| comparative dimension | titanium rod filter | Bag filter |
|---|---|---|
| Core filter element | Porous titanium rod made from industrial high-purity titanium powder (99.4%) by cold isostatic pressing and high-temperature vacuum sintering | Filter cloth made of materials such as polyester (PE), polypropylene (PP), nylon (NO), etc., with a surface treated with singeing and calendering to prevent fiber shedding |
| Filtering principle | Deep filtration, intricate and circuitous pores on the pipe wall, impurities forming a 'bridging phenomenon' in the pores, and a dense filter layer forming on the surface for dual filtration | Surface filtration is the main method, and the filtrate penetrates through the filter bag. Impurities are directly trapped on the surface of the filter bag, and some deep filter cloths can achieve preliminary deep filtration |
| Core performance parameters | 1. Filtration accuracy: 0.1-30 μ m (some can reach 100 μ m) 2. Working pressure: ≤ 1.0MPa (conventional ≤ 0.6MPa) 3. Working temperature: ≤ 300 ℃ (wet state) 4 Filtration efficiency:>99% 5 Processing flow: 0.15-100T/h | 1. Filtration accuracy: 0.5-1000 μ m2. Working pressure: ≤ 0.5MPa. 3. Working temperature: ≤ 80 ℃ Filtration efficiency: about 90% 5 Processing traffic: 20-500T/h |
| corrosion resistance | Excellent, the titanium surface forms a dense oxide film that can resist corrosion from strong acids (except HF), strong bases, and organic solvents | Better, depending on the material, PP/PE material can withstand conventional acid and alkali, but it is prone to aging and damage in strong corrosive environments |
| Regeneration and maintenance | Repeatable regeneration: 1 Use 0.3MPa clean water to backwash the new filter element for 1-3 minutes; 2. After multiple ineffective backflushing, soak and clean with a 5% hydrochloric acid/8% sulfuric acid/10% NaOH solution; 3. Service life of 4-5 years | No regeneration: After blockage, the filter bag needs to be replaced directly, which is convenient to replace; Some filter bags can be reused in the short term after cleaning, but the filtration effect decreases significantly; Single bag service life 1-3 months |
| Equipment cost and operating expenses | 1. Initial cost: High (titanium and sintering process costs are high) 2 Operating costs: Low (renewable, minimal replacement of consumables) 3 Maintenance cost: Low (only requires regular cleaning, no frequent replacement of parts) | 1. Initial cost: Low (filter bag material cost is low, equipment structure is simple) 2 Operating costs: high (frequent replacement of filter bags, high cumulative cost of consumables) 3 Maintenance cost: Medium (replacement operation is simple, but labor and consumables costs account for a large proportion) |
| Applicable industries and scenarios | 1. Pharmaceutical: Decarbonization filtration for large infusion and injection (compliant with GMP standards) 2 Chemical Industry: Strong Corrosion, High Temperature Reaction Liquid Filtration 3 Food: High temperature syrup, fruit juice clarification and filtration 4 Electronics: High purity fluid filtration | 1. Water treatment: pre-treatment of municipal sewage and industrial wastewater 2 Paint: pigment, resin, coarse filtration 3 Food: Edible oil, beverages preliminary impurity removal 4 Metallurgy: filtration of coolant and lubricating oil (high flow scenarios) |
| Core strengths | High precision, high temperature resistance, corrosion resistance, long service life, stable filtration, and no secondary pollution | High flow rate, low cost, easy replacement, compact structure, and large pollutant capacity |
| Main limitations | High initial investment, low cost-effectiveness in low flow scenarios, and easy blockage of pores by high viscosity fluids | Limited accuracy, poor high temperature resistance, unsuitable for strong corrosive environments, high consumption of filter bags |
