In some embodiments, the relationship between the optimal sonic frequency and the radius of the water mist particles satisfies equation (i):
wherein eta is the shear viscosity coefficient of the gas, ρ p The density of the water mist is shown, and a is the radius of the water mist particles.
In some embodiments, the flue gas water extraction and whitening method is carried out, and the flue gas flow rate is 20-30 m/s; the inlet temperature of cold fluid in the flue gas heat exchange tube is less than 25 ℃.
Example 1
As shown in fig. 1 and 2, the water lifting and whitening device comprises a bellows type shell 4, wherein a smoke inlet 1 is arranged at the top of the bellows type shell 4, and the lower end of the smoke inlet 1 is connected with a plurality of smoke flow dividing plates 2. The bottom of the bellows type shell 4 is cone-shaped, and the bottommost end of the cone-shaped part is a water outlet 6. The bellows housing 4 is provided with a flue gas outlet 5 immediately adjacent to the upper port of the cone-shaped portion.
A plurality of groups of flue gas heat exchange tubes 3 are densely arranged between the flue gas splitter plate 2 and the flue gas outlet 5; each group of flue gas heat exchange tubes 3 is provided with a cooling water inlet 3-1 and a heat exchange water outlet 3-2.

According to the method for extracting water and whitening the smoke by adopting the water extraction and whitening device, smoke with the flow rate of 20-30m/s enters the bellows type shell 4 from the smoke inlet 1, and the smoke is split by the smoke splitter plate 2 and then fully exchanges heat with the smoke heat exchange tube 3, so that the temperature is effectively reduced, the water vapor in the smoke is efficiently condensed, and water mist is separated; meanwhile, the bellows type shell 4 regularly contracts and expands the flowing smoke, and emits sound waves to agglomerate the condensed water mist; the agglomerated fog drops slide down or vertically fall down on the wall surface under the action of gravity and are discharged out of the device through the water outlet 6; the smoke after removing the water mist is discharged out of the device through a smoke outlet 5.

Because each parameter of the flue gas is not necessarily fixed in the operation of the corrugated pipe, the accurate calculation of the pitch of the corrugated pipe is difficult.
As one implementation mode, the corrugated pipe joint spacing is designed in a sectional mode according to a formula, the joint spacing on each section is equal, the difference is arranged on different sections, and the joint spacing of each section is gradually increased along the advancing direction of the flue gas.
