The use of ozone is expected to increase in the future, mainly in fields such as water treatment, sterilization, and air purification, but ozone remains in exhaust gas. Further, ozone is produced as a by-product from various discharge tubes and is discharged as is. The emitted ozone often exceeds environmental standards for air pollution, and must be treated.

In the present invention, fibers of inorganic or organic polymer resin such as glass or metal, sponge-like, net-like, felt-like fibers are used as a carrier, and manganese, nickel, cobalt, copper, silver, zinc, etc. are coated on the surface of the carrier. Since a filter medium supporting one or more metal oxide catalysts such as, preferably, a hollow cylindrical filter medium supporting manganese oxide alone or manganese oxide together with other metal oxides is used, the ratio is By making the surface area of 0.005m 2 /cm 3 or more, which is much larger than that of conventional granular catalysts, and by aerating the ozone-containing gas to be treated through this hollow cylindrical filter material, The layer thickness allows processing with a large ventilation rate.

防止して通気処理することが必要である。 Furthermore, as the amount of water entrained in the gas to be treated increases, ozone decomposition tends to become insufficient.
This problem is caused by the fact that the surface of the filter material, which is a catalyst, becomes wet with moisture, which inhibits contact with the gas to be treated. In order to prevent this, it is necessary to adjust the relative humidity of the gas to be treated to 80% or less by heating, cooling, dehumidifying with a dehumidifying agent, etc. to prevent moisture condensation and perform ventilation treatment.

Alternatively, by ventilating the gas to be treated with a comparative humidity of 80% or less from the outside to the inside, we can achieve unprecedented thin layer thickness and high aeration speed, for example, with a hollow cylindrical filter medium thickness of 50 to 200 mm. ~10000N
Effective treatment can be achieved by changing the aeration rate of m 3 -gas to be treated/m 3 -filtering material/h.

い高速処理を可能にする。 In this case, the surface area of the filter medium is large at 0.005 m 2 / cm 3 or more, but because it is formed in a hollow cylindrical shape, it is possible to use a thin layer with a thickness of 50 to 200 mm without increasing the pressure loss. It is possible to perform treatment at a high aeration rate of 10000Nm 3 -target gas/m 3 -filter material/h, enabling high-speed processing that cannot be achieved with conventional granular catalysts.

As described above, according to the present invention, the filtration material used has an extremely large surface area, which is formed into a hollow cylindrical shape by supporting manganese or other metal oxide catalysts on the surface of inorganic fibers or organic polymer resin fibers. It has low pressure loss and enables high-speed processing that cannot be achieved with conventional granular catalysts. Furthermore, by adjusting the relative humidity of the gas to be treated to less than 80%, it ensures effective treatment and is highly safe. It is economical, and the hollow cylindrical filter material allows the device to be made smaller and lighter, making it compact and easy to maintain, and many other beneficial effects can be expected.
