  I. Candle Filter - A New Weapon for Chemical Filtration

In the complex processes of chemical production, the filtration process is like a "purifier for the industrial blood vessels", directly affecting product quality, production efficiency and cost control. Traditional filtration equipment has limitations in terms of precision, efficiency and adaptability to complex working conditions. As a new solution, the candle filter, with its unique design and technological advantages, is becoming an important choice for solid-liquid separation in the chemical industry.

 II. Analysis of the Working Principle and Core Advantages of the Candle Filter

1) The "Core Code" of Intelligent Filtration

The candle filter is an automated pressure filtration device. Multiple filter cartridges in the cylinder are covered with special filter cloth. The liquid is driven by pressure to pass through the filter cloth, and solid particles form a "filter cake layer" on the surface. The micropores of the filter cake are used to intercept impurities at the micron level or even sub-micron level. When the pressure difference reaches the set value, the back-blowing and cake removal program is automatically started. After the filter cartridges are regenerated, they enter the next cycle to achieve continuous operation.

2) Four Advantages to Meet the Needs of Chemical Production

2.1 Outstanding Precision: It has the ability to filter at the micron level and can meet the strict requirements for impurity control in fields such as electronic chemicals and pharmaceutical intermediates.

2.2 High Processing Efficiency: The design of multiple filter cartridges expands the filtration area, and a single device can handle large-scale production scenarios, such as the daily processing of ten thousand tons of crude oil.

2.3 Economic and Environmental Protection: The filter cartridges can be reused through backwashing, reducing the consumption of consumables and downtime, and lowering the overall cost.

2.4 Intelligent and Controllable: It integrates systems such as pressure sensing and frequency conversion regulation, supports remote monitoring and automatic parameter adjustment, and improves production safety and management efficiency.

 III. Deep Cultivation in Multiple Areas of the Chemical Industry: Filtration Solutions for the Whole Process

1) Fine Chemicals: A Key Helper for Quality Upgrade

In the production of pigments, coatings and catalysts, the candle filter accurately separates particulate impurities. In pigment production, it ensures color purity; in coating filtration, it improves transparency; and in catalyst recovery, it extends the service life. It is especially suitable for fine-grained scenarios with low flow rates and high purity.

2) Petrochemical Industry: Guarantee for the Stable Operation of the Whole Process

From the initial purification after crude oil extraction (removing silt and suspended matter), to filtering impurities in catalytic cracking during the oil refining process and removing 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 the continuous operation of production capacity.

3) Pharmaceutical Chemical Industry: A Compliant Choice for Clean Production

It meets the requirements of GMP regulations and is used for the purification of raw materials for pharmaceuticals, purified water for injection, the filtration of antibiotic fermentation broth and the guarantee of a sterile environment in vaccine production. The renewable characteristics of the filter cartridges reduce the risk of cross-contamination and conform to the standards of the pharmaceutical industry for safety and clean production.

4) More Scenarios: Customized Solutions to Solve Industry Problems

For scenarios such as the purification of chemical fertilizer slurries, the filtration of pesticide intermediates and the refining of raw materials for daily chemicals, materials (such as 304/316L stainless steel, titanium materials, etc.) and filter cloth (such as PP/PE/PTFE) can be customized according to the characteristics of materials (such as acidity and alkalinity, temperature, viscosity, etc.) to achieve precise filtration.

 IV. Three Key Elements to Ensure the Effect

1) Material Selection: Durable Options Adapted to Working Conditions

1.1 Cylinder: 304 stainless steel is selected for weakly corrosive scenarios, 316L stainless steel is used in strong acid and strong alkali environments, and titanium materials are adopted in high-temperature, high-pressure and strongly corrosive working conditions to balance safety and economy.

1.2 Filter Cartridge: PP/PE materials can be selected for conventional scenarios, PPS is used in high-temperature and highly corrosive environments, PTFE is adopted in high-demand fields such as electronics and pharmaceuticals, and stainless steel filter cartridges are suitable for high-pressure environments.

1.3 Filtration Area: Precise Matching of Flow and Efficiency

Combining the viscosity of materials, particle concentration, filtration precision and production cycle, the filtration area is dynamically adjusted through correction coefficients, and the arrangement of filter cartridges is optimized to ensure stable operation under large flow conditions.

1.4 Automation Control: The Core Support for Intelligent Production

The pressure sensor monitors the pressure difference in real time and automatically triggers back-blowing and cake removal. The frequency converter adjusts the feed flow to maintain stability. The preset cleaning cycle and fault alarm system reduce manual intervention and improve equipment reliability.

 

 V. Future Trends:

1) Embarking on a New Journey with the Chemical Industry

As the chemical industry transforms towards high-end, green and intelligent directions, the candle filter will undergo technological upgrades:

1.1 High-end: Research and develop new filter cartridge materials to meet the high-precision filtration needs in cutting-edge fields such as semiconductor chemicals.

1.2 Green: Optimize the back-blowing and cleaning processes to reduce energy consumption and filter residue emissions and help the industry develop in a low-carbon manner.

1.3 Intelligent: Integrate the Internet of Things and big data to realize remote diagnosis of equipment, fault early warning and parameter self-optimization, and promote the automation process of production.

 

 VI. Opening up New Possibilities for Efficient Filtration

The candle filter, with its high precision, high reliability and high adaptability, provides innovative solutions for fields such as fine chemicals, oil refining and pharmaceutical production. With the in-depth integration of technological innovation and industry needs, this "industrial purifier" will continue to empower enterprises to improve quality, reduce costs and play a greater value in the track of green and intelligent production.
