Zibo Shengpu Chemical Equipment Co., Ltd. gives you a detailed introduction to the information about the four heating methods of enamel reaction tank http:// obtaining high temperature.
Let's go!
1. Electric heating: the electric resistance wire is wound on the insulating layer of the reaction vessel body or installed on a special insulator at a certain distance from the reaction kettle. Therefore, the resistance wire and the reaction kettle are
There is a small space gap between the bodies.
2. Water heating: It can be used when the temperature is not high. The heating system has two types: open type and closed type. The open type is simpler, it consists of a circulation pump, a sink, a pipe and a control valve.
The regulator of the door is composed of high-pressure water, the mechanical strength of the equipment is high, the outer surface of the reactor is welded with a snake tube, and the coil has a gap with the wall of the kettle to increase the thermal resistance and heat transfer effect.
reduce.
3. Heating with other media: If the process requires high temperature operation or to avoid the use of high pressure heating systems, other media can be used instead of water and steam, such as minerals.
Oil (275 to 300 ° C), a diphenyl ether mixture (boiling point: 258 ° C), molten salt (140 to 540 ° C), liquid lead (melting point 327 ° C), and the like.
4, steam heating: heating temperature below 100 ° C, can be heated with a vapor below atmospheric pressure; 100 ~ 180 ° C range, with saturated steam; when the temperature is higher
High pressure superheated steam can be used.
