In the first treatment state, the exhaust gas to be treated passes through the first heat storage chamber and is supplied into the combustion chamber from the supply passage, and the components in the exhaust gas are decomposed by the high temperature oxidation treatment in the combustion burner provided in the combustion chamber. The treated exhaust gas passes through the second heat storage chamber and is discharged to the discharge passage. Here, the control of the combustion amount by the combustion burner is adjusted by the combustion control means so that the temperature in the combustion chamber detected by the temperature sensor provided in the combustion chamber falls within a predetermined set temperature range. The set temperature range is set based on the oxidative decomposition temperature of the component to be treated and the heat resistant temperature of the combustion chamber. When the exhaust gas subjected to the high-temperature oxidation treatment passes through the second heat storage chamber, the heat of the exhaust gas is stored in the heat storage material of the second heat storage chamber by heat exchange. Further, when the exhaust gas from the supply path passes through the first heat storage chamber, it is preheated by the stored heat of the exhaust gas stored in the heat storage material of the first heat storage chamber in the second processing state immediately before and is supplied to the combustion chamber. . In the second processing state, processing and phenomena opposite to those in the first processing state occur. Therefore, by alternately repeating the first and second treatment states, the retained heat of the exhaust gas subjected to the high temperature oxidation treatment is utilized for preheating the exhaust gas sequentially supplied from the supply path, so that the high temperature in the combustion chamber is increased. The energy consumption required for the oxidation treatment can be reduced, and the thermal efficiency can be improved.

Since it is also applicable to the third heat storage chamber, the heat of the exhaust gas subjected to the high temperature oxidation treatment is preheated one after another by repeating the respective processing states in sequence by the switching operation of the communication switching means.

Exhaust heat generated in the heat storage type exhaust gas treatment device is
It has been conventionally practiced to provide a heat exchanger in the discharge path and to take it out, but if this is done, heat is once exchanged in the heat storage chamber and the temperature drops, and the load on the heat exchanger (the amount of recovered heat energy consumed) is reduced. Even if the amount of combustion in the combustion chamber is changed when it fluctuates, there is a disadvantage that the response delays considerably, and the exhaust gas temperature in the exhaust passage fluctuates due to changes in the processing state by the communication switching means. . Therefore, an exhaust heat recovery apparatus has been proposed (see, for example, Japanese Patent No. 3095531) that directly uses the exhaust heat of the exhaust gas subjected to the high temperature oxidation treatment in the combustion chamber, and is put into practical use.

Therefore, when the load on the heat exchanger is reduced while the amount of exhaust gas supplied to the heat exchanger is constant, the temperature (or pressure) of the heat medium in the heat exchanger rises, so that the sensor detects the heat medium. The opening of the damper is adjusted by the temperature (or pressure), the amount of exhaust gas supplied to the heat exchanger decreases,
The amount of exhaust gas discharged from the combustion chamber through the heat storage chamber increases. As a result, the heat energy stored in the heat storage chamber increases, and the temperature of the exhaust gas passing through the heat storage chamber and supplied to the combustion chamber rises in the next processing state. Here, the temperature detected by the temperature sensor provided in the combustion chamber becomes high, and the combustion control means adjusts the amount of fuel and air supplied to the combustion burner to reduce the combustion amount, thus suppressing the temperature rise in the combustion chamber. To be done. However, when the exhaust gas to be treated contains a combustible component such as an organic solvent, this combustible component is preheated in the heat storage chamber, and if heated above the ignition temperature of the combustible component, it will self-combust and generate thermal energy. When the heat energy generated by the combustible component is large, the temperature increase in the combustion chamber cannot be suppressed only by adjusting the combustion amount by the combustion burner, and the combustion chamber temperature continues to increase. There is also a risk of inducing an abnormal temperature rise in which the combustion chamber temperature reaches or exceeds the heat resistant temperature of the combustion chamber or the like.

