  干燥器的干燥能力与物料的湿润程度有关,并不是说任何物料都能在相同的时间内达到良好的干燥效果。这也和热源的选择有关。高湿物料,如果干燥不够,干燥出来的物料会有轻微的潮湿,而热源的选择,也是非常关键的。选择热源是非常重要的。有很多热源设备作为干燥设备的配套设备,通常根据所消耗的燃料进行分类,包括燃煤、燃油、燃气、电力等。根据热交换情况,可分为直接加热和间接加热干燥介质。例如,锅炉加热水形成蒸汽,然后蒸汽通过散热器加热干燥介质,这被称为间接加热两次。该方法的总热效率很低,只有40%左右。在一些工厂,有很多热点。
  The drying capacity of the dryer is related to the wetting degree of the material, which does not mean that any material can achieve good drying effect in the same time. This is also related to the choice of heat sources. High humidity materials, if not dry enough, dry out of the material will be slightly humid, and the choice of heat source, is also very critical. It is very important to choose the heat source. There are many heat source equipments as supporting equipment for drying equipment, usually classified according to the fuel consumed, including coal, fuel oil, gas, electricity and so on. According to the heat exchange, it can be divided into direct heating and indirect heating drying media. For example, the boiler heates water to form steam, which then heats the drying medium through the radiator, which is called indirect heating twice. The total thermal efficiency of this method is very low, only about 40%. In some factories, there are many hot spots.
  从工业环境保护的角度来看,烘干机对我国环境保护的可持续发展极为有利。在购买烘干机的过程中一定要了解自己的需要,如果设备功率不够,物料会出现干燥不理想,不能满足干燥要求。因此,在选择烘干机时,我们应该清楚地知道烘干机的输出量、物料的初始含水量、终含水量、计算出多少热能,然后计算出多少电耗等等。
  From the point of view of industrial environmental protection, dryer is very beneficial to the sustainable development of environmental protection in China. In the process of purchasing the dryer, we must understand our own needs. If the power of the equipment is not enough, the material will be unsatisfactory drying and can not meet the drying requirements. Therefore, when choosing the dryer, we should clearly know the output of the dryer, the initial moisture content of the material, the final moisture content, the calculated amount of heat energy, and then calculate how much power consumption and so on.

  在物料干燥过程中,利用燃料产生的热量对主机内部物料进行加热是一个重要步骤。物料干燥机的热量在工艺结束时通过设备的排风机进入主机,与物料进行热交换。加热工具是热风炉。热风炉与物料干燥机主机相互连接。热风炉的内部将镶嵌一层耐火砖。热风炉本身有三个小口,前两个是加燃料进去的(一般用煤),一个是拿出煤渣,后面是检修门,当检修门设计增大时,便于检修人员进入。
  In the process of material drying, using the heat generated by fuel to heat the material inside the main engine is an important step. At the end of the process, the heat of the material dryer enters the main engine through the exhaust fan of the equipment, and exchanges heat with the material. The heating tool is a hot blast stove. The hot blast stove is connected with the main machine of the material dryer. The interior of the stove will be inlaid with a layer of refractory bricks. Hot blast stove itself has three small openings, the first two are fueled in (generally coal), one is to take out the cinder, the latter is the repair door, when the design of the repair door increases, easy for maintenance personnel to enter.
  烘干机加热燃料可以是煤、天然气等,根据厂家自身的实际情况选择自己的燃料,前提还是要考虑生产成本,但比较常见的还是煤作为燃料。当物料通过流沙管进入主机时,在吸风机的作用下,热量进入主机并与物料进行热交换。经过设计和改进,热量可以与物料充分交换,更大程度的将热量传递到物料中,避免了大量热量的流失。这是一种直接有效的节省用户购买燃料成本和提高经济效益的方法。
  Dryer heating fuel can be coal, natural gas and so on, according to the actual situation of the manufacturers to choose their own fuel, the premise is to consider the production cost, but coal is more common as fuel. When the material enters the main engine through the quicksand pipe, under the action of the suction fan, the heat enters the main engine and exchanges with the material. Through design and improvement, heat can be fully exchanged with the material, and heat can be transferred to the material to a greater extent, avoiding the loss of a large amount of heat. This is a direct and effective way to save fuel costs and improve economic efficiency.
