Application of Solid-Liquid Separation Filter Cloth in Chemical Oxidizer Processes —— The critical role of centrifuge filter bags
In modern chemical production, oxidation reactions are an extremely common and critical process step. From the production of inorganic salts and fine chemicals to pharmaceutical intermediates, oxidizing agents—such as permanganates, hydrogen peroxide, persulfates, and nitrates—play a central role throughout both the reaction and separation stages. Meanwhile, the accompanying solid-liquid separation process often directly determines the purity, yield, and safety of the final product. As one of the core filtration units, the centrifuge filter bag’s material selection, structural design, and operational performance become essential factors in ensuring the system runs efficiently, reliably, and safely.
I. Challenges in Solid-Liquid Separation During Chemical Oxidizer Production
Chemical oxidizers often have Strong oxidizing properties, strong corrosiveness, and high reactivity Its characteristics include a production process that often involves acidic media, strong oxidizing solutions, or high-temperature reaction environments.
In the solid-liquid separation stage, common challenges include:
- Highly corrosive : The chemical stability required for filter cloth fibers is extremely high—ordinary polyester or nylon struggles to withstand it over the long term.
- Fine particles, prone to clogging : Oxidation products often appear as fine crystals or colloidal particles. If the filter cloth pore size is chosen improperly, it can lead to a decrease in filtration speed and clogging of the filter bags.
- Separation efficiency and filter cake washing requirements are high. : The filter cloth must not only enable rapid dewatering but also ensure that the filter cake remains intact and is easy to peel off.
- Security Protection Features : Some oxidizers pose risks of spontaneous combustion and explosion, so filter cloths must have antistatic or flame-retardant properties to prevent static buildup.
Therefore, in solid-liquid separation for the oxidizer industry, centrifuge filter bags are no longer a single filtration medium—they have become a versatile tool that combines multiple functions. Corrosion-resistant, temperature-resistant, oxidation-resistant, and explosion-proof for enhanced safety A systematic solution.
II. Structure and Performance Requirements for Centrifuge Filter Bags
Centrifuge filter bags are widely used in Various types of centrifugal equipment, including vertical, horizontal, scraper discharge, and bag-hanging discharge models. China. Its design not only affects filtration efficiency but also influences material discharge, filter bag replacement, and cleaning cycles.
1. Material Selection:
Commonly used high-performance fibers for chemical oxidizer environments.
2. Structural Design:
- Precise Aperture Control : By adopting a multi-layered composite structure or monofilament weaving technology, it achieves a balance between high throughput and anti-clogging performance.
- Strengthened Stitching and Edge Finishing : High-strength thread stitching, hot-melt, or ultrasonic welding methods are used to prevent filter bags from tearing or leaking material.
- Lining and Support Structure Optimization : Some centrifuge filter bags utilize a support mesh or skeletal structure to enhance the flatness of the filtration surface and improve mechanical strength.
3. Special feature processing:
- Surface Anti-stick treatment , enhancing filter cake release properties;
- Anti-static treatment , meeting the explosion-proof requirements for oxidizer production;
- Thermal Setting and Calendering Process Stabilize the aperture structure and enhance filtration accuracy.
