Abstract
本实用新型公开一种汽轮机冷凝装置，包括冷凝器(2)和与其连接的热水井(3)及抽气器(4)，其特征在于：在冷凝器侧壁(2)与热水井(3)侧壁之间固定连接排气导管(5)。排气导管(5)将聚集在热水井内(3)的空气连续不断的及时排除，达到保持热水井(3)液位稳定，液位自动控制系统工作正常的目的，使汽轮机组安全、正常运行。
The utility model discloses a steam turbine condensing device, which comprises a condenser (2), a hot water well (3) and an air extractor (4) connected thereto, and is characterized in that: the condenser side wall (2) and the hot water well (3) The exhaust duct (5) is fixedly connected between the side walls. The exhaust duct (5) continuously removes the air accumulated in the hot water well (3) in time, so as to keep the liquid level of the hot water well (3) stable and the automatic liquid level control system to work normally, so that the steam turbine unit is safe and normal operation.
Description
Technical field
The utility model relates to a kind of steam turbine, relates in particular to a kind of steam turbine condensation device.
Background technique
Steam turbine is the thermodynamic cycle equipment that the thermal power transfer of steam is become mechanical energy, and it can drive other rotating machinerys such as generator, water pump.Steam becomes exhaust steam after doing work in steam turbine.Exhaust steam enters the condenser that is in vacuum state by steam-expelling port, enters hot well after the water quench in the device that is condensed in the copper pipe becomes water of condensation.Water of condensation is reclaimed again by condensate pump and utilizes.
Condenser and hot well are referred to as the condensation device of steam turbine, and it is the steam turbine indispensable visual plant that does work.The effect of steam turbine condenser hot well is to compile the condensed water that the back that is cooled forms, and keeps certain water level in hot well, makes condenser form high vacuum, keeps steam turbine and normally moves.
Hot well is equipped with magnetic force turn over board type level meter, shows liquid level in the hot well, and level meter is carried the 4-20mmA current signal according to the liquid level height to control system simultaneously, in order to automatic control water level at a certain numerical value.
For setting up cyclic process, need before the unit starting successively outside condenser is mended, to supply water, and this moment, condenser was an atmospheric pressure state that moisturizing point is on hot well top, air in the condenser hot well is subjected to top to come the drag effects of water to discharge at this moment, and gas is assembled the formation vent plug in hot well.Because the influence of vent plug, the inaccurate and fluctuation of the liquid level that magnetic force turn over board type level meter is shown causes the liquid level automatic regulating system malfunctioning, influences steam turbine and normally moves.
The model utility content
In order to overcome above-mentioned defective, technical problem to be solved in the utility model is to provide a kind of gas in the hot well is in time discharged to keep the steam turbine condensation device of hot well level stability.
The utility model is achieved in that fixedlys connected exhaust manifolds between condenser sidewall and hot well sidewall.
Because condenser is furnished with air ejector, air that can be at any time that it is inner is extracted out to keep vacuum state, between condenser and hot well body, exhaust manifolds are installed, with the venting gas appliance of air that accumulates in the hot well by designing, continuously in time get rid of, reach maintenance hot well level stability, the normal purpose of automatic control of liquid system works makes steam turbine set safety, normal operation.
Description of drawings
Fig. 1 is the utility model figure steam turbine condensation device structural representation;
Wherein, 1-steam turbine, 2-condenser, 3-hot well, 4-air ejector, 5-exhaust manifolds.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, between condenser 2 and hot well 3, fixedly connected exhaust manifolds 5, exhaust manifolds 5 two ends are fixedly linked with the sidewall of condenser 2 and hot well 3 respectively, exhaust manifolds 5 are steel pipe, diameter is greatly about about 30mm, one end is connected the middle part of condenser 2, and the other end is connected the liquid level top of hot well 3.The gas that leans on condenser 2 interior negative pressure will accumulate in 3 li of hot wells like this sucks condenser 2 continuously, by air ejector 4 air is extracted out and is entered atmosphere.
Claims (3)
1, a kind of steam turbine condensation device comprises condenser (2) and connected hot well (3) and air ejector (4), it is characterized in that: fixedly connected exhaust manifolds (5) between condenser (2) sidewall and hot well (3) sidewall.
2, a kind of steam turbine condensation device according to claim 1 is characterized in that: exhaust manifolds (5) one ends are connected the middle part of condenser (2), and the other end is connected the liquid level top of hot well (3).
3, a kind of steam turbine condensation device according to claim 1, it is characterized in that: the diameter of described exhaust manifolds (5) is 28mm～34mm.
