Abstract
The invention discloses an anti-shake structure for tube bundles of a condenser. According to the invention, one or more auxiliary small partition plates are added between each two original partition plates; the dimensions of each auxiliary small partition plate are less than those of each corresponding original partition plate; an upper-end installation position of each auxiliary small partition plate is aligned with the upper ends of the corresponding original partition plates; and the auxiliary small partition plates are used for supporting heat exchange tubes on the upper part of the condenser. Spanning reduction is carried out on the tube bundles on the upper part, which are greatly influenced by a steam flow, and vibration of a unit and shake of the tube bundles can be controlled to be within a standard range, thus project cycle and expenses are saved.
Description
Technical field
The present invention relates to clammy condenser of thermal generator set apparatus field, particularly a kind of solution is due to the improper bank of condenser pipes trembled caused of tube bank span anti-quiver structure and method.
Background technology
The wet type cooling unit in current domestic thermal power plant, its condenser cooling tube when first installation mostly is copper pipe, and after the operation of about 10 ~ 15 years, the service life of copper pipe expires all, and the security risk that its heat exchanger tube breaks all is strengthening year by year.Replacing cooling tube is imperative.Along with the progress of material science, the cooling tube after replacing mostly is stainless steel.Calculate according to HEI, copper tube design span is about 1500mm, and stainless steel tube design span is about 750mm.Most power plant does not all change span after the transformation of condenser replace tubes, the stainless steel tube newly changed due to span excessive, do not meet the requirement of HEI, thus under the inner steam flow effect of condenser, the tube bank caused tremble aggravation phenomenon of common occurrence, tube breaking phenomenon also happens occasionally, and has a strong impact on unit safety operation.
Summary of the invention
The object of the present invention is to provide a kind of simple, save the project cycle, the anti-flutter reconstruction structure of bank of condenser pipes of cost saving and method.
To achieve these goals, technical scheme of the present invention is: the anti-structure of quivering of a kind of bank of condenser pipes, comprise septum primum plate, heat exchanger tube, auxiliary small baffle, it is characterized in that, auxiliary small baffle is positioned at septum primum plate between any two, small baffle between every two septum primum plates can be one or more, the size of accessory septa is less than septum primum board size, align with septum primum plate upper end in its installation site, upper end, auxiliary small baffle has the position of opening identical with septum primum plate and size, for through heat-exchanging tube bundle, supports the heat exchanger tube on condenser top.
Further, septum primum plate has an auxiliary small baffle between any two, center between the span between two septum primum plates.
Further, septum primum plate has multiple auxiliary small baffle between any two, divides equally and is positioned at septum primum plate span part.
Further, the height of auxiliary small baffle is the 1/5-1/10 of septum primum plate height, for supporting the top heat exchanger tube of 1/5-1/10.
Also provide a kind of bank of condenser pipes anti-method of quivering, after being applied to condenser retrofit replace tubes Bundle material with span is installed does not mate caused tube bank and tremble, it comprises,
Make auxiliary small baffle based on former bank of condenser pipes size, the size of auxiliary small baffle is less than septum primum board size, the through hole of processing position of opening identical with septum primum plate and size on auxiliary small baffle;
Between the span of septum primum plate, set up one or more small baffle, align with septum primum plate upper end in its installation site, upper end;
Pierce into heat-exchanging tube bundle by the through hole of septum primum plate and small baffle, small baffle is only for supporting the part heat exchanger tube near condenser upper entrance.
Further, the fixing and reinforcement of small baffle by carrying out reinforcement welding in adjacent housings.
Further, an auxiliary small baffle set up between any two by septum primum plate, center between the span between two septum primum plates.
Further, multiple auxiliary small baffle set up between any two by septum primum plate, divides equally and is positioned at septum primum plate span part.
Further, the height of auxiliary small baffle is the 1/5-1/10 of septum primum plate height, for supporting the top heat exchanger tube of 1/5-1/10.
Further, the height of auxiliary small baffle changes successively, and the height being positioned at the auxiliary small baffle of tube bank both sides is less, and the height being positioned at the auxiliary small baffle in tube bank centre position is larger.
The present invention is by between septum primum plate span, small baffle is installed for supporting condenser upper bundle, improve its rigidity, span reduction is carried out for affecting larger upper bundle by steam flow, unit vibrations and tube bank can be trembled all controls within critical field, save the project cycle, cost saving.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, the invention will be further described, should be appreciated that content described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
The present invention adopts " the small baffle supporting methods " mentioned, designs and produces some small baffles based on former bank of condenser pipes, and only some tube bank is through small baffle, in order to support condenser upper bundle.Fixing and the reinforcement of small baffle by carrying out reinforcement welding in adjacent housings.
As shown in Figure 1, the anti-structure of quivering of a kind of bank of condenser pipes, comprises tube sheet, heat exchanger tube, septum primum plate, auxiliary small baffle.Auxiliary small baffle is located between septum primum plate span between any two, can set up one or more auxiliary small baffle between any two as required at septum primum plate.As set up one, centre of span position can be located at, when setting up multiple auxiliary small baffle, divide equally septum primum plate span part.Auxiliary small baffle has the position of opening identical with septum primum plate and size, and for passing heat-exchanging tube bundle, the height of accessory septa is the 1/5-1/10 of septum primum plate height, aligns with septum primum plate upper end in its installation site, upper end, for supporting the top heat exchanger tube of 1/5-1/10.
Suffered by the heat exchanger tube close to condenser top, the impact of main steam turbine steam discharge steam flow is much larger than bottom heat exchanger tube, by adopting auxiliary small baffle to reduce span to the top heat exchanger tube of top 1/5-1/10, thus improve its rigidity, unit vibrations and tube bank can be trembled and all control within critical field.Concrete practice result is fairly good.
Further optimal enforcement, the height of auxiliary small baffle changes successively, and the height being positioned at the auxiliary small baffle of tube bank both sides is less, and the height being positioned at the auxiliary small baffle in tube bank centre position is larger.Further minimizing processing installation, improves anti-effect of quivering.
This technology is simple, can conveniently deal with problems, and saves the project cycle, cost saving.
Last it is noted that the foregoing is only explanation of the present invention, be not limited to the present invention, although to invention has been detailed description, for a person skilled in the art, it still can be modified to aforementioned described technical scheme, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
