Embodiment 1

[0021] Embodiment 1, with reference to figure 1 , 2 , a double-layer cyclone separator rotating parallel dust removal device, mainly composed of a central cylinder 14, a middle cylinder 27, and an outer cylinder 23 arranged coaxially, with cavities between them, and sealed and isolated from each other. The lower part of the cylinder is a cone structure, and the cone ends of the middle cylinder 27 and the outer cylinder 23 are inner and outer bottom outlets 10, 24, and the inner and outer bottom outlets 10, 24 pass through the flange and the ash discharge device 6 connection; the upper end of the cavity between the intermediate cylinder 27 and the outer cylinder 23 is provided with a tangential inlet 22; several small cyclone separators 28 are distributed in the cavity of the intermediate cylinder 27 in double layers, and the outer layer Several cyclone separators in the three cylinders are evenly fixed on the inner wall of the middle cylinder 27 with the center of the three ...

Embodiment 2

[0024] Embodiment 2, with reference to figure 1 The bottom trough 17 of the ash discharge device communicates with the central cylinder 14 through the sewage pipe 30 to solve the problem of dust accumulation in the central cylinder 14 . The rest are the same as embodiment 1.

[0025] The working process of the present invention: the dust-laden air flow enters the upper end of the cavity between the outer cylinder body 23 and the middle cylinder body 27 tangentially from the tangential inlet 22 to generate a swirling flow, and perform first-stage separation under the action of centrifugal force. The separated coarse particles or liquid droplets will fall to the inner wall of the cone at the lower end of the outer cylinder 23 and be discharged through the outlet 24 of the outer bottom. The airflow through the first stage of separation enters the bottom of the intermediate cylinder 27 through the air inlet ring hole 26, and then rotates into each cyclone separator 28 from the a...

Abstract

A double-layer cyclone separator rotating parallel dust removal device, mainly composed of a central cylinder, an intermediate cylinder, and an outer cylinder that are coaxially arranged, have cavities and are sealed and isolated from each other. The upper end of the cavity between the outer cylinders is provided with a tangential inlet; several small cyclone separators are distributed in double layers in parallel in the cavity of the middle cylinder, and the several small cyclone separators in the outer layer are arranged in the center of the three cylinders. The shaft is evenly fixed on the inner wall of the middle cylinder, and several small cyclone separators in the inner layer are evenly distributed between the outer cyclone separator and the central cylinder. The invention solves the problems of low dust removal efficiency and uneven gas volume distribution of multiple cyclone separators in the existing boiler.

Description

technical field [0001] The invention relates to a double-layer cyclone separator rotating parallel dust removal device, in particular to a double-layer cyclone separator rotating parallel dust removal device capable of capturing fine particles (PM2.5). Background technique [0002] Air pollution is one of the important factors affecting our country's environment, among which dust pollution is an important part of air pollution. Studies have shown that fine particulate matter (PM2.5) in dust is easy to enrich heavy metals, acid oxides, organic pollutants, bacteria and viruses in the air, and its harm to human health is much higher than that of coarse particulate matter. Therefore, it is of great significance to control dust pollution, especially the emission of ultrafine particles. (Zhang Danian, Research on Inhalable Particulate Matter in Urban Atmosphere, [J] Shanghai Environmental Science, 1999, 18(4): 154-157). [0003] Cyclone separators are widely used in industrial d...
