Description
Technical field
The present invention relates to turbine condenser technical field, specially a kind of horizontal turbine condenser.
Background technique
Steam turbine is also referred to as steam turbine engine, is a kind of rotary steam power device, and high temperature and high pressure steam passes through solid
Nozzle is determined as being ejected on blade after the air-flow accelerated, makes the rotor rotation equipped with blade row, while external acting.Steam turbine
It is the capital equipment of modern thermal power plant, is also used for metallurgical industry, chemical industry, in ship's powerplant.It is motor-driven in steamer
In power device, condenser is very crucial component part, and effect is the steam discharge of steam turbine to be condensed into water, therefore be also known as multiple
Hydrophone.
By the difference of steam condensation mode, condenser can be divided into surface-type (also referred to as dividing wall type) and hybrid (also referred to as contact
Formula) two classes.In surface condenser, the steam separated with cooling medium (usually metal pipe) on cooling wall is cold
Congeal into liquid.Cooling medium can be water or air, water-cooled surfaces formula condenser by the type of flow of cooling water be divided into single process,
Two kinds of double-flow.In direct-contact type condenser, steam is that liquid is condensed into the case where mixing with cooling medium, cold
Solidifying steam both can be water vapour, can also be the steam of other substances.Wherein use water as the surface condenser of cooling working medium,
Since the ratio of heat transfer coefficient air of water is big, the condensed water that high vacuum and acquisition cleaning are maintained in condenser, therefore state can guarantee
Mainly take this condenser in inside and outside thermal power plant.
However turbine condenser in the prior art has many flaws in actual use, such as:
Currently, being horizontally installed with stainless steel tube bank in the surface condenser that steam turbine generallys use, stainless steel tube bank is
Circular tube shaped, outer wall carries out condensation collection to the steam in steam, but the droplet of upper layer cooling water pipe outer wall condensation is often
It freely drips in the hot well for being collected to condenser bottom, during droplet drippage, outside the cooling tube that often drops down onto lower layer
Wall carries out secondary cooling, easily causes the supercooling of condensed water, and condensate super-cooling not only reduces the condensation efficiency of cooling water,
Lead to chilled(cooling) water supply (CWS) increased costs, and the oxygen content amount in condensed water can be improved, so that the vacuum degree in condenser is influenced, and
Cause the oxidation corrosion of cooling water pipe etc..
All-welded plate shell type stainless steel condenser is disclosed in the prior art and its applies (CN102425958B), is related to
Condenser constitute circulating cooling water flow passage, steam and circulation using the stainless steel plate that fluted and tongue is arranged in surface
Cooling water is condensed into water, is flowed downward with pearl after two side runner of plate carries out heat exchange from top to bottom, converges to poly- steam chest
With the water of polywater room, flowed out through hot well condensation-water drain；
But the chamber of stainless steel plate composition is used to be used for the channel of cooling water, the dosage of cooling water is considerably increased,
Energy consumption is improved, and it cannot eliminate supercooling phenomenon.
