Technical Field

The invention relates to the field of energy heating systems, in particular to a comprehensive energy heating system.

Background

The central heating of northern areas in China by using different energy sources is an important problem which is concerned at present. For example: the current rural heat supply scheme is as follows: natural gas self-heating or biological energy cogeneration centralized heating or 'coal to electricity' heating, wherein the 'coal to electricity' heating usually changes electric heating equipment into a carbon crystal plate or an air source heat pump.

If the natural gas is independently used for self-heating, the carbon emission is high, the use cost of residents is high, and the natural gas supply failure accident is easy to occur, so that the low-carbon heating demand cannot be met.

If the biomass heat and power combined central heating is independently utilized, the biomass fermentation period is long, the biogas output is limited, and the long-term high-load heating is difficult to maintain, so that the biomass heat and power combined central heating cannot be independently used for rural areas.

If the carbon crystal plate is independently used for heating, the requirement on a distribution network in a heating area is high, and the capacity of a distribution transformer, a low-voltage line main line, a lower household line and a service line in the area need to be improved, obviously, the investment of infrastructure is high, the use cost of a user is also high, and therefore the requirement on low-cost heating cannot be met.

If the air source heat pump is used for central heating alone, the environmental impact is great, for example: in the environment with lower temperature in winter, especially when the demand for heat supply is higher at night, the heat absorbed by the air source heat pump from the air is limited, so that the heating efficiency is reduced rapidly, the heating capacity is limited, and the overheat protection of the compressor is easily triggered, thereby causing the abnormal operation.

Therefore, the above related technologies are used for centralized heating or self-heating, and the requirements of urban and rural heating with low cost, low carbon emission, high energy efficiency and strong stability cannot be met due to the influence of the use cost of residents, the stability of heating, the transformation of urban and rural distribution networks or carbon emission.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Currently, there are more and more means for heating and warming by focusing on winter, for example: in North China, coal-to-gas and coal-to-electricity are mainly adopted to replace fire coal and clean heating, but because a large amount of carbon is discharged in both the coal-to-gas and the coal-to-electricity, the low-carbon heating requirement cannot be met. And then the carbon crystal plate is singly used for electric heating or the biological energy is singly used for heat and electricity combined central heating or the air source heat pump is singly used for central heating or the coal is singly used for electric heating. Due to the influence of the use cost of residents, the use environment, the current weather or the transformation of urban and rural distribution networks, the low-cost and high-efficiency heat supply requirement cannot be met.

In view of this, a set of energy heating schemes with economy, cleanness, safety, stability and high efficiency is needed. Therefore, an embodiment of the present invention provides an integrated energy heating system, as shown in fig. 1, including: photovoltaic power generation device 11, biomass cogeneration device 12, heat and power utilization device 13, wherein, heat and power utilization device 13 respectively includes: a multi-source heat pump 131, a heat storage facility 132, and a heat supply facility 133.

The photovoltaic power generation device 11 is used for generating photovoltaic power in the sunshine mode and outputting the photovoltaic power in the sunshine mode. The photovoltaic power generation device 11 here may be a solar panel, which is one of clean renewable energy sources. The photovoltaic power generation apparatus 11 can absorb photovoltaic solar energy and convert the photovoltaic solar energy into photovoltaic electric energy when sunlight is sufficient. The photovoltaic power generation device 11 in this embodiment is mainly used to output photovoltaic power to the outside in the daytime mode. For example: the photovoltaic power generation apparatus 11 can provide photovoltaic power to the multi-source heat pump 131 during daytime.

The biomass energy cogeneration device 12 is configured to generate auxiliary electric energy by burning biomass energy and convert the waste heat generated by generating the biomass energy into auxiliary heat energy, and output the auxiliary electric energy and the auxiliary heat energy in a sunshine mode, a night mode, a cloudy mode or a rainy mode.

