Problems solved by technology

The water pressure loss of the Venturi tube is generally 0.1-0.3MPa under the best working condition, the energy consumption per unit of gas volume is high, and the weight of the power equipment is also large
The Venturi tube itself is small in size, but generally requires a large installation and operation space
In addition, the processing and production of Venturi tube is relatively cumbersome

Abstract

The invention provides a vortex type air purifier, and specifically relates to an air purifier. With water vapor (with coexistence of gaseous water vapor and liquid mist, and collectively referred toas the water vapor) as a working medium, the air purifier captures air pollutants by utilizing the methods of gas-mist mixing and water vapor coagulation and condensation, and removes the air pollutants through a method of recovering the working medium by vortex separation.

Description

technical field [0001] A vortex-type air purifier, in particular, relates to a method that uses water vapor (the gaseous water vapor and liquid mist exist simultaneously, collectively referred to as water vapor) as the working medium, and utilizes the method of gas mist mixing, water vapor condensation and condensation An air purifier for removing air pollutants by capturing air pollutants and vortex separation and recovering working media. [0002] The air purification method based on the purifier refers to the method in which air pollutants are captured by the working medium, the method in which air pollutants are separated and recovered from the air along with the working medium, and the method in which the working medium is circulated and purified. Background technique [0003] In recent years, the air quality has deteriorated day by day, posing a threat to people's health. At present, the working methods and principles adopted by air purification devices mainly include...
