[0002] Scale inhibitors are a kind of agents that can disperse inorganic salts in water, prevent or interfere with the precipitation of inorganic salts on metal surfaces, and maintain good heat transfer of metal equipment. The application of scale inhibitors in wastewater treatment mainly reflects in preventing equipment scaling, increasing wastewater treatment efficiency, reducing energy consumption and carbon emissions, etc.
[0003] During the production and processing of scale inhibitors, the reaction solution in the reaction tank needs to be heated during the stirring process. During the reaction process, the acid-base degree of the reaction solution may fluctuate. In order to ensure the smooth progress of the reaction, it is necessary to add acidic or alkaline solution to the reaction solution in time to adjust the acid-base balance during the reaction. The existing adjustment method is to directly add the corresponding acidic or alkaline solution into the reaction tank according to the parameter data tested by the speed tester. Since the temperature of the reaction solution inside the reaction tank is relatively high, there is a temperature difference between the acidic or alkaline solution added into the reaction tank and the reaction solution, which may cause insufficient mixing of the acidic or alkaline solution and the reaction solution. Therefore, we propose a scale inhibitor production acid-base degree adjusting device. SUMMARY
