Art field.
Background technique
Power industry is one of major fields of energy-saving and emission-reduction, faces environmental pressure, requirement day of the country to energy-saving and emission-reduction
It is beneficial stringent.Electricity power enterprise must just take and effectively arrange to keep good advantages for development in increasingly fierce market competition
It applies, the net coal consumption rate that unit is greatly lowered is horizontal.
Still there is the condenser of a large amount of units using single back pressure, Double-casing, double fluid in current 600MW grades of country Subcritical Units
Journey, surface cooled condenser.With the increase of domestic steam turbine single-machine capacity and increasing for steam drain, more shells, multiple pressure are solidifying
Vapour device is more and more widely used.Since the average back pressure of double pressure condenser under equal conditions is than single back pressure condenser
It is low, the unit for being equipped with single back pressure condenser is caused, economy is not so good as the unit equipped with double pressure condenser.However by
It selected single back pressure condenser in the design phase in these 600MW grades of subcritical old unit, wanted that being changed as double back pressures coagulates
Vapour device has very big difficulty.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide one kind in prior art basis
It is improving, can reduce thermal power plant gross coal consumption rate, improve generating efficiency, increase economy of power plant benefit, reduce simultaneously
The method of double back pressures transformation of the thermal power plant list back pressure condenser of pollutant emission.
The purpose of this utility model is completed by following technical solution: a kind of double back pressure condensings in thermal power plant
Device system, it include two according to steam turbine generator center line arrangement, be respectively high-pressure side condenser and low-pressure side condenser, institute
There is one section of connecting pipe shut between the high-pressure side condenser stated and low-pressure side condenser throat；The low-pressure side condenser water
It is connected to two circulating water inlets for being respectively provided with secondary filter on the interface of room, and the phase on the condenser water box interface of high-pressure side
It is connected to two circulating water outlet pipes for being respectively provided with ball screen.
As preferred: the high-pressure side condenser is connected with the return water chamber of low-pressure side condenser by cross over pipe,
Two circulating water inlets are connected to an external circulating water inlet road, and two circulating water outlet pipes are simultaneously
It is connected to an external circulating water outlet pipe road.
The utility model, which has the following technical effect that, provides the effective thermal power plant list back pressure condenser of complete set
The method for carrying out double back pressure transformations, improved Contrast on effect are as shown in the table:
As can be seen from the above table, unit generation rated coal consumption will reduce about 0.3g/kWh after the completion of transformation, by 600MW unit
Rated generation amount, calculates 900 yuan/ton of mark coal price for annual utilization hours 5000 hours, can save 900 tons coal-fired, year reduction year
About 810,000 yuan of fuel cost, there is biggish benefit to improving economy of power plant benefit, reducing pollutant emission.
The utility model belongs to the technological transformation to the prior art, and thermal power plant gross coal consumption rate can be reduced by having, and mentions
High generation efficiency increases economy of power plant benefit, while the features such as reduce pollutant emission.
Detailed description of the invention
Fig. 1 is the improved scheme schematic diagram of the double back pressures of condenser in main building described in the utility model.
Fig. 2 is that A described in the utility model arranges outer modification scheme figure.
Fig. 3 is the outer interim schematic diagram for removing enclosed busbar bracket range of A column described in the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing: Fig. 1, shown in 2, a kind of fire described in the utility model
The double pressure condenser system in power power plant, it include two according to steam turbine generator center line arrangement, to be respectively high-pressure side solidifying
Vapour device and low-pressure side condenser, it is characterised in that have one section of envelope between the high-pressure side condenser and low-pressure side condenser throat
Dead connecting pipe 5；Be connected on the low-pressure side condenser water box interface recirculated water that two are respectively provided with secondary filter 3 into
Water pipe 2, and two circulating water outlet pipes 1 for being respectively provided with ball screen 4 are connected on the condenser water box interface of high-pressure side.
As shown in the figure, the high-pressure side condenser is connected with the return water chamber of low-pressure side condenser by cross over pipe 6,
Two circulating water inlets 2 are connected to an external circulating water inlet road, and two circulating water outlet pipes 1
It is connected to an external circulating water outlet pipe road.
Embodiment:
The utility model further embodiment can also include following specific scheme: shown in Fig. 1, by condenser high-pressure
Side original circulating water inlet 1 is exchanged with low-pressure side original circulating water outlet pipe 2, respectively becomes circulating water outlet pipe as shown in the figure
1 and circulating water inlet 2, secondary filter 3 and ball screen 4 are exchanged together with pipeline on pipeline, and condenser water box interface accordingly changes
It makes, finally, condenser high-pressure side connects two circulating water outlet pipe roads, and low-pressure side connects two circulating water inlet roads；
Condenser throat remodeling method: including that will coagulate under the premise of heat exchanger tube is protected to equipment in condenser throat
Connecting pipe 5 between Qi Qi throat is shut；
Condenser ontology pipeline remodeling method: it is connected to as shown in Figure 1, condenser returns to water chamber cross over pipe 6.
The transformation of A column outer circulation waterpipe corresponds to remodeling method according to coagulator interface variation: as shown in Fig. 2, by dotted line institute
The former circulating water pipeline 1 shown is transformed into heavy line and is expressed as circulating water pipeline 2 after transformation；
The utility model is that site operation is transformed in cooperation circulating water pipe, is also required to remove together, again to enclosed busbar is closed on
Dress, position remains unchanged after refitting.As Fig. 3 medium cloud line part 1 illustrates interim dismounting range.
By the implementation of the above remodeling method, economy of power plant benefit can be significantly improved, reduce pollutant emission, have compared with
High promotional value.Increase condenser heating surface area in addition, this remodeling method may also be combined with, increase water circulating pump power output, vapour
Turbine Tong Liao area etc. carries out together, will can reach bigger economic benefit.
The utility model can significantly reduce thermal power plant gross coal consumption rate, improve generating efficiency, increase economy of power plant effect
Benefit, while reducing pollutant emission.
