Problems solved by technology

The problem is that it is difficult for masks or filters to filter small particles of dust, such as small particles of pm2.5 and below, which will still enter the lungs of the human body and accumulate, seriously affecting health
[0005] Chinese patent document CN 103272465 A discloses a portable smog purification device, which uses two-stage water washing to purify the air, and uses a small air pump as the power source. The existing problem is that the structure is relatively complicated and the battery life is short.

Embodiment 1

[0029] like figure 1 As shown in , a portable dust removal device includes a housing 7, and the air inlet pipe 1 communicates with the lower part of the housing 7. In this example, the air inlet 4 of the air inlet pipe 1 is preferably arranged at the bottom of the housing 7, and the housing The upper part of 7 is communicated with face mask 9 through connecting pipe 8, is provided with liquid 12 in housing 7, is provided with gas phase labyrinth 5 in housing 7 inner cavity, and described gas phase labyrinth 5 is provided with adsorption layer 53 at least on the windward side, Of course, it is also feasible to arrange more adsorption layers 53 . Different from the prior art, the present invention reduces the dust in the air by means of adsorption, keeps the adsorption layer 53 moist through the liquid 12, and absorbs the dust and fine particles in the air. Due to this structure, the present invention has almost no wind resistance, thereby not affecting normal breathing. see ...

Embodiment 2

[0042] The inventor found that the combination of water washing and adsorption can further improve the effect of dust removal, but it is still lower than expected, especially the effect of water washing is lower than expected. For example, Chinese patent document CN 103272465 A discloses a portable haze For the purification device, even after two-stage water washing, the dust removal effect is only 40%~70%, and it is related to the airflow velocity. When the airflow velocity increases, the dust removal effect tends to decrease. After careful analysis, it was found that during the washing process, due to the existence of air bubbles, under the influence of the surface tension of water, the contact between dust and water was not sufficient, thus affecting the effect of washing and dust removal.

[0043] For overcoming above-mentioned technical problem, on the basis of embodiment 1 as figure 2 In the optimized scheme shown in, the bottom of housing 7 inner cavity is also provide...

Embodiment 3

[0046] On the basis of embodiment 1 and 2, optional scheme such as Figure 4 Among them, the inlet pipe 1 is connected to the inlet of the gas-phase labyrinth 5, the outlet of the gas-phase labyrinth 5 is connected to the inlet of the liquid-phase labyrinth 6, and the outlet of the liquid-phase labyrinth 6 is connected to the exhaust port 13; Larger particles of dust, such as dust above pm10, and then through the liquid phase labyrinth 6 to absorb smaller particles of dust, can better exert the adsorption efficiency, especially can increase the adsorption capacity of the liquid in the liquid phase labyrinth 6, that is, it can absorb Change fluid after more particles. In particular, by using a liquid rich in negative ions as the adsorption liquid, such as rich in OH - Water with other negative ions can better absorb positively charged particles in the air, and this adsorption effect is more effective for smaller particles, such as dust below pm10.

Abstract

The invention relates to the field of haze prevention and control, in particular to a portable dust removing device which comprises a shell body. An air inlet pipe is communicated with the lower portion of the shell body. The upper portion of the shell body is communicated with a face mask through a connecting pipe. Liquid is arranged in the shell body. A gaseous phase labyrinth is arranged in a shell body inner cavity. The gaseous phase labyrinth is provided with an adsorption layer at least on a windward face. The arranged gaseous phase labyrinth is matched with the adsorption layer, the gaseous phase labyrinth lengthens an air path, meanwhile, air is turned by multiple times, through centrifugal force generated by turning, dust in air is in contact with the adsorption layer and is adsorbed by the adsorption layer, and accordingly dust and small particles in air are reduced. The principles are different from a filtering principle and a spraying principle in the prior art, compared with the filtering principle, the portable dust removing device is small in respiratory resistance, normal respiration can hardly be affected, by replacing liquid in the shell body, sediment is discharged, continues using can be achieved, using cost is low, and environment pollution can be avoided. Compared with the spraying principle, a power supply and a pump are of no need, using cost is lowered, and noise is removed.

Description

technical field [0001] The invention relates to the fields of dust removal and haze prevention, in particular to a portable dust removal device for haze prevention. Background technique [0002] In dusty working conditions, such as working in smoggy weather, most of the protective measures adopted in the prior art are masks or filter masks, and the dust in the air is filtered out by the filter discs in the masks or filter masks. The problem is that it is difficult for masks or filters to filter small particles of dust, such as small particles of pm2.5 and below, which will still enter the lungs of the human body and accumulate, seriously affecting health. Fine particles can be filtered by using more precise filters, but this also creates new technical problems. More precise filters are easily blocked by dust or fine particles, and the cost of frequent replacement of filters is higher, and replacement filters Cannot be recycled, causing new environmental pollution. And afte...
