Brief description of the drawings
Fig. 1 is the heat supply one-level web portal personal system distribution map of pressure electricity-generating more than needed.
Fig. 2 is heat supply, the power supply graph of a relation between one-level net and two grades of nets.
Specific embodiment
The personal system of heat supply one-level web portal pressure electricity-generating more than needed, is transported in the one-level net of heating plant or heat supply initial station
Several heat exchange stations 9, as shown in figure 1, in heating network, supply source exit one-level net ductwork pressure must sufficiently large, ability
Pipe network is overcome to lose on the way, it is ensured that the regular supply of pipe network end N heat exchange stations least favorable point, so near thermal source outlet
Very big pressure is often born in the heat exchange station porch at place, and TRT 1 is set in the heat exchange station porch for having pressure more than needed；Generate electricity
Device 1 is made up of the pipeline coaxially connected synchronous generator of water wheels prime mover, and pipeline pressure more than needed and flow act on pipeline water
Wheel prime mover, to greatest extent using pressure △ P more than needed, so as to convert kinetic energy into electric energy.As shown in Fig. 2 TRT 1 is exported
Electric power is connected by power line with two grades of net circulating pumps 7, and the electric energy that will be converted provides power supply for the circulating pump of two grades of nets.To protect
The uninterrupted operation of one-level heating network is demonstrate,proved, valve 5 is respectively arranged at two ends with TRT 1, two outer ends of valve 5 simultaneously
Connection hand-operated valve 4, even if TRT 1 is in the state of maintenance, valve 5 is closed, and hand-operated valve 4 is in opening, i.e.,
Uninterruptedly heat supply TRT 1 can be repaired, safeguarded simultaneously.
The porch of described TRT 1 sets electric control valve 2, and frequency meter 3 is set in the output end of TRT 1,
The output signal of frequency meter 3 is connected with the input control signal of electric control valve 2.When heat supply network normally runs, pressure △ P more than needed are
Substantially stablize constant, when △ P occur minor fluctuations, surge pressure δ P are born by the electric control valve 2 connected, make generating
Quality control is 50hz ± 5% in output frequency, and voltage output is in the range of three-phase alternating current 400V ± 5%.
Two grades of described power inputs of net circulating pump 7 are connected with the output end of automatic power-supply switch 8, and power supply is certainly
The input of dynamic switching device 8 connects the power supply output line of TRT 1 and the power line of municipal administration electricity respectively.If by thermal source or
Outer net fault impact, pressure △ P excursions of having more than needed are larger, it is impossible to meet power generating quality requirement, automatic transfer switching equipment 8 is certainly
Dynamic switching is powered to municipal power supply, and valve 5 is closed, and hand-operated valve 4 is in opening, and heat supply main pipeline continues to transport
OK.
Described TRT two ends, and on one-level host's pipeline, pressure gauge 6 is respectively equipped with, generating dress can be measured
Put input pressure P1 and output pressure P2.
A kind of personal system of use heat supply one-level web portal pressure electricity-generating more than needed carries out the control method of heat supply network work, including
Following steps：
1）Monitor the pressure P1 of the porch of each heat exchange station 9 respectively by pressure gauge 6, set heat exchange station entrance be actually needed pressure as
P2, then have more than needed pressure △ P=P1-P2；
2）When pressure △ P more than needed meet the power generating quality requirement of TRT 1, then manually-operated gate 4 is closed, start TRT 1
Generate electricity；When wherein TRT 1 selects pipeline water wheels prime mover, the mechanical performance such as its lift flow will have more than needed with live actual
△ P values match；
3）The electricity that TRT 1 sends is monitored by frequency meter 3, when fluctuating smaller, is adjusted by electric control valve 2
Section, will meet the power input of power generating quality requirement to being used in two grades of net circulating pumps 7；
4）When the generated energy of TRT 1 can not meet power generating quality requirement, two grades of net circulating pumps 7 are automatically switched by power supply and filled
Put 8 and be switched to municipal electricity and be powered.
By taking a medium-sized city central heating network as an example, with an initial station, as a example by 100 two grades of net heat exchange stations, entirely
Year heat supply 152 days（3648 hours）Calculate economic benefit estimation as follows：If municipal heating systems there are 100 heat exchange stations, 50% is there are about left
Right heat exchange station can be utilized.Every average generation electric energy about 180,000 KWh per Heating Period of heat exchange station.Annual amount of saving coal is about
22.122 tons, then 50 heat exchange stations, the KWh of Heating Period generated energy 9,000,000, about 1106 tons of annual amount of saving coal.Using pressure more than needed
Power resource reutilization, decapacitation is brought outside great economic benefit to enterprise, also brings suitable environmental benefit and social benefit.
