Embodiment
Embodiment 1
As illustrated in fig. 1 and 2, pass partition is obliquely installed by the present invention by tube bank first, can when cooling medium flows through
Reduce impact dynamics of the cooling medium to pass partition, and the angle of inclination of pass partition is arranged in the range of 15~35 °, is made
Cooling medium impact dynamics be reduced to it is minimum, pass partition bottom installation T-shaped reinforcement, can strengthen its stability with
Impact resistance；Groove on pass partition can play a part of water conservancy diversion, can make cooling medium quickly through tube bank, with the second feed liquor
The medium that pipe flows into carries out heat exchange processing, and the depth of its further groove is 5~12 ㎜ so that cooling medium flow velocity reaches optimal；Pipe
Beam includes multiple heat-transfer pipes 1, fixed tube sheet 2 and floating tubesheet 3, and one end of heat-transfer pipe 1 is arranged on fixed tube sheet 2, heat-transfer pipe 1
The other end be connected with floating tubesheet 3, hook circle 4 and butterfly lid 5 be installed, hook circle 4 is logical with butterfly lid 5 on the floating tubesheet 3
Flange 8 is crossed to connect, in addition to the upper deflection plate 6 of multiple arch and lower deflection plate 10, between the upper deflection plate 6 and lower deflection plate 10
