Description

TECHNICAL FIELD [0001] The present invention relates to a continuous adsorbent regeneration / desorption system,

The present invention relates to a method and apparatus for continuously and repeatedly passing a cartridge filled with a solid adsorbent through a plurality of desorbers to remove and regenerate harmful substances adsorbed by a solid adsorbent in a desorption apparatus in a tandem flow manner in each desorber to supply a uniform air volume to each desorber, The present invention relates to a continuous solid adsorbent regeneration / desorption system capable of uniformizing the flow of a tropical stream in a vessel, improving desorption efficiency, and stably operating the system.

Since volatile organic compounds (VOCs) are odorous and harmful to human body, they release harmful photochemical oxides that cause smog or environmental pollution by reacting with light when they are released to the atmosphere as they are. Therefore, Remove.

However, since a solid adsorbent such as activated carbon adsorbs harmful substances, the adsorbing ability gradually decreases as the adsorbed material accumulates. Therefore, the adsorbent may be replaced when the adsorbing capacity is lost to saturation. However, in order to reduce the cost, .

As a method of regenerating a solid adsorbent, there are various methods such as a high temperature heating regeneration method, a low temperature heating regeneration method, a PSA (Pressure Swing Absorption Process), a chemical regeneration method and a microbial oxidation method. However, A low-temperature heating regeneration method which uses regenerated adsorbent with less physical loss of the adsorbent, uses the recovered adsorbent as combustion fuel, minimizes the generation of dust, and uses waste heat of the exhaust gas is more efficient than other methods.

As a related art related to this regeneration method, there are the registered patent 10-1302067, the registered patent 10-1343558, and the registered patent 10-1385521.

However, the above-mentioned prior arts have been concerned with the fact that the concentration of the desorbing material during the regeneration process for desorbing volatile organic compounds (VOCs) using the tropospheric flow regulates the flow rate of the tropical stream by using a damper or a valve on the piping, The countermeasures are insufficient and no specific measures for uniformly regenerating the solid adsorbent are proposed.

That is, it operates as a heat recovery system that burns a desorbent material and supplies low-temperature heated air using exhaust gas generated by combustion. While supplying a proper amount of air to the combustion furnace, the amount of desorbed material to be combusted must be constantly supplied It is difficult to stably control both the amount of air and the amount of the desorbing material and furthermore the control of the amount of the low temperature heating air in order to control the amount of the desorbing material means that the fluctuation And even if a separate air supply means is installed in the combustion furnace as in the case of the Japanese Patent No. 10-1385521, there is a difficulty in safe operation.

Further, when the regeneration process is carried out in units of cartridges filled with the solid adsorbent, the entire solid adsorbent in the cartridge must be uniformly regenerated, and concrete measures for this are lacking.

The cartridge 1 to be introduced into the continuous solid adsorbent regeneration / desorption system according to the embodiment of the present invention to be subjected to the regeneration processing process is described in detail in, for example, Japanese Patent No. 10-1302067, 3 and cross-sectional view (4).

The cartridge 1 is formed in a rectangular parallelepiped shape and has a ventilation hole 1a in which the mesh net 1b is fitted to the upper and lower surfaces thereof so that the solid adsorbent 1c filled in the cartridge 1 can be desorbed And can be conveyed or supported by the conveyor using the outer rim of the lower ventilation hole 1a on the bottom surface side. That is, the cartridge disclosed in Japanese Patent No. 10-1302067 can be considered as a structure in which the cartridge is laid out.

Here, the solid adsorbent 1c may be composed of, for example, activated carbon adsorbing volatile organic compounds (VOCs). The cartridge 1 for filling the solid adsorbent 1c may be installed on the adsorption tower to adsorb toxic substances And when the adsorption performance decreases as the adsorption amount of the harmful substance increases, it is necessary to perform a regeneration treatment for desorbing the adsorbed harmful substance to restore the adsorption performance.

The present invention relates to a continuous solid adsorbent regeneration / desorption system for regenerating such a cartridge (1), wherein the regeneration method of the solid adsorbent (1c) is regenerated by hot air of air heated at a low temperature, for example, Temperature regeneration method is applied

Hereinafter, a continuous solid adsorbent regeneration / desorption system according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings and will be easily understood by those skilled in the art.

