Abstract
A heat supply method and device comprehensively utilizing steam energy of a thermal power plant solve the problem that partial steam energy of the thermal power plant is not fully utilized because partial steam is directly sent to a user for heating without being generated by a steam turbine. The method is characterized in that the generating capacity is determined according to the heat supply quantity, so that the steam generated by a boiler is used for driving a steam turbine to generate power and then is sent into a heating system, meanwhile, the redundant electric quantity generated by a thermal power plant is sent to a remote area through a single internal power grid, and is converted into heat energy through a heat pump arranged in the area to supply heat for users. The method can send the surplus electric quantity of the thermal power plant to a remote place through an internal power grid, and heat is generated by a heat pump for heating. Improves the comprehensive utilization rate of the steam and reduces the environmental pollution.
Description
The invention belongs to electric heating coproduction dwelling house central heating system, particularly heat pump heating device.
Existing steam power plant promptly generates electricity when heating again in the winter time, sends into house heating behind the steam drive steam turbine.But owing to limited by power consumption, electrical network allows steam power plant's generating and sends into the electric weight of electrical network limited.Produce the needs that the required steam of electric energy in a small amount like this far can not satisfy heat supply, therefore, steam power plant will produce steam direct heating with boiler, reduce the benefit of generating.Steam heating must be laid pipeline, and needing for remote heat supply increases length of pipeline and diameter, sets up pumping plant, and therefore, equipment investment is bigger, and thermal losses is big, and practical operation is not easy to realize.
The purpose of this invention is to provide a kind of heat supply method and system, it can solve steam power plant and be subjected to the electrical network restriction contradiction that generated energy is little, heating load is big and the problem of remote heat supply.
To achieve these goals, following technical scheme is proposed.
A kind of method that fully utilizes steam energy of steam-power plant, it is characterized in that according to heating load decision generated energy, the steam that boiler is produced all is used for the driving steam turbine generating, and then send into heating system, the unnecessary electric weight that steam power plant is produced is delivered to area far away by independent internal electric network simultaneously, produces heat by the heat pump that is installed in this area and sends into user's heating.
For implementing said method, design following heating system.
A kind of heating system that fully utilizes steam energy of steam-power plant is characterized in that it comprises steam turbine, generator, the internal electric network of steam power plant and is installed in the heat pump heat supply station of residential quarters, and the heating network that links with heat pump, radiator.
In order to regulate the contradiction between heating load and the steam power plant's generated energy, between heat pump and heating user radiator, regenerative apparatus is installed.Like this, when the heat that heat pump produces temporarily can being stored in the regenerative apparatus with heat hour
Above-mentioned " heat pump " both comprised air-conditioning class device, also comprised the refrigeration kind equipment, as Chinese patent ZL94216590, the X multifunctional heating wetting system of my application.
The present invention has following advantage:
1, the steam that can make steam power plant is all to steam turbine acting, generating, and the afterheat steam of finishing after the merit is sent into user's heating, and like this, steam has double benefit.
2, can build steam power plant less, reduce capital construction, equipment investment, reduce environmental pollution.The heat pump heat supply factory of the function that heats separately, the comparable steam power plant that builds reduces by 50% investment, reduces by 50% environmental pollution, improves former steam power plant power benefit 50%.
3, because the Energy Efficiency Ratio of heat pump is 1: 4-5, promptly 1 kilowatt of eletctric energy (KWE) produces 4-5 kilowatt of heat.
4, the electric energy of steam power plant's generation is fit to remote the conveying, strides across river and mountain valley easily, for the residence area away from steam power plant is sent to electric energy, converts the heat energy heating to by heat pump again.
Description of drawings:
Fig. 1 is the schematic diagram of system of the present invention, and Fig. 2 is a former steam power plant heat energy utilization schematic diagram.
Embodiment:
With the Jinzhou City is example, and existing two steam power plants are essentially the town house heating.Owing to limited by the electrical network power consumption, these two steam power plants are when power consumption is minimum in the winter time, send into residential heating after having only 30% steam-electric power, and 70% steam are directly used in heating.Such 70% steam is not fully used.On the other hand, still there are large areas in this city, and as the economic development zone, the hi-tech park does not have the central heating facility.If build steam power plant again, both increased investment, again contaminated environment.Adopt the technical program, the steam that is used for heat supply all can be generated electricity by steam turbine.And the internal electric network that the electric weight that surpasses the electrical network demand that generator produces is built by other is sent into the newly developed area that needs heating, and heat pump is installed in the residential area, the electric energy that utilizes steam power plant to send here drives operation of heat pump, converts electric energy to heat energy by heat pump again and sends into user's heating.
The system that realizes such scheme comprises steam turbine, generator, the internal electric network of building in addition of steam power plant and is installed in economic development zone, the hi-tech park with the internal electric network is the heat pump assembly of power supply, and the heating network that links with heat pump, the radiator that the user is indoor etc.In order will temporarily to store, between heat pump and user's radiator, regenerative apparatus is installed with the heat that heat hour heat pump produces.
During this system works, the steam that thermal power plant boiler produces drives generator for electricity generation all by steam turbine.The steam that comes out from steam turbine in work done generating back is sent into user's heating of the former heating area of steam power plant.The generating amount that the electric energy part that generator produces is assigned by utility network is sent into utility network, and the internal electric network that unnecessary electric weight is built by other is sent into economic development zone, high and new tech park, for the heat pump running that is installed in the there.The hot water that heat pump produces is sent into local user's heating by pipe network.
Adopt this technical scheme, the steam of steam power plant is all generated electricity earlier afterwards send into user heating, make full use of its heat energy.Like this, in economic development zone and hi-tech park, just need not build steam power plant, reduce capital construction, equipment investment, reduce environmental pollution.Utilizing the electric energy that has steam power plant to convert heat energy to by the heat pump in economic development zone and hi-tech park is the user of this area heating.This mode is economy but also convenient not only.
