Embodiment 1

[0015] Example 1: The emergency bypass device of the porous ceramic dust collector is installed inside the porous ceramic dust collector, specifically on the flower plate between the upper box and the lower box, and a circular bypass hole is opened in the middle of the flower plate. The device includes a valved cylinder (1) equipped with a solenoid valve, and a valve plate (5) is arranged at the bottom of the cylinder; the valve plate (5) is fixed by a nut (2), a flat washer (3), and a spring washer (4). Air intake pipe (6) and copper gas nozzle (7) are arranged. The cylinder with valve is installed on the base (8), and there are air holes on both sides of the base (8), and a round graphite pad (9) for sealing is arranged around the partition bypass hole (21). The up and down movement of the valve plate (5) is driven by the expansion and contraction of the valved cylinder (1). When the valve plate (5) stretches and moves downward, it can be closely attached to the graphite pad...

Abstract

An emergency bypass device for a porous ceramic dust collector. The emergency bypass device is inside the porous ceramic dust collector. The bypass system is installed on the flower plate between the upper box and the lower box of the dust collector. There is a circular bypass hole. This device includes a valved cylinder equipped with a solenoid valve. There is a valve plate at the bottom of the cylinder. The valve plate is fixed by nuts, flat washers and spring washers. The top of the cylinder is equipped with an air intake pipe and a copper air nozzle. The valved cylinder is installed on the base, and there are air holes on both sides of the base, and a circular graphite gasket for sealing is arranged around the bypass hole of the partition. The emergency bypass device has the characteristics of simple and reasonable structure, uniform stress, easy installation and low cost.

Description

technical field [0001] The invention relates to a flue gas dedusting device, in particular to an emergency bypass device for a porous ceramic dust collector. 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 ha...
