1、体积小,材料消耗少,操作与检修方便。
1, small size, less material consumption, easy operation and maintenance.
2、产尘点固定、产尘气流速度较小且连续产尘的地点。
2, the production of dust points fixed dust production airflow smaller and continuous dust production sites.
3、采用气幕抑制污染物扩散,具有气量小,抗干扰能力强,不影响工艺操作、效果好的特点。
3, the use of air curtain to suppress the proliferation of pollutants, with a small amount of gas, anti-interference ability, does not affect the process operation, the effect is good.
4、集气罩的吸气方向与污染气流运动方向一致,充分利用污染气流的初始动能。
4, the hood suction direction and the direction of movement of contaminated air flow, take full advantage of the initial kinetic energy of the polluting air flow.
