Quasi-omni radially fixed bed reactor

The present invention relates to a quasi-omnidirectional radially fixed bed reactor, comprising a cylindrical body, provided with a central axis of the cylinder tube, the cylinder body is provided with a bleed air and 1-4 arranged vertically catalyst basket; basket in addition to the top catalyst the outer casing are made to rest radially catalyst bed, comprising a housing provided with a top axial-radial catalytic converter gas located between the axial section and a radial section of the following axial section, an axial and radial segments; from the barrel and the sequence comprises at least one radial bed for filling ruthenium ammonia synthesis catalyst, bed rest for filling the iron-based ammonia synthesis catalyst; bleed air through the bed in all radial loading of ruthenium based ammonia synthesis catalyst , a bleed air inlet is disposed above the all radial bed, the outlet provided at the bottom of the barrel. Simple structure of the present invention can improve the synthesis efficiency of the ammonia synthesis, lower operating pressure, reducing power consumption and economic efficiency.
