Abstract
The dust removal device comprises an inclined tube grating and a water mist device, wherein the water mist device is arranged on the upstream side of an air flow, and the inclined tube grating is arranged on the downstream side of the air flow. The invention also discloses a dust removal method implemented by using the inclined tube wet type high-efficiency dust removal device. The invention can improve the dust removal efficiency and the dust removal wind speed, reduce the dust removal water mist consumption and greatly reduce the dust removal cost.
Description
Technical Field
The invention relates to the field of environmental protection, in particular to a wet dust collector which is particularly suitable for underground mine dust collection.
Background
Dust is one of occupational hazards and needs to be subjected to dust removal treatment. At present, the underground mine mainly adopts wet dust removal due to the environmental particularity, for example, the wet resonance grid dust removal technology is widely applied due to relatively high efficiency and small ventilation resistance, but the underground mine has high dust removal water mist consumption, small dust removal wind speed and needs to further improve the dust removal efficiency.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the inclined-tube wet-type efficient dust collector overcomes the defects in the prior art, improves the dust collection efficiency and the dust collection air speed, and reduces the dust collection water mist consumption.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the inclined tube wet-type efficient dust removal device comprises an inclined tube grating and a water mist device, wherein the water mist device is arranged on the windward side of a windstream, and the inclined tube grating is arranged on the leeward side of the windstream.
Further, the inclined tube aperture and the inclined angle of the inclined tube grating are determined according to the size of dust particles.
Furthermore, the inclined tube grating can be used as an electrostatic dust removal panel to form a wet electrostatic dust collector.
The dust removal method implemented by the inclined tube wet-type efficient dust removal device comprises the following steps:
the water mist device is arranged on the windward side of the windward flow, the inclined tube grating is arranged on the windward side of the windward flow, and the dust-containing gas and the dust-removing water mist are mixed and then enter the inclined tube grating from bottom to top: firstly, film making and dust catching are carried out for multiple times; secondly, the dust particles move downwards against the wind under the action of gravity and are separated from the air; thirdly, the dust particles are separated from the air by the wall attaching effect in the inclined tube; dust and the wall surface of the inclined tube are subjected to friction electrostatic adsorption and are separated from air, so that high-efficiency dust removal is achieved; and discharging the dust-containing sewage from an air inlet of the inclined tube grating, and discharging the purified air from an air outlet of the inclined tube grating.
The invention has the beneficial effects that: the water mist in the inclined tube is molded for multiple times to capture dust, so that the water film consumption can be greatly reduced; various dust removal effects are generated in the inclined tube, and the dust removal efficiency is high. The invention can greatly reduce the dust removal cost and improve the dust removal efficiency.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: 1-inclined tube grating, 2-water mist device, 3-direction of dust-containing gas, 4-direction of purified air and 5-direction of dust-containing sewage.
Detailed Description
The invention is further explained with reference to the drawings and the embodiments.
Examples
Referring to fig. 1, the inclined tube wet type efficient dust removal device comprises an inclined tube grating 1 and a water mist device 2, wherein the water mist device 2 is arranged on the windward side of a wind flow, and the inclined tube grating 1 is arranged on the leeward side of the wind flow.
In the embodiment, the inclined tube of the inclined tube grating 1 has an inclined angle of 35 degrees and an aperture of 8mm, adopts an aluminum alloy tube and has a length of 200 mm.
The dust removal method implemented by the inclined tube wet-type efficient dust removal device comprises the following steps:
arrange water smoke device 2 in the windward side of the distinguished and admirable leeward side and arrange pipe chute grid 1, go on in the pipe chute grid from the bottom up after dusty gas mixes with the dust removal water smoke: firstly, film making and dust catching are carried out for multiple times; secondly, the dust particles move downwards against the wind under the action of gravity and are separated from the air; thirdly, the dust particles are separated from the air by the wall attaching effect in the inclined tube; dust and the wall surface of the inclined tube are subjected to friction electrostatic adsorption and are separated from air, so that high-efficiency dust removal is achieved; and discharging the dust-containing sewage from an air inlet of the inclined tube grating, and discharging the purified air from an air outlet of the inclined tube grating.
The dust removal efficiency of the embodiment is 99.21% of the dust removal efficiency and 99.45% of the total dust removal efficiency.
