Description

The present disclosure relates to carbonation monitoring systems.

BACKGROUND ART A technique is known in which alkaline solid reactants such as incineration ash generated when waste such as industrial waste is incinerated are carbonated by aeration treatment using a gas containing carbon dioxide (CO ₂ ).

(First embodiment)
First, the carbonation monitoring system 1 of the first embodiment will be described. FIG. 1 is a schematic diagram showing a carbonation monitoring system 1 according to the first embodiment. The carbonation monitoring system 1 includes a processing device 10, a supply device 50, a measuring device 60, an electromagnetic valve V1, and a control device 90.

The processing device 10 is connected to a supply device 50 via a supply line L1. The supply line L1 is provided with an electromagnetic valve V1 that adjusts the amount of gas G supplied from the supply device 50 to the processing device 10. The processing device 10 receives the gas G supplied from the supply device 50 from the supply line L1 when the electromagnetic valve V1 is open. The container body 11 of the processing apparatus 10 has a box shape with a side wall and a bottom, and is open at the top. The wall portion of the container body 11 is made of metal such as an iron plate, steel, or stainless steel, for example. The container body 11 is covered with a lid 40 while the object to be treated 100 is being carbonated. In addition, in the processing apparatus 10, while the object to be treated 100 is being carbonated, instead of the container body 11 being covered with the lid 40, a sheet 42 or the like as shown in FIG. It may be covered to cover. The processing device 10 includes a first chamber 12, a second chamber 14, a partition wall 16, and an air supply port 20.

The first chamber 12 receives gas G from the supply line L1 via the air supply port 20. The first chamber 12 is filled with gas G. The first chamber 12 is provided below the second chamber 14 with a partition wall 16 in between. The second chamber 14 stores the object 100 to be processed. The second chamber 14 is provided above the first chamber 12 with a partition wall 16 in between. The first chamber 12 and the second chamber 14 are ventilable. Gas G is sent to the second chamber 14 from the first chamber 12 via the partition wall 16 at the lower part.

The partition wall 16 is a plate material that separates the first chamber 12 and the second chamber 14 from each other. The partition wall 16 is provided at a distance from the bottom of the container body 11. The object to be processed 100 is placed on the partition wall 16 . The partition wall 16 has at least air permeability. The partition wall 16 includes a plurality of holes 18 in the first embodiment. Gas G can move between the first chamber 12 and the second chamber 14 through the plurality of holes 18 . For example, the plurality of holes 18 are arranged at predetermined intervals along the side wall portion of the container body 11. The partition wall 16 is formed, for example, by punching a plurality of holes 18 in a metal plate. The number and position of the holes 18 are not particularly limited as long as the partition wall 16 has air permeability. The partition wall 16 may have a mesh structure, for example. The partition wall 16 may be a single plate material or may be a plurality of laminated plate materials.

The processing device 10 allows gas G to pass from the first chamber 12 to the second chamber 14 . That is, the processing apparatus 10 performs a carbonation reaction between the workpiece 100 and the gas G by aerating the gas G containing carbon dioxide through the workpiece 100 containing the alkaline solid reactant stored in the second chamber 14. let For example, when the alkaline solid reactant is incineration ash, the incineration ash is carbonated so that the heavy metals contained therein, such as calcium and lead, become difficult to dissolve. After the carbonation reaction, the gas G has a reduced carbon dioxide content. That is, the carbon dioxide concentration of the gas G that has passed through the object to be treated 100 is approximately 0% immediately after the start of the treatment, increases as the treatment progresses, and reaches approximately the same concentration as the supplied gas G at the end of the treatment.

The supply device 50 includes a gas G supply source. The supply device 50 supplies the gas G to the processing device 10 via the supply line L1. In the first embodiment, the supply device 50 is a cylinder in which liquefied carbon dioxide gas as the gas G to be supplied is stored. The gas G supplied from the supply device 50 is assumed to be a highly purified liquefied carbon dioxide gas with a carbon dioxide concentration of 99.99% or more, which can be purchased in the form of a cylinder or the like.

