Abstract
The utility model discloses a continuous brine purifying device adopting a lime-mirabilite-flue gas method. The continuous brine purifying device adopting the lime-mirabilite-flue gas method is characterized by comprising a pulping tank, a causticization reaction tank, a first sedimentation separator, a buffer tank, a carbonization tower and a secondary sedimentation separator which are sequentially connected, wherein the carbonization tower is provided with an air inlet pipe, and a flue gas purifying device is arranged on the air inlet pipe. The continuous brine purifying device adopting the lime-mirabilite-flue gas method adopts a continuous brine purifying production process, less equipment is used, and production cost is reduced. Brine purification is carried out by adopting continuous lime-flue gas, and cheap lime and CO2 in the flue gas are fully utilized, so as to achieve the aim of removing calcium and magnesium, so that brine purifying cost is greatly reduced, less industrial waste gas is discharged, and the environment is protected.
Description
Technical field
The utility model relates to a kind of bittern purifying device, particularly the continuous bittern purifying device of a kind of lime-saltcake-stack gas method.
Background technology
Present bittern purifying technology is step production technique, there is no the production technique of the bittern purifying that carries out continuously truly.The problem that existing production technique exists is: technology is discontinuous, the energy consumption height; Because intermittent reaction, the surge tank number of employing is many, has increased the energy consumption of producing.
Summary of the invention
The utility model provides a kind of lime-saltcake-stack gas method continuous bittern purifying device for solving the technical problem that exists in the known technology, this device can improve the state of the art that bittern purifying is produced, cut down the consumption of energy, improve plant factor, and then reach the purpose that reduces the bittern purifying production cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the continuous bittern purifying device of a kind of lime-saltcake-stack gas method, comprise the making beating jar, causticizing reaction jar, first settlement separator, surge tank, carbonating tower and second settlement separator that connect successively, described carbonating tower is provided with inlet pipe, on the described inlet pipe effluent gas purification equipment is installed.
Described first settlement separator is the mud subsider.
Described second settlement separator is the mud subsider.
Advantage and the positively effect that the utlity model has are:
1) at first adopts continuous bittern purifying production technique, reduced the equipment that uses, reduced production cost.
2) adopt continuous lime-stack gas to carry out bittern purifying, taken full advantage of cheap lime and the CO in the stack gas
2, to reach the purpose of deliming, magnesium, this not only greatly reduces the cost of purified brine, and has reduced the discharging of industrial gaseous waste, has protected environment.
In a word, the utility model has improved existing intermittent type bittern purifying production technique, can reach energy saving purposes, can improve usage ratio of equipment again, simultaneously, can reduce exhaust gas emission again.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, making beating jar, 2, the causticizing reaction jar, 3, first settlement separator, 4, surge tank, 5, carbonating tower, 6, second settlement separator, 7, effluent gas purification equipment.
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, the continuous bittern purifying device of a kind of lime-saltcake-stack gas method, comprise the making beating jar 1, causticizing reaction jar 2, first settlement separator 3, surge tank 4, carbonating tower 5 and second settlement separator 6 that connect successively, described carbonating tower 5 is provided with inlet pipe, and effluent gas purification equipment 7 is installed on the described inlet pipe.
In the present embodiment, described first settlement separator 3 and described second settlement separator 6 are for being the mud subsider.
Principle of work of the present utility model is:
In the making beating jar, finish the lime making beating, with pump slurry is squeezed into the causticizing reaction jar, with the metabisulfite solution and the bittern that feed, carry out causticizing reaction, the slip that reaction is obtained all feeds in first settlement separator then, wherein lower floor's mud feeds the mud ditch, supernatant liquid is squeezed in the carbonating tower with pump, react with the stack gas that process purifies, the slip that reaction obtains all feeds in second settlement separator, wherein lower floor's mud feeds the mud ditch, and supernatant liquid is the bittern of purification, can directly go to the vacuum salt production system.
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.
