Problems solved by technology

[0005] Compared with the tube-and-tube evaporator, the plate evaporator is easy to clean and has high heat exchange efficiency, but the device has problems such as circulating water pollution and large steam consumption, especially for small and medium-sized copper smelting enterprises that have no waste heat recovery or difficult steam sources. High cost and direct discharge of circulating water polluted by copper sulfate are still the main obstacles restricting the application

Embodiment Construction

[0027] In conjunction with the accompanying drawings, the description is as follows:

[0028] The method of the present invention comprises:

[0029] (1) Inlet control

[0030] The copper sulfate raw liquid enters the first-effect evaporation separation tank through the centrifugal pump driven by the frequency conversion motor and the feed pipe. When the limit liquid level is reached, the liquid inlet pump stops running, and no longer sends liquid to the first-effect evaporation separation tank;

[0031] (2) Drainage control

[0032] Drainage of the first-effect evaporation separation tank: When the density meter installed in the lower half of the separation tank detects that the concentration reaches the set density, the drain valve opens to send liquid to the second-effect separation tank, and when the liquid level gauge on the top of the second-effect separation tank When it is detected that the liquid level reaches the set level, the liquid discharge valve is closed, ...

Abstract

The invention discloses an automatic feeding and discharging control method of a copper sulfate vacuum evaporator. The method comprises the following steps: liquid feeding control, liquid discharging control, and safe operation of device. Through the control method, the copper sulfate evaporating effect is improved, the steam using amount is reduced by 50%, moreover, the circulating water in the device is pollution-free, and the method has the advantages of reliability and convenient operation.

Description

[0001] technical field [0002] The invention relates to a method for realizing automatic feeding and automatic discharging control device on the vacuum evaporation system that removes impurities after evaporating and concentrating the waste electrolyte to purify the electrolyte, and belongs to the hydrometallurgy of non-ferrous metals copper, nickel and cobalt A kind of craft. Background technique [0003] In 1985, Guixi Smelter imported a complete set of copper electrolytic refining technology and key equipment from Japan's Sumitomo Metal Co., Ltd., among which the vacuum evaporation is a tube-and-tube siphon self-circulation evaporation device, which is provided by Japan and manufactured by itself in China. The disadvantage is that the material is fouled. Afterwards, it is difficult to clean, resulting in a rapid decrease in evaporation rate and an increase in steam consumption. The cleaning cycle is less than 3 months, and the entire 5-meter-long heat exchange tube must ...