The measuring device 60 measures the carbon dioxide concentration of the gas G after the carbonation reaction in the second chamber 14 of the processing device 10 . The measuring device 60 is provided inside the second chamber 14 in the first embodiment. The measuring device 60 includes a detection section 62 such as a probe, and a housing 64. The detection unit 62 detects carbon dioxide concentration. The housing 64 accommodates the detection unit 62. The housing 64 has an opening on the bottom surface. In the first embodiment, the housing 64 has an umbrella shape that covers the sides and top of the detection unit 62. Since it is preferable that the temperature difference between the inside of the casing 64 and the inside of the second chamber 14 is small, the casing 64 may include a heating element that heats the inside of the casing 64.

The electromagnetic valve V1 is provided in the supply line L1 that connects the supply device 50 and the processing device 10. The electromagnetic valve V1 receives a valve control signal Sv1 from the control device 90. The electromagnetic valve V1 adjusts the amount of gas G supplied from the supply device 50 to the processing device 10 based on the valve control signal Sv1 received from the control device 90. For example, when the electromagnetic valve V1 receives a valve control signal Sv1 indicating to start supplying the gas G from the control device 90, the electromagnetic valve V1 is adjusted so as to open the valve and supply the gas G to the processing device 10. For example, when the electromagnetic valve V1 receives a valve control signal Sv1 indicating a reduction in the amount of gas G supplied from the control device 90, the solenoid valve V1 throttles the valve to reduce the amount of gas G supplied to the processing device 10. adjust. For example, when the electromagnetic valve V1 receives a valve control signal Sv1 indicating that the supply of gas G is to be stopped from the control device 90, the electromagnetic valve V1 is adjusted to close the valve and stop the supply of the gas G to the processing device 10. .

The control device 90 controls the processing by the carbonation monitoring system 1. The control device 90 acquires a concentration value information signal Vg that is carbon dioxide concentration information detected by the detection unit 62 of the measurement device 60. The control device 90 obtains the concentration value information signal Vg at a predetermined period, for example. The control device 90 outputs a valve control signal Sv1 that controls the electromagnetic valve V1 based on the acquired concentration value information signal Vg.

That is, the control device 90 controls the electromagnetic valve V1 to adjust the amount of gas G supplied to the first chamber 12 of the processing device 10 according to the carbon dioxide concentration of the gas G measured by the measuring device 60. . More specifically, the control device 90 controls the electromagnetic valve V1 to change the amount of gas G supplied from the supply device 50 to the processing device 10 based on the information acquired from the measurement device 60. The control device 90 may store in advance a suitable amount of the gas G to be supplied corresponding to the measured carbon dioxide concentration of the gas G, for example. In this case, the control device 90 controls the electromagnetic valve V1 so that the supply amount of the gas G is a suitable supply amount.

As described above, the carbonation monitoring system 1 of the first embodiment includes the processing device 10, the measuring device 60, the electromagnetic valve V1 (first electromagnetic valve), and the control device 90. The processing device 10 causes a carbonation reaction between the object to be processed 100 (alkaline solid reactant) and the gas G containing carbon dioxide. The measuring device 60 measures the carbon dioxide concentration of the gas G after the carbonation reaction.
The electromagnetic valve V1 can adjust the amount of gas G supplied from the supply device 50 (supply source) to the processing device 10. The control device 90 controls the electromagnetic valve V1 to change the amount of gas G supplied from the supply device 50 based on the information acquired from the measurement device 60.

