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

[0030] Such as figure 1 As shown in , an electric 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 the body 7 communicates with the face mask 9 through the connecting pipe 8, a liquid 12 is provided in the housing 7, and a gas phase labyrinth 5 is provided in the inner cavity of the housing 7, and the gas phase labyrinth 5 is provided with an 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

[0031] The air inlet 4 of the air inlet pipe 1 or the air inlet pipe 1 is provided ...

Embodiment 2

[0048] 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.

[0049] 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

[0053] 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 provides an electric portable dust removing device, and relates to the field of haze prevention and control. The electric portable dust removing device comprises a shell, an air inlet pipe is communicated with the lower portion of the shell, the upper portion of the shell is provided with an exhaust opening used for being connected with a mask, liquid is arranged in the shell, a gas phase maze is arranged in an inner cavity of the shell, and the gas phase maze is provided with an absorbing layer at least on the windward face; an air inlet of the air inlet pipe is immersed into the liquid; the air inlet of the air inlet pipe or the air inlet pipe is provided with a one-way valve preventing the liquid from flowing back; a pressure sensor is arranged behind the one-way valve, an air supplement pump is further arranged, the inlet of the air supplement pump is communicated with the atmosphere, and the outlet of the air supplement pump is communicated with the inner cavity of the shell behind the one-way valve. Due to matching of the gas phase maze and the absorbing layer, dust and fine particles in the air are reduced; by means of the adoption of combination of the pressure sensor and the air supplement pump, pressure can be automatically increased according to breaths of a user, and accordingly breath resistance hardly exists.

Description

technical field [0001] The invention relates to the field of dust removal and haze prevention, in particular to an electric 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. ...
