Although volatile organic compounds (VOCs) have occurred naturally in soil, wetlands, vegetation, and land, some of them are rapidly decomposed or processed due to the rapid increase in the amount of artificially generated VOCs. Beyond the extent possible, a variety of techniques have been researched, developed and used to remove and process these VOCs.

The sources of VOCs are very diverse, and in particular, the method of removing VOCs varies according to constituent materials and VOC generation environment. More specifically, in selecting a VOC removal device, removal efficiency, ease of operation and maintenance, safety, economy, type and composition of exhaust gas, process variables, device location, calorific value, presence or absence of catalyst poison, waste heat Purpose of use, recovery and recycling should be considered. As such, an optimal VOC removal device should be selected based on various factors. As a current VOC removal device, a direct combustion device, a regenerative combustion device, a catalytic combustion device, a cooling condensation device, an absorption device, a device using a membrane separation method, and an adsorption method There are a wide variety of devices, such as using a device, absorption (cleaning) deodorizing device, biological deodorizing device and the like.

Among these, in particular, VOCs generated at industrial sites are often generated from organic solvents used at industrial sites. Conventionally, many methods of decomposing and decomposing VOCs have been used. Recently, a method of recovering and using a solvent, which is a raw material that causes VOCs, has become popular. The use of such a method saves the cost of decomposing the VOC and increases the economics by recovering and recycling the raw materials. Thus, the spread of the recovery method is gradually expanded.

The purge gas outlet 22 is formed to correspond to each of the remaining adsorption rooms except the adsorption room in communication with the first cooling chamber 20a and the adsorption room in communication with the first desorption chamber 20c. Therefore, when eight adsorption rooms of the present invention are formed, the cooling air outlet 21 and the desorption air inlet 23 correspond to one adsorption room, respectively, and the purge gas outlet 22 is the other six adsorption rooms. It is configured to correspond with the room. In the center of the first chamber 20, a first rotor shaft space 24 for inserting the rotor shaft of the rotor 10 may be formed through both sides of the first chamber 20.

In this case, as shown in FIG. 9, the outer surface 12 of the rotor 10 is formed thick enough to always contact the second and fifth sealing members 52 and 55 when the rotor 10 rotates. It is preferable to be. This is because the outer surface 12 of the rotor 10 is formed in the shape of a polygon rather than a circle.

In addition, the third and sixth sealing members 53 and 56 may be formed thicker than the second and fifth sealing members 52 and 55. As shown in FIG. 10, the adsorption room R includes the cooling chambers 20a and 30a and the adsorption chambers 20b and 30b, the adsorption chambers 20b and 30b, and the desorption chambers 20c and 30c or the desorption chamber. When located between 20c and 30c and the cooling chambers 20a and 30a, the flow of gas or air is limited to the partition 15 through the partition 15 to prevent the movement of gas or air between the chambers and the chamber. Done. At this time, the separation distance (L) of the partition 15 should be formed to be equal to or shorter than the thickness (T) of the third and sixth sealing members (53, 56) to prevent the movement of gas or air between the chamber and the chamber. It becomes possible. Therefore, when the thickness T of the third and sixth sealing members 53 and 56 is thin, the number of the partitions 15 may increase because the separation distance L of the partitions 15 should be short. There is no choice but to.

An embodiment of the third and sixth sealing members 53 and 56 to solve this problem is illustrated in FIG. 11. As the first to sixth sealing members 51, 52, 53, 54, 55 and 56, it is preferable to use a high temperature rubber that can withstand 200 degrees Celsius or more.

The second sealing member 52 is effective because the inner hole 52a is formed at a point close to the upper contact surface of the rotor 10 and is deformed under load from the rotor 10 to increase the contact area with the rotor 10. Surface contact becomes possible. The second sealing member 52 is fixed to the other surface of the first chamber portion 20 by the fixing bracket 61 to the fifth sealing member 55 on one surface of the second chamber portion 30. The third sealing member 53 may be configured by making the two second sealing members 52 symmetrical, and a gap may be filled between the sealing members by using a high temperature sealant. The third sealing member 53 is effective because the inner hole 53a is formed at a point close to the upper contact surface of the rotor 10 and is deformed when the load is received from the rotor 10 to increase the contact area with the rotor 10. Surface contact becomes possible. In particular, since the inner hole 53a of the third sealing member 53 has a diameter about twice as large as the diameter of the inner hole 52a of the second sealing member 52, the surface contact effect due to the increase of the contact area. Is doubled. Since the third sealing member 53 is manufactured in one piece without a gap, the third sealing member 53 is easily installed without cracking even when used for a long time.

Referring to FIG. 12, proximity sensors 71 and 72 may be installed on the first chamber 20 or the second chamber 30. Although the proximity sensors 71 and 72 are shown to be installed on the first fixed disk 25 which extends to the outside of the first communication hole H1, the proximity sensors 71 and 72 extend to the outside of the second communication hole H2. It may be provided in the second fixed disk 35 to be formed. The proximity sensors 71 and 72 may include a rotation position proximity sensor 71 and an exact position proximity sensor 72. The proximity sensors 71 and 72 may recognize the difference due to the distance difference when the bent portion of the rotor 10 passes through the proximity sensor, thereby controlling the rotation speed of the rotor 10 through the rotation position proximity sensor 71. . In addition, when the outer surface of the adsorption room (R) is positioned horizontally to the ground when charging the adsorbent, which is pellet-like, into the adsorption room (R), the adsorption of the adsorbent is facilitated. Each adsorption room (R) of) can be stopped at a predetermined position.

Hereinafter, the operation of the present invention configured as described above will be described with reference to the drawings.

The adsorbent in which the VOC is adsorbed is positioned between the first desorption chamber 20c and the second desorption chamber 30c by the rotation of the rotor 10, and the hot air introduced through the desorption air inlet pipe 3 is absorbed. The VOC is desorbed through and the concentrated VOC is discharged through the concentrated VOC discharge pipe (6). In this case, when the adsorption room R is located between the adsorption chamber and the desorption chamber, the separation distance L of the partition 15 is equal to or greater than the thickness T of the third and sixth sealing members 53 and 56. Due to the configuration of the adsorption room R, the gas or air in the adsorption room R may be prevented from moving between the chambers.

The adsorbent in which the VOC is desorbed is positioned between the first cooling chamber 20a and the second cooling chamber 30a by the rotation of the rotor 10, and the air is introduced through the cooling air inlet pipe 4. The adsorbent is cooled to regain the adsorption performance. In addition, when the adsorption room (R) is located between the desorption chamber (20c, 30c) and the cooling chamber (20a, 30a) the gas or air in the adsorption room (R) by the partition 15 between the chamber and the chamber. This will prevent movement in.

The adsorbent having the adsorption function is positioned between the first adsorption chamber 20b and the second adsorption chamber 30b by the rotation of the rotor 10 to repeat the above process.
