The device comprises a crystallizer, a circulating pump, a cool exchanging device, a heat preservation settler, a buffer tank, a clean liquid pump, an agitation tank, a size pump, a filter press, a mother liquor tank, a mother liquor pump and a potassium chloride producing and evaporating system which are sequentially connected. The device has the advantages that due to adoption of the technology for producing the potassium chloride without adding old brine, new products are added for salt chemical engineering enterprises, the utilization rate of the potassium chloride production device is increased, and the purposes of energy conservation and consumption reduction are achieved in the potassium chloride evaporation and concentration process.
Description
Technical field
The utility model relates to a kind of device of producing Repone K, and particularly a kind of salt-making mother liquor is not converted the device that halogen is produced Repone K.
Background technology
Present sea salt district Repone K production all is to be raw material with the mother liquor of discharging after the salt manufacturing, salt-making mother liquor is before entering Repone K production system evaporation concentration, all will be according to a certain percentage be blended into old halogen in the mother liquor and (separate out the mother liquor behind the carnallitite, be main component with the magnesium chloride), the mother liquor of converting halogen is in order to improve the concentration ratio in when evaporation, improve the potassium chloride concentration in the complete evaporation of liquid, sylvite is separated out in advance when avoiding evaporating, but convert halogen and cause the idling of a part of feed liquid in equipment, increased the power and energy consumption of production process; In addition, even so, in evaporative process, also can separate out a large amount of high and tow temperature salts, one ton of Repone K of general every product will be separated out eight to ten tons high and tow temperature salt, especially the sulfuric acid monohydrate magnesium granules in the high temp. salt composition is very thin, take away 30% Repone K nearly during separation, cause the yield of present Repone K production generally about 70%.
Summary of the invention
The utility model provides a kind of salt-making mother liquor not convert the device that halogen is produced Repone K for solving the technical problem that exists in the known technology, this device can cut down the consumption of energy, increase operation rate, improve the yield of Repone K product, and then reach the purpose that reduces the Repone K production cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of salt-making mother liquor is not converted the device that halogen is produced Repone K, comprises the crystallizer, recycle pump, cold-exchange, insulation settling vessel, surge tank, clear liquid pump, steel basin, mashing pump, pressure filter, mother liquor tank, mother liquor pump and the Repone K production vapo(u)rization system that connect successively.
Described cold-exchange is the tubulation cold-exchange.
Described pressure filter is plate-and-frame filter press.
Advantage and the positively effect that the utlity model has are:
One) by after the two step sulphur removal, Repone K production vapo(u)rization system does not need to be blended into old halogen, makes the treatment capacity of vapo(u)rization system reduce 1/4th to 1/3rd.
Two) under the Repone K yield is up to 85% prerequisite, make the evaporation termination boiling point of vapo(u)rization system under normal pressure by at present traditional 128 ℃, be reduced to 124～126 ℃; Can reduce the energy consumption of vapo(u)rization system.
Three) solid is different from traditional sodium-chlor and sulfuric acid monohydrate magnesium compound based on sodium-chlor in the slurry of discharging after the complete evaporation of liquid insulation sedimentation, and the rate of loss that makes slurry of solids carry Repone K secretly is reduced to below 5% by 30%.
Four) complete evaporation of liquid is incubated the evaporation concentration of obtaining after the sedimentation and finishes clear liquid through crystallisation by cooling, the decomposition washing obtains the yield of Repone K and brings up to 85% by 70% of present traditional mode of production.
In sum, the utility model adopts and not to be blended into old halogen and to carry out the technology that Repone K is produced, and can increase new product for chemical enterprises, can improve the utilization ratio of Repone K production unit again, and reaches energy saving purposes for the evaporation concentration of Repone K.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of salt-making mother liquor is not converted the device that halogen is produced Repone K, comprises the crystallizer 1, recycle pump 2, cold-exchange 3, insulation settling vessel 4, surge tank 5, clear liquid pump 6, steel basin 7, mashing pump 8, pressure filter 9, mother liquor tank 10, mother liquor pump 11 and the Repone K production vapo(u)rization system that connect successively.
Described cold-exchange 3 is the tubulation cold-exchange in the present embodiment.Described pressure filter 8 is plate-and-frame filter press.
Principle of work of the present utility model:
Salt-making mother liquor is introduced into crystallizer and carries out freezing, the refrigerant medium in the tubulation cold-exchange with the raw material indirect cold exchange, and by recycle pump feed liquid is constantly circulated, after feed temperature is qualified, enter the insulation settling vessel, isolated slurry removes to produce magnesium sulfate heptahydrate, and the clear liquid of overflow enters surge tank and changes chemical reaction sulphur removal operation over to by clear liquid pump; Clear liquid reacts with the calcium chloride that adds in steel basin, reacted slurry is sent into by mashing pump and is carried out solid-liquid separation in the plate-and-frame filter press, isolated solid phase is terra alba, and liquid phase enters mother liquor tank, squeezes into the Repone K vapo(u)rization system by the mother liquor pump again and carries out Repone K production.The solid phase terra alba is used for the refining gypsum series product of producing.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
