Indoor air firstly enters the air quality monitoring unit under the action of the air blower, the sensor inputs an analog signal of an air quality sensing result into the signal conversion unit, and the sensing result is finally displayed on the LCD display screen by utilizing the single chip microcomputer technology. The monitored air enters the air purification unit and sequentially passes through the activated carbon layer, the negative ion generation layer, the microorganism oxygen supply device and the activated carbon layer 2, and the purified air returns to the indoor environment through the air outlet.

Firstly, large particles, dust, smoke and other substances in the air are intercepted by the primary filter net, the primarily filtered air reaches the activated carbon layer 1, and under the action of the activated carbon, substances such as formaldehyde, xylene and other substances in the air and some peculiar smell are adsorbed. The negative ion generating layer can generate a great amount of negative ions and simultaneously generate a trace amount of ozone, and the combination of the negative ions and the ozone can cause the bacteria and the viruses in the air to generate structural change or energy transfer, so that the bacteria and the viruses die. In addition, negatively charged negative ions can also be electrode-neutralized with positively charged smoke dust floating in the air, causing its natural deposition.
The air passing through the anion generating layer enters the microorganism oxygen supply device through the pipeline, and the middle of the pipeline is provided with the check valve, so that the algae liquid can be prevented from entering other structures of the air purification unit in the circulating process.
In the microorganism oxygen supply device, air circularly flows in a circulating pipeline along with chlorella under the control of a silent water pump, carbon dioxide in the air is absorbed by the chlorella by utilizing the efficient photosynthesis of the chlorella, and meanwhile, oxygen is generated, and besides, hydrophilic PM2.5 can be absorbed by algae liquid, so that indoor air is purified.
Wherein, in order to guarantee the high growth efficiency of chlorella, the inside microorganism apparatus of oxygen supply of air purification unit adopts the design of circulating line formula, and the chlorella circulates in the photobioreactor pipeline and flows and can effectively prevent the chlorella because of adherence growth blocks the light source and reduce photosynthetic efficiency, makes it produce oxygen at the high-efficient while effectively reducing indoor high concentration carbon dioxide.
A temperature sensor, a pH sensor and a light intensity sensor are arranged in a photobioreactor of the microorganism oxygen supply device, the sensors are connected with a signal amplification circuit, and the index of the chlorella growth environment is displayed on an LCD screen by utilizing the singlechip technology; the bottom of the photobioreactor pipeline is provided with a light source, the top of the photobioreactor pipeline is provided with a heat source, the light source and the heat source are both connected with an amplifying output circuit, and an operator can control the on-off conditions of the light source and the heat source through a human-computer interface to enable chlorella to be in an environment suitable for growth.

The air after the treatment of microorganism oxygen supply device reaches activated carbon layer 2 through automatic air release valve, and the smell of algae liquid that the air carried through microorganism oxygen supply layer can be adsorbed to the activated carbon, and then, HEPA ultrafiltration layer will intercept hydrophobic PM2.5 that is not adsorbed by algae liquid. In the example, an H11 grade filter screen can be selected, the filtering rate of the filter screen on PM2.5 can reach 95%, and the filtering rate on other particulate matters can reach 100%. Finally, the purified air is discharged into the indoor environment through the air outlet.
Wherein, the primary filter screen, the activated carbon layer 1, the anion generation layer, the activated carbon layer 2 and the HEPA ultrafiltration layer are all in a drawing detachable design, so that the inspection and maintenance are convenient. Meanwhile, the negative ion generating layer is in a sealed design, so that the generated ozone can be prevented from leaking outside and harming human health.
Wherein, the middle part of the protective casing is of a transparent structure and can be made of PC material. The chlorella can fully utilize the illumination in the transparent structure, and meanwhile, the ornamental value is increased, and the operator can conveniently observe the growth condition of the chlorella.
Wherein, the design convenience of universal wheel that can stop is removed and is fixed an indoor air quality monitoring and clean system.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
