Description

A pollution gas removal device, a monitoring system and a method of the pollution gas removal device

The present invention relates to a pollutant removal device and a monitoring system and method for the pollutant removal device. More particularly, the present invention relates to a pollutant removal device for efficiently removing a pollutant gas contained in a syngas, And the state of the adsorption column can be informed without any field personnel by detecting the presence of contaminant gas in the gas discharged from the pollutant gas removing device for removing the contaminant gas contained in the syngas, A contaminated gas removing device, and a monitoring system and method of the polluted gas removing device.

In order to purify the polluted gas containing organic solvents and the like discharged from chemical plants and the like, a polluted gas treatment apparatus using adsorbents such as granular activated carbon, fiber-type activated carbon or zeolite is mainly used. In order to maintain the adsorbing ability of these adsorbents, it is necessary to carry out a regeneration operation by steam or hot gas. In order to continuously treat the gas to be treated, a plurality of adsorption apparatuses are used to perform adsorption and regeneration operations alternately Has come.

An adsorption apparatus using a fibrous activated carbon comprises a cylindrical adsorption element in which a fibrous activated carbon felt is laminated on an air permeable core material and one end is closed and the other end is opened so that the element can be adsorbed by a plurality of adsorption apparatuses The adsorption and regeneration operations are alternately performed. Such a device provided a sufficient gas passage area according to the amount of gas throughput, and was able to uniformly flow the regeneration gas in the reverse direction. However, since it is expensive and has a small pore distribution, the influence of the substances causing deterioration of activated carbon such as high- And it is difficult to use them for polluted gas applications including a trace amount of deterioration-causing substances.

On the other hand, an adsorption apparatus using granular activated carbon is usually used to perform adsorption and regeneration operations alternately by using a plurality of adsorption apparatuses as described above. Granular activated carbon is cheap at one-tenth of the cost of fiber-type activated carbon, has the same adsorption capacity, can have various performances such as selective adsorption to specific gas, and can be economically and efficiently The adsorbent has the ability to treat the polluted gas. However, it has the disadvantage that the size of the apparatus is larger than that of the apparatus using the fibrous activated carbon.

On the other hand, there is a method of removing the trace components by using a wet scrubbing column or activated carbon. The wet scrubbing column is operated under high pressure, and then the activated carbon is removed. In order to continuously use the activated carbon scrubbing column, And a regeneration process was separately required in order to regenerate the broken tower after using the adsorption tower. If the adsorption capacity is low even if the regeneration process is performed, a separate adsorption tower for waiting after the regeneration process is also required. In the case of activated carbons with low adsorption capacity, a very large size adsorption tower was required to adsorb all the trace components, which caused the cost of the pressure vessel to increase due to the increase in the size of the pressure vessel in the high pressure process. A method for reducing the size of adsorption tower should be developed for economical high purification process.

Conventional pollutant removal equipment capable of continuously injecting to reduce the size of the adsorption tower determines the adsorption rate depending on the adsorption efficiency obtained through the known experimental values etc. even if the adsorbent adsorption rate is changed according to the influent concentration change. , It is not possible to detect any one of the polluted gases after passing through the adsorption column.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the following examples can be modified in various forms, and the scope of the present invention is not limited to the following examples.

FIG. 1 is a front view and (b) perspective view of a contaminated gas removing apparatus according to an embodiment of the present invention, and FIG. 2 is a cross-sectional perspective view of a pollution gas removing apparatus according to an embodiment of the present invention. FIG. 3 is a cross-sectional view of a pollutant removing device according to an embodiment of the present invention, and FIG. 4 is a view illustrating an adsorption end of the pollutant removing device according to an embodiment of the present invention. .

