Description
Technical field
The utility model relates to a kind of steam turbine auxiliary system equipment, specifically the steam baffle structure of the condenser steam chest in the steam turbine steam condensing system equipment.
Background technology
Steam turbine is that the thermal power transfer with steam is swinging prime mover of mechanical energy.Condenser is the key equipment in the steam turbine steam condensing system equipment, is the most important auxiliary equipment of steam turbine.The quality of its quality, performance, for the safety of guaranteeing steam turbine, economical operation, so that the heat-economy of whole steam turbine and operational reliability, tool is of great significance.In recent years, because the demand of steam turbine is increasing, add the scarcity of freshwater resources, the cooling medium of the auxiliary equipment condenser of the steam turbine that most of Coastal Power Station and industry drag all is devoted to adopt seawater.Because titanium has excellent sea water corrosion resistant, service life is longer, and specific strength is high, and good combination property is applied to Coastal Power Station and industry drags more and more with the condenser of titanium pipe and the manufacturing of titanium tube sheet.But condenser steam chest partial interior complex structure (seeing figure one), be divided into main condenser district and air cooling zone, be comprised of structures such as steam baffle, water fender, multithread orifice plate and reinforcement steel pipes, layering is installed between pipe, the dividing plate, welds together with pipe, dividing plate, the inner space is narrow and small, difficulty is installed, and welding capacity is large, especially the air setting district, the fitting operation difficulty very easily affects the heat exchanger tube of having put on during welding air setting district gas block panel.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of steam baffle structure of condenser steam chest air cooling zone is provided, and this steam baffle structure can not damage heat exchanger tube when welding, and has characteristics easy for installation, that welding is easy, simple in structure.
The technical solution adopted in the utility model is: a kind of steam baffle structure of condenser steam chest air cooling zone, comprise the first steam baffle and the second steam baffle that are welded between two central dividing plates, in a certain angle and be combined to form the air setting district of a sealing with condenser shell between described the first steam baffle and the second steam baffle; It is characterized in that: described steam baffle structure also comprises the blend stop of a font, two parallel edges of this blend stop are separately fixed on two central dividing plates, in described two steam baffles, the first steam baffle is fixed on the top of described blend stop, and the second steam baffle is fixed on the described blend stop.
Three hem width degree of the blend stop of described door font are 45-55mm.
Angle between described the first steam baffle and the second steam baffle is the 80-120 degree.
Installation process of the present utility model is: first the first steam baffle is welded on (position is identical with conventional condenser) between two central dividing plates, then weld door font blend stop (being arranged in the position of conventional condenser the second steam baffle welding), then carry out poling work, again with the second steam baffle joint welding on door font baffle plate, with main condenser district and air setting separate from.
The beneficial effects of the utility model are: because door font blend stop has certain width, when welding, can prevent that welding slag is splashed on the heat exchanger tube, and the existence of door font blend stop can not affect follow-up poling work, thereby the heat exchanger tube that solves conventional condenser damages problem, installation process is very convenient, and welding is also than being easier to, and structure is also relatively simple, with low cost, have preferably market value.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, conventional condenser comprises a condenser shell 9, and the inside of this condenser shell is separated out main condenser district 5 and air setting district 8 by one group of central dividing plate vertical with its axis 2.Air setting district between central dividing plate 2-2 is by the first steam baffle 6-1, the sealing chamber (the angle α between described the first steam baffle and the second steam baffle is the 80-120 degree) that the second steam baffle 6-2 and condenser shell 9 are combined to form, and not sealing of the air setting district between two ends tube sheet 1 and end dividing plate 2-1, leave gas passage 3, air in the condenser and incondensable gas travel back across bleeding point 7 by this passage polylith deflection plate 4 in the air setting district exactly, taken away by air-extractor again, with the vacuum of maintenance condenser and good heat transfer.
Main condenser district pipe 5-1 supports shockproof by central dividing plate, and air setting district pipe 8-1 is supported by a fairly large number of deflection plate 4, be subjected to the restriction of structure and technique, deflection plate and first gas block panel in necessary first welding equipment air setting district, refill and join air setting district pipe, last welding equipment the second steam baffle.Since the restriction of space stringing, the second steam baffle and heat exchanger tube close proximity (approximately 40mm), during welding equipment the second steam baffle, welding slag splashes and very easily hurts the first row pipe, causes the pipe subscription rate, and especially wall thickness only has the titanium pipe of 0.5mm.
Therefore, the steam baffle structure of a kind of condenser steam chest described in the utility model, the blend stop 10 of a font is set between two central dividing plates in air setting district, two parallel edges of this blend stop are welded on respectively (position is identical with the position of the second steam baffle in the conventional condenser) on two central dividing plates, in described two steam baffles, the first steam baffle is positioned at the top of described blend stop, the second steam baffle joint welding is on described blend stop, three hem width degree of blend stop are 45-55mm(recommend adoption 50mm, as shown in Figure 7), welding slag is splashed on the baffle plate, can not have influence on pipe.
