Abstract
The utility model relates to a hyperbola cooling tower defroster, including a circulation return pipe, a water supply pipe and a spray pipe, wherein, the lower end of the water supply pipe is connected to the cooling tower circulation return pipe, and the upper end is connected to the spray pipe arranged with spout holes. The implementation of the utility model can totally eliminate the cooling tower bottom icing phenomenon so that the dry low-temperature air can continuously flow to ensure the normal operation of cold water tower; can avoid the manual icing curtain removing operations, prevent the danger of personnel to slip in the pool. The pressure circulating return water of the self water-supply main pipe of the cooling tower is used to spray and antifreeze without any additional power, thereby saving a large number of de-icing steam.
Description
Technical field
The utility model belongs to circulation cooling cooling tower affiliated facility, is specifically related to a kind of device that is used to prevent the cooling tower freezed in winter.
Background technology
The hyperbola cooling tower is to be widely used in the critical facility that recirculated cooling water is provided to thermal power plant and large oxygen-making machine group etc., and cooling effect is better.Its operation principle is that the high temperature with the closed circulation cooling water system pushes back water, descend through cloth tank, shower nozzle and filler spray from the middle and lower part of cooling tower, directly contact by the unsaturated surrounding air that enters around the tower bottom with form big pressure reduction by structure, utilize the degree of unsaturation of surrounding air that recirculated water is cooled off.
Yet when northern China was used than cold district winter, because environment temperature is lower, the water of following of eaves can freeze at the bottom of the cooling tower, and time one length will form the ice curtain gradually.Serious time image skirt equally all blocks cooling tower bottom ventilating opening, causes air to enter, and makes cooling tower also lose cooling effect and effect.In order to keep its effect, have to adopt and manually beat the way that ice or steam-out (SO) thaw, not only increase task difficulty and labour intensity, and wasted energy, and had certain potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and aims to provide a kind of simple and practically, can effectively prevent the device of cooling tower freezed in winter.
For this reason, the concrete measure taked of the utility model is:
A kind of hyperbola cooling tower anti-icing equipment comprises looping back water pipe, and sets up upper hose and sparge pipe on the water pipe looping back, and the upper hose lower end loops back water pipe with cooling tower and is connected, and the upper end is connected with the sparge pipe that is provided with hole for water spraying.
After the utility model is implemented, thoroughly eliminate the icing phenomenon in cooling tower bottom, made dry Cryogenic air be continued to flow, guaranteed the normal operation of cooling tower.Avoid the operation of artificial deicing curtain, got rid of the danger that the operating personnel slips into the pond.Utilize cooling tower from water on one's body be responsible for to have the circulating backwater of pressure to spray antifreeze, need not add any power, thereby can save a large amount of deicing steam.And it is simple in structure, convenient and practical.
Description of drawings
Fig. 1 is a hyperbola cooling tower anti-icing equipment schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is hyperbola cooling tower anti-icing equipment installment state figure.
Among the figure: 1, hole for water spraying, 2, sparge pipe, 3, upper hose, 4, loop back water pipe, 5, cooling tower.
The specific embodiment
Below, in conjunction with the accompanying drawings the utility model is further described.
As seen from Figure 1, the utility model is by sparge pipe 2, upper hose 3 and loop back water pipe 4 and formed.The last water that loops back water pipe 4 and be cooling tower self is responsible for, and what be connected with higher temperature in the pipe has a pressure circulating backwater.Upper hose 3 just in time is connected on and loops back on the water pipe 4, high temperature is had push back water and send in the sparge pipe 2 that is connected on the upper hose 3, by opening the hole for water spraying 1 on sparge pipe 2, has pressure to spray to the cooling tower bottom by water high temperature again, freezes to prevent the bottom.
Can see significantly that from Fig. 2 the shape of cross section of the utility model sparge pipe 2 is 1/1st semi arch, circular arc design mainly is to consider structurally to press close to the cooling tower outer rim, install, convenient fixing firmly and the distance that can reduce and ice curtain.
Fig. 3 is hyperbola cooling tower anti-icing equipment installment state figure, can understand installation site of the present utility model intuitively.The utility model is satisfied with the side of the bracing frame that cooling tower 5 bottom air enter, and direction is the north side of cooling tower 5.
