Ceramic vacuum filters have demonstrated significant advantages in the field of industrial solid-liquid separation due to their high efficiency, energy saving, and environmental friendliness. The core advantages include high vacuum degree, low energy consumption, low cake moisture content, and long service life.
Overall, the main advantages of this device are reflected in the following aspects:
High vacuum degree, high filtration efficiency
The ceramic vacuum filter can achieve a high vacuum degree of -0.09 to -0.098 MPa, which is much higher than traditional equipment. This is thanks to its use of microporous ceramic plates, which utilize capillary effects to achieve "water flow without ventilation", greatly reducing vacuum losses and maintaining a stable and efficient filtration process.
Extremely low energy consumption and significant cost savings in operation
Compared with traditional vacuum filters, the energy consumption of ceramic vacuum filters is only 10% to 20%, and the energy-saving effect can reach over 80%. For example, a device can save over 100000 kWh of electricity annually, directly saving hundreds of thousands of yuan in electricity bills. It only needs to be equipped with a low-power vacuum pump (0.8~3kW) to meet high vacuum requirements.
Low moisture content in filter cake improves material quality
After filtration, the moisture content of the filter cake can be reduced by 2% to 4%, and in some scenarios, the moisture content of the concentrate can be reduced from 18% to 8%, significantly improving transportation and subsequent processing conditions, while reducing energy consumption in the drying process.
The filtrate is clear and recyclable
The solid content of the filtrate can be as low as less than 50ppm, and even reach 0.003% to 0.004%. The water quality is clear and transparent, and can be directly reused in the production system, achieving water resource recycling, reducing emissions, and outstanding environmental benefits.
High degree of automation and easy maintenance
The equipment adopts PLC fully automatic control, which runs stably and reliably, with a utilization rate of over 95%. No need for filter cloth, avoiding the losses and labor costs caused by frequent replacement, low labor intensity for workers, and easy maintenance.
Wide applicability and strong stability
Suitable for multiple industries such as mining, metallurgy, chemical engineering, environmental protection, and food, especially adept at handling fine and viscous materials such as concentrates, tailings, and sludge. Ceramic plates are corrosion-resistant, high-temperature resistant, and have a long service life. Some manufacturers' equipment can operate continuously for 3 years without failure.
Combining economic and environmental benefits
Although the initial investment is relatively high, the investment payback period is short due to its energy-saving, water-saving, and low maintenance costs. For example, a copper mining enterprise saved over 2 million yuan in drying costs annually, and a tailings processing project saved 1.63 million yuan in electricity costs annually.
