Floating bed sodium ion exchange equipment is a kind of counter-current regeneration soft water treatment equipment. The source water is discharged from the bottom to the upper part, and the regenerated liquid is discharged from the upper part and discharged from the bottom. In general, the salt content in the source water is 500 mg l when the flow rate is high. When the source water contains salinity at 500 mgl, it can be operated in series with other ion exchangers or reverse osmosis equipment. This equipment has a high flow rate and a large output, but the structure of the equipment is complex and the resin requirements are strict.
1. The structure of the floating bed sodium ion exchanger is shown in the following figure:
2. Introduction to the internal structure of the floating bed sodium ion exchanger:
1. The water inlet device is a dome-shaped perforated plate water cap type.
2. The water outlet device is a perforated plate water cap type.
Description: 1. The equipment is equipped with a local sampling device and an inlet and outlet pressure gauge.
2. The pressure level of all interface flanges is 1MPa.
3. The equipment can be equipped with manual rubber diaphragm valve and pneumatic rubber lining valve, 4. The regenerated liquid of the equipment is hydrochloric acid, sulfuric acid and sodium hydroxide.
5. The valve at the resin loading and unloading port is a DC rubber-lined diaphragm valve.
6. When the diameter of the equipment is DN 1250, the multi-well plate adopts ** blue knot.
7. The equipment is lined with 1751 semi-hard rubber.
8. This equipment is designed according to strong resin, if the user uses weak resin to operate, it must be indicated when ordering.
9. Add 200mm grease filler to the resin layer of the equipment
Floating bed sodium ion exchange equipment is a kind of efficient counter-current regeneration soft water treatment equipment. The principle of operation is very simple and ingenious: the source water flows from the bottom into the upper part of the plant, the reclaimed liquid is discharged from the upper part, and the waste water flows from the bottom. Through this circular flow, the salts in the source water are successfully removed, making the water purer and clearer.
This device works very well under certain conditions. In general, when the salt content in the source water is low and the flow rate is high, a floating bed sodium ion exchange device is sufficient. As long as the salt content of the source water does not exceed 500 mg l. However, when the salinity of the source water is higher than 500 mg L, it can be considered to run in tandem with other ion exchangers or reverse osmosis equipment to solve the salt removal challenge.
