脱硫石膏烘干机对物料进行烘干不能满足要求

       近段时间，很多购买脱硫石膏烘干机的客户在咨询其对不同物料的烘干效果差别较大，而且不能满足要求的原因，下面郑州正科机械为大家做一些解疑：脱硫石膏烘干机烘干物料不能满足要求的原因有两点，******与物料的干湿程度有关，第二与热源的选择有关。高湿的物料，如果烘干不充分，烘干出来的物料就会略带潮湿，而热源的选择，也是很关键的。 热源的选择：作为脱硫石膏烘干机设备配套的热源设备很多，通常是按消耗的燃料来分类，有燃煤、燃油、燃气、电力等，按换热情况又可分为干燥介质直接加热和间接加热。譬如锅炉加热水形成水蒸汽，水蒸汽再通过散热器加热干燥介质，这就是两次间接加热，这种方式总的热效率很低，仅40％左右，在某些工厂生产中有多处用热点，为便于集中供热和管理，采用较多。燃煤热风炉有间接加热的和直接用燃烧烟气作干燥介质的（直火炉），间接加热的热空气清洁干净，热效率60～70％。 直接加热的因受烟尘的污染而影响产品质量，但热能利用很充分，热效率很高，对烘干时物料中混入少量烟尘而无影响时，可优先采用。油燃烧器目前也使用越来越多，具有操作简便、升温迅速、温度稳定、控制方便的优点，且使用成本较低。热源选择涉及到烘干设备的投资费用、热风温度、物料的烘干质量、烘干成本、环境保护、人员劳动强度、自动控制水平等。 因此，你需要根据实际情况，进行客观的分析，再选购脱硫石膏烘干机所需要配备的热源设备。
Desulfurization gypsum dryer for drying material can not meet the requirements Nearly period of time, a lot of desulfurization gypsum dryer customers buying in consulting a greater difference between the drying effect of different materials, and can not meet the requirements of the reason, the zhengzhou is secco machinery for everyone to do some disambiguation: desulfurization gypsum dryer to dry the material can not meet the requirements for two reasons, first is associated with the degree of dry and wet of material, the second is associated with the choice of heat source. High wet material, if insufficient drying, drying of material will be slightly damp, and the choice of heat source, is also very critical. The choice of heat source: as the desulfurization gypsum dryer equipment, a lot of heat source equipment usually are classified according to consumption of fuel, such as coal, oil, gas, electricity, according to the heat transfer and can be divided into the medium directly heating and indirectly heating drying. Such as boiler heating water to form water vapor and water vapor through the radiator heating drying medium, this is two indirect heating, this