1 to 4, the apparatus 100 for removing polluting gas according to an embodiment of the present invention includes a body 110 as a pressurizing vessel, a body 110 A syngas discharge unit 112 installed at the upper end of the body 110 for discharging syngas from the body 110, a syngas supply unit 111 installed at the lower end of the body 110 for supplying syngas to the body 110, ), A suction part 120 sloped inside the body part 110 and provided with impregnated activated carbon, a supply part 130 supplying impregnated activated carbon at the upper part of the adsorption part 120, and impregnated activated carbon reacted with the syngas, And a discharge unit 140 for discharging the gas.

The body portion 110 may be, for example, an impregnated activated carbon adsorption tower, and is preferably formed in a cylindrical shape.

A trace amount of contaminant gas such as H ₂ S, COS, HCl, HF, HBr, HCN, and NH _{3 contained in the} syngas flows into the lower portion of the body portion 110, Only the mixed gas adsorbed on the impregnated activated carbon while being reacted with the impregnated activated carbon placed on the adsorbing part 120 installed and removed from the contaminated gas is discharged through the upper part of the body part 110.

4, the adsorption section 120 includes a connection section 124 in which impregnated activated carbon is collected by connecting a pair of swash plates 122 and 123 and a pair of swash plates 122 and 123, The inclined plates 122 and 123 are formed to be inclined downward in the direction of the connecting portion 124. [

The supply unit 130 supplies impregnated activated carbon to the adsorption unit 120 of the body part 110 by a lock hopper system. Since the adsorption unit 120 is formed to be inclined downward toward the discharge unit 140 located on the opposite side of the supply unit 130, the impregnated activated carbon to be supplied is scattered and distributed in a pair of inclined plates 122 and 123 inclined.

The amount of the impregnated activated carbon to be supplied may vary depending on the concentration and the flow rate of the polluted gaseous substance to be adsorbed and the breakthrough time of the impregnated activated carbon, that is, the adsorbent.

For example, when 100 ppm of acid gas is contained in syngas and 100 ppm of acid gas is introduced by the preliminary adsorption capacity evaluation test, 1 kg of impregnated activated carbon is broken after about 1 hour and is no longer adsorbed. 110) can be adsorbed for 100 hours. Accordingly, after 100 hours of adsorption, 100 hours after the start of adsorption, the acidic gases of trace components start to be detected in the synthesis gas passing through the adsorption part 120 of the body part 110 without being adsorbed. Therefore, if replacement is made before 10% breakage, 1.1 kg of fresh impregnated activated carbon is supplied every 1 hour, and 1.1 kg of fresh impregnated carbon per hour is supplied for a total of 110 kg for 100 hours. Only about 90% of the adsorbent 120 is adsorbed and adsorbed on impregnated activated carbon.

The discharge unit 140 may include a storage chamber 160 for storing impregnated activated carbon discharged through a screw, a driving motor for rotating the screw, and a screw provided on the connection portion to transport the impregnated impregnated activated carbon .

The discharge portion 140 may form a drive seal so that the syngas does not leak from the rotating body rotating the screw.

Since the syngas flowing into the body 110, which is a pressurized vessel, flows at a pressure of 20 to 30 bar, the syngas may leak due to the rotating body rotating the screw. Therefore, And the pressure of the nitrogen chamber 150 is maintained to be higher than the pressure of the body 110 by about 1 bar.

That is, a pressure gauge is installed in the nitrogen chamber 150 so that the pressure difference with the body 110 is always maintained at about 1 bar. This is to prevent the synthesis gas from leaking to the outside through the nitrogen chamber with the drive seal. Nitrogen is supplied from time to time in consideration of a pressure difference, which is automatically supplied only by an amount leaked toward the body portion 110 and the motor side through the drive seal.

The driving section sealing is to seal the gas between the rotating body and the fixed nitrogen chamber so that the gas is not leaked to rotate the motor at a predetermined speed to the outside in order to rotate the screw. However, if the seal is completely sealed, it will be difficult to rotate because the resistance of the rotating body is large when it rotates, so that a small clearance is formed. The sealing material is installed at the rotating body so that the leakage amount is minimized, thereby minimizing gas leakage.

