  烘干机设备废气风量大,含尘浓度高,水分大,露点高,易结露,排放点高,污染范围广,是除尘技术的难点。烘干机尾部废气与各厂工艺条件有关,个别企业用于多处材料的烘干,生产变化大,开停机频繁,波动范围大,再则,用煤作烘干热源,废气中的硫的氧化物对金属结构件有腐蚀作用,给除尘器的选用带来一定的困难。本文以下将介绍增加烘干机除尘器的寿命的四种措施。
  It is difficult to remove dust from dryer equipment because of its large exhaust air volume, high dust concentration, high moisture content, high dew point, easy condensation, high discharge point and wide pollution range. The tail exhaust gas of dryer is related to the technological conditions of various factories. Individual enterprises are used for drying many materials. The production changes greatly, the startup and shutdown are frequent, and the fluctuation range is wide. Furthermore, coal is used as the heat source for drying. The sulfur oxides in the exhaust gas have corrosive effect on the metal structure parts, which brings some difficulties to the selection of dust collectors. This paper will introduce four measures to increase the service life of the dust collector of the dryer.
  1.除尘设备的材质要选择铝含量不低于95%的合金,这样可以大大减少腐蚀。
  1. Material of dust removal equipment should choose alloy with aluminium content not less than 95%, which can greatly reduce corrosion.
  2.除尘系统的保温工作要做好,上面我们已经说过冷风的进入是造成除尘设备腐蚀的重要原因之一,只要保温工作做到位,腐蚀情况就会大大减少。

  2. The heat preservation work of dust removal system should be done well. As we have said above, the entry of cold air is one of the important reasons for the corrosion of dust removal equipment. As long as the heat preservation work is in place, the corrosion situation will be greatly reduced.
  3.可采用二级除尘方案。所谓二级除尘,就是先用耐磨高的旋风除尘器进行初步除尘,然后再用第二除尘器进行后除尘。
  3. Secondary dust removal scheme can be adopted. The so-called second-stage dust removal is to use a high wear-resistant cyclone dust collector for preliminary dust removal, and then use the second dust collector for final dust removal.
  4.烘干机和除尘器的操作一定要规范。规范的操作程序是所有机械设备的必须步骤,操作程序的规范可以大限度的减少腐蚀。
  4. The operation of dryer and dust collector must be standardized. Standardized operating procedures are the necessary steps for all mechanical equipment, which can minimize corrosion.
