Fully-automatic and continuous chemical nickel liquid waste treatment system

Abstract

The invention provides a fully-automatic and continuous chemical nickel liquid waste treatment system. The fully-automatic and continuous chemical nickel liquid waste treatment system is characterized in that the chemical nickel liquid waste treatment system can conduct solid-liquid separation on chemical nickel liquid waste and comprises evaporation equipment, a cooling tower, heat conduction oil circulation equipment and an automated control unit; the evaporation equipment comprises a vapor-liquid separator, a feeding electric valve, an emptying valve, a first heating chamber, a second heating chamber, concentrated liquid discharge valves, a condenser, a water storage tank and a vacuum pump; in the work state, the first heating chamber and the second heating chamber work by turns and do not work simultaneously; the water storage tank is composed of a first tank body and a second tank body; the heat conduction oil circulation equipment comprises a heating groove and a heat conduction oil circulation pump; the automated control unit comprises a heat conduction oil heating control module, a temperature sensor, a feeding control module, a first sensor, a condensate water discharging control module and a second sensor. By means of the chemical nickel liquid waste treatment system, phosphorus, nickel and COD in chemical nickel liquid waste can be effectively removed.

Description

technical field [0001] The invention relates to the field of industrial waste liquid treatment, in particular to a fully automatic and continuous chemical nickel waste liquid treatment system, which is especially used for treating chemical nickel waste liquid produced in circuit board processing industry and electroplating industry. Background technique [0002] Electroless nickel surface treatment is widely used in circuit board industry and electroplating industry. In the production process, because the chemical nickel stock solution has been left for a long time and cannot meet the production requirements due to chemical reactions, it is discarded (commonly known as aging). . The concentration of pollutants in these two waste liquids is high, the risk factor is high, and the treatment is difficult. These two waste liquids all contain a certain amount of nickel, but the nickel content is low and has no resource utilization value; the main components of the chemical nicke...