The operation and effect of the above characteristic structure will be described below.

Hereinafter, the case where the second gas discharge amount is adjusted based on the detection amount of the first sensor and the case where it is adjusted based on the detection amount of the second sensor will be described separately. In the former case,
Since both the first gas discharge amount and the second gas discharge amount are adjusted based on the detection amount of the first sensor, the control algorithm can be simplified. That is, when the load of the heat exchanger decreases, the temperature (or pressure) of the heat medium of the heat exchanger rises, and as the detected value of the first sensor rises, the first gas discharge amount supplied to the heat exchanger. The amount of exhaust gas discharged through the heat storage chamber is kept constant by increasing the amount of the second gas discharge by the amount of decrease in the heat storage chamber. Since this is not done, it is possible to prevent the temperature in the combustion chamber from fluctuating with load changes in the heat exchanger, and as a result, it is possible to avoid an abnormal temperature rise. Also, the first
Due to the reduction of the gas discharge amount, the rise of the heat medium temperature (or pressure) is suppressed, and the stable exhaust heat recovery can be maintained.

Therefore, in the former case, when the control temperature in the combustion chamber is set below the ignition temperature of the combustible component contained in the exhaust gas, or even when the control temperature is above the ignition temperature, the thermal energy of the combustible component generated Even if there is a fluctuation, the temperature inside the combustion chamber can be stably controlled even if the load on the heat exchanger is reduced in the state where the temperature fluctuation inside the combustion chamber due to the fluctuation can be absorbed by adjusting the combustion amount in the combustion chamber.

In the latter case, when the load on the heat exchanger decreases, the temperature (or pressure) of the heat medium of the heat exchanger rises, and the detected value of the first sensor rises, so The supplied first gas discharge amount decreases, the exhaust gas amount temporarily discharged through the heat storage chamber increases, and the temperature in the combustion chamber rises. Since the second sensor detects this temperature rise,
By increasing the second gas discharge amount based on the detection value of the second sensor, the amount of exhaust gas discharged through the temporarily increased heat storage chamber is reduced to the original state, and the temperature in the combustion chamber rises. Is suppressed. As a result, it is possible to prevent the temperature in the combustion chamber from fluctuating with the load change of the heat exchanger, and as a result, it is possible to avoid an abnormal temperature rise. Further, the decrease of the first gas discharge amount suppresses the rise of the heat medium temperature (or pressure), and the stable exhaust heat recovery can be maintained.

Further, in the latter case, since the second gas discharge amount is directly adjusted based on the detection value of the second sensor, the amount of combustible components in the exhaust gas supplied to the combustion chamber increases, and Even if the temperature rise due to the combustion of the combustible component exceeds the absorbable range due to the adjustment of the combustion amount, it is possible to suppress the temperature rise in the combustion chamber by increasing the second gas discharge amount.

In the latter case, the temperature inside the combustion chamber slightly rises even temporarily, so the former and the latter are combined to make the second gas emission amount the detection amount of the first sensor and the second sensor. By making adjustments based on this, more stable adjustment of the combustion chamber temperature becomes possible.

According to the second characteristic constitution of the heat storage type exhaust gas treatment apparatus or the control method of the heat storage type exhaust gas treatment apparatus, in the case where the exhaust gas to be treated contains a combustible component such as an organic solvent, the heat exchanger. Even if the load decreases, the abnormal temperature rise in the combustion chamber can be prevented by adjusting the amount of exhaust gas discharged from the combustion chamber via the second bypass path without passing through the heat storage chamber. That is, the same effect as that of the first characteristic configuration can be obtained.

