Application of Manhole Flange in Reactor


The reaction kettle is composed of a kettle cover, a cylinder body and a cylinder bottom. There is also a transmission and sealing device installed on the kettle cover to connect the stirring device. It is equipped with a manhole flange, a sight glass, a thermometer hole, a sample acquisition device and various connections. Coils for heat transfer are installed inside and outside the kettle, such as valves, and there are discharge valves and water separation devices at the bottom of the kettle.

The manhole flange generally uses hot oil to heat the reaction kettle. The outer part of the kettle body uses a smooth jacket or a spiral coil jacket, and the inside of the kettle uses an immersed heat exchange coil, also called a coil. In order to increase the heat transfer effect, some equipments have added heat transfer baffles. The material charged in the kettle must exceed the height of the outer jacket of the kettle and the coiled pipe in the kettle, so as to avoid overheating and coking of the material caused by "dry burning".

There are two functions of the stirring manhole flange, one is to fully mix, disperse and dissolve the materials involved in the reaction, to accelerate the reaction speed and the speed of dehydration, and the other to speed up the heat transfer speed and avoid overheating of materials close to the heating surface. Improve production efficiency and product quality The water separator installed at the bottom of the kettle is different from the water separator. The manhole flange is mainly composed of a sight glass, an on-off valve and a connecting pipe. Its purpose is to remove most of the water and impurities in the reactor, thereby improving the quality of the resin and reducing the loss of energy.