On the other hand, the adsorption unit 120 includes at least one adsorption unit, and the adsorption unit is installed on the body unit 110 in an inclined manner.

The adsorption unit 120 can constitute various adsorption stages depending on the kind of the polluted gas. For example, the adsorption unit 120 includes an acidic gas adsorption unit 121 for adsorbing an acidic gas, a basic gas adsorption unit 125 for adsorbing a basic gas, And a neutral gas adsorption stage 126 for adsorbing the gas.

When the synthesis gas and the impregnated activated carbon meet each other, the contaminant gas material contained in the syngas reacts with the metal material on the impregnated activated carbon surface. For example, in the case of acidic gas HCl contained in syngas, the following reaction occurs due to CuO dissolved in the impregnated activated carbon surface.

2HCl (gas) + CuO (solid) -> CuCl ₂ (solid) + H ₂ O (liquid)

Therefore, the HCl contained in the synthesis gas remains as a solid on the surface of the impregnated activated carbon and is adsorbed.

If a plurality of adsorption stages are constructed according to the type of the polluted gas as described above, a feeder 130 for supplying the impregnated activated carbon so as to correspond to the adsorbed carbon one by one and a discharge unit 140 for discharging the impregnated activated carbon should be constructed.

That is, the supply unit 130 includes an acidic gas adsorbent supply unit 131 for supplying the impregnated activated carbon to adsorb the acidic gas at the acidic gas adsorption unit 121, an impregnated activated carbon for adsorbing the basic gas at the basic gas adsorption unit 125, And a neutral gas adsorbent supply unit 133 for supplying an impregnated activated carbon for adsorbing neutral gas at the neutral gas adsorption unit 126. [

The exhaust unit 140 includes an acidic gas adsorbent discharge unit 141 for adsorbing the acidic gas from the acidic gas adsorption unit 121 and discharging the impregnated activated carbon which has passed through it, a basic gas adsorption unit 125 for adsorbing the basic gas And a neutral gas adsorbent discharge unit 143 for discharging the impregnated activated carbon by adsorbing the neutral gas at the basic gas adsorbent discharge unit 142 and the neutral gas absorption stage 126 for discharging the impregnated impregnated activated carbon, Impregnated activated carbon discharged from the acid gas adsorbent discharge unit 141, the basic gas adsorbent discharge unit 142 and the neutral gas adsorbent discharge unit 143 may be stored in the storage chamber 160.

3, the adsorption end is inclined to the body 110 and is inclined downward toward the discharge part 140. The supply part 130 is formed on the opposite side of the discharge part 140, 130, impregnated activated carbon can be uniformly distributed on the inclined adsorption ends by gravity, and the impregnated impregnated activated carbon is collected on the connection part 124 due to the self-inclined structure of the absorption end, And is discharged to the outside by the rotation of the screw, which can be continuously performed during the operation of removing the pollutant gas.

That is, the impregnated activated carbon is continuously supplied through the supply part 130, and the impregnated impregnated activated carbon can be conveyed by the screw and continuously discharged through the discharge part 140.

Accordingly, in order to effectively remove contaminant gas mixed with various components such as H ₂ S, COS, HCl, HF, HBr, HCN, and NH ₃ , various types of impregnated activated carbon, In order to maintain the performance at a constant level, a device capable of filling and removing the adsorbent in a slanted form is provided for each adsorption stage in order to remove the adsorbent which has continuously lost its activity during operation. By using this apparatus, it is possible to effectively reduce the size of the body 110, which is an adsorption tower, which is a pressure vessel, compared to the conventional adsorption tower, and to continuously supply and discharge new adsorbents irrespective of the point of breakage to maintain the performance of the adsorption tower .

