1、體積小，材料消耗少，操作與檢修方便。
1, small size, less material consumption, easy operation and maintenance.
2、產(chǎn)塵點(diǎn)固定、產(chǎn)塵氣流速度較小且連續(xù)產(chǎn)塵的地點(diǎn)。
2, the production of dust points fixed dust production airflow smaller and continuous dust production sites.
3、采用氣幕抑制污染物擴(kuò)散，具有氣量小，抗干擾能力強(qiáng)，不影響工藝操作、效果好的特點(diǎn)。
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、集氣罩的吸氣方向與污染氣流運(yùn)動(dòng)方向一致，充分利用污染氣流的初始動(dòng)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.