Specifically, when the load on the heat exchanger is reduced,
As the heat medium temperature (or pressure) of the heat exchanger rises and the detection value of the first sensor rises, the second gas discharge amount is increased, so that the amount of exhaust gas discharged through the heat storage chamber As a result, the heat exchange mediated by the heat storage chamber is suppressed, the temperature of the exhaust gas supplied into the combustion chamber decreases, and the temperature inside the combustion chamber decreases. Since the second sensor detects this temperature decrease, the first gas discharge amount supplied to the heat exchanger is reduced based on the detection value of the second sensor. When the first gas emission amount decreases, the amount of exhaust gas discharged through the heat storage chamber that has temporarily decreased increases, so that heat exchange mediated by the heat storage chamber is promoted and the temperature of the exhaust gas supplied to the combustion chamber rises. Then, the temperature in the combustion chamber rises so as to return to the original state. As a result, it is possible to prevent the temperature in the combustion chamber from fluctuating with the load change of the heat exchanger, and as a result, it is possible to avoid an abnormal temperature rise. Further, the decrease of the first gas discharge amount suppresses the rise of the heat medium temperature (or pressure), and the stable exhaust heat recovery can be maintained.

Next, the adjustment of the first and second gas discharge amounts by the discharge amount adjusting means 23 will be described based on a concrete example. Here, it is assumed that the exhaust gas to be treated supplied to the combustion chamber 4 contains a combustible organic solvent. Further, the first set temperature for controlling the temperature inside the combustion chamber 4 by the combustion control means 8 is 810 ° C., and the second set temperature inside the combustion chamber 4 for controlling the second gas discharge amount by the discharge amount adjusting means 23 is 850 ° C. It is assumed that the third set temperature of the heat medium for adjusting the first gas discharge amount by the discharge amount adjusting means 23 is 200 ° C.

Here, assuming that the temperature inside the combustion chamber 4 is 820 ° C., the combustion control means 8 determines that the temperature inside the combustion chamber 4 is higher than the first set temperature of 810 ° C.
The combustion amount in the combustion chamber 4 and the supplied combustion air amount are zero without performing the combustion in 2. In other words, the combustion energy of the combustible components in the exhaust gas supplied into the combustion chamber 4
The internal temperature is 820 ° C. Next, assuming a case where the load on the heat exchanger 24 decreases under such a situation, the outlet temperature of the heat medium rises and the temperature detected by the first sensor 28 rises. When the detected temperature exceeds the third set temperature 200 ° C., the opening degree of the first damper 25 is reduced to reduce the first gas discharge amount. As a result, the amount of high-temperature exhaust gas from the combustion chamber 4 flowing into the heat exchanger 24 decreases, the outlet temperature of the heat medium decreases, and the temperature is controlled to the third set temperature. On the other hand, the combustion chamber 4
The exhaust gas amount (first gas exhaust amount) discharged from the vehicle through the first bypass route 21 decreases, so the exhaust gas amount passing through the heat storage chamber 3 and discharged to the exhaust route 6 increases by the decrease amount. The heat energy given from the heat storage chamber 3 to the exhaust gas to be processed which passes through the heat storage chamber 3 and is supplied to the combustion chamber 4 increases. Therefore, the temperature inside the combustion chamber 4 rises above 820 ° C. Here, when the temperature inside the combustion chamber 4 detected by the second sensor 29 exceeds the second set temperature 850 ° C., the discharge amount adjusting means 23 increases the opening degree of the second bumper 26 to increase the second gas discharge amount. Is increased to suppress the increase in heat energy given to the exhaust gas to be processed which is supplied to the combustion chamber 4 through the heat storage chamber 3 and is controlled so that the temperature inside the combustion chamber 4 does not exceed 850 ° C. . Therefore, abnormal temperature rise inside the combustion chamber 4 can be avoided in advance.

