Description
Technical field
The utility model belongs to fixed bed reactors technical field, particularly relates to a kind of fixed bed reactors with bendable reaction tube structure.
Background technology
Fixed bed reactors are also called packed bed reactor, are filled with solid catalyst or solid reactant in order to realize a kind of reactor of heterogeneous reaction process.Solids is usually in graininess, and particle diameter about 2 ~ 15mm, is piled into the bed of certain altitude (or thickness).Bed transfixion, fluid is reacted by bed.The difference of it and fluidized-bed reactor and moving-burden bed reactor is that solid particle remains static.Fixed bed reactors are mainly used in realizing gas-solid catalysis, as ammonia convertor, sulfur dioxide contact oxidation device, hydrocarbon steam converting furnace etc.During for gas-solid phase or liquid-solid phase uncatalyzed reaction, bed then loads solid reactant.Trickle bed reactor also can belong to fixed bed reactors, gas, liquid stream passes downwardly through bed, contacts in gas-liquid-solid.
During use, if exothermic heat of reaction is violent, the derivation of heat can be subject to the restriction of reaction tube heat transfer, thus reaction tube axially and footpath inwardly form larger thermograde, likely make catalyst because of hot-spot coking, side reaction increase, catalyst utilization declines.
