Problems solved by technology

[0003] The flue gas often contains a large number of small particles of dust. During the flue gas treatment, the small particles of dust are generally intercepted through the filter screen. The cleaning frequency is high, which affects the treatment efficiency of flue gas

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 all in communication 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...

Abstract

The invention discloses a dust removal device for flue gas treatment and a dust removal method thereof, belonging to the field of flue gas dust removal. A dust removal device for flue gas treatment can be used before the flue gas reaches a half-pass filter plate by setting a plurality of dust suction curtains. Previously, the small particle dust in the flue gas was adsorbed, which effectively reduced the amount of small particle dust in the flue gas in contact with the half-pass filter plate, thereby significantly reducing the frequency of the filter plate and reducing the impact on the flue gas treatment efficiency. In addition, the flue gas treatment When combined with the operation of introducing inert gas, a horizontal airflow can be formed in the device body. On the one hand, the horizontal airflow can blow the dust-absorbing curtain to make it more fully contact with the smoke. On the other hand, the horizontal airflow can effectively disperse the dust The rising flue gas prolongs the time for the flue gas to shuttle through multiple dust-absorbing curtains, so that the small particles of dust in the flue gas are more fully adhered to the dust-absorbing curtains, and the treatment efficiency of the flue gas is significantly 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...
