The importance of local dust collection in the purification workshop, turbulence clean room, purification workshop because the air flow is turbulence, dust can spread to any place, if the local location of dust and average affect the overall situation, it is very bad, even if the number of air changes is increased, the effect is not too high.
局部粉尘收集在净化车间重要性，乱流洁净室、净化车间内由于气流是乱流，尘粉可以扩散到任何地方，如果局部地点发尘而平均地影响全局，是很不好的，即使增加很多换气次数，效果也提不太高。
The best way is to focus on the treatment of local air flow organization, that is, to enclosure the local dust generating equipment (if not located in the clean room) and local exhaust air, set up a stainless steel local collection cover in the dust location of the purification workshop, and use the cover and pipe to concentrate the dust containing air after recycling for the dust source with a large amount of dust and a large exhaust volume.
最好的办法是从局部气流组织的处理上着眼，即对局部发尘设备（如果非设在洁净室内的话）加以围挡和进行局部排风，在净化车间散尘位置设置不锈钢局部收集罩，是对发尘量大的和排气量也大的尘源用罩子和管道先把含尘空气集中处理之后再循环的做法，
If it all goes outside, it wastes too much energy.
如果全部排至室外，能量浪费太大。
