Filter Thickener Advantage - Metal Membrane Filter Element
Material Characteristics
1. Based on the atomic-scale partial diffusion reaction synthesis technology, the pore structure can be accurately regulated at the micron and sub-micron levels, so that the material has a good filtration performance of uniform pore size distribution, high filtration accuracy, high open porosity, small zigzagging factor and low filtration resistance
2. The unique metal bond + covalent bond mixed crystal has the advantages of both metal and ceramic materials, which has excellent chemical stability, thermal stability, mechanical and physical properties, machinability, thermal conductivity and electrical conductivity.
3. The material preparation process is environmental, the whole life cycle of the material is environmentally friendly, recyclable and cost-effective
1. The titanium filter element has high filtration accuracy: the turbidity of the clearing liquid is < 5NTU,and it is clear and transparent.
2. Titanium filter element with high flux,The filtration flux per unit area is large and stable for a long time.
3. Low working pressure: the thickness of the filter element is about 2-3mm under the condition of ensuring strength, the flux is larger, the required filtration pressure difference is lower, and the advantages of energy saving and consumption reduction are obvious.
4. Titanium filter has good temperature resistance: the filter element of metal membrane is sintered at high temperature, the filter aperture does not change with the temperature, and the temperature resistance is excellent, which effectively ensures the stability of the filtration accuracy.
5. The titanium filter element has high strength and can run stably at stirring speed for a long time.
6. The titanium filter element has uniform aperture, slow flux attenuation, smooth surface, difficult to paste film, lower operation and maintenance cost.
7. The titanium filter element can be regenerated online or offline, which greatly extends the service life.
8. Tortuosity factor of filter element is small, pollution resistance is better, easier to clean and regenerate.
Filter Thickener Advantages - Membrane back-blowing and Cleaning
The new back-blowing concept to escort the filter element
Unique back blowing component design, professional and efficient.
Optimize the back-blowing process and operating parameters to improve the service life of filter element.
The regenerated liquid and pure water are cleaned to ensure the stable flux of filter element.
The frequency of cleaning and regeneration is small, the amount of acid is small, the concentration is only 0.5%-1%, the pickling operation is simple, the flux remains basically unchanged after cleaning, effectively reducing the waste of resources and waste acid treatment, the environmental benefits are obvious.
The unique off-line regeneration method improves the utilization rate of filter element and increases the service life of filter element.
Advantages of Filter Thickener - Structural Design
1.Integrated Design (5th Generation):
The reactor and thickener are combined into one, and the integrated design shorten the residence time outside the reactor,
improves product quality, saves space and reduces equipment investment.
2.Modular Skid Design:
The modular design of the pipeline system, the complex pipelines and instruments, control valves, etc. are integrated into
the skid-mounted, the manufacture and inspection of the skid are completed in the factory, and the overall transportation
and installation are completed, which ensures the installation quality of the products, improves the installation efficiency
on site, and is conducive to shortening the construction period.
3.Optimized Mixing Structure:
The mixing design is more reasonable, fully taking into account the actual situation in production, optimizing the blade
structure while ensuring the motor surplus, which can respond to various situations in production.
4.The Sealing Structure of the Filter Element and the Structure Arrangement of the Equipment were Optimized:
The installation and disassembly of the filter element is convenient, and the internal parts do not need to be lifted as a
whole, reducing the difficulty of installation and maintenance.
5.Optimization of Shell Structure for Filter Thickener:
Due to the large flux of the metal membrane, the thickener of the same specification uses less filtration area, so that the
equipment is optimized and the footprint is less;
6.The interior parts of the shell and the arrangement of the filter element are optimized:
Through structural adjustment, ensure the radar level meter installation channel and manual maintenance position, so that
the equipment installation and maintenance is convenient and fast, do not need to frequently open the upper head cover,
greatly reduce the difficulty of maintenance, the filter element can be quickly disassembled and installed, convenient
replacement and maintenance of the filter element;
7.Optimize the sealing structure and fixing of the filter element:
Prevent the displacement caused by long-term circular movement during the use of the filter element, and the
seal is more reliable.
Advantages of Filter Thickener - Intelligent Equipment
1. After large-scale long-term operation demonstration, the liquid level meter can accurately measure
the liquid level in the production process of the ternary precursor, which is convenient for liquid
level control
2. Automatic operation and control, easier operation
3. Control and Linkage:
The thickener level is interlocked with the concentrate outlet control valve to ensure the stability of the thickener level
The amount of clearing liquid is interlinked with the cleaning pipe regulating valve to ensure the stability of the amount of clearing liquid, so as to ensure the balance of the liquid level of the reactor and ensure the stability of production.
The amount of clear liquid should be equal to the amount of feed in the reactor, the data can be entered manually, and it can be automatically adjusted with the reactor level.
Mixing speed can be controlled
The cumulative calculation of reaction and working time
Blowback / backwash automation, to ensure long-term stable operation of the filter element
Each production data can be reflected in the control panel, and has a powerful communication function to communicate with the DCS in the central control room, control parameters can be displayed, adjusted and controlled in the central control room
Emergency stop control is set up, and abnormal stop is also protected in valve selection. For example, the valve connecting the compressed air and high pressure nitrogen pipeline is selected as a single acting control valve
Ensure that the valve is closed in time during shutdown, in order to avoid the continuous pressure of gas on the tank, resulting in safety hazards and waste of resources
