Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling tower accessories, in particular to a cooling tower anti-sand and dust-proof air and water guiding air inlet window. Background Art
[0002] Cooling towers are used to cool high-temperature water in different industries. The top fan rotates and introduces ambient air through the lower air inlet window. The ambient air comes into contact with the cooling water in the heat dissipation filler, and part of the cooling water evaporates, which reduces the temperature of the water. The hot and humid air is discharged by the top fan. In order to prevent the cooling water from splashing out of the tower through the air inlet window, a downward-sloping water guide plate is installed on the air inlet window to guide the splashing water droplets into the tower. However, in windy and sandy areas, the water guide plate has the following main disadvantages: since cooling towers are generally installed outdoors, and the common water guide plates on the market have a simple structure and a single function, but the air flow velocity at the air inlet window is high, in windy and sandy areas, foreign matter such as sand and dust can easily enter the cooling tower with the air flow and accumulate in the cooling tower water collection tank, causing blockage and damage to the heat exchanger, affecting the normal operation of the equipment. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a cooling tower anti-sand and dust wind and water guide air inlet window, which solves the problem that foreign matter such as sand and dust can easily enter the interior of the cooling tower with the air flow.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling tower dust-proof wind and water guide air inlet window, comprising an air inlet window frame, wherein a plurality of groups of dust-proof wind and water guide plates are longitudinally arranged inside the air inlet window frame, and the dust-proof wind and water guide plates are integrally composed of dust-proof wind guide plates and wind window water guide plates, and the connection between the dust-proof wind guide plates and the wind window water guide plates constitutes a convex structure, and the bottoms of the dust-proof wind guide plates and the wind window water guide plates are both provided with vertically downward extension sections.
[0005] Preferably, the anti-sand and dust air guide plate is an arc-shaped plate, and one side of the arc-shaped concave surface of the anti-sand and dust air guide plate faces the outside of the cooling tower.
[0006] Compared with the prior art, the utility model provides a cooling tower anti-sand and dust wind and water guide air inlet window, which has the following beneficial effects:
[0007] The cooling tower's anti-sand and dust air and water inlet window is improved on the basis of the original air inlet window water guide plate, and an arc-shaped anti-sand and dust air guide plate structure is added, which is designed as one of the original wind window water guide plates. When the high-speed air flow entering the tower contains sand, dust and foreign matter, the sand, dust and foreign matter will hit the arc-shaped anti-sand and dust air guide plate with the air flow, gather on the arc-shaped anti-sand and dust air guide plate, and slide down the anti-sand and dust air guide plate to the outside of the cooling tower under the action of gravity. Therefore, it avoids sand, dust and other foreign matter from entering the tower and causing blockage and damage to the heat exchanger, affecting the normal operation of the equipment, thereby ensuring the normal operation of the device.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0013] See also Figure 1-3 The utility model provides a technical solution: a cooling tower anti-sand and dust air guide and water guide air inlet window, including an air inlet window frame 1, characterized in that: a plurality of groups of anti-sand and dust air guide and water guide plates 2 are longitudinally arranged inside the air inlet window frame 1, and the anti-sand and dust air guide and water guide plates 2 are integrally composed of anti-sand and dust air guide plates 201 and wind window water guide plates 202. The connection between the anti-sand and dust air guide plates 201 and the wind window water guide plates 202 forms a convex structure, and the anti-sand and dust air guide plates 201 are arc-shaped plates, and the arc-shaped concave side of the anti-sand and dust air guide plates 201 faces the outside of the cooling tower. The arc-shaped anti-sand and dust air guide plates 201 can buffer the airflow entering the tower, prevent the high-speed airflow entering the tower from affecting the normal use of the structure inside the tower, make the airflow entering the tower smoother, and the dust contained in the airflow The dust-proof wind deflector 201 and the windscreen water guide plate 202 are both provided with downward vertical extension sections at the bottom. The top of the connection between the dust-proof wind deflector 201 and the windscreen water guide plate 202 and the bottom of the extension section of the dust-proof wind deflector 201 above it are at the same horizontal height. Thus, the extension section can block the direct blowing of dust and other debris, further preventing dust and other foreign matter from entering the cooling tower, and the high-speed airflow will be buffered and introduced into the tower along the dust-proof wind deflector 201, so that the high-speed airflow enters the tower evenly under the rectification of the dust-proof wind deflector 201.
[0014] The working principle is that before the air flow enters the cooling tower, it will first contact the dust-proof air guide plate 201. The dust and other debris in the air flow will be blocked by the dust-proof air guide plate 201 and its bottom extension section, and then will slide down along the dust-proof air guide plate 201 to the outside of the cooling tower under the action of gravity. At the same time, the air flow will be buffered by the curved dust-proof air guide plate 201, so that the air flow and residual dust will tilt upward along the two sets of dust-proof air guide plates 201 and contact the wind window water guide plate 202. At this time, the residual dust will be blocked by the wind window water guide plate 202, further preventing foreign matter such as dust from entering the tower and causing blockage and damage to the heat exchanger, thereby affecting the normal operation of the equipment. At the same time, the air flow is buffered again and enters the cooling tower evenly along the two sets of wind window water guide plates 202. At the same time, when the coolant in the tower splashes, it will be blocked by the wind window water guide plate 202 and its bottom extension section, and then fall downward along the wind window water guide plate 202, preventing the coolant from splashing out of the tower through the air inlet window frame 1.
[0015] The cooling tower's anti-sand and dust-proof air and water guide air inlet window is improved on the basis of the original air inlet window water guide plate, and an arc-shaped anti-sand and dust-proof air guide plate 201 structure is added. It is designed as an integral whole with the original air window water guide plate 202 and is installed on the air inlet window frame 1. When the high-speed air flow into the tower contains sand, dust and foreign matter, the sand, dust and foreign matter collide with the arc-shaped anti-sand and dust-proof air guide plate 201 with the air flow, gather on the arc-shaped anti-sand and dust-proof air guide plate 201, and slide down to the outside of the cooling tower along the anti-sand and dust-proof air guide plate 201 under the action of gravity. Therefore, it avoids sand, dust and other foreign matter from entering the tower and causing blockage and damage to the heat exchanger, affecting the normal operation of the equipment, thereby ensuring the normal operation of the device.
[0016] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
