Description
Technical Field
The invention relates to air purification equipment, in particular to a plant air purification system for treating gas pollutants in air.
Background
With health concerns and longer indoor residence times, the composition and content of indoor pollutants has been valued. Among indoor polluted gases, gaseous pollutants in the air are also widely present as formaldehyde, benzene series and the like. Gaseous pollutants in air, including various compounds, such as ammonia gas and nitrous oxide (N)2O), Nitric Oxide (NO), nitrogen dioxide (NO)2) Dinitrogen trioxide (N)2O3) Dinitrogen tetroxide (N)2O4) And dinitrogen pentoxide (N)2O5) And the like. Besides nitrogen dioxide, other air pollutants are extremely unstable and change into nitrogen dioxide and nitric oxide when exposed to light, moisture or heat, and the nitric oxide changes into nitrogen dioxide. Thus, the occupational environment is exposed to several gas mixtures, commonly known as niter fumes (gases), mainly nitrogen monoxide and nitrogen dioxide, and mainly nitrogen dioxide. Gaseous pollutants in the air all have varying degrees of toxicity.
When removing indoor pollutants, generally speaking, the problem of indoor pollution is solved by purchasing an air purifier or planting green plants indoors. However, when the air purifier is used, the filter element equipment needs to be replaced regularly, the purifying effect is not ideal, a large amount of noise is generated, and the rest of a user is influenced.
For planting plants indoors, a user can select corresponding plants by looking up a large amount of data in consideration of the fact that one plant only has a good purification effect on one pollutant or a plurality of pollutants; in addition, in the process of planting plants, some plants can be withered due to ineffective illumination, and the air purification effect is poor.
The illumination intensity of the indoor environment is obviously different from that of natural illumination, if the indoor arrangement of the plants meets the required illumination characteristics, the photosynthesis of the plants is strong, the plants grow strongly, the leaves are emerald green, the stems are tall and straight, and the leaves are thick and solid; if the indoor illumination is lower than the illumination intensity required by the plant, the stems and leaves of the plant grow thinly and lusterless, and the phenomenon of spindly growth occurs, and the leaf color of the leaf-viewing plant (such as Pueraria lobata Ohwi and leaf-changing wood) with the speckles can become light, yellow and fuzzy, thereby not only affecting the viewing effect of the plant, but also affecting the viewing life and normal growth and development of the plant. The illumination intensity range in the room is 50-5218 lux. Data show that it is generally believed that illumination levels below 300Lx will cause plant growth to be debilitating and unable to sustain growth. Especially in the month of february, the indoor light intensity is low and cannot meet the minimum requirement of most plants. The light intensity near the south window or on the balcony is higher, and the position 80cm away from the window and 100cm high is the area with stronger scattered light in the suffocation according to the related data. Along with the extension to indoor, illumination intensity reduces gradually, can not satisfy the requirement of plant to light. In this case, the photosynthesis of the plant is greatly reduced, the activity of the degrading enzyme is greatly affected, and the pollutant-degrading ability is weak.

9. The plant air-purifying system for controlling airborne pollutants according to claim 1, further comprising an image acquisition device for acquiring an image of a plant and transmitting the image of the plant to the controller, wherein the controller analyzes the kind of the plant based on the image of the plant and controls the operating current of the first light source unit and/or the second light source unit based on the kind of the plant.
10. A method of purifying air by a phytosanitary air system for the remediation of gaseous pollutants in the air as claimed in any one of claims 1 to 9, comprising:
s1, detecting the concentration of the gas pollutants in the indoor air;
s2, configuring the plant type and number in the plant air purification system according to the detected concentration of the gas pollutants in the air;
s3, according to the detected concentration of the gas pollutants in the air, the effective light flux density proportion of red light, blue light and green light is adjusted through the working circuit and the working current of the first light source part and/or the second light source part of the controller;
s4, regulating and controlling the degradation capability of the enzyme system in the plant body through the effective quantum flux density ratio of the red light, the blue light and the green light.
