MAY-3070 automatic on-line concentration monitoring system

MAY-3070DMF Dry method on-line DMF solution monitor

Product application：

Dimethylformamide (DMF) is a widely used chemical raw material and an excellent solvent. In the production of PU leather, it is mainly used to dissolve resin and dilute slurry. DMF requires low moisture, and the content is generally above 99.9%. The quality and purity of DMF can be quickly detected by using the MAY-3070DMF concentration monitor, which has the characteristics of fast, convenient and high accuracy.

Application of Mayzum (MAYZum) -3070DMF Dry on-line DMF solution Monitor in exhaust gas neutralization DMF Below is a typical exhaust gas two-stage absorption neutralization device. In the dry production process of PU leather, the oven of the coating machine production line will produce high-temperature DMF waste gas, which is to use the strong absorption capacity of solvents (such as water) on the harmful or valuable components of DMF in the waste gas to purify the waste gas to meet the emission standards, or to recover valuable components, be distilled and purified for recycling, or to achieve two purposes of purification and recovery at the same time.

MAY-3070DMF dry method online DMF solution monitor, usually installed in the first cycle circuit, this section of the absorption solvent (such as water) from the second loop, the solvent has absorbed the target components in the second cycle loop, after further absorption in the first cycle loop, the absorption capacity of the solvent will be reduced. The MAY-3070DMF concentration meter can instantly monitor the concentration of the target component in the solvent, determine the absorption capacity of the solvent to the target component, and decide whether to increase the fresh absorption solvent to improve the absorption efficiency.

It is recommended that MAY-3070DMF be vertically installed in the circulation pump outlet in the form of bypass, vertically installed in the circulation pump outlet, 220AC\24V power supply is optional, 4-20mA, RS485, switching signal output is optional.
