攪拌裝置可以分為非潛水型(僅驅動機和減速機及傳動系統露在液體外面和潛水型(從驅動機至攪拌器全部潛入液體內)兩種類型。傳熱裝置是在釜體內部設置蛇管或在釜體外部設置夾套,

摘要:發酵罐是化工生產中實現化學反應的主要設備。其作用:①使物料混合均勻;②使氣體在液相中很好分散;③使固體顆粒在液相中均勻懸浮;④使不均勻的另一液相均勻懸浮或充分乳化。目前已廣泛地用于制藥、味精、酶制、食品行業等。它的主要組成部分包括釜體、攪拌裝置、傳熱裝置、軸封裝置。還根據需要加其他的附件,如裝焊人孔、手孔和各種接管(為了便于檢修內件及加料、排料),安裝溫度計、壓力表、視鏡、安全泄放裝置(為了操作過程中有效地監視和控制物料的溫度、壓力)等。釜體是由簡體和兩個封頭組成,它的作用是為物料進行化學反應提供一定的空間。攪拌裝置是由傳動裝置,攪拌軸和攪拌器組成,它的作用是參加反應的各種物料均勻混合,使物料很好地接觸而加速化學反應的進行。攪拌裝置可以分為非潛水型(僅驅動機和減速機及傳動系統露在液體外面和潛水型(從驅動機至攪拌器全部潛入液體內)兩種類型。傳熱裝置是在釜體內部設置蛇管或在釜體外部設置夾套,它的作用是使控制物料溫度在反應所需要范圍之內。
本次發酵罐的設計容積是20立方米,屬于大型罐設計,采用蛇管傳熱。9570

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. 源¥自%六:維;論-文'網=www.mmeqir.tw
