Water suction-drainage fan

Abstract

The invention discloses a water suction-drainage fan which comprises an air barrel and a fan arranged in the air barrel; and fan blades of the fan are made of a water absorption material. In use, when water vapor is exhausted into the air barrel, fan in the air barrel absorbs water vapor as a result of the adopted water absorption material; water vapor absorbed by fan blades of the fan is thrown onto the inner wall of the air barrel when the fan rotates at full speed; under action of gravity, water flows down along the inner wall of the air barrel, enters a water storage tank through a ring-shaped water collecting slot formed in the air barrel, and is exhausted from a water outlet tube, and flowed-out water can be continuously utilized after being treated by a sewage treatment device subsequently. The water suction-drainage fan disclosed by the invention can effectively reduce white smoke (water vapor) exhausted from the top of a chimney, effectively avoids the shut-down problem caused by report of uninformed ones, so that working efficiency is improved; and meanwhile, water vapor exhausted from the chimney can be treated and recycled, so that resources are saved and waste is reduced.

Description

technical field [0001] The present invention relates to the field of fan technology, and more specifically, to a suction and discharge fan. Background technique [0002] At present, in places with chimneys such as steel mills, thermal power plants, and chemical plants, it is often seen that white smoke is discharged from the chimney. In fact, these white smoke is water vapor, mainly white mist formed after water vapor condenses. In recent years, the country has been very strict on smoke and dust control. The dust removal devices of power plants, chemical plants, steel mills and other enterprises have been greatly improved. The application of electrostatic dust removal and bag dust removal has made the dust removal rate reach more than 99%. All chimneys There is basically no smoke and dust, and the white one can be said to be water vapor, which is the water vapor generated by the high temperature after the desulfurization device sprays water to the flue. [0003] In the actu...

Problems solved by technology

[0003] In the actual production process, many people do not understand this situation and mistakenly think that the white smoke is the polluting gas discharged by enterprises or factories. Some uninformed people often report to the relevant departments. At this time, enterprises or factories will face shutdown. The situation of the investigation, causing economic losses to the enterprise or factory

Therefore, it is necessary to reduce the emission of these white flue gases. The existing technology only removes the pollutants in these white flue gases and then discharges them without further treatment of water vapor.
