Membrane Filter Press Application in Sugar Industry
The membrane filter press is a valuable equipment used in the sugar industry for various applications. It is an advanced filtration system that efficiently separates solids from liquids using a combination of pump feeder pressure and membrane plate technology.
In the sugar industry, the membrane filter press is commonly used for the clarification of sugar cane juice.
Introduction to the sugar industry
The revitalization of the sugar industry depends on science and technology. Filtration is an important link in sugar production. It is not only related to product quality, but also involves sugar loss and environmental protection during processing.
With the expansion of the production scale of sugarcane sugar factories in our country in recent years, the shortcomings of the current whole juice filtration process are gradually emerging. Therefore, filter presses are widely used in sugar production to filter mud juice and carbon juice. The efficiency of the membrane filter press is higher than other separation equipment; it not only increases the solid content of the filter mud but also reduces the residual sugar content in the filter mud.
Features of membrane filter press
Membrane Filter Press: The membrane filter chamber are formed by membrane filter plates and chamber filter plates, the feeding pump feed the sludge into the chamber and through ...
Fully automatic membrane filter press is an advanced filter equipment in the modern sugar industry, which fundamentally changes the passive situation of traditional filter press in sugar production and has received good results. This equipment uses imported polypropylene filter plates with extruded diaphragms, and uses PLC and frequency conversion control technology to realize fully automatic control of the entire filter press and process.
Polypropylene has good thermal stability and good heat insulation performance, and the filter plate is firm and flexible, ensuring the filter plate’s long-term service life. Compared with metal materials or rubber diaphragms, in the filtration of mud juice and carbon juice, polypropylene Filter plates have better corrosion resistance to various chemicals.
The use of advanced control and membrane pressing technology can improve the production efficiency of the whole machine, shorten the filtration time, reduce the sugar content of filter mud and increase the solid content of filter cake. By adopting the method of pressing the filter cake, the washing water scheme can be optimized, the amount of washing water can be reduced, and at the same time, the sugar content of the filter cake can be kept at a low level.
Pressing through the membrane can effectively reduce the moisture content of the filter cake and shorten the feeding time. The filter cake has been pressed and formed before the sludge is discharged, and the sludge discharge process can be successfully completed.
For a traditional semi-automatic filter press to unload sludge smoothly, it is necessary to increase the feeding time and pressure to fill the filter cavity with filter sludge and reduce water content. Only after the filter cavity is completely filled, air blowing and water washing can work, but carbon The filter cake of this method is easy to crack, which greatly limits the performance of washing water and air blowing. The semi-automatic filter press consumes a lot of time in the later stage of filtration, and the filtration efficiency is very low. In contrast, the membrane filter press can reduce the low-efficiency filtration time and achieve a higher solids content than the semi-automatic filter press.
The benefits of using a membrane filter press in a Sugar Factory
- The process effect is significantly improved. The thickening process can ensure the high efficiency and low sugar loss of the filter press, the sugar content of the filter mud can be controlled at about 0.5%, and the solid content can reach 70%;
- The environmental protection effect is obvious. The increase in the solid content of the filter mud not only reduces environmental pollution, but also directly provides raw materials that meet the production standards for the cement and other building material industries, and creates a new chain of resource reuse;
- A single device is highly efficient and automated High level, more suitable for the development needs of large sugar factories;
- Less consumption of filter cloth, low operating costs;
- Saving labor resources and reducing heat radiation.
