Hereinafter, referring to the schematic diagram shown in Fig. 3, the schematic arrangement and the connection by the duct will be understood, and the spatial arrangement of the desorption equipment A and the combustion equipment B, The piping paths of the lines and the exhaust lines will be understood and understood in detail with reference to the floor plan views of FIGS. 6 to 8. FIG.

As shown in FIG. 6, the I / O facility arrangement layer 10 is a layer through which the cartridge 1 is loaded and unloaded, and includes a cartridge loading chamber 11 for loading and storing the cartridge 1 to be loaded and unloaded, 1 and a cartridge outlet room 12 for storing and delivering goods, and can be divided into left and right parts when viewed from the front of the building, so that the goods receipt operation and the goods issue work can be performed without mutual interference.

Here, the cartridge loading room 11 is provided with a carry-in elevator 13 for loading the removable cartridges 1 to be loaded and stored one by one into the desorption arrangement layer 20 of the upper layer, Is provided with a carry-out elevator (14) for loading and unloading the cartridge (1) once removed from the upper layer of the desorption facility array layer (20) 14 are aligned with the arrangement length of the desorption apparatus A described later.

Since the cartridge loading chamber 11 may be contaminated by the adsorbent material of the cartridge 1 to be detached, it is sucked and discharged by the intake duct 521 at the end of the intake line 520 of the combustion furnace 500 as described later , And is used for cooling and desorbing using the intake air at this time, and then burned in the combustion furnace.

In the embodiment of the present invention, the desorption equipment A and the combustion equipment B are arranged in two by minimizing the space occupancy of the desorption equipment A and the combustion equipment B, The air in the cartridge feed chamber 11 is caused to be aspirated and the other group aspirates the air in the cartridge outlet chamber 12 into the intake duct 521. [

Although not shown in detail in the drawing, the cartridge loading chamber 11 and the cartridge discharging chamber 12 are provided with a hoist for reversing or laying out the cartridge 1, Rail guided vehicles (RGV) or conveyors for transport, and stoker crane for lifting and transporting.

The desorption facility arrangement layer 20 is disposed above the I / O facility arrangement layer 10 as shown in FIG.

The desorption apparatus A is a facility for carrying in and out of the cartridge 1 stored in the cartridge receiving chamber 11 and carrying it out to the cartridge discharging chamber 12, (That is, the upper end structure of the carry-in elevator) from the position where the cartridge is lifted (i.e., the upper end structure of the carry-in lift) to the cartridge discharge chamber 12 A plurality of desorbers 100 sequentially connected in series and then repeatedly desorbed and then cooled through the cooler 300 before being taken out.

More specifically, between the carry-in conveyor 400 that receives the cartridge 1 from the carry-in elevator 13 and the carry-out conveyor 440 that transfers the removed and cooled cartridge 1 to the take-out elevator 14 The desorption waiting chamber 410, the plurality of desorbers 100, the cooling waiting chamber 420, the cooler 300 and the take-out waiting chamber 430 are sequentially arranged in a line.

Here, the detachment waiting room 410, the individual detacher 100, the cooling waiting room 420, the cooler 300, and the waiting-out waiting room 430 are closed by a door provided on the conveyance path of the cartridge 1 A conveyor for transferring the cartridge 1 to the adjacent room or a conveyor for passing the same through the adjacent room is individually provided in the room so that the adjacent one of the doors opens the door to transfer the cartridge 1 to the adjacent room The cartridge 1 can be sequentially transferred in such a manner that when the cartridge 1 is to be kept in each room for a predetermined time, the door can be closed to be in the closed room.

According to the embodiment of the present invention, the detacher 100 has an interior conveyor which supports the cartridges 1 at the intermediate portion for accommodating one cartridge 1 and supports both side edges of the bottom of the cartridges, A lower structure which becomes narrower toward the lower side and an upper structure which becomes narrower toward the upper side so that the air blown through the bottom side inlet of the lower structure is desorbed while passing through the solid adsorbent of the cartridge 1, And is discharged through the upper surface side outlet of the upper structure.

A plurality of such detachers 100 may be provided and connected to each other along the conveying path of the cartridge 1, but the cartridge 1 can be sequentially passed through the door between the detachers 100.

3 and 4, each of the desorbers 100 receives the air distributed by the inlet-side distribution duct 200 disposed at the lower portion thereof, and the air discharged through the upper- Side distribution duct 200a disposed in the outlet-side distribution duct 200a. The inlet-side distribution duct 200 and the outlet-side distribution duct 200a are arranged in parallel with the arrangement direction of the plurality of desorbers 100, and then are arranged in the vertical direction of the inlet or outlet of each desorber 100, To be connected to each of the detachers (100).

