Problems solved by technology

[0038] In particular, if the reaction chamber is operated at a pressure higher than that of the heating circuit, process fluids such as melamine and ammonia enter the heating circuit itself, overpressurizing the entire heating circuit and posing a risk of rupture

Embodiment Construction

[0061] According to the invention and with reference to Figure 4 with Figure 5 , the salient features common to both embodiments (1 and 1A) are first described.

[0062] According to the invention, the tube heat exchange modules 1 and 1A comprise a tube sheet (101) having: a first face 101a, which in use faces the interior of the heat exchange chamber 140; and a second face 101b, This second face is opposite to said first face 101a and in use faces outside said heat exchange chamber (140).

[0063] At least one through-hole 103 is produced in the tube plate 101 , which passes through the thickness of said tube plate 101 and opens into the opposite faces 101a and 101b. Advantageously, for the purposes highlighted above, the holes 103 are housed in sleeves 200 open at opposite ends and fixed to the tube sheet 101 .

[0064] Inside the sleeve 200 , preferably substantially coaxially, is housed the heat exchange tube 100 , which thus passes through the through hole 103 and ext...

Abstract

The present invention refers to a tube heat exchange assembly comprising a tube plate (101) that has a first face which, in use conditions, is facing inside a heat exchange chamber (140), and a secondface opposite to said first face and which, in use conditions, is facing outside said heat exchange chamber (140), at least one through hole (103) which passes through the thickness of said tube plate (101) and at least one heat exchange tube (100) which passes through said through hole (103) and is operatively associated with a supply circuit of a heat exchange fluid, wherein said tube heat exchange assembly further comprises at least one sleeve (200) opened at the opposite ends and fixed to said tube plate (101) and to said tube (100), said sleeve (200) being housed in said hole (103) and fitted on said tube (100) at a section of the latter wherein it crosses the thickness of the tube plate (101), wherein furthermore said sleeve (200) protrudes beyond said first face of the tube plate (101), so that a first open end of the same ends inside said heat exchange chamber (140); a further object of the invention is an apparatus comprising such a heat exchange assembly.

Description

[0001] This divisional application is based on the divisional application of the Chinese patent application with the application number 201510012289.3, the application date is January 9, 2015, and the invention title is "tubular heat exchange assembly and its heat exchange equipment". technical field [0002] The present invention relates to a tubular heat exchange assembly and a device comprising such a tubular heat exchange assembly. [0003] The plant notably comprises a chemical reactor, and more particularly comprises a chemical reactor for the production of melamine. Background technique [0004] Known according to overall reaction formula (1), melamine generates by urea pyrolysis: [0005] 6NH 2 CONH 2 →(CN) 3 (NH 2 ) 3 +6NH 3 +3CO 2 (1) [0006] Urea Melamine [0007] This reaction is known to be highly endothermic. [0008] The processes for converting urea to melamine are divided into two groups: those that perform urea pyrolysis at high pressure and tho...
