Description of the Related Art Odor components generated from animal breeding rooms include ammonia, amines such as trimethylamine, and lower fatty acids such as valeric acid. Conventionally, acid-impregnated activated carbon, alkali-impregnated activated carbon, and the like have been used to remove these odor components, but these activated carbons have a short life as an adsorbent. In addition, the method of washing gas containing odor components with an aqueous acid solution or an aqueous alkali solution is preferable when the concentration of amines such as trimethylamine and lower fatty acids such as valeric acid is extremely low as in exhaust gas from animal breeding rooms. The removal rate is low, and the deodorizing effect becomes insufficient.
In addition, there are many problems, such as a problem of treating waste liquid after washing.

Take in outside air from the outside air intake (4) in the air conditioner,
After removing coarse dust by passing through a filter (5), it is brought into contact with atomized water. Next, the air is sent to the heater (6), the temperature and humidity are adjusted, and the temperature and humidity are guided to the activated carbon deodorizing unit (7). The odor component is completely absorbed and removed by contact with the activated carbon, and then sent to the animal breeding room (1). . The circulating air is blown by a blower (8) installed in a duct connecting the air conditioner (3) and the heater (6), but the installation location is not particularly limited as long as it is installed in the duct. Since the outside air is partially (around 30%) taken in by the air conditioner (3), surplus air is exhausted by the exhaust fan (12) installed at the exhaust port (2 ') of the breeding room. In this case, it is preferable that the air containing the odor component discharged passes through the deodorization tower (13).
