Abstract

The invention provides a porous ceramic dust remover which comprises an emergency bypass device, an installation fixing device and a rapid connecting device, wherein the emergency bypass device is provided with a valved cylinder equipped with an electromagnetic valve, a valve plate is arranged at the bottom of the cylinder, the top of the cylinder is equipped with an air inlet pipe and a copper air nozzle, the valved cylinder is mounted on a base, air holes are formed in two sides of the base, and a round graphite gasket used for sealing is arranged at the periphery of a partition bypass hole; one end of a porous ceramic tube in the installation fixing device forms arc transition, a tube seal cushion is manufactured into a biarc shape forming a certain clearance with the porous ceramic tube and is attached to a tube nest and the porous ceramic tube, the top of the porous ceramic tube is equipped with a graphite flat washer, a tube pressing plate is fixed on the tube nest through bolts; one end of a blowing elbow in the rapid connecting device is welded with a connecting end with a tapered structure, one end of a long spray tube with a nozzle is also welded with the connecting end, the blowing elbow and the long spray tube are connected and tightly locked by a stainless steel clamp with a groove formed in an inner ring, and a seal ring is arranged between the blowing elbow and the long spray tube.

Description

technical field [0001] The invention relates to a flue gas dedusting device, in particular to a porous ceramic deduster. Background technique [0002] Porous ceramic dust collector has outstanding advantages such as high temperature resistance, corrosion resistance, cleaning resistance, high mechanical strength, stable structure without deformation and long life, so it is considered to be the best choice for hot particle filter materials. The porous ceramic dust collector has high separation efficiency, and the dust removal rate can generally exceed 99.99%. Its filtration performance, especially for fine particle filtration below PM2.5, is unmatched by other dust removal and dust collection equipment. In addition, the microporous ceramic filter membrane will not produce secondary pollution, and is the most suitable and promising method for various waste gas treatment. [0003] However, because the sintering flue gas in many industries has the characteristics of high emissio...
