Description
Technical field
The utility model relates to the oxygen jet structure that is used for the horizontal reacting still.
Background technology
It is reactor that zinc ore concentrate oxygen is pressed the major 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 singularity.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), anticorrosion barrier film (about 5～6mm is thick), the two-layer acid-resistant thermotolerant ceramic brick of liner (the about 180mm of total thickness); Reactor is interior to be five working spacess that top is interconnected along the still longitudinal subdivision, and each working spaces 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 working spaces in reactor, enters next working spaces through the barricade overflow, discharges to the 5th working spaces.Each working spaces's upper gas intercommunication, each working spaces 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 ore concentrate is leached in waste electrolyte.
The oxygen jet project organization of aerating oxygen is generally in the tradition reactor: the oxygen jet parts are titanium material material entirely.In the pressure leaching process of zinc ore concentrate, once attempted many materials and prevented 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 ore concentrate pressure leaches, must use pure oxygen, therefore because the control of the feeding amount of oxygen is improper, titanium material incendiary situation happens occasionally in the reactor.In addition, the exit end of oxygen jet also is provided with oxygen distribution ware in reactor, makes oxygen be evenly distributed, promote the purpose completely of reacting in order to reach.Production practice for many years prove that this structure in use has tangible weak point.The service condition that the oxygen of this structure is taken in production practice is: at first, high pressure, swiftly flowing oxygen are when the aerating oxygen nozzle, oxygen directly contacts with the titanium pipe internal surface of oxygen jet, how to prevent the burning of titanium material, is a major issue guaranteeing the reactor safe operation; Secondly, oxygen distribution ware has been installed at the outlet position of oxygen jet in the reactor, and oxygen distribution ware installing and fixing very in reactor bothers, and oxygen distribution ware is easy to get loose under the strong mixing situation; Stopping up often appears in the operation use in last oxygen distribution ware.When stopping up, part is difficult for finding that this moment, gas distribution was inhomogeneous; When all stopping up, can only stop still and handle, dismounting and maintenance be very inconvenience all.
Along with the zinc ore concentrate wet method smelting process in the wideling popularize and using of China, security, reliability and accessibility that reactor uses are had higher requirement.
The utility model content:
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of more safe and reliable, simple to operate, installation and maintenance convenient, oxygen utilization efficient is high horizontal reacting still oxygen jet structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of oxygen jet structure that is used for the horizontal reacting still, oxygen jet is arranged at the bottom centre position of each compartment in the horizontal reacting still, it is characterized in that the body of described oxygen jet is formed at the polytetrafluoroethyllining lining sleeve pipe of titanium pipe by being positioned at outer field titanium pipe and liner.
As preferred version, oxygen jet installation site at reactor is provided with the oxygen jet sleeve pipe, accordingly, be welded with in the body of the oxygen jet outside and be used for the flange of fixedlying connected, wherein flange 16MnR flange titanium lined plate more preferably with this oxygen jet sleeve pipe.This design is not directly fixed on the kettle of reactor oxygen jet, but is connected on the sleeve pipe by flange and bolt, is convenient to disassembled and assembled freely.
Described oxygen jet puts in 200～400mm in the kettle brick lining.
What the polytetrafluoroethyllining lining sleeve pipe adopted is that thickness is the polytetrafluoroethyllining lining sleeve pipe of 10～20mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model oxygen jet is installed in the bottom centre position of interior each compartment of kettle of horizontal reacting still, oxygen jet to put in the kettle brick lining 300mm long about, oxygen distribution ware is not set in kettle, directly add strong mixing by whipping appts efficiently, make oxygen in kettle from the bottom to around and the top rapid diffusion, path length is evenly distributed, promotion oxygen is thorough the still internal reaction, improve oxygen utilization rate, make reaction heat even simultaneously, avoided using all drawbacks of oxygen distribution ware.
The outside body of described oxygen jet is selected the titanium pipe for use, adopts 16MnR flange inner panel lining titanium plate with the flange that the titanium pipe welds mutually, so not only can reach etch-proof purpose but also can save cost, and is economical and practical; Simultaneously also served as a contrast a polytetrafluoroethyllining lining sleeve pipe in titanium pipe inside, because polytetrafluoroethylmaterial material has a series of good use propertieies: high temperature resistant---use working temperature to reach 250 ℃; Corrosion-resistant---to most of pharmaceutical chemicalss and solvent, show inertia, energy strong alkali-acid resistance, water and various organic solvent; High lubricated---be frictional coefficient the lowest in the solid material; Do not adhere to---be surface tension minimum in the solid material, do not adhere to any material; Low heat conductivity energy---thermal conductivity is 0.256W/m.K, only is 1/6 of acid-resistant and heat-resistant ceramic tile; Uninflammability---limited oxygen index is below 90.Therefore the oxygen that adopts the polytetrafluoroethyllining lining sleeve pipe both can avoid high speed, high temperature, high pressure to feed directly contacts, avoids burning with the titanium pipe, when oxygen stops to feed, can play insulation effect to the ore pulp that is deposited in the oxygen jet again, prevent that ore pulp Yin Wendu in the oxygen jet from descending excessive and solidify and stop up.
Horizontal reacting still oxygen jet described in the utility model is not directly fixed on the housing of reactor, but is connected by flange and bolt on the oxygen jet sleeve pipe of reactor, be can disassembled and assembled freely independently parts.Occur stopping up and fault in the operation use in case oxygen jet occurs, dismounting and maintenance are all very convenient.
In sum, the oxygen jet structural safety that is used for the horizontal reacting still described in the utility model is reliable, simple to operate, installation and maintenance convenient and oxygen utilization efficient height.
