Online fault detection and protection method and system for bag type dust remover

Abstract

The invention relates to an online fault detection and protection method and system for a bag type dust remover and belongs to the technical field of bag type dust removers. A main air inlet pipe is connected with a temperature instrument and an air inlet valve; a bin chamber exhaust pipe is connected with an anemometer, a leak detector and a bin chamber switching valve; a main air exhaust pipe is connected with a dust concentration meter and the bin chamber exhaust pipe; an ash hopper is connected with a material level switch and a bin chamber ash discharging valve; the lower part of the ash discharging valve is connected with a solid flow switch; and the upper part of the ash hopper is connected with a dust removal bin chamber. The method and system provided by the invention have the advantages that the operation state of a cloth bag is detected in real time, safe and efficient operation of the bag type dust remover can be effectively protected, daily operation maintenance effect and maintenance efficiency of the bag type dust remover are improved, the probability of halt caused by tiny faults of the bag type dust remover is reduced, and a positive effect is produced in the practical project application.

Description

technical field [0001] The invention relates to an online fault detection and protection method and system of a bag dust collector, belonging to the technical field of bag dust collectors. Background technique [0002] The bag filter is a dry dust filter device. It is widely used in mining, metallurgy, building materials, chemical industry, light industry, environmental protection and other industrial sectors. Its working principle is that when the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the effect of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust will be retained. On the surface of the filter bag, the purpose of dust removal is achieved, and the gas is purified. [0003] The bag filter has many advantages, and the filtration efficiency is very high, which can usually reach more than 99%. Therefore, the gas discharged from the...

Problems solved by technology

However, the bag filter has obvious disadvantages, such as a large amount of labor to check and replace the filter bag, and poor working conditions; because the filter bag is made of woven filter cloth or non-woven felt, it will be affected by the temperature resistance of the material itself during use.
