[0033] It can be understood that one end of the box 11 is provided with a dust gas flow inlet 23, and the other end is provided with a dust removal gas flow outlet 21; according to the flow direction of the dust gas flow, the dust gas flow inlet 23 is located in front of the magnetite powder suspension atomization unit, and the dust removal gas flow outlet 21 is located behind the axial flow fan 22.

[0034] In implementation, the specific dust removal method process is as follows:

[0035] Step 1: turn on the axial flow fan 22 to generate negative pressure in the box 11, and the dust gas flow is sucked into the box 11 after flowing through the dust gas flow inlet 23, and the magnetite powder suspension atomization unit sprays the atomized droplets of the magnetite powder suspension into the box 11, and at the same time, the magnetite powder in the atomized droplets is broken again to obtain atomized droplets with smaller particle size, and the atomized droplets collide with the dust gas flow, and in the collision process, the dust in the dust gas flow is captured by the atomized droplets to form solid-liquid two-phase droplets, and the dust gas flow is once dust removal, and part of the solid-liquid two-phase droplets fall down, and the rest of the solid-liquid two-phase droplets continue to flow;

[0038] Step 4: The dust removal airflow passes through the micropores of the dust removal microporous membrane 6 and the plate holes of the electromagnet hole plate 7, and finally flows out from the dust removal airflow outlet 21, completing the dust removal of the dust airflow.

[0039] Step 5: After dust removal, the electromagnet hole plate 7 is powered off, so that the magnetite powder is separated from the surface of the dust removal microporous membrane 6 away from the electromagnet hole plate 7, and the recycling of the magnetite powder is completed.

[0043] From the perspective of dust fluid flow, the radial cross-sectional shape of the box body 11 is circular, that is, the shape of the box body 11 is cylindrical or rectangular columnar.

[0044] Correspondingly, the shapes of the dust removal microporous membrane 6 and the electromagnet hole plate 7 are also circular or rectangular, and the two are located in the middle part of the box body 11, and the dust removal microporous membrane 6 and the electromagnet hole plate 7 are fixedly connected by bolts.

In this way, the inlet dust concentration at the dust gas inlet 23 is monitored in real time through the inlet dust concentration monitor 16, the outlet dust concentration at the dust-removed gas outlet 21 is monitored in real time through the outlet dust concentration monitor 17, if the inlet dust concentration and / or the outlet dust concentration exceeds a threshold value, the flow of the dust gas is reduced, the flow of the atomized droplets of the magnetite powder suspension is increased and / or the flow of the spray water is increased, so as to be able to improve the dust removal capacity of the double-adsorption type solid-liquid two-phase flow dust removal device and effectively ensure the dust removal effect of the double-adsorption type solid-liquid two-phase flow dust removal device.
