DEODORIZER HAVING FUNCTION OF REDUCING FINE DUST AND ODOR with function of reducing fine dust and odor

The present invention relates to a deodorizer, and more particularly, to a deodorizer installed in a livestock house and capable of simultaneously reducing fine dust and odor contained in air discharged from the inside of the livestock house.

In general, in the case of a barn built to raise livestock such as cattle and pigs in large quantities, a large amount of odor gases such as ammonia gas and fine dust are generated due to the excrement, feed, and other moisture of the livestock. In the case of discharge as a result, many civil complaints have been filed from neighboring residents due to odor or fine dust. Nevertheless, in a conventional barn (for example, a pig house), only a ventilation port for ventilating or exhausting the internal air is installed, and the installation rate of a separate odor reduction facility (deodorizer) is very low. Even if a deodorizer is installed, the facility cost is very high, so the supply rate is lowered, and the deodorization performance is low and there is little effect of reducing fine dust.
