Description

Technical Field

[0001] The utility model belongs to the technical field of waste alkali solution neutralization, and in particular relates to a waste alkali neutralization treatment device with a monitoring function. Background Art

[0002] Waste alkali liquid treatment refers to the process of treating waste alkaline liquid to meet environmental emission standards or reuse requirements. The main sources of waste alkali liquid include wastewater, waste liquid and domestic sewage in industrial production processes. The common waste alkali liquid treatment method is neutralization. Neutralization method refers to reacting waste alkali liquid with acidic substances to neutralize it, thereby achieving a neutral or near-neutral treatment effect.

[0003] According to the utility model with authorization announcement number CN218981219U, a waste alkali liquid neutralization reaction tank is disclosed, including a tank body, a motor, a frame, a waste alkali liquid output end, and a neutralization liquid delivery pipe. The frame is located above the tank body, the waste alkali liquid output end is fixed to the top of one side of the tank body, the motor is fixed inside the bottom of the tank body, and the neutralization liquid delivery pipe is located above the frame.

[0004] Although the above technical solution adds turbine blades, which can stir the waste alkali liquid during the neutralization process and increase the neutralization rate, the above technical solution does not have the ability to monitor the internal waste alkali liquid in real time, and cannot accurately grasp the amount of acidic substances. Excessive or insufficient acidic substances will cause the waste alkali liquid to fail to meet the emission standards, thus requiring multiple neutralization adjustments, which not only increases the time for neutralization of the waste alkali liquid, but also reduces the use effect of the waste alkali liquid during the neutralization reaction. To this end, we provide a waste alkali neutralization treatment device with a monitoring function to solve the above problems. Utility Model Content
