Description
Technical Field
The utility model relates to an electric heating concentration device used in a copper electrolysis liquid purification process, in particular to an electric heating concentration tank.
Background
The electrothermal concentrator is one of the important devices in the wet smelting liquid-cleaning process, especially in the copper electrolysis liquid-cleaning process, and is characterized by that it utilizes the heat effect produced when the current is passed through the acidic conductive liquid to heat the solution, so that it can be evaporated and concentrated, and can be crystallized, filtered and can obtain the final product copper sulfate. The optimum heating temperature for evaporative concentration is 170 deg.C, but at this high temperature the SO in the electrolyte is present4 2-Has extremely strong corrosivity, and lead must be lined on the groove wall and the groove bottom of the electrolytic tank for containing the electrolyte to resistHigh temperature SO4 2-Corrosion of (2). Because of its high density and low hardness, lead must line the steel envelope to develop its corrosion resistance characteristics.
The traditional electric heating concentration tank is composed of an acid-resistant tile layer, a lead plate layer and a steel plate shell layer from inside to outside, and a lead plate is fixed on a steel plate in a lead-lined mode. The method is characterized in that a lead strip is melted by oxygen-hydrogen flame and then attached to the surface of a lined object (or) equipment to form a compact lead layer with a certain thickness, the anticorrosion means is called lead lining, the surface of the treated equipment is brushed with a layer of welding flux, then heated by gas welding, coated with a layer of flux water when the temperature reaches 320-350 ℃, and if the flux layer formed on the surface presents moist luster, the welding rod is melted. The flame moves forward against the molten lead and the molten lead is welded to the surface of the equipment. In the field, the lead plate is fixed by adopting a lead lining fixed block structure, the lead plate and the lining block are arranged according to a rhombus rule, and finally, the lead plate and the lining block are subjected to plug welding and are polished to be flat. The installation of the concentrating tank at the production site is a slow building process: firstly, after the outer layer of the steel structure is welded and installed, the connection between the lead plate and the steel plate is completed by adopting a lead-lined fixed block mode; acid-resistant daub is smeared between the inner layer of the lead plate and the acid-resistant ceramic tile on the outermost layer, and the connection between the inner layer of the lead plate and the acid-resistant ceramic tile on the outermost layer is completed by means of the tight adhesion of the acid-resistant daub; laying three layers of acid-resistant ceramic tiles, and adhering the layers by acid-resistant cement paste; and after all the daub is shaped and dried, injecting the electrolyte into a concentration tank to start production, wherein about 2 months are needed before and after building and installing time.
The connection between the middle lead plate layer and the outer steel plate depends on the welding position of each diamond lead-lined fixed block and the steel plate and the connection between the middle lead plate layer and the outer steel plate and the acid-resistant ceramic tile depends on the bonding of the acid-resistant daub, and the temperature of the copper sulfate electrolyte in the electric heating concentration tank is kept at a high temperature of about 170 ℃ for a long time. However, when the temperature of the electrolyte needs to be reduced under special conditions, particularly during the period of shutdown and maintenance, the temperature of the electrolyte is reduced to room temperature, each structural layer in the electrolytic cell, namely the acid-resistant tile layer, the daub layer, the lead plate layer and the steel plate layer, generates stress due to thermal expansion and cold contraction, the lead plate layer and the steel plate layer generate relative movement due to different stresses of the structural layers, the lead plate is torn by the fixing mode of the lead lining block, and once a leak point or damage occurs on the lead plate, the whole electrolytic concentration cell is scrapped due to continuous corrosion, so that the corrosion prevention effect is lost.
Meanwhile, because the stress of the daub layer is different from that of the lead plate layer and the acid-resistant tile layer, gaps can be generated among the structural layers, highly corrosive electrolyte can quickly permeate into the lead plate layer to be in direct contact with the lead plate layer, and the lead plate is in high-temperature SO for a long time4 2-The corrosion prevention effect is greatly reduced. Once the concentrating tank is scrapped due to corrosion, the reinstallation needs a long bricking period, and the production efficiency is seriously influenced.
Chinese patent document CN201120051978.2 discloses an electrothermal concentration tank, which effectively increases the corrosion resistance by adding an asbestos layer. But at the bottom of the concentration tank, because of bearing huge gravity for a long time, the acid-resistant tile layer generates stress and is dragged between the asbestos layer bonded with the acid-resistant daub in the process of thermal expansion, and the long-time use easily causes the cracking of the asbestos layer and the acid-resistant daub, SO that the whole structure can resist high-temperature SO4 2-The erosion resistance of (a) is reduced.
