One time saltwater calcium magnesium ion online titration analyzer

1、 Product Overview

In the production of chlor alkali industry, the quality of primary brine directly affects the efficiency, energy consumption, and service life of subsequent electrolysis processes. Among them, calcium (Ca ² ⁺) and magnesium (Mg ² ⁺) ions are the most important control indicators in saline water. Traditional laboratory manual sampling analysis has pain points such as strong lag, low frequency, and large human error, which are difficult to meet the real-time and precise control requirements of modern continuous production.

Shanghai Hegong Scientific Instrument Co., Ltd. has launched the ALT series specially designed for the chlor alkali industry, relying on years of deep technical accumulation in the field of automatic titrationOne time saltwater calcium magnesium ion online titration analyzerThe device adoptsThe chelation titration method (EDTA titration), combined with high-precision micro metering technology and intelligent endpoint determination algorithm, has achieved fully automatic, continuous, and real-time monitoring of trace calcium and magnesium ions in a saline solution, helping enterprises upgrade from "post inspection" to "process control" in intelligent manufacturing.

2、 Core working principle

This instrument is based on the classic ethylenediaminetetraacetic acid (EDTA) complexometric titration method and has been deeply optimized for the detection characteristics of low content calcium and magnesium ions in a saline solution

1. Automatic sampling and preprocessing: The system automatically draws saltwater samples from the production line pipeline through a built-in high-precision sampling pump, and undergoes preprocessing steps such as filtration and constant temperature to ensure sample representativeness.

2. Trace reagent addition: using HegongThe high-precision measuring tube technology (with an accuracy of up to 1 μ L) automatically adds buffer solution, masking agent, and indicator (or electrode system) to eliminate the influence of interfering ions.

3. Intelligent titration reaction: Automatic injection of EDTA standard titration solution, and real-time monitoring of potential changes (potentiometric method) or color changes (photometric/colorimetric method) during the reaction process by the system.

4. Precise endpoint determination: Built in intelligent algorithms automatically identify titration jump points, accurately calculate the total amount of calcium and magnesium ions, effectively avoid human judgment errors, and maintain high sensitivity even at extremely low concentrations.

5. Data output and feedback: The analysis results are displayed in real time and can be uploaded to the DCS/PLC system through signals such as RS485/Modbus. The dosing device is linked to achieve closed-loop control.

3、 Core advantages of the product

1. Detection accuracy and sensitivity

·Micro detection capability: specially designed for low content, it can accurately detect the total amount of calcium and magnesium ions at the ppm level, meeting the requirementsThe ion membrane caustic soda process has strict requirements for the quality of brine.

·Measurement technology: Using high-precision measuring tubes independently developed by Hegong, the titration volume control accuracy is highEnsure data reliability>99.7% during the micro titration process.

2. Minute level real-time response

·Efficient analysis cycle: A single complete analysis cycle only takes 3-10 minutes (can be set according to accuracy requirements), which can detect water quality fluctuations in a timely manner compared to the traditional laboratory's several hour lag.

·Continuous monitoring: supports 24-hour unmanned continuous operation, truly reflecting the trend of water quality changes during the production process.

3. Anti interference and adaptability of *

·Multimodal endpoint determination: integrating multiple endpoint determination modes such as potential method, color method, and photometric method, which can be flexibly selected according to on-site working conditions, effectively overcoming interference such as salt water turbidity and color changes.

·Adaptation to complex environments: Pipelines and contact components are made of corrosion-resistant materials (such as Teflon, high-purity ceramics, etc.) to adapt to highly corrosive saltwater environments and ensure long-term stable operation.

4. Intelligent and integrated design

·Multi function: A single device can be configured with multiple sampling channels to cyclically monitor multiple sampling points (such as different filter unit outlets), reducing equipment investment costs.

·Intelligent self diagnosis: equipped with functions such as reagent remaining monitoring, pipeline blockage alarm, automatic cleaning and maintenance, greatly reducing operation and maintenance workload.

·Seamless integration: Standard communication interface easily connects to the factory DCS/SIS system, providing critical data support for digital workshops.

4、 Application scenarios

·Chlor alkali chemical industry: a brine refining process for the production of ion exchange membrane caustic soda, monitoring the calcium and magnesium content in the inlet and outlet water of the chelating resin tower.

·Soda industry: the saltwater purification process in the production of ammonia alkali or combined alkali.

·Other high-purity water preparation: industrial water monitoring with strict hardness requirements.
