In the complex processes of chemical production, the filtration link acts as the "purifier of industrial blood", directly affecting product quality, production efficiency and cost control. Traditional filtration equipment has limitations in precision, efficiency and adaptability to complex working conditions, while candle filters, as a new solution, are becoming an important choice for solid-liquid separation in the chemical industry by virtue of their unique design and technical advantages. - Candle Filters System
Candle Filters: Analysis of Working Principles and Core Advantages
Candle filter is an automated pressure-type filtration device. Multiple filter elements in the cylinder are covered with special filter cloth. Driven by pressure, the liquid passes through the filter cloth, and solid particles form a "filter cake layer" on the surface. The micro-pores of the filter cake are used to intercept micron-level or even sub-micron-level impurities. When the pressure difference reaches the set value, the backwashing and cake discharging program is automatically started. After the filter elements are regenerated, they enter the next cycle to achieve continuous operation.
Four Major Advantages Adapting to Chemical Production Needs
Outstanding Precision: It has micron-level filtration capacity, which can meet the strict requirements for impurity control in fields such as electronic chemicals and pharmaceutical intermediates.
High-efficiency Processing: The multi-filter element design expands the filtration area, and a single device can cope with large-scale production scenarios, such as ten-thousand-ton 级 crude oil daily processing.
Economic and Environment-friendly: The filter elements can be reused through backwashing, reducing consumable consumption and downtime, and lowering comprehensive costs.
Intelligent and Controllable: It integrates systems such as pressure sensing and frequency conversion adjustment, supporting remote monitoring and automatic parameter adjustment, and improving production safety and management efficiency.
Deeply Ploughing Multiple Chemical Fields: Full-process Filtration Solutions
Fine Chemicals: Key Support for Quality Upgrading
In the production of pigments, coatings and catalysts, candle filters accurately separate particle impurities. In pigment production, they ensure color purity; in coating filtration, they improve transparency; and in catalyst recovery, they extend service life, especially suitable for small-flow and high-purity fine chemical scenarios.
Petrochemicals: Guarantee for Stable Operation of the Full Process
From the initial purification of crude oil (removing sand and suspended solids) to the filtration of catalytic cracking impurities in the oil refining process and the removal of wax in lubricating oil production, its large-flow processing capacity and explosion-proof and corrosion-resistant design can reduce equipment wear and downtime losses, and ensure continuous production capacity operation.
Pharmaceutical Chemicals: A Compliant Choice for Clean Production
It meets the requirements of GMP regulations and is used for the purification of active pharmaceutical ingredients and water for injection, the filtration of antibiotic fermentation broth and the aseptic environment guarantee for vaccine production. The renewable characteristics of the filter elements reduce the risk of cross-contamination, in line with the safety and clean production standards of the pharmaceutical industry.
More Scenarios: Customized Solutions to Solve Industry Problems
For scenarios such as chemical fertilizer slurry purification, pesticide intermediate filtration and daily chemical raw material refining, materials (304/316L stainless steel, titanium, etc.) and filter cloth (PP/PE/PTFE) can be customized according to material characteristics (acidity, alkalinity, temperature, viscosity, etc.) to achieve precise filtration.
