4,Excellent operating environment, the environmental protection index.
5,Can provide a full range of design and non-standard equipment supply, and is responsible for the installation supervision, personnel training, debugging to mark one year free service.
Introduction of production line
The production of copper sulphate pentahydrate equipment connection diagram:
2,Production technology introduction:
Raw material: purple miscellaneous copper, wire, sheet, block, powder, etc.), sulfuric acid industrial grade, industrial water, C1 - content & le: 30 mg/L; Cooling water has no special requirements.
(2)Copper material selection process
Copper material to sorting, eliminate iron, aluminum and other visible metal, bare copper wire can not burn, enameled wire can be used only by the burning.
(3)Dissolve copper process:
Soluble copper liquid from the mother liquor before preparation of sulfuric acid, water, and soluble copper in micro bubble dissolved copper kettle, soluble copper temperature around 85-90 ℃. Liquid after dissolved copper (copper about 180 g/L, the proportion of 1.38 to 1.42) into the settler.
Microbubble faintly soluble copper kettle self-provided float drainage component and swirl solid-liquid separation, sedimentation process of setting up the settler a further separation and water separation of content into the liquid pool, after impurities removal solution into the mother liquid pool.
After settling process of cleaning solution in the crystallization process.
Copper sulfate crystallization in rotary force completed the crystallization machine, cold water is provided by the cooling tower system, used in cooling water circulation. After the crystallization process of copper sulphate product in 1-4 mm particles precipitate from the solution, the crystal slurry (+ crystal mother liquor), the temperature can drop to near room temperature, crystallization rate generally about 70%. Crystal slurry into the thick device for a preliminary solid-liquid separation, mother liquor back in mother liquid pool, crystal after accumulated to a certain amount into the washing drying processes.
(6)Washing drying processes:
Crystal slurry by the thick bottom valve in a centrifugal filter, the liquid - water washing off - weighing packaging after dry.
1.Monomer can be run, do not need other air compressor, boiler and other supporting facilities
2.High efficiency, since the heat run, atmospheric pressure equipment
3.Less land needed
4.Automatic oil removal, etc
5.Occupy less raw material quantity, occupy less money
7.Can provide one year free technical support in the contract
Soluble copper kettle technology introduction
Chemical stability due to copper, copper in non oxidizing acid dissolution is very difficult, plus oxidant is currently accepted method of dissolved copper. Soluble copper kettle in the process of practice is in dilute sulphuric acid soluble copper equipment such as zhongtong into the air (the most cheap oxidant) to realize the copper dissolved.
It is generally believed that copper dissolved in the general air of acid typical electrochemical reaction process, access to adequate air oxidation potential of the guarantee solution should be able to make the reaction smoothly, but in fact use "neutralizing tank" dissolve copper is still slow (dissolution rate is generally 2 kg per cubic meters per hour). We believe that in addition to the electrochemical process, should have other process, such as the surface of the copper oxidation by air directly into copper oxide, and copper oxide reaction with acid. Copper surface is easily oxidized in the air, son copper oxide and acid reaction is typical of acid-base reaction, so as long as you provide better conditions for the surface oxidation of copper, soluble copper speed, which may be greatly improved. Micro bubble soluble copper kettle is based on the above ideas through a large number of experiments successfully developed a new soluble copper equipment, the key measure is to pass into the air in the form of micro bubbles of neutralizing tank mixed with acid emulsion, micro bubbles and copper materials have a good contact with the opportunity, oxidation speed increase, making equipment.
Because microbubble dissolved copper kettle oxidant at work (air) utilization rate can reach more than 30%, so no longer need to pass into excess air, thereby reducing the reaction heat loss, timely in low acidity of sulfuric acid (< 30 g/l), under the condition of the micro bubble soluble copper kettle can still achieve the thermal response, and even the hot start. At the same time due to the smaller ventilation in micro bubble surface covered, make out the reaction of the exhaust gas greatly improved environmental indicators.
Micro bubble dissolved copper used to dissolve copper, in the leaching of a variety of alloy has good use prospect. Practice has proved that the micro bubble soluble copper kettle in copper - nickel, copper, cobalt, copper and tin alloy, such as leaching has also made gratifying progress. Micro bubble solution technology of copper hydrometallurgy comprehensive recycling provides a new process route and equipment selection.
Micro bubble soluble copper kettle as a kind of solid liquid gas three phase reaction equipment, physical size of solid materials has good adaptability, depending on the size of the material (block, piece, silk, grain, powder) respectively in fixed bed, half fixed bed, fluidized bed form work, has the certain universality.
Equipment main technical and economic indicators