The carbon dioxide concentration measured immediately after the start of the treatment is approximately 0% because almost all of the carbon dioxide contained in the gas G is used for the carbonation reaction with the object to be treated 100. On the other hand, as the carbonation of the object 100 progresses, the carbonation reaction slows down and the amount of carbon dioxide used decreases, so the measured carbon dioxide concentration increases. An increase in carbon dioxide concentration indicates that the amount of gas G supplied is excessive. The carbonation monitoring system 1 of the first embodiment can suppress wastage of the gas G by adjusting the supply amount of the gas G based on the measured value of the carbon dioxide concentration of the gas G. Therefore, the total amount of gas G to be supplied for use in the carbonation reaction can be optimized. Since the carbonation monitoring system 1 adjusts the supply amount based on the concentration of carbon dioxide itself in the gas G used for the carbonation reaction, it is possible to suppress the influence of the environment such as outside temperature. By optimizing the total supply amount of gas G, it is possible to contribute to cost reduction.

In the carbonation monitoring system 1, the measuring device 60 is provided inside the processing device 10, and a detection unit 62 for detecting carbon dioxide concentration is provided inside a casing 64 having an opening at the bottom. Since the carbonation reaction is an exothermic reaction, water droplets generated by condensation may fall from the top if the wall of the container body 11 or the container body 11 is covered with a lid, sheet, or the like. In the carbonation monitoring system 1, by covering the upper part of the detection section 62 with the casing 64, it is possible to suppress water droplets from adhering to the detection section 62, thereby preventing deterioration of the detection section 62.

In the carbonation monitoring system 1 , the measuring device 60 has a heating element that warms or heats the inside of the housing 64 . Since dew condensation is caused by temperature differences, even if there is a sudden temperature rise in the container body 11, the occurrence can be suppressed by heating the inside of the casing 64.

(Second embodiment)
Next, a carbonation monitoring system 2 according to a second embodiment will be explained. FIG. 2 is a schematic diagram showing a carbonation monitoring system 2 according to a second embodiment. The carbonation monitoring system 2 includes a processing device 10, a supply device 50, a measuring device 60A, a suction pump 70, a dehumidifying device 80, an electromagnetic valve V1, and a control device 90A. In addition, in the carbonation monitoring system 2 of the second embodiment, the same components as those of the carbonation monitoring system 1 of the first embodiment are given the same reference numerals, and the explanation will be omitted as appropriate, and the different components will be explained.

The measuring device 60A is provided inside the second chamber 14 in the second embodiment. Compared to the measuring device 60 of the first embodiment, the measuring device 60A of the second embodiment has an umbrella-shaped casing 64 that covers the sides and top of the detecting section 62; The difference is that it includes a housing 68 that covers the upper and lower sides and has airtightness. The housing 68 is connected to the suction pump 70 via the air supply line L2. The measuring device 60A measures the carbon dioxide concentration of the gas G taken in from the second chamber 14 of the processing device 10 by the suction pump 70 and subjected to a carbonation reaction.

The suction pump 70 is provided inside the second chamber 14 in the second embodiment. The suction pump 70 draws in the gas G after the carbonation reaction from inside the second chamber 14 of the processing device 10 . The suction pump 70 sends out the taken-in gas G to the air supply line L2. The suction pump 70 receives the pump drive signal Sp1 from the control device 90A. The suction pump 70 suctions the gas G based on the pump drive signal Sp1 received from the control device 90A. The suction pump 70 may be constantly driven while the processing device 10 is in operation.

The dehumidifier 80 is provided in the air supply line L2 that connects the measuring device 60A and the suction pump 70. The dehumidifier 80 dehumidifies the gas G taken in by the suction pump 70. The dehumidifier 80 includes, for example, a heat exchanger such as a radiator. The dehumidifier 80 dehumidifies the gas G by, for example, cooling the gas G and removing generated water droplets. The gas G dehumidified by the dehumidifier 80 is sent to the measuring device 60A. The dehumidification device 80 receives the dehumidification drive signal Sd from the control device 90A. The dehumidifier 80 dehumidifies the gas G based on the dehumidification drive signal Sd received from the control device 90A. The dehumidifying device 80 may be constantly driven while the processing device 10 is in operation.

