Description
Technical field
This utility model relates to a kind of deaerating plant, is specifically related to the built-in deaerating plant of a kind of condenser.
Background technology
Along with expansion and the development of electricity market, thermal power plant unit Heating Period at full capacity time need the heating of substantial amounts of heat supply network to steam
Vapour, produces the hydrophobic flow of heat supply network relatively big simultaneously, needs to be directly discharged in condenser.But due to heat supply network hydrophobic in dissolved substantial amounts of
Gas, such as elimination of not adopting an effective measure, is directly discharged in condenser hotwell, it will cause the dissolved gas of condenser condensed water
Amount severe overweight, and then the equipment such as boiler, steam turbine is caused corrosion harmfulness, especially oxygen is the strongest to the corrosivity of equipment.Fall
In the low service life of unit, in order to ensure the safe operation of unit, improve service life of equipment, heat supply network should be removed as far as possible and dredge
Dissolved oxygen in water.So setting up deaerating plant inside condenser hotwell.
Utility model content
This utility model for solve existing thermal power plant unit Heating Period at full capacity time need substantial amounts of heat supply network to add vapours, produce
Heat supply network is hydrophobic to be entered in condenser hotwell, causes the quantity of dissolved gas severe overweight of condenser condensed water, and then to boiler, steamer
The equipment such as machine cause corrosion harmfulness, and especially oxygen is the strongest to the corrosivity of equipment, affects the service life of unit, increases and produce into
This problem, and then the built-in deaerating plant of a kind of condenser is provided.
This utility model adopts the technical scheme that for solving the problems referred to above: it includes hydrophobic mouthpiece, equal tee, master
Pipe, multiple arm and multiple closure plate, the sidewall of each arm is all machined with multiple aperture, hydrophobic mouthpiece and equal tee
First interface connects, and supervisor is arranged on the second interface and the 3rd interface of equal tee, and supervisor is respectively arranged at two ends with closure plate,
And hydrophobic mouthpiece connects with the sidewall of supervisor, multiple arms are uniformly arranged on supervisor, and supervisor and multiple arms are all laid on
Bottom in condenser hotwell, one end of each arm is all connected with the sidewall being responsible for, and the other end of each arm is provided with closure plate.
The beneficial effects of the utility model are:
1, the hydrophobic entrance of heat supply network accesses deaerating plant of the present utility model from condenser hotwell sidewall locations.Deaerating plant is
It is laid in condenser hotwell inner bottom part by a supervisor 2 and multiple arm 3.It is provided with support floor below supervisor 2 and multiple arm 3
4 fix with condenser bottom welding, prevent pipe vibration.And each arm 3 uniformly opens some aperture 3-1, aperture 3-1's is total
Area and the cross-sectional area more than heat supply network hydrophobic water inlet pipe entrance.And it is designed with discharge outlet at main drain 2 and arm 3 end
And closure plate 6.
2, owing to heat supply network drain temperature is higher than saturation temperature under back pressure of condenser, heat supply network during contacting with condensation water
Oxygen in hydrophobic can the most all separate out, and at this moment the vapor partial pressure power on the water surface is close to the total pressure on the water surface, partial pressure
Oxygen and the noncondensing gas of precipitation, close to zero, are expelled directly out condenser through the evacuation trachea being located at air cooling zone, thus reach by power
Effect to deoxygenation.Ensure that the properly functioning of unit, extend the service life of unit, saving production cost, heat supply network is dredged simultaneously
Condensation water in hot well is heated by water, significantly reduces the degree of supercooling condensing water, improves the thermal efficiency of whole unit.
3, deaerating plant is arranged on inside condenser hotwell by this utility model, can save occupation of land space and deaerating effect
Good, simple in construction, safe and reliable, manufacturing process simplifies, with low cost, beneficially popularization and application.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure front view, and Fig. 2 is A-A direction view in Fig. 1, Fig. 3 be in Fig. 1 B-B to regard
Figure, Fig. 4 is C-C direction view in Fig. 1.
Detailed description of the invention
Detailed description of the invention one: combine Fig. 1-Fig. 4 and present embodiment is described, a kind of condenser described in present embodiment
Built-in deaerating plant, it includes hydrophobic mouthpiece 1, equal tee 5, supervisor 2, multiple arm 3 and multiple closure plate 6, each arm 3
Sidewall on be all machined with multiple aperture 3-1, hydrophobic mouthpiece 1 is connected with the first interface of equal tee 5, and supervisor 2 is arranged on
On second interface of equal tee 5 and the 3rd interface, supervisor 2 is respectively arranged at two ends with closure plate 6, and hydrophobic mouthpiece 1 and supervisor 2
Sidewall connection, multiple arms 3 be uniformly arranged on supervisor 2 on, supervisor 2 and multiple arm 3 be all laid in condenser hotwell
Bottom, one end of each arm 3 is all connected with the sidewall being responsible for 2, and the other end of each arm 3 is provided with closure plate 6.
Detailed description of the invention two: combine Fig. 1, Fig. 3 and Fig. 4 and present embodiment is described, a kind of condensing described in present embodiment
The built-in deaerating plant of device, it also includes that multiple support floor 4, the bottom of each arm 3 are provided with multiple support floor 4, and
Arm 3 is fixing with the top supporting floor 4 to be connected, and the bottom of supervisor 2 is provided with multiple support floor 4, and is responsible for 2 and supports floor
The top of 4 is fixing to be connected, and each support floor 4 is fixedly mounted on condenser base plate, other composition and annexation and tool
Body embodiment one is identical.
Detailed description of the invention three: combine Fig. 1-Fig. 2 and present embodiment is described, a kind of condenser described in present embodiment
Built-in deaerating plant, described aperture 3-1 is circular hole, and the span of a diameter of d, d of circular hole is 8mm-12mm, and this practicality is new
In type, on multiple supervisors 2, the summation of aperture 3-1 area is more than the cross-sectional area of heat supply network hydrophobic water inlet pipe entrance, because of drop diameter very