3 and FIG. 3, the continuous solid adsorbent regenerating / desorbing system according to the embodiment of the present invention continuously transports the cartridges 1 one by one and continuously discharges the cartridges 1 by hot air of low- (4) for desorbing and recycling the harmful substances adsorbed on the solid adsorbent (1c) of the adsorbent (1c) and then carrying out the regeneration, and for supplying the low temperature heating air to the desorption apparatus (3) And a controller 2 for controlling the continuous regeneration operation of the desorption facility 3 and the combustion operation of the combustion facility 4. [

The combustion device 4 mixes the fuel supplied from the fuel supplier 501 with the air sucked through the intake line 520 and burns it in the combustion furnace 500. The exhaust gas generated at this time is discharged to the exhaust line 530, As shown in FIG.

Here, the boiler 510, the second heat exchanger 532, the first heat exchanger 531, and the inflow blower 533 are sequentially disposed in the exhaust line 530, so that the exhaust gas of the combustion furnace 500 The air is sucked in the inflow air blower 533 to be discharged to the atmosphere so as to sequentially pass through the boiler 510, the second heat exchanger 532, and the first heat exchanger 531. Thus, the exhaust gas of the combustion furnace 500 can be heated by hot water heat-exchanged via the boiler 510, the temperature is lowered by the heat exchange at this time, and then the second heat exchanger 532 and the first Exchanges heat with the intake air while sequentially passing through the heat exchanger 531, and is discharged to a low temperature suitable for air discharge.

The intake line 520 is piped so as to supply the outside air to the combustion furnace 500 by sucking the outside air into the pressurized air blower 522. The intake air sucked and fed by the pressurized air blower 522 is supplied to the cooler 300, After passing through the heat exchanger 531, the inlet-side distribution duct 200, the plurality of desorbers 100, the outlet-side distribution duct 200a and the second heat exchanger 532 to be described later, . Here, it is preferable that the intake air is air in the reservoir in which the cartridge 1 to be regenerated is received.

By piping the intake line 520 as described above, the cartridge 1, which is regenerated by the desorber 100 as described later, is cooled by the cooler 300 that allows the cartridge 1 to pass immediately before it is taken out. At this time, Temperature heated air suitable for regenerating the cartridge 1 while passing through the first heat exchanger 531 and then distributed to the respective desorbers 100 by the inlet side distribution duct 200. [ The intake air passes through each desorber 100 and the harmful substances adsorbed to the solid adsorbent 1c of the cartridge 1 are desorbed and mixed and then joined by the outlet side distribution duct 200a to be introduced into the second heat exchanger 532 to the combustion furnace 500 in a heated state at a suitable high temperature for combustion.

At this time, harmful substances mixed in the intake air are heated at a high temperature by the second heat exchanger 532, and are burned well in the combustion furnace 500 to be used as combustion fuel.

The combustion device 4 configured as described above not only supplies the hot air of the low-temperature heated air for the regeneration process of the cartridge 1 in the desorber 100, but also performs the cooling process before the regenerated cartridge 1 is shipped And uses the harmful substances generated in the regeneration process as the fuel of the combustor 500, thereby saving the fuel to be supplied from the fuel supplier 501. [

Referring to the sectional view of the desorption apparatus 3 shown in Fig. 4 together, the desorption apparatus 3 will be described.

The desorption apparatus 3 includes a desorption waiting chamber 410 in which the cartridges 1 are received one by one at a time interval from the carry-in conveyor 400 that receives the cartridge 1 to be regenerated, 102, 103, 104, and 105, the cooling standby chamber 420, the cooler 300, and the take-out waiting chamber 430 in order.

Each of the detachers 100, 101, 102, 103, 104, and 105 is configured to carry one cartridge 1 to an intermediate portion of the indoor space, blow low temperature heated air from the lower side to be discharged upward, Temperature heated air of the cartridge 1 passes through the upper air vents 1a of the cartridge 1 and passes through the solid windproofing agent 1c to detach the harmful substances and mix the detached harmful substances with the rising air of low temperature to be discharged to the upper side , And such a detachment process is carried out for a time period controlled by the controller 2, and then removed.

