Description of the Related Art Exhaust gas from paint drying ovens and air-conditioning exhaust gas in printing plants contain harmful and odorous substances such as organic silicon, organic solvents, phosphorus, arsenic, and lead. And about 95% of the harmful and odorous substances are organic silicon. Conventionally, exhaust gases containing these harmful and odorous substances are supplied to a combustion deodorizer to burn and remove harmful and odorous substances, and then released to the atmosphere as processing gas. Incidentally, the combustion deodorizing apparatus is roughly classified into a heat storage combustion system and a catalytic combustion system. In the heat storage combustion system, for example, a plurality of heat storage bodies are provided in a combustion chamber having a combustion device, and harmful and odorous substances in exhaust gas are burned in the combustion chamber, and the combustion gas (processing gas) is passed through the heat storage body to store heat. On the other hand, the preheated exhaust gas containing harmful and malodorous substances is supplied to the other heat accumulators stored as described above and then supplied to the combustion chamber, and the heat accumulators for heat accumulation are sequentially switched to be deodorized by combustion. The catalytic combustion method burns harmful and odorous substances in exhaust gas with a catalyst.

換器を閉塞するという問題を有する。However, in the regenerative combustion system, exhaust gas containing harmful and odorous substances (hereinafter referred to as "exhaust gas") is preheated by a regenerator filled with a regenerative material such as ceramic. Silicon is thermally decomposed at about 200 ° C. to generate a sticky substance such as tar, and this sticky substance adheres to the heat storage material, and furthermore, inorganic silicon formed by thermal decomposition of organic silicon adheres to the heat storage body. It has problems such as blockage and hindrance to exhaust gas treatment. The regenerator is a regenerative heat exchanger in which the exhaust gas and the processing gas are intermittently preheated by sequentially switching and supplying the exhaust gas and the processing gas to the same passage. It is also possible to provide a heat exchanger that supplies the processing gas to another passage and continuously preheats the exhaust gas. However, even in this case, there is a problem that the heat exchanger is similarly blocked.

Therefore, in the catalytic combustion system, an alumina-based pretreatment agent is disposed upstream of the platinum catalyst,
Exhaust gas obtained by oxidatively decomposing organic silicon with the alumina pretreatment agent is supplied to a platinum catalyst to prevent the platinum catalyst from deteriorating. At this time, it is necessary to raise the temperature of the exhaust gas to 350 ° C. or more for the organic silicon to undergo an oxidation reaction with the alumina-based pretreatment agent.

Exhaust gas from a coating and drying furnace containing organic silicon and toluene is passed through a filter 1 to remove foreign particles and the like mixed in the exhaust gas. It is preheated to about 265 ° C. in the heat exchanger 3 and supplied to the alumina pretreatment agent 4. In this case, the alumina-based pretreatment agent 4 needs 3 to react with the organic silicon.
Since a temperature of 50 ° C. or more is required, the temperature of the exhaust gas is increased to 350 ° C. by the preheating burner 5 and the alumina pretreatment agent 4
To remove organic silicon in advance. Then, the exhaust gas from which the organic silicon has been removed reaches the platinum catalyst 6, and the organic solvent in the exhaust gas, for example, a harmful or odorous substance such as toluene, is burned and deodorized. , And is discharged from the chimney 7 through the preheating heat exchanger 3. The concentration of toluene per 1 m 3 N is 100.
At 0 ppm, the temperature rise due to combustion is 126.4 ° C.

It is necessary to preheat and supply to the alumina-based pretreatment agent 4, which requires energy. In addition, since the organic solvent and the like in the exhaust gas are oxidized and decomposed (combusted) by the platinum catalyst 6, the processing gas is heated to a high temperature. become. Furthermore, since the alumina-based pretreatment agent 4 is expensive, it has to be replaced every time it is coated with inorganic silicon and its processing ability is reduced, so that there is a problem that the running cost is increased.

