It is a kind of simple in structure that the summary of the invention the purpose of this utility model is to provide, and high efficiency is easy to operate, simple and practical, cheap new type high temperature high pressure desorption electrolyzer.
The purpose of this utility model is to realize by following technical scheme:
A kind of new type high temperature high pressure desorption electrolyzer, its structural feature is: nucleus equipment is a high pressure tubular awl end electrolyzer, comprise cylindrical shell and loam cake that stripping liquid is housed, said cylindrical shell is provided with your liquid import and lean solution outlet, in said cylindrical shell, be provided with spaced negative plate and positive plate, said cylindrical shell bottom be a cone settling tank, and this cone settling tank bottom is that gold mud exports, and covers on said and is provided with the pressure air import that is communicated with pressure pump.During the utility model equipment work, in cylindrical shell, load onto earlier the stripping liquid for preparing, your liquid from your liquid import enters in the cylindrical shell under the effect of recycle pump, the charged work of spaced negative plate and positive plate, carrying golden charcoal separates out by carrying on the golden charcoal at gold ion under the stripping liquid effect, the gold ion of separating out obtains electronics and be deposited as golden molecule on negative plate is gold mud, and the positive and negative electrode conversion with negative plate and positive plate can make golden molecule come off and be stored in the cone settling tank.
Said cylindrical shell is the steel cylindrical shell, is lined with high temperature resistant, anti-highly basic, insulating liner in this cylindrical shell.
In said cylindrical shell outside the water level gauge that is connected with stripping liquid in the cylindrical shell is installed.
Said positive plate material is nonmetal electrical conductor, and said negative plate material is the charcoal fiber.
Said positive plate material is a stainless steel.