Each of the despoolers 100 is provided in a plurality and is arranged in a line so as to sequentially open and close the door 170 between the doors. Of course, the doors 170 are also provided at the first inlet and the last outlet of the pass-through sequence, so that the respective desorbers 100 can individually perform desorption / regeneration. Thus, the cartridge 1 is repeatedly inserted and removed while sequentially passing through the respective desorbers 100, and the regeneration is completed.

In addition, as will be described in detail below with respect to the structure of the desiccant 100, the low-temperature heating air blown from the lower side passes through the diffusion tube 140 partitioned by the grid vane guide vanes 160, Side vents 1a of the cartridge 1, and are distributed by the guide vanes 160 to pass the cartridge 1 in a uniform direction. Therefore, the entire amount of the solid adsorbent 1c in the cartridge 1 can be desorbed evenly.

The inlet side distribution duct 200 distributes the low temperature heated air heated by the first heat exchanger 531 evenly below the plurality of desorbers 100 and causes them to be simultaneously injected into each despooler 100 As the distribution duct, the low-temperature heating air is supplied at the lower side end of the last desorber 105 in the order of passage of the cartridge 1, so as to flow toward the lower side of the first desorber 101 And arranged parallel to the array line.

The inlet side distribution duct 200 distributes the low temperature heating air sequentially from the last desorber 105 to the first desorber 101 and branches the upstream side of the branch pipes 231, 232, 233, 234, And the first bellows 235 is connected to the branch pipe 235 through the normal band 220 by providing a normal bend 220 on the end side. The band 220 and the branch pipe 235 to be injected thereinto.

In addition, the inlet-side distribution duct 200 gradually reduces the diameters of the points where the branches 231, 232, 233, 234, 235 are connected by the reducer 210, which is an eccentrically- Thereby equalizing the air flow rate.

The diameter of the branch pipe 235 of the last order branched through the normal band 220 is larger than the diameter of the branch pipes 231, 232, 233, 234 branched from the last separator 105 to the second separator 102 ) To be in the range of 90% to 93% of the diameter.

5 is a graph showing the flow rate variation of branch pipes 231, 232, 233, 234, 235, which are sequenced according to the branching order of the low-temperature heating air in the inlet side distribution duct 200, with different diameters of the last branch pipe 235. Since the order of the branch pipes 231, 232, 233, 234 and 235 follows the branching order, the order of the detachers 100 (101: 101, 102, 103, 104 and 105) In reverse order.

5, when the diameter of the last branch pipe 235 is made equal to the diameter of the remaining branch pipes 231, 232, 233, and 234, ) Is relatively large.

If the diameter of the last branch pipe 235 is 95% of the diameter of the remaining branch pipes 231, 232, 233 and 234, that is, the pipe diameters of the remaining branch pipes 231, 232, 233 and 234 are multiplied by 0.95, The flow rate deviation of the last branch pipe 235 is still large although the flow rate deviation per branch pipe is reduced.

However, when the diameter of the last branch pipe 235 is set within the range of 90% to 93% of the diameters of the remaining branch pipes 231, 232, 233 and 234, the total length of the branch pipes 231, 232, 233, 234 and 235 Flow variance is generally small. Particularly, when the diameter of the last branch pipe 235 is 91% of the diameter of the remaining branch pipes 231, 232, 233, and 234, the flow rate deviation is the least.

As the diameter of the last branch pipe 235 is made smaller than 90% of the diameters of the remaining branch pipes 231, 232, 233 and 234, the flow rate of the last branch pipe 235 becomes smaller and the deviation becomes larger.

Therefore, it is most preferable that the diameter of the last branch pipe 235 is 91% of the diameter of the remaining branch pipes 231, 232, 233, and 234.

