Abstract

The invention relates to an airflow distribution device of an electric bag dust collector, which includes a housing, a first distribution plate, a second distribution plate, and a third distribution plate. The first distribution plate, the second distribution plate, and the third distribution plate are from From the outside to the inside, they are arranged in the casing of the reducing pipe in sequence. The upper panels of the first distribution plate and the second distribution plate are at 90° to the upper panel of the casing, and the upper panels of the first distribution plate and the second distribution plate are The lower panel is 90° to the lower panel of the housing, the shape of the third distribution plate is spherical, and the opening ratios of the airflow holes on the first, second and third distribution plates are 40%, 60%, and 80% respectively , the shapes of the airflow holes on the first, second and third distribution plates are five-pointed star, four-pointed star and three-pointed star respectively. This kind of device adjusts the flow velocity of the inlet airflow in the variable diameter pipe, so that the airflow is evenly diffused and distributed, the purification efficiency is improved, and the failure rate of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to an airflow distribution device of an electric bag dust collector. Background technique [0002] At present, the most widely used equipment for purification and recovery of smoke and dust emitted by iron and steel, cement, chemical industry, electric power and other enterprises is the electric bag dust collector. Generally, the high-speed dust-laden flue gas is introduced into the electric bag filter from the flue, and it transitions to the working room through the variable-diameter tubes with different calibers at both ends. Because the ratio of the diameter area of ​​the two ports of the variable-diameter tube is 5-9 times, the tube length It is only 3m, and the opening angle is as high as 60-70°. If the necessary measures are not taken in the reducing pipe, it will cause uneven air distribution and reduce the purification efficiency of the electric bag composite dust colle...
