Description

Technical Field

[0001] The present utility model and this application relate to the technical field of waste liquid recovery, and in particular to an environment-friendly chemical waste liquid recovery device. Background Art

[0002] Chemical waste liquid refers to the wastewater produced during the production process of chemical plants, such as the oily wastewater from devices such as ethylene production, polyethylene production, rubber production, polyester production, methanol production, ethylene glycol production, oil product tank area, air separation and air compression station. At present, due to the shortage of water resources, the water that meets the discharge standard needs to be further deeply treated to meet the requirements of industrial make-up water for recycling. Since the impurities in the water are mainly suspended particles and fine hair fibers, using the mechanical filtration principle, microfiltration technology is adopted to remove the impurities. The working condition of the filter device is controlled by a PLC or a time relay to achieve automatic backwashing and automatic operation. The lift pump provides the required head for the filter, and the outlet water is directly introduced into the production system.

[0003] The existing patent CN216972218U proposes a chemical waste liquid recovery device. This patent can filter chemical waste liquid through a grid plate to filter the dregs in the water. Coupled with the coordinated use of the mounting seat and the fixing frame, the grid plate is very convenient to disassemble and assemble, and the staff can quickly replace the grid plate. However, since some toxic gases may be generated during the chemical waste liquid itself or during the chemical treatment, if directly discharged into the air without treatment, it will cause harm to the human body and pollute the environment. Therefore, the present utility model proposes an environment-friendly chemical waste liquid recovery device. Summary of the Utility Model
