By adopting the scheme, in specific practice, the exhaust gas can be selectively and independently introduced into the first adsorption channel 2a or the second adsorption channel 2b, or the exhaust gas can be selectively introduced into the first adsorption channel 2a and the second adsorption channel 2b simultaneously, so that more operation modes can be provided, and the situation that the concentration of the organic matters in the exhaust gas in the upstream production equipment is complicated and variable can be better adapted.

Moreover, because the first adsorption channel 2a and the second adsorption channel 2b can be arranged at an included angle, when a conveying air duct communicated with the two adsorption channels is constructed, the conveying air duct can be distributed on different sides of the adsorption body 2, which is more beneficial to the arrangement of the air duct. In addition, the arrangement of a plurality of flow directions can effectively reduce the adsorption dead angle caused by the factors such as uneven air flow distribution, and the like, so that the adsorption body 2 can be more fully utilized, and the adsorption efficiency can be further improved.

It should be noted that, the embodiment of the present invention does not limit the included angle between the extending direction of the first adsorption channel 2a and the extending direction of the second adsorption channel 2b, and in the specific implementation, those skilled in the art can set the included angle according to actual needs. In the embodiment of the drawings, as shown in fig. 2 and 4, the extending direction of the first adsorption passage 2a and the extending direction of the second adsorption passage 2b may be at an angle of substantially 90 degrees.

In the solution described above, the adsorbent 2 comprises only adsorption channels having two directions of extension, respectively a first adsorption channel 2a and a second adsorption channel 2 b. In fact, the adsorbent body 2 may also comprise adsorption channels with more extension directions, which may be used in practical applications, and the specific requirements are determined by combining the practical use requirements.

The embodiment of the utility model provides a do not still inject the material of adsorbent 2, in the concrete practice, technical personnel in the field can design according to actual need, as long as can satisfy carry out absorptive technical purpose to the organic matter can.

At least a part of the adsorbent 2 may be made of an organic adsorbent, and the kind of the organic adsorbent may be various. For example, the organic material adsorbent may be a fibrous material having an adsorption function, such as activated carbon fiber; or, the organic matter adsorbing material can also adopt inorganic fibers such as ceramic fibers, glass fibers and the like as loads and is combined with activated carbon, molecular sieves or other organic matter adsorbing materials to form a whole; alternatively, the organic adsorbent may be a ceramic material containing activated carbon, molecular sieves, or other organic adsorbents.

In addition, the embodiment of the present invention also does not limit the structural form of the adsorbent 2, and the number of the adsorption channels, the cross-sectional shape (the cross-section perpendicular to the extending direction), the flow area, etc. in the specific practice, those skilled in the art can design according to the actual need as long as the actual use requirement can be satisfied.

In a specific scheme, with reference to fig. 2 to 4, the adsorbent 2 may include a plurality of substrates 211 arranged at intervals, an adsorption space may be formed between two adjacent substrates 211, and a flow divider 212 may be arranged between two adjacent substrates 211, so as to divide the first adsorption channel 2a and the second adsorption channel 2b in the adsorption space. The flow divider 212 and the substrate 211 may both use the organic adsorbent described above, or only one of them may use the organic adsorbent described above.

The shunt 212 and the substrate 211 may be manufactured separately and then assembled. In this embodiment, the connection between the shunt member 212 and the substrate 211 may be various, as long as the reliable connection between the shunt member and the substrate can be ensured. For example, the shunt member 212 and the substrate 211 may be fixed by bonding, locking screws, welding, clamping, and the like. When the adhesive fixing is adopted, the kind of the adhesive may not be limited.

In fact, the shunt member 212 and the base plate 211 may be a one-piece structure integrally formed. For example, the absorbent body 2 formed by combining the shunt member 212 and the substrate 211 may be directly obtained by 3D printing technology, so that the acquisition of the absorbent body 2 may be relatively simple.

It will be appreciated that the structural form and arrangement of the flow divider 212 directly determine the cross-sectional shapes of the first adsorption passage 2a and the second adsorption passage 2 b.

In the embodiment of fig. 2 and 3, the flow divider 212 may be embodied as a corrugated board, in which case the cross-sectional shape of the first adsorption channel 2 a/second adsorption channel 2b formed is substantially triangular. Alternatively, the flow divider 212 may be a plate that forms an included angle with the substrate 211, and at this time, the cross-sectional shape of the first adsorption channel 2 a/the second adsorption channel 2b may be a triangle, a rectangle, a parallelogram, a trapezoid, a rhombus, or the like, according to the arrangement of the flow divider 212.

