硝化反应器的设计+CAD图纸+答辩PPT
搅拌釜式反应器由搅拌器和釜体组成。搅拌器包括传动装置，搅拌轴（含轴封），叶轮（搅拌桨）；釜体包括筒体，夹套和内件，盘管，导流筒等。工业上应用的搅拌釜式反应器有成百上千种，按反应物料的相态可分成均相反应器和非均相反应器两大类。非均相反应器包括固-液反应器，液-液反应器，气-液反应器和气-液-固三相反应器。

Design of Nitrifying Reactor
Abstract: Generally，the nitrifying process should happen in fluid phase in tank reactor. According to the differences of nitration agents and media，enamel still，FYG and stainless steel vessel are all available. In the process of mixed acid nitration，in order to keep the appropriate reaction temperature，jackets are used to remove a lot of heat，coiler is also used to increase heat transfer surface when it is necessary.
Stirred tank reactor by the stirrer and the reactor body. The agitator gear stirring shaft ( with shaft seal)，impeller，kettle body including a cylinder，jacket and coil，draft tube etc. Industrial application of stirred tank reactor，there are hundreds of homogeneous reaction and heterogeneous reactor can be pided into two major categories according to the phase of the reaction materials. The non - homogeneous reactor，including the solid - liquid reactor，liquid - liquid reactor，the gas - liquid reactor and gas - liquid - solid three-phase reaction device.
KeyWords: Reactor; Jacket; Coiler; Nitrifying Process; Agitator
