Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the vertical syllogic U-tube high-pressure heater of just putting that this utility model is provided is described in detail.
Embodiment
nullWith reference to Fig. 1-Fig. 2，Just the putting vertical syllogic U-tube high-pressure heater it include it and includes housing 1 of the present embodiment、Tube bank 2 and hydroecium 3，Described hydroecium 3 is arranged on the top of housing 1，Hydroecium 3 includes hydroecium cylinder、Self sealss manhole、Fairing、Divide journey water feed apparatus 3-1、Feed-water inlet 3-2、Feedwater outlet 3-3、Top cover、Buckle bolt，Described feed water into、Export 180 DEG C of mirror image distributions，Described point of journey water feed apparatus 3-1 connects with feed-water inlet 3-2，Described tube bank 2 is U-tube，It is arranged on housing 1 internal，And be connected with hydroecium 3，Described U-tube heat transfer section is divided into superheated steam cooling section 4、Saturated vapor condensation segment 5、Hydrophobic cooling section 6 three sections，On described superheated steam cooling section 4 adopts、Bottom plate and involucrum 2-2 seal，Described housing 1 side is provided with steam inlet pipe 2-4，Steam inlet pipe 2-4 is provided with rustless steel unicast expansion joint 2-3，Rustless steel unicast expansion joint 2-3 and involucrum 2-2 connects，Described hydrophobic cooling section 6 includes hydrophobic side end plate 2-5、Hydrophobic room 2-6、Hydrophobic outlet 2-7、Rustless steel sleeve 2-8，Described hydrophobic outlet 2-7 is arranged on housing 1 side and is distributed with 180 DEG C of mirror images of described steam inlet pipe，Hydrophobic outlet 2-7 is connected with hydrophobic room 2-6 by rustless steel sleeve 2-8，Described hydrophobic room 2-6 is set to double-decker.
The cross section of described point of journey water feed apparatus 3-1 is arch, and arch circular arc and string intersection are provided with fillet.
Feeding water and entered a point journey water feed apparatus 3-1 by feed-water inlet 3-2, the heat exchanger tube being then dispensed in tube bank 2 carries out heat exchange.Owing to feeding water, the velocity ratio flowing to hydroecium is higher, and septum primum plate and hydroecium cylinder directly weld, and feed water direct impacting clapboard, form whirlpool, wash away dividing plate particularly weld seam, cause weld cracking, for improving this situation, a point journey water feed apparatus 3-1 is set at feed-water inlet place, cancels the former pass partition being directly welded in hydroecium, described point of journey water feed apparatus is for flexibly connecting, cross section is arch, and arch circular arc and string intersection are provided with fillet, connects without right angle, avoid water slug dividing plate, cause turbulent flow.
Superheated steam cooling section 4 adopts upper head plate 2-1, bottom plate 2-9 and involucrum 2-2 to seal, and superheated steam is introduced into this region, becomes micro-superheated steam after cooling.Connecting for avoiding high-temperature heat expansion to cause weld cracking, steam inlet pipe 2-4 to arrange rustless steel unicast expansion joint 2-3 and involucrum 2-2, steam fully enters superheated steam cooling section 4, utilizes the heat of steam to greatest extent, improves the efficiency of high-pressure heater.After superheated steam cooling becomes saturated vapor, enter saturated vapor condensation segment 5 and proceed heat exchange, eventually become saturation water, saturation water enters hydrophobic cooling section 6 and continues cooling, continuing heat exchange with the water in heat exchanger tube, finally cooling becomes supercool hydrophobic, hydrophobic outlet 2-7 discharge.
