present arrangement is used to desorb the adsorption box 2 after adsorption, the pipe openings of the air inlet pipe 1 and the air outlet pipe 3 are closed, and then hot steam is introduced into the adsorption box 2 through an external device. The hot steam introduced into the adsorption box 2 flows through each layer of the desorption plate 6 through the ventilation component, so that the pollutants adsorbed on the activated carbon are desorbed, and the desorbed pollutants flow into the inner cavity of the desorption plate 6 through the decontamination component, and finally flow out from the inner cavity of the desorption plate 6. This design enables the pollutants generated by the desorption of the activated carbon on each layer of the desorption plate 6 to be processed layer by layer, and the pollutants will not flow through the activated carbon that has been desorbed again, requiring secondary desorption, thereby effectively improving the efficiency of desorption.

[0023] Please refer to Figures 3 to 5 , the ventilation assembly includes a ventilation pipe 701, a ventilation protrusion 702, and a ventilation groove 704;

[0024] The ventilation pipe 701 is fixedly connected to the upper and lower ends of the inner cavity of the desorption plate 6, and multiple ventilation pipes 701 are arranged at equal distances. The ventilation groove 704 is opened on the ventilation pipe 701 and penetrates the ventilation pipe 701. The ventilation protrusion 702 is arranged at the top of the desorption plate 6, and the air inlet of the ventilation protrusion 702 corresponds to the ventilation groove 704.

[0025] In this embodiment: hot steam is introduced into the adsorption box 2 through an external device, the hot steam flows into the ventilation groove 704 through the ventilation protrusion 702, and finally flows out from the ventilation groove 704. Due to the arrangement of multiple ventilation grooves 704, the hot steam can flow between the multiple desorption plates 6 in the adsorption box 2, react with the activated carbon placed on the desorption plate 6 to desorb the pollutants, and the design of the ventilation protrusion 702 allows only gases to circulate through the ventilation groove 704, and the desorbed pollutants of the liquid cannot flow through the ventilation protrusion 702, so that the pollutants generated on each layer of the desorption plate 6 will not flow to the next layer of the desorption plate 6.

[0026] Please refer to Figures 2 to 4 , the decontamination assembly includes a dirt collecting hole 703 and a drain pipe 8;

[0027] The sewage collecting holes 703 are opened at the top of the desorption plate 6 and directly pass through the inner cavity of the desorption plate 6. The sewage collecting holes 703 are arranged in multiple groups and equidistantly. The sewage collecting holes 703 are adjacent to the positions of the ventilation protrusions 702. The sewage discharge pipe 8 is arranged at the center of one side of the desorption plate 6 and extends to the outer wall of the adsorption box 2.

[0028] In this embodiment: the hot steam introduced into the adsorption box 2 causes the activated carbon on the desorption plate 6 to desorb pollutants, which flow through the pollution collecting hole 703 to the inner cavity of the desorption plate 6, gather in the inner cavity of the desorption plate 6, and are finally discharged from the sewage pipe 8, flowing out of the inner cavity of the desorption plate 6 and the adsorption box 2, completing the desorption. Each layer of the desorption plate 6 is independently desorbed, and no secondary desorption is required, so that the desorption efficiency is improved.

[0029] Please refer to Figures 3 to 5 The desorption plate 6 is arranged in a "V" shape, and a plurality of sewage pipes 8 are collected in a sewage collecting pipe 9, and the output end of the sewage collecting pipe 9 is connected to a sewage collecting box 5.

[0030] In this embodiment, the "V"-shaped desorption plate 6 makes it easier for the pollutants generated at both ends of the inner cavity of the desorption plate 6 to be concentrated at the center and discharged from the sewage pipe 8. The pollutants discharged from multiple sewage pipes 8 are collected in the sewage collection pipe 9 and flow into the sewage collecting box 5. The pollutants in the sewage collecting box 5 can then be centrally treated.

[0031] Please refer to Figure 1 The other side of the adsorption box 2 is connected to a steam pipe 10 , the steam pipe 10 runs through the inner cavity of the adsorption box 2 , and the input end of the steam pipe 10 is connected to the steam generator 4 .

[0032] In this embodiment, the steam generator 4 is used to generate a continuous supply of hot steam which is passed into the adsorption box 2 through the steam pipe 10 to desorb the activated carbon.

[0033] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
