摘要：发酵罐是化工生产中实现化学反应的主要设备。其作用：①使物料混合均匀；②使气体在液相中很好分散；③使固体颗粒在液相中均匀悬浮；④使不均匀的另一液相均匀悬浮或充分乳化。目前已广泛地用于制药、精、酶制、食品行业等。它的主要组成部分包括釜体、搅拌装置、传热装置、轴封装置。还根据需要加其他的附件，如装焊人孔、手孔和各种接管(为了便于检修内件及加料、排料)，安装温度计、压力表、视镜、安全泄放装置(为了操作过程中有效地监视和控制物料的温度、压力)等。釜体是由简体和两个封头组成，它的作用是为物料进行化学反应提供一定的空间。搅拌装置是由传动装置，搅拌轴和搅拌器组成，它的作用是参加反应的各种物料均匀混合，使物料很好地接触而加速化学反应的进行。搅拌装置可以分为非潜水型(仅驱动机和减速机及传动系统露在液体外面和潜水型(从驱动机至搅拌器全部潜入液体内)两种类型。传热装置是在釜体内部设置蛇管或在釜体外部设置夹套，它的作用是使控制物料温度在反应所需要范围之内。

the design of stirred fermentor
Abstract：Fermentation is a chemical reaction to achieve the production of major equipment. Its role is: ①to mixed materials; ②the gas is well dispersed in the liquid phase; ③ making uniform solid particles suspended in liquid; ④making suspension or other liquid emulsified in uniform.For the uniform reaction, now is widely used in pharmaceutical, monosodium glutamate, enzyme system and food industries. Its main components include the reactor body, mixing equipment, heat transfer equipment and seal device. Also add other accessories needed, such as assembly and welding manhole, hand hole and all over (in pieces for ease of maintenance and feeding, nesting), install thermometers, pressure gauges, mirrors, safety relief device (for operation effectively monitor and control the material temperature, pressure) and so on. Mixing device is a gear, shaft and agitator stirring composition, its role is to participate in a variety of materials, reaction mixed evenly, so that good contact material to accelerate the chemical reaction. Mixing devices can be pided into non-ping type (only driven machines and gear and transmission system disclosed in the liquid outside and pe type (from the driving machine to sneak into a liquid blender all) types. Heat transfer device is set in the interior of reactor body coil or external tank set up in the jacket, its role is to control the materials needed in the reaction temperature range.
The design of the fermentation tank volume is 20 cubic meters, and this is a large tank design with coil heat transfer.
Key words: mixing tank；mixer；kettle body；heat transfer equipment；seal device；manhole.
