Description
Technical field
The utility model relates to the horizontal reacting still, particularly the wall-retaining structure of horizontal reacting still.
Background technology
It is reactor that zinc concentrate oxygen is pressed the capital equipment that leaches, and it generally is operated under strong acid solution, pure oxygen, high temperature and the certain pressure, so the equipment structure has certain particularity.Reactor generally adopts horizontal retort, and the still cross section is cylindrical, by outer and in be respectively the shell steel plate, ward off lead layer (about 6～7mm is thick), the two-layer acid-resistant thermotolerant ceramic brick of liner (the about 230mm of total thickness); Reactor is interior to be five service depots that are interconnected along the still longitudinal subdivision, and each service depot is separated by barricade, and independently stirring system, heating (and cooling) system and logical oxygen system are respectively arranged.Aborning, ore pulp is added by successive first service depot in reactor, enters next service depot through the barricade overflow, discharges to the 5th service depot.Each service depot's upper gas intercommunication, each service depot feeds the oxygen of controlled rate separately, provides oxidizing atmosphere to the ore pulp that stirs, and is full of in reactor under the atmosphere of oxygen, and zinc concentrate is leached in waste electrolyte.
Barricade project organization in the tradition reactor generally has two kinds: a kind of is that steel plate is warded off plumbous rear perimeter edge lining brick barricade, and another kind is to adopt pure titanium plate to do barricade.Production practices for many years prove that these two kinds of structures all have tangible weak point in the actual production use.
Adopt the structure mode of occupation in practice of " steel plate is warded off plumbous rear perimeter edge lining brick barricade " to be: in the time of 20 ℃～100 ℃, the coefficient of thermal expansion of 16MnR steel plate and acid-resistant thermotolerant ceramic brick is respectively 12 x 10
-6Mm/mm/0 ℃ and 4 x 10
-6Mm/mm/0 ℃, the coefficient of thermal expansion of acid-resistant thermotolerant ceramic brick is more much smaller than 16MnR steel plate, when so reactor heats up since the thermal deformation of steel plate greater than acid-resistant thermotolerant ceramic brick, acid-resistant thermotolerant ceramic brick and clay that the steel plate periphery is built by laying bricks or stones are subjected to the thermal stress that stretches, long this operation causes middle part brick large tracts of land breaking releasing, the barricade sideway stance brick of barricade to produce serious crack, peeling, damaged situation such as peels off, ward off the leaded steel plate in the middle of exposing, cause barricade destroyed, often need repairing.
Adopt the structure mode of occupation in practice of " pure titanium plate is done barricade " to be: in the pressure leaching process of zinc concentrate, once to attempt many materials and prevent corrosion.The acid-resistant corrosion of titanium material is very strong,, long service life good because of titanium material antiseptic property, light, the good ratio of performance to price is arranged, so the titanium material is a preferred material.But because the burning easily in oxygen atmosphere of titanium material, and when zinc concentrate pressure leaches, must use pure oxygen, therefore because the control of the feeding amount of oxygen is improper, the situation of titanium material burning happens occasionally in the reactor.How preventing the burning of titanium material, is a major issue guaranteeing the reactor safe operation.
Along with the zinc concentrate wet method smelting process in the wideling popularize and using of China, safety, reliability and convenience that reactor uses are had higher requirement.

What the both sides of this barricade were provided with protrusion builds the deflected current wall that forms by laying bricks or stones by acid-resistant thermotolerant ceramic brick.
Through hole is offered in the bottom of this barricade and deflected current wall junction.
Special-shaped acid-resistant thermotolerant ceramic brick is adopted in this barricade and deflected current wall and reactor kettle brick lining junction, and it is the square of interior concave arc that the cross section of this abnormity acid-resistant thermotolerant ceramic brick is one jiao, makes this barricade, deflected current wall and reactor kettle brick lining junction form circular-arc.
The contact surface of this acid-resistant thermotolerant ceramic brick and ore pulp is the light face, and all the other each faces all are hair side.
The acid-resistant thermotolerant ceramic brick of this barricade and deflected current wall " cross " is alternately arranged, i.e. cross arrangement anyhow; The special-shaped acid-resistant thermotolerant ceramic brick that this barricade and deflected current wall are connected with reactor kettle brick lining partly embeds between the internal layer brick of kettle brick lining internal layer.
Compared with prior art, the beneficial effects of the utility model are: the utility model barricade all adopts acid-resistant thermotolerant ceramic brick to build by laying bricks or stones, and set up deflected current wall, through hole is offered in bottom in barricade and deflected current wall junction, and adopt special-shaped acid-resistant thermotolerant ceramic brick in barricade and deflected current wall and reactor kettle brick lining junction, it is the square of interior concave arc that the cross section of this abnormity acid-resistant thermotolerant ceramic brick is one jiao, so just make barricade, deflected current wall and reactor kettle brick lining junction form circular-arc, and when building by laying bricks or stones, the acid-resistant thermotolerant ceramic brick of this barricade and deflected current wall " cross " is alternately arranged, i.e. cross arrangement anyhow; The special-shaped acid-resistant thermotolerant ceramic brick that this barricade and deflected current wall are connected with reactor kettle brick lining partly embeds between the internal layer brick of kettle brick lining internal layer.So both having solved steel plate wards off plumbous peripheral lining brick wall-retaining structure and occurs brick easily break, fall the problem of brick and the titanium plate barricade drawback of burning easily under the high-concentration oxygen environment in reactor in actual production, solution forms vortex in the time of can avoiding stirring again, cause material suspended problem, help stirring, promote the carrying out that react, thereby raising leaching rate, help producing, also reduced the device fabrication cost simultaneously, reduced maintenance of equipment work amount, played important effect developing enterprise, reduction running cost and boosting productivity.
