蚕茧缫丝厂的蒸汽锅炉是用于提供煮茧蒸汽的设备，一般缫丝厂的蒸汽锅炉属于中小型锅炉，很少进行余热回收，直接排放的尾气温度达到300-500℃，直接将剩余的尾气排放到室外，一方面热损失极大、不符合国家标准控制要求，另一方面，物料在锅炉燃烧后产生大量的粉尘，直接排放会造成环境污染。Steam boilers in cocoon reeling factories are used to provide cocoon cooking steam. Generally, steam boilers in silk reeling factories are small and medium-sized boilers, which rarely recover waste heat. The temperature of the exhaust gas directly discharged reaches 300-500°C, and the remaining The exhaust gas is discharged to the outside. On the one hand, the heat loss is huge and does not meet the national standard control requirements. On the other hand, the material generates a large amount of dust after the boiler is burned, and the direct discharge will cause environmental pollution.
另外，蚕茧缫丝厂会在生产中挑捡出次蚕茧，次蚕茧既是一种很好的肥料、饲料原料，蚕茧里面的蚕蛹也是一种价格昂贵的食材，然而次蚕茧受到蚕蛹死亡或者变质的影响，被污物、水汽沾湿，已经不适合直接用于肥料及饲料的生产，需要烘干后方可使用。现阶段用于蚕茧烘干机的种类较少，按热源形式分，主要分为“热风、微波、红外”几种类型，都需用电供应，效率较低、不节能环保。In addition, the cocoon reeling factory will pick out inferior silkworm cocoons during production. Secondary silkworm cocoons are not only a good fertilizer and feed material, but silkworm chrysalis inside silkworm cocoons are also an expensive food material. However, secondary silkworm cocoons are affected by the death or deterioration of silkworm chrysalis Affected by dirt and water vapor, it is no longer suitable for direct use in the production of fertilizers and feeds, and it needs to be dried before use. At present, there are few types of cocoon dryers. According to the form of heat source, they are mainly divided into "hot air, microwave, and infrared" types, all of which require electricity supply, which is low in efficiency and not energy-saving and environmentally friendly.

The residual heat enters the drum, and the drum is rotated at the same time to make the wet secondary cocoons heated evenly, so as to avoid excessive temperature, burning secondary cocoons and affecting the quality. The gas coming out of the drum contains most of the moisture, which is removed by the dehumidifier, which is beneficial to avoid the corrosion of the second fan after the moisture enters, and finally the moisture-removed flue gas is discharged into the atmosphere through the chimney.

由上表可知：以4t锅炉为例，一天所收集的热量，相当于450-550kg木柴所产生的热量，能烘干800-1000kg湿次蚕茧，待湿次蚕茧干后卖掉值800-1000元，可见使用本实用新型的烘干装置不仅节能减排，而且增加了企业的效益。It can be seen from the above table: taking a 4t boiler as an example, the heat collected in one day is equivalent to the heat generated by 450-550kg of firewood, which can dry 800-1000kg of wet silkworm cocoons, and the value of selling after the wet silkworm cocoons are dry is 800-1000 It can be seen that using the drying device of the utility model not only saves energy and reduces emissions, but also increases the benefits of the enterprise.