In the embodiment of fig. 4, the flow divider 212 may be embodied as a tube. At this time, the first adsorption passage 2 a/the second adsorption passage 2b may include a space between the pipe and the substrate 211, a space between adjacent two pipes, and the like, in addition to the in-pipe passage of the pipe; it should be noted that if the space between the pipe and the substrate 211 and the space between two adjacent pipes are already filled with glue or other materials, the first adsorption channel 2 a/the second adsorption channel 2b may not include these spaces. The specific shape of the channel in the pipe is related to the shape of the pipe fitting; in the embodiment of fig. 4, the pipe is a circular pipe, and accordingly, the channel in the pipe is a circular channel.

It is to be understood that the above description is only illustrative of the possible cross-sectional shapes of the first adsorption channel 2 a/the second adsorption channel 2b, but this is not intended as a limitation to the scope of the present invention, and the cross-sectional shapes of the first adsorption channel 2 a/the second adsorption channel 2b can be designed to be other under the condition of satisfying the function, as long as the conduction of the first adsorption channel 2 a/the second adsorption channel 2b to the exhaust gas is not affected.

The first adsorption passage 2a and the second adsorption passage 2b may be located in different adsorption spaces, and thus, the first adsorption passage 2a and the second adsorption passage 2b may be located in different layers, which makes it easier to feed the exhaust gas into the first adsorption passage 2a and the second adsorption passage 2 b. In this embodiment, the adsorption space in which the first adsorption channel 2a is disposed and the adsorption space in which the second adsorption channel 2b is disposed may be adjacent to each other, and this scheme may be shown in fig. 2 to 4, that is, one of the adjacent adsorption spaces may be formed with the first adsorption channel 2a, and the other may be formed with the second adsorption channel 2 b; alternatively, the first adsorption channel 2 a/the second adsorption channel 2b may be disposed in several adjacent layers.

For convenience of description, the extending direction of the first adsorption channel 2a may be referred to as a first direction, and the extending direction of the second adsorption channel 2b may be referred to as a second direction.

While the off-gas flows within the adsorbent 2, it may directly flow from one end to the other end of the first adsorption passage 2a to penetrate the entire adsorbent 2 in the first direction; and, may directly flow from one end to the other end of the second adsorption passage 2b to penetrate the entire adsorbent 2 in the second direction.

Alternatively, the absorbent member 2 may be divided into a plurality of first sections 21 in the first direction. The division mode can be based on the split design of the adsorbent 2 in the first direction, in this case, the adsorbent 2 is formed by combining a plurality of separately prepared first subsections 21, the size of each first subsection 21 in the first direction can be relatively small, and the manufacturing, transportation and installation can be convenient; in this embodiment, the first sections 21 may be in close contact or may be in clearance fit in the first direction, but it is necessary to ensure that the first adsorption passages 2a of the first sections 21 communicate with each other. Or, the absorbent 2 may still be of an integrated structure in the first direction, and in this case, the absorbent 2 needs to be divided in the first direction by a worker according to actual situations.

Further, a first switching duct 4a may be further included, and the second adsorption passages 2b of the first sections 21 may be communicated with each other through the first switching duct 4 a. For the sake of description, the first adsorption channel 2a may be referred to as a first flow path, and the path formed by the combination of each second adsorption channel 2b and the first transfer duct 4a may be referred to as a second flow path.

With the above configuration, the length of the second flow path is substantially equal to the sum of the sizes of the second adsorption passages 2b of the first divisions 21 and the size of the first transfer air duct 4a in the air flow direction, and the length of the second flow path is significantly increased, so that the flow resistance of the exhaust gas in the second flow path can be increased.

Further, it is also possible to set the flow resistance of the first flow path to be smaller than that of the second flow path, so that the amount of exhaust gas entering the second flow path can be smaller than that of the first flow path.

In the embodiment of the present invention, the number of the first parts 21 is not limited, and in practical applications, those skilled in the art can design the parts according to actual needs as long as the requirements of use can be met. In the embodiment shown in the drawings, there may be three first division portions 21, and there may be four or more first division portions. Since one first transfer duct 4a can communicate with the second adsorption passages 2b of the two first divisions 21, the number of first transfer ducts 4a can be one less than that of the first divisions 21.