The outlet-side distribution duct 220a is disposed on a plurality of the desorbers 100 in parallel with the arrangement line of the desorber 100 and is disposed on the upper side of each deaerator from the last desorber 105 to the first desorber 101. [ And receives and discharges the low temperature heated air discharged to the outlet. That is, the outlet-side distribution duct 220a has an end where the last desorber 105 is connected is blocked, and the end of the portion where the first desorber 101 is connected passes through the second heat exchanger 532 And extends to a section of the intake line 520 that continues to the combustion furnace 500.

At this time, the exit-side distribution duct 220a has a diameter larger than the diameter of the branch pipes to be connected to the upper side of each of the desorbers 100 one by one. Although not shown in the figure, the inlet-side distribution duct 200 But may be arranged in a reverse direction so as to gradually increase the diameter (that is, a portion connected to the branch pipe) from the clogged end to the other end communicating with the second heat exchanger 532.

The cooler 300 differs in that the components other than the lifting and lowering means 150 are the same as the components of the despooler 100 described below. The upper guide roller 115, the lower guide roller 153, the flexible sealing member 146 and the expansion / contraction annular pipe 147 are also unnecessary because the elevating means 150 is not provided. The inlet 110 of the case 110 may be fitted into the lower inlet 113 of the case 110 and then the inlet line 520 may be pierced.

The cooler 300 configured as described above blows the intake air by the inflow fan 533 from the lower side and discharges the air to the upper side in a state where the cartridge 1 which is turned over in the cooling standby chamber 420 at the front end is accommodated therein, The cartridge 1 which has been heated by the low temperature heating air in the desorption / regeneration process by the desorber 100 is cooled by the intake air, cooled for a time controlled by the controller 2, and then transferred to the takeoff waiting chamber 430. In addition, the solid adsorbent 1c of the cartridge 1 can be uniformly cooled by having the structure of the desorber 100 described later.

The detachment waiting chamber 410 disposed at the front end of the first detacher 101 in the order of passage of the cartridge 1 opens and closes the door 411 and receives the cartridge 1 to be detached and reproduced from the conveying conveyor 400, The cooling standby chamber 420 disposed between the last detacher 105 and the cooler 300 opens and closes the door 170 from the last detacher 105, The door 310 is opened and closed to the cooler 300 after the door 310 has been handed over temporarily to the take-out waiting room 430 disposed at the rear end of the cooler 300, So that the cartridge 1 is handed over and temporarily stored, and then the door 431 is opened and closed and handed over to the carry-out conveyor 440 to be taken out.

Here, the temporary storage time of each waiting room is controlled by the desorption / regeneration time in the individual despooler 100, so that the desorption facility 3 continuously takes in the cartridges 3 one by one and regenerates them.

The temperature sensor 120, the pressure sensor 121, and the VOCs concentration sensor that sense the low temperature heated air before and after passing through the cartridge 1 operate the elevating means 150 described later to detect the inside of the cartridge 1 , And a sensor for controlling the amount of air passing through the solid adsorbent 1c.

The upper hopper of the case 110 is provided with an explosion-proof vent 122 and an extinguishing agent injection head 123. Briefly, the explosion / discharge aperture 122 is a known component, so that when the substance desorbed from the solid adsorbent 1c is ignited by overheating, the pressure in the room rises rapidly and may be destroyed. And is opened by the pressure due to the explosion to rapidly lower the room pressure. The extinguishing agent spraying head 123 is for spraying nitrogen gas, for example, into the case 110 when the detached toxic substance is ignited.

The lower hopper of the case 110 is preliminarily provided with an inspection port 124 for internal inspection. At this time, it is preferable that the inspection port 124 has the function of an explosion-proof opening.

The case 110 includes a conveyor 130 for carrying the interior of the cartridge 1 into and out of the room and a low temperature heated air flowing into the room through the lower inlet 113 to the bottom side ventilation opening The temperature of the low temperature heating air passing through the solid adsorbent 1c through the ventilation hole 1a on the bottom side of the cartridge 1 is raised and lowered to raise and lower the diffusion tube 140, Means 150 and a guide vane 160 mounted in the diffusion tube 140 for guiding the low-temperature heating air to blow evenly over the entire surface of the bottom side ventilation hole 1a of the cartridge 1, The upper case 111 and the lower case 112 are divided and assembled after being divided into upper and lower portions at an appropriate height of an intermediate portion for installation of the elements.

