At present, domestic use is more become with steam turbine the top admission formula condenser of arranging up and down, the normal arrangement structure of its tube bank be generally steam flow to following formula, steam flow upper quadrant and steam flow to three kinds of steam flow forms of side formula.Wherein, steam flow is to the following formula structure, and steam flow is the cooling tube bundle (be arranged in parallel form by thousands of cooling tubes) of from top to bottom flowing through basically.Because exhaust steam will be through a large amount of (almost whole) cooling tubes before arriving bleeding point, flow path is longer, therefore forms very big vapour locking.This is a kind of more old-fashioned structure, only is used for some small-power units.Steam flow upper quadrant structure, bleeding point is positioned at condenser top, and the direction of steam flow is to flow through cooling tube bundle from bottom to top.Turn to when flowing at steam flow, the contained part water droplet in the steam discharge can alleviate initial a few row's cooling tube and suffer the erosion of water droplet owing to action of centrifugal force is separated.Its major defect is that vapour locking is too big, has therefore limited being extensive use of of it.Steam flow more often adopts at conventional top admission formula condenser to side formula structure.Its bleeding point is arranged in the condenser both sides; Be more sparse ventrad arrangement with the cooling tube that steam discharge at first contacts, all the other cooling tubes then are arranged in the tortuous band shape of being made up of 7～～8 array of pipes.Owing to the tortuous banded steam inside passage that forms is convenient to entering of steam, therefore to compare to following formula with steam flow upper quadrant or steam flow, vapour locking is less relatively.Yet vapour locking still has the needs of further reduction.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, the improvement that provides a kind of side direction condenser to bleed structure, and it is less that this structure should have vapour locking, and the characteristics that condensing water temperature is higher are to improve the equipment runnability.
The utility model proposes following technical scheme:
The side direction condenser structure of entad bleeding, the one group of cooling tube that comprises the condenser shell that is shaped on vapor inlet port, installs in condenser shell inner chamber level, all cooling tubes parallel mutually and at interval a determining deviation be formed up to few cooling tube bundle district, the two ends of all cooling tubes extend in the hydroecium at condenser two ends respectively and each is tightly connected with a tube sheet, the periphery of tube sheet then with the tube wall sealing and fixing of hydroecium cylindrical shell so that cooling water absorbs the steam heat the condenser shell inner chamber when flowing through in cooling tube; It is characterized in that each cooling tube bundle district center is provided with an exhaust tube of deriving residual gas, this exhaust tube is parallel with cooling tube and by the steam chest membrane support, exit is fixed on the described tube sheet; The sealing of one end of exhaust tube and the other end cause the outside of condenser by pipeline, are shaped on equally distributed several aspirating holes on the periphery of exhaust tube.
In the described cooling tube bundle district, to the segment distance the exhaust tube of cooling tube bundle district central authorities, the spacing between the cooling tube reduces gradually from the edge in cooling tube bundle district; So that the steam in the housing inner chamber is passing through gap between the cooling tube, losing heat condense and fall to being removed in the flow process of the aspirating hole of cooling tube bundle central authorities, residual gas is discharged from described bleeding point.
Described cooling tube bottom is being provided with the hot well of collecting condensate water.
The beneficial effects of the utility model are: because the bleeding point of incoagulability gas is arranged on the core of cooling tube bundle; During work, steam is by the aspirating hole that flows to the center around the tube bank, not only stroke is shorter, and steam from around enter tube bank and the time have bigger aisle spare, vapour locking is reduced greatly, therefore compare to side formula tube bank layout, have littler vapour locking with steam flow, the work better effects if of condenser, the equipment runnability also significantly improves.In addition, this structure is when work, and steam can not only directly contact with the condensate water in the hot well of bottom and carry out backheat; And, after the little water droplet that condenses falls to leaving tube bank, must pass this steam backheat district owing to there being bigger space---steam backheat district around the steam flow radial inflow tube bank and between inner walls, could arrive hot well; In the process that the little water droplet that condenses falls in this zone, steam carries out the convection current backheat to little water droplet.Like this, twice backheat of condensate water by steam, its temperature equal or near saturation temperature; Therefore compare to side formula tube bank layout with steam flow, condensate water has littler degree of supercooling, has higher heat economy benefit.
