The demister 9 includes a first fin 901, a second fin 903, and at least one support plate 902, the first fin 901 and the second fin 903 each have an elongated plate shape, and the lengths of the first fin 901 and the second fin 903 are substantially the same as the length of the straight pipe 801.

The first side end of the first fin 901 is welded on the side of the coil pipe 8, the second fin 903 is higher than the first fin 901, the bottom end of the supporting plate 902 is welded on the upper surface of the first fin 901, the top end of the supporting plate 902 is welded on the lower surface of the second fin 903, and a ventilation channel is formed between the first fin 901 and the second fin 903.

Since the first fins 901, the second fins 903 and the supporting plate 902 are all heat dissipation fins, they can be specifically copper flakes, aluminum alloy flakes or brass flakes. In this embodiment, a copper sheet is preferable.

The hot water flowing through the straight tube 801 can make the temperature of the straight tube 801 higher, and the first fin 901 dissipates heat of the straight tube 801, heat on the first fin 901 is conducted to the supporting plate 902, and then is conducted to the second fin 903 through the supporting plate 902, so that heat dissipation can be performed on the straight tube 801 rapidly through the heat dissipation of the first fin 901, the second fin 903 and the supporting plate 902, and then the hot water in the straight tube 801 can be primarily cooled.

As a preferred embodiment, the first side end of the first fin 901 is higher than the second side end of the first fin 901, the first fin 901 is welded to the straight tube 801 in an inclined manner, the first side end of the second fin 903 is located directly above the first fin 901, the downward projection of the second side end of the second fin 903 does not fall onto the first fin 901, the bottom end of the support piece 902 is welded to the right end of the first fin 901, and the top end of the support piece 902 is welded to a position of the second fin 903 close to the first side end.

Further, a plurality of support pieces 902 are provided, the plurality of support pieces 902 are provided in order along the length direction of the first fin 901, and a ventilation gap is formed between two adjacent support pieces 902. Specifically, the distance between two adjacent support pieces 902 is the same, i.e., the support pieces 902 are uniformly welded to the first fins 901, so that the length of the ventilation gap is fixed.

Outside air enters the tower body 1 from the air inlet 101 at the bottom of the tower body 1, the wind blown in from the lower part of the cooling tower and hot water sprayed from top to bottom form convection, a part of water evaporates in the convection and takes away corresponding latent heat of evaporation, so that the temperature of the water is reduced, in the convection contact heat exchange process, liquid mist drops are entrained by air flow to move towards the demisting cooling assembly 5, the gas containing the liquid mist flows through the demisting cooling assembly 5 at a certain speed, and due to the inertia impact effect of the gas, the liquid drops which are accumulated due to collision of the mist with the first fins 901 and the second fins 903 are separated from the surfaces of the first fins 901 and the second fins 903 when the gravity generated by the liquid drops exceeds the resultant force of the lifting force of the gas and the surface tension of the liquid.

Further, since the first side end of the first fin 901 is higher than the second side end of the first fin 901, and the first side end of the second fin 903 is located directly above the first fin 901, the projection of the second side end of the second fin 903 toward the lower side does not fall onto the first fin 901. Thus, the gas bypasses the first fins 901, and as a part of the gas is blocked by the second fins 903, the gas flows out from the ventilation passage between the first fins 901 and the second fins 903. Further, since the first side end of the second fin 903 is higher than the second side end of the second fin 903, that is, the second fin 903 is also inclined, and the second fin 903 is parallel to the first fin 901, a portion of the gas is directly blocked by the second fin 903 and enters into the ventilation channel along the lower surface of the second fin 903.

The first fins 901 and the second fins 903 are set to be inclined, which is more favorable for the aggregation of the liquid drops, thereby accelerating the separation rate of the liquid drops and being more favorable for the rapid rising and discharging of the gas.

Specifically, as shown in one demister 9 located on the right side of the straight tube 801 in fig. 4, the left side end of the first fin 901 is welded to the straight tube 801 with the left side end of the first fin 901 lower than the right side end thereof and the left side end of the second fin 903 higher than the right side end of the second fin 903, and the first fin 901 and the second fin 903 are parallel.

Preferably, as shown in fig. 4, two demisting pieces 9 are welded on each straight pipe 801, the two demisting pieces 9 are symmetrically arranged about the axis of the straight pipe 801, one demisting piece 9 is welded on the left side of the straight pipe 801, and the other demisting piece 9 is welded on the right side of the demisting piece 9. Thus, the space is fully utilized, the trapping area can be increased as much as possible, and the trapping efficiency of mist is improved.

The first fin 901 and the second fin 903 are in an intersecting state.

After the gas containing mist located right under the first fins 901 impinges on the first fins 901, the gas rises along the first fins 901 without bypassing the first fins 901, and the gas further enters the ventilation passage along the second fins 903 due to the blocking action of the second fins 903. Thus, the gas can enter the ventilation channel faster and more smoothly to be discharged.

As an alternative embodiment, fig. 6 is a third structural diagram of a straight tube 801 and demister 9, wherein one demister 9 is welded to each side of the straight tube 801, wherein in the demister 9 located on the left side of the straight tube 801, the right side end of a first fin 901 is welded to the straight tube 801, the right side end of the first fin 901 is higher than the left side end of the first fin 901, and the left side end of a second fin 903 is higher than the right side end of the second fin 903.
