Embodiment 1
[0043] see figure 1 , a dust removal device for flue gas treatment, comprising a device body 1, a transparent airtight door 2 is installed on the outer end of the device body 1, an exhaust port 32 and an air inlet 31 are fixedly connected to the upper and lower ends of the device body 1, and the air inlet 31 and the exhaust port 32 are communicated with the device body 1 .
[0044] see figure 2 , the bottom end of the device body 1 is fixedly connected with a raised air cover 5, the cross section of the raised air cover 5 is a symmetrical parallel trapezoid, and the raised air cover 5 is a solid structure, so that the raised air cover 5 presents a convex shape as a whole , so that the space enclosed between the outer surface of the raised air cover 5 and the device body 1 can not be blown by the smoke, effectively preventing the larger particles of dust falling from the dust suction curtain from being easily blown up by the smoke; the device A half-pass filter plate is clam...

The invention discloses a dust removal device for flue gas treatment and a dust removal method thereof, and belongs to the field of flue gas dust removal. According to the dust removal device for flue gas treatment, through the arrangement of a plurality of dust collection curtain cloth, small-particle dust in flue gas can be adsorbed before the flue gas reaches a semi-pass filter plate, the contact amount of small-particle dust in smoke dust and the semi-pass filter plate is effectively reduced, and thus the condition frequency of the filter plate is remarkably reduced, the influence on the flue gas treatment efficiency is reduced, in addition, during flue gas treatment, in cooperation with inert gas introduction operation, transverse airflow can be formed in the device body, on one hand, the transverse airflow can blow the dust collection curtain cloth, and enable the cloth to contact with the flue gas more sufficiently, on the other hand, rising flue gas can be effectively dispersed through transverse airflow, the shuttling duration of the flue gas in the multiple pieces of dust collection curtain cloth is prolonged, small-particle dust in the flue gas can be more sufficiently attached to the dust collection curtain cloth, and the flue gas treatment efficiency is remarkably improved.
Description
technical field [0001] The invention relates to the field of flue gas dust removal, and more specifically, to a dust removal device for flue gas treatment and a dust removal method thereof. Background technique [0002] Smoke is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and pyrolysis products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10um, especially the 1-2.5um floating dust is the most harmful. The harm to the human body depends on the composition, concentration, d...
