摘要: | 本研究模擬密閉式豬舍,以複層牆為豬舍設計,於複層牆內空氣層噴霧,並於噴霧系統中添加木酢液去除氨氣,使用抽風扇進行空氣層與室內空氣循環,此方法主要利用畜舍牆體內空間進行環境改善操作,改善過程不至於改變畜舍內的溫度、濕度、風速等環境因子,更能維持畜舍熱環境的穩定管理,以提供夏季涼爽且除臭的畜舍環境。
降溫方面,探討噴霧壓力、噴霧時間、間歇時間對降溫效果的影響,並以溫濕度指數判斷是否達改善效果;除氨方面,探討噴霧壓力、噴霧時間、木酢液稀釋濃度對氨氣去除效果的影響。綜合兩者,提出最佳的噴霧策略。 本設施最佳的噴霧策略,為噴霧壓力50 kg/ ,噴霧時間25秒,間歇時間為0.5分鐘,木酢液稀釋倍數為100倍,此操作策略可達室內降溫與去除舍內氨氣異味的效果,並以溫濕度指數值設定噴霧關閉條件,以達舒適豬舍環境管理之目的。 This study using double-layer wall as swine barn design to simulated the sealed swine barn . Use fog spray system inside the wall to cool down the temperature, and add proper Pyroligneous acid into spray system to eliminate the ammonia. This method mainly uses the space inside the wall of the house to improve the environmental operation. The improvement process does not change environment factors such as temperature, humidity and wind speed rapidly, thus maintains better thermal environment managements to provide a cooler and stinkless livestock house environment The effects of cooling ability of spray pressure, operating time and rest time were discussed and the improvement effect is determined by THI(temperature-humidity index); addition to get rid of ammonia, discuss spray pressure, operating time and Pyroligneous acid dilution effect on the ammonia removal effects. Combine of these two strategies and then propose the best spray strategy. The best spray strategy of this facilities is spray pressure 50 kg/cm2, operating time of 25 seconds, rest time of 30 seconds and Pyroligneous acid dilution 100 times. This strategy can cool down the indoor temperature and remove ammonia. Meanwhile, we can provide a more comfortable livestock environment by using THI value as on /off condition. |
