Problems solved by technology

In order to ensure that the cooling tower does not hang ice in winter, on the premise of ensuring the antifreeze effect of the anti-icing facilities, avoid repeated fixing and removal of the windshield, reduce operating costs, and eliminate the problems existing in the high-altitude fixing and removal of the windshield. Unsafe hidden danger, so that the anti-icing facilities of the cooling tower can play the role of anti-icing and anti-freezing in winter, and can ensure good ventilation performance in other seasons. The applicant successfully developed an automatic opening and closing windshield anti-freezing of the cooling tower device, which solves the above problems well

specific Embodiment approach

[0018] The cooling tower antifreeze polymer windshield, such as figure 1 As shown, it is a hollow plate structure, which is composed of a surrounding wall body 1, a hollow groove 2 and a reinforcing rib 3. The width of the plate is 500 mm, and the thickness of the plate is 30 mm. The cross-sectional shape of the hollow slot 2 is a rectangle with rounded corners, and the length of the hollow slots 2 on the left and right sides is 30 mm, and the length of the remaining hollow slots 2 is 44 mm. The material of the windshield is polymer plastic or fiberglass .

[0019] The above-mentioned windshield is extruded by a twin-screw extruder, and has stable structural dimensions and high mechanical strength. The technical parameters of the obtained windshield are: bearing capacity ≥ 650N / m 2 ; Mid-span deflection ≤ 1 / 120; Longitude and latitude bending strength ≥ 32Mpa; The shape should be flat, the surface color should be uniform, no decomposition and discoloration lines, smooth, no ...

Abstract

The invention discloses a cooling tower antifreezing macromolecule wind screen which is a hollow board structure and composed of peripheric wall body, a hollow groove and a reinforcing rib, wherein the thickness of the peripheric wall body is 2-4 mm, and the thickness of the reinforcing rib is 2-5 mm; the width of the wind screen is 300-500 mm, and the thickness is 15-50 mm; the wind screen is made of macromolecule plastics or glass fiber reinforced plastics; The wind screen with the structure can be extruded and shaped by an extruder, has stable structure and size, high mechanical strength, light dead weight, light operation, strong loading capacity, excellent mechanical property, no environment pollution, high production mechanization degree and low cost, can be recovered and reused and is tidy and beautiful.

Description

technical field [0001] The invention relates to a windshield and antifreeze device for a cooling tower of a power plant, in particular to an antifreeze windshield for a cooling tower. Background technique [0002] In the severe cold regions of the north, anti-icing facilities must be installed for hyperbolic natural ventilation cooling towers, otherwise, the cooling tower will cause serious ice-hanging phenomenon, resulting in water-splashing fillers, brackets falling and part of the water-spraying structural beams in the cooling tower Severe freezing and thawing of the exposed ribs caused by the column makes the cooling tower unable to operate normally and safely, let alone effectively control the water temperature in the cooling tower. For a long time, people have usually adopted the method of building a windshield around the cooling tower to solve the antifreeze problem. The windshield is composed of a frame and a windshield, and the windshield is hung on the frame by art...
