Typically, the turbine back pressure of air-cooled condenser etc. limits (to limit erosion) by the maximum vapor (steam) velocity in pipe, and wherein vapor (steam) velocity increases along with the reduction of back pressure (due to steam proportion).So due to adding of pipe according to the present invention, so steam still remains on maximum admissible vapor (steam) velocity, and back pressure is lower.Another restriction that existing triangular pieces design causes is that the pressure in the exit of auxiliary tube tread assembly can not be lower than the ability of vacuum pump set.The pressure drop that this pressure is deducted in conduit by turbine back pressure usually deducts the pressure drop in pipe and draws.Therefore, because in pipe, pressure drop reduces, so lower according to the admissible turbine back pressure of the design of triangular pieces 160.
In addition, the design of above-mentioned tube bundle assembly also reduces the pressure drop in single triangular pieces 160.Such as, heat exchange coefficient is depended in the heat exchange occurred via triangular pieces 160, namely depends on the MTD between air and steam and exchange surface.Because pressure drop reduces, so higher according to the average pressure (mean value between inlet pressure and outlet pressure) in interchanger of the design of existing condenser arrangement 12 as previously mentioned.In other words, because steam is saturated, so average steam temperature is also higher for identical heat exchange surface, heat exchange is caused to increase.
Referring now to Figure 21, illustrate the delivery container being labeled as 210 in general manner.As its name implies, delivery container 210 is for being transported to job site by tube bundle assembly 30 from factory.As illustrated, condenser tube tread assembly 30 manufactures in factory and is assembled with corresponding steam manifold 204 and steam condensate collector 200.In delivery container, located five (5) individual tube bundle assemblies although illustrate, each container can optionally or demand and load and transport more or less independent tube bundle assembly.
Alternately, the tube bundle assembly that the above embodiment of the present invention manufactures and assembles before being used in shipment, it has steam manifold 204 and steam condensate collector 200, and the tube bundle assembly of alternate embodiment can not comprise manifold before shipment.More particularly, in such embodiments, tube bundle assembly can not have attachment steam manifold 204 thereon and load and transport.In the described embodiment, tube bundle assembly 30 can be assembled to form A type structure as described above at the scene.But substituting as use two steam manifold, this alternate embodiment can use single steam manifold, and wherein single steam manifold extends along " summit " that A constructs.
Referring now to Figure 22, show flow chart, schematically describe the number of assembling steps of Air flow condensing tower 12.As previously mentioned, before being shipped to job site, independent tube bundle assembly 30 is assembled, as shown in Reference numeral 212.Each independent tube bundle assembly 30 includes multiple finned tube 206 and steam manifold 204 and steam condensate collector 200.As above in conjunction with described by description and accompanying drawing before, as Reference numeral 42 identifies, before being placed in carrying containers 210 by independent tube bundle assembly 30, manufacture tube bundle assembly 30 in advance in factory.Then carrying containers 210 is transported to the on-the-spot place of erection.
Then, as Reference numeral 216 and Reference numeral 218 identify, the general triangular pieces represented by 160 of assembling at the scene.As previously mentioned, although tube bundle assembly can with any desired angle orientation, preferably it is departed from about 60 degree of horizontal direction (60 °) locate to the angle (x) of approximately seventy degrees (70 °) to depart from vertical direction about twenty degrees (20 °) to the angle (y) of about thirty degrees (30 °).More particularly, tube bundle assembly departs from vertical direction 26 degree (26 °) and departs from horizontal direction 64 degree (64 °) location.As indicated by reference numeral 220, single A type triangular pieces is illustrated as 160, and it forms " A " type by two tube bundle assemblies 30 and constructs.In this configuration, tube bundle assembly 30 self-sustained each other.
Referring now to the air-cooled condenser module 12 represented by Reference numeral 220, depict it and use five triangular pieces 160.As mentioned above, air-cooled condenser is the improvement of existing air-cooled condenser type and it has height " prefabricated " level, and it is equivalent to decrease installation cost and decrease the set-up time.Further, above-mentioned design reduces pressure drop, thus provides more efficient heat-exchange device.
