Abstract

The invention discloses a denitration reactor pre-dedusting device, which comprises: a pre-dedusting unit, wherein the pre-dedusting unit comprises an outer shell, a connecting flue channel arranged in the outer shell, a dedusting maintenance assembly arranged in the outer shell, an air blowing assembly connected with the dedusting maintenance assembly, and a collecting box arranged at the bottom of the outer shell, and the two ends of the connecting flue channel extend outwards ; and a reaction unit comprising a denitration reactor, a maintenance platform arranged at the bottom of the denitration reactor, and a lifting assembly connected with the maintenance platform. According to the invention, the pre-dedusting unit is detachably mounted at one end of an existing denitration reactor to pre-treat coal ash in flue gas, so that the working efficiency of the denitration reactor is improved, normal operation of the device is guaranteed, and the denitration reactor is convenient to maintain and repair through the maintenance platform.

Description

technical field [0001] The invention relates to the technical field of flue dust removal, in particular to a pre-dust removal device for a denitrification reactor. Background technique [0002] In people's daily life and production activities, various types of boilers, kilns and other combustion devices are usually used. These combustion devices will inevitably emit a large amount of smoke and dust including coal dust, coke dust and toxic and harmful gases ( smoke). At present, flue dust purification usually only treats the sulfur in the flue gas, but the dust in the flue gas is directly discharged into the atmosphere, thereby inducing smog. The existing treatment methods and devices have unsatisfactory dedusting effects. During the desulfurization process, smoke and coal residues easily block the pipelines and affect the normal operation of the devices. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invent...
