100级管道式过滤结构洁净通道的研制

Class 100 clean tunnel with filter tube structure

一个１７ｍ２１００级洁净通道，采用专利管道式终末及中效过滤结构，装在通道顶上的１３台风机同时运转。在通道内离地１．２ｍ平面上，测定３９个点，每声、连续３次采样，整理得悬浮粒子总平均浓度：≥０．３μｍ０．４９个／Ｌ，≥０．５μｍ０．１３个／Ｌ，≥５μｍ０个／Ｌ。风机低速运转，平均风速０．６２ｍ／ｓ，平均Ａ声级噪声５５ｄＢ。１３台风机总配电机功率仅１．５６ｋＷ。

Describes a Class 100 clean tunnel with an ares of 17square metres, incorporating patented fi iter tubes in its structure.The clean tunnel was messured with 39 measuring points positioned sta height of 1.2 m above the floor throughout the tunnel.The totalaverage concentration of the airborne particles acqui red throughprocessing the continuous sampl ing results are 0.49,0.13 and 0 L- 1 forthe particles greater than 0.3,0.5 and 5 μm in size respectively. Thetunnel proved to be of low enersy consumption as its sl 1 13 fan motorsneed only 1. 56 kW in operation power.
