摘要

厨房烹饪是民居室内PM

2.5

污染物的重要来源

为对其进行有效控制

提出了空气幕送风方式。建立厨房物理模型

使用Fluent软件对厨房内的气流组织、温度分布和PM

2.5

浓度分布进行了数值模拟。研究了空气幕对厨房内PM

2.5

和热流的控制效果

并对3种射流速度进行对比分析。研究结果表明: 空气幕射流气流对烹饪区域产生了很好的包裹效应

可以阻隔PM

2.5

的扩散和热流的蔓延; 可使厨房内PM

2.5

排除率提高到44%~75%

平均降温1~2 ℃。当空气幕射流速度为0.6 m/s时

控制效果最佳。研究结论可对厨房PM

2.5

污染的防治提供参考

为空气幕送风系统的研究提供模拟数据和理论依据。

Abstract

Cooking in the residential kitchen is an important source of indoor PM

2.5

. In order to control PM

2.5

effectively

the air curtain is proposed as an air supply means. A model of the kitchen is built and a numerical simulation

including airflow organization

temperature distribution and PM

2.5

concentration distribution in the kitchen

is performed by using the Fluent software. A numerical simulation is performed to study the control effect of PM

2.5

pollutants and heat flow in the kitchen. Three kinds of jet velocities are compared and analyzed. The results of this study show that the jet flow of an air curtain has a good wrapping effect on the cooking area

which can obstr

uct the diffusion of PM

2.5

and the spread of heat flow. The PM

2.5

removal rate can be increased to 44%~75%

and the average temperature in the kitchen can be lowered by 1~2 °C by using the air curtain to supply air. The control effect is optimal when the air curtain jet velocity is 0.6 m/s. The research productions have reference for the prevention and treatment of PM

2.5

pollution in the kitchen and can provide simulation data and a theoretical basis for the study of the air curtain air supply system.
