Temperature heating method of glass lined reactor

Glass lined reactors need temperature coordination during use, because most chemical reactions need to be carried out under certain temperature conditions, so we need to understand the heating method of the equipment temperature to ensure the normal use of the equipment.

　　 1. Water heating method of glass lined reactor

When the reaction temperature of the reactor is not high, we can use water heating for heating-this type of heating system has two types: open and closed: the open heating system is relatively simple, mainly composed of circulating pumps, water tanks and pipes And the regulator that controls the valve; and when high-pressure water is used, the reactor requires high mechanical strength, so a coiled tube must be welded on its outer surface. The gap between the coiled tube and the tank wall will increase the thermal resistance and reduce the heat transfer effect.

　　 2. Steam heating method of glass lined reactor

　　 If the equipment requires heating temperature below 100 degrees Celsius, it can be heated with steam below one atmospheric pressure; when the heating temperature is within the range of 100 to 180 degrees Celsius, saturated steam can be used; when the temperature is higher, high pressure superheated steam should be used.

　　3, other medium heating of glass lined reactor

If the process of the reaction medium in the reactor must be operated at high temperature or to avoid the use of high-pressure heating systems, other media can be used instead of water and steam, such as mineral oil (275~300°C), mixed with diphenyl ether ( Boiling point: 258℃), molten salt (140~540℃) and liquid lead (melting point: 327℃), etc.

　　 4. Electric heating method of glass lined reactor

　　The resistance wire is wound on the insulating layer of the whole body of the reactor or installed on a special insulator some distance away from the reactor, so a small space gap is formed between the resistance wire and the reactor body.

　　 Therefore, from a technological point of view, the glass lined reactor must be able to withstand pressure and temperature changes, so as to better improve equipment efficiency and service life.
