Description

Technical Field

[0001] The present application relates to the technical field of chemical waste liquid, and in particular to a device for separating impurities from chemical waste liquid by stratification. Background Art

[0002] Chemical waste liquid refers to the wastewater produced in the process of producing products in chemical plants, such as oily wastewater from the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank areas, air separation and air compression stations, etc. After biochemical treatment, it can generally meet the national secondary emission standards. Due to the shortage of water resources, the water that meets the emission standards needs to be further deeply treated to meet the requirements of industrial water replenishment and reused.

[0003] The Chinese utility model with announcement number CN218774355U discloses a chemical waste liquid impurity stratification separation device, including a separation mechanism, a driving mechanism, a supporting mechanism and a control box, wherein the driving mechanism is located above the separation mechanism, the supporting mechanism is located below the separation mechanism, and the control box is located in front of the separation mechanism. A flow stabilizer and a balance float cover the liquid surface, which can effectively reduce the liquid surface shaking, and the installed extended grid can quickly calm the waves when the separation box shakes violently, thereby ensuring the stability of the layers inside the separation box and improving the separation effect.

[0004] Although the above technical solution can reduce the shaking of the liquid surface in the flow stabilizing plate and the balance float, when the internal pressure is too high, it will cause the water flow at the connecting port to be too fast. The fast water flow will remix the liquid at the stratification, thereby causing the waste liquid that has been stratified to be remixed. Utility Model Content
