specific Embodiment approach 1
[0026] Specific Embodiment 1: This embodiment provides an ecological indoor air purification device, such as figure 1 and 2 As shown, the ecological indoor air purification device adopts an integrated design, which is composed of four parts: air ventilation pump 1, air distribution system 2, air washing and purification unit 3 and air wetland ecological purification unit 4, to realize ecological indoor air purification.
[0027] The air ventilation pump 1 draws indoor polluted air into the air distribution system 2 located at the bottom of the air washing and purification unit 3, and the air distribution system 2 distributes the air in the form of micro-nano small bubbles through the perforated air distribution pipe 2-1. Distributed at the bottom of the air washing purification unit 3.
[0028] The air washing and purification unit 3 is a rectangular pool body 3-1 located at the bottom of the air purification device. The pool body is equipped with tap water 3-2, the upper par...
specific Embodiment approach 2
[0030] Specific implementation mode two: This implementation mode provides an ecological indoor air purification method, and the specific implementation steps are as follows:
[0031] 1. The air is sucked by the air exchange pump into the air distribution system connected to it at the bottom of the air washing and purification unit.
[0032] 2. In the air washing and purification unit, the air is dispersed into micro-nano bubbles by the air distribution system. The bubbles have a smaller volume and a larger relative area, making it easier for particles, metal ions, inorganic substances and some organic substances in the gas to It is wrapped by water molecules and forms polar adsorption, dissolves in the water body, and is washed and removed by water; at the same time, the residual chlorine in tap water can effectively kill bacteria and viruses, and realize the preliminary purification of the air.
[0033] 3. The initially purified air bubbles rise into the air wetland purifica...

Abstract
The invention discloses an ecological indoor air purifying device and method. The ecological indoor air purifying device comprises a main body, wherein a pool body serves as the main body and comprises the following four parts: an air scavenging pump, an air distribution system, a water-scrubbing air purification unit and a wetland-ecosystem air purification unit; the air distribution system is positioned at the bottom of the water-scrubbing air purification unit and connected with the air scavenging pump; the water-scrubbing air purification unit is filled with tap water; a bottom stainless steel orifice-plate bearing plate, a wetland quartz sand substrate layer, a wetland carbon fiber woven substrate layer, a wetland diatomite substrate layer and wetland plants are sequentially arranged in the wetland-ecosystem air purification unit from bottom to top; the bottom stainless steel orifice-plate bearing plate is positioned at the top of the water-scrubbing air purification unit; and the root systems of the wetland plants are positioned in the wetland quartz sand substrate layer. The ecological indoor air purifying device disclosed by the invention is simple in structure, flexible to construct and convenient to maintain, and can be adopted in both the southern and northern areas; the ecological purification of indoor air can be achieved; the construction cost is low; the running cost is low; the long-term effect is good; and the landscape effect is good.
Description
technical field [0001] The invention belongs to the technical field of indoor air purification, and relates to an indoor air purification device and method. Background technique [0002] Modern people spend 80% or even 90% of their time indoors. Indoor air quality is closely related to health, but there are many types of indoor pollution sources: excrement of human life itself, environmental release of indoor furniture and decoration, kitchen cooking process The release of pollutants in the air leads to indoor air pollution; especially in winter in the north, the outdoor environment is seriously polluted, and there is no condition for opening windows for ventilation, which aggravates indoor air pollution. Therefore, developing an efficient and ecological indoor air purification method to provide a healthy living environment for life activities is a requirement for life protection. [0003] Known indoor air purification methods are of a great variety: the physical adsorption...
