Vertical indoor formaldehyde hydroponic plant ecological purification system

Abstract

The invention discloses a vertical indoor formaldehyde hydroponic plant ecological purification system, belongs to the technical field of air purification plants. The system is composed of a verticalsupport loading structure, a plant planting trough, a water circulation system, a purified water tank, purified plants and the like; the system is reasonable in structure, ensures stretching space forpurifying plant leaves and the separation growth of roots, improves the purification rate and resistance of formaldehyde of plant needles, adjusts indoor environment temperature and humidity, has high ornamental value, and has the advantages of good formaldehyde reduction effects, low energy consumption, low investment, no pollution, green, environmental protection, strong sustainability and thelike.

Description

technical field [0001] The invention relates to a purification system for improving indoor air quality, in particular to a hydroponic plant ecological purification system for purifying indoor formaldehyde, and belongs to the technical field of air purification plants. Background technique [0002] Indoor air pollution is a serious problem that threatens the health of urban residents for a long time. Among many organic pollutants, formaldehyde has become one of the ubiquitous and most serious indoor pollutants in the world due to its wide range of sources, great harm, and long duration. The main sources of pollution are indoor inferior wood-based panels, decorative materials, indoor furniture, tobacco burning and a small amount of cosmetics, detergents, insecticides, printing inks, etc. The national standard of the People's Republic of China "Hygienic Standards for Formaldehyde in Indoor Air" stipulates that the maximum allowable concentration of formaldehyde in indoor air i...

Problems solved by technology

[0004] At present, there are still technical problems in plant purification technology. For example, Chinese patent CN 104474882A discloses a method for ecological purification of indoor air plants. It only discloses plants that absorb pollutants such as formaldehyde, carbon monoxide, carbon dioxide and sulfur dioxide in the air. In the macro research of purification technology in the field of purifying indoor air pollutant types, no special plant combination has been proposed for the purification of formaldehyde in the air from a micro perspective

The inventor manufactured the same artificial pollution degree according to the technical scheme in the patent, selected the same plants for experimental research and found that the 100% purification rate described in the patent could not be reached, and on the second day, the planted plant Chlorophytum The leaves of asparagus and asparagus have very obvious spots and wilting, and the growth condition of the plants is very poor, close to death. This kind of scheme will cause great damage to the combined plants and is not conducive to the sustainable growth of the plants.

[0005] At the same time, most of the plant combinations in the prior art are simple arrangement and combination of different plants on the plane, which not only cannot maximize the purification effect and unique ornamental value of the plants, but also has the constraint of occupying too much indoor limited plane space.
