Background technology
The condensing plant that is used to cool off steam turbine or process waste gas uses with very large size for many years at energy technology field.In for example by the disclosed structure of DE-199 37 800 B4, ventilation blower is from following suction cooling air and with its heat exchange elements of pressing roof type to be provided with.The cooling air of heating upwards flows out.Below ventilation blower, must have enough free spaces, thereby ventilation blower for example stands upright on the bracing frame of supporting with 20 meters height.In this case, relate to a kind of steel construction of forming by column and the connecting rod that is connected column.Why needing connecting rod, is because column is quite elongated and do not having to reach unallowed vertical curved length under the situation of horizontal support.Connecting rod also is used for and will imports pedestal by wind and seimic horizontal force.
Fact proved that connecting rod be because the wind that flows into can produce vibration, and be under the relatively little wind conditions of 4-5m/sec.The length of connecting rod of this equipment surpasses 10m and is made by pipe or I section bar.
The width in ventilation blower district roughly is equivalent to length and for example is the length of connecting rod of 11-13m.The load that is absorbed by column on the angle in this ventilation blower district is quite big, amounts to 6 * 8 row's columns thereby must have on the condensing plant in 5 * 7 rectangle ventilation blower districts, just 48 root posts altogether.Each column need be connected with adjacent upright posts by connecting rod.The material input that is used for this bracing frame is very big.Mounting cost is also very high.
Summary of the invention
Set out thus, the objective of the invention is to, a kind of condensing plant with the described feature of claim 1 preamble is provided, this condensing plant can reduce the material input and reduce mounting cost aspect bracing frame.
This purpose is achieved on a kind of condensing plant with claim 1 feature.
The further structure that the present invention's design has advantage is the theme of dependent claims.
According on the condensing plant of the present invention, use a kind of supporting structure of brand-new type, wherein vertical column is fixed on the outside at the angle in ventilation blower district.This point can realize thus that is: at least one pillar has and vertically extending column in ventilation blower district and a plurality of apical support with respect to ventilation blower district and column inclination extension that are connected above column, described apical support is extended to the angle in ventilation blower district.Therefore the load that imports supporting structure from the angle does not directly derive vertically downward, but at first imports the apical support that tilts to extend, and the latter is bearing on the column of the lower vertical section that forms each pillar again.Each column absorbs the load at least two angles in ventilation blower district.In this manner, can obviously reduce the quantity of column.
For example, when arranging 2 * 3 ventilation blower districts, need 3 * 4=12 root pillar up to now.Pillar and respectively when four apical support that extend at four angles in ventilation blower district only separately at the center in ventilation blower district, amounting in this case only needs six roots of sensation pillar and therefore also only needs six pedestals.Also can reduce the connecting rod of desired level extension in the past by the quantity that reduces pillar.Also reduced mounting cost along with reducing Master Cost.Simultaneously have bigger free space available below the ventilation blower district, this helps to improve the inflow of air in ventilation blower.
For bearing load as far as possible equably, what conform with purpose is, column is arranged on the center in ventilation blower district, that is to say, is arranged on the place that diagonal intersects between two relative angles in ventilation blower district.In this configuration, 4 roots and tops of column support has identical length.But column also can be to a certain extent near shrinking in principle.In being provided with of 2 * 2 ventilation blower districts, for example it is contemplated that four root posts are fixed on the outside center in ventilation blower district separately, wherein, the relative distance of column can be dwindled or also can be strengthened, if wish near the center or the side bearing that keeps to the side.
In above-mentioned configuration, column is provided with at a certain distance with the side support or the vertical intermarginal of ventilation blower district at each angle that interconnects the ventilation blower district.But also it is contemplated that, single upright column be arranged on that ventilation blower district side supports below, and only have two at column and support under the situation of the apical support of extending to side respectively, column be arranged on that side supports below.Pillar is configured to Y shape to a certain extent in this case.Therefore this Y shape pillar itself is considered as swinging mounting and can only using down with the connecting each other of other pillars, so that make bracing frame generation necessary rigidity.If other pillars are provided with four apical support, preferably only use this Y shape pillar.
At least one angle in preferred ventilation blower district is by four apical support supportings.This means, this angle is the center that the ventilation blower district in 2 * 2 ventilation blower districts is provided with, wherein, each ventilation blower district is by a pillar supporting, its central post be arranged in the central area in ventilation blower district and wherein each column have respectively four apical support to four angles extensions in ventilation blower district.Support via four apical support at common angle by four ventilation blower districts, and just all apical support interconnect indirectly, and supporting structure obtains necessary rigidity.Particularly have on the large-scale condensing plant in 5 * 7 ventilation blower districts for example, support in the manner described above in the ventilation blower district of four angle sides at least separately, that is to say, is provided with four pillars, and they have four apical support respectively.
For reducing the vertical curved length of apical support, these apical support interconnect by connecting to support.Connection in the apical support zone is supported and is significantly shorter than two connecting rods between the adjacent upright posts.
In order to support level load, particularly wind-force load, column adjacent one another are interconnects by horizontal support.Horizontal support preferably can be extended between two adjacent columns diagonally.In this case, horizontal in principle support can just extend to beginning of apical support from the zone near pedestal always, and not influence the accessibility of the condensing plant below the ventilation blower district from the lower end of column.Principle to this is that column only adjacent one another are interconnects by horizontal support, and wherein, adjacent column typically is meant the column of four settings, by four ventilation blower districts in its supporting 2 * 2 specifications.