The cooler 300 has the same structure as the individual despooler 100, and only one cooler 300 is provided.

Here, the inlet and outlet of the inlet-side distribution duct 200, the outlet-side distribution duct 200a, and the cooler 300 are disposed on the intake line 520, which will be described later.

2, the inlet-side distribution duct 200 can be installed on the ceiling side of the I / O facility arrangement layer 10, which is a lower layer, as shown in the flowchart of FIG. 4, The outlet side distribution duct 200a is disposed in the combustion facility arrangement layer 30 which is the upper layer and is connected to the upper side of the desorber 100 A duct leading to the outlet is passed through the ceiling of the desorption facility arrangement layer (20). Thus, as can be seen from the perspective view of FIG. 2, the height of the desorber 100 in the ceiling of the desorber arrangement layer 20 can be sufficiently secured.

Likewise, the cooler 300 is also located on the bottom of the desorption facility arrangement layer 20 and on the intake line 520 piped through the ceiling.

In addition, the inlet-side distribution duct 200 is disposed in parallel with the placement line of the plurality of desorbers 100 in order to supply air at a uniform flow rate to the desorber 100 connected to each of the branch pipes 230 And the vertically oriented branch pipes 230 are disposed in order so that the diameters of the positions at which the respective separation pipes are installed are gradually reduced as the air on the intake line moves away from the inlet side, to a reducer. A branch pipe provided at an end of the inlet side distribution duct 200, that is, a branch pipe located farthest from the side where air is introduced is installed using a normal band. When the plurality of branch pipes provided here have the same diameter, the flow rate of the branch pipes installed at the end of the distribution duct 200 is relatively large, so that it is preferable that the flow rate is within the range of 90% to 93% of the other branch pipe diameters .

The desiccator of the inlet side distribution duct 200 is an eccentric reducer which is eccentric in the upper side (i.e., in the desorber direction).

The outlet-side distribution duct 200a is disposed in parallel with the arrangement line of the plurality of desorbers 100, and as shown in the figure, the air discharge direction is opposite to the air inflow direction of the inlet side distribution duct 100 .

Meanwhile, the detachment waiting chamber 410 stores the loaded cartridge 1 before it is transferred to a detacher connected to the detacher 100. The detachment waiting chamber 410 is detached from the detachment conveyor 400 in a closed state, And when it is handed over to the desorbing machine, the door in the direction of the loading conveyor 400 is closed, thereby minimizing the external discharge of air in the desorbing machine.

Likewise, the cooling chamber 420 serves to prevent direct communication between the chamber of the desorber 100 and the chamber of the cooler 300.

The take-out waiting room 430 serves to prevent direct communication between the inside and the outside of the cooler 300. That is, if the door of the cooler 300 is opened and the cartridge 1 is directly transferred to the carry-out conveyor 440, the airflow inside the cooler 300 flows to the outside. I have.

In the embodiment of the present invention, the desorption facilities A arranged in a line are additionally arranged in parallel in parallel, the distributing conveyor 400a is provided between the both side conveying conveyors 400, the both side conveying conveyors 440, The dispensing conveyor 440a is disposed between the transfer conveyor 400 and the transfer receiving conveyor 400 so as to distribute the cartridge 1 to be received from the one conveying conveyor 400 directly to the conveying elevator 13 to the both side separating apparatus A, 14 to be taken out of the two-piece dismounting facility (A) in a take-out conveyor (440).

The pressurized air blower 522 on the intake line 520, which will be described later, is disposed near the desorption apparatus A corresponding to the two-apparatus desorption apparatus A arranged in parallel.

The combustion facility arrangement layer 30 is disposed above the desorption facility arrangement layer 20 as shown in FIG.

The combustion apparatus B is a system in which the fuel supplied from the fuel supplier 501 in the combustion furnace 500 is injected with air and burned and the exhaust gas of the combustion furnace 500 is passed through the boiler 510, The exhaust line 530 (530 - 530) for supplying the exhaust gas passed through the boiler 510 to the second heat exchanger 532, the first heat exchanger 531 and the inflow blower 533 sequentially, 1, 530-2, 530-3, and 530-4, and then discharged to the air through the chimney 534 on the roof.

3, an intake line 520 (see FIG. 3) for installing piping for injecting air, which is drawn in through the intake duct 521 in the cartridge loading chamber 11, into the combustion furnace 500, 520-1, 520-2, 520-3, 520-4, 520-5 and 520-6 are connected to the cooler 300, the first heat exchanger 531, the desorber 100 and the second heat exchanger 532 ) Sequentially.

