Outer half tube reactor

1、 Overview of Outer Half Tube Reactor
The outer half tube reactor corresponds to the standard reactor, which uses a jacket as a heating and cooling device for heating and cooling. The outer half tube reactor is a reactor that uses a half tube as a heat exchange device for heat exchange reactions. The outer half tube reactor and jacket reactor each have their own advantages and disadvantages. The standard jacket reaction kettle has a large heat transfer area and good heat transfer effect, but it has an impact on the thickness of the inner wall of the tank due to the high steam pressure. As the thickness of the tank wall increases, the cost also increases, and the jacket with pressure belongs to pressure vessels. The outer half tube reactor has good strength, can withstand pressure, and does not belong to a pressure vessel when subjected to high pressure. The circular half tubes are welded along the tank wall for sufficient heat transfer and good diversion effect. However, the heat exchange area of the outer half tube reactor of the same size is small.
2、 Characteristics of the outer half tube reactor
The outer half tube reactor uses a loop of half tubes as the heat exchange jacket. Half tubes can be round or square, and both the bottom head and cylinder can be equipped with half tubes. The heat exchange area can be large or small, and can be set according to needs. Due to the circular shape of the outer half tube reactor, the heating is uniform, the flow guiding effect is good, and there will be no local overheating. The outer half of the reactor is equipped with an insulation layer, which has a beautiful and elegant appearance, and is clean without any dead corners. The mixing system inside the tank can be blade mixing, frame mixing, anchor mixing, push mixing, etc. according to the characteristics of the material. According to the process requirements, the tank can be equipped with feeding ports, feeding ports, online cleaning ports, SIP sterilization ports, reflux ports, steam inlets, condensate outlets, etc. According to the control requirements, an online temperature display and monitoring system, liquid level display, upper and lower liquid level control and alarm, weighing and metering, etc. can be configured.
