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
The present invention relates to the defroster that keeps out the wind of power plant's cooling tower, relate in particular to the cooling tower antifreezing deep bead.
Background technology
At northern frore area, to hyperbolic natural-draft cooling tower the anti-ice facility of hanging must be set, otherwise, cooling tower will cause serious extension ice phenomenon, cause packing in the cooling tower, carriage is dragged and part trickle Structure Beam-column causes and seriously freezes molten dew muscle, make normally safe operation of cooling tower, more can not effectively control the water temperature in the cooling tower.For a long time, people adopt the method for building windbreak around cooling tower to solve antifreeze problem usually, and described windbreak is made up of framework and deep bead, and deep bead is hung solid on framework by the mode of artificial suspension.In arriving winter, need build the high-altitude installing rack, solid on framework by manually the deep bead block-by-block being hung, perhaps install by high-altitude operation vehicle; When after winter, again deep bead block-by-block from the framework is removed, and collection takes good care of, be convenient to utilize again the coming year.Because the quantity of deep bead is many, volume is big, heavier, the artificial suspension of annual deep bead, the workload of excision are very big, not only labour intensity is big, holding time is many, and artificial high-altitude application is also dangerous, is easily damaged in deep bead, the excision process solid at frequent extension simultaneously, maintenance cost height, result of use are difficult to guarantee.
Along with the fast development of China's electric utility, large cooling column is on the increase, and the air inlet height of cooling tower also increases to some extent, and the length of deep bead and weight also increase thereupon, and this brings bigger difficulty to the anti-ice facility of hanging of cooling tower, and operating cost will further increase.Do not hang ice winter in order to ensure cooling tower, under the prerequisite of the antifreezing effect that guarantees anti-extension ice facility, avoid repeating to hang admittedly and extracing of deep bead, reduce operating cost, eliminate the deep bead high-altitude and hang the hidden danger that exists in solid and the excision operation, make the anti-ice facility of hanging of cooling tower can play the anti-antifreeze effect of ice of hanging in the winter time, can guarantee good performance of ventilating again in other season, the applicant has successfully developed a kind of automatic starting and closing type anti-freezing device of wind screen of cooling tower, and it has solved the problems referred to above well.And deep bead is one of vital part wherein.
Summary of the invention
The purpose of this invention is to provide a kind of cooling tower antifreezing macromolecule wind screen.
Described cooling tower antifreezing macromolecule wind screen is the hollow sheeting equipment structure, it by around wall body, groove and reinforcement form, the thickness of wall body is 2～4 millimeters all around, the thickness of reinforcement is 2～5 millimeters.
Further, the wide of deep bead is 300～500 millimeters, and thickness is 15～50 millimeters.
Further, the cross sectional shape of described groove is the rectangle of band fillet.
Further, the deep bead material is high molecule plastic or fiberglass.
Specification requirement of the present invention is:
1. bearing capacity is 〉=650N/m
2
2. mid-span deflection≤1/120;
3. through broadwise bending strength 〉=32Mpa.
4. profile is smooth, and surface color is even, does not have the variable color of decomposition line, and is smooth, defectives such as flawless and bubble.
The deep bead of this structure can adopt extruder for shaping, and physical dimension is stable, and the mechanical strength height is from heavy and light, move light, bearing capacity is strong, mechanical property excellence, non-environmental-pollution, production mechanization degree height, and can secondary recovery utilize again, neat appearance, with low cost.
Description of drawings
The structural representation of the present invention that Fig. 1 is,
Among the figure: wall body around the 1-; The 2-groove; The 3-reinforcement.
The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention:
Described cooling tower antifreezing macromolecule wind screen, as shown in Figure 1, it is the hollow sheeting equipment structure, by wall body 1, groove 2 and reinforcement 3 are formed all around, plate is wide to be 500 millimeters, 30 millimeters of thicknesss of slab, the thickness of wall body 1 is 3 millimeters all around, the thickness of reinforcement 3 is 3 millimeters, the cross sectional shape of groove 2 is the rectangle of band fillet, and the length of left and right sides groove 2 is 30 millimeters, and the length of all the other grooves 2 is 44 millimeters, and the deep bead material is high molecule plastic or fiberglass.
Above-mentioned deep bead is by the double screw extruder extrusion molding, and physical dimension is stable, the mechanical strength height.The technical parameter of gained deep bead is: bearing capacity 〉=650N/m
2Mid-span deflection≤1/120; Through broadwise bending strength 〉=32Mpa; Profile should be smooth, and surface color is even, do not have the variable color of decomposition line, and is smooth, defectives such as flawless and bubble.
