Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying the present invention are described in detail below with reference to the accompanying drawings.
Example 1
A combined arrangement type fluoroplastic heat exchanger suitable for a waste incineration power plant is shown in figure 1 and comprises a raw flue gas inlet 1, a raw flue gas outlet 2, a clean flue gas outlet 3, a clean flue gas inlet 4 and a header 5; a plurality of heat exchange tubes 51 arranged at intervals are arranged in the header 5, and the heat exchange tubes 51 are made of fluoroplastic. A tube pass inlet of the header 5 is connected with the raw flue gas inlet 1, and a tube pass outlet is connected with the raw flue gas outlet 2; the shell side import of header 5 with clean flue gas entry 4 is connected, shell side export with clean flue gas export 3 is connected, as shown the heat exchange tube 51 that is close to shell side import department in the header 5 is triangle-shaped staggered arrangement, triangle-shaped's summit is imported towards shell side, and the heat exchange tube 51 that wherein is triangle-shaped staggered arrangement includes the three rows at least, because flue gas treatment equipment is numerous in the waste incineration power plant, and the main flue gas pipeline is general not thick, and the inhomogeneity of import flow field impact is stronger, arranges through addding inlet section fluoroplastics pipe triangle-shaped staggered arrangement, shunts to both sides by triangle-shaped's summit when making the flue gas get into the shell side, does benefit to subsequent heat transfer.