する。[0007] The inventors of the present invention have studied a pretreatment agent in order to eliminate the disadvantages of each of the above methods, and as a result, have paid attention to a porous adsorbent containing activated carbon as a main component. This adsorbent also adsorbs malodorous substances other than organic silicon, but since organic silicon has a relatively high boiling point and a large molecular weight, it is easier to adsorb than malodorous substances with a low boiling point and a small molecular weight,
It has been found that the previously adsorbed malodorous substance is driven out and selectively adsorbed, and that the adsorbent maintains sufficient adsorption performance even at 20 to 100 ° C. where the alumina-based pretreatment agent is significantly deteriorated. Therefore, an object of the present invention is to provide a combustion deodorization method for an organic silicon-containing exhaust gas that solves the above-mentioned problem by adsorbing and removing organic silicon in the exhaust gas with a porous adsorbent such as activated carbon and then burning. .

It is explained according to. In the figure, an exhaust gas (20 ° C.) containing organic silicon, toluene, etc.
After the foreign matter is removed by the blower 12, the foreign matter is supplied to the pretreatment agent 14 composed of a porous adsorbent containing activated carbon as a main component by the blower 12, and the organic silicon is adsorbed to the pretreatment agent 14 while passing through the pretreatment agent 14. Removed. Thereafter, in the combustion deodorization apparatus during the steady operation, the exhaust gas is preheated to about 190 ° C. by exchanging heat with the processing gas in the preheating heat exchanger 13 and reaches the platinum catalyst 16. In the platinum catalyst 16, since the exhaust gas has already been heated to 190 ° C. necessary for an oxidation reaction with the platinum catalyst, combustible components such as organic solvents in the exhaust gas are burned to become a processing gas at about 350 ° C. After the heat exchange with the exhaust gas in the preheating heat exchanger 13 as described above, the exhaust gas is discharged from the chimney 17.

イト等を使用してもよい。If the organic solvent is, for example, toluene as described above, the toluene concentration in the exhaust gas is lower than the self-flammable limit concentration of 1,300 ppm in the platinum catalyst 16, or the combustion deodorizer is in a steady operation. If the exhaust gas is not self-burning due to low temperature in the early stage of work,
It is necessary to burn the preheating burner 15 to raise the exhaust gas temperature to 190 ° C. When the organic solvent starts burning on the platinum catalyst 16, the temperature of the platinum catalyst 16 itself rises and the exhaust gas temperature also rises. Thereafter, the combustion of the preheating burner 15 depends on the temperature of the processing gas leaving the platinum catalyst 16. The amount is adjusted to maintain a steady operation (in the case of toluene having a concentration of 1300 ppm as described above, the temperature of the processing gas leaving the platinum catalyst 16 is adjusted to 350 ° C.). Also in this case, since the preheating burner 15 does not always burn as in the conventional catalytic combustion system, energy saving can be achieved as compared with the conventional one. Note that, instead of the preheating heat exchanger 13, a regenerative heat exchanger is used, and the exhaust gas and the combustion gas are alternately communicated with each other, or the regenerator is rotated so that the exhaust gas is stored in a portion stored by the combustion gas. It may be supplied and preheated. Further, a hydrophobic zeolite or the like may be used instead of activated carbon as the porous adsorbent.

However, even in a heat storage combustion system, a porous adsorbent is provided on the upstream side of the heat storage body to remove exhaust gas from which organic silicon has been removed. What is necessary is just to preheat.

トを大幅に軽減することができる。As is apparent from the above description, according to the present invention, the organic silicon is selectively adsorbed and removed from the exhaust gas and then deodorized by combustion. Prevent clogging of the heat storage body due to adhesion of tar and inorganic silicon, and in the catalytic combustion system,
Since the pretreatment agent does not oxidize as in the conventional alumina system, but adsorbs and removes organic silicon at room temperature, the exhaust gas is heated to 350 ° C in the pretreatment stage as in the case of using an alumina system. There is no need to save energy. Further, in the present invention, when the exhaust gas from which the organic silicon has been removed is supplied to a combustion deodorization apparatus, the exhaust gas may be preheated. This preheating is performed based on the processing gas temperature after the combustion deodorization. Depending on the temperature of the processing gas, it is not necessary to perform preheating (it is not always preheated), so that energy saving can be achieved as compared with the conventional one. If heat exchange with the processing gas is used to raise the temperature of the exhaust gas to the temperature required for oxidative decomposition with a platinum catalyst (190 ° C.), it is not necessary to steadily burn the burner, thereby further saving energy. Can be. In addition, if activated carbon is used as the pretreatment agent, the cost is lower than that of an alumina-based material, so that the running cost can be greatly reduced.
