- Design Parameters
The u-fc-j series candle filter can automatically regenerate the filter elements without stopping the system. It is a full-automatic self-cleaning filter, which can effectively reduce manual cleaning without replacing the filter elements. It is widely used in continuous operation, high-risk operation environment and occasions where ordinary metal filter elements are not suitable.
Performance features:
working principle:
When the liquid passes through the filter, the particle impurities are blocked on the outer surface of the filter element, accumulating to form a filter cake, which gradually increases the pressure difference between the inlet and outlet of the filter. When the pressure difference reaches a default value (150kPa), it means that the filter cake reaches a certain thickness, at this time, the filterable flow of the filter element becomes smaller and smaller, the controller starts the backwash action, and the liquid reverses from the inside to the outside of the filter element Flow, take away the impurities on the surface, use the reverse flow of filter fluid to wash the filter cake on the outer surface of the filter element. When backwashing, the controller switches over a group of valves of the filter to be backwashed, that is, close its inlet valve, then open the drain valve, a part of the liquid of the filter fluid flows reversely to backwash the filter, quickly remove the filter cake on the surface of the filter element, and discharge the residual liquid into the sewage collection pipeline, Then close the drain valve, open the inlet valve, and return to the normal filtering state.
Main scope of application:
Applicable industries: petrochemical, beverage, fine chemical industry, grease, water treatment, titanium dioxide, power, polysilicon, etc;
Applicable fluids: resin, regenerated wax, cutting oil, fuel oil, lubricating oil, mechanical cooling oil, transformer oil, bone glue, gelatin, citric acid, syrup, beer, epoxy resin, polyglycol, etc;
Working process:
Effect of Riser:
In the case of the new type of u-fc-j candle filter, the compressed air penetrates through the cake layer, so that the liquid in the cake penetrates into the candle tube. Together with the residual filtrate in the candle tube, it rises through the liquid lifting tube, and then exits the filter. Therefore, the filter cake from the top to the bottom of the candle tube can be evenly filtered out.
Other circular candle tube filters do not have a lifting pipe, so the compressed air passing through the cake layer will drain from the upper part, and the filter cake at the lower part will mix into the residual filtrate and drain. Therefore, it is impossible to filter and discharge the filter cake.
U-fc-j new pulse filter, put in more backwash liquid than the capacity of the riser, and then quickly send compressed air to the riser. The backwash liquid will rise to the upper part of the filter element due to the effect of air pressure rise, so as to effectively backwash. (when the filter cake is filtered and discharged, the filter cloth changes greatly due to the shape of liquid lifting pipe and special candle pipe, so the filter cake is effectively discharged.).
For other filters without riser, even if backwashing liquid is put into the filter element, it cannot be injected into the upper part of the filter element. After that, even if the compressed air is fed, the lower part of the filter element can only be cleaned. Moreover, the compressed air will gradually drain from the upper part, and the better backwashing effect will not be obtained.
Performance features:
1. A completely closed high safety system without rotating mechanical parts (except for pump and valve);
2. Automatic filtering;
3. Simple and modular filter elements;
4. The design of mobility and flexibility meets the requirements of short production cycle and frequent batch production;
5. The sterile filter cake can be discharged into the sterile container in the form of dry slag, slurry and re beating;
6. The patented spray washing system can greatly save the consumption of washing liquid;
7. Patented follow volume filtration enables almost 100% recovery of solid and liquid, thus ensuring the integrity of batch filtration;
8. CIP cleaning can be easily realized, and all parts can be disassembled for inspection and inspection;
9. Simple filter cake washing, drying and unloading;
10. Carry out SIP sterilization step by step by steam or chemical method;
11. The filter cloth is completely matched with the product property;
12. It can be used in the production of free granule injection;
13. All sanitary fittings are sealed with O-ring to meet GMP flange requirements;
14. Equipped with sterile pump and instrument.
