Description
Technical Field
The invention belongs to the field of air purification, and particularly relates to multi-air-energy air purification equipment.
Background
Air pollution can be broadly classified into two categories: the particulate matter exceeds the standard and the volatile organic compounds exceed the standard. The particulate matter mainly comprises various dust particles brought from the outdoor, PM2.5, allergic pollen, bacteria, viruses, dander cutin, pet droppings and the like; if the particulate matters are excessively inhaled and deposited in the body, diseases of the respiratory system can be caused, and the risk of lung cancer and heart disease can be increased; bacteria and viruses are easily allergic and ill to human skin. Volatile organic substances are indoor pollution, such as formaldehyde, benzene, nitrogen dioxide and the like, and the existence of the volatile organic substances is easy to cause diseases of the body, and the diseases are healthy body diseases.
From the working principle of the air purifier, the following two main categories are divided: passive adsorption filtration and active air purification. Passive adsorption filtration formula air purification utilizes the fan with in the air suction machine, carries out filtered air through built-in filter core, mainly can play the effect such as the great dust of filtration, peculiar smell, disinfection. The filter element type air purifier mainly adopts methods such as an HEPA filter element, an active carbon filter element, a photocatalyst (a cold catalyst, a multi-remote catalyst), an ultraviolet sterilization disinfection and an electrostatic adsorption filter element to treat air, wherein the HEPA filter element has the function of filtering dust particles, other active carbon and the like mainly have the function of adsorbing peculiar smell, but passive air purification needs great later-stage maintenance, and pollutants with the size below 0.3 mu m cannot be removed; the active air purification principle is fundamentally different from the passive air purification principle in that the active air purifier gets rid of the limitation of a fan and a filter screen, does not passively wait for indoor air to be pumped into the purifier for filtering and purifying and then discharged through the fan, but effectively and actively release purification and sterilization factors into the air, and reach all corners of the room to purify the air without dead angles through the characteristic of air diffusibility, the active purification technology which is mature in technology mainly utilizes negative oxygen ions as purification factors to treat air, low voltage is increased to direct current negative high voltage through a pulse type circuit and an oscillating electric appliance, the direct current negative high voltage is connected to a release tip, and a large amount of electrons (e-) are released at high speed by utilizing the direct current high voltage of the tip, and the electrons cannot exist in the air for a long time and can be immediately treated by oxygen molecules (O) in the air.2) Trapping to generate negative air ions, and generating active oxygen and oxygenStrong disease resistance, air freshening, smoke prevention and dust control, and has more obvious purification effect on smaller harmful particles, but has relatively common purification effect on larger particles such as hair, dust and the like.
Analytical comparison of the two types of air purifiers: 1) from the aspect of air purification efficiency, passive air purification mostly can only produce certain purification effect around the air purifier is placed, can filter indoor air once for a long time, hardly produces the effect to the purification of whole indoor environment. The active air purification is to utilize the characteristic of the diffusibility of air to enable purification factors to reach all corners for air purification, and the places where the air can permeate can generate purification effect; 2) the negative ion air purifier for air purification based on the active purification principle finds that the negative ions with small and medium particle sizes in the air can not only easily remove the particles with large particle sizes in the air, but also has a settling removal effect for the particle floating dust with the diameter smaller than 0.01mm and difficult to remove industrially; 3) the passive air purification speed is high, the active air purification speed is low, pollutants can be adsorbed and fixed to the filter screen to be subjected to centralized treatment in the passive mode, and the pollutant particles agglomerated in the active air purification mode are prone to drifting in the air after being settled. Whole contrast, the passive form air purifier of taking the fan can be faster purify great granule, and active air purifier can be quieter last clean air, and active air purifier purifies more obviously to less harmful particle, nevertheless is general relatively to the purifying effect of great granule such as hair, dust, adopts initiative and all has its advantage passively to volatile organic compounds.
The existing purification products generally have the following problems: mainly aiming at PM2.5 small particles, organic matters such as formaldehyde, VOCs and the like cannot be removed or the removal effect is not obvious; there are few products on the market that combine active and passive purification, and the removal of contaminants present in small quantities is poor.

Furthermore, through the design of switching the working modes, the use frequency of the thermal catalytic combustion catalyst is reduced, the use frequency of high-temperature desorption of the adsorption layer 3 is reduced, the service lives of the adsorbent and the thermal catalyst are prolonged, the maintenance period of the purifier is shortened, and the service life of the purifier is prolonged. In addition, by switching the two working modes, the adsorption layer 3 is guaranteed to accumulate the adsorption concentration of organic matters to a certain degree, and then the high-temperature desorption is more beneficial to thermal catalytic combustion, so that the high-temperature desorption catalytic combustion effect is guaranteed.
The first air inlet, the second air inlet, the exhaust port 18, the second ventilation hole and the third ventilation hole are all provided with valves 11. The above arrangement enables the flow rate of the gas to be controlled. The valve 11 can be a butterfly valve which can flexibly control the gas flow. According to PM2.5, formaldehyde and VOCs concentration detected by the gas detector, the temperature sensor 9 detects that the temperature of the exhaust port 18 is too high, the size of the valve 11 is adjusted, and the gas flow is controlled. When the temperature detected by the temperature sensor 9 is too high, the size of the valve 11 is adjusted, and the gas flow of the second air inlet and the first air vent is adjusted to be small; when the gas sensor 10 detects that the concentrations of the PM2.5, formaldehyde and VOCs in the exhaust port 18 are too high, the size of the valve 11 is adjusted, and the gas flow of the second air inlet and the first air vent is reduced.
In conclusion, the above embodiments are merely intended to illustrate the technical solution of the present invention and not to limit, although the present invention has been described by referring to certain preferred embodiments thereof, it should be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
