Quantitative dosing device for papermaking wastewater

Core functions of quantitative dosing device for papermaking wastewater

Accurate dosing: Automatically dosing agents (such as coagulants, defoamers, etc.) according to preset doses to ensure stable treatment effects. ‌

Strong adaptability: can quickly respond to water quality fluctuations and reduce environmental pressure on enterprises. ‌

Typical application scenarios

Paper wastewater treatment: For high COD, suspended solids and other pollutants, efficient degradation is achieved through a three box dosing device (including solution tank, metering pump, and control system). ‌

Industrial water treatment: such as circulating cooling water systems, industrial park wastewater, etc., require customized configuration of chemical types and dosing parameters. ‌

Technical Features

Automation control: Integrated PLC system, supporting real-time monitoring (such as pH, COD) and dynamic feedback adjustment. ‌

High precision metering: The precision of the metering pump can reach ± 1%, with a flow range of 1L/h to 8000L/h and a pressure of 0.1MPa to 25MPa. ‌

advantage

Improve processing efficiency: reduce manual operations and minimize drug waste. ‌

Green and environmentally friendly: helping the paper industry achieve sustainable development. ‌

Quantitative dosing device for papermaking wastewaterThe stability of the drug is mainly affected by factors such as drug characteristics, equipment materials, and environmental interference. Here are the key points:

Drug characteristic adaptation

Papermaking wastewater contains high concentrations of cellulose, lignin, and suspended solids, and it is necessary to choose materials that are corrosion-resistant and anti clogging. PTFE fluoroplastic or stainless steel material metering pumps and pipelines can reduce scaling and avoid data fluctuations caused by flow meter blockage. ‌

Anti interference design

Electromagnetic shielding: Adopting a double-layer metal shell and differential signal transmission, it can resist electromagnetic interference from motors or high-frequency equipment, and the data fluctuation amplitude can be reduced to ± 0.5%. ‌

Bubble separation: For media containing bubbles (such as bleach), a bubble separation device should be equipped to prevent bubbles from interfering with flow measurement. ‌

Temperature and pressure compensation

The temperature changes greatly in the papermaking process, and a built-in temperature sensor is required to correct the flow data in real time. The pressure compensation function can cope with pipeline pressure fluctuations and ensure dosing accuracy.
