Description
Technical field
The utility model relates to steam turbine and auxiliary cooling device correlative technology field, specifically, and a kind of Novel steam condenser.
Background technology
The most of Power Plant of current China runs low vacuum, and condensate undercooling is comparatively large, and what cause unit effectively utilizes enthalpy drop low, and heat loss strengthens, uneconomical.
Unit output decreases simultaneously; Exhaust temperature raises, and condenser copper tube may be made to relax, destroy tightness; Exhaust temperature raises, and makes exhaust casing and bearing block expanded by heating, causes center to change, and produces vibration.
Steam turbine axial displacement increases, and causes thrust bearing transship and wear and tear; Vacuum declines and the volume flow of steam discharge is reduced, and produce larger exciting force to a certain position of exhaust stage blade, likely damaged blade, causes the accident.
Therefore, how existing condenser is improved, solves the problems referred to above, be those skilled in the art faced by.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of Novel steam condenser.Condenser provided by the utility model, by designing brand-new laryngeal structure, effectively can improve the vacuum of unit, and exerting oneself of unit becomes large, decreases the heat loss of unit, reaches energy-saving and cost-reducing object, ensured the safe operation of unit.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of Novel steam condenser, comprising:
Shell; One end of shell is connected with condenser throat, and the other end of shell is condensate water outlet;
Described enclosure has flow process demarcation strip, and the both sides up and down of flow process demarcation strip are cooling water pipe, and cooling water pipe is communicated with the cooling water flow conduits be positioned on side wall of outer shell;
Described condenser throat is the prismatoid structure of upper and lower opening, and this condenser throat is divided into the first half and the latter half;
The end of the first half is steam inlet, and the end of the latter half is steam (vapor) outlet, and steam (vapor) outlet is connected with shell is airtight.
Preferably, the sidewall of described condenser throat is also connected with air duct, and the other end of air duct is connected with main picking device.
Preferably, described main picking device is aspiration pump.
Preferably, valve is provided with between described main picking device and air duct.
Preferably, the connected node of described air duct and condenser throat is positioned at the latter half of condenser throat.
The beneficial effects of the utility model are:
(1) condenser throat of existing rectangular structure is changed into the condenser throat of prismatoid structure, the latter half of condenser throat is expanded, improves and utilize enthalpy drop, form high vacuum in turbine discharge mouth bottom.Because the throat of steam turbine strengthens, reduce pressure, reduce air velocity, and gas is spread to both sides, is be vented copper pipe contact area in effective and condenser to strengthen, improves cooling effect, increase the usable enthalpy drop of steam in steam turbine, improve circulating vacuum.
(2) incondensable gas affects heat-transfer effect in condenser, causes larger heat loss.Released by incoagulable for condenser throat gas by air duct and main picking device, reduce condenser pressure, slowed down gas flow rate, extends stroke and time that gas turbine exhaust gas stops in condenser.Make the raising of steam turbine vacuum, heat-transfer effect improves thereupon, and heat loss reduces, thus reaches energy-saving and cost-reducing object.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment: a kind of Novel steam condenser, it has shell 6; The upper end of shell 6 is connected with condenser throat 2, and the other end of shell 6 is condensate water outlet 7;
Described shell 6 inside has flow process demarcation strip 10, and the both sides up and down of flow process demarcation strip 10 are cooling water pipe 12, and cooling water pipe 12 is communicated with the cooling water flow conduits 9 on the sidewall being positioned at shell 6; The lower end of cooling water flow conduits 9 is cooling water inlet 8, and upper end is coolant outlet 11.
In above-mentioned Novel steam condenser, described condenser throat 2 is the prismatoid structure of upper and lower opening, and this condenser throat is divided into the first half and the latter half;
The end of the first half is steam inlet 1, and the end of the latter half is steam (vapor) outlet, and steam (vapor) outlet is connected with shell 6 is airtight.
In order to improve energy-saving effect further, the sidewall of described condenser throat 2 is also connected with air duct 3, and the other end of air duct 3 is connected with main picking device 5.
According to different needs, described main picking device 5 can be aspiration pump or other devices.
For the ease of controlling, between described main picking device 5 and air duct 3, be provided with valve 4.
Described air duct 3 and the connected node (can be considered the axis of air duct 3) of condenser throat 2 are positioned at the latter half of condenser throat 2.
To the condenser of certain specification, end extent and condenser cooling water inlet temperature, condenser unit are steam load, condenser copper tube surface cleanliness, the leaking-in air amount in condenser and the flow velocity of cooling water in pipe relevant.A clean condenser, just has certain end difference index under certain circulating water temperature and quantity of circulating water and unit steam load, and general end difference index is that cooling water outlet temperature is lower when quantity of circulating water increases, and end difference is larger, and vice versa; Unit steam load is larger, and end difference is larger, and vice versa.
In the utility model, steam enters from steam inlet 1.Cooling water enters from cooling water inlet 8, becomes cooling water after flowing through cooling water pipe 12, flows out from coolant outlet 11.Steam is when through condenser throat 2, because condenser throat 2 is prismatoid structure, so more downward, flow velocity is slower, is to be vented copper pipe contact area in effective and condenser to strengthen, and improves cooling effect, increase the usable enthalpy drop of steam in steam turbine, improve circulating vacuum.
Especially heating period in the winter time, Be very effective.Condenser retrofit initial vacuum is-0.088MPa, vacuum-0.075MPa during heat supply in winter, after transformation, under the same terms, vacuum becomes-0.095MPa, during heat supply in winter, vacuum-0.088MPa. vacuum often reduces 1KPa, hear rate about increases by 1.05%, and gross coal consumption rate is about 3.0g/kwh, and steam turbine is exerted oneself and reduced about 1%, so, improved effect clearly.
Improved condenser, degree of supercooling reduces, and means that the heat that recirculated water is taken away is few, and unit economy is just better.
After have employed above-mentioned new construction, the degree of supercooling of condenser, also just about once, is provided with better economic benefit.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can when not departing from spirit or scope of the present utility model, realize in other embodiments, the part be not described in detail, for prior art, do not repeat at this.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and feature.