The control device 90A controls the processing by the carbonation monitoring system 2. The control device 90A acquires a concentration value information signal Vg that is carbon dioxide concentration information detected by the detection unit 62 of the measurement device 60A. The control device 90A obtains the concentration value information signal Vg at a predetermined period, for example. The control device 90A outputs a pump drive signal Sp1 that controls the suction pump 70 and a dehumidification drive signal Sd that controls the dehumidification device 80. The control device 90A may drive the suction pump 70 and the dehumidifier 80 only when measuring with the measuring device 60A. In this case, the control device 90A acquires the concentration value information signal Vg at the timing when the gas G is taken into the measuring device 60A.

The control device 90A outputs a valve control signal Sv1 that controls the electromagnetic valve V1 based on the acquired concentration value information signal Vg. That is, the control device 90A controls the electromagnetic valve V1 to adjust the amount of gas G supplied to the first chamber 12 of the processing device 10 according to the measured carbon dioxide concentration of the gas G. More specifically, the control device 90A controls the electromagnetic valve V1 to change the amount of gas G supplied from the supply device 50 to the processing device 10 based on the information acquired from the measurement device 60A. The control device 90A may store in advance a suitable amount of the gas G to be supplied corresponding to the measured carbon dioxide concentration of the gas G, for example. In this case, the control device 90A controls the electromagnetic valve V1 so that the amount of gas G supplied is a suitable amount.

As described above, the carbonation monitoring system 2 of the second embodiment further includes the suction pump 70 (first suction pump) that sends the gas G after the carbonation reaction inside the processing device 10 to the measuring device 60A. The measuring device 60A is provided with a detection unit 62 that detects carbon dioxide concentration inside an airtight casing 68.

Air flows inside the container body 11 due to heat generated by the carbonation reaction, and outside air may flow in from the upper opening. The carbonation monitoring system 2 of the second embodiment can collect the gas G from a location where the carbon dioxide concentration is desired to be measured by actively sucking the gas G after the carbonation reaction using the suction pump 70. That is, since the carbonation monitoring system 2 can adjust the sampling point of the gas G, it can actively collect the gas G after the carbonation reaction with the object 100 to be treated.

The carbonation monitoring system 2 further includes a dehumidifier 80 that dehumidifies the gas G sent from the suction pump 70 (first suction pump) to the measuring device 60A. The suction pump 70 is provided inside the processing device 10 . As a result, the humidity of the gas G taken into the measuring device 60A can be reduced, so that it is possible to suppress the occurrence of an error in the measured value of carbon dioxide concentration due to water droplets adhering to the detection unit 62.

In the carbonation monitoring system 2, the control device 90A drives the suction pump 70 (first suction pump) only when measuring with the measuring device 60A. That is, the measurement of the carbon dioxide concentration of the gas G after the carbonation reaction does not have to be carried out all the time, and may be carried out at predetermined intervals, for example. The gas G drawn into the measuring device 60A is normally released to the outside air. Further, in the gas G remaining in the processing device 10 after the carbonation reaction, the remaining carbon dioxide undergoes a carbonation reaction with the object to be processed 100 on the surface side. By providing a stop time for suction and measurement of gas G, waste of gas G can be suppressed.

(Third embodiment)
Next, a carbonation monitoring system 3 according to a third embodiment will be explained. FIG. 3 is a schematic diagram showing a carbonation monitoring system 3 according to a third embodiment. The carbonation monitoring system 3 includes a processing device 10A, a supply device 50, a measuring device 60B, a suction pump 70A, an electromagnetic valve V1, and a control device 90B. In addition, in the carbonation monitoring system 3 of the third embodiment, the same components as those of the carbonation monitoring system 2 of the second embodiment are given the same reference numerals, and the explanation will be omitted as appropriate, and the different components will be explained.

The processing device 10A of the third embodiment is different from the processing device 10 of the second embodiment in that it further includes an intake port 22. The intake port 22 is provided in the second chamber 14 . In the third embodiment, the intake port 22 is provided on the side wall of the container body 11 above the object to be processed 100. The second chamber 14 is connected to the intake line L31 via the intake port 22 in the third embodiment.

