A Comprehensive Guide to Dust Filter Cages: Types, Measurement, and Installation

A Comprehensive Guide to Dust Filter Cages: Types, Measurement, and Installation Currently, the market primarily offers the following four main types of dust filter cages (also known as bag cages): Stainless Steel Cages: We make these cages from stainless steel, using grades like 201, 304, and 316. They are suitable for moderately corrosive environments or conditions with generally low to medium acid/alkali concentrations. However, due to their relatively high cost, customers often select stainless steel cages only for specific, specialized applications. Galvanized Cages: We manufacture these cages by welding cold-drawn wire using specialized equipment and then applying a galvanized coating. This galvanization significantly enhances the cage’s rust resistance and helps reduce potential […]

Diverter Valve Selection Guide: Key Considerations and Best Practices

Diverter Valve Selection Guide: Key Considerations and Best Practices In industrial piping systems, controlling material flow is essential. Diverter valves play a key role here. They reliably guide powders, granules, and other materials from one line to another. This guide explains how these valves work and how to select the right one. What is A Diverter Valve? A diverter valve is a flow control device. Its main function is to change the path of a material. It typically has one inlet and two or more outlets. The valve directs the full material stream to a chosen outlet. It does not mix or regulate flow, it simply switches the path. This […]

Detailed Explanation and Application Suggestions for Pulse-Jet Bag Filter Cleaning Technology

Detailed Explanation and Application Suggestions for Pulse-Jet Bag Filter Cleaning Technology Technology Principle and Core Mechanism The Pulse-Jet Bag Filter is one of the most widely used high-efficiency dust removal devices in the industrial field. Its core cleaning mechanism relies on compressed air pulse-jet technology. This technology releases high-pressure compressed air (usually 0.4-0.6 MPa) instantly. This action forms a high-speed air flow pulse. The pulse penetrates the dust layer on the filter bag surface. It makes the dust layer separate from the filter bag surface. The dust then falls into the hopper. This process regenerates the filter bag. The cleaning process has three stages: Compressed Air Injection Stage: The solenoid […]

Causes and Solutions for Dust Filter Bag Detachment

Causes and Solutions for Dust Filter Bag Detachment Industrial dust collection systems widely use baghouse filters for their high filtration efficiency. However, many companies face problems with filter bags detaching during operation. Users often blame the bag manufacturers, but most detachment issues actually stem from improper dust collector design or installation. This article analyzes the root causes and provides practical solutions. How Tube Sheet Holes Affect Bag Detachment Key Functions of Tube Sheets The tube sheet (or hole plate) is a critical component in baghouse filters. It serves two main purposes: Separates the dirty gas chamber from the clean air chamber Provides precise positioning for filter bag installation Ideally, the […]
