The embodiment of the utility model provides an in 1 clean system working process and principle:
haze air passes through booster fan 1 effect and gets into air supply main pipe 15 in, at first via aqueous medium clarifier 2, and it can detach the less particulate matter of diameter like PM2.5, can also improve the humidity of air, prepares so that improves its purification efficiency for subsequent various purification treatment. Then enters an ozone purifier 4 and a photocatalyst purifier 5, and bacteria, viruses and various microorganisms in the air are killed through the ozone purifier 4 and the photocatalyst purifier 5. Haze air enters the multilayer filter screen 10 after being sterilized, and the multilayer filter screen 10 adopts a three-layer filtering module of activated carbon, artificial fiber and activated carbon, so that most of particles in the haze air can be effectively removed. Then the air passes through a dust detector 11, if the quality of the air reaches the standard, the air is processed by a HEPA membrane through opening a main valve, and then the air enters the next link, if the quality of the air does not reach the standard, the air enters a return pipe 7 through a side valve 12, and then the air is processed in a multi-layer filter screen filter 10 again. The treated clean air is then delivered by a fresh air system to the various rooms, where the humidity of the air can be adjusted prior to delivery. In all programs, when the system does not need to stop working, the filter screen cleaning spray head 23 is started to start running, and dust deposited on the filter screen is removed by using water as a medium; then the medium water flows into a recycling system, and after treatment, clean water is conveyed into a main water pipe to be reused by the system.
Principle of the aqueous medium purifier 2: the effect of cooling can be achieved by spraying unsaturated air directly (or through a packing layer) by using circulating water, a wastewater collecting tank I21 is arranged below the water medium purifier 2, the circulating water is conveyed to the upper part of the packing layer through a water pump and is uniformly sprayed on the packing layer, and the water flows downwards by virtue of gravity and wets the packing; the air passes through the filler layer under the action of the fan and performs heat and moisture exchange with water, the air transfers the sensible heat to the water, the temperature is reduced, the water is evaporated to enter the air, and the moisture content and the latent heat of the air are increased. When the evaporative cooler normally operates, the air temperature can be effectively reduced, and the particulate matter removal efficiency is also effectively improved. The wetted filler material has an increased adhesion to the particulate material and a reduced ability to resuspend the particulate material. The filler will swell slightly after absorbing water. The slight expansion of the filler increases the contact area thereof, and the removal effect of the inertial collision and contact retention action is enhanced. The evaporative cooler mainly utilizes mechanisms of inertial collision, diffusion, contact retention and sedimentation to remove particulate matters in haze so as to purify air. When haze gas enters the aqueous medium purifier, a spray head 3 is arranged at the top of the aqueous medium purifier 2 to spray water to wet the filler; (wherein the spray head 3 takes the water in the water inlet pipe 26 as a water source) haze air (air components are residual PM2.5, residual dust and oxygen at this time) can remove most PM2.5 and residual dust by using mechanisms of inertial collision, diffusion, contact retention and sedimentation when passing through the wet filler layer, and the humidity of the air can be improved.
After water in the coating layer and sewage mixed with impurities permeate from the filler supporting plate 25, the water enters the wastewater collecting tank I21 below the device under the action of the inclined surface, part of the water is recycled and placed in the wastewater standing chamber 20 through a water pipe, the wastewater standing chamber 20 is connected with a water inlet pipe 26 of a spray head to realize cyclic utilization, and the rest of the water is discharged through a wastewater pipe of a water collecting tank.
Principle of the sterilization system: the haze air is firstly treated by the ozone purifier 4 and then purified by the photocatalyst purifier 5; regarding the ozone purifier 4, it is to generate a large amount of plasma through a high frequency discharger placed therein, high energy electrons collide with gas molecules to generate a physicochemical reaction, and activate the gas to generate various radicals and ozone; the haze air contains inhalable particulate matters (PM 2.5), bacterial pathogens, sulfur dioxide, nitrogen oxides and various tiny dusts, wherein the PM2.5 is taken as a main pollutant; after the haze air enters the ozone purifier 4, the organic gas can be instantly oxidized and degraded under low concentration through the strong oxidation effect of the ozone, so that pathogenic microorganisms can be killed. Therefore, the air purifier can purify toxic gases (such as formaldehyde, nitrogen sulfur oxides and the like), bacteria and viruses in the air. However, ozone is smelly, is unstable at normal temperature and pressure and is easily decomposed into oxygen; but still part of the undecomposed ozone will follow the rest of the gas into the next stage. The photocatalyst purification is to plate nanometer titanium dioxide as a photocatalyst on a common carrier filter screen. Under the action of external ultraviolet rays, light energy is converted into chemical energy. Due to the discontinuity of the semiconductor energy band, electrons and holes have a long lifetime, and they can move under the action of an electric field or by diffusion, undergo redox reactions with substances adsorbed on the surface of the semiconductor catalyst particles, or are trapped by surface lattice defects. It generates hydroxyl radicals, a highly reactive particle, which can oxidize and mineralize a variety of organic substances (harmful gases, viral proteins, etc.).
Principle of multi-layer screen filtration system: the multi-layer screen filter 10 employs a three-layer filter module of "activated carbon-rayon-activated carbon". The artificial fiber is synthetic fiber filter cotton for air filtration. When gas enters the multi-layer filter screen filter 10, the gas firstly passes through a primary filter screen with a three-layer structure of 'activated carbon-artificial fiber-activated carbon'; ozone in the gas and dust with larger particles can be adsorbed or deposited on the surface layer of the filter screen, and the ozone generated in the previous link can be effectively adsorbed; and then the gas passes through a high-efficiency filter screen, the residual organic matters are treated, the residual PM2.5 is deposited, and finally clean air is obtained. A high-pressure spray head is designed behind the filter screen; when the whole system stops running, the spray head sprays water from the direction opposite to the air flowing direction, so that dust (dust) deposited on the filter screen is sprayed out, and the filter screen is cleaned; as for the waste generated by cleaning, sewage formed by dust and water drops into the lower waste water collecting tank II 24 together, and then flows into the recycling system.
In the operation process of the total system, the water medium is used for cleaning the water medium purifier 2 and the filter screen, so that the used water is collected and settled in the wastewater standing chamber 20 through the wastewater collecting tank (the impurity density is higher and mainly deposits at the bottom, so that the water quality of the upper layer is better), and then the impurity water at the bottom layer is discharged through the wastewater discharge pipe 19; the clear and clean water at the upper layer is conveyed to the water inlet pipe 26 through the circulating water recovery pipe 6 by using the water pump 17 as power to complete a water cycle for further use.
Dust accumulation detection system principle: when the air passes through the dust deposition detector 11, the quality condition of the air at the moment can be detected; if the quality of the air reaches the standard, opening the air by the main valve and entering a humidity regulation link; if the air quality does not reach the standard, the air enters another pipeline through a side valve, and enters a humidity adjusting link after being processed by an HEPA film; the treated clean air is then delivered to each room by a fresh air system.