The measuring device 60B of the third embodiment is different from the measuring device 60A of the second embodiment in that it is provided outside the processing device 10A instead of inside the second chamber 14. The housing 68 of the measuring device 60B is connected to the suction pump 70A via an air supply line L32. The measuring device 60B measures the carbon dioxide concentration of the gas G taken in from the second chamber 14 of the processing device 10A by the suction pump 70A and subjected to a carbonation reaction.

The suction pump 70A of the third embodiment is different from the suction pump 70 of the second embodiment in that it is provided outside the processing device 10A instead of inside the second chamber 14. The suction pump 70A draws in the gas G after the carbonation reaction from the second chamber 14 of the processing device 10A via the intake line L31. The suction pump 70A sends out the taken-in gas G to the air supply line L32. Suction pump 70A receives pump drive signal Sp1 from control device 90B. The suction pump 70A is driven to transfer gas from the intake line L31 side to the air supply line L32 side based on the pump drive signal Sp1 received from the control device 90B. The suction pump 70A may be constantly driven while the processing device 10A is in operation.

A desiccant is provided in at least one of the intake line L31 and the air supply line L32. Thereby, the gas G after the carbonation reaction is dehumidified before being sent to the measuring device 60B. In the carbonation monitoring system 3 of the third embodiment, the dehumidifier 80 of the second embodiment may be provided in the air supply line L32 instead of providing a desiccant.

The control device 90B controls the processing by the carbonation monitoring system 3. The control device 90B acquires a concentration value information signal Vg that is carbon dioxide concentration information detected by the detection unit 62 of the measurement device 60B. The control device 90B obtains the concentration value information signal Vg at a predetermined period, for example. The control device 90B outputs a pump drive signal Sp1 that controls the suction pump 70A. The control device 90B may drive the suction pump 70A only when measuring with the measuring device 60B. In this case, the control device 90B acquires the concentration value information signal Vg at the timing when the gas G is taken into the measuring device 60B.

The control device 90B outputs a valve control signal Sv1 that controls the electromagnetic valve V1 based on the acquired concentration value information signal Vg. That is, the control device 90B controls the electromagnetic valve V1 to adjust the amount of gas G supplied to the first chamber 12 of the processing device 10A according to the measured carbon dioxide concentration of the gas G. More specifically, the control device 90B controls the electromagnetic valve V1 to change the amount of gas G supplied from the supply device 50 to the processing device 10A based on the information acquired from the measurement device 60B. For example, the control device 90B may store in advance a suitable amount of the gas G to be supplied corresponding to the measured carbon dioxide concentration of the gas G. In this case, the control device 90B controls the electromagnetic valve V1 so that the amount of gas G supplied is a suitable amount.

As explained above, in the carbonation monitoring system 3 of the third embodiment, the measuring device 60B and the suction pump 70A (first suction pump) are provided outside the processing device 10A.

It is assumed that the processing apparatus 10A carries in and out the object to be processed 100 from the upper part of the container body 11. In the carbonation monitoring system 3 of the third embodiment, by providing the measuring device 60B and the suction pump 70A outside the processing device 10A, it is possible to prevent the measurement device 60B and the suction pump 70A from interfering with the loading and unloading of the processed material 100. Further, it is easy to provide a dehumidifying means for reducing the humidity of the gas G in the path from the suction pump 70A to the measuring device 60B.

In the carbonation monitoring system 3, the suction pump 70A (first suction pump) sucks the gas G after the carbonation reaction from above the object to be treated 100 (alkaline solid reactant) of the processing device 10A. Since the gas G after the carbonation reaction escapes above the container body 11, by actively sucking the gas G from near the upper side wall of the object to be processed 100, the carbonation reaction with the object to be processed 100 is completed. The subsequent gas G can be actively collected.

