Problems solved by technology
The defect of the support frame of the tube bundle in the traditional special heat exchanger is that: the structure with flow holes on the plate body, the plates other than the tube holes and the flow holes will hinder the flow of the powdery heat exchange medium, so the traditional The structure of the support frame is easy to cause blockage of the powder heat exchange medium, which makes it difficult for the special heat exchanger to work normally; in addition, this structure makes the flow area of the powder heat exchange medium smaller and the heat exchange effect is poor

Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0012] Such as figure 1 , figure 2 As shown, the support frame of the tube bundle in the special heat exchanger includes a central support tube 1, and the outside of the central support tube 1 is provided with a number of side support tubes 2 arranged in a ring around the center support tube 1, and the side support tubes 2 The number of circles on the outside of the central support tube 1 and the number of side support tubes 2 in each circle can be determined according to the diameter of the shell-side cylinder of the heat exchanger and the tube bundle of the heat exchange tubes. A connection plate 3 is fixedly connected between the adjacent side support tubes 2 in each circle, and a connection plate 3 is connected between the center support tube 1 and each side support tube 2 in the adjacent outer circle. Each of the side support...

The invention discloses a support frame for a tube bundle in a special heat exchanger, which comprises a central support tube, and on the outside of the central support tube are arranged a plurality of ring-shaped side support tubes arranged around the central support tube. A connection plate is fixedly connected between the side support tubes of the center support tube and each side support tube in the adjacent outer ring, and a connection plate is connected between each side support tube in each circle. The adjacent side support tubes in the outer ring are all fixedly connected with connection plates; the connection plates, central support tubes and side support tubes are all arranged along the flow direction of the powdery medium. The invention has the advantages of greatly increasing the flow rate of the powdery heat exchange medium, effectively preventing the powdery heat exchange medium from being obstructed and blocked in the shell-side cylinder, and providing guarantee for the normal operation of the special heat exchanger.
Description
technical field [0001] The invention relates to the technical field of special heat exchangers, in particular to a support frame for tube bundles in special heat exchangers. Background technique [0002] The heat exchange medium in the shell-side cylinder of the special heat exchanger is in the form of powder. The structure of the support frame of the tube bundle in the traditional special heat exchanger is: a plate body, on which there are several tube holes and flow holes, and the tube bundles are pierced. In the tube holes, the powdery heat exchange medium circulates through the flow holes. The defect of the support frame of the tube bundle in the traditional special heat exchanger is that: the structure with flow holes on the plate body, the plates other than the tube holes and the flow holes will hinder the flow of the powdery heat exchange medium, so the traditional The structure of the support frame is easy to cause blockage of the powder heat exchange medium, which ...
