如何计算山东无尘车间的送风量呢?

来源:http://www.henganjh.cn │ 发表时间:2019-08-26 

  如今,随着许多高科技产业的不断发展,越来越多的企业对产品生产环境提出了更高的要求。而无尘车间,是为人类活动和生产空间达到一定水平的洁净空气,其主要功能是控制颗粒物污染。然而,在山东无尘车间的使用中,送风量的计算是必不可少的。那么你知道如何计算吗?
  Nowadays, with the continuous development of many high-tech industries, more and more enterprises put forward higher requirements for the production environment of products. Dustless workshop is clean air for human activities and production space to reach a certain level. Its main function is to control particulate matter pollution. However, in the use of dust-free workshop in Shandong Province, the calculation of air supply volume is indispensable. So do you know how to calculate?
  山东无尘车间送风计算:
  Air supply calculation of dust-free workshop in Shandong Province:
  送风是用来表示通风设备(如鼓风机)的容量,单位为立方米/秒。
  Air supply is used to represent the capacity of ventilation equipment (such as blowers) in cubic meters per second.
  无尘车间送风计算与一般空调送风计算不同。一般空调(全空气系统)的送风量根据热湿负荷计算,选择经济送风温差,通过消除余热湿计算送风量。
山东无尘车间
  The calculation of air supply in dust-free workshop is different from that in general air-conditioning. The air supply volume of general air conditioning (all-air system) is calculated according to the heat and humidity load. The economic air supply temperature difference is selected and the air supply volume is calculated by eliminating the waste heat and humidity.
  无尘车间送风计算一般不依赖于热湿负荷,主要是根据不同的洁净度根据平均风速或通风次数来计算送风。如有必要,则利用热湿负荷对送风量进行校核计算,一般可满足消除多余热湿的要求。也就是说,由截面平均风速或换风量计算的送风量通常大于消除余热和湿气计算的送风量。
  The calculation of air supply in dust-free workshop generally does not depend on the heat and humidity load, but mainly on the average air speed or the number of ventilation according to different cleanliness. If necessary, the heat and humidity load is used to check and calculate the air supply volume, which can generally meet the requirement of eliminating excess heat and humidity. That is to say, the air supply volume calculated by the average cross-section wind speed or air exchange volume is usually larger than that calculated by eliminating waste heat and moisture.
  因此,由于无尘车间送风量大,送风温差减小。如果验算发现供气量不能满足消除余热和多余水分的要求,主要有两种解决方法:
  Therefore, due to the large air supply capacity in dust-free workshop, the temperature difference of air supply decreases. If the checking calculation finds that the gas supply can not meet the requirements of eliminating waste heat and excess moisture, there are two main solutions:
  第一种方法:
  The first method is:
  根据余热的消除,将剩余水分计算为洁净车间送风量(此时洁净车间水平将得到提高)。
  According to the elimination of waste heat, the residual water is calculated as the air supply capacity of clean workshop (at this time, the level of clean workshop will be improved).
  第二种方法:
  The second method:
  以上的分析是山东无尘车间余热(湿)组成,也就是说,冷负荷的构成(湿负荷),可以采取技术措施,减少无尘车间余热(湿负荷),如使用热(湿放电),绝缘,密封的方法来减少冷负荷(湿负荷),符合要求的空气供应。
  The above analysis is the waste heat (wet) composition of Shandong dust-free workshop, that is to say, the composition of cooling load (wet load) can take technical measures to reduce the waste heat (wet load) of dust-free workshop, such as the use of heat (wet discharge), insulation, sealing methods to reduce the cold load (wet load) and meet the requirements of air supply.
