Original title Structure and working principle of reactor (reaction kettle) Source Coal Chemical Knowledge Base The reactor is a device for realizing a reaction process and is used for realizing a liquid-phase single-phase reaction process and a liquid-liquid gas-liquid liquid-solid gas-liquid-solid and other multiphase reaction processes Stirring devices (mechanical stirring airflow stirring etc) Are often nutsche filter dryer installed in the device When the ratio of height to diameter is large multiple layers of stirring blades can be used When the materials need to be heated or cooled in the reaction process a By structure 1 Tubular reactor Consists of a hollow tube or a filled tube with a large length-diameter ratio and can be used for realizing a gas-phase reaction and a liquid-phase reaction Expand 50l rotovap the full text Performance characteristics 1
Among them the stirred tank reactor centered in a vertical vessel is the most typical one Multi-stage series reaction kettle 4 III Tower Reactor Tower equipment for realizing gas-liquid phase or liquid-liquid phase reaction process including packed tower plate tower bubble tower etc jacketed glass reactor Bubble column reactor 1 Bubble column reactor is widely used in medium-speed slow-speed reactions and reactions with large heat release in which liquid phase also participates in the reaction For example the oxidation reaction of various organic compounds the chlorination reaction of various paraffins and aromatic hydrocarbons various biochemical reactions aeration oxidation of sewage treatment and carbonization of ammonia water to produce solid ammonium bicarbonate all use this bubble column reactor Packed column reactor 2 Packed column is a kind of mass transfer equipment in which the packing in the column is used as the contact member between gas and liquid The liquid is sprayed onto the packing from the top of the tower through the liquid distributor and flows down along the surface of the packing
