Problems solved by technology

[0006] 1. Since the driving force of the turbine generator mainly depends on the natural wind power, the turbine generator needs wind field resources with sufficient wind power, and the limited and sufficient wind field resources also limit the large-scale application of wind power generation;
[0007] 2. The speed of the rotating blades changes with the natural wind speed, so the rotor of the turbine generator inevitably has uneven speed; at the same time, the turbine generator must have a high starting wind speed
[0008] 3. Human beings cannot control the strength of these winds, so wind turbines (including supporting iron frames and towers) must be strong enough to be able to operate safely under various natural conditions, which undoubtedly increases the wind power. investment costs for power generation;
[0009] 4. Since wind power stations are generally built in remote areas, it is necessary to erect long-distance power transmission and transformation lines and facilities, which will undoubtedly increase investment costs
[0010] 5. In cities and towns that most need power supply, due to the poor availability of wind power, the wind direction often becomes fluctuating, and air turbulence will wear out the turbines, resulting in low operating efficiency of wind turbines installed in cities and towns
[0011] In addition, there are still a lot of energy (including waste energy) in daily life that has not been fully utilized and wasted.
For example, in hot summer, the surface temperature of open-air objects (such as highway asphalt roads, airport cement roads, squares, building exterior walls, roofs, etc.) is relatively high, and sometimes people have to spray water for instant cooling, which wastes heat. ; Another example is affected by the thermal radiation of molten steel (or boiler), the temperature in the steelmaking (or boiler) workshop is very high, and workers sometimes have to take measures to immediately cool down, and these heats are not fully utilized and are used in vain. waste; and for example, in summer (winter) season, many buildings use air conditioners or heat pumps to adjust the temperature indoors, while air-cooled air conditioners or heat pumps will directly discharge the waste heat (cold) gas generated by indoor temperature adjustment into The atmosphere has not been fully utilized, and the exhaust gas flow may also have an impact on the surrounding area; for example, hot springs and geothermal heat in the natural world have produced a large amount of heat for many years, and have not been fully utilized by humans.

Abstract

The invention relates to an airflow generating system and a method thereof. The system comprises an air source, a passage, at least an unpowered air draft device and at least a turbine generator set, wherein, the passage comprises an airflow inlet and an airflow outlet which are communicated with the air source; the unpowered air draft device is installed at the airflow outlet and is positioned in a natural wind field; the turbine generator set at least comprises rotating blades positioned in the passage; and driven by the airflow of the air source and / or the external wind power, the unpowered air draft device forms the negative pressure in the passage, and constantly sucks in air from the air source to form the airflow in the passage, and the airflow pushes the rotating blades to rotate so as to drive the turbine generator set to generate electricity. The system of the invention can constantly run, stably generate electivity, lower the dependence on weather and overcome the unicity and the limitation of clean energy of single type.

Description

technical field [0001] The present invention relates to a system and method for generating electricity by utilizing airflow, more specifically, relates to a system and method for generating electricity by effectively utilizing thermal temperature difference, airflow generated by pressurized gas, or / and natural wind (including breeze) systems and methods. Background technique [0002] With the rapid development of the economy, the shortage of fossil fuels such as coal and oil frequently appears. The depletion of these non-renewable energy sources is a cruel reality that human beings have to face. The bottleneck restricting social and economic development. [0003] At present, the relatively common clean energy power generation mainly focuses on solar power generation and wind power generation. However, relying on a single type of clean energy for power generation has certain limitations. [0004] Although solar photovoltaic power generation technology has matured, due to th...
