Abstract

The invention discloses an electroplating wastewater filtering device. The device comprises a condensing tower, a filter box mounted at the bottom, a reaction bin mounted on the right side and an output pipe connected to the right side, the condensing tower comprises a liquid inlet formed in the top; a spiral guide pipe arranged inside; a constant-temperature tank mounted on the inner side of the spiral conduit; an external conduit mounted on the constant-temperature tank; a connecting ring mounted on the outer side of the spiral conduit; a metal wire arranged in the spiral guide pipe; a lifting rope connected above the metal wire, and a crystal nucleus arranged on the metal wire. The device is provided with a condensing tower; circulating low-temperature liquid is introduced into the constant-temperature tank, so that the interior of the condensing tower is kept in a low-temperature state; then the wastewater is guided into the spiral guide pipe from the liquid inlet, soluble substances are condensed, separated out and attached to the surface of a crystal nucleus due to temperature reduction, and crystal particles fall off after growing relatively large, so that the concentration of pollutants in the low-temperature wastewater is reduced, the precipitates are filtered by the filter box and remained on the filter plate, and the wastewater enters the reaction bin for subsequent treatment, so that the reaction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electroplating wastewater filtration, in particular to an electroplating wastewater filtration device. Background technique [0002] The sources of electroplating wastewater generally include scouring the floor of the workshop, scrubbing plate washing water, condensate water from ventilation equipment, and various bath liquids and drainage caused by "running, dripping, dripping, and leaking" due to leakage of plating tanks or improper operation and management; The cooling water of the equipment, the cooling water is not polluted except for the temperature rise during use. The water quality and quantity of electroplating wastewater are related to the process conditions of electroplating production, production load, operation management and water use methods and other factors. The water quality of electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions...
