Anti-frosting glass fibre bag-type dust removal equipment for drying machine

Abstract

The invention discloses anti-frosting glass fibre bag-type dust removal equipment for a drying machine. The anti-frosting glass fibre bag-type dust removal equipment for the drying machine comprises an upper box body and a lower box body; the upper box body is separated from the lower box body through a partition mesh; an air inlet is formed in the lower box body, and an ash hopper is arranged at the lower part of the lower box body; a gravity dust separator is arranged at the air inlet; a dust discharging opening is formed in the bottom of the gravity dust separator; a gas outlet is formed in the top of the gravity dust separator; an air outlet and a maintenance gate are arranged on the upper box body; a plurality of filtering bags are arranged in the upper box body; the surface of each filtering bag is coated with a super-hydrophobic coating. According to the anti-frosting glass fibre bag-type dust removal equipment for the drying machine, the surface of each filtering bag is coated with the super-hydrophobic coating, and the filtering bags are arranged vertically, so that settled particles which are filtered by the surfaces of the filtering bags can fall off in time; the surfaces of the filtering bags are prevented from being blocked by the settled particles; the filtering bags can filter flue gas continuously, so that the filtered gas meets national environmental protection emission standards; meanwhile, the anti-frosting glass fibre bag-type dust removal equipment for the drying machine does not require an ash cleaning device.

Description

technical field [0001] The invention relates to the field of bag-type dedusting equipment, in particular to an anti-frost glass fiber bag-type dedusting equipment for dryers. Background technique [0002] Drying is an important part of the raw material preparation process. Most cement plants in my country use dryers to dry raw materials, but the waste gas discharged from the dryer is one of the main pollution sources of the cement plant. Therefore, how to treat the dryer as a cement One of the issues that the factory needs to focus on. At present, the bag filter is still the preferred method to purify the exhaust gas of the dryer. However, the dust removal efficiency of the dust collector is low, so that the purified gas cannot meet the national emission standards. Contents of the invention [0003] In view of this, the present invention provides an anti-frosting glass fiber bag-type dedusting device for a dryer, which can make the exhaust gas of the dryer comply with the...