In addition, impregnated activated carbon having a capacity of several times to several tens of times higher than that of general activated carbon was used. The adsorption tower was separated into three stages, and an acidic gas adsorbent, a basic gas adsorbent, a neutral gas adsorbent, The concentration of the trace gas in syngas can be reduced to several ppb levels. For continuous adsorption process, new impregnated activated carbon is supplied to the upper part of each adsorption column of the adsorption column by a rock hopper method at a small amount from the upper part, and a small amount of impregnated activated carbon is discharged by a screw method from the bottom, The gas of the component is completely removed and the gas of the minor component is adsorbed at the lower part of the adsorption tower and the adsorbent which is broken at the lower part of the adsorption step is discharged to the outside.

The HSV converting unit 202 converts the image data received from the image data receiving unit 201 into an HSV-dimensional image. More specifically, since the image data received from the image data receiving unit 201 is an RGB (Red, Green, Blue) dimensional image, the HSV converting unit 202 converts HSV (Hue, Saturation, Value) dimensional image. That is, the HSV converter 202 converts RGB image data into HSV image data.

That is, the pollution gas monitoring apparatus 200 determines whether or not the end menu 240 is selected in the screen example shown in FIG. 10, ends the process when the end menu 240 is selected, ) Is not selected, the monitoring proceeds. Alternatively, the monitoring menu 238 may be selected from the driver to proceed with monitoring.

In step S213, the image data receiving unit 201 receives the image data obtained in the image obtaining apparatus 10 in real time / near real time (S214). The received image data is RGB (Red, Green, Blue) dimensional image.

In order to efficiently detect color difference between images, the HSV converter 202 converts the RGB-dimensional image data into HSV-dimensional image data (S215).

The image separator 203 of the detector tube region separates the image data of the transformed HSV image data by the detector tube region (H ₂ S, COS, HCl, HF, HBr, HCN, and NH ₃ ) And creates a star bounding box (S216). 12, for example, an H ₂ S detection tube 12, a COS detection tube 13, an HCl detection tube 14, and a bounding box (not shown) (B0, B1, B2). Among the bounding boxes B0, B1, and B2 shown in FIG. 12, B1 indicates that a color different from B0 and B2 is detected and is distinguished from B0 and B2.

In FIG. 12, only three detector tubes are illustrated by way of example. In the image separator 203 for each detector tube region, a bounding box for the detector tube is created based on the bounding box coordinates determined for each detector tube shown in FIG. 6 (c) can do. As shown in FIG. 8, the bounding box coordinates can be selected by the coordinates of almost the entire area of the detection tube, but a certain area of the detection tube having a color change, for example, an area indicated by dots in B1 in FIG. 8, .

The image segmentation unit 203 according to the detection region image region calculates an average HSV value based on the generated image data in the bounding box for each detection region, that is, the bounding box of the H ₂ S detection region (S217). The average HSV value is an H value obtained by averaging, for example, the H value of the entire region or the predetermined reference, for example, the H value of the selected region or the selected region selected by the random reference, from the image data in the bounding box of the H ₂ S detection tube region . H (Hue) is the color, S (Saturation) is the saturation, and V (value) is the brightness. Although the H value is used in the present embodiment, it may be used in consideration of both the H value, the S value, and the V value.

Specifically, for example, H ₂ S detector tube image within the average HSV values are higher (Upper) HSV of polluted gas by reference reaction color DB (207), see H ₂ S in the reservoir to the reaction color in the H ₂ S Value and a lower HSV value. If it is within the category, it is determined that H ₂ S is detected. If it is not within the category, it is determined that it is not detected (S218).

At this time, if it is determined that H ₂ S is detected, the alarm generating unit 210 transmits the signal to the display unit 209 so that the alarm can be informed to the driver. In addition, the alarm generating unit 207 transmits a signal to the driver's e-mail notifying unit 210 and the driver's SMS notifying unit 211 so that the driver who has left his /

The driver's e-mail notifying unit 210 and the driver's SMS notifying unit 211 transmit the information on the abnormal situation to the driver via e-mail and SMS, respectively (S219).

