Product description
Double stream mixed ion exchanger
1. Introduction
1.1. Purpose
The double flow mixed ion exchanger is an equipment for removing dissolved substances in water. Strong acid and strong alkali ion exchanger resins are installed in the exchanger. It is characterized by large output, which is generally twice as large as that of the mixed bed of the same specification.
Through the double flow mixed bed, the primary desalted water with conductivity less than 0.2us/cm and SiO2 ≤ 0.02mg/l can be obtained, which can be used as the make-up water for boilers above ultra-high pressure and once through boilers.
1.2. Model meaning
JHSL180•200
J -- Ion Exchange
H -------- mixed bed
SL -------- double flow
180 -------- equipment diameter (mm)
200 -------- resin layer height (mm)
1.3. Structural features
1.3.1. The upper water inlet device is in the form of cross porous pipe.
1.3.2. The alkali inlet device is in the form of main pipe and branch pipe.
1.3.3. The intermediate water outlet device adopts the form of external double main pipe and branch pipe inserted into the cylinder.
1.3.4. The lower water distribution device is in the form of porous plate and water cap.
1.3.5. The equipment is lined with 1751 semi hard rubber.
The equipment is equipped with local sampling device and inlet and outlet pressure gauges.
1.3.7. The pressure rating of all interface flanges is PN1.0MPa
1.3.8. The equipment can be equipped with manual lined diaphragm valve or pneumatic rubber lined butterfly valve.
