DN1300湍球塔设计
摘要
这几年来，除尘设备不断发展，湍球塔作为其中一员也有它自己的历程。在湍球塔中填料处于流化状态，这是湍球塔在气液传质设备当中应用了流化床的原理。湍球塔有很多的特点，比如它处理废气能力比较大，当然它的气体流速也是相当的高，气体和液体在塔内的遍布也是比较均匀的，并且塔的结构也是很合理的，这样就不会发生粘性物料堵塞的现象。但因为球的湍动会在每一段有一定程度的返混，所以用于塔板数不多的情况。并且由于湍球塔里面的小球大多数情况下是用塑料作为材料制造而成，所以在太高的操作温度下小球会不可控的老化变形。
本次设计湍球塔，在老师的指导和室友的相互照应下先是去图书馆借了充足的除尘设备的书籍，通过学习弄明白湍球塔的工作原理和大致情况，确定主体结构和零部件结构的设计，对载荷、强度进行计算和验算，以达到设计标准，并要绘制湍球塔相关的图纸，给出设计要求。在设计过程不仅要着眼于标准数据，还要考虑外来因素和自然因素，使设计符合相关标准、安全和制造等各方面的要求。

ABSTRACT
In recentyears, dust removal equipment has been developing, and the turbulent tower has its own course as one of them. The packed material in the turbulent sphere tower is fluidized,which is the principle of the fluidized bed used in the gas liquid mass transfer equipment. The turbulent sphere tower has many characteristics. For example, it has a relatively large capacity to dealwith exhaust gas. Of course, its gas flow rate is also quite high, and the gas and liquid flow in the tower are also relatively uniform, and the structure of the tower is alsovery reasonable. In thisway, the phenomenon ofviscous material blockagewill not occur. However, because the turbulence of the ball has a certain degree of backmixing in each section, it is used in the case of few trays. And because of the turbulence inside the tower, Most of the pellets are made of plastic, so the ball can deform uncontrollably at too high operating temperatures.
The design of the turbulent sphere tower，Under the guidance of the teacher, he firstwent to the library to borrow enough books.，To understand theworking principle and general situation of the turbulent ball tower by learning，To determine the design of the main structure and the structure of the parts, to calculate and check the load and strength in order to reach the design standard,And to draw the turbulence tower related drawings, give the design requirements.In the design process,we should not only focus on standard data, but also consider external factors and natural factors.Make design conform to relevant standards, safety and manufacturing requirements.
