Description

Combined type environment-friendly thermal power generation and energy storage system

Technical Field

The invention relates to the technical field of electricity generation and energy storage, in particular to a combined type environment-friendly thermal electricity generation and energy storage system for generating high-temperature steam and performing thermal power generation by combusting methanol fuel in a boiler.

Background

As petrochemical energy is becoming shorter and shorter, alternatives are being sought actively by all parties. The green energy power generation is always the first choice in the alternative scheme, however, no matter the solar power generation or the wind power generation, the green energy power generation has the defects of unstable power generation amount and poor power generation benefit.

Gas turbines are conventionally used in power generation systems and methods. Which extracts energy from a flow of combustion gases directed through blades present in the turbine to rotate a turbine shaft. Energy may be taken from the rotating shaft by a generator to provide power in the form of electricity. However, gas turbine assemblies typically need to be formed from high performance materials, and therefore gas turbines are often high cost components of power generation equipment.

The use of high temperature steam is also a common means of generating electricity. It is produced primarily by heating a boiler to generate high temperature steam and directing the high temperature steam to a predetermined power generating set. However, this method can dissipate a lot of heat energy during the conduction process, so the power generation efficiency can not be optimized. In addition, most of the fuel required by the heating boiler is petrochemical fuel or coal, so that the heating boiler has the disadvantages of generating empty pollution besides the consideration of higher cost and reducing quantity.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1, the power generation system according to the embodiment of the present invention includes a boiler device 10, a steam guiding pipe 20, a power generation module 30 and a heat storage pipe 40. Wherein the boiler assembly 10 includes a furnace body 12 and a burner 14 coupled to the furnace body 12. Wherein the burner 14 provides heat energy using a predetermined methanol fuel so that the furnace body 12 can provide high temperature steam. The vapor delivery tube 20 has a first end 22 and a second end 24. The first end 22 of the vapor nozzle 20 is adapted to be connected to the furnace body 12 of the boiler assembly 10.

The power generation module 30 may be a thermoelectric power generator module. The power generation module 30 is connected to the second end 24 of the steam guide pipe 20, so that the high-temperature steam output by the boiler device 10 can enter the power generation module 30 through the steam guide pipe 20 to generate power.

The heat storage tube 40 has a first inlet end 42 and a second inlet end 44. The first inlet end 42 is for connecting the furnace body 12 of the boiler arrangement 10; the second inlet 44 is used to connect the power generation module 30. Thus, part of the high temperature steam output from the boiler 10 and the rest of the high temperature steam generated by the power generation module 30 can flow into the heat storage pipe 40.

As shown in fig. 2 and fig. 3, the heat storage tube 40 provided in this embodiment is a continuous curved structure, and the surface of the heat storage tube 40 has a plurality of attachment surfaces 46, and the attachment surfaces 46 are in a planar configuration, thereby facilitating the installation or coating of a super heat conductive medium 47 (see fig. 3 for details), such as a graphene material, on the surface. The present embodiment further includes a plurality of thermoelectric conversion modules 50. Each of the thermoelectric conversion modules 50 is mounted and positioned on the mounting surface 46 of the surface of the heat storage pipe 40. Thus, each thermoelectric conversion module 50 can perform an electric-thermal conversion by absorbing the heat conducted from the surface of the heat storage tube 40.

As shown in fig. 4, the present embodiment further includes an energy storage device 60 electrically connected to each of the thermoelectric conversion modules 50 and/or the power generation modules 30, so that the energy storage device 60 can be used to store the electric energy generated by each of the thermoelectric conversion modules 40 and/or the power generation modules 30. Further, in order to make the collecting action of the electric energy more reliable and managed, one or more Battery Management Systems (BMS)62 may be disposed and electrically connected between the thermoelectric conversion module 50 and the energy storage device 60; similarly, one or more Battery Management Systems (BMS)62 may be disposed between the power generation module 30 and the energy storage device 60 and electrically connected thereto.

Particularly, the two ends of the heat storage pipe 40 are respectively connected to the furnace body 10 and the power generation module 30, so that heat energy is deliberately retained inside a predetermined pipeline, and the heat storage pipe 40 adopts a continuously curved structure, which not only can increase the retention amount of high-temperature steam in the heat storage pipe 40, but also can reduce the flow rate of high-temperature steam in the pipe, so that the time for each thermoelectric conversion module 50 to absorb high-temperature heat energy can be increased, thereby improving thermoelectric conversion efficiency, achieving space (curved structure) exchange time, and greatly improving power generation efficiency by exchanging time for heat energy. Due to the structural characteristics of the heat storage tubulation 40, the heat convection and heat conduction effects are enhanced, wherein the heat transfer rate can be enhanced by 25-30%, and the power generation efficiency of the thermoelectric conversion module 50 can be enhanced by 20-25%.

Further, a cooling/heating unit 72 has a duct 74, and the duct 74 is connected to the first exhaust duct 70. Thus, part of the high temperature vapor in the first exhaust pipe 70 can be introduced into the cooling/heating unit 72, so that the cooling/heating unit 72 can provide cooling or heating.

As shown in fig. 1 and 5, the present embodiment further includes a second exhaust pipe 80. One end of the second exhaust pipe 80 is connected to the heat storage pipe 40, and the other end is an open port 82 for discharging vapor. It is noted that the second exhaust pipe 80 may have a continuously curved structure, and the surface of the second exhaust pipe 80 has a plurality of mount faces 84 of a planar configuration, and the thermoelectric conversion module 50 can be mounted and positioned so as to be located above the mount faces 84.

The power improver comprises water, potassium nitrate and fusel oil, wherein the mass ratio of the water in the power improver is 30-50%. The ratio of water in the whole can be less than 1%. The secondary water and the methanol can have the effect of power enhancement after mixed reaction.

The modified methanol fuel can also contain ethanol, propanol or butanol within a preset mass ratio; further, the individual mass or the sum of the individual masses of ethanol, propanol or butanol is less than the mass of methanol.

The flash point regulator can increase the evaporation capacity of methanol gasoline, thus increasing the pressure in the container, reducing the flash point, facilitating ignition and feeding for combustion.

One or more of the above-mentioned solubilizing agents for antifreeze, combustion improver, oxygen enhancer, boiling point modifier, calorific value enhancer, detergent, flavoring agent or flash point modifier may be referred to as an additive aid, and the additive aid may be added appropriately according to actual needs.
