Air purifier with PM2.5 (particulate matter 2.5) removing function on basis of micro-algae

Abstract

The invention discloses an indoor air purifier which comprises a liquid storage tank, filter elements, activated carbon, an exhaust fan and ultraviolet lamp devices. The indoor air purifier has the advantages that air can be upwardly exhausted from the lowermost layer by the exhaust fan, a spray nozzle is arranged above each layer of filter elements, alga liquid sprayed by the spray nozzles can be sufficiently in contact with the air, particulate matters and water-soluble matters in the air can be dissolved in water, accordingly, a PM2.5 (particulate matter 2.5) value of the air can be greatly lowered, and the air further can be humidified; NOx, formaldehyde, heavy metal ions and the like in the air can be absorbed and utilized by micro-algae after being dissolved in the water and subjected to reaction by the aid of culture media; pollutants in the air can be absorbed by the micro-algae and can be converted into nutrition of the micro-algae, and oxygen can be released by the aid of photosynthesis; VOCs (volatile organic chemicals) in the air can be adsorbed and removed by the activated carbon of activated carbon layers; inactivation effects can be realized for bacteria in the air by ultraviolet lamps; four air purification technologies including a micro-alga purification technology, an activated carbon adsorption technology, a water washing purification technology and an ultraviolet sterilization technology are combined with one another, and accordingly service requirements of modern families can be met.

Description

technical field [0001] The invention relates to an air purifier for removing PM2.5 based on microalgae, belonging to the field of gas purifiers. Background technique [0002] In recent years, large-scale smog has occurred frequently across the country, and PM2.5 has exploded in many places. Atmospheric environmental pollution has become a major problem that threatens human survival. Modern people spend more than 80% to 90% of their time indoors. Pollutants in indoor air have a great impact on human health. Therefore, controlling and treating indoor air pollution is an effective way to improve the living environment of human beings. [0003] For most people living in modern cities, about 60% to 70% of their time is spent indoors, and the quality of living conditions is closely related to their health. Indoor pollutant concentration is 2 to 5 times higher than outdoor, [0004] In special cases it can reach 100 times. Indoor pollution has the characteristics of large range ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the gas from the photocatalyst device is sent into the algae liquid of the microalgae cultivator through the air distributor, and then undergoes photosynthesis treatment through the algae liquid. The device is complex and the components are cumbersome, which affects marketization. commercial application
