Diaphragm puncture, cracking and pressure relief failure are the most common accessory faults in pulse dust removal systems. Most on-site maintenance personnel hold a misconception that diaphragm damage is simply caused by poor material quality or expired service life. In fact, the vast majority of diaphragm failures occur at the moment of system pressure peak. As the only vulnerable component unable to withstand peak impact in the entire pulse valve, the diaphragm fails prematurely mainly due to three core factors: structural stress characteristics, instantaneous pressure impact and cumulative fatigue damage.

As the core energy storage component of pulse dust removal systems, customized air reservoirs have achieved comprehensive optimization in structure, pressure resistance and air tightness. Customized according to actual on-site working conditions, the products are compatible with all types of large and small dust removal units. They deliver uniform and stable air supply, effectively improving the dust cleaning efficiency of filter bags. Manufactured and tested in strict accordance with pressure vessel standards, the air reservoirs feature deformation resistance, zero air leakage and excellent durability against harsh environments, greatly reducing equipment operation and maintenance costs. They serve as the preferred core accessories for industrial dust removal projects.

This article introduces the working principle of the dust collector housing, the core pressure‑bearing shell of bag‑type dust collectors, which cooperates with air receivers and pulse jet valves to complete continuous dust filtration and cleaning. It also analyzes the hazards of excessive pressure difference inside the housing, including filter bag damage, higher energy consumption, reduced dust‑removal efficiency, component failure and unstable production operation, reminding users to maintain normal pressure difference for long‑term stable system performance.

This paper summarizes the selection method of rubber diaphragms for electromagnetic pulse valves used in dust removal systems of power plants.Selection mainly depends on flue gas temperature, corrosive composition and compressed air quality.

As key equipment for industrial dust removal, the stable operation of bag filters is directly related to emission compliance and operation and maintenance costs. Aging and failure are the main causes of shortened filter bag service life, usually manifested as embrittlement, damage, bag clogging, corrosion, etc., which eventually lead to reduced dust removal efficiency and frequent equipment failures. This paper analyzes the aging mechanism from six dimensions: high-temperature thermal damage, chemical corrosion, mechanical abrasion, improper cleaning, hydrolysis and aging, as well as installation and operation defects. It also puts forward four corresponding solutions: material selection, process control, intelligent monitoring and standardized maintenance, providing a technical reference for enterprises to extend filter bag life and reduce overall operating costs.

This article details practical solutions to prevent industrial dust collector filter bag clogging caused by low-temperature condensation. The core is maintaining flue gas 20–30°C above the dew point, controlling air leakage, using dry cleaning air, optimizing insulation and cleaning systems. It covers temperature control, insulation, air leakage prevention, emergency handling, and daily maintenance, helping enterprises avoid system failure, reduce maintenance costs, and ensure stable equipment operation.
