The combinative alkali ammonium chloride producing and crystallizing device comprises a cold separation crystallizer. An outlet at the lower part of the cold separation crystallizer is connected with a feed inlet of a thickener through a pipeline. A discharge hole of the thickener is connected with a centrifuge through a pipeline. The combinative alkali ammonium chloride producing and crystallizing device is characterized in that the lateral surface of the upper part of the cold separation crystallizer is provided with a first overflow port; the first overflow port is connected with a salting-out crystallizer through a pipeline; an outlet at the lower part of the salting-out crystallizer is connected with a second thickener through a pipeline; and an outlet of the second thickener is connected to an inlet of the cold separation crystallizer through a circulating pipe. The cold separation crystallizer has a stable solid-to-liquid ratio. The crystallizers cannot take away materials. The combinative alkali ammonium chloride producing and crystallizing device can separate out large ammonium chloride crystalline particles and has the advantages of stable cold separation temperature, high output and low energy consumption. The production capacity of the single set of system reaches 1,050 tons of ammonium chloride per day.
Description
Technical field
The utility model relates to a kind of chemical production equipment, specifically a kind of alkali Production of Ammonium Chloride crystallization apparatus.
Background technology
Connection alkali process for producing chloride is the ammoniacal liquor that connection alkali production equipment comes out to be added salt carry out crystallisation by cooling and separate out ammonium chloride in cool crystallizer.Used equipment is generally the inner-cooled cool crystallizer that has chuck or coil pipe, and cooling is analysed after rolling and carried out stiff by pipe-line transportation to the stiff device, and then separates to separating centrifuge by pipe-line transportation.This complexes have advantage simple in structure, easy to operate.But it has cold analysis temperature instability, crystallizer solid-to-liquid ratio instability, and crystallizer is with material easily, and the less shortcoming of separating out of ammonium chloride crystals particle is separated with centrifugal extension set the stiff in later stage and to be caused difficulty, and it is little therefore to have throughput, the shortcoming that energy consumption is high.Therefore inventing a kind of novel alkali Production of Ammonium Chloride crystallization apparatus is highly profitable.
Summary of the invention
Technical problem to be solved in the utility model is exactly the defective that exists at existing connection alkali Production of Ammonium Chloride device, a kind of alkali Production of Ammonium Chloride crystallization apparatus is provided, it has the cold analysis temperature-stable, and the ammonium chloride crystals particle of separating out is big, can satisfy the big cycle volume production requirement.
The technical solution of the utility model is achieved in that it comprises cool crystallizer, the lower part outlet of cool crystallizer is connected by the opening for feed of pipeline with the stiff device, the discharge port of stiff device is connected with whizzer by pipeline, it is characterized in that: the upper side of described cool crystallizer has first overflow port, first overflow port is connected with salting-out crystallizer by pipeline, the lower part outlet of salting-out crystallizer is connected with the second stiff device by pipeline, and the outlet of the second stiff device is connected to the import of cool crystallizer by circulation tube.
The utility model technical scheme preferably is: the upper side of described cool crystallizer has second overflow port, and second overflow port is connected with the import of external condenser by circulating line, and the outlet of the external condenser recycle pump interior with being contained in cool crystallizer is connected; Be equipped with in the described salting-out crystallizer and stir and the salt inlet pipe bottom of the oblique insertion salting-out crystallizer of salt inlet pipe.
Cool crystallizer solid-to-liquid ratio of the present utility model is stable, and crystallizer is not with material, can separate out bigger ammonium chloride crystals particle, and it has the cold analysis temperature-stable, and the big advantage of low energy consumption of output, single cover system throughput Dagri are produced 1050 tons of ammonium chlorides.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model comprises cool crystallizer 1, the lower part outlet of cool crystallizer 1 is connected by the opening for feed of pipeline with stiff device 2, the discharge port of stiff device 2 is connected with whizzer 3 by pipeline, the upper side of described cool crystallizer 1 has first overflow port 4, first overflow port 4 is connected with salting-out crystallizer 5 by pipeline, the lower part outlet of salting-out crystallizer 5 is connected with the second stiff device 6 by pipeline, and the outlet of the second stiff device 6 is connected to the import of cool crystallizer 1 by circulation tube 7.The upper side of described cool crystallizer 1 has second overflow port, 8, the second overflow ports 8 and is connected by the import of circulating line with external condenser 9, and the outlet of external condenser 9 recycle pump 10 interior with being contained in cool crystallizer is connected; As shown in Figure 2, stirring 11 and salt inlet pipe 12 are housed, the bottom of salt inlet pipe 12 oblique insertion salting-out crystallizers 5 in the described salting-out crystallizer 5.
The ammoniacal liquor that connection alkali process is come joins in the cool crystallizer, carries out heat exchange by circulating in the external condenser 9 of propeller pump with liquefied ammonia, the temperature when making the temperature of cool crystallizer reach ammonium chloride to separate out.Take out ammonium chloride then and enter whizzer through stiff device 2 stiffs and carry out separation removal moisture content for 3 li, be transported to the packing warehouse through belt.
Salt is delivered in the salting-out crystallizer, and the circulation by propeller pump is constantly dissolved salt.Separate out ammonium chloride through common-ion effcet, enter the second stiff device, 6 stiffs after the taking-up.Again in pump suction cool crystallizer 1, cyclic production ammonium chloride and so forth.
