How to heat a second-hand reactor

The working temperature of the reactor is relatively high, and chemical reactions usually need to be carried out under certain temperature conditions, so the reactor is subjected to pressure and temperature at the same time. So, do you know what are the heating methods for second-hand reactors? Today, I will give you a detailed introduction, I hope it will be helpful to you.

1. Electric heating

The resistance wire is wound on the insulating layer of the reactor cylinder or installed on a special insulator at a certain distance from the reactor. Therefore, a small space gap is formed between the resistance wire and the reactor body.

2. Plumbing

It can be used when the temperature is not high, and its heating system is divided into two types: open type and closed type. The open type is simple. It consists of a circulating pump, a water tank, a pipeline, and a regulating valve regulator. When using high-pressure water, the equipment requires high mechanical strength. The surface of the reactor is welded with a serpentine tube. There is a gap between the serpentine tube and the wall The thermal resistance increases and the heat transfer effect decreases.

3. Steam heating

When the heating temperature is lower than 100℃, it can be heated by steam under one atmospheric pressure; in the range of 100～180℃, it can be heated by saturated steam; when the temperature is higher, it can be heated by high-pressure superheated steam.

4. Heating by other media

If the process must be carried out at high temperatures or avoid the use of high-pressure heating systems, other media can be used instead of water and steam, such as mineral oil (275~300℃), diphenyl ether mixture (boiling point 258℃), molten salt (140~540℃) ), liquid lead (melting point 327℃), etc.

The above content is a detailed introduction to the heating method of the second-hand reactor, I hope it will be helpful to everyone. If you want to know more about second-hand equipment, you might as well pay attention to jiuku.