(Fourth embodiment)
Next, a carbonation monitoring system 4 according to a fourth embodiment will be described. FIG. 4 is a schematic diagram showing a carbonation monitoring system 4 according to the fourth embodiment. The carbonation monitoring system 4 includes a processing device 10B, a supply device 50, a measuring device 60B, a suction pump 70A, a suction pump 70B, an electromagnetic valve V1, and a control device 90C. In addition, in the carbonation monitoring system 4 of the fourth embodiment, the same configurations as those of the carbonation monitoring system 3 of the third embodiment are given the same reference numerals, and the explanation will be omitted as appropriate, and different configurations will be explained.

The processing device 10B of the fourth embodiment is different from the processing device 10A of the third embodiment in that it further includes an air supply port 24 and an air intake port 26. The air supply port 24 is provided in the first chamber 12 . The first chamber 12 is connected to the air supply line L42 via the air supply port 24 in the fourth embodiment. The intake port 26 is provided in the second chamber 14 . The second chamber 14 is connected to the intake line L41 via the intake port 26 in the fourth embodiment.

The suction pump 70B is provided outside the processing device 10B. The suction pump 70B draws in the gas G after the carbonation reaction from the second chamber 14 of the processing device 10B via the intake line L41. The suction pump 70B sends out the taken-in gas G to the air supply line L42. Suction pump 70B receives pump drive signal Sp2 from control device 90C. The suction pump 70B is driven to transfer gas from the intake line L41 side to the air supply line L42 side based on the pump drive signal Sp2 received from the control device 90C. That is, the suction pump 70B sucks the gas G after the carbonic acid reaction from the second chamber 14 and supplies it to the first chamber 12 again. Thereby, the gas G circulates between the first chamber 12 and the second chamber 14.

A desiccant is provided in at least one of the intake line L41 and the air supply line L42. Thereby, the gas G after the carbonation reaction is dehumidified before being sent to the suction pump 70B or the second chamber 14.

The suction pump 70B sends out the taken-in gas G to the air supply line L42. Suction pump 70B receives pump drive signal Sp2 from control device 90D. The suction pump 70B is driven to transfer gas from the intake line L41 side to the air supply line L42 side based on the pump drive signal Sp2 received from the control device 90D.

(Sixth embodiment)
Next, a carbonation monitoring system 6 according to a sixth embodiment will be explained. FIG. 6 is a schematic diagram showing a carbonation monitoring system 6 according to the sixth embodiment. The carbonation monitoring system 6 includes a processing device 10D, a supply device 50, a measuring device 60B, a suction pump 70A, an electromagnetic valve V1, an electromagnetic valve V2, and a control device 90E. In addition, in the carbonation monitoring system 6 of the sixth embodiment, the same components as those of the carbonation monitoring system 3 of the third embodiment are given the same reference numerals, and the explanation will be omitted as appropriate, and the different components will be explained.

The processing device 10D of the sixth embodiment is different from the processing device 10A of the third embodiment in that it further includes an air supply port 24. The air supply port 24 is provided in the first chamber 12 . The first chamber 12 is connected to the air supply line L5 via the air supply port 24 in the sixth embodiment. One end of the air supply line L5 communicates with the air supply line L32. The other end of the air supply line L5 communicates with the air supply port 24 of the first chamber 12. The air supply line L5 is provided with an electromagnetic valve V2 that opens and closes between the suction pump 70A and the air supply port 24.

The electromagnetic valve V2 is provided in the air supply line L5 that connects the air supply line L32 and the first chamber 12 of the processing device 10D. The electromagnetic valve V2 receives the valve control signal Sv2 from the control device 90E. The electromagnetic valve V2 adjusts whether or not to circulate the gas G between the first chamber 12 and the second chamber 14 based on the valve control signal Sv2 received from the control device 90E. For example, when the electromagnetic valve V2 receives a valve control signal Sv2 indicating that the circulation of the gas G is to be started from the control device 90E, the electromagnetic valve V2 opens the valve to circulate the gas G between the first chamber 12 and the second chamber 14. Adjust to circulate.

