Description

Technical Field

[0001] The utility model relates to the technical field of industrial circulating water energy conservation and water saving, and is a windmill type circulating water saving and fog eliminating device. Background Art

[0002] The industrial circulating water device is an important part of chemical production and plays an important role in the dynamic heat balance of the system. In the industrial circulating water device, the cooling tower uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the water temperature; it relies on the heat exchange between water and air flow contact to generate steam, and uses the principles of evaporation heat dissipation, convective heat transfer, and radiative heat transfer when the steam volatilizes to dissipate the waste heat generated in industrial production or refrigeration and air conditioning to reduce the water temperature, so as to ensure the normal operation of the system.

[0003] During the operation of the cooling tower in the industrial circulating water device, the generated water mist is a normal physical change after the contact of cold and hot air. The main reason is that the cold air extracted by the fan becomes warm and humid saturated air after passing through the inside of the cooling tower and heat exchange with water, and when it meets the external cold air, water vapor quickly condenses to generate it.

[0004] Especially in high altitude or cold winter regions, "water mist" forms in winter and causes a self - snowing phenomenon, which affects industrial plant operations, the working environment, road traffic safety, and equipment corrosion in the plant device area. Not only does it require personnel to clear snow and prevent freezing in a timely manner, but also when operating, the water vapor velocity at the outlet of the circulating water fan reaches 4.3 m / s, carrying a large amount of water vapor to escape, resulting in a great waste of water resources. Summary of the Invention

[0005] The utility model provides a windmill type circulating water saving and fog eliminating device, which overcomes the above - mentioned deficiencies of the prior art and can effectively solve the problems of large water mist and easy freezing in winter existing in the existing industrial circulating water device.

[0006] The technical solution of the utility model is realized by the following measures: a windmill type circulating water saving and fog eliminating device, including a suction pool, a packing layer, a cooling tower, a circulating water fan, a rotating windmill, and a metal mesh. The packing layer is fixedly installed above the suction pool, the cooling tower is arranged above the packing layer, the circulating water fan is arranged above the cooling tower, the rotating windmill is installed on the top of the circulating water fan, the metal mesh is laid below the circulating water fan, the bottom outlet of the suction pool is fixedly communicated with a circulating pipeline, a spraying ring is arranged on the circulating pipeline between the packing layer and the metal mesh, the upper inlet of the cooling tower is fixedly communicated with a circulating water up - tower pipeline, and a circulating water down - tower pipeline is fixedly communicated between the circulating water up - tower pipeline and the bottom inlet of the suction pool.

[0007] The following is the further optimization or / and improvement of the above - mentioned technical solution of the utility model:

[0008] The above-mentioned circulating pipeline enters the cooling tower from the upper part of the cooling tower. A circulating pump is fixedly installed on the circulating pipeline. A circulating pump inlet valve is fixedly arranged on the circulating pipeline between the suction pool and the circulating pump. A circulating pump outlet valve is fixedly arranged on the circulating pipeline between the circulating pump and the cooling tower.

[0009] A lower tower control valve is fixedly arranged on the above-mentioned circulating water lower tower pipeline. An upper tower control valve is fixedly arranged on the circulating water upper tower pipeline.

[0010] The above-mentioned rotating windmill includes rotating windmill blades, a rotating windmill rotating shaft, and a sliding track. The rotating windmill blades are fixedly connected through the rotating windmill rotating shaft at the central position. A sliding track is installed at the bottom of each group of rotating windmills.

[0011] The above-mentioned rotating windmill blades are composed of back-to-back blades arranged in a staggered manner on the upper and lower sides. The back-to-back blades arranged in a staggered manner on both sides are fixedly connected through connecting pieces. The back-to-back blades are provided with blade openings with the orifice turned outwards.

[0012] The above-mentioned upper inlet of the cooling tower is located between the packing layer and the circulating pipeline in the cooling tower.

[0013] The structure of the utility model is reasonable and compact, and it is convenient to use. It uses a circulating device to distribute and spray part of the water in the suction pool above the packing layer, and makes reverse contact absorption with the rising water mist of the circulating return water to reduce the content of the rising water mist. The rising water mist in the circulating return water first contacts the metal surface, and part of the water mist is intercepted and condensed. The residual velocity of the water vapor at the outlet of the circulating water fan drives the rotation of the rotating windmill. After the rising water mist makes large-area contact with the rotating windmill blades, it is thrown off and drops, and finally falls into the suction pool, having the characteristics of safety, labor saving, simplicity, and high efficiency.
