Precision filtration is a core process in modern industry. Traditional PP and stainless steel filter elements are prone to corrosion, short service life and secondary pollution under complex working conditions such as strong acid, strong alkali, high temperature and high pressure. Relying on the properties of titanium metal and powder metallurgy sintering process, titanium rod filters have become key equipment in high-end manufacturing fields such as pharmaceuticals, chemical engineering and new energy.
I. Core Principles and Structure of Titanium Rod Filters
1. Microstructure and Sintering Process
Titanium rod filter elements are made of high-purity titanium powder, formed into a three-dimensional interconnected microporous structure through cold isostatic pressing and high-temperature vacuum sintering. They feature adjustable porosity and filtration precision, as well as excellent mechanical strength.
2. Depth Filtration Mechanism
Precision filtration is achieved through a combination of surface interception and depth retention, with large dirt-holding capacity and high filtration efficiency.
3. Overall Equipment Structure
It is mainly composed of a stainless steel shell, titanium rod filter element group, quick-opening top cover, positioning device, fluid interface and monitoring instruments. It has a compact structure and is easy to maintain.
II. Core Performance Advantages of Titanium Rod Filters
|
Core Performance Advantages |
Key Performance |
Application Value |
|
Super Corrosion Resistance |
A self-repairing passivation film forms on the titanium surface, resistant to strong acids and alkalis with pH 1-14 (including aqua regia and hydrofluoric acid) |
Solves corrosion failure, service life is more than 3 times that of stainless steel filter elements |
|
Excellent High Temperature Resistance |
Operating temperature: -269℃~300℃, aperture and precision remain unchanged under thermal expansion and contraction |
Direct filtration of high-temperature materials without cooling, simplifying processes and saving energy |
|
No Secondary Pollution |
Pure material, no particle shedding or dissolution, compliant with FDA and GMP standards |
Suitable for high-purity industries such as pharmaceuticals and food, ensuring product safety |
|
Repeated Regeneration |
Most pollutants are trapped on the surface, regeneration recovery rate >95% via multiple methods |
Reusable for more than 200 times, comprehensive cost is more than 40% lower than disposable filter elements |
|
High Mechanical Strength |
Stable sintered structure, not easy to deform or break, resistant to high pressure difference and backwashing |
Reliable operation, reducing downtime maintenance and improving production efficiency |
|
Environmentally Friendly and Recyclable |
100% recyclable titanium material |
Reduces waste disposal costs and meets green manufacturing requirements |
III. Application Examples in Multiple Industries
1. Pharmaceutical Industry
Meets GMP aseptic requirements with no secondary pollution. Widely used in decarbonization of large-volume infusions, fine filtration of APIs, sterilization of biological preparations, etc., with a filter element service life of 3-5 years.
2. Food and Beverage Industry
Does not affect product flavor, no filter aid required. Suitable for clarification and sterilization filtration of beer, fruit juice, edible oil, condiments, etc., increasing production efficiency by 30%.
3. Chemical and New Energy Industry
Withstands extreme working conditions of strong acid, strong alkali, high temperature and high pressure. It is the preferred equipment for purification of lithium battery cathode materials, filtration of electronic chemicals, and catalyst recovery.
4. Water Treatment Industry
Used as security filtration for membrane systems with stable effluent quality and long service life. It can realize deep reuse of industrial wastewater, with water resource recovery rate exceeding 85%.
IV. Filter Element Regeneration and Maintenance Methods
Three-step regeneration method for titanium rod filter elements:
- Physical cleaning: Backwash at a pressure difference of 0.1 MPa; use ultrasonic for stubborn particles, and steam backblowing for light oil contamination.
- Chemical cleaning: Alkaline cleaning for oil contamination, acid cleaning for scale (hydrochloric acid is prohibited), and alkaline cleaning followed by acid cleaning for complex contamination.
- Verification and drying: Rinse until conductivity meets the standard, conduct bubble point test for integrity, and store for later use after low-temperature drying.
