以提高褐煤机和热源选择的效率的方式
影响原料水分含量褐煤烘干机烘干设备的结果是什么呢？为原料的特别高的水分含量，干燥也难以充分，因此干燥该原料后会湿润。不能满足生产要求。如水蒸气，水蒸气通过散热器加热干燥介质锅炉加热，这是间接加热的两倍，这样，总的热效率非常低，只有40％左右。间接加热的热空气洁净无尘，热效率60〜70％。其次，烘干机热源的选择。热源选择对于褐煤烘干机，根据燃料分为煤，石油，天然气，电力等根据传热条件点干燥器热源照常密钥可分为直接加热介质和间接加热干燥。和由油烟污染直接加热，影响了产品的质量，但使用良好的热，热效率是非常高的，褐煤干燥器来干燥的材料与少量的烟雾和没有影响的，可以是优选的。褐煤干燥过程中存在的问题，易产生异味，需要除尘脱臭处理，能耗大或加工费，干污泥波动的市场需求，市场缺乏的，也有可燃性粉尘防爆安全隐患和设备技术问题如的污泥干燥处理成本严重磨损高 设备材料：鉴于污泥和不可预知的变化的特点，没有人知道不锈钢可以解决一切问题。因为褐煤具有耐酸碱，耐腐蚀性，所以干燥器厂家优先设备经受的变化？机械设备工伤事故不在于是否能保证？以确保该设备本身能满足要求，并要求操作人员掌握的基本操作方法。然而，在干燥设备领域，铁的主要材料仍是有一定的技术，使理性的选择主要是成本，一些大型技术设备不能使用高金属材质，但这样会降低使用寿命，提高了投资成本。
The way to enhance the efficiency of the lignite dryer and heat source selection

Affect the outcome of lignite dryer drying equipment of raw material moisture content is what? For particularly high moisture content of raw material， a drying it is difficult to fully， therefore after drying the raw material will be moist. Can not meet the production requirements. Such as boiler heating of water vapor， vapor through the radiator heating drying medium， this is the indirect heating twice， this way， the total thermal efficiency is very low， only about 40%. Indirect heating hot air clean clean， thermal efficiency is 60 ~ 70%. Secondly， the dryer heat source selection. Heat source selection is the key for lignite dryer， dryer heat source as usual according to the fuel divided into coal， oil， gas， electricity， etc. According to heat transfer condition points can be divided into the medium directly heating and indirectly heating drying. And directly heated by soot pollution and affect the quality of the product， but use good heat， thermal efficiency is very high， lignite dryer to dry the material with a small amount of smoke and no effect， can be preferred. Lignite drying process there is a problem， easy to produce odor， need to dedust deodorization treatment， large energy consumption or processing fees， the market demand of dry sludge volatility， lack of market， there are combustible dust explosion safety hidden trouble and device technical problems， such as severe abrasion of sludge drying processing cost is high Equipment material: in view of the characteristics of the sludge and unpredictable change， no one was sure stainless steel can solve all problems. Because the lignite has acid and alkali， corrosion resistance， so the dryer manufacturers priority equipment withstand the changes? Mechanical equipment inductrial injury accident is not whether can guarantee? To ensure that the equipment itself to meet the requirements， and require operators to master the basic operation method. However， in the field of drying equipment， the main materials of iron is still a certain technology， make the choice of reason mainly is the cost， some large technical equipment can‘t afford to use the high metal material， but this will reduce the service life， improve the investment cost.
