Description
Technical Field
The invention relates to air purification equipment, in particular to a plant air purification system for treating benzene gas pollutants in air.
Background
With health concerns and longer indoor residence times, the composition and content of indoor pollutants has been valued. The benzene series gas pollutant molecules in the air contain hydrocarbon with benzene ring structure. Is one of the closed chain class. The compounds have the basic structure of benzene ring, and historically, the compounds found earlier have more aromatic flavor, so the hydrocarbons are called aromatic hydrocarbons, and later discovered hydrocarbons without aromatic flavor are also called aromatic hydrocarbon. Such as benzene, xylene, naphthalene, and the like. The general formula of the benzene homologue is CnH2n-6 (n.gtoreq.6). The number of pi electrons of the aromatic hydrocarbon is 4n +2(n is a non-negative integer). Benzene series compounds are widely available, such as automobile exhaust, organic solvents in building decoration materials, additives of paint, common adhesives in daily life, artificial board furniture and the like, which are pollution sources of the benzene series compounds. The composition and characteristics of benzene series from different sources are greatly different, and the discharge amount of the benzene series from different discharge sources is different.
The benzene series mainly comprises benzene, toluene, xylene and the like, and is commonly called as aromatic killer. The world health organization has identified benzene-based compounds as being strongly carcinogenic. For example, benzene was identified as a carcinogen by the World Health Organization (WHO) in 1993. The national standard 'civil building engineering indoor environmental pollution control code' (GB50325-2001) issued in 2001 stipulates that the benzene content in the indoor environment cannot be more than 0.9mg/m3. The indoor benzene content exceeds 2.4mg/m3(3.5ppm), people may have symptoms of chest distress, headache, nausea, vomiting, nerve paralysis and the like, and even death. The skin is frequently exposed to benzene-polluted environment, and the phenomenon of degreasing can occur, so that the skin is dry and desquamated. If a person stays in a low-concentration benzene polluted environment for a long time, the mental condition can be influenced to a certain extent, and symptoms such as memory deterioration, neurasthenia, insomnia and the like are caused. Benzene can also cause the reduction of leukocytes and platelets, which can lead to aplastic conditionsAnemia, and even more, can cause leukemia and cardiovascular disease.
Polycyclic Aromatic Hydrocarbons (PAHs) are produced in industrial production, fire coal, human activities, energy pollution and the like, and are pollutants which have great threat to human health and an ecological system, wherein some polycyclic aromatic hydrocarbons such as benzopyrene and the like have strong carcinogenicity and mutagenicity, and can be transmitted through a food chain to endanger the health of a human body due to harm caused by absorption and concentration of organisms.
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.

8. The plant air-purifying system for treating benzene-series gas pollutants in the air as claimed in claim 1, wherein the controller further controls the working current of the first light source part and/or the second light source part according to the benzene-series gas pollutant concentration in the indoor air detected by the benzene-series gas pollutant concentration sensor in the air.
9. The plant air-purifying system for treating benzene-series gas pollutants in the air as claimed in 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 type of the plant according to the image of the plant and controls the operating current of the first light source part and/or the second light source part according to the type of the plant.
10. A method for purifying air by the plant air purification system for benzene series gas pollutant treatment in air according to any one of claims 1 to 9, which comprises:
s1, detecting the concentration of benzene series 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 benzene gas pollutants in the air;
s3, adjusting the effective quantum flux density ratio of red light, blue light and green light through the working circuit and working current of the first light source part and/or the second light source part of the controller according to the detected concentration of the benzene series gas pollutants in the air;
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.
