Field of the Invention The present invention is capable of purifying environmental pollutants such as dioxin in combustion exhaust gas discharged from an incinerator by oxidative decomposition at a high temperature by a photocatalytic reaction and purifying the same. Moreover, the present invention relates to an exhaust gas purification method that can be installed in an existing incinerator.

られている。2. Description of the Related Art As an exhaust gas purifying method for treating flue gas discharged from an incinerator, conventionally, an electric dust collector, a bag filter or a cyclone is provided in a flue gas discharge passage to remove dust in the flue gas. There is known a method of adsorbing and removing dioxin and the like in combustion exhaust gas by using an adsorbent such as activated carbon or activated coke.

An apparatus for collecting a photocatalyst by a duster is disclosed.

ためにその機能を十分に発揮できず、全体としては、光
触媒による排ガス処理の効率が著しく低下するという欠
点があった。However, according to the purification method using the apparatus described in JP-A-5-285342, since the photocatalyst is mixed into the combustion exhaust gas, the transparency of the exhaust gas is extremely high. Therefore, the photocatalysts located in the area relatively close to the light source can exhibit sufficient functions, but the photocatalysts at some distance from the light source are not sufficiently irradiated with the excitation light, so that their functions are not sufficient. However, there was a disadvantage that the efficiency of the exhaust gas treatment by the photocatalyst was significantly reduced as a whole.
【０００５】また、処理後の分解ガスから光触媒を分離
回収するために集塵機が必要となり、装置が全体として
複雑化し、高価なものになるという問題もあった。In addition, a dust collector is required to separate and recover the photocatalyst from the decomposed gas after the treatment, and there has been a problem that the apparatus becomes complicated as a whole and becomes expensive.

ことができないという問題があった。On the other hand, in a purification method using an apparatus for collecting and removing harmful substances such as dioxin in flue gas by providing an electrostatic precipitator, a bag filter, or a cyclone, the gas is contained in the flue gas. Among the dioxins, those contained in the dust can be removed together with the dust, but there is a problem that dioxin attached to extremely fine fly ash and gaseous dioxin having a low boiling point cannot be removed.

る。Further, when such harmful substances are collected and removed by a dust collector, for example, the combustion exhaust gas discharged from the incinerator has a high temperature, so that it is necessary to rapidly cool it by using a cooling device before introducing it into the dust collector. As a result, the apparatus as a whole has become complicated and expensive. The same can be said for a device using a bag filter or a cyclone.

った。For this reason, it has been proposed to introduce oxidative decomposition or reductive decomposition using a metal catalyst such as titanium, vanadium or platinum as an auxiliary means. However, according to the oxidative decomposition and reductive decomposition methods using a metal catalyst, the effective temperature atmosphere is around 230 ° C. and narrow, and as described above, the combustion exhaust gas is rapidly cooled using the cooling device, and then the dust collector and the baggage are removed. Since the gas was introduced into the filter and cyclone, it was necessary to heat the cooled flue gas again to raise the temperature, which made it very troublesome to control the temperature of the flue gas.

が顕在化していた。In the above-mentioned purification method using an adsorbent such as activated carbon or activated coke, although gaseous dioxin having a low boiling point can be removed in theory, secondary purification of a used waste adsorbent having adsorbed dioxin can be performed. If treatment is required and the combustion exhaust gas temperature is 150 ° C. or higher, the adsorbed dioxin may be desorbed and released, or the adsorption performance of activated carbon may be reduced and the desired adsorption and removal may not be performed. Further, since the temperature of the flue gas is usually fluctuated, various problems have become apparent, such as the adsorbed dioxin being desorbed and re-scattered in the flue gas at a high temperature.

An object of the present invention is to provide a method for purifying combustion exhaust gas which can oxidatively decompose a representative environmental pollutant or the like at a high temperature by a photocatalyst and thereby purify the pollutant to an extent that it can be released into the atmosphere.