Thus, the cartridge 1 passing through the cooler 300 is cooled by the intake air and then is taken out to the cartridge discharge chamber 12, and the intake air which is first heated through the cooler 300 is discharged to the first heat exchanger The cartridge 1 can be desorbed at a low temperature by passing the desorbent 100 through the desorbent 100 after being secondarily heated by the desiccant 531.

In addition, the intake air, which has been partially desorbed in the desorption process, is secondarily heated at a high temperature by the second heat exchanger 532, and then injected into the combustion furnace 500, whereby the desorbed material introduced by the desorption process is completely burned . As a result, in addition to the heat source by the fuel supplied from the fuel supplier 501, a heat source by the desorbing material can be obtained.

Further, the inflow fan 533, which sequentially exhausts the exhaust gas to the second heat exchanger 532 and the first heat exchanger 531 and then discharges the air to the atmosphere, can pumped air having significantly lowered temperature and discharge it to the air.

Hot water supply section in which the combustion furnace 500 and the boiler 510 are arranged in a row and a heat exchanging section 530 in the exhaust line 530 through the second heat exchanger 532 and the first heat exchanger 531, Section 530-2 and the second heat exchanger 532 and the boiler 510 are connected to each other by a two-stage bending pipe, '. The interval between the combustion / hot water supply section and the heat exchange section 530-2 is preferably as narrow as possible except for the space for installation and management.

The heat exchange section 530-2 of the exhaust line 530 is vertically parallel to the arrangement line of the desorption apparatus A provided in the lower layer (i.e., the desorption facility arrangement layer 20). In this case, the upper and lower parallel arrangements do not necessarily mean that they are arranged in parallel in the vertical direction since a space for installation of the intake lines 520 must be ensured. However, only a space for installing the intake lines 520 is secured, It is good not to deviate greatly.

The first heat exchanger 531 is connected to an exhaust line that can pipe the intake line 520 with the shortest distance from the upper side outlet of the cooler 300 and the inlet of the inlet side distribution duct 200 below the desorber 100, The second heat exchanger 532 is installed on the outlet line 530 and the exhaust line 530 that can pipe the intake line 520 with the shortest distance from the exit of the outlet side distribution duct 200a on the upper portion of the desorber 100, .

By arranging the combustion device B as described above, the arrangement is relatively narrow. Thus, in the embodiment of the present invention, the two-stage combustion device B having a one-to-one correspondence to the two- . Conversely, since the combustion facility B occupying a large space has a narrow arrangement, it can be installed in two sets in the floor area of a typical building, so that the desorption facility A can be installed in two units.

The intake lines 520 (520-1, 520-2, 520-3, 520-4, 520-5, and 520-6) are connected to the intake duct 521 installed in the cartridge loading chamber 11, A first heat exchanger 531 disposed in the combustion facility arrangement layer 30 and a plurality of desorbers (not shown) provided in the desorption facility array layer 20 100, the second heat exchanger 532 installed in the combustion facility arrangement layer 30, and then connected to the combustor 500. Accordingly, the suction line 520 is piped through the floor and ceiling of the desorption facility arrangement layer 20, and will be described with reference to the perspective view of FIG. 5 and FIGS. 6 to 8. FIG.

The section 520-1 extending from the intake duct 521 to the pressurized blower 522 and the section 520-2 extending from the pressurized blower 522 to the cooler 300 absorb air at room temperature, However, in the case of the portion exposed to the desorption facility array layer 20, as shown in the plan view of FIG. 7, the desorption facility A may be used instead of the desorption facility A, It is good to make it parallel with. The position of the pressurized air blower 522 may also be determined appropriately in the vicinity of the desorption apparatus (A).

However, in the intake line 520, the section 520-3 between the cooler 300 and the first heat exchanger 531, the first heat exchanger 531, and the inlet-side distribution duct of the desorber 100 And the section 520-5 between the outlet side distribution duct 200a of the desorber 100 and the second heat exchanger 532 are piped to the shortest distance possible, It is preferable to minimize the loss and thereby minimize the temperature change of the air passing through each section and operate it stably. As described above, since the heat exchange section in which the first heat exchanger 531 and the second heat exchanger 532 are installed in the exhaust line 530 is arranged in parallel on the desorption facility A, The temperature change of the air passing through the line, that is, the temperature of the air passing through the desorber, the air passing through the cooler, and the air supplied to the combustion furnace can be minimized.

