Description
Technical field
The utility model is a kind of gas-cooker waste heat from tail gas pulsating heat pipe hot water using pulsating heat pipe as heat transfer element
Pot, belong to pulsating heat pipe field of waste heat utilization application technology.
Technical background
With the fast development of China's economy, energy problem day is becoming tight, and environmental problem form also becomes severe, this makes
The high efficiency of the energy, the requirement of spatter property increasingly improve in society, and the cry of energy-saving and emission-reduction is anticipated along with people's energy conservation and environmental protection
The enhancing of knowledge is gradually paid attention to.Thermal energy is the highest energy of demand in China's development, therefore annual heat-energy losses are also phase
When considerable.China is applied for the research of waste heat recovery mainly in steam power plant at present, the large-scale hot enterprise such as paper mill,
And for common hotel, the waste heat of compact heat source (predominantly gas-cooker) generation in the places such as dining room and residential households is not
It is effectively recycled and is utilized, at a rough estimate, the heat of annual therefore loss is also huge.
Widely used gas-cooker has commercial large stove, Chinese meal stove and a domestic range etc. in the market, large stove therein and
Tail gas after Chinese meal stove generally burning is directly passed to the cold water in pot by residual heat flue with convection current heat transfer type, but waste heat returns
Receipts utilize extremely inefficient, and domestic range is because using Open architecture, and waste heat from tail gas is even more that could not be recycled and utilize, and is caused
The thermal efficiency of entire gas-cooker is relatively low, and not more than 55%.This also means that waste heat from tail gas heat in this type gas combustion apparatus
Loss is very high, and the thermal energy after fuel gas buring does not obtain due efficient utilization.
Pulsating heat pipe is a kind of small-sized efficient heat transfer element, has heat transfer efficiency high, adaptable, plasticity is good excellent
Point.The manufacture of pulsating heat pipe and application technology are increasingly ripe, and its relative inexpensiveness.Regrettably these technical products are remaining
Application is not promoted largely in terms of recuperation of heat.The present apparatus is exactly the performance advantage using pulsating heat pipe, for commercialization
The high-temperature tail gas generated with heat sources such as civilian sealed gas firing ranges carries out waste heat recovery, achieves energy-saving and emission reduction purposes.
