Measure Green Liquor Density (TTA) เครื่องวัดความเข้มข้นของน้ำยา

In - Line Process Refractometer แบ่งเป็นสองชิ้น ส่วนรับส่งสัญญาณแสง และส่วนอิเล็กทรอนิกส์ควบคุม
ให้การวัดค่าความเข้มข้นของน้ำยา Green Liquor อย่างต่อเนื่อง แปรผันตามดัชนีหักเหของแสงซึ่งสอดคล้องกับระดับความเข้มข้นของน้ำยา

การควบคุมน้ำยา Green Liquor ในอุตสาหกรรมเยื่อกระดาษและกระดาษ ที่ดีจะให้ผลต่อเนื่องถึงการควบคุมน้ำยาตลอดขั้นตอนการผลิต และเพิ่มประสิทธิภาพ ทำให้การควบคุมน้ำยาก่อนฉีดเข้าเตาเผาทำได้ง่ายขึ้น เลือกแสดงผลได้ทั้ง

Flanged Stanchion Directly In The Dissolving Tank

In the late 1970’s this is the first company to offer a complete Automatic Black Liquor Divert System specifically designed to protect the recovery boiler from a Smelt Water Explosion. Since then mills have installed this Process Refractometers all throughout the plant site: digesters, evaporators, concentrators, paper machines, and now the “Dissolving Tanks”.

A fully computerized In-Line Process Refractometer is a two-piece optical/electronic instrument that provides a continuous on-line measurement, in the most useful term. As many in the industry know, a Process Refractometer’s measurement principal is based on Refractive Index, which correlates well to the various different density measurements required in the Pulp & Paper Industry. In the case of the green liquor measurement, several concentration (density) ‘terms’ are available.

BENEFITS / FEATURES
Attractive Purchase Price
Installation is Simple
No Isolation Valve is used.
No High Pressure Pump Prism
Wash System is used.
Probe can easily, and quickly be removed, and re-installed at any time.
Maintenance is very Simple, and Minimal

Installation is Simple and Convenient:
The measurement is taken directly in the Dissolving Tank. A typical installation would use a Flanged Stanchion (Flanged Pipe Connection) through the floor directly above the Dissolving Tank to secure the Probe and submerge the Sensing Head Prism into the Green Liquor to a depth that achieves an accurate representative measurement. Because of this installation technique, and being atmospheric pressure, this installation allows for the safe removal of the Green Liquor Probe at any time without the need of any Isolation Valve.

Our superior designed wash nozzle utilizes 140 - 180 PSI (9 - 12 Bar) Steam to keep the sensing prism free of scale (coating) without the need for high-pressure pumps, and their associated high cost and frequent maintenance.

The unique design of the (Extra Long Probe) Sensing Head provides a safe, simple, and cost effective
measurement of Green Liquor Density directly in the Dissolving Tank. The XLP’s design is fully customizable to accommodate various lengths (8 – 10 Feet / 2.5 - 3 Meters is typical) and virtually any mounting flange or bolt pattern 6 inch (150 mm ID) or greater to accommodate existing mounting opportunities.
