Description
Technical field
The utility model relates to the technical fields of plant condenser pumped vacuum systems, especially a kind of to use height back pressure two
The vacuum of the large thermal power plant condenser of a condenser maintains system.
Background technique
In thermal power plant, condenser vacuum is affected to coal consumption for power generation.The common vaccum-pumping equipment of power plant at present
It is water-jet pump and water ring pump, the former is gradually substituted by the latter.In recent years, occur in the market some with " big with small generation " section
Energy vacuum pump set is for relay or substitutes large-scale liquid rotary pump, realizes the purpose of energy-saving and emission-reduction.For Generator Set, condensing
Device system is often by two condensers of high back pressure and low back pressure.Therefore when using energy saving unit, two energy conservations need to be used
Vacuum pump set is respectively the condenser offer vacuum power of high back pressure and low back pressure, extracts their intermediate incoagulability gas respectively
Body guarantees the vacuum degree of two condensers respectively.
Utility model content
It is applied to thermal power plant's condenser the purpose of this utility model is to provide one kind and vacuumizes energy-efficient integral vacuum
Pumping system can be used set of system when facing double pressure condenser by using evacuation system for steam condenser while tie up
Hold height back pressure condenser, therefore energy conservation more further than existing condenser vacuum energy conserving system, diminution occupied area, reduction
Cost of investment and convenient for control
To achieve the goals above, the technical solution of the utility model are as follows: one kind is applied to thermal power plant's condenser and vacuumizes
Energy-efficient integral vacuum pumping system, when large-size thermal power plant uses two condensers of height back pressure, two condensers point
Not Wei high-pressure side gas trap and low-pressure side gas trap, the system only with a set of single vacuum system simultaneously maintain height carry on the back
Press the vacuum degree of two condensers, vacuum system by vacuum pipe respectively with high-pressure side condenser piping and low-pressure side condensing
The connection of device pipeline, and then it is connected to high-pressure side gas trap and low-pressure side gas trap, first is provided at the condenser piping of high-pressure side
Valve presses and is equipped with the second valve at the condenser piping of side, by being equipped with third valve at vacuum pipe.
It is applied to thermal power plant's condenser the utility model discloses one kind and vacuumizes energy-efficient integral vacuum pumping system, skill
Art effect: only needing a set of pumped vacuum systems that can realize in double pressure condenser while maintaining height back pressure condenser true
Empty effect, thus realize can it is further energy saving on the basis of guaranteeing safety, reduce occupied area, reduce cost and just
In the purpose of control.
Detailed description of the invention
Fig. 1 is Tthe utility model system schematic diagram.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
It is applied to thermal power plant's condenser the utility model discloses one kind and vacuumizes energy-efficient integral vacuum pumping system,
Be different from the prior art and be: when large-size thermal power plant is using two condensers of height back pressure, two condensers are respectively
High-pressure side gas trap 3 and low-pressure side gas trap 8, the system maintain height to carry on the back simultaneously only with a set of single vacuum system 1
The vacuum degree of two condensers is pressed, vacuum system 1 is solidifying with high-pressure side condenser piping 5 and low-pressure side respectively by vacuum pipe 9
Vapour device pipeline 6 connects, and then is connected to high-pressure side gas trap 3 and low-pressure side gas trap 8, at high-pressure side condenser piping 5 at least
Be provided with first valve 4, press at side condenser piping 6 at least provided with second valve 7, by vacuum pipe 9 extremely
It is equipped with a third valve 2 less.
In the specific implementation, the vacuum system 1 is to obtain and maintain the equipment or vacuum system of vacuum for condenser.
Vacuum pump system of the vacuum system 1 including but not limited to roots-type energy conservation unit, water ring pump or other forms.
In the specific implementation, the valve is the common Pneumatic butterfly valve of power plant, or the valve of other forms.
In the specific implementation, the entrance of the evacuation system for steam condenser vacuumizes main pipe by each valve and pipeline simultaneously
It is connected to high-pressure power plant condenser and low pressure condenser, and then with individual integrated vacuum pump can be simultaneously high back pressure and low
Two condensers of back pressure provide vacuum power.But still does not change all-in-one machine monomer and may be implemented than being distinguished with two energy-saving machine groups
It maintains the more energy saving mode of the vacuum degree of high and low back pressure condenser, saving land occupation, reduce cost of investment and control of being more convenient for
Feature.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the utility model specific implementation is confined to these above-mentioned explanations.For the common skill of the utility model technical field
For art personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, all should
It is considered as belonging to the protection scope of the utility model.
