摘要： PURPOSE:To reduce the quantity of the nitrogen oxide contained in exhaust gas without reducing the deodorizing efficiency of ozone deodorization by exhausting the air after deodorization out of a device in the state diluted by the undeodorized air supplied from the outside of the device through an air supply part. CONSTITUTION:The air deodorized through an ozone generator 3 and an ozone decomposer 4 is mixed with the untreated air supplied from an air supply passage 5 by a fan 2, and discharged out of a machine through an exhaust hole 12 in the state diluted by the untreated air, and thus the concentration of nitrogen oxide in the exhaust gas is reduced. The degree of reduction in nitrogen oxide concentration in the exhaust gas depends on the ratio of the flow rate per unit time of the deodorized air to the flow rate per unit time of the untreated air. When the treated air quantity is 3m /min, and the one-hour value of nitrogen oxide in the air just after deodorization is 0.02ppm, the flow rate of the air to be deodorized and the flow rate of the untreated air are set to 1.5m /min. and 1.5m /min., respectively, to make the nitrogen oxide one-hour value in the exhaust gas 0.01ppm.

A fan 6 is actuated, raw material air is taken through an air inlet 1, passed through the dehumidifier 2 and dehumidified, introduced into the ozonizer 4, and ozonized by silent discharge. Also, during shutdown of the ozonizer 4, a heater 3 is actuated by a command from a control means 7 to heat the dehumidifying agent in the dehumidifier 2 to effect its renewal. The operational efficiency can further be improved by using such a design that two or more dehumidifiers 2 are prepared and connected alternately to the ozonizer 4 to generate ozone, and concurrently with this, the dehumidifying agent in the dehumidifier(s) 2 not connected to the ozonizer 4 is renewed by heating.