In the second embodiment, the discharge amount adjusting means 23
Adjusts the first gas discharge amount and the second gas discharge amount based on the detection value of the first sensor 28. Specifically, the first
Based on the detection value of the sensor 28, when the temperature of the heat medium rises, the opening degree of the first bumper 25 is reduced to reduce the first gas discharge amount, and the opening degree of the second bumper 26 is increased to increase the second amount. When the gas discharge amount is increased, and conversely, when the temperature of the heat medium is decreased, the opening amount of the first bumper 25 is increased to increase the first gas discharge amount, and at the same time, the opening amount of the second bumper 26 is decreased. The opening amount of the first bumper 25 and the second bumper 26 is adjusted so as to reduce the 2 gas discharge amount and maintain the sum of the 1st and 2nd gas discharge amounts constant regardless of the outlet temperature of the heat medium. . As a result, even if the load of the heat exchanger 24 changes, the total sum of the first and second gas emissions does not change,
Since the thermal energy given to the exhaust gas to be treated that passes through the heat storage chamber 3 and is supplied to the combustion chamber 4 does not change, the temperature inside the combustion chamber 4 can be prevented from being affected by the load fluctuation of the heat exchanger 24. .

In the second embodiment, when the load on the heat exchanger 24 is reduced, unlike the first embodiment, the temperature rise inside the combustion chamber 4 is estimated in advance and the second gas discharge amount is increased in advance. Therefore, the influence of the load fluctuation of the heat exchanger 24 can be better avoided as compared with the first embodiment. However,
When the content of the combustible component in the exhaust gas supplied into the combustion chamber 4 fluctuates, the temperature rise inside the combustion chamber 4 may occur due to the fluctuation, and is caused by other than the load fluctuation of the heat exchanger 24. In order to avoid the abnormal temperature rise inside the combustion chamber 4, the first embodiment is excellent.

Therefore, in the third embodiment, the first and second
The configuration has both features of the embodiment.
That is, the discharge amount adjusting means 23 adjusts the second gas discharge amount based on both detection values of the first sensor 28 and the second sensor 29. Specifically, based on the detection value of the first sensor 28, when the temperature of the heat medium rises, the opening degree of the first bumper 25 is reduced to reduce the first gas discharge amount and the second bumper 26 is opened. When the temperature of the heat medium decreases, the first bumper 25 increases.
Is increased to increase the first gas discharge amount, the second bumper 26 is decreased to decrease the second gas discharge amount, and the sum of the first and second gas discharge amounts is calculated as The opening degrees of the first bumper 25 and the second bumper 26 are adjusted so that the medium temperature is maintained constant regardless of the outlet temperature. As a result,
Even if the load of the heat exchanger 24 fluctuates, the total amount of the first and second gas emissions does not fluctuate. Therefore, the heat energy given to the exhaust gas to be processed which passes through the heat storage chamber 3 and is supplied to the combustion chamber 4. Since it does not change, it is possible to prevent the temperature inside the combustion chamber 4 from being affected by the load fluctuation of the heat exchanger 24. Also,
When adjusting the second gas discharge amount, while adjusting based on the detection value of the first sensor 28, the detection value of the second sensor, that is, the temperature inside the combustion chamber 4 is a predetermined set value (second set temperature). ) Is exceeded, the opening degree of the second bumper 26 is increased to increase the second gas discharge amount, and the second exhaust gas is supplied to the exhaust gas to be processed which passes through the heat storage chamber 3 and is supplied to the combustion chamber 4. The temperature energy inside the combustion chamber 4 is suppressed by adjusting the generated heat energy to be small.

Since the third embodiment has the adjustment of the second gas discharge amount based on the detection value of the second sensor, it is not always necessary to keep the sum of the first and second gas discharge amounts constant. There is no. That is, when the load on the heat exchanger 24 is reduced, the first gas emission amount is decreased by the increase in the detection value of the first sensor 28, but the decrease amount is not all the increase amount of the second gas emission amount but the increase amount. The minute may be less than or equal to the decrease. Therefore, along with this, a certain increase in the thermal energy given to the exhaust gas to be treated that passes through the heat storage chamber 3 and is supplied to the combustion chamber 4, that is, the temperature inside the combustion chamber 4 is expected to rise, If the rise is equal to or lower than the second preset temperature, the exhaust gas passing through the heat storage chamber 3 and discharged from the combustion chamber 4 has higher thermal efficiency, and thus the highly efficient operation of the device of the present invention can be achieved.