For convenience of description, each first section 21 may be named as follows from right to left, taking fig. 1 as a perspective view: a first division, a second division and a third division. The first switching duct 4a may be a second adsorption duct 2b connecting two adjacent first subsections 21, that is, the first subsection and the second subsection are connected through the first switching duct 4a, and the second subsection and the third subsection are connected through the first switching duct 4 a; at this time, the first switching duct 4a does not shield the inlet and outlet of the second flow path, and can facilitate air intake and air discharge. Alternatively, it is also possible to use other connection methods for the first transition duct 4a, for example, connecting the first branch and the third branch via the first transition duct 4a, and connecting the first branch/the third branch via the first transition duct 4a and the second branch.

The forming manner of the first switching duct 4a is not limited, and in specific practice, a person skilled in the art may set the first switching duct according to actual needs as long as the requirements of use can be met. In some embodiments, a tube may be provided, and two ends of the tube may be respectively connected to the two first branches 21, and an inner cavity of the tube may form the first transition duct 4 a. In other embodiments, a cover 4 may be included, and the cover 4 may be covered on one side of two adjacent first subsections in the extending direction of the second adsorption passage 2b to form a first transfer passage 4a by enclosing two adjacent first subsections 21; this embodiment can be seen in fig. 1, which is relatively simple in construction and provides a first switching duct 4a of the same volume, with less intrusion into the interior of the housing 1.

When the number of the first switching ducts 4a is two or more, only a part of the first switching ducts 4a may be provided with the heater 3. Of course, the heaters 3 may be provided in all the first transition ducts 4 a. The type of the heater 3 is not limited herein.

The heater 3 is used for heating all or part of the exhaust gas entering the second adsorption channel 2b, and further can heat the adsorbent 3 to realize desorption of organic matters. As described above, by reducing the amount of exhaust gas entering the second flow path, the amount of exhaust gas to be heated by the heater 3 can be reduced, so that energy consumption can be reduced and cost can be saved.

In specific practice, the heating power and the turn-on number of the heater 3 can be controlled to avoid the situation that the concentration of organic matters in the exhaust gas received by the downstream exhaust gas treatment equipment is suddenly increased due to too much desorption at the initial start-up stage of the heater 3. In other words, in actual operation, the heating power and the number of the heaters 3 can be controlled to adjust the desorption efficiency, so that the concentration curve of the organic matters in the exhaust gas received by the downstream exhaust gas treatment device can be substantially as shown in fig. 2, so as to treat the organic matters in the exhaust gas.

In the scheme, the adsorbent 2 is divided in the extending direction of the first adsorption channel 2a to divide the adsorbent 2 into a plurality of first sub-parts 2a, and the length of the second flow path is prolonged by matching with the first switching air channel 4 a; it is equivalent to the exhaust gas not flowing through all the second adsorption passages 2b at a time directly, but turning through the first switching duct 2b to form a serpentine second flow path. In fact, this solution is also applicable to the first adsorption passage 2a, that is, it is also possible to divide the adsorbent body 2 into a plurality of second subsections in the extending direction of the second adsorption passage 2b, and then to communicate the first adsorption passages 2a of the two second subsections through the second transfer duct.

The utility model provides a device, including the adsorption element that aforementioned each embodiment relates, because aforementioned adsorption element has possessed above technological effect, so, the device that has this adsorption element also should possess similar technological effect, and the retrench is not repeated here.

Here, the embodiment of the present invention is not limited to the kind of the device including the adsorption member, and in a specific practice, a person skilled in the art may select the adsorption member according to actual needs. For example, the device may be an exhaust gas concentration adjusting device for converting an exhaust gas having a large fluctuation in the concentration of organic substances discharged from an upstream production facility into an exhaust gas having a relatively stable concentration of organic substances; in specific practice, the adsorbent 2 may be started to adsorb the organic matters in the exhaust gas when the concentration of the organic matters is high so as to reduce the concentration of the organic matters, and the heater 3 may be started when the concentration of the exhaust gas is low so as to desorb the organic matters adsorbed by the adsorbent 2 so as to increase the concentration of the organic matters; in this way, the downstream exhaust gas treatment device can be relatively simple to model.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
