经过小型常压和中压的单管和多管试验,研制成了两种导叶式旋风子,又分别进行了工业放大试验,总结出了设计方法,可供有关单位使用。 工业试验装置 在四川成都配气站上建有一套工业试验装置,工业试验用多管除尘器的结构示意见图1。筒径φ700毫米,与站上所用切流式除尘器一样。内装19根φ108/76毫米圆锥型或直筒型导叶式旋风子(叶片出口角β=30°),呈两圈同心圆均布排列,中心距为138～146毫米。叶片系单片精密铸造,用铜焊焊在芯管上,再将焊缝锉平。叶片外侧
After a small pressure and pressure in the single-tube and multi-tube test, developed two kinds of guide vane cyclone, respectively, were carried out industrial amplification test, summed up the design method for the use of the relevant units. Industrial test equipment Chengdu, Sichuan gas station has built a set of industrial test equipment, industrial test with a multi-tube structure shown in Figure 1. Tube diameter φ700 mm, and the same cut-off filter used on the station. Nineteen φ108 / 76mm conical or straight guide vane cyclones (leaf outlet angle β = 30 °) are arranged in two concentric circles with a center distance of 138-146 mm. Blade is a single piece of precision casting, brazing welded on the core tube, and then filing the weld. Outside of leaves
