Description

Adsorption treatment device

The present invention relates to an adsorption treatment device.

When VOC-containing factory exhaust gas is treated by adsorption and concentration, the exhaust gas contains gaseous substances that reduce adsorption performance in addition to VOC. The adsorbent whose adsorption performance is reduced must be replaced.

The adsorption body of the disc-type adsorption treatment device is specially formed in one piece, so the manufacturing cost is relatively high. Furthermore, when replacing the adsorbent body, the entire adsorbent body must be replaced, and the replacement operation is labor-intensive.

On the other hand, the plurality of adsorbents included in the cylinder-type adsorption treatment device each have a fixed shape, so the manufacturing cost can be reduced. When the adsorbent body is replaced, it can be partially replaced, so the replacement operation can be performed more easily.

Factors other than gaseous substances may also reduce adsorption performance. Examples of such factors include water vapor and dust. When water vapor and dust exist in the fluid to be processed, they will cause clogging of the adsorbent material.

In the disk-type adsorption treatment device, the sealing member that separates the adsorption section and the desorption section causes the adsorption body to rotate in a state of direct contact with the adsorption body. Therefore, water vapor and dust contained in the fluid to be processed may be caused to adhere to the adsorbent through the sealing member, thereby promoting clogging of the adsorbent.

On the other hand, in the cylinder-type adsorption treatment device, the sealing member that separates the adsorption section and the desorption section does not come into direct contact with the adsorbent, so moisture and dust do not contribute to clogging of the adsorbent.

As mentioned above, when considering the adsorption performance, it can be said that a cylinder-type adsorption treatment device is more suitable than a dish-type adsorption treatment device when processing a fluid to be processed containing substances that may affect the adsorbent.

This type of cylinder-type adsorption treatment device is disclosed in International Patent Publication No. 2017/006785 (Patent Document 1). [Known technical documents] [Patent Document]

The distance between the upright sealing materials 431 is preferably smaller than the width of the contact surface 22 on the outside of the separator 20 . This is because even if one of the sealing materials 431 fails, the airtightness can be ensured by the other sealing material 431 . The number of sealing members 430 provided in the inner sealing body 41 can be appropriately selected according to the specifications required for the adsorption treatment device 100 .

In the sealing body 40 having the above structure, the plurality of sealing members 430 can slide and contact the partition 20 when the cylindrical rotor 90 rotates to separate the adsorption area R2 and the desorption area R1.

Attached is area R1.

The fluid introduced into the adsorption region R2 is a fluid to be processed such as exhaust gas. The fluid to be processed contains an organic solvent as a substance to be processed. In the adsorption area R2, the fluid to be processed is purified.

During purification, first, the exhaust gas is introduced into the adsorption region R2 of the cylindrical rotor 90 from the outer circumferential side to the inner circumferential side of the cylindrical rotor 90 . When the exhaust gas introduced into the adsorption area R2 passes through the cylindrical rotor 90 in the radial direction, the organic solvent is adsorbed and removed by the plurality of adsorption bodies 30 located in the adsorption area R2, and is purified.

The clean air that has flowed into the central space 90 a of the cylindrical rotor 90 passes through the central space 90 a of the cylindrical rotor located around the inner peripheral flow path forming member 4 and flows out from the opening 11 a of the first disk 11 . The clean air flowing out from the opening 11 a is discharged to the outside of the processing chamber 1 through the first flow path forming member 2 .

The fluid introduced into the desorption region R1 is a heating fluid such as heated air. In the desorption region R1, the organic solvent adsorbed by the adsorbent 30 is desorbed, thereby regenerating the adsorbent 30 and generating a concentrated fluid with a higher concentration of organic solvent.

In order to desorb the organic solvent, heated air is introduced from the other end side of the inner peripheral flow path forming member 4 . The heated air introduced from the other end side of the inner peripheral flow path forming member 4 passes through the inside of the inner peripheral side flow path forming member 4 through the opening 11 a of the first disk 11 , and passes through the inner peripheral side flow path forming member 4 . One end side of 4 is introduced into the desorption region R1.

When the heated air introduced into the desorption area R1 passes through the cylindrical rotor 90 from the inner circumferential side to the outer circumferential side, the organic matter adsorbed by the plurality of adsorbents 30 located in the desorption area R1 is heated. Solvent desorption. The heated air containing the organic solvent is discharged from the desorption region R1 to the outer peripheral flow path forming member 5 as a concentrated fluid. The concentrated fluid discharged from the outer peripheral side flow path forming member 5 is introduced into a post-processing device for post-processing such as recovery or combustion.

At this time, the plurality of sealing members 430 provided in the sealing body 40 are intended to separate the adsorption area R2 and the desorption area R1. When the cylindrical rotor 90 rotates, they can slide and contact the partition 20, so as to separate the adsorption area R2 and the desorption area R1. This method is provided in the inner peripheral side flow path forming member 4 which is a desorption inlet channel member, and the outer peripheral side flow path forming member 5 which is a desorption outlet channel member. Therefore, the adsorption region R2 and the desorption region R1 are separated in an airtight manner by the sealing member 430 among the plurality of sealing members 430 that is in contact and sliding with the separator 20 .

Since the sealing body 40 is composed of a plurality of sealing members 430 in one piece, the sealing body 40 can be easily installed on the inner peripheral side open end 4a and the outer peripheral side open end 5a when assembling the adsorption processing device 100.

After the operation of the adsorption processing device 100 , if the sealing member 430 is damaged or when it is time to replace the sealing member 430 , the sealing body 40 is disposed of as a part, so that the sealing body 40 can be easily replaced with a new sealing body 40 .
