Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cooling tower electrical separation devices, and in particular to a demisting device based on ion wind and chemical agglomeration. Background Art
[0002] The cooling tower is a comprehensive product that integrates aerodynamics, thermodynamics, fluid mechanics, chemistry, biochemistry, materials science, static and dynamic structural mechanics, processing technology and other disciplines.
[0003] As a water cooling technology, wet cooling towers are widely used in industries such as electricity and petrochemicals. During the operation of the cooling tower, the circulating water in the tower is in direct contact with the air for heat and mass transfer, which will cause evaporation loss, wind loss and sewage loss of the circulating water, resulting in a large waste of water resources. The evaporation loss of the cooling tower accounts for 30-55% of the total water consumption. Under certain climatic conditions, the evaporated water is cooled by the cold air outside to form white fog, which has an adverse effect on the urban landscape and road visibility. Therefore, it is of great significance to the cooling tower to reduce the evaporation loss by recycling the water in the fog. At present, the wet cooling tower mainly adopts three types of defogging technologies: heating type, multi-air volume type and air parallel type. The supersaturated wet air is adjusted to the unsaturated zone by heating or increasing the air volume, which only eliminates the "white fog" phenomenon, but the evaporation loss of the cooling tower is not reduced in terms of mechanism.
[0004] The prior art discloses a patent CN214487372U, which includes a support frame, on which a plurality of vertically arranged electrode plates are fixedly connected in parallel, and the electrode plates are also arranged vertically inclined, and a guide surface is formed through their inclined lower ends, and a liquid guide cavity shell arranged in the same shape as the guide surface is also fixedly connected to the support frame. This solution solves the problem that the condensed liquid droplets generated in the device of the traditional technology are prone to disorderly dripping during use, and cannot be guided out in an orderly manner, which affects the use environment of the demisting device.
[0005] As the device is used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:
[0006] First, during use, the existing defogger is integrated with the electrode wire and the electrode plate. Since it is used in a humid and harsh environment, a water layer is easily attached to the insulator between the electrode wire and the electrode plate, causing electrical connection between the electrode wire and the electrode plate, which directly affects the defogger effect.
[0007] Second, the existing electric field demisting method cannot collect fine particles of water droplets during the demisting process, making it impossible to collect this part of the water body, resulting in a waste of water resources.
[0008] Third, the existing demisting method also uses spraying to condense fine particles, but the spray range of the existing method is fixed, and the water mist moves upward at a high flow rate, reducing the contact time and area with the spray liquid, affecting the demisting efficiency.
[0009] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
