Description
Technical field
The present invention relates to a kind of efficient hot swapping of turbulent heat transfer, in particular to the flue gas gas of a kind of heat recovery
Water heat exchanger.
Background technique
In industrial flue gas during smelting processing system, have since the exhaust gas volumn that system generates is big, and when flue gas discharge higher
Flue-gas temperature results in flue gas and is released in atmosphere containing more waste heat, on the one hand causes biggish energy dissipation,
Still further aspect also results in thermal pollution.Efficiently use another of realization energy-saving and emission-reduction of the fume afterheat at each enterprise
Mode, wherein generating hot water using flue gas heat exchange is the most common heat recovery method.In the case where not increasing new investment, mention
High heat exchange efficiency while reinforcing recuperation of heat, improves flue-gas temperature, reduces hot water and flue-gas temperature difference is the mesh that system is pursued
Mark.
Summary of the invention
The technical problem to be solved by the present invention is provide a kind of efficient hot swapping of turbulent heat transfer, high temperature flue gas into
Enter to after blast pipe, flue gas is evenly distributed to the windward side of heat exchange fin by flue gas distributor, heat exchange fin is waveform
There is smaller difference in structure, local flow channel section, and on the one hand which realizes flue gas in heat transfer process, the flowing between fin
Speed is substantially uniform, simultaneously because the effect of waveform configuration, promotes flue gas to form small-sized whirlpool between fin, change flue gas with
The boundary layer structure of fin, improves heat exchange property, strengthens heat transfer effect.
The technical solution of the present invention is as follows: a kind of efficient hot swapping of turbulent heat transfer, including air to water heat exchanger cabinet, gas
There is blast pipe in water heat exchanger cabinet side, and there is discharge pipe in the other side, and blast pipe has air inlet, has smoke distribution in blast pipe
Device, discharge pipe have air outlet, there is circulation water coil in air to water heat exchanger cabinet, recycle and are fixed with heat exchange fin on water coil.
Have flue gas distributor in blast pipe, flue gas distributor flue gas can be evenly distributed to heat exchange fin it is entire windward
On face, heat exchange fin windward side flue gas flow rate is avoided larger difference occur.
Heat exchange fin uses waveform configuration, and when flue gas enters between heat exchange fin, heat exchange fin disperses flue gas, together
When due to waveform configuration effect, promote flue gas to form small-sized vortex between heat exchange fin, flue gas between heat exchange fin to
It while preceding flowing, rolls between heat exchange fin, destroys the stability of wall layer, strengthen changing for flue gas and heat exchange fin
Thermo-contact improves heat exchange efficiency.
Spacing between heat exchange fin is slightly changed, which strengthens the perturbation action of flue gas, in terms of another
Wall layer stability is destroyed, but the resistance that equipment forms flue gas varies less, i.e., while resistance is basicly stable, improves
Equipment heat exchange property.
Compared with the prior art, by the way that existing plate fin structure is changed to waveform configuration, fin changes the present invention
Flow passage structure is changed by flow passage structure, is realized flue gas turbulent heat transfer, is improved the heat exchange performance of flue gas, while passing through flue gas
Distributor controls the flowing velocity and flow direction that flue gas enters heat exchange area, reinforces the uniformity of equipment heat exchange, preferably realizes
Exchange heat target, reinforces heat recovery, reduces enterprise operation cost, preferably realizes the target of energy-saving and emission-reduction, therefore this
Invention has good promotional value and use value.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The efficient hot swapping of turbulent heat transfer of the invention, by blast pipe be arranged flue gas distributor, control flue gas into
Enter the flowing velocity and flow direction of heat exchange area, reinforces the uniformity of equipment heat exchange；Existing plate fin structure is changed to wave
Shape structure, fin change flow passage structure, are changed by flow passage structure, and great quantity of small whirlpool is formed when flowing flue gas in runner,
Vortex pair wall surface forms souring, changes flue gas wall layer structure, realizes flue gas turbulent heat transfer, improves the heat exchange of flue gas
Can, reduce temperature difference between air water, reinforce heat recovery, reduces enterprise operation cost, preferably realize energy conservation object.
The efficient hot swapping of the turbulent heat transfer designed based on the above reasons, as shown in Figure 1, including air to water heat exchanger case
There are a blast pipe 2 in body 1,1 side of air to water heat exchanger cabinet, and there is a discharge pipe 3 in the other side, and blast pipe 2 has an air inlet 4, in blast pipe 2
There is flue gas distributor 6, discharge pipe 3 has air outlet 5, has circulation water coil 7 in air to water heat exchanger cabinet 1, recycles on water coil 7
It is fixed with heat exchange fin 8.
In use, flue gas enters in blast pipe 2 from air inlet 4, the flue gas distributor 6 in blast pipe 2
Under effect, flue gas is evenly distributed to the windward side of heat exchange fin 8, and even into in the runner between heat exchange fin 8, by
It being designed in the waveform configuration and bend flow channel cross section structure of heat exchange fin 8, flue gas forms that small-sized vortex is dynamic and turbulent flow in runner,
Strong convection heat exchange is formed, the flue gas after heat exchange enters discharge pipe 3 and enters flue discharge by air outlet 5.
