Specific embodiment
With reference to the accompanying drawing 1,2 and specific embodiment the utility model is described in detail.
A kind of economic benefits and social benefits titanium liquid enrichment facility, including level-one preheater, second level preheater, 1st effective evaporator, 2nd effect evaporator,
Feed pump, transfering material pump, discharging pump and surface condenser；The feed pump is connect with level-one preheater feed inlet, level-one preheater
Discharge port connects second level preheater feed inlet, and second level preheater discharge port connects 2nd effect evaporator feed inlet, and 2nd effect evaporator goes out
Material mouth connects 1st effective evaporator feed inlet by transfering material pump, and 1st effective evaporator discharge port connects discharging pump feed inlet；One effect evaporation
The heater of device is connect with heat source, and the steam (vapor) outlet of 1st effective evaporator and the heater of 2nd effect evaporator connect, 2nd effect evaporator
Steam (vapor) outlet connect with surface condenser；The 1st effective evaporator condensation water out is connected by the first water pump and second level preheater
It connects, 2nd effect evaporator condensation water out is connect by the second water pump with level-one preheater.It is connected on the surface condenser true
Sky pump.
The 1st effective evaporator, 2nd effect evaporator heater include primary heater and secondary heater, described one
Effect evaporator, 2nd effect evaporator vapour liquid separator top be equipped with board-like demister, lower part is equipped with volute structure feeder；
The primary heater is connected between volute structure feeder entrance and circulating-pump outlet, and secondary heater is connected on vapour-liquid point
It is recycled between material liquid outlet and pump entry from device.
Working principle: diluted Ti solution is pumped into level-one preheater with feed pump, is preheated with the condensed water that 2nd effect evaporator is discharged, then
Into second level preheater, after being preheated with the condensed water that 1st effective evaporator is discharged, into 2nd effect evaporator, forced-circulation evaporation.It is dense
Concentrate after contracting is pumped into 1st effective evaporator through transfering material pump, and forced-circulation evaporation is concentrated into after needing concentration to be achieved, with discharging
It is pumped into dense titanium liquid storage tank.By boiler Lai saturated steam or hot water enter 1st effective evaporator heater shell side heat by two
The feed liquid of evaporator is imitated, heated feed liquid enters flash distillation, the secondary steaming flashed off in the vapour liquid separator of 1st effective evaporator
Vapour enters the shell side of 2nd effect evaporator heater, the feed liquid that heating is come by second level preheater, and the feed liquid of heating enters two effects and evaporates
Flash distillation in the vapour liquid separator of device, the secondary steam flashed off enters the shell side of surface condenser, with what is be pumped by cooling water pump
Circulating water is discharged after so that its condensation, condensed water is discharged into condensation water pot with draining pump.Uncooled incoagulable gas vacuum
Pumping goes out.Guarantee that whole system is evaporated under negative pressure.
The utility model one is imitated, the setting of the heater of 2nd effect evaporator is different from traditional forced-circulation evaporator, is passed
The outlet of circulating pump is arranged in the heater of the forced-circulation evaporator of system.The heater of the utility model is designed to two groups, point
It is not mounted on the export and import of circulating pump.Under conditions of identical heat transfer area and identical tube side flow velocity, this is practical new
The flow of the forced circulation pump of type is only the half of traditional design, and operation power is the half of traditional design.And it greatly reduces
The cost of circulating pump has saved investment.
The utility model is in an effect, the board-like demister of top design of the vapour liquid separator of 2nd effect evaporator, by vapour-liquid
The secondary steam of separator discharge is introduced into plate separator, and steam flow horizontal direction enters, droplet plate type demister lip ring
It intercepts, under gravity and steam flow effect, is discharged vertically downward, reaches vapor-liquid separation.The secondary steam of discharge is free of droplet, can be with
Guarantee the outer surface non-scaling of the heat exchanger tube of 2nd effect evaporator heater and surface condenser.The condensed water of discharge is free of feed liquid,
It can be used as process water use.Reach zero-emission, it is free from environmental pollution.
One effect, the feed liquid of 2nd effect evaporator of the utility model enter the inlet design of vapour liquid separator into volute structure.
Compared with the tangential entry of traditional design, resistance is reduced, and vapor-liquid separation effect is much better than tangential entry structure, reduces two
Entrainment of the secondary steam in vapour liquid separator in uphill process.
Above-described embodiment, the only preferred embodiment of the utility model not are used to limit the implementation model of the utility model
It encloses, therefore all equivalent variationss done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
