Abstract

The invention provides an electric bag dust remover capable removing PM2.5, and relates to the field of fuel gas purification. The electric bag dust remover comprises a box, an electric dust remover arranged in the box and a bag-type dust removing structure which is composed of a gas purification chamber and a filter bag arranged under the gas removing chamber. The electric dust remover is connected with a gas inlet, and the gas purification chamber is connected with a gas outlet. An electrode wire is arranged in the electric dust remover, a pulse valve is arranged over the gas purification chamber, a dust hopper is arranged under the box, and the overall box is fixedly supported by a support. The electric bag dust remover is structurally characterized in that a vertically-arranged partition plate is arranged between the electric dust remover and the gas purification chamber in the box, and uniformly-formed pores are formed in the partition plate. A surface layer of the filter bag is prepared from 65% of ultrafine PPS fibers and 35% of PTFE fibers, and base cloth of the filter bag is prepared from PTFE. Compared with the prior art, the electric bag dust remover has the advantages that a flow field in the dust remover can be improved, wear of dust to the filter bag can be reduced, the service life of the filter bag can be prolonged, and the dust removing efficiency can be improved.

Description

technical field [0001] The invention relates to the field of flue gas purification, in particular to an electric bag dust collector for the co-processing of multi-pollutants such as fine particle dust and PM2.5. Background technique [0002] With the sustained and rapid development of my country's economy, the process of urbanization and industrialization is accelerating, and various air pollutants have increased sharply. PM2.5, as the focus of national attention recently, is one of the main pollutants in the atmosphere. The content of PM2.5 in the atmosphere is very small, but because of its small particle size and large specific surface area, it absorbs a large number of viruses and harmful substances and stays in the atmosphere for a long time, which is difficult to remove. It is harmful to environmental climate change, air quality and human health. have important influences. Since the main source of PM2.5 is the emission of human activities, PM2.5 may adsorb carcinogen...