Finally, the section 520-6 between the second heat exchanger 532 and the combustor 500 in the intake line 520 is located inside the combustion facility B arranged in the U-shape (that is, Between the two installation lines), the piping should be piped at the shortest distance by the two-step bent pipe.

A flue gas NO x removal apparatus 502 using, for example, a selective non-catalytic reduction (SNCR) absorption method is disposed in the combustion facility arrangement layer 30 so as to be disposed between the combustion furnace 500 and the boiler 510 Nitrogen oxide is removed from the exhaust gas by injecting ammonia or urea into the exhaust gas passing therethrough.

The hot water supply heat exchanger 511 is connected to the hot water supply heat exchanger 511 on the circulation path where the water in the low temperature water storage tank 512 is heated by the boiler 510 and then recovered, The hot water heated by the heat supply and heat exchanger 511 is supplied to the hot water for heating in the building in which the present plant is installed, use.

The piping for installing the flue gas NO x removal apparatus 502 and the piping for supplying hot water can be installed in a conventional manner by utilizing the remaining space by installing the combustion facility B, and thus are omitted from the plan view of Fig.

Further, as an accessory facility, there is a need for a ventilation facility for improving the indoor environment of the entry / exit facility arrangement layer 10, the desorption facility arrangement layer 20, and the combustion facility arrangement layer 30. Here, since the cartridge inlet chamber 11 is discharged by the intake duct 521, it may be equipped only with a facility for blowing outside air.

It is to be noted that, in the case of two sets of the facilities including the desorption facility A and the combustion facility B, any one of them is described as using the air in the cartridge discharge chamber 12 as the air intake. However, In this case, the air in the desorption / desorption chamber 410 may be sucked together.

In the desorption apparatus arrangement layer 20 or the cartridge loading chamber 11, the cartridge 1 before being detached is exposed and the contaminants adsorbed on the cartridge 1 may be released into the room air. Way valve in the middle of the intake line for sucking the odor-eliminating gas into the odor-eliminating tower.

In order to allow the air in the desorption waiting chamber 410 to be drawn into the intake line 520, a gap is provided in the door on the side of the receiving conveyor 400 to allow intake, A method of constructing an air inlet for the door, or a method of making the air intake only when the door is opened can be adopted.

Hereinafter, the arrangement of the plurality of desorbers 100 and the structure of the individual desorbers 100 will be described in detail.

<Arrangement of the Multiple Desorbing Machine 100>

9, the plurality of detachers 100 are 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 is a distributor for distributing the low-temperature heated air heated by the first heat exchanger 531 evenly below the plurality of desorbers 100 to be simultaneously injected into each of the desorbers 100 As the duct, an arrangement (not shown) of the desiccant 100 is provided so as to be supplied with the low-temperature heating air at the lower side end of the last desorber 105 in the passage sequence of the cartridge 1 and to flow toward the lower side of the first desorber 101 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.

10 is a graph showing a flow rate deviation of the 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.

10, 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.

And a temperature sensor for sensing the temperature of the case 110 for safe operation. Although not shown, the VOCs concentration sensor may be provided with a VOCs concentration sensor for measuring the concentration of VOCs in the low temperature heated air to be injected and discharged. The VOCs concentration sensor at this time includes a pipe leading to the lower inlet 113 and a pipe connected to the upper outlet 114 .

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.

The conveyor 130 is disposed in the longitudinal direction of the casing 110 at both sides of the casing 110 (that is, in a direction perpendicular to the longitudinal direction of the casing 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

15 (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. 12 and 14, the diffusion tube 140 first has a shape of hollow truncated pyramid with an 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.

Referring to the enlarged view of a portion of FIG. 13 and the enlarged view of portion C of FIG. 15, an extension portion 141 having a predetermined length extended upward from the upper opening portion of the diffusion tube 140, 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.

16 and 17 are compared with FIGS. 12 and 13, when the diffusion tube 140 is moved up and down by the elevating 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 or lowers the flange 145 of the extension pipe 144 up and down to remove 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. 22, 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 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.

12 and 14, the guide vane 160 starts at 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.

22 and 23 are sectional views showing vertical slopes of the partition walls 161 and 162 constituting the guide vane 160 and inlet sizes of the respective divided areas.

That is, as shown in FIG. 22, a specific horizontal direction airflow is branched to the vertical direction branch pipes 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. 23, a plurality of width direction partition walls 161 provided at intervals in a direction orthogonal to the specific horizontal direction (width direction in the drawing) are symmetrically replaced.

Next, the controller 600 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.
