【摘要】：為對保育舍內(nèi)環(huán)境質(zhì)量狀況進(jìn)行評估和改善舍內(nèi)環(huán)境提供有益參考,應(yīng)用CFD對采用負(fù)壓通風(fēng)和水泡糞保育豬舍的氣流場、溫度場、濕度場和顆粒物濃度場進(jìn)行三維穩(wěn)態(tài)模擬。由模擬結(jié)果可知:在冬季送入氣流,舍內(nèi)動(dòng)物所在區(qū)域高度為0.2 m的風(fēng)速基本保持在0~0.2 m/s,大部分區(qū)域風(fēng)速在0.1 m/s以下,相對濕度則基本在60%~70%之間,舍內(nèi)的平均溫度保持在26~34℃,大部分區(qū)域的PM_(2.5)、PM_(10)和TSP質(zhì)量濃度分別在0~0.1 mg/m~3、0~0.7 mg/m~3和0~1.0 mg/m~3之間。由《規(guī)模豬場環(huán)境參數(shù)及環(huán)境管理》可知,舍內(nèi)環(huán)境質(zhì)量基本滿足保育豬對冬季環(huán)境需求,但在單元入口及墻角處仍有優(yōu)化空間。
[Abstract]:In order to evaluate the environmental quality and improve the environment, CFD was used to simulate the airflow field, temperature field, humidity field and particle concentration field of pig shed with negative pressure ventilation and blistering manure. From the simulation results, it can be seen that in winter, the wind speed of 0.2 m in the area where the animals are located is basically kept at 0 ~ 0.2 m / s, the wind speed in most areas is below 0.1 m / s, the relative humidity is between 60% and 70%, and the average temperature in the house is kept at 2634 鈩，
