detailed description

The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments. It is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

Referring to FIG. 1, FIG. 1 is a schematic flow chart of a first embodiment of a method for removing dust mites according to the present invention. The steps of the method include:

S101: evacuating the air inside the absorption device to form a low pressure region.

Haze has become the main pollution route in the northern autumn and winter festivals in China, and has begun to spread southward. It is particles, dust, aerosols and other particles with a diameter less than or equal to 2.5 microns in the floating atmosphere, under certain weather conditions such as humidity and temperature. The weather phenomenon produced in a relatively stable state has become a "killer" for human health.

In the early morning of the warm season, people often see dew on the grass, leaves and crops on the roadside. The formation of the dew is due to the fact that when the ground object is strongly radiated and cooled at night, the temperature of the air in contact with the surface of the object drops, and after it falls to the "dew point", excess water vapor is deposited. This excess water vapor condenses into water droplets attached to the ground object, which is the dew. At the same time, objects that are prone to dew formation are often objects with relatively large surface areas, rough surfaces, and poor thermal conductivity. The dust particles in the smog can be used as condensation nuclei to condense the water vapor in the air, and finally the two combine to achieve the purpose of purifying the air.

In the method of the present invention, the air inside the absorbing device is evacuated by means of an exhaust fan, at which time a low pressure region is formed inside the absorbing device, and the extractor needs to be operated in real time so that the inside of the absorbing device is always at a low pressure. Then, the process proceeds to step S102.

S102: The dust-containing air enters the inlet of the absorption device, and passes through an absorption plate disposed in the absorption device, and the water vapor in the dust-containing air is cooled and liquefied by the absorption plate to form droplets.

The absorbing plate has the structure shown in Fig. 2 and is composed of a main board and a cooling duct. The main board has a rough surface and has a low temperature. The overall setting is wave-shaped. The cooling duct is placed under the wave type main board and is curved and closely tangential to the wave-shaped crest of the main board, so that the cooling effect of the coolant in the cooling duct acts on the main board, through the first duct and the coolant. A memory connection to provide coolant within the cooling duct. Since the outside air pressure is higher than the air pressure inside the absorbing device, the dust-containing air from the outside of the absorbing device enters the inside of the absorbing device and contacts the absorbing plate provided inside the absorbing device. According to the foregoing formation principle of the dew, the main board is equivalent to the surface of the object described above, and the temperature of the air in contact therewith is lowered, and the water vapor therein condenses into droplets when it is near the absorption plate. After the water vapor is liquefied, the process proceeds to step S103.

S103: The droplets agglomerate the dust particles in the dust-containing air and adhere to the surface of the absorption plate, and the air from which the dust particles are removed is discharged from the outlet of the absorption device.

The water vapor in the air condenses into droplets after encountering the lower temperature absorption plate. As described above, the water has the function of absorbing, bonding, and fixing the "fine particles", and the dust particles can be used as a good condensation tube. The droplets combine to eventually land on the surface of the absorbent sheet.

In the present invention, the absorbing plate has a wave shape, and the overall outline is a rectangle or a square, and two of the four sides are straight lines, and two of them are wavy lines. When the absorbing plate is provided to be connected to the inner wall of the absorbing device, the side of any wavy line is connected to the absorbing means. When the interior of the absorbent device is circular or otherwise irregular, the end of the absorbent plate to which it is attached should conform to the arc inside the absorbent device. When the dust particles and droplets fall on the absorbent plate, they slide down the surface of the collection box under the absorption device. Dust particles in the air entering the absorption device are absorbed, and the remaining air containing no dust particles is discharged from the outlet of the absorption device.

Further, a plurality of absorbing plates arranged in series are disposed inside the absorbing device, and the absorbing plates are placed in parallel or irregularly placed, and can be inclined horizontally, upwardly, or downwardly. One end of the absorption plate is connected to the absorption device, and the other end is suspended. The air containing fine dust particles entering the inside of the absorption device can be treated multiple times to absorb as much fine dust particles as possible to obtain cleaner air. At the same time, holes may be provided in the surface of each of the absorbing plates, and the smaller the diameter of the holes, the better, preferably smaller than the diameter of the fine dust particles. Such an absorption plate will block the dust particles in the air and facilitate the purification of the air.

Further, the first pipe connecting the external coolant storage tank and the cooling pipe is set as a negative corona wire, and a high-voltage electrostatic field is formed between the energized and the 0-potential absorption plate. After entering the electric field, the air containing dust mites is electrically separated, and the dust particles in the air are combined with the negative ions to carry a negative charge, and move together to the zero potential absorption plate in the high voltage electrostatic field, and finally stay on the absorption plate, and the air. Separation occurs and the air is purified.

Different from the prior art, the dust removing method of the present invention liquefies the water vapor in the dust-containing air by the cooling action of the absorbing plate, and the liquefied liquid condenses the dust particles in the air to remove the air of the dust particles. Excluding the outlet, it can play a role in purifying the air, and it is easy to operate and has a high safety factor.

In the present embodiment, before the apparatus 200 is used, the air inside the apparatus 200 is evacuated using an air suction means (not shown) to form a low pressure region therein. Air is then blown into the interior of the device 200 from the air inlet 2011 using a blowing device (not shown), at which time the air entering the device 200 is smog-containing air. After the air enters, it comes into contact with the absorbing plate 201, and the water vapor in the air condenses into droplets, and the PM2.5 particles in the air act as condensed tubelets which are excellent in effect and are absorbed by the droplets. The droplets are attached to the surface of the main plate 2021 of the absorption plate 202. Since the main plate 2021 is inclined downward, the liquid droplets fall on the main plate 2021 and fall along the slope of the main plate 2021 to the lower liquid droplet collection box 203. The PM2.5 particles in the air are absorbed by the droplets and are discharged from the air outlets 2012 below the outer casing 201. At the same time, an air blower may be disposed in the vicinity of the device 200 to accelerate the flow of air near the air inlet 2011 to facilitate air entering the device 200. Process it.

The number of undulating troughs on the 302 is equal. When the absorbing plates 302 are arranged opposite each other, each of the second passages 3013 passes through the absorbing plate 302, and an opening is provided at a position on each of the second passages 3013 in contact with the absorbing plate 302. The droplets incorporating the PM2.5 particles can be passed from the opening into the second conduit 3013 and finally to the droplet collection tank 303.

Similarly, the air in the apparatus 300 is first evacuated using an air exhausting device (not shown) to form a low pressure region inside the outer casing 301.

Further, a hole (not shown) is provided on the surface of the absorbing plate 302, and its diameter should be smaller than the diameter of the PM2.5 particles. When the outside air enters the device 300 and encounters the absorbing plate 302, the PM2.5 particles are blocked by the absorbing plate 302. After the water vapor in the air condenses into droplets, the combination is sucked The PM2.5 particles blocked by the plate 302 are closed.

Compared with the prior art, the device for removing dust mites of the present invention allows outside air to enter from below the device, and the PM2.5 particles are combined by droplets liquefied by water vapor, attached to the surface of the absorbing plate, and reach the inner wall of the device casing along the surface thereof.
