Embodiment Construction

[0020] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0021] The invention is a water-washing air purification method. Firstly, an electrolytic ozone generator is used to prepare ozone, and the prepared ozone is mixed with clean water in a Venturi high-efficiency mixer, and air and water can be efficiently mixed in this mixer. Its mixing efficiency can reach more than 60%; then, the dirty air and ozone water to be purified are input into the supergravity device, and the centrifugal force field is formed through the rotation of the supergravity device, so as to realize the supergravity state in the equipment; under the condition of supergravity , the multiphase flow system has a unique flow behavior, which can strengthen the relati...

Abstract

The invention discloses a washing type air purification method which comprises the following steps: A, preparing ozone water, B, mixing contaminated air and the ozone water to form a gas-water mixture to enable the ozone water to purify the contaminated air, C, separating the gas-water mixture to obtain fresh air and pollutant-containing wastewater, D, leading the pollutant-containing wastewater into a sewage treatment system for treatment, and removing pollutants to obtain clean water, and E, recycling the clean water to prepare the ozone water. According to the washing type air purification method disclosed by the invention, a direct air treatment method for air purification in the prior art is converted into a water treatment method, so that various pollutants in the air can be completely and efficiently absorbed and decomposed, and any secondary pollution can be avoided; the wastewater with the pollutants can be recycled after being treated by the sewage treatment system; therefore, the washing type air purification method is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water washing type air purification method. Background technique [0002] At present, the purification technology to solve air pollution is mainly filtration and decomposition. Among them, the filtration technology adopts filter elements or filter screens, which can effectively purify suspended solids in the air, but for micro particles (such as PM2.5) and bacteria, viruses, There is nothing you can do about odors and volatile organic compounds, and during the filtration and adsorption process, as the suspended solids absorbed by the filter element or filter screen increase, its filtering function will gradually weaken until it disappears, and it is necessary to clean or replace the filter element or filter screen regularly; The decomposition technology generally uses ultraviolet light, plasma, ozone and other oxidative decomposition methods to decompose organi...
