[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A cooling tower air duct comprises an air duct body 1, a water guide mechanism 2 for making full use of rainwater is arranged outside the air duct body 1, and a disassembly assembly 3 for cleaning dust on the outer wall of the air duct body 1 is arranged inside the water guide mechanism 2;

[0031] The water guide mechanism 2 includes an arc ring 201, a filter plate 202, a groove 203 and a water inlet groove 204. The arc ring 201 is bolted to the outer wall of the air duct body 1, the filter plate 202 is bolted to the inner wall of the arc ring 201, the groove 203 is opened at the top of the arc ring 201, and the water inlet groove 204 is opened on the outer wall of the air duct body 1. The number of the grooves 203 and the water inlet grooves 204 are both several and are distributed circumferentially. One end of the filter plate 202 is bolted to the outer wall of the air duct body 1, and the filter plate 202 is arranged at an angle.

[0032] Specifically, Figure 5 As shown, a fixing ring 4 is welded on the inner wall of the air duct body 1, a mounting ring 5 is bolted to the top of the fixing ring 4, a slope 6 is arranged on the top of the mounting ring 5, and a plurality of groups of inclined air guide plates 7 are distributed circumferentially on the side wall of the mounting ring 5.

[0033] Specifically, Figure 5 As shown, two collecting rings 8 for collecting micro particles in rainwater are evenly distributed on the inner wall of the arc-shaped ring 201, and one end of the collecting ring 8 is convex.

[0034] Specifically, Figure 5 As shown, a guide ring 9 for guiding rainwater is welded to the bottom of the filter plate 202, and the cross-sectional shape of the guide ring 9 is a right triangle.

[0035] Specifically, Figure 1 As shown, a filter screen 10 for blocking dust in the outside air is bolted to the bottom of the air vent body 1, and the filter screen 10 is made of stainless steel.

[0036] Specifically, Figure 1 As shown, an anti-corrosion layer and a wear-resistant layer are sprayed on the inner wall and the outer wall of the air duct body 1, respectively. The anti-corrosion layer and the wear-resistant layer are made of phenolic resin paint and epoxy wear-resistant paint respectively.

[0037] Specifically, Figure 1 As shown, a disassembly plate 11 is welded on the outer wall of the filter plate 202 for facilitating disassembly of the filter plate 202 .

[0038] When in use, rainwater from the outside will enter the interior of the air duct body 1 through the filter plate 202 and the groove 203. At this time, the filter plate 202 and the groove 203 can both play a filtering effect. When there are many solid particles in the rainwater or foreign debris falls on the filter plate 202, because the filter plate 202 is tilted, and the groove 203 and the filter plate 202 can both play a filtering effect, the solid particles or debris will be directly blown down when they come into contact with the wind, preventing the accumulation of debris and affecting the normal filtering of rainwater. The filtered rainwater is guided to the collecting ring 8 by the guide ring 9. The protrusion at one end of the collecting ring 8 can cause tiny particles to accumulate, thereby further improving the cleanliness of the rainwater and preventing the water inlet groove 204 from being blocked, which can improve the heat exchange effect of the air duct. Then the tilted air guide plate 7 can guide the air entering the interior of the air duct body 1 and can also slow down the air flow rate, so that the air and liquid can fully contact each other, thereby improving the heat exchange efficiency.

[0039] Specifically, Figure 4 As shown, the disassembly and assembly component 3 includes four arc grooves 301, four sealing plates 302 and a plurality of bolts 303, the four arc grooves 301 are evenly distributed on the outer wall of the arc ring 201, the four sealing plates 302 are inserted into the interior of the arc grooves 301, and the plurality of bolts 303 are threadedly connected to the interior of the sealing plates 302, and one end of the plurality of bolts 303 extends to the interior of the arc ring 201 and is threadedly connected to the arc ring 201.

[0040] When the water inlet groove 204 is blocked, the user can unscrew the bolt 303, then remove the sealing plate 302, and then use a tool to successively penetrate the arc groove 301 and the inside of the water inlet groove 204 to dredge the water inlet groove 204. At the same time, the small gap between the bottom end of the arc ring 201 and the outer wall of the air duct body 1 can be cleaned, which is convenient for the user to operate.

[0041] By adopting the above technical solution, the problem that the existing cooling tower air duct can only block solid particles or debris in rainwater through the annular mesh plate when in use is solved. When a lot of debris accumulates on the annular mesh plate, it will affect the normal entry of rainwater into the water collection bucket, thereby affecting the normal use of the equipment.

[0042] Working principle: When in use, rainwater from the outside will enter the interior of the air duct body 1 through the filter plate 202 and the groove 203. At this time, the filter plate 202 and the groove 203 can both play a filtering effect. When there are many solid particles in the rainwater or foreign debris falls on the filter plate 202, because the filter plate 202 is tilted, and the groove 203 and the filter plate 202 can both play a filtering effect, the solid particles or debris will be directly blown down when they come into contact with the wind, preventing the accumulation of debris and affecting the normal filtration of rainwater. The filtered rainwater is guided to the collection ring 8 by the guide ring 9. The protrusion at one end of the collection ring 8 can cause tiny particles to accumulate, thereby further improving the rainwater Cleanliness, prevent the water inlet groove 204 from being blocked, and can improve the heat exchange effect of the air duct. Then the inclined air guide plate 7 can guide the air entering the air duct body 1 and also slow down the air flow rate, so that the air and liquid can be fully in contact, thereby improving the heat exchange efficiency. When the water inlet groove 204 is blocked, the user can unscrew the bolt 303, then remove the sealing plate 302, and then use tools to pound the arc groove 301 and the water inlet groove 204 in turn, so as to dredge the water inlet groove 204, and at the same time, the small gap between the bottom end of the arc ring 201 and the outer wall of the air duct body 1 can be cleaned, which is convenient for users to operate.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