As can be seen in detail in FIGS. 9 and 10, the enlarged view of FIG. 13, and the enlarged view of FIG. 14, the conveyor 130 can be moved in the longitudinal direction from both sides of the case 110 (The direction in which the spur gear 132 is oriented in the width direction (that is, the direction orthogonal to the longitudinal direction on the horizontal plane)) of the spur gear 132, The roller 131 passing through the case 110 is fixed to the axis of the spur gear 132 one by one and one of the spur gears is rotated by the motor 133 on both sides, The spur gear 132 can be rotated, and the rollers 131 rotate in the same direction. That is, the roller gear 132a having the roller 131 fixed thereto is supported by the interlocking gear 132b, which is disposed between the roller gear 132a and is not fixed to the roller 131, do.

Here, the roller 131 passing through the case 110 on both sides in the width direction is supported by the case 110, for example, by a bearing and rotatable, and the end of the roller 131 is pushed into the case 110, ) To support both sides of the width in the width direction. Thus, the cartridge 1 can be carried in and out while being rotated by the motor 133, and the low-temperature heating air (air) to be passed through the cartridge 1 It does not affect the airflow of

12 (c), the length of the roller 131 is appropriately set so as to support the bottom edge of the cartridge 1 with the roller 131 at the outer periphery of the upper end structure of the diffusion tube 140 described later Respectively.

When the cartridge 1 is brought into the room by the conveyor 130, the upper end opening of the diffusing pipe 140, which will be described later, is positioned at exactly the bottom vent opening 1a of the cartridge 1, And a position sensor for stopping the carry-in operation. Since the position sensor is a conventional sensor for sensing the cartridge 1 when it reaches a specific position, detailed description thereof is omitted. Of course, it is also possible to set the operating time of the conveyor 130 (that is, the number of rotations of the roller) according to the position at the time of receiving the cartridge 1 from outside the case 110, have.

Referring to the cross-sectional view of FIGS. 7 and 9, the diffusion tube 140 first has a shape of hollow truncated pyramid with open top and bottom, and is spaced apart from the inner wall of the bottom case 112 at a predetermined interval The size and shape of the upper opening are adapted to the size and shape of the rectangular ventilation hole 1a of the cartridge 1 and the lower inlet 113 of the case 110 is sealed And has a cylindrical structure that passes through with sufficient space. In addition, the lower cylindrical structure of the diffusion tube 140 is connected to the extension tube 144 at the lower exposed portion.

Of course, the diffusion tube 140 should have a cylindrical structure gradually passing from the upper part to the lower part by progressively forming a cylindrical structure through the circular lower inlet.

8, an enlarged portion 141 is formed by extending an upper opening portion of the diffusion tube 140 upward by a predetermined length, and an upper portion of the extended portion 141 And a sealing member 143 inserted into the upper surface of the tight fitting portion 142 formed on the upper surface of the tight fitting portion 142 after the groove is formed along the rim. The upper side opening is made to communicate with the vent hole 1a on the bottom surface side of the cartridge 1 while sealing the tight contact portion 142 with the bottom edge of the cartridge 1 to seal the lower portion of the cartridge 1. In this state, Temperature heated air injected through the extension pipe 144 connected to the lower portion of the cartridge 1 and blowing the entire amount of the air to the lower ventilation hole 1a of the cartridge 1 without leakage.

Since the contact portion 142 abuts against the bottom edge of the cartridge 1 along with the rollers 131 on both sides in the width direction, the bottom edge of the cartridge 1 is slightly spaced from the roller 131, As shown in Fig.

On the inner surface of the lower case 112, an upper guide roller 115 to be brought into close contact with the four outer surfaces of the extension portion 141 of the diffusion tube 140 is supported by the bracket 115a, 131 so as to guide upward and downward movement of the diffusion tube 140. The upper guide roller 115 at this time is formed so as to be long along the outer surface of the extension portion 141, thereby guiding the diffusion tube 140 stably so as not to be tilted to one side when lifting the diffusion tube 140.