Next, a fourth embodiment will be described. In the fourth embodiment, the discharge amount adjusting means 23 includes the first sensor 2
If the temperature of the heat medium rises based on the detection value of 8, the second
The opening degree of the bumper 26 is increased to increase the first gas discharge amount, and conversely, when the temperature of the heat medium is decreased, the opening degree of the second bumper 26 is decreased to decrease the second gas discharge amount.
The opening degree of the second bumper 26 is adjusted. Further, the discharge amount adjusting means 23 decreases the opening amount of the first bumper 25 to decrease the first gas discharge amount when the temperature inside the combustion chamber 4 rises, based on the detection value of the second sensor 29, to decrease the first gas discharge amount. In addition, the opening degree of the first bumper 25 is adjusted so that the opening degree of the first bumper 25 is increased and the first gas discharge amount is increased when the temperature inside the combustion chamber 4 decreases. The method of the present invention is realized by the discharge amount adjusting means 23 executing the adjustment process of the first and second gas discharge amounts as described above. In the fourth embodiment, the correspondence relationship between the detection values of the first sensor 28 and the second sensor 29 and the first and second gas discharge amounts is opposite to that of the first embodiment.

Next, the adjustment of the first and second gas discharge amounts by the discharge amount adjusting means 23 in the fourth embodiment will be described based on a concrete example. Here, it is assumed that the exhaust gas to be treated supplied to the combustion chamber 4 contains a combustible organic solvent. Further, the first set temperature for controlling the temperature inside the combustion chamber 4 by the combustion control means 8 is 810 ° C., and the fourth set temperature inside the combustion chamber 4 for controlling the first gas discharge amount by the discharge amount adjusting means 23 is 835 ° C. The fifth preset temperature of the heat medium for adjusting the second gas discharge amount by the discharge amount adjusting means 23 is 20.
The case of 0 ° C is assumed.

Here, assuming that the temperature inside the combustion chamber 4 is 835 ° C., the combustion control means 8 determines that the temperature inside the combustion chamber 4 is higher than the first set temperature of 810 ° C.
The combustion amount in the combustion chamber 4 and the supplied combustion air amount are zero without performing the combustion in 2. In other words, the combustion energy of the combustible components in the exhaust gas supplied into the combustion chamber 4
The internal temperature is 820 ° C. Next, assuming a case where the load on the heat exchanger 24 decreases under such a situation, the outlet temperature of the heat medium rises and the temperature detected by the first sensor 28 rises. When the detected temperature exceeds the fifth set temperature 200 ° C., the opening degree of the second damper 26 is increased to increase the second gas discharge amount. As a result, the amount of exhaust gas discharged through the heat storage chamber 3 is reduced by the increase amount, so that the exhaust gas to be processed supplied through the heat storage chamber 3 and supplied to the combustion chamber 4 is given from the heat storage chamber 3. The heat energy generated is reduced, and the temperature inside the combustion chamber 4 drops below 835 ° C. Where the second
When the sensor 29 detects a temperature decrease in the combustion chamber 4 below the fourth set temperature 830 ° C., the emission amount adjusting means 23 makes the first
Since the opening degree of the bumper 25 is reduced to reduce the amount of high-temperature exhaust gas (first gas discharge amount) flowing from the combustion chamber 4 into the heat exchanger 24, the outlet temperature of the heat medium is lowered to the fifth setting. The temperature is controlled at 200 ° C. Further, the first gas discharge amount decreases, and the amount of exhaust gas discharged through the heat storage chamber 3 that has decreased temporarily returns to the original state, so that the temperature inside the combustion chamber 4 that has decreased temporarily is The temperature rises so as to return to 835 ° C. and is controlled to a constant temperature.
