2.1.2 Data recording and analysis: The technologist shall collect and register the daily data in the equipment, and regularly arrange professional technicians to analyze the data. By analyzing the data change trend, the technologist shall timely find out whether the process parameters deviate from the normal range, so as to take adjustment measures in advance.

3.Optimization parameter adjustment mechanism for waste caustic alkaline recovery system after aluminum extrusion dies etched

3.1 Establish the adjustment system: based on the monitoring of process parameters, establish the parameter adjustment system. When the parameters are abnormal, the system can automatically trigger the prompt adjustment mechanism to ensure that the process parameters are always stable in the best working range and ensure the stable operation of the system.

3.2 Manual intervention and review: Although there is an automatic regulation system, the possibility of failure cannot be completely ruled out. Therefore, it is necessary to arrange experienced operators to conduct regular inspection and manual review of key parameters. In case of failure or abnormality of automatic regulation, manual intervention should be carried out in time to manually adjust parameters, so as to avoid system operation failure caused by out-of-control parameters.

4.Raw material and material management for waste caustic alkaline recovery system after aluminum extrusion dies etched

4.1Strictly control the quality of raw materials

Screening of alkali liquor raw materials: When purchasing alkali liquor raw materials, cooperate with high-quality suppliers and require them to provide qualified and stable alkali liquor products. Sample and inspect the incoming alkali liquor in strict accordance with relevant standards, focusing on the key indicators such as purity and impurity content of alkali liquor, so as to prevent unqualified alkali liquor from entering the recovery system. So as not to affect the normal chemical reaction and long-term stable operation of the system.

4.2Standardize material flow operation

4.2.1 Precise metering and conveying: Precise metering equipment, such as flowmeter and weighing sensor, shall be provided for the addition and conveying of alkaline to ensure that the materials enter the corresponding position of the system accurately according to the set amount, so as to avoid reaction imbalance or other operation problems caused by the deviation of the amount of materials. At the same time, it is necessary to ensure that the material pipeline is unimpeded, and regularly check whether there is leakage or blockage in the pipeline, so as to ensure that the material can flow stably and orderly in the system.

4.2.2 Material storage management: spare alkaline and other materials shall be properly stored according to their chemical properties and storage requirements to prevent the quality of materials from being affected by dampness, deterioration and other reasons, and the principle of first-in first-out shall be followed when taking materials to ensure the stability and consistency of materials.

5.Personnel management and training of waste caustic alkaline recovery system after aluminum extrusion dies etched
