实验室的污染源来自哪些地方?

来源:http://www.sdrunjing.com/ 日期:2020-04-13 发布人:润静小编
  洁净实验室是一种特殊的实验室,它利用空间污染控制技术对空气和环境参数进行预设的人工控制,对实验室空气中悬浮粒子浓度控制有限的空间。它的建造和使用应能减少粒子在空间中的滞留、产生和滞留。清洁实验室需要控制的三大污染源是什么?
  Clean laboratory is a special kind of laboratory. It uses the technology of space pollution control to control the air and environment parameters manually, and to control the concentration of suspended particles in the air of the laboratory in a limited space. It should be constructed and used to reduce the retention, generation and retention of particles in space. What are the three major pollution sources that clean laboratories need to control?
  1.外部污染源
  1. External pollution sources
  大气尘埃是清洁实验室直接处理的对象。在清洗技术中,更常用的浓度是颗粒数≥0.5 m。在更干净的同温层(距地表10公里),大约有20个粒子/升,在非常干净的海面上大约有2600个粒子/升。同一地区不同时间和陆地上的计数浓度差异较大。我国大气计数浓度大致可分为“工业城市”、“城市郊区”、“非工业地区或农村地区”,≥0.5 m的颗粒物浓度分别为1×106颗粒物/L、2×105颗粒物/L和3×105颗粒物/L。
  Atmospheric dust is the object that clean laboratory deals with directly. In cleaning technology, the most commonly used concentration is particle number ≥ 0.5m. In the cleanest stratosphere (10km from the surface), there are about 20 particles / L, and in the very clean sea, there are about 2600 particles / L. In the same area, the concentration of count varies greatly at different times and on land. The air counting concentration in China can be roughly divided into "industrial city", "urban suburb", "non industrial area or rural area". The concentration of particles ≥ 0.5m is 1 × 106 particles / L, 2 × 105 particles / L and 3 × 105 particles / L respectively.

  2. Internal pollution sources
  洁净实验室产生的灰尘量可以认为是由设备的局部排气排出,而不是流入洁净室。产品、材料等在搬运过程中产生的粉尘和人体粉尘,一般很小,可以忽略不计。由于目前清洁的室内装饰采用较好的金属墙板,来自建筑物表面的发尘量也很少,一般占10%以下,发尘主要来自人,占90%左右。
  The amount of dust produced in the clean laboratory can be considered to be discharged by the partial exhaust of the equipment, rather than flowing into the clean room. The dust and human dust generated in the process of handling products and materials are generally small and can be ignored. At present, the clean interior decoration adopts better metal wallboard, and the amount of dust from the building surface is also small, generally accounting for less than 10%, and the dust mainly comes from people, accounting for about 90%.