A flexible tubular sealing material for connecting the outer circumferential surface of the portion penetrating the lower inlet 113 of the case 110 to the lower inlet 113 of the case 110 in the outer circumferential surface of the lower cylindrical structure of the diffusion tube 140, And the airtightness in the case 110 is maintained even when the diffusion tube 140 is moved up and down. The flexible sealing member 146 surrounds the outer peripheral surface of the lower cylindrical structure of the diffusion tube 140 at the lower opening and surrounds the outer peripheral surface of the lower inlet 113 of the case 110 at the upper opening, And keep it secret.

The expansion tube 144 is provided at the lower end of the extension tube 144 and is connected to the branch tube 230 via the tube 147 so that the extension tube 144 can be moved up and down do.

The extension pipe 144 is provided with a flange 145 which can be lifted and lowered by the lifting means 150 on the outer circumferential surface of any one of the portions exposed under the case 110.

7 and 8, when the diffusion tube 140 is lifted and lowered by the lifting means 150, the flexible sealing member 146 is folded or stretched, It is possible to freely allow the lifting and lowering movement and maintain the airtightness.

The lifting means 150 lifts up or down the flange 145 of the extension pipe 144 to move the diffusion pipe 140 in the case 110 And adjusts the interval between the close contact portion 142 of the diffusion tube 140 and the bottom edge of the cartridge 1 facing each other. That is, the air volume passing through the ventilation hole 1a of the cartridge 1, that is, the air volume passing through the solid adsorbent filled in the cartridge 1, is regulated.

According to a specific embodiment of the elevating means 150, the flange 145 of the extension pipe 144 is lifted or lowered by a lift 152 which is operated by a forward / reverse motor 151. The lift 152 may include a pinion 152b that rotates in the forward and reverse directions and receives a rotational force of the forward and reverse motors 151 by a belt and a rack 152a that fixes an upper end of the shaft on the bottom surface of the flange 145.

By adjusting the height of the diffusion tube 140 by the lifting means 150 as described above, the upper edge of the diffusion tube 140 (tight contact portion provided with the sealing material) and the lower edge of the cartridge 1 The temperature of the low temperature heating air passing through the cartridge 1 can be adjusted in such a manner as to adjust the air flow rate of the artificial leakage path that bypasses the cartridge 1. [ Of course, if the upper edge of the diffusion tube 140 and the lower edge of the cartridge 1 are brought into close contact with each other, the low temperature heated air to be injected can be passed through the cartridge 1 without leakage.

A plurality of lower guide rollers 153 for guiding upward and downward movement are disposed at the positions where the elevating means 150 is installed so as to cooperate with the upper guide rollers 115, 144 steadily guide the lifting and lowering motion of the diffusion tube 140 that is pivoted.

As shown in FIG. 17, the guide vane 160 is a component fixedly installed inside the diffusion tube 140. The guide vane 160 uniformly diffuses the low-temperature heating air and supplies the air passing through the vent hole 1a of the cartridge 1 Thereby making the air volume uniform.

That is, the guide vane 160 has partition walls 161 and 162 dividing the mutually facing slopes into a plurality of regions in a diffusion tube 140 having a pyramidal shape and a circular flat cross-section going downward And the angle of inclination of the partition wall toward the slope is relatively increased as the distance from the center of the low temperature heating air passage region is relatively increased so that the divided small regions are individually formed into a diffusion tube shape A grid structure is formed.

More specifically, the partition defined by the widthwise barrier ribs 161 in the partition walls 161 and 162 is partitioned by the longitudinal barrier ribs 162, and the partition walls facing the slope surfaces Tilt at a small angle relative to the vertical line, and reduce the tilting angle for the bulkheads far from the slope.

7 and 9, the guide vane 160 starts from a relatively higher position than the lower opening of the diffusion tube 140 and occupies a relatively lower position than the upper opening, So that the guide vane 160 has a space above and below the guide vane 160, respectively. That is, the low-temperature heating air that has entered the diffusion tube 140 through the lower opening portion is divided and diffused into the small region partitioned by the guide vane 160 while passing through the lower clearance space, and passes through the guide vane 160 The airflow passing through the respective small regions is mutually influenced by the air pressure in the direction guided by the respective small regions when passing through the guide vane 160, The air flow passing through the bottom ventilation hole 1a of the main body 1a is made more uniform as a whole.

