An Improved Smoke-and-Dust Air Treatment Unit (Utility Model CN 208493568 U)

Abstract link

The present utility model relates to the technical field of air purification treatment, and in particular to an improved smoke-and-dust air treatment unit. The box body is partitioned into a first filtering space, a second filtering space, and a third filtering space; the first filtering space filters some dust of relatively large volume. Under the condition that an induced draft fan promotes air flow, the air, after the relatively large dust has been filtered out, passes through multiple filter plate layers and enters the second filtering space; the second filtering space mainly filters bacteria in the air by irradiation of sunlight; the air after completion of filtration enters the third filtering space for ultraviolet filtration, and the filtered air is then discharged from an air outlet under the action of an exhaust fan. Through the three-layer filtration structure, a good smoke-and-dust air filtration effect is thereby achieved.

[0002] Smoke-and-dust pollution refers to the degradation of air quality caused by particulate pollutants in the air. The impacts and hazards caused by smoke-and-dust pollution are multifaceted; particles with a diameter below 5 μm in the atmosphere can enter the human bronchi and even the deep portions of the lungs. It is reported that when the concentration of such fine particles in the atmosphere is 100 μg/m³, respiratory tract infections in children increase significantly, and when the concentration is 200 μg/m³, the mortality rate of children from chronic respiratory diseases increases. To reduce the hazards caused by smoke-and-dust pollution to the human body, air treatment units are installed in many places.

[0022] Referring to FIG. 1, an improved smoke-and-dust air treatment unit comprises a box body, a first filtering space 10, a second filtering space 18, and a third filtering space 15 being separately provided in the box body, the first filtering space 10 communicating with the second filtering space 18, and the second filtering space 18 communicating with the third filtering space 15.

[0023] An air inlet 22 is defined at the top of the first filtering space 10, and an induced draft fan 21 communicating with the air inlet 22 is provided in an inner cavity of the first filtering space 10; an activated carbon filter plate layer 23 is fixedly provided on a side of the air inlet 22 facing the inner cavity of the first filtering space 10; a water tank 13 is provided at a lower portion of the inner cavity of the first filtering space 10 at a position corresponding to the air inlet 22.

[0024] A plurality of filter plate layers 20 are arranged in an array at the position where the first filtering space 10 communicates with the second filtering space 18; a plurality of light-transmitting windows 19 are defined in the second filtering space 18, and a transparent glass layer is hermetically fixed at each light-transmitting window 19; a photocatalytic material layer is coated on an inner cavity wall of the second filtering space 18.

[0026] The operating principle of the present utility model is as follows: after the power switch is turned on, the induced draft fan 21 and the exhaust fan 17 are started respectively; under the action of the induced draft fan 21, smoke-and-dust air passes from the air inlet 22 through the activated carbon filter plate layer 23 and enters the first filtering space 10; a portion of the dust of relatively large volume falls into the water tank 13; the induced draft fan 21 causes the air to flow in the first filtering space 10, and the air penetrates the multiple filter plate layers 20 and enters the second filtering space 18; in the second filtering space 18, the air is sterilized by irradiation of sunlight in combination with the action of the photocatalytic material layer; the air then enters the third filtering space 15, where it is sterilized by the ultraviolet light bars 14, after which, under the action of the induced draft fan 21, the air that has completed the three-layer filtration is discharged through the air outlet 16.

[0027] As a preferred embodiment, the number of filter plate layers 20 is three, and the filter plate layers 20 are, in sequence, an anti-mite filter plate layer, a deodorizing filter plate layer, and a formaldehyde-removing filter plate layer.

[0028] As a preferred embodiment, the number of ultraviolet light bars 14 is one or more.

[0029] Referring to FIG. 2, as a preferred embodiment, one side of the water tank 13 extends, via a water inlet pipe 11, through to the outside of the box body and communicates with a water supply device 32, and the other side of the water tank 13 extends, via a water outlet pipe 12, through to the outside of the box body and communicates with a sewage reservoir 33; a water pump 34 is connected between the water outlet pipe 12 and the sewage reservoir 33. The water supply device 32 supplies clean water to the water tank 13, and the water in the water tank 13 is replaced periodically; the water pump 34 discharges the waste water along the water outlet pipe 12 into the sewage reservoir 33, and the water supply device 32 then delivers clean water through the water inlet pipe 11 into the water tank 13 for continued use. Through the provision of the water tank 13, re-entrainment of dust, which would affect the filtration effect of the next stage, is avoided.

When the motor 31 is started, the power output of the motor 31 drives the fan blades 28 to rotate via the rotating shaft 29, thereby increasing the air flow velocity in the first filtering space 10 by means of the fan blades 28.

[0031] Referring to FIG. 2, as a preferred embodiment, a fragrance mechanism 27 is fixedly provided in the third filtering space 15 on an inner cavity wall adjacent to the air outlet, the fragrance mechanism 27 comprising a fan 24 fixed to the inner cavity wall of the third filtering space 15 and a fragrance box 25 communicating with an air outlet of the fan, and a plurality of ventilation holes 26 being defined in the fragrance box 25 at positions corresponding to the air outlet of the fan. When the fan 24 is started, the air from the fan 24 blows toward the fragrance box 25, and the fragrance in the fragrance box 25 is emitted through the ventilation holes 26 into the third filtering space 15 and then, under the action of the induced draft fan 21, discharged out of the box body, so that the product can emit fragrant air according to the needs of the use environment.

[0032] The above-described embodiments merely express several implementations of the present utility model, and the descriptions thereof are relatively specific and detailed, but they should not be construed as limiting the patent scope of the present utility model. It should be noted that, for a person of ordinary skill in the art, various modifications and improvements may further be made without departing from the concept of the present utility model, and such modifications and improvements all fall within the protection scope of the present utility model.
