New energy digestion capability.
Pollution with the aggravation and traditional energy of energy crisis to environment promotes demand of the people to new energy increasingly
It is urgent.The especially transformation of district heating system, in order to energy saving, accumulation of heat water pot is a kind of energy saving mode, will be hot
Heat source is conveyed by heat supply to heat user by district heat supply network after the savings of source.Therefore, fire is promoted by flexibility
Electric system peak modulation capacity, adaptation to local conditions is to solve the effective measures of power surplus using wind-powered electricity generation regenerative resource.
Invention content
The purpose of the present invention is to provide a kind of accumulation of energy, output heating hot water, thermal power plant that is energy saving, automatically controlling are deep
Spend peak regulation flexibility hold over system.
In order to achieve the above object, thermal power plant's depth peak regulation flexibility hold over system of the present invention, when being included in peak load regulation network
Between section connect high-voltage switch gear high-tension switch cabinet, connect with high-tension switch cabinet and by its instruction control accumulation of heat water pot, with accumulation of heat
The heat exchanger that water pot is connected directly by waterway pipe, the heating hot water pipeline connected on heat exchangers, heating water return pipeline,
The heat exchange blower fan connected between accumulation of heat water pot and heat exchanger, the variable-frequency governor for connecting and being controlled by it with heat exchange blower fan, with change
The low-voltage power distributing cabinet of frequency governor connection, the PLC controller being connected with high-tension switch cabinet, low-voltage power distributing cabinet, in accumulation of heat water
Several accumulation of heat water tank temperature sensors that temperature measuring point is arranged and is connected with PLC controller inside tank, the thermometric inside heat exchanger
Several heat exchange temperature sensors that point is arranged and is connected with PLC controller.
Thermal power plant's depth peak regulation flexibility hold over system of the present invention, operation principle are：In the peak load regulation network period, foundation
PLC controller instructs high-tension switch cabinet to connect high-voltage switch gear, and high-voltage fence is powered for accumulation of heat water pot, and accumulation of heat water pot converts electrical energy into
It is constantly absorbed by accumulation of heat water pot simultaneously for thermal energy；At the end of the peak regulation period, PLC controller instructs high-tension switch cabinet cutoff high
Switch, high-tension switch cabinet high-voltage fence stop power supply, realize PLC controller and automatically control.Accumulation of heat water pot is stopped, accumulation of heat
Between water pot and heat exchanger using hot-air crosslinking output, heat exchanger by the high temperature heat that accumulation of heat water pot stores be converted to hot water or
Person's steam exports.
Thermal power plant's depth peak regulation flexibility hold over system of the present invention, the essence of the accumulation of heat water pot course of work are exactly accumulation of heat, put
The process of heat.When user's thermal load demands are relatively low, the waste heat that electricity generation system generates is absorbed and is stored by accumulation of heat water pot, etc.
Heat is released when being risen with thermic load, it is energy saving in this way.When accumulation of heat water pot works, ensure its water-in and water-out flow equilibrium, and
Transition zone is kept to stablize when hot water or cold water's liquid level changes up and down.In addition, to avoid water dissolution oxygen in accumulation of heat water pot and by these water
It brings heat supply network into, influences heat supply network circulating water quality, steam or nitrogen are usually poured on the liquid level in accumulation of heat water pot, keep micro-positive pressure,
Make the water in accumulation of heat water pot and air insulated.
Thermal power plant's depth peak regulation flexibility hold over system of the present invention, accumulation of heat water pot inside can store hot water and cold water simultaneously.
Water temperature is different, and the density of water is also different, and in a sufficiently large container, due to gravity, the different hot and cold water of density is certainly
So layering, hot water is upper, and for cold water under, centre forms transition zone.When heat source quantity of heat production is more than user's heat amount, accumulation of heat water pot
Accumulation of heat, when accumulation of heat, hot water enters from top water pot, and cold water is discharged from lower part water pipe, and transition zone moves down；When heat source quantity of heat production
When less than user's heat amount, accumulation of heat water pot heat release, when heat release, hot water is discharged from top water pipe, and cold water enters from lower part water pipe, mistake
Layer is crossed to move up.The quality of water is to maintain invariable in tank body, and energy is variation.
Thermal power plant's depth peak regulation flexibility hold over system of the present invention, in the society's electricity consumption amount ebb period at night, station boiler
Unit participates in carrying out depth peak regulation, while the hot water in accumulation of heat water pot is fed directly to heat supply in heat supply network water main pipe, to keep away
Exempt from the problem of heating steam extraction deficiency during peak regulation.
Thermal power plant's depth peak regulation flexibility hold over system of the present invention, accumulation of heat water pot are worked using the self-heating principle of stratification, are utilized
Water different characteristic of density in different temperatures makes the water conservancy of different temperatures be layered with density contrast, to keep away by water distribution system
Amount of stored heat loss or heat storage efficiency reduce caused by exempting from hot water or cold water mixing, are finally reached heat accumulation purpose.Water distribution system is set
Meter is sought to by accurately calculating and arranging, is entered or is drawn accumulation of heat water pot to control water flow stationary, reduce water as far as possible
Disturbance reduces thermoclinic thickness, improves heat accumulation dischargeable capacity.
Thermal power plant's depth peak regulation flexibility hold over system of the present invention, heat-accumulating process are：Hot water is from accumulation of heat water pot top hot junction
Water pipe enters in tank, hot water is distributed in top aqueous layer by upper water distributor inside accumulation of heat water pot, while being pressed down against cold water, led to
Lower water-dispensing device inside accumulation of heat water pot is crossed to flow out outside tank from lower part cold end water pipe.Exothermic process is：Cold water from lower part cold end water pipe into
Enter in accumulation of heat water pot, cold water is distributed in by lower water layer, while upward hot water by lower water-dispensing device inside accumulation of heat water pot, is led to
Upper water distributor inside accumulation of heat water pot is crossed to flow out outside accumulation of heat water pot from top hot junction water pipe.
In conclusion thermal power plant's depth peak regulation flexibility hold over system of the present invention, accumulation of energy, output heating hot water save energy
Source automatically controls.
