Description

Magnetic suspension air blower based on backward flow flue gas recycle

Technical Field

The utility model relates to the technical field of blower flue gas treatment, in particular to a magnetic suspension blower based on backflow flue gas recycling.

Background

The air blower for the back flow reuse of fume is to suck part of the fume after dust removal into the air blower via the air inlet end of the air blower, form high pressure gas after passing through the air blower, exhaust the high pressure gas into the pipe network to drive the air system and exhaust the high pressure gas into the lime cooling air system. Because the oxygen content in the flue gas is low, the oxygen concentration in the combustion zone can be reduced, and the generation of nitrogen oxides can be inhibited. At present, the main connection mode is that a backflow flue gas pipeline is rigidly connected with an inlet of a blower, and flue gas directly enters the blower. Because the return smoke contains more impurities and ash residues and even scrap iron, and condensed water and the like are generated by cold-hot interaction between the smoke and a pipeline in the recovery process, the ash residues, the scrap iron and the condensed water respectively cause dynamic balance unbalance, abrasion and corrosion of a rotating part, and long-term stable operation of a blower cannot be ensured; some places are additionally provided with dust filtering, water filtering and residue filtering devices in the pipeline, but the dust filtering, water filtering and residue filtering devices are rigidly connected, and maintenance or replacement can be completed only by stopping production, so that huge economic loss is caused; meanwhile, when the smoke quantity is excessive or insufficient, the smoke quantity cannot be regulated or the air is taken out from the atmosphere, so that energy waste or insufficient air consumption is caused, the smoke index exceeds the standard, and the atmosphere is polluted.

Mechanical noise is generated in the running process of the fan, a sound bridge is generated through a rigidly connected pipeline, high-frequency and high-frequency noise is transmitted to the environment, and sound pollution is caused; the existing equipment wraps the fan through the sound insulation device, noise is reduced to a certain extent, but sound bridge noise propagation caused by rigid connection still cannot be changed, and meanwhile, heat of the main machine cannot be dissipated due to the sound insulation cover, so that reliability and stability of the air blower are reduced.
