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.

The service life of filter cloth directly affects production efficiency and operating costs. Although filter cloth quality is the core factor determining its service life, "quality" is a comprehensive concept that covers the entire chain from raw materials to application and maintenance. The key factors influencing filter cloth service life fall into three categories: inherent properties of the filter cloth, process and operating conditions, and operation and maintenance practices.

This article introduces the working principle and advantages of cartridge dust collectors, which are widely used in pharmaceutical API, preparations and traditional Chinese medicine processing for their high filtration accuracy and compact structure. It analyzes the "high-requirement and high-risk" characteristics of pharmaceutical dust and related safety risks. Focusing on the core of filter cartridge material selection, it details three common materials (pharmaceutical-grade polyester fiber, PTFE microporous membrane, glass fiber composite) with their applicable scenarios, helping pharmaceutical enterprises choose suitable materials to meet GMP requirements and ensure production safety.

This guide explains how filter cloth porosity and air permeability boost filter press efficiency, solving 90% of common issues: slow cycles, wet cake, frequent replacements. It covers permeability ranges, troubleshooting, maintenance tips, custom industrial solutions, and free expert support.