The electromagnetic valve V2 may adjust the supply amount of the gas G to be circulated between the first chamber 12 and the second chamber 14 based on the valve control signal Sv2 received from the control device 90E. The suction pump 70A may include an inverter, for example. For example, the amount of circulation can be adjusted by controlling the power supplied to the suction pump 70A by a control device 90E, which will be described later. Further, the intake line L31 may include a damper, for example. A control device 90E, which will be described later, controls the damper to adjust the amount of circulation.
For example, when the electromagnetic valve V2 receives a valve control signal Sv2 indicating that the amount of gas G to be circulated is increased from the control device 90E, the electromagnetic valve V2 further opens the valve and causes the gas G to circulate between the first chamber 12 and the second chamber 14.

The control device 90E controls the processing by the carbonation monitoring system 6. The control device 90E acquires a concentration value information signal Vg that is carbon dioxide concentration information detected by the detection unit 62 of the measurement device 60B. The control device 90E obtains the concentration value information signal Vg at a predetermined period, for example. The control device 90E outputs a pump drive signal Sp1 that controls the suction pump 70A. The control device 90E may drive the suction pump 70A only when measuring with the measuring device 60B. In this case, the control device 90E acquires the concentration value information signal Vg at the timing when the gas G is taken into the measuring device 60B.

The control device 90E outputs a valve control signal Sv1 that controls the electromagnetic valve V1 and a valve control signal Sv2 that controls the electromagnetic valve V2 based on the acquired concentration value information signal Vg. That is, the control device 90E controls the electromagnetic valve V1 to adjust the supply amount of the gas G supplied from the supply device 50 to the first chamber 12 of the processing device 10D according to the measured carbon dioxide concentration of the gas G. . More specifically, the control device 90E controls the electromagnetic valve V1 to change the amount of gas G supplied from the supply device 50 to the processing device 10D based on the information acquired from the measurement device 60B. Further, the control device 90E controls the electromagnetic valve V2 so that the gas G circulates between the first chamber 12 and the second chamber 14 according to the measured carbon dioxide concentration of the gas G.

As explained above, the carbonation monitoring system 6 of the sixth embodiment is configured to supply gas G to be re-supplied to the processing device 10D from among the gas G sent from the suction pump 70A (first suction pump) to the measuring device 60B. It further includes a solenoid valve V2 (second solenoid valve) whose amount can be adjusted. The control device 90E controls the electromagnetic valve V2 to circulate the gas G inside the processing device 10D based on the information acquired from the measuring device 60B.

As the carbonation of the object 100 progresses, the carbonation reaction slows down and the amount of carbon dioxide used decreases. The carbonation monitoring system 6 of the sixth embodiment recycles the gas G that still contains carbon dioxide after the carbonation reaction by circulating the gas G based on the measured value of the carbon dioxide concentration of the gas G. Can be done. This makes it possible to suppress the waste of the gas G having a high carbon dioxide content supplied from the supply device 50, so that the total supply amount of the gas G used for the carbonation reaction can be optimized. Moreover, since a part of the gas G sent to the measuring device 60B is circulated, the carbon dioxide concentration of the gas G returned to the processing device 10D is approximately equal to the carbon dioxide concentration measured by the measuring device 60B. Therefore, the usefulness of the reused gas G can be ensured.

The carbonation monitoring system 6 of the sixth embodiment circulates the gas G sucked into the suction pump 70A provided outside the processing device 10D, but unlike the second embodiment, the carbonation monitoring system 6 is provided inside the processing device 10. The gas G sucked by the suction pump 70 may be circulated to the first chamber 12.

In addition, by adjusting the circulation amount of gas G, even if the carbon dioxide concentration of the gas G to be circulated fluctuates, the amount of carbon dioxide supplied per hour can be kept constant, so the carbonation reaction can be maintained. It can be stabilized. Alternatively, the carbonation reaction can be promoted by reducing the circulation amount of gas G and lowering the wind speed in accordance with the decrease in the carbon dioxide concentration within the processing device 10D.
