Description
Technical field
It the utility model is related to water heater arrangement technical field, more particularly to a kind of solar energy based on flow solids particle
High temperature air heat dump.
Background technology
Because the reserves of the fossil energies such as coal, oil, natural gas are limited, and largely cause global gas using fossil energy
Time warms, atmosphere pollution, ecological degeneration, environment for the survival of mankind is by unprecedented challenge, traditional fossil energy hair
Status of the power technology in energy supply field is increasingly under suspicion；And with the development of nuclear power technology, also occur in recent years
Carry out the nuclear leakage event on the ground such as Fukushima, not only harmed our electrical safety, more threatened the life and health of the mankind.
The processing mode of nuke rubbish, the even more mankind pendent problem always.Nuke rubbish is once produced, and its radiation will be in future
The health of the mankind is threatened in more than 200 ten thousand years.By contrast, it is undoubtedly more reliable and energy-saving, ring using solar power generation
