High quality industrial chemical oil heating reaction kettle
pressure vessel
Reactor is a kind of equipment to realize the reaction process,
which is widely used in chemical, oil refining, metallurgy and
other fields. The reactor is used to realize liquid-phase
single-phase reaction process and liquid-liquid, gas-liquid,
liquid-solid, gas-liquid-solid and other multiphase reaction
processes.
The types of commonly used reactors (see table) are: ① tubular
reactors. It is composed of empty tubes or filled tubes with large
length and diameter, which can be used to realize gas phase
reaction and liquid phase reaction. ② Kettle reactor. It is
composed of cylindrical vessels with small length-diameter ratio,
often equipped with mechanical stirring or air flow stirring
devices, and can be used in liquid-phase single-phase reaction
process and liquid-liquid, gas-liquid, gas-liquid-solid and other
multiphase reaction processes. The tank used for gas-liquid
reaction process is called bubbling stirred tank (see bubbling
reactor); The slurry reactor used for gas-liquid-solid reaction
process is called stirred tank slurry reactor. ③ Reactor with solid
particle bed. Gas or (and) liquid pass through fixed or moving
solid particle bed to realize multiphase reaction process,
including fixed bed reactor, fluidized bed reactor, moving bed
reactor, trickle bed reactor, etc. ④ Tower reactor. Tower equipment
used to realize gas-liquid or liquid-liquid phase reaction process,
including packed column, plate column, bubble column, etc. (see
color picture). ⑤ Jet reactor. It is a device that uses the
injector to mix and realize the gas-phase or liquid-phase
single-phase reaction process and the gas-liquid and liquid-liquid
equivalent multiphase reaction process. ⑥ Other non-typical
reactors. Such as rotary kiln, aeration tank, etc.