Biomass refers to all living and growing organic matter and its related substances, including plants, microorganisms, animals and their excretions, and waste generated during human activities. Biomass is an energy carrier, which itself has some energy. The part of biomass that can be utilized by people is called biomass resource, and is one of the most main clean renewable energy sources for human beings. For example: the biomass energy can be generated by locally using biogas as biomass in rural areas and can be converted into auxiliary electric energy. Alternatively, the auxiliary thermal energy is generated by biomass energy thermal conversion.

The biomass-energy cogeneration device 12 in the present embodiment is mainly used to supply auxiliary electric energy in the night mode or the cloudy mode or the rainy mode or to supply auxiliary thermal energy in the low-temperature mode by the auxiliary electric energy converted by electricity and the auxiliary thermal energy converted by heat. By using the biomass cogeneration device 12 and the photovoltaic power generation device 11 in cooperation, the photovoltaic power generation device 11 cannot provide photovoltaic power under a non-sunlight environment, and the multi-source heat pump 131 can be supplied with power in time.

It is considered that the auxiliary heat energy provides a heat source instead of the air heat energy in the low temperature mode to stably produce high-grade heat energy with high heating energy efficiency.

The heat storage device 132 is connected to the multi-source heat pump 131, and is configured to store residual heat energy provided by the multi-source heat pump 131 after the necessary heat energy maintains the normal operation of the heat storage device 132, and release the residual heat energy to supply heat to the user in the night mode.

The comprehensive energy heat supply system in the embodiment of the invention comprehensively utilizes the photovoltaic power generation device 11, the biomass cogeneration device 12, the multi-source heat pump 131 and the heat storage equipment 132, and can supply power to the outside in a daytime mode, a nighttime mode, a cloudy mode or a rainy mode or supply heat to the outside in a low-temperature mode. Moreover, the photovoltaic solar energy and the biomass energy belong to clean energy, the carbon emission phenomenon cannot be caused, the use cost of residents is low, and the urban and rural distribution network does not need to be transformed on a large scale. Therefore, the energy-saving device can be applied to external power supply or heat supply in various different modes, and finally can ensure higher energy utilization efficiency.

The multi-source heat pump 131 can also obtain heat energy through the biomass cogeneration unit 12.

The heat storage device 132 is connected to the multi-source heat pump 131, and is configured to store residual heat energy provided by the multi-source heat pump 131 after the necessary heat energy maintains the normal operation of the heat storage device 132, and release the residual heat energy to supply heat to the user in the night mode. The heat storage device 132 is used for storing residual heat energy generated after the multi-source heat pump 131 provides necessary heat energy to maintain the normal operation of the heat storage device, and supplying heat to users in a night mode so as to avoid energy waste.

And the heat supply device 133 is respectively connected with the heat storage device 132 and the multi-source heat pump 131 and is used for acquiring auxiliary heat energy and multi-source heat pump 131 heat energy.

The heat supply facility 133 can still obtain the auxiliary heat energy from the heat conversion of the biomass cogeneration device 12 and the heat energy of the multi-source heat pump 131 output by the multi-source heat pump 131 even in the extremely cold low-temperature mode.

The photovoltaic power generation device 11 and the biomass cogeneration device provide electric power flow for the power distribution station 134, and the power distribution station 134 and the photovoltaic power generation device 11 provide electric power flow for the power supply equipment.

Because rural areas in the north belong to distribution network weak areas, photovoltaic electric energy generated by the photovoltaic power generation device 11 is distributed to a distribution station in the area and then provided to the power supply equipment 135, the daily life of rural residents is facilitated, the weak distribution network is not required to be modified, the purpose of reducing the energy efficiency is achieved, and the economy is achieved.

The comprehensive energy heat supply system in the embodiment of the invention can realize the operation of the urban and rural distribution network in extremely cold weather (in a low-temperature mode), has lower requirements on the structure of the distribution network, and can reduce the power supply burden of the distribution network on the urban and rural distribution network in remote rural weak areas. In addition, the embodiment of the invention comprehensively utilizes the photovoltaic power generation device, the biomass energy cogeneration device and the heat and power utilization device, can realize mutual supplement of energy, ensures stable operation in various different modes, and can improve the utilization efficiency of the energy.
