Background technology
The 5th assessment report display carbon dioxide ratio of concentration in an atmosphere of Intergovernmental Panel on Climate Change (IPCC) has exceeded 40% before industrialization, coal-burning power plant is as maximum CO2 emission source, and the discharge controlling its carbon dioxide receives much attention.Current major measure is flue gas to carry out carbon trapping and seals (CCS) up for safekeeping, existing carbon trapping technique can be divided into post-combustion capture, pre-combustion capture and oxygen-enriched combusting trapping, wherein widely used is post-combustion capture, namely utilizes the flue gas that burning is generated by the method such as physical absorption or chemical absorbing to carry out CO2Trap, transport and seal up for safekeeping.But, traditional post-combustion capture technology such as MEA process, cold ammonia process etc. can consume substantial amounts of bleeder steam heat energy thus causing the reduction of power plant's net power output and generating efficiency.
On the one hand, gas hydrate refers to the class that some gas molecule (is generally high pressure low temperature) under uniform temperature and pressure and water is formed and includes the ice-like crystal in cage type space.Carbon dioxide can react generation carbon dioxide hydrate under uniform temperature and pressure condition with water, then changes temperature and pressure condition so that it is departing from region of balancing each other, the carbon dioxide in release cage, thus realizing the trapping of carbon dioxide.Hydrate carbon trapping technique can be applied in power-plant flue gas the trapping of carbon dioxide as a kind of emerging capture method, major advantage has that technological process is simple, energy consumption is relatively low, operating condition is gentle, gas reclaiming rate is high, additionally, the power consumption that energy consumption is compressor and water pump etc. of about the 70% of hydrate carbon trapping technique.
On the other hand, solar energy is inexhaustible, nexhaustible regenerative resource, is constantly subjected to the extensive concern of countries in the world.As main clean energy resource, the conversion process of energy of solar energy power generating is simple, stable and reliable operation, and assembly is simple, volume is little, lightweight, it is simple to transport and installing, thus obtaining extensive application.But, constraint due to time and regional condition, it is difficult to round-the-clock utilize solar energy resources, Large Copacity and long-life energy storage device such as lithium battery can be utilized to realize fully storing and stable output of electric power, wherein lithium battery have that environmental protection, safety, specific energy be high, life-span length and the feature such as non-maintaining, be suitable as the energy storage device of photovoltaic generating module.
If, with solar energy power generating, carbon trapping system is carried out energy consumption supply, can farthest utilize natural energy resources, the requirement of power plant's carbon dioxide discharge-reduction can be met again, reduce power plant's energy loss.
Therefore, from the starting point of brand-new reduction energy consumption, develop a kind of system effectively utilizing solar energy and reducing carbon capture in power plant energy consumption, be the desired technical effectively alleviating greenhouse gas emission.
The related invention of solar energy auxiliary hydrate carbon trapping technique mainly has following characteristics:
On the one hand, some inventors carry out integrated angle from hydrate carbon trapping technique and other technologies and study.Such as: hydrate carbon trapping technique and other trapping techniques are carried out integrated by the patent that publication number is CN104028079A, a kind of new collecting carbonic anhydride method is proposed, this technological synthesis ionic liquid and two kinds of collecting carbonic anhydride modes of hydrate, realize the dual trapping to carbon dioxide of ionic liquid aqueous solution and gas hydrate, significantly increase the arresting efficiency to carbon dioxide, there is better industrial application value.Hydrate carbon trapping system and other system are carried out integrated by the patent that publication number is CN103861444A, a kind of collecting carbonic anhydride based on hydrate and desalinization combined production device are proposed, in meeting generating plant flue gas while collecting carbonic anhydride needs, fresh water can also be produced, it is adaptable to the fossil-fuelled power plant of coastal area realizes collecting carbonic anhydride and desalinization coproduction.But, above patent is innovated just for the angle of carbon dioxide hydrate circulation and system, the problem that still can face energy consumption, is difficult to the direction trapping energy consumption reduces and has breakthrough.
On the other hand, some inventors study from the angle of hydrate carbon trapping system optimization.Such as: hydrate carbon capturing device is optimized by the patent that publication number is CN102432008A, it is proposed to a kind of circular carbon dioxide capture device with hydrate method.In this invention, the annular release tower of design can effectively solve the problems such as gas hydrate synthesis speed is slow, temperature-responsive is slow, and avoids the porous media pore plugging caused because of gas hydrate synthesis, it is possible to realize hydrate collecting carbonic anhydride fast, economical.Hydrate carbon trapping system is transformed by the patent that publication number is CN105080323A, it is proposed to a kind of new carbon dioxide capture system based on hydrate, this system makes full use of workshop-sink and realizes the trapping to factory's CO 2 waste gas.Carbon dioxide hydrate crystal is easily separated at normal temperatures and pressures, is possible not only to the carbon dioxide in trapping waste gas, it is also possible to extract pure water from waste liquid.But, above patent is optimized innovation just for the structure of hydrate carbon trapping system, is difficult to accomplish desirably to optimize processing request to the transformation of hydrate system in actual market；Additionally, above patent does not ensure that the seriality of collecting carbonic anhydride, speed of giving vent to anger is slower.
Additionally, also have some inventors to assist the angle of carbon trapping technique to study from solar energy.Such as: application number is that the heat that the patent of US2010/0005966A1 proposes to utilize solar thermal collector to collect directly feeds the reboiler of coal-burning power plant's absorption process (ethanolamine) carbon trapping system, and replacement steam turbine low-temp low-pressure draws gas.Publication number is the system of patent a kind of solar energy assisted coal fired carbon capture in power plant of proposition of CN103372371A, utilize the heat energy that solar thermal collector is collected, first drive organic Rankine bottoming cycle generating, generated energy the supply pump of carbon trapping system, compressor etc., the reboiler energy supply that the heat of condensation is carbon trapping system of recycling condenser.The patent that publication number is CN103752142A proposes the integrated system that a kind of solar energy auxiliary carbon dioxide traps, the height of the energy requirement grade of associated components between solar energy heating subsystem and power generation sub-system and collecting carbonic anhydride subsystem is carried out rational distribution and integrated, it is achieved that the cascade utilization of energy.The patent that publication number is CN104307308A proposes a kind of process system utilizing photovoltaic auxiliary coal unit decarburization, photovoltaic system add heat absorption carbon trapping system and reduce extracted steam from turbine.But, the combination that above patent traps just for Solar use and absorption process carbon, do not relate to other capture method, but the regeneration energy consumption of absorption process carbon trapping itself is higher, if the words that the energy consumption 100% of carbon trapping system is supplied by solar energy, economy of power plant benefit will decline to a great extent, and which limits the development of solar energy assist absorption method carbon trapping technique.
