Described venting port is preferably more than 4, axially is provided with symmetrically.
Described venting port preferably is arranged at the upper end of heat exchanging segment.
The upper end of tank body heat exchanging segment also is provided with the water of condensation water-in.
Further improvement of the utility model is, described reactor heat exchanging segment also is provided with internal circulation apparatus, described internal circulation apparatus is the circulation mouth of a river, upper end and the circulation mouth of a river of offering respectively in the top and bottom of heat exchanging segment cylindrical shell outer side wall, lower end, and be arranged at tank body outer, be connected in circulation tube between the upper and lower end circulation mouth of a river.
Described internal circulation apparatus can axially be provided with symmetrically for more than one group.
Of the present utility model further the improvement is that described tank body heat exchanging segment upper end inner side-wall is provided with the dividing plate that separates inside and outside the tank body heat exchanging segment upper end.The water of condensation water-in and the circulation mouth of a river, upper end are arranged between dividing plate and the heat exchanging segment inner side-wall.
It is planar that described dividing plate preferably is revolution.
Described dividing plate preferably is fixed in the form setting of heat exchanging segment inner side-wall with the lower end.
Owing to be provided with circulation device; can make water coolant descending; carry out the cold and hot water circulation; heat is taken out of; venting port can be discharged the steam that produces in the heat exchanging segment as early as possible simultaneously, and the steam that reduces in the chuck is detained, and this structure can solve the cavitation of tube sheet preferably; protect tube sheet, prolong the life-span of tube sheet.
