Description of the Related Art It has been pointed out that exhaust gas discharged from waste incineration facilities and fly ash accompanying the exhaust gas contain various environmental pollutants, which are not released into the environment. Thus, there is a demand for suppressing the amount of pollutants in exhaust gas. And among waste incineration facilities, incineration facilities that treat municipal garbage, etc.
By the end of four years, incinerators with a throughput of more than 4 tons per hour
Dioxin concentration in exhaust gas is determined by toxic equivalent (TEQ)

３２８３７８号）が提案されている。In order to suppress the emission of dioxin in such a refuse incineration facility, there is a method of improving the combustion state of the incinerator. However, until the incinerator can be remodeled, the intermediate treatment of exhaust gas containing dioxin and the like is performed. It is necessary to adopt a method of cleaning by adding water, and a method of contacting exhaust gas with activated carbon has been proposed as such an intermediate treatment method. However, the method using expensive activated carbon greatly increases the cost of treating municipal waste, and as an alternative economical intermediate treatment method, a neutralizing absorbent such as slaked lime and heavy oil combustion ash are sprayed into the exhaust gas. This gas is brought into contact with a bag filter to form a layer comprising a neutralizing absorbent and heavy oil combustion ash, and an exhaust gas treatment method comprising contacting the bag filter with exhaust gas containing the neutralizing absorbent and heavy oil combustion ash ( JP-A-7-
No. 328378) has been proposed.

法を提供することを目的とした。However, the heavy oil combustion ash used in this method contains heavy metals, so there is a problem in disposing of the treating agent recovered after use, and there is also a problem of complicated use with a neutralizing absorbent. That was not always a satisfactory method. Therefore, the present invention has at least the same excellent dioxin removal effect as compared with the case where conventional activated carbon is used as a treating agent, is easy to use, and is easy to dispose, and is economical for exhaust gas cleaning. The purpose was to provide a chemical treatment method.

The synthetic polymer is preferably, for example, a molded article such as a thermosetting synthetic resin, a thermoplastic synthetic resin, or a synthetic rubber. Among them, a scrap obtained in a manufacturing process of a molded article, a waste after use of the molded article, or a crushed product thereof. A processed molded article that is not suitable for reuse as a material for producing a molded article can be suitably used. Examples of the processed molded article of a synthetic polymer suitable for use as a raw material of such a cleaning agent include a rubber vulcanizate, particularly a waste tire.

であっても差し支えない。[0007] When disposing of such a synthetic polymer processed body, it is usually incinerated, but when it is processed in large quantities, it is used as a heat source for a boiler or the like. In such a case, it is usual to use an auxiliary fuel for efficient and complete combustion, but the flue dust obtained when using coal as the auxiliary fuel is used as a cleaning agent in the present invention. It is suitable. Here, any kind of coal that is used as fuel for the combustion furnace and is also a raw material of the dust may be used, and the particle size and form of the coal may be in any form such as fine powder, powder, granule, and lump.

Any purpose may be used, and the installation purpose of the combustion furnace may be anything, such as for waste treatment, heat recovery, and power generation boiler, or for the production of the cleaning agent of the present invention. Further, dust generated by burning the synthetic polymer and coal in the combustion furnace can be separated from the exhaust gas by using an appropriate collecting device such as an electric dust collector, a cyclone, and a bag filter. Although it is possible, the separation method is not particularly limited.

Things. However, when the contact temperature between the cleaning agent and the exhaust gas is too low, the efficiency of removing environmental pollutants decreases, and when it is too high, the efficiency of removing dioxins and the like tends to decrease. It is desirable that the exhaust gas is contacted at a temperature of 100 ° C. or higher, preferably 150 ° C. or higher, and up to about 200 ° C.

点がある。According to the method for purifying exhaust gas of the present invention, a cleaning agent containing dust generated by simultaneous combustion of a synthetic polymer and coal is brought into contact with the exhaust gas to reduce environmental pollutants contained in the exhaust gas. In particular, in addition to mercury and dioxin, for example, there is an effect that an acidic substance such as a sulfur compound can be extremely efficiently removed. Moreover, the cleaning agent used in the present invention can be produced economically while recovering thermal energy from a polymer waste or the like that has conventionally been considered difficult to dispose of as a raw material. This is advantageous in that it is extremely economical to purify exhaust gas discharged from municipal garbage incineration facilities, in which the implementation of environmental pollution countermeasures tends to be delayed due to the increased cost of cleaning.
