Title:
接触管束反応器に熱交換剤を輸送するためのポンプ
Document Type and Number:
Japanese Patent JP4149910
Kind Code:
B2
Abstract:
The invention relates to a pump ( 1 ) having a pump guide tube ( 13 ) for the transport of a heat-exchange medium ( 6 ) for a reactor having a bundle of catalyst tubes ( 2 ), where the pump ( 1 ) has a casing ( 14 ) which surrounds the pump guide tube ( 13 ), having an aperture ( 15 ) in the lower part of the casing ( 14 ) via which the heat-exchange medium ( 6 ) discharged from the lower region of the reactor by means of the pump ( 1 ) flows into the casing ( 14 ), flows upward in the region between the inner wall of the casing ( 14 ) and the outer wall of the pump guide tube ( 13 ), if desired via a heat exchanger ( 18 ), flows into the interior of the pump guide tube ( 13 ) via an aperture ( 16 ) in the upper region of the pump guide tube ( 13 ), flows through the pump guide tube ( 13 ) from top to bottom and flows via an aperture ( 17 ) in the lower region of the pump guide tube ( 13 ) into the reactor, into the upper region of the interspace between the catalyst tubes ( 2 ).
