Description

Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology, specifically to a triethylamine hydrochloride wastewater pretreatment device. Background Technology

[0002] Triethylamine hydrochloride wastewater mainly contains triethylamine hydrochloride ((C2H5)3N·HCl), residual triethylamine (alkaline), chloride, etc. In order to pretreat the wastewater, pH adjustment and purification filtration are required, which is equivalent to purifying sodium chloride in high-salt wastewater before wastewater discharge.

[0003] Currently, wastewater pretreatment typically requires pre-filtration, but the filter structures are relatively simple and prone to clogging, making it difficult to clean and replace them. Furthermore, the wastewater is acidic, and the acidic environment can accelerate equipment corrosion. The pH of the wastewater needs to be adjusted during pretreatment, but existing equipment has a low rate of thorough mixing of the drugs and the aqueous solution, which affects the filtration effect and practicality of the equipment for wastewater pretreatment.

[0015] In the above technical solution, the lead screw is a bidirectional lead screw, which can drive the installation strip to move up and down reciprocally.

[0016] A further improvement of this utility model is that: guide rods are fixedly connected to the inner side of the purification box and to both sides of the lead screw, and the guide rods pass through the mounting strip and are slidably connected to it.
