Waste gas filtering device and treatment equipment

Abstract

The invention is suitable for the technical field of boiler waste gas treatment, and provides a waste gas filtering device which comprises a filtering shell, wherein an annular filtering net and an annular partition plate which are sequentially distributed from inside to outside are coaxially arranged in an inner cavity of the filtering shell; the area between the filter shell and the annular partition plate is divided into an air outlet cavity and an air inlet cavity by the two groups of baffles; the area between the annular partition plates is divided into a second filter cavity and a first filter cavity; a cleaning assembly, when the annular partition plate rotates, the baffles of the cleaning assembly clean the filtering surface of the annular filter screen. The invention further discloses waste gas treatment equipment which comprises the waste gas filtering device. The equipment further comprises a treatment shell, and the waste gas filtering device is detachably and fixedly arranged on the treatment shell. The waste gas filtering device provided by the embodiment of the invention has a good and efficient filtering effect on boiler waste gas; the waste gas treatment equipment provided by the embodiment of the invention can fully utilize heat in boiler waste gas.

Description

technical field [0001] The invention belongs to the field of boiler waste gas treatment, and in particular relates to a waste gas filtering device and treatment equipment. Background technique [0002] A large amount of dust will remain in the flue gas discharged from the boiler during normal operation. If the flue gas is directly discharged into the atmosphere, it will pollute the environment. Therefore, it is necessary to remove dust from the flue gas discharged from the boiler. [0003] The common method now is to pass the flue gas into the pool to allow the dust to enter the water to settle. However, passing the flue gas directly into the pool not only consumes a large amount of water, but also makes it inconvenient to clean up the dust deposited in the pool. In addition, there is also a plan to pass the flue gas into the dust removal bag, and the flue gas is passed into the dust removal bag to filter out the dust, so that the dust remains in the dust removal bag.