According to a specific embodiment of the present invention, the guide vane 160 is configured to be in conformity with the state of the pipe which is in contact with the extension pipe 144 of the diffusion pipe 140 via the expansion / So that the air is passed through the cartridge 1 with a more uniform air volume.

17 and 18 are sectional views showing vertical slopes of the partition walls 161 and 162 constituting the guide vane 160 and inlet sizes of the respective partitioned areas.

That is, as shown in FIG. 17, a specific horizontal direction airflow is branched to the vertical direction branch pipe 230 in the inlet side distribution duct 200 lying in the horizontal direction, and flows into the desorber 100.

As a result, the lower end of the barrier ribs spaced apart from each other in the specific horizontal direction is adjusted to a position tilted in the specific horizontal direction so as to have an asymmetrical slope value, .

That is, the lower inlet of each of the diffusion paths partitioned by the guide vane 160 is tilted toward the branch flow direction in the inlet-side distribution duct 200 and is reduced.

Since the specific horizontal direction is opposite to the loading / unloading direction of the cartridge 1, the lower end of the longitudinal barrier rib 162 is slightly shifted in that direction, and the longitudinal direction The interval between the barrier ribs 162 is relatively narrow with respect to some barrier ribs near the ends of the barrier ribs 162, so that the plurality of longitudinal barrier ribs 162 have an asymmetrically inclined angle.

The slopes of the longitudinal barrier ribs 162 shown in the figure are obtained according to the result of the flow analysis using, for example, a CFD (Computational Fluid Dynamics) tool.

On the other hand, as shown in Fig. 18, a plurality of width direction partition walls 161 are provided symmetrically with respect to each other in a direction orthogonal to the specific horizontal direction (width direction in the drawing).

&Lt; Controller (2) >

Next, the controller 2 will be described.

The controller 2 controls each door of the desorption apparatus 3 in a state in which fuel supply by the fuel supplier 501, intake by the pressurized air blower 521, and exhaust by the inflow fan 533 are controlled, 411, 170, 310 and 431, the desorption waiting chamber 410, the desorbing machine 100, the cooling waiting chamber 420, the cooler 300 and the take-out waiting chamber 430, The cartridge 1 delivered from the conveying conveyor 400 is passed through the desorption waiting chamber 410, each of the desorbers 100, the cooling waiting chamber 420, the cooler 300 and the take-out waiting chamber 430 in that order, To the conveyor 440. Here, the predetermined time is preset as the time for the cartridge 1 to remain in the individual detacher 100 for detachment.

The controller 2 also has a function of preventing direct communication between the first desorbent 101 and the outside air, direct communication between the final desorber 105 and the cooling standby chamber 420, and direct communication between the cooler 300 and the outside air The cartridge 1 is sequentially passed through the respective desorbers 100, 101, 102, 103, 104, 105 and the cooler 300,

In other words, as shown in Fig. 2, in the state in which the cartridge 1 is inserted into each room, the take-out waiting room 430 takes out the cartridges in the closed state with the door between the door and the cooler 300, When the cartridge is moved between the adjacent chambers, only the space between the adjacent chambers is communicated. Next, the detachment waiting chamber 410 is moved in a state in which it is not in communication with the first detacher 101, ) Into the room.

Here, after the cartridge of the last detacher 105 is transferred to the cooling waiting chamber 420, the doors between all of the detachers 100, 101, 102, 103, 104, 105 are opened, And then transfer the cartridge of the take-out waiting room 430 to the first detacher 101.

On the other hand, the controller 2 performs the following control for safety and stability.

The controller 2 controls the amount of the air passing through the solid adsorbent 1 to decrease as the passage order of the cartridges 1 is advanced to the elevating means 100 provided at each of the desorbers 100: 101, 102, 103, 104, (150).

That is, the distance between the bottom edge of the cartridge 1 and the upper close contact portion 142 of the diffusion tube 140 becomes relatively larger in advance of the passage sequence of the cartridge 1, Reduce the air volume to be injected.

