Embodiment 1

[0030] Such as figure 1 As shown, this embodiment provides a complete set of high-salt industrial wastewater external circulation evaporation separation equipment, which includes a stock solution tank A1, a stock solution tank B3, an evaporator 6 and a condenser 17.

[0031] Specifically, the A feed channel 101 is connected to the stock solution tank A1, the discharge pipeline 102 of the stock solution tank A is connected to the feed pipeline 601 of the evaporator, and the first metering pump 2 is arranged on the discharge pipeline 102 of the stock solution tank A, and the stock solution The stock solution in the tank A1 is fed to the evaporator 6 through the first metering pump 2 and evaporated and concentrated in the evaporator 6 to form concentrated liquid and steam; the evaporator 6 is connected with the stock solution tank A1 through the circulation feed pipeline 103 of the stock solution tank A A mother liquid pump 7 is arranged on the circulation feeding pipeline 103 of...

Embodiment 2

[0050] refer to figure 1 , the stock solution enters the stock solution tank A1 and the stock solution tank B3; open the A feed channel 101, the stock solution in the stock solution tank A1 passes through the first metering pump 2 and feeds the evaporator 6 through the conductivity meter and the density meter; the stock solution is in the evaporator 6 Heating and evaporating, the separation chamber of the evaporator 6 intercepts the boiling solution and the liquid foam and droplets entrained in the steam, and the secondary steam enters the surface condenser 17; the concentrated liquid returns to the original liquid tank A1 through the mother liquid pump 7 and the electromagnetic valve a103; When the raw material solution in the raw liquid tank A1 passes through the pipeline where the conductivity meter and the density meter are located, and the raw material liquid reaches the set solution concentration or salt content, the first metering pump 2, solenoid valve a101, solenoid va...

Abstract

The embodiment of the invention discloses complete equipment for external circulation, evaporation, and separation of high-salt industrial wastewater, which comprises a stock solution tank A, a stocksolution tank B, an evaporator and a condenser, wherein an A feed channel is connected with the stock solution tank A, the stock solution tank A is connected with the evaporator through the dischargepipe of the stock solution tank A, and the discharge pipe of the stock solution tank A is provided with a first metering pump; the evaporator and the stock solution tank A are connected through the circulating feed pipe of the stock solution tank A; a B feed channel is connected with the stock solution tank B, the stock solution tank B is connected with the evaporator through the discharge pipe ofthe stock solution tank B, and a second metering pump is arranged on the discharge pipe of the stock solution tank B; the evaporator and the stock solution tank B are connected through the circulating feed pipe of the stock solution tank B. The complete equipment for external circulation, evaporation and separation of the high-salt industrial wastewater provided by the embodiment of the inventionis reasonable in structure and simple in operation, and can effectively improve the concentration ratio in the heating and evaporation of the high-salt wastewater, thereby significantly improving thetreatment effect of the high-salt wastewater, and being high in safety.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of high-salt wastewater treatment, in particular to a complete set of equipment for external circulation evaporation and separation of high-salt industrial wastewater. Background technique [0002] High-salt wastewater usually refers to industrial organic wastewater with a total dissolved solids (TDS) content higher than 1%, which is commonly found in chemical, pharmaceutical, oil and gas, and seafood processing industries. At present, high-salt wastewater treatment technologies include electroplating, ion exchange, membrane separation, heating evaporation, oxidation and other processes. In the hazardous waste disposal industry, process disposal effluent has complex components, high salinity, and variable water quality. After centralized disposal of production wastewater in the factory area, the sewage usually requires further advanced treatment in order to meet discharge standards ...
