概述：

随着社会经济和城市化的发展，城市及工业污水的产生及其数量在不断增长，固废是污水处理后的副产品，是一种由有机残片、细菌菌体、无机颗粒、胶体等组成的极其复杂的非均质体，同时污泥中含有大量的有机物、腐殖质等可利用资源，对固废进行前期处理后，可作为焚烧介质、肥料、建筑材料、活性炭等。对于工业固废、生活固废过去一般采用填埋法进行处理。随着固废的量越来越大，人们开始使用焚烧法，这种方法可以从固废中有效地获取热能，减少环保成本并且不造成二次污染。另外，固废也可作为有机肥料进行深加工利用，但上述两种处理方法仍需对固废进行干化或半干化处理。大量固废产生，传统的空心浆叶干燥机已无法满足其烘干要求我们公司从国外引进*技术，采用圆盘式固废干化机对多种物料进行干化作业，采用不同形式的干化试验，进行技术与能耗的经济分析，总结出圆盘式固废烘干机是比较理想的节能干化设备。我公司对固废干化进行了多次升级换代和改型，形成我公司专有的技术及特点，以应对大型固废干化项目。

With the development of social economy and urbanization, the production and quantity of urban and industrial sewage are increasing. Solid waste is a by-product of sewage treatment. lt is an extremely complex heterogeneous body composed of organic debris, bacteria, inorganic particles, colloids and so on. At the same time, sludge contains a lot of organic matter and humus. lt can be used as incineration medium, fertilizer, building materials, activated carbon and so on. For industrial solid waste and life solid waste, landfil disposal was generally used in the past, With the increasing amount of solid waste. people bean to use incineration method, which can effectively obtain heat energy from solid waste, reduce environmentalcosts and do not cause secondary pollution,ln addition, solid waste can be further processed and utilized as oraanic fertilizer, but the above two methods still need to be dried or semi-dried, A large number of solid waste has been produced, and the traditional holow paddle dryer has been unable to meet its dryin requirements. Our company imports advanced technoloay from abroad, uses disc solid waste drver to drv various materials uses diferent forms of drying tests, carries out economic analysis of technology and energy consumption, and concludes that disc solid waste dryer is an ideal energy-saving drving equipment. Our company has uparaded and reformed the solid waste drying many times, forming our company's proprietary technology and characteristics, in order to cope with large-scale solid waste drying projects.

原理：

干化机主要由夹套，单轴转子和传动装置组成。固废通过夹套，空心轴和轴上焊接的空心盘片的热传到被间接加热干化。盘片对固废没有切割，而是通过盘片边缘的推进搅拌器的作用，对固废进行搅拌，不断更新干化面，从而实现干化的目的。

The drying machine is mainly composed of jacket, single shaft rotor and transmission device. The solid waste passes throughthe iacket, hollow shaft and heat transfer from the hollow disc welded to the shat to be indirectly heated and dried. The disc does not cut solid waste, but mixes solid waste by pushing the agitator on the edge of the disc, and constantly updates the drying surface, so as to achieve the purpose of drying.

特点：

1.采用蒸汽传热介质，既可用于半干化工艺也可用于全干化工艺，系统简单，辅助设备少。
2.设置空气补给口，使尾气排放更加顺畅，尾气处理系统负荷小。
3.可靠性高，持续运行性好，可昼夜运转，适用于长时间大处理量的固废干化。
4.蒸汽与固废不接触，尾气中不溶性气体量少，可以入炉焚烧，二次污染少。
5.运行时氧含量，温度和粉尘浓度低，系统安全性好。
6.千化机通过外壳壁、中空轴及每个竖立圆盘的左右两面进行传热，传热面积大，结构紧凑，外形尺寸小。
7.千化机内部，固废为湿固废，为防止固废粘结在转盘上，在外壳内警有固定的较长刮刀，伸到圆盘之间的空隙
起到搅拌固废，清洁盘面的作用。固废经破碎和搅动后，呈均匀颗粒状，有利于进一步处置。
8.采用低温热源(s170C)加热，圆盘上的固废在停车时不会过热，再次启动不受影响。
9.固废处理负荷大，即使进料不均匀也能保证平稳运行，内部运行阻力小，设备能耗低。
10.保养简单，持续运行性好，可昼夜运转，保证每年8000小时运行。

1. The steam heat transfer medium can be used in both semi-drying and full-drying processes. The system is simple and the auxiliary equipment is few.
2, the air supply port is set up to make the exhaust emission more smoother and the tal gas treatment system less load.
3. lt has high reliability, good sustainability and can operate day and night. lt is suitable for solid waste drying with long time andlarge capacity.
4. Steam is not in contact with solid waste, and the amount of insoluble gases in tail gas is less, so it can be incinerated in the furnace with less secondary pollution.
5. the oxygen content, temperature and dust concentration at runtime are low and the system is safe.
6, The drver conducis heat transfer throuah the shel wall. hollow shaft and the left and right sides of each vertical disc,The dryer has large heat transfer area, compact structure and small size.
7. In the dryer, solid waste is wet solid waste. In order o prevent solid waste from adhering to the turntable, there is a fixed ong scraper on the inner wall of the outer shell, which extends to the gap between the discs and plays the role of stiring solid waste and cleaning the disc surface. Ater solid crushing and agitation, the solid waste is uniform and granular, whicr is conducive to further disposal. , The solid waste on the disc will not overheat during parking and the restart will not be affected when heated by a lov temperature heat source (<170 C).
9. Solid waste treatment load is large, even if the feed is not uniform, it can ensure smooth operation, internal operation resistance is small, equipment energy consumption is low.
10. maintenance is simple, continuous operation is good, can run around the clock, ensure 8000 hours per year.