As a result, a large amount of the substance adsorbed on the solid adsorbent 1c of the cartridge 1 is left in the cartridge 1, , 103, 104, and 105, and minimizes the visual fluctuation of the amount of desorbed material supplied to the furnace through the outlet-side distribution duct 200a, so that the operation of the furnace, that is, , It is possible to perform safe and stable operation that minimizes temporal variation with respect to the heat quantity of the exhaust gas of the combustion furnace. Also, the problem that the first desorbing device 101 generates a high-density desorbing material and explodes is solved.

The amount of air passing through the solid adsorbent 1c is not only differentiated between the desorbers 100: 101, 102, 103, 104 and 105 but also reduced by the individual desorbers 100: 101, 102, 103, 104, 105), adjust the air volume as follows.

The controller 2 calculates the difference in VOCs (volatile organic compound) concentration between the low temperature heating air to be injected and the low temperature heating air to be injected, the temperature difference or the like, for each of the detachers 100: 101, 102, 103, The elevating means 150 provided in each of the desorbing devices 100: 101, 102, 103, 104 and 105 is individually controlled so as to make the pressure difference uniform. That is, the elevating means 150 is controlled so as to minimize the variation of the difference between the injection air temperature and the exhaust temperature from the detection value of the temperature sensor 120, the pressure sensor 121, or the concentration sensor with the lapse of time, 1c. When the cartridge 1 is placed in each of the desorbers 100, 101, 102, 103, 104, 105, the amount of desorbed material by hot air gradually decreases with time. However, By adjusting the airflow rate, the amount of desorbed material can be kept substantially constant for the predetermined time (the time the cartridge remains in the individual desorber).

In addition, as described in Patent No. 10-1302067, when the toxic substances desorbed are burned to be used as a heat source, the amount of the combustion fuel must be controlled in accordance with the concentration of the toxic substances, It is difficult to control the combustion fuel, a fire due to overheating may occur, and the temperature change of the exhaust gas also fluctuates greatly. In addition, there is a risk of explosion due to the generation of toxic substances at a high concentration in the early stage of the regeneration desorption process even in the room of the desorber. That is, in the regeneration desorption process, the concentration of the toxic substances desorbed is made uniform or moderately fluctuating to an appropriate value as much as possible, and the time required for sufficient desorption depends on the amount of the toxic substances adsorbed on the solid adsorbent 1c It is preferable to set it variably.

Of course, there is a method in which a damper is provided in a pipe to adjust the air volume. However, if this method is employed, the amount of air supplied to the combustion furnace that burns desorbed harmful substances also fluctuates.

Thus, in the present invention, the amount of low-temperature heating air to be injected into each of the desorbers is controlled to be substantially constant, and the amount of air passing through the solid adsorbent 1c is adjusted according to the difference in temperature, pressure difference or VOCs concentration , And the temporal fluctuation of the desorption amount is reduced.

Since the temperature difference of the low-temperature heating air reflects the air volume of the low-temperature heating air passing through the solid adsorbent 1c, it can be used not only for predicting the desorption amount but also for controlling the air volume.

Since the pressure difference of the low-temperature heating air also reflects the air volume of the low-temperature heating air passing through the solid adsorbent 1c, it can be used for predicting the amount of desorption to be used for air volume control and also for preventing explosion.

On the other hand, even if it is controlled to minimize the temporal fluctuation of the amount of the desorbing material flowing into the combustion furnace 500 as described above, it is difficult to keep the amount of the desorbing material constant. Therefore, It is preferable to control the fuel supplier 501 so as to stabilize the amount of heat generated in the combustion furnace 500 by adjusting the fuel supply amount.

On the other hand, a VOCs concentration sensor, a temperature sensor or a pressure sensor is provided at the outlet side of the outlet side distribution duct 200a to measure the concentration of the volatile organic compound in the low temperature heated air discharged from the outlet side distribution duct 200a, Or to control the elevating means 150 provided in each of the desorbing devices 100: 101, 102, 103, 104 and 105 so that the pressure becomes uniform. In this case, it is possible to increase the air flow rate at the same time or simultaneously lower the air flow rate for each desorber.
