More backhauls, it is bulky.And in many cases, in thermal current all can dust-laden, it is stifled that thermal current dust-laden be easy to cause heat exchanger
Plug.
For at this stage, due to the influence of temperature difference correction factor, the total heat transfer efficiency of traditional gas plate heat exchanger
Can be low, and deashing is more difficult so that system after reducing energy consumption can not stable operation, and when flue-gas temperature is relatively high,
Also the cleaner of the better dust removal effects such as sack cleaner and electrostatic precipitator can not be used to shift to an earlier date dedusting to flue gas, and it is common
Whirlwind or 5 microns of multi-tube dust cleaner pair fine dusts removal rate below are relatively low；Such as use broad passage plate heat exchanger, equipment knot
Dirty stopping state can be alleviated, but waste heat recovery effect is then had a greatly reduced quality, and reason is：Plate channel is excessive, and unit is horizontal
The quantity of heat exchange plate will be greatly decreased in the flue gas flow channel of sectional area, and heat exchange area is insufficient, and expected energy-saving effect is not achieved；
Flue gas flow channel sectional area is such as significantly increased in the case where heat exchange area is constant, then flow velocity of the flue gas in heat exchanger substantially under
Drop, flow velocity decline cause overall heat-transfer coefficient K substantially to reduce, and expected energy-saving effect is still not achieved, and industry energy conservation transformation exists
It is exactly Mist heat recovering to increase the purpose of heat exchanger in smoke evacuation system.
Therefore, flue gas waste heat recovery field is there is an urgent need for a kind of structure type is simply novel, and heat transfer efficiency is high and deashing is convenient
Heat exchanger.