Prior from step (S217) of calculating the average HSV values in all detector tube images of illustration with H ₂ S is determined (S218) and detects the notification (S219) steps are in addition to _{H 2 S COS, HCl, HF} , HBr, HCN, The same applies to NH ₃ (S220 - S237).

The reaction image or reaction result for each detection tube region acquired by the detection tube region-specific image acquisition unit 207 is transmitted to the image storage unit 205 for each detection tube region and transmitted to the image storage DB 206 in real time / near real time .

In addition, the reaction image for each detection tube region obtained by the detection tube region-specific image acquisition unit 207 and the determination result derived from the image comparison determination unit 208 are transmitted to the display unit 209. Accordingly, the driver can know the reaction state of each detection tube region in real time / near real time.

The display unit 209 has a function of executing a monitoring menu 238, a configuration menu 239 and a termination menu 240 as shown in FIG. 10, and displays H ₂ S, COS, HCl, HF , HBr, HCN, and NH ₃ are displayed in real time / near real time through bar bars 241 to 247 for each detection tube region so that the current color of the detection tube can be known. In addition, the monitoring notification window 248 informs the driver of the start and end of monitoring and whether or not the detection of each of the pollution gases is performed whenever an event occurs.

If the pollution gas monitoring apparatus 200 detects pollution gas from at least one of the plurality of detection tubes as a result of the determination by the image comparison determination unit 208, The supply amount to be supplied to the adsorption tower, here the adsorption unit 110, is controlled so as to increase the supply amount of the adsorbent supplied to the gas removal apparatus 100.

Particularly, in order to effectively remove contaminant gas mixed with various components such as H ₂ S, COS, HCl, HF, HBr, HCN, and NH ₃ , impregnated gas removing apparatus 100 may include various kinds of impregnated activated carbon, In order to maintain the adsorption performance at a constant level, a device capable of filling and removing the adsorbent in an oblique shape is provided for each adsorption stage in order to remove the adsorbent which has been continuously lost during operation.

As described above, when a color change occurs, for example, in the HCN detection tube to the gas exhausted through the pollutant removal device 100, the pollutant gas monitoring and monitoring device 200 detects the presence of the acidic gas adsorbent The acid gas adsorbent supply unit 131 is controlled so as to increase the existing supply amount (10 kg / day) supplied from the supply unit 131 to a predetermined supply amount (for example, 15 kg / day) by experience. Thus, the performance of the adsorption tower is prevented from being lowered, and uniform performance can be obtained at all times.

If a small amount of contaminant gas that has not been removed from the pollutant gas removal device 100 through the above-described pollutant gas monitoring device 200 is damaged, the expensive fuel cell is damaged. Therefore, It is preferable to detect the presence of the polluted gas in the gas and increase the amount of the adsorbent immediately if the polluted gas remains, so that the entire process is automatically maintained so that the polluted gas is not detected again.

In particular, whether the polluted gas remains in the gas discharged from the pollutant-gas removing apparatus 100 that effectively removes various trace components contained in the syngas is immediately informed of the abnormal change of the detector tube through the color change of the detector tube, It is more preferable that the supply amount of the new adsorbent is automatically increased in the control chamber so as to be increased beyond the existing supply amount.

11, a monitoring menu 301, an environment 300, and an environment 300 are connected to the pollution gas monitoring apparatus 200, A setting menu 302, and a termination menu 303. [

The pollution gas monitoring and managing apparatus 300 may be connected to the image capturing apparatus 10 and the pollution gas monitoring apparatus 200 in a communicable manner according to a wireless communication scheme. Accordingly, the driver can monitor whether or not the polluted gas remains in the gas discharged from the polluted gas removing apparatus 100 at any time from a remote place through the polluted gas monitoring condition managing apparatus 300. [ Further, the IP address of the image acquisition device 10 and the pollution gas monitoring device 200 can be set.

The invention being thus described, it will be obvious that the same way may be varied in many ways. Such modifications are intended to be within the spirit and scope of the invention as defined by the appended claims.
